Federal legislation requires equitable access to education for all students at all levels, including in the postsecondary setting. While there have been a few studies in the chemistry education research literature base focused on how to support students with specific disabilities, this work seems to exist as a separate stream of research without direct impact on curriculum development and the overall community. This study focused on investigating how well three sets of general chemistry curricular materials support variations in students’ abilities, interests, and needs. To accomplish this, we compared the curricular materials with the Universal Design for Learning (UDL) framework, which describes steps to account for variations in ability among learners during curriculum development. The UDL framework is organized into three guidelines (multiple means of representation, action and expression, and engagement), further delineated by nine principles and thirty-one finer-grained checkpoints for designing courses. We looked for examples of enactment of the UDL checkpoints in a representative sample of activities. Across all three sets of curricular materials, only four of the thirty-one checkpoints were enacted in at least 75% of the activities, indicating high enactment. On the other hand, eleven of the checkpoints were enacted in less than 25% of the activities, indicating low enactment. Overall, there is much room for improvement in consistently providing support for learner variation within these general chemistry curricular materials. We argue that some of the burden of making curricular materials supportive of all students lies with curriculum developers and provide recommendations for improving support and accessibility.
We argue for the use of alternative frameworks for considering variation among learners: Universal Design for Learning (UDL) and ability profiles. UDL provides a framework for developing flexible teaching strategies and materials that support diverse learning needs (CAST, 2011). “Ability profile” is a useful way to consider learner variation across multiple dimensions such as physical, cognitive, metacognitive, motivational, and affective (Azevedo, 2015; Thorius and Santamaria Graff, 2018). Some students, such as dominant language learners and those with diagnosed disabilities, may have uniquely large variations compared with their peers. More generally, all students vary across the multiple dimensions of ability, interest, and need. By using UDL to design curricular materials, support can be provided to all students.
A common misconception is that “UDL is just good teaching” (Edyburn, 2010, p. 38). Following this belief, one might expect that well-designed, research-based teaching strategies and materials will naturally enact many UDL strategies. Edyburn calls for researchers to “find ways to define and measure implementation of UDL in order to discern when it is being implemented and when it is not” (Edyburn, 2010, p. 38). We selected three sets of high quality chemistry learning materials to explore the extent to which their curricular materials enact strategies aligned with the UDL framework. In all cases, the curriculum developers focused on important aspects of student learning and did not express an intentional focus on UDL. Thus, this analysis serves as a test of the misconception that “UDL is just good teaching” and not of the overall strength of any of the selected curricula.
We use the case of students with disabilities to illustrate the need to provide embedded options and support so that all learners, who vary in abilities, needs, and interests, can engage with our curricular materials. Federal law mandates equitable access to postsecondary education for students with disabilities. Recent lawsuits highlight examples of inaccessible pedagogies and curricular materials that the reader likely finds familiar, such as classroom response systems (Zou, 2011) and online homework (Dudley v. Miami University). While the law only requires access options when a barrier is present for a specific student, some universities and instructors may decide to require fully accessible courses regardless of enrollment; for example, universities are discussing how to work together to vet technologies for accessibility (McKenzie, 2017). Additionally, in a recent settlement the U.S. Department of Justice has required a university to make all materials accessible, specifically requiring “the University will only purchase, develop or use technology and instructional materials that allow persons who are blind or who have other vision disabilities the equal opportunity to access, use, and avail themselves of such technology or instructional materials in as full, equal, and independent a manner as persons without disabilities” (Louisiana Tech University v. United States of America, 2013). If we want all students to participate in the scientific community, we must provide access in our courses in a manner that communicates that each student is an anticipated and welcome participant in our community.
In the United States, legislative mandates require that students with disabilities have equal access to postsecondary education. The reauthorized Individuals with Disabilities Education Improvement Act of 2004 requires secondary institutions to prepare students with disabilities for further education. Provisions in the Higher Education Opportunities Act of 2008 (PL 110-3145) further expanded postsecondary education opportunities for students with disabilities by developing and improving postsecondary programs and extending federal financial aid opportunities for students with disabilities to attend postsecondary institutions (Council for Exceptional Children, 2008).
