The purpose of this research was to examine the relationships between conceptions of learning and approaches to learning in chemistry. Two questionnaires, conceptions of learning chemistry (COLC) and approaches to learning chemistry (ALC), were developed to identify 369 college chemistry-major students' (220 males and 149 females) conceptions of and approaches to learning chemistry. First, it was found that students in higher grade levels (juniors and seniors) tended to express more agreement with higher-level COLC, such as learning chemistry by transforming, than those in lower grades (freshmen and sophomores). The regression analyses, in general, revealed that the students who expressed lower-level COLC, such as learning chemistry by memorizing and preparing for tests, tended to use surface approaches to learning chemistry, whereas those students possessing higher-level COLC, that is, learning chemistry by transforming, tended to use deep approaches to learning chemistry. However, inconsistent with theoretical perspectives, this study revealed that learning chemistry by memorizing could positively predict a deep motive for learning chemistry, while learning chemistry by transforming was associated with a surface motive for learning chemistry. The special features of learning chemistry which might account for these relationships are discussed.
In general, conceptions of learning represent a coherent knowledge scheme, learning beliefs, and perceptions of associated phenomena about learning, such as ideas about learning values, learning goals, learning activities and methods, perceived features of learning tasks, and also the tasks which are handled among teachers and students in the learning process (Vermunt and Vermetten, 2004). Moreover, Reid et al. (2005) identified the three aspects of students' conceptions of learning: intention, method, and outcome. The intention aspect means that students refer to future plans or targets (such as learning as passing the subject or course); the method aspect includes students' learning methods or specific details of what they do (such as learning as focusing on course requirements and expectations); and the outcome aspect indicates students' developed procedural skills and conceptual skills, or attitudes (such as learning as understanding the subject).
Tsai (2004) has suggested that students' conceptions of learning should be viewed as academic epistemic beliefs in school, as they are related to students' beliefs about the nature of school knowledge and learning in class.
Students' approaches to learning indicate their ways of academic learning (Biggs, 1994). That is, approaches to learning also have been defined as the ways in which students process their academic tasks and thus are assumed to influence their learning outcomes (Marton and Säljö, 1976). Students who have more sophisticated epistemic beliefs may tend to employ deeper or more meaningful learning approaches such as trying to integrate the acquired knowledge. The studies by Lin et al. (2012a) and Liang et al. (2010) have supported this view. Moreover, the interplay between students' conceptions of learning and learning approaches have also been studied. For example, Dart et al. (2000) found that students who adopted “qualitative” conceptions of learning, such as learning as seeking for in-depth understanding, tended to use deep approaches to learning. On the other hand, students who held “quantitative” conceptions of learning, such as memorizing, were likely to use surface approaches to learning.
Furthermore, Tsai's (2004) study revealed that students' learning outcomes and academic performance may be affected by numerous factors, and two of these factors, students' conceptions of learning and approaches to learning, are considered to be particularly important. Thus, in this study, we argue that for chemistry educators, it is important to investigate students' conceptions of learning and approaches to learning, particularly in chemistry. The purpose of the present research was therefore to identify Taiwanese college students' conceptions of and approaches to learning chemistry through a quantitative methodology. The relationships between the conceptions and approaches were also investigated. This study also aimed to examine the grade differences in students' conceptions of and approaches to learning chemistry.
The aforementioned studies were undertaken to investigate conceptions of learning in general. However, there have also been a number of studies particularly focused on science. For instance, Tsai (2004) in Taiwan interviewed 120 high school students and proposed a framework for the conceptions of learning science (COLS) consisting of seven categories: (1) learning science as memorizing, (2) learning science as preparing for tests, (3) learning science as calculating and practicing tutorial problems, (4) learning science as an increase of knowledge, (5) learning science as applying, (6) learning science as understanding, and (7) learning science as seeing in a new way. Tsai's (2004) and a number of following studies (Tsai et al., 2011; Lin et al., 2012b) also suggested that these conceptions could be viewed as having a hierarchical order, from lower-level to higher-level where the first three, “Memorizing,” “Testing,” and “Calculating and Practicing,” can be viewed as the lower-level conceptions, while the others are the higher-level conceptions, including “Increase of knowledge,” “Applying,” “Understanding,” and “Seeing in a new way.”
