This study aimed to adapt a new version of the Science Motivation Questionnaire II, the Chinese Chemistry Motivation Questionnaire II, for high school students in China, focusing specifically on chemistry. The sample consisted of 1635 students from four high schools, by stratified random sampling. Data was collected online. Exploratory and confirmatory factor analysis confirmed the original five-component motivation (intrinsic motivation, career motivation, self-determination, self-efficacy and grade motivation) structure after dropping four problematical items, and the factorial invariance was also confirmed across gender, region of residence, and choice of chemistry. Five components were strongly correlated in the Chinese context. Among the five components, students scored the highest in grade motivation. Generally, students who would continue chemistry scored much higher in all five components than those who would discontinue, with boys scoring slightly higher than girls and urban students scoring slightly higher than rural students. Specifically, for students who would continue chemistry, there were medium gender differences in self-efficacy, small gender differences in intrinsic motivation, career motivation, and self-determination, no significant gender differences in grade motivation, and small regional differences in all five components. For students who would discontinue chemistry, there were no significant differences in all five components across gender and region of residence. The internal structure of the questionnaire, correlations among the five components, and group differences in motivation were discussed. Some implications for researchers and practitioners were presented.
Fewer students are now selecting chemistry because the subject is optional in Chinese high schools. For example, in Zhejiang province, the percentage of students studying chemistry declined from 65% in 2014 to 51% in 2017. The extent of the decrease varies across Chinese provinces along with the pace of reform. A similar phenomenon has been reported in other countries where students lack the desire to study science and pursue science-related careers (Dekkers and de Laeter, 2001; Osborne et al., 2003; Lyons, 2006; DeWitt et al., 2014).
Motivation is an important factor influencing high school students’ course selection. High school students motivated to study chemistry are more likely to aspire to chemistry-related advanced courses and majors in the future (Bryan et al., 2011; Ardura and Perez-Bitrian, 2018). The Science Motivation Questionnaire II (SMQII, Glynn et al., 2011) is widely used in college and secondary schools to measure students’ motivation to learn science. It can also be used for specific domains (e.g., math, physics, chemistry, and biology) and adapted for use across languages and cultures.
The purpose of the present study was adaptation of the SMQII for Chinese high school students. In Chinese high schools, there is no subject termed ‘science’ but chemistry, physics, and biology are specific scientific disciplines that students can study. Students who choose chemistry may select other science subjects—or not—but their selection of chemistry will impact their selection of chemistry-related majors in college. Therefore, it is reasonable to measure students’ motivation to study chemistry specifically rather than measuring their general motivation to learn science.
Social-cognitive theory, developed by Bandura (1986, 2001, 2005, 2006) and extended by others (Pajares, 1996; Schunk, 1999, 2001; Schunk and DiBenedetto, 2020; Woolfolk, 2020), posits that human functioning involves triadic reciprocal causality among behavioral, environmental, and personal factors. Motivation, as a personal factor (Schunk and DiBenedetto, 2020; Woolfolk, 2020), depends on other personal, environmental, and behavioral factors (e.g., gender, socioeconomic status, and level of ability), and changes as individuals mature (Schunk et al., 2014). Differences in motivation, thus, in turn, reflect individual, group, social, and cultural differences (Schunk et al., 2014).
The motivation to learn chemistry may be different in high school between students who aspirate chemistry as a subject and those non-aspirates. Students who chose chemistry are typically more motivated to learn the subject than those who do not chose it (Bryan et al., 2011; Palmer et al., 2017; Ardura and Perez-Bitrian, 2018). The effect size may vary depending on the components. The largest one may be career motivation (Ardura and Perez-Bitrian, 2018). However, other researchers found large difference in intrinsic motivation (Lyons, 2006; Sadler et al., 2012; Lent et al., 2018), or self-efficacy (Brown and Cinamon, 2015; Avargil et al., 2020; Shwartz et al., 2021).
The motivation to learn chemistry may be different across gender. In high school, boys tend to have more positive beliefs about science than girls (Meece and Jones, 1996; DeBaker and Nelson, 2000; Meece et al., 2006; Brotman and Moore, 2008; Sunny et al., 2017), though girls reported higher scores than boys in some components for chemistry, such as self-determination (Salta and Koulougliotis, 2015; Ardura and Perez-Bitrian, 2018).
The motivation to learn chemistry may also vary depending on the regions where students live. In China, the culture and socioeconomic status of rural and urban residents can be very different (Murphy and Johnson, 2009; Hao et al., 2014; Wu, 2019). Rural residents engage in agricultural work, while urban residents undertake industrial and commercial work. Generally, people earn more money in industry and business than in agriculture. From the perspective of social-cognitive theory, these differences in culture and socioeconomic status (environmental factors) may influence the motivation (personal factor) of students coming from particular areas. A study about learning English as a foreign language with Chinese students showed the regional difference (higher for urban students).
The construct of five components is based on social-cognitive theory and the findings of earlier studies. Science education researchers have created many motivation constructs and adopted four theoretical orientations: behavioral, cognitive, humanistic, and social. Noteworthy constructs include arousal and anxiety, interest and curiosity, intrinsic and extrinsic motivation, self-determination, goal-directed behavior, self-regulation, self-efficacy, expectations, and strategies (Koballa Jr and Glynn, 2007). Integration of these constructs within the social-cognitive framework gave rise to six key components: intrinsic motivation, extrinsic motivation, personal relevance (student goals), self-determination, self-efficacy, and assessment anxiety. The Science Motivation Questionnaire (SMQ)—the first edition of the questionnaire—was developed to assess these six components (Glynn and Koballa Jr, 2006).