Evidence suggests many students with disabilities in postsecondary education have difficulty completing their programs. Data from National Longitudinal Transition Study-2 (NLTS-2) showed students with disabilities had lower rates (34%) of four-year college completion than their nondisabled counterparts (51%; Newman et al., 2011). The completion rates of any postsecondary education by students with disabilities is more than 10% lower (41%) than for students without disabilities (52%; Newman et al., 2011).
Students with disabilities face unique challenges when transitioning to postsecondary education, as they are responsible for requesting and managing accommodations by self-disclosure (Finn et al., 2008; Newman and Madaus, 2015). A recent study found only 24% of college students who previously received special education services in high school also disclosed their disabilities to postsecondary schools (Cortiella and Horowitz, 2014). Students may not disclose their disability for a variety of reasons such as fearing disability-specific negative stereotypes, judgement by peers, or increased academic anxiety (Trammell, 2009), or may struggle to produce the documentation required to access services at the postsecondary level (Cortiella and Horowitz, 2014). Students with disabilities are frequently underprepared in self-advocacy and lack the compensation strategies (e.g., self-regulation and study skills) necessary to deal with large STEM courses which require more organizational, goal-setting, and executive function skills (Parker and Boutelle, 2009). Many students with disabilities may also lack effective communication skills to interact with professors or disability service staff in order to acquire or use accommodations to support their learning needs (Bae, 2007).
Faculty attitudes are one of the major impediments to success in higher education for students with disabilities (Rao, 2004). Lack of knowledge about disabilities or of inclusive teaching strategies may unduly influence faculty perceptions and result in stereotyping or fear of lowering academic quality standards. In particular, faculty have been found to have more negative attitudes toward psychiatric and attention (e.g., attention deficit disorder or attention-deficit/hyperactivity disorder) disabilities than physical disabilities, which may be the result of less understanding of these specific disabilities (Hindes and Mather, 2007). Lombardi (2010) reported that when faculty have a greater knowledge about disabilities, they are more likely to hold positive attitudes toward students with disabilities in four-year colleges and universities.
Investigation of faculty knowledge has focused mostly on knowledge of legal requirements pertaining to students with disabilities in higher education, and some studies suggest faculty in higher education have limited knowledge of disability laws (Vasek, 2005; Vogel et al., 2008). Studies examining the areas needed for professional development at higher education institutions have routinely suggested faculty and staff need more opportunities to gain knowledge about disability and the best ways to create a more inclusive institutional environment. Similarly, researchers have found faculty give high ratings to the importance of program content aimed at increasing knowledge of the needs of students with disabilities and education on disability law and accommodations (Debrand and Salzberg, 2005), as well as topics on universal design instructional techniques (Cook et al., 2007, 2009). However, results from Behling and Linder (2017) provide evidence that faculty members find it difficult or unnecessary to attend informational trainings related to access or to the specific needs of students with disabilities. Moreover, the results suggest faculty members tend to think anything beyond providing basic accommodations to students is not their job (Behling and Linder, 2017).
The consensus of the literature suggests programs designed to improve attitudes towards students with disabilities should increase knowledge of laws, student needs, and resources available, and should give practical ideas and applications for accommodative teaching strategies, such as universal design (Wynants and Dennis, 2017). This literature also suggests that curriculum developers should not rely on individual faculty to adapt curricula to support students with disabilities.

The purpose of this study was to determine how well general chemistry curricular materials support students with varying abilities, needs, and interests through the lens of UDL. We did not examine the aspects of the curricular materials that are the hallmarks and focal points as intended by their developers. For example, the Chemistry, Life, the Universe, and Everything (CLUE; Cooper and Klymkowsky, 2017) curriculum presents the chemistry topics around four central themes in a radically different manner than more traditional texts. This is independent of the accessibility of the curricular materials which was the focus of this study. We selected three sets of curricular materials and looked for examples of the UDL checkpoints in a representative set of activities. This investigation was intended to determine the state of general chemistry courses’ support of the variations in learners’ abilities, needs, and interests as well as to make suggestions for future curricula. The research questions guiding this inquiry were:
(1) How do general chemistry curricula support the diversity of learners as measured by their level of enactment of Universal Design for Learning checkpoints?