According to Chiou et al. (2012), to gain a deeper understanding of how students learn in various scientific domains, future research should move forward to explore conceptions of learning in more specific domains. Chemistry is one of the important domains in science. Hence, in this study, we intended to investigate college students' conceptions of learning chemistry (COLC).
According to Yang and Tsai (2010), approaches to learning have been extensively investigated in various domains and for different academic tasks. For example, approaches to problem solving in engineering (Marshall et al., 1999), approaches to learning pharmacy (Smith et al., 2010), approaches to learning through discussion (Ellis et al., 2008), and approaches to learning mathematics (Cano and Berben, 2009) have all been studied. Specifically in science, research has been undertaken on approaches to learning biology by Chiou et al. (2012).
The essence of the deep and surface approaches to learning varies widely across different domains (Ramsden, 1992). For example, in mathematics, the surface approaches to learning may refer to the processes of repeatedly calculating and following an algorithm, while in biology, they may refer to the processes of matching the name of a specific species with its distinct features. Although some researchers in the field of science education have started to tackle this issue (e.g., Lee et al., 2008; Liang and Tsai, 2010), most of them have concentrated only on students' approaches to learning in a broad content domain, such as science. Given the nature of different domains in the field of science, such as physics, chemistry and biology (Tsai, 2006), there would be merit in exploring students' approaches to learning in the different scientific domains. Based on this premise, this research planned to focus specifically on students' approaches to learning chemistry (ALC).
Kember et al. (2004) claimed that students might perform differently in each learning domain. Students may use deep approaches to learning science but use surface approaches to learning in other domains. Tsai (2004) also suggested that conceptions of learning are domain specific.
Therefore, it has become an important issue for science educators to investigate the interplay between students' conceptions of learning science and their approaches to learning science (e.g., Chin and Brown, 2000; Tsai, 2004; Tsai and Kuo, 2008). However, few studies have addressed this interplay, particularly in the specific area of learning chemistry.
This research, by using a stepwise regression model, was conducted to explore the relationships between college chemistry-major students' conceptions of learning chemistry and their approaches to learning chemistry.
First, using exploratory factor analysis to examine chemistry-major students' COLC and ALC questionnaire items, this study was undertaken to investigate the following questions:
(1) Do the chemistry-major students display grade differences in their COLC and ALC?
(2) Are the chemistry-major students' COLC related to their ALC?
(3) Can the chemistry-major students' COLC predict their ALC by stepwise regression models?
All of the students were chemistry-related majors and had taken a series of chemistry-related courses before participating in this study. Their ages ranged from 18 to 25, with an average age of 20.2; 152 were lower grade (freshman and sophomore) students (41.2%), and 217 were higher grade (junior and senior) students (58.8%).
To develop the questionnaire about conceptions of learning chemistry, two experts in science education and chemistry examined the content of all the questionnaire items, providing expert validity for the survey. Following the procedure above, the questionnaire was slightly modified. The six factors in the final COLC are described below, with a sample item provided:
1. Memorizing: learning chemistry through memorizing definitions, formulae, laws, regulations and special terms.
˙ Item: when learning chemistry, I usually memorize the special terms found in the chemistry textbook that can help me to answer the teacher's questions.
2. Testing: learning chemistry is conceptualized to get higher scores to pass the chemistry exam.
˙ Item: if there were no exams, I would not learn chemistry.
3. Calculating and practising: learning chemistry means calculating, practising tutorials and manipulation of formulae and numbers.
˙ Item: to learn chemistry well, I need to do a series of calculations and practise answering questions.
4. Increasing one's knowledge: learning chemistry is viewed as increasing chemistry knowledge for the learner.
˙ Item: learning chemistry means acquiring knowledge that I did not know before.
5. Application: the application of receiving the chemistry knowledge is considered the main feature of learning chemistry.
˙ Item: learning chemistry is to acquire some knowledge and skills to solve real-life problems.
6. Understanding and seeing in a new way: learning chemistry is conceptualized as achieving true understanding and getting a new perspective.
˙ Item: learning chemistry means understanding more natural phenomena and knowledge.
˙ Item: learning chemistry means using a new way to view chemical phenomena or topics related to chemistry.
These factors represent students' COLC in a hierarchical framework. The first three factors are lower-level while the others are higher-level (Liang and Tsai, 2010).
The second questionnaire, ALC, was based on another questionnaire named “Approaches to Learning Science” (ALS) with four factors developed by Lee et al. (2008).
It was designed for Taiwanese high school students, and Liang et al. (2010) modified it to survey university science-major students, a similar target sample to this study. Again, two experts in science education and chemistry revised the content of all the questionnaire items. Based on the above procedure, the questionnaire was modified to fit the needs of this study. These four factors in the final ALC are described below:
1. Deep motive: this factor concerns whether the student has more intrinsic motive (e.g., feeling happy and satisfied) for learning chemistry.
˙ Item: I always feel interested in learning chemistry.
2. Deep strategy: this factor refers to the student using deep strategies (e.g., exploring the relationships between science concepts or other ideas) to learn chemistry.
˙ Item: when I learn new contexts about chemistry, I am trying to explore the relationships with other contexts I learned before.
3. Surface motive: this factor concerns the student's extrinsic motive (e.g., fear of failure or someone's expectations) for learning chemistry.
˙ Item: although I prepared well for the chemistry exam, I still fear I could not get a great score.
4. Surface strategy: this factor refers to the degree to which the student uses surface strategies (e.g., narrow target, rote learning) to learn chemistry.
˙ Item: I find the best way to get high scores in chemistry exams is to remember the answers to likely questions.
All of the items in the two questionnaires were presented with a 1–7 Likert scale, from “strongly disagree” to “strongly agree.”
Utilizing the 369 students' responses to the final-version questionnaires, further analyses were conducted to explore the relationships between their conceptions of and approaches to learning chemistry.
This research first used exploratory factor analysis to examine the factor structure of the COLC and the ALC questionnaires. The correlations within and between the COLC and ALC factors were analyzed. Then, to examine the lower grade and higher grade students' differences in the COLC and ALC, t-tests were conducted. Finally, the regression analyses between the factors of the COLC and those of the ALC were analyzed. The COLC factors were considered as predictor variables, whereas the ALC factors were processed as outcome variables.
As shown in Table 1, the KMO values are 0.95 and 0.92 for the COLC and the ALC questionnaire respectively, and the skewness and kurtosis values for each item of both questionnaires are also shown to fall within acceptable ranges, indicating a normal distribution. This means that these two questionnaire items are quite suitable for further factor analysis.

There are statistically significant positive correlations between “Memorizing,” and “Transforming” of the COLC and two factors of the ALC, “Deep Motive” (r = 0.26 and 0.58, p < 0.001), and “Deep Strategy” (r = 0.23 and 0.80, p < 0.001), and negative correlation was identified between “Testing” and two deep approach factors (r = −0.30 and −0.24, p < 0.001 for “Deep Motive” and “Deep Strategy” respectively).
This positive relationship between the lower-level COLC, “Memorizing” and the deep approaches deserves more discussion, as it contradicts a common result regarding the negative relationship between lower-level conceptions of learning and deep strategies of learning (e.g., Zeegers, 2001; Lee et al., 2008; Chiou et al., 2012). Chemical representations, such as formulae, symbols, equations, and structures, are widely seen in professional journals and routinely used to describe and explain chemical reactions and phenomena in textbooks (Black and Deci, 2000). Because of this feature of chemistry, no matter how much experience students accumulate or how they meaningfully process the chemistry learning tasks, they still have to use a certain degree of memorization to learn chemistry.
Moreover, positive associations were found between “Memorizing,” and “Transforming” of the COLC and the factor of the ALC, “Surface Motive” (r = 0.37 and 0.78, p < 0.001). The correlation between “Memorizing,” “Testing,” and “Calculating and Practicing,” of the COLC and the ALC factor, “Surface Strategy,” are statistically positive, with coefficients ranging from 0.31 to 0.44 (p < 0.001).