(2) How can general chemistry curricula be modified to better support all students (and thereby enact more of the Universal Design for Learning checkpoints)?
Research on the implementation of the CLUE curriculum has shown that students enrolled in CLUE show “marked improvements” in drawing Lewis structures and in their ability to decode the information in the Lewis structures, as compared with a statistically equivalent group of students in a traditional chemistry class (Cooper et al., 2012). In a longitudinal comparison, students enrolled in a CLUE course made connections between structure and properties earlier than a matched cohort of students in a traditional chemistry class (Underwood et al., 2016). Also, students enrolled in a CLUE course more quickly understood the concept of inter-molecular forces and maintained this correct understanding longer than their non-CLUE peers (Williams et al., 2015). Overall, the research indicates that when enrolled in a CLUE course, students are more likely to understand traditionally difficult general chemistry topics and to maintain their understanding into future courses.
Little research has been published to date regarding the implementation of an atoms-first text compared to a traditional chemistry text. Esterling and Bartels (2013) found instructors need to gain experience with the atoms-first approach and may initially find fewer students passing the first and second quarters of the general chemistry series. With one year of instructor experience, the researchers found the passing rate had “more than reversed” in the first quarter, but that challenges persisted in the second quarter.
Mastering Chemistry is an online homework system with hundreds of activities, including quantitative problems, conceptual questions, and tutorials. Mastering Chemistry is designed around three learning principles: support learning via scaffolding; support knowledge retention; and customize content through adaptivity (Mastering Chemistry, 2017).
Eichler and Peeples (2013) found that students who used the Mastering Chemistry online homework system for an entire semester of general chemistry had an 11 point increase in their final exam scores when compared to a similar cohort of students who did not use an online homework system. In another study, 85% of health science students indicated that Mastering Chemistry was a useful tool in improving their understanding and 77% of the same students reported that the timely feedback provided by the system was helpful (Wahab and Thomas, 2015).
The POGIL pedagogy has been widely implemented in secondary and post-secondary settings and across many STEM disciplines, including chemistry, biochemistry, biology, computer science, engineering, and calculus. The effectiveness of POGIL has been assessed at a range of institutions of different class sizes and different courses. Moog et al. (2006) state that implementation of POGIL:
“generally results in lower student attrition from the courses using POGIL than courses using traditional methods (with attrition being considered earning a grade of “D” or “F” or withdrawing from the course), along with student content mastery that is at least as high or higher than that for students in comparable traditional sections” (p. 46).
Research has also demonstrated that inquiry-based instruction in chemistry has many advantages including improved Drop–Fail–Withdraw (DFW) rates (Farrell et al., 1999), improved test performance (Lewis and Lewis, 2005), and increased student confidence (Schroeder and Greenbowe, 2008).
The Chemistry: Guided Inquiry (CGI) book is composed of 60 activities for students to work through. The activities include a description of a chemical model, warm-up questions, critical thinking questions, problems, and exercises. This is the only curricular component in the POGIL-CGI curricular materials and was included in our sample.
Mastering-SP includes the atoms-first Chemistry: Structure and Properties textbook and the Mastering online homework system items. In addition to the text, the Chemistry: Structure and Properties textbook includes text, figures, solved example problems, and key concept videos to present information. The Mastering online homework system includes items that can be assigned to students, disaggregated by textbook section. The items come in multiple forms: tutorials, in which new information is presented for students as they answer questions; activities, which are like tutorials but with new information presented in video format; test bank questions, which are exam-style questions; reading questions, which are multiple choice questions focusing on content directly presented in the textbook; and end-of-chapter questions. All of these curricular components, except the test bank questions, were included in our analysis. We excluded test bank questions from our analysis because these are typically intended to assess learning instead of helping students learn.
CLUE includes a textbook, in-class worksheets, recitation assignments, lecture slides, and mock exams. The textbook has a traditional layout, but the information presented is markedly different than a traditional chemistry book (see the description of the CLUE curriculum is Section 2.1.1). The textbook also includes “questions to answer”, “questions to ponder”, and “questions for later” for students to work through. The in-class worksheets and recitation questions are intended to be used during class time and provide practice problems for students. The recitation questions are used in the traditional recitation part of the course and the worksheets are used during regular class time. The lecture slides are written to be used with a classroom response system (i.e., there are imbedded questions for students to respond to). The test bank includes at least three exams for each of the two semesters of the course with multiple choice and short answer questions in each. All of these curricular components, except the mock exam questions, were included in our analysis.