It is interesting that both “Memorizing” and “Transforming” have positive relationships with “Surface Motive.” Most Western researchers seem to believe that many South-East Asian learners display a special feature of learning, that is, memorizing with understanding, and this may be rooted in an orthodox philosophy, namely the Confucian heritage (Au and Entwistle, 1999). Besides, Hong and Peng (2008) have revealed that Chinese students will work hard for good scores on exams, no matter what motivational and metacognitive strategies they are using. Furthermore, Tsai (2004) has asserted that students' learning is associated with the exam-driven sociocultural environment in Taiwan, where standard test scores and nationwide examinations are highly emphasized by parents and teachers across different levels of education. When facing these exams, they need to rely on the memorization of some chemistry knowledge, but at the same time, a good transformation of instructional materials into meaningful representations is also necessary. That is, even though students simply want to get good grades in chemistry exams, they may still possess higher-level conceptions of learning chemistry, such as applying chemistry knowledge to problem-solving. This may explain why students' “Memorizing” and “Transforming” have positive correlations with the “Surface Motive” approach to learning chemistry at the same time.
Table 5 shows the lower grade and the higher grade students' mean scores for the factors in the COLC and the ALC. The t-test results indicated that higher grade students had a higher “Transforming” score (t = −3.43, p < 0.01) than the lower grade students in COLC. After examining the grade differences by t-test, effect sizes were also calculated to examine the significance of factor-score differences between the lower and higher grade students. The effect size for t-test is often described as a Cohen's d value (Cohen, 1998), where d = 0.2 is considered as a small effect size, while d = 0.5 is deemed as a medium effect size, and d = 0.8 is a large effect size. The results presented in Table 5 show that the differences between the two groups (lower and higher grade students) were not only statistically significant, but the effect of the size of the ‘Transforming’ score (d = −0.36) shows that the difference was, to some extent, still substantial in this study, at least a small to medium effect size. Besides the “Transformation” factor, other COLC factors did not show any statistical difference between the two different grades (“Memorizing,” t = −0.40, p > 0.05, d = −0.04; “Testing,” t = 0.30, p > 0.05, d = 0.03; “Calculating and practicing,” t = −0.76, p > 0.05, d = −0.08).

This result reveals that the higher grade students tend to have more high-level COLC than the lower grade students. The higher grade students spent more time on learning the chemistry knowledge and accumulated more experience in chemistry than the lower grade students. It is plausible that the higher grade students would tend to apply chemistry knowledge in daily life, and make more radical changes when conceptualizing learning chemistry.
Moreover, higher grade students also had significantly higher scores for two ALC factors, “Deep Strategy” (t = −2.96, p < 0.01, d = −0.31) and “Surface Motive” (t = −3.91, p < 0.001, d = −0.41) with small to medium effect sizes, than those in the lower grades. There was no significant difference shown between the lower grade and the higher grade students' scores on the “Deep Motive” (t = −1.53, p > 0.05, d = −0.16) and the “Surface strategy” (t = −0.23, p > 0.05, d = −0.02) factors.
This result is consistent with the finding confirmed in Zeegers' (2001) study that more experienced students tend to use deep strategies to process their learning tasks in science. Nevertheless, according to Tsai (1998), there are more job opportunities for students with a major in science than for other majors in Taiwan. Therefore, students in the later stage of undergraduate study may be gradually led to the motive of learning science as a means of obtaining a better economic situation in life. This may go some way to explaining the higher-grade students' surface motive for learning chemistry.
Table 6 shows the regression analysis results. The COLC factors, “Transforming,” “Testing,” and “Memorizing,” could make significant predictions for the students' ALC factor, “Deep Motive.” “Transforming” and “Memorizing” made positive predictions (t = 9.88 and t = 3.93, p < 0.001), while “Testing” could negatively explain “Deep Motive” (t = −5.11, p < 0.001). “Transforming” (t = 23.88, p < 0.001) was the only predictor to explain the “Deep Strategy” of the ALC, and was a powerful predicting factor (R2 = 0.64).

That is, for the deep approaches to learning chemistry, the COLC factor, “Transforming,” likely plays a dominant role. This result suggests that the higher-level conceptions of learning chemistry constitute the foundation for all the students' deep approaches to learning chemistry.
Moreover, the lower-level conception of learning chemistry, “Testing,” is a negative predictor of “Deep Motive” to learn chemistry, a result similar to those concluded by the aforementioned research (e.g., Lee et al., 2008; Edmunds and Richardson, 2009; Chiou et al., 2012). However, it was interesting to find that “Memorizing” could positively predict “Deep Motive” to learn chemistry; that is, because of the features of chemistry, such as numerous formulae, equations or symbols for explaining chemical reactions, memorizing always plays an important role, no matter which motivation students hold in learning chemistry.