We used the UDL Guidelines 2.0 Full-Text Representation (CAST, 2011) as the basis for our UDL checkpoint operationalizations. This document provides detailed descriptions of each principle, guideline and checkpoint, including a definition and examples of how the checkpoints could be implemented in a classroom, and includes an overall description of the concepts behind UDL. For example, the implementation examples for checkpoint 2.1 (Clarify vocabulary and symbols) include pre-teaching vocabulary and symbols, highlighting how complex terms are composed of simpler components, and embedding support for understanding vocabulary and symbols in text through means such as hyperlinks to dictionaries. A full list of the operationalizations for each checkpoint are included in Appendix D.
Some of the UDL checkpoints focus on aspects of how a classroom is run that would not appear in a written text. For example, we would not expect UDL checkpoint 7.3 (Minimize threats and distractions) to appear in the student version of the written activities because it focuses on classroom culture rather than tasks the students are asked to complete. We made no assumptions about how the curricula were implemented in a classroom setting unless the curricular materials (including instructor guides) specifically described details about how it should be implemented. Therefore, the selected curricula could be implemented in a classroom in a way that enacts more of the UDL framework than is shown here. In our analysis, we track the checkpoints most directly affected by this limitation; see the Sources of Low Enactment section for more information.
The three raters then analyzed their assigned sections independently. Table 2 shows the number and percent of total textbook sections analyzed by each of the three raters. There were four possibilities for overlap in coding as shown under the Analyzed by Multiple Raters heading. At least 50% of sections in each curriculum were coded by two or more raters, and there was a minimum of 29% overlap between the physics and chemistry raters (including sections coded by all three raters). At least 13% of all textbook sections included were analyzed by all three raters.
Total | Analyzed by one rater | Analyzed by multiple raters | |||||

Chemist only | Physicist only | Chemist and physicist | Chemist and education | Physicist and education | All raters | ||
CLUE | 33 | 6 (18%) | 7 (21%) | 0 (0%) | 5 (15%) | 5 (15%) | 10 (30%) |
Mastering-SP | 51 | 7 (14%) | 7 (14%) | 14 (27%) | 8 (16%) | 8 (16%) | 7 (14%) |
POGIL-CGI | 38 | 9 (24%) | 10 (26%) | 6 (16%) | 4 (11%) | 4 (11%) | 5 (13%) |
After the independent coding, the three raters met to discuss their findings. The discussion process was completed one curriculum at a time and the co-coded sections were discussed one UDL checkpoint at a time. When disagreements arose, the reasoning behind the raters' unalignment/alignment were discussed as related to the UDL implementation guide and examples. Typically, the disagreements were resolved by refining operationalizations of the UDL checkpoint due to unique features of each curriculum. If the checkpoint operationalization refinement affected the previously completed analysis, the refinements were implemented in the previous sections in order to maintain consistency.
After discussion, most instances were agreed upon by all three raters. During the discussion process, disciplinary differences were addressed and operationalizations were refined to account for the specifics of each curricula. The physics coder's responses were included in the analysis for the few instances where disagreement persisted after discussion. Table 3 shows the results of the inter-rater reliability process as described by Gwet's AC1 metric (Gwet, 2002).

Unlike other kappa statistics, Gwet's AC1 metric does not depend on the prevalence of the trait under study, so it is more stable in cases when a code is observed very frequently or very infrequently. Gwet's AC1 ranges from 0 (meaning no agreement) to 1 (meaning perfect agreement). AC1 values between 0.61 and 0.8 indicate substantial agreement, and values greater than 0.81 indicate almost perfect agreement (Gwet, 2014). Before discussion, principles 1, 4, 7, 8, and 9 had at minimum substantial agreements between all three raters while principles 2, 3, 5, and 6 did not reach substantial agreement between all three raters. All principles after discussion had Gwet's AC1 values greater than 0.81, indicating almost perfect agreement (Gwet, 2014). Thus, we find substantial evidence to support the reliability of the data analysis after discussion.