For the ALC factor “Surface Motive,” both COLC factors “Transforming” and “Memorizing” were significantly positive predictors (t = 20.59 and t = 4.65, p < 0.001) with high explained variation (R2 = 0.62). Finally, two COLC factors, “Testing” and “Memorizing,” could positively explain students' responses for the “Surface Strategy” factor (t = 7.13, p < 0.001 and t = 3.43, p < 0.01).
According to the results, for the surface approaches to learning chemistry, first, “Memorizing” is a main factor to predict surface approaches. Second, another COLC, “Testing,” was also a positive predictor of “Surface Strategy” of learning chemistry. These conclusions are also in line with the aforementioned past research on learning science (e.g., Lee et al., 2008; Tsai and Kuo, 2008; Chiou et al., 2012).
However, it was surprising to find that the higher-level conceptions of learning chemistry, “Transforming,” could be a positive predictor of “Surface Motive”; that is, as the students who have the higher-level COLC tend to adopt the surface motive to learn chemistry, they might study chemistry just to fulfill a course requirement and want to have great performance so as to get ideal jobs in the future.
To sum up, the regression results suggest that these college chemistry-major students' COLC play an important role in their ALC. In general, students who held lower-level COLC, such as “Memorizing” and “Testing,” tended to use surface approaches to learn chemistry; however, their surface motive can also be positively predicted by the higher-level COLC, “Transforming.”
At the same time, the students who have the higher-level conceptions of learning chemistry tend to adopt deep strategies and deep motives for learning chemistry, and they might view learning chemistry as arousing their intrinsic interest. It should be noted that “Transforming” can explain a large extent of the variation in the deep approach factors, especially for “Deep Strategy.” To possess higher-level COLC is quite important for the potential utilization of deep strategies. But surprisingly, “Memorizing” is also a positive predictor of possessing deep motive to learn chemistry.
According to the curriculum design for the department of chemistry in Taiwan, the core ability for students is not only to understand the theoretical chemistry knowledge but also to apply the theories to the experimental operations or more real-life problems. Undergraduate chemistry majors may have to increase their knowledge and then transform the knowledge in practical applications or in explaining chemistry phenomena. That is, for chemistry-major college students, their higher-level conceptions of learning chemistry may occur at the same time.
Moreover, as shown in Table 2, while the students scored higher on the first three factors, “Memorizing,” “Testing,” and “Calculating and practising,” they scored lowest on the final factor, “Transforming.” This result reveals that the students prefer to view learning chemistry from a lower-level rather than a higher-level perspective. However, the research by Chiou et al. (2012) has indicated that undergraduate biology-major students prefer to view learning biology from a higher-level rather than a lower-level perspective. Each domain in science has different features, which might influence students' conceptions of learning and approaches to learning. Undergraduate chemistry educators in Taiwan may modify the curricula to help students focus more on the transformation of learning chemistry such as learning for in-depth understanding or new perspectives of thinking, rather than simply focusing on preparing for tests or calculations.
In terms of the practical implications, the two questionnaires developed in this study have high reliability. Chemistry educators could therefore use these questionnaires to explore undergraduate students' conceptions of and approaches to learning chemistry. Also, more attempts should be made to foster students' conceptions of learning chemistry. For example, chemistry teachers may highlight the idea that there are other things more important than getting good grades in examinations, such as expanding their knowledge and experience, and applying chemistry knowledge to solve problems in daily life.
This study used quantitative measures to explore college chemistry-major students' conceptions of learning chemistry and approaches to learning chemistry. More in-depth qualitative research is recommended to further explore these issues.
2. When learning chemistry, I usually memorize the important concepts found in the chemistry textbook.
3. When learning chemistry, I usually memorize the proper nouns found in the chemistry textbook as that can help me to answer the teacher's questions.
4. When learning chemistry, I usually remember what the teacher talked about in chemistry class.
5. When learning chemistry, I usually memorize chemistry symbols, chemistry concepts, and facts.