No quantitative measures of the extent of enactment of UDL currently exist in the literature base, so we operationalized three levels of enactment for this study. We define “high enactment” as when a minimum of 75% of at least one curricular component enacted a UDL checkpoint. For example, we identified examples of checkpoint 2.1 in more than 75% of the textbook sections and lecture slide sets analyzed for the CLUE curriculum, but not in the recitation and worksheet activities. Since the curricular components work together to support student learning, we classify this type of enactment as “high.” Four checkpoints (1.1, 2.1, 2.5, and 3.2) showed consistently high enactment across all three sets of curricular materials, as shown in Table 4. Similarly, we define “some enactment” as when at least 25% of at least one curricular component aligned with the UDL checkpoint. Checkpoints 1.3, 3.4, 6.2, and 6.3 consistently showed some to high enactment across the three sets of curricular materials. Finally, we define “low enactment” as when less than 25% of all curricular components aligned with the UDL checkpoint. Eleven checkpoints (2.3, 2.4, 4.2, 5.2, 7.1, 7.3, 8.1, 8.2, 9.1, 9.2, and 9.3) showed low enactment across all three sets of curricular materials. Checkpoints 1.2, 2.2, 3.1, 3.3, 5.1, 7.2, and 8.3 showed mixed enactment across the sets of curricular materials. Additionally, Mastering-SP showed uniquely high enactment of checkpoints 4.1, 5.3, 6.1, 6.4, and 8.4. These detailed findings are listed in Tables 6, 7, and 8 in Appendix B.

Solely providing curricula in a digital format does not guarantee the curricula will be accessible because not all digital formats are equally accessible. In the present study, we have not analyzed the specific accessibility features of the digital formats. Guidance on creating accessible digital content is provided by the Web Content Accessibility Guidelines (https://www.w3.org/WAI/intro/wcag).
“. The potential energy (V) of two stationary charged particles is given by the equation above, where q1 and q2 are the charges on the particles (e.g., −1 for an electron), d is the distance between the particles, and k is a positive-valued proportionality constant.” (POGIL, p. 16)
In this excerpt all of the variables were defined, supporting students who have not yet mastered these concepts. Learners coming from different cultural and lexical backgrounds and with non-dominant native languages can have particular difficulty accessing information when words and symbols are not clearly defined.
“Atoms are neither created nor destroyed when chemical reactions take place. Therefore, the number of atoms of each element must be identical on the reactant (left) and product (right) sides of a balanced chemical reaction. Such a chemical equation is said to be atom balanced.” (POGIL, p. 171)
In this excerpt, the key vocabulary was bolded, drawing students’ attention to the term and indicating its importance. While experts can read through a text and easily identify the important features and relationships, novices typically struggle with this task (CAST, 2011). Adding support and scaffolding to assist students with the identification of the key features and relationships will especially benefit students with less background knowledge.
“The ball-and-stick model of methane shows the central carbon (black ball) attached to four hydrogens (white balls) by sticks that represent the bonds between the atoms. Although this model is probably the easiest to visualize, it is misleading because it could give the impression that bonds are like sticks holding the atoms together. It also does not represent either the actual volume occupied by the molecule or its electrostatic surface features.” (CLUE, pp. 81–82)†
This example shows a description of the image in the text, offering an alternative for the visual information. Students with difficulties interpreting diagrams or those who are visually impaired can be disproportionately affected by the presentation of information solely in a visual format.
The curricular materials could have improved enactment of this checkpoint by providing links between material learned in class and new situations as well as by assisting students with linking previously learned material with new content. Future curricula should both incorporate multiple opportunities for students to review and practice what they have learned in class, and link course material with new content and with new situations to allow for more robust generalization and transfer.
“For gravitational and electrostatic forces: Discuss what aspects are the same for each force and what are different. Be sure to indicate how the forces are different. (CLUE, Recitation 2, p. 1)”
The recitation problem provides a table to assist students in categorizing their information, reducing the executive function load on students.
We identified two discrete reasons that the UDL checkpoints had low enactment in the curricular materials: (1) low enactment that occurred because curricular materials did not best serve all students and (2) low enactment due to implementation variability, or variation in how instructors could implement the curricula. For example, in order to enact UDL checkpoint 7.3 (Minimize threats and distractions) an instructor would need to create a welcoming classroom environment that promotes inclusivity, involve all students in whole class discussions, or vary the level of sensory stimulation. These types of classroom practices were not articulated in the written components of the curricula which were examined in this study. When such practices are not addressed in the written instructional materials (e.g., instructor guides), individual instructors are left to identify and address these areas or to tacitly not address them, leaving room for variation across implementations. Returning to our example, checkpoint 7.3 (Minimize threats and distractions) manifests in the classroom culture. We encourage curriculum developers to include information related to these checkpoints in instructor guides to support instructors, as discussed in the Limitations section. We classified checkpoints 4.2 (Optimize access to tools and assistive technologies), 5.2 (Use multiple tools for construction and composition), 7.3 (Minimize threats and distractions), and 9.2 (Facilitate personal coping skills and strategies) as subject to implementation variability and expect that these checkpoints would not typically be addressed in the written curricular components.
It may seem surprising that checkpoints 3.1 (Activate or supply background knowledge) and 8.3 (Foster collaboration and community) only had mixed enactment across the sets of curricular materials. Checkpoint 3.1 was only sparsely enacted in the POGIL book because it did not regularly link concepts to previously learned material, use advanced organizers, bridge concepts with analysis, or make explicit cross-curricular connections. However, the Mastering-SP online homework end-of-chapter items enacted checkpoint 3.1 by, for example, referencing the textbook section in which the question's content was covered. Similarly, the CLUE textbook would refer back to previously covered material through statements such as “Recall in the previous chapter…” These strategies allow the students to more easily assimilate the material into their existing knowledge structures and can particularly help lower barriers to success for learners who lack background knowledge or understanding of the relevance of the background knowledge they possess.
Checkpoint 8.3 (Foster collaboration and community) had mixed alignment because the POGIL-CGI and Mastering-SP curricular materials explicitly state that students should work in groups as they work through the given activities. The CLUE curricular materials do not explicitly require group work and thus did not enact this checkpoint. We only examined the written portions of the curricular materials and did not make assumptions about how the curricular materials would be implemented in the classroom. Thus, it is possible that a CLUE classroom would align with this checkpoint, but analyzing classrooms was beyond the scope of this study.
Although the POGIL-CGI and Mastering-SP curricular materials explicitly promoted group work, they did not discuss how this should manifest in the classroom. In the UDL guidelines, checkpoint 8.3 describes group work that is well structured to support students. Structuring group work can help students who have difficulties with social interactions or with disabilities that affect their ability to interact with others (e.g., autism spectrum disorder, social communication disorder).
“Use molecular shape to determine polarity of a molecule.” (Tro, 2018)
By modeling for learners how to set appropriate goals, we can encourage and scaffold their goal-setting abilities.
“According to the collision model, why does increasing the temperature increase the rate of a reaction?
(A) Increasing the temperature increases the number of collisions that can occur with enough energy for the reaction to occur.
(B) Increasing the temperature causes more of the collisions to occur with the correct particle orientation for the reaction to occur.
(C) Increasing the temperature causes more particles to occupy the same amount of space which therefore increases the reaction rate.” (Conceptual Connection 14.1)
If a student chooses answer B the following feedback is given:
“Incorrect; Try Again. Increasing the temperature does not change the orientation of the collisions. You may want to review page 586.” (Conceptual Connection 14.1)
This feedback is not only timely, but it is also “substantive and informative rather than comparative or competitive” (CAST, 2011). Giving mastery-oriented feedback to students is a more productive form of assessment and can be “particularly important for learners whose disabilities have been interpreted, by either themselves or their caregivers, as permanently constraining and fixed” (p. 32). Mastery-oriented feedback not only benefits students with disabilities but benefits all students.
Another limitation is that the UDL framework does not cover all of the accommodation needs for all students who could conceivably enroll in a general chemistry course. Each student is unique and has a different ability profile. The UDL framework provides a starting point to create more accessible and accommodating classrooms for all students. However, it would be challenging to enact all of the UDL checkpoints at once.
A final possible limitation is that each set of curricular materials was composed of different components (e.g., homework questions, textbook, lecture slides), which does not allow for comparative analysis. However, our purpose in this study was not to compare general chemistry curricula to one another, but rather to map the current landscape of accessibility of general chemistry curricular materials.
We argue that some of the burden for providing all students with equal access to the curriculum falls on the curriculum developers. While a campus disability services office provides many accommodations, those are only available to students who can navigate the requirements to access these accommodations and who self-identify. Creating more inclusive curricula benefits all students. Research indicates that many postsecondary STEM faculty do not have the knowledge and skills to make the necessary accommodations to support all student needs. Also, it does not make sense for individual faculty to repeatedly make the same accommodations or for students to lose access to high quality curricula because of its inaccessibility. Edyburn (2010) states:
“A fundamental question that has yet to be addressed is whether or not the demands of daily instruction will allow teachers to function effectively as instructional designers. That is, are teachers the principal stakeholders as they design and deliver instruction in accordance with UDL principles? Or, is UDL a task for developers who make instructional products?” (p. 37)
We argue effort should continue to support faculty, staff, and administrators to become knowledgeable of and fluent in ways to accommodate learner variation in skills, interests and needs. At the same time, accessibility options and implementation guidelines should be built into high quality curricular materials to support faculty in this process. Thus, we also call on funding agencies to encourage curriculum developers to make their curricula accessible and to provide the resources needed to partner with accessibility experts.
Ultimately, who we are prepared to teach communicates who we expect to participate in the chemistry community. Instructors engage in a balancing act when they select a curriculum, considering possible conflicting factors such as content coverage, instructional design, and cost to their students. We argue that accessibility is another dimension that we must consider and suggest the UDL framework as a useful tool for curriculum developers to make progress towards enhanced accessibility.

2.2 | Define/clarify structure of equations and relationships. | “You probably recall that “like charges repel and unlike charges attract”, and that this interaction, which is known as a Coulombic interaction, depends on the sizes and signs of the charges, and is inversely proportional to the square of the distance between them (this interaction can be modeled by the equation: Fα(q1q2)/r (Coulomb's Law), where q1 and q2 are the charges on the particles and r is the distance between them). (CLUE, p. 28) | ||
2.3 | Support the decoding of text and symbols to assist with comprehension. | “In an orbital diagram, the direction of the arrow (pointing up or pointing down) represents the orientation of the electron's spin.

2.4 | Link to non-dominant language dictionaries, include definitions in non-dominant languages, etc. | See Appendix D | ||
2.5 | Use diagrams or graphs to explain/clarify key concepts. | “If the interaction is destructive, there is no stabilizing interaction. In the case of hydrogen each atom has a single (1s) orbital occupied by a single electron. As the atoms approach one another these 1s atomic orbitals interact to form two possible MOs: a lower energy, constructive or bonding MO, and a higher energy, destructive or anti-bonding MO. Notice that the bonding MO, a so-called σ1s (sigma) orbital, has electron density (that is a high probability that the electrons would be found there if we looked) between the two hydrogen nuclei. In the anti-bonding MO, known as σ1s*, the electrons are mostly not between the nuclei.” (CLUE, p. 67) | ||

It follows a zero-order reaction mechanism for the consumption of reactant R. Plot the graph of concentration versus time.

• Construct communities of learners engaged in common interests or activities | ||
• Create expectations for group work (e.g., rubrics, norms, etc.) | ||
Increase mastery-oriented feedback | 8.4 | • Provide feedback that encourages perseverance, focuses on development of efficacy and self-awareness, and encourages the use of specific supports and strategies in the face of challenge |
• Provide feedback that emphasizes effort, improvement, and achieving a standard rather than on relative performance | ||
• Provide feedback that is frequent, timely, and specific | ||
• Provide feedback that is substantive and informative rather than comparative or competitive | ||
• Provide feedback that models how to incorporate evaluation, including identifying patterns of errors and wrong answers, into positive strategies for future success | ||
Promote expectations and beliefs that optimize motivation | 9.1 | • Provide prompts, reminders, guides, rubrics, checklists that focus on: |
• Self-regulatory goals like reducing the frequency of aggressive outbursts in response to frustration | ||
• Increasing the length of on-task orientation in the face of distractions | ||