The SMQII—the second edition of the questionnaire—was based on the results of studies using SMQ to assess students’ motivation to learn science. Assessment of non-science major students’ motivation to learn science using SMQ revealed that (1) intrinsic motivation involved personal relevance, and self-efficacy was linked to assessment anxiety, and (2) extrinsic motivation differentiated between grade and career motivation (Glynn et al., 2007, 2009). SMQII was developed by revising the SMQ to assess the five components identified.
The SMQII has also been translated into several languages. In a cross-cultural study, Zeyer et al. (2013) translated the SMQ for upper secondary students in four countries: Malaysia, Slovenia, Switzerland, and Turkey. Schumm and Bogner (2016) translated the SMQII into German for tenth graders at the college preparatory secondary school level, and Shin et al. (2018) translated the SMQII for male Korean high school students. The SMQII was also translated for Chinese high school students by Dong et al. (2020).
Several researchers have adapted the SMQII by replacing ‘science’ with specific disciplines and then translating the tool into their own languages. Ardura and Perez-Bitrian (2018) focused on physics and chemistry and translated the questionnaire into Spanish for use with secondary school students. Salta and Koulougliotis (2015) and de Souza et al. (2022) opted for ‘chemistry,’ and translations into Greek and Brazilian for secondary school students, respectively. Janstova and Sorgo (2019) used the word ‘biology,’ and translated the questionnaire for Czech upper secondary school students.
There is, however, one point of concern. Komperda et al. (2020) tested a modified SMQII with wording variants (‘science’, ‘chemistry’, or ‘biology’) and extension revisions in problematic items found in previous studies, and found that none of the individual scales demonstrated acceptable functioning across all course and wording conditions, although data-model fit for the five-factor structural model was acceptable.
The SMQII was originally developed in English to measure college students’ motivation to learn science. Adaptation was needed to ensure the instrument was suitable for our study, measuring Chinese high school students’ motivation to learn chemistry. Three variables were considered in the process of adaptation and translation: language (English and Chinese), discipline (science and chemistry), and grade (college and high school). When translating, we attempted to conform to the actual situation of chemistry learning in Chinese high schools and use Chinese language appropriate for this context (Gregoire, 2018).
This study also investigated factorial invariance of the CCMQII across groups of interest. Chinese high school students’ motivation to learn chemistry may vary with gender, region of residence, and choice of chemistry. Therefore, we evaluated whether the components of the CCMQII were invariant across groups: gender (boys or girls), region of residence (urban or rural), and choice of chemistry (choosing or abandoning the subject). Factorial invariance would suggest that the CCMQII can be widely used (Byrne, 2016).
Thus, the goal of the study was to adapt the SMQII to measure Chinese high school students’ motivation to learn chemistry. A related goal was to test the factorial invariance across gender, region of residence, and choice of chemistry. The following research questions were associated with these goals:
(1) What is the construct validity (internal structure) and reliability (internal consistency) of the CCMQII in high school students?
(2) Is the CCMQII factorial invariant across groups by gender, region of residence, and choice of chemistry in terms of model-fit-index differences?
(3) What are the similarities and differences in students’ motivation to learn chemistry across groups by gender, region of residence, and choice of chemistry?
The present study translated and adapted SMQII to a specific discipline-chemistry. Small changes to item wording could affect instrument functioning (Komperda et al., 2018a). Science is not equivalent to, or includes, chemistry, and the motivation to learn science is not the same as the motivation to learn chemistry. The adaptation of SMQII needs to be first adapted to the practical context of chemistry education.
A broad student body was considered. China has a large number of high school students, and students have different levels of learning. Only one school could not represent the total efficiently. It makes more sense to select students from multiple levels.
After checking the validity and reliability of the CCMQII, an ex-post-facto design was used to investigate group differences across the five motivational components of the three groups: choice of chemistry, gender, and region of residence.
The students lived in different regions: 927 (57%) in urban locations (city and county) and 708 (43%) in rural (town and village) settings. In School A, there were 479 urban students and 65 rural students. School B had 226 urban students and 188 rural students. In School C, there were 144 urban students and 248 rural students. School D comprised 78 urban students and 207 rural students.
The students could either choose or abandon chemistry in the second semester of tenth grade. In total, 1100 (67%) students chose chemistry, and 535 (33%) students opted to abandon it. In School A, 451 students chose chemistry and 93 students abandoned it. In School B, 265 students chose chemistry, and 149 students abandoned it. In School C, 202 students chose chemistry and 190 students abandoned it. In School D, 182 students opted to continue with chemistry while 103 decided not to.
The students had previously taken a 1 year chemistry course in ninth grade. In accordance with the Chinese curriculum, ninth graders start taking chemistry courses and the score for that course is used for high school entrance exams.
The three translators worked on their translations independently, seeking a balance between accurate/equivalent words in the translations and culturally appropriate language. To facilitate the understanding of meaning, the three translators met before translation to clarify the definitions and indicators of the concepts in the questionnaire. After that, the first and second translators performed an independent translation, focusing on the meaning of the items rather than on literal word-for-word translation. After individual translations, the three translators met to identify and discuss any discrepancies and decide on the most appropriate translations.
The final version was the CCMQII (see Appendix A). Compared to the original version developed by Glynn et al. (2011), the CCMQII used more native expressions, for example, ‘grade’ was translated into ‘score’ because in Chinese high schools scores are usually used but not grade. Compared to the version translated in the study performed by Dong et al. (2020), the CCMQII used simpler expressions for easy understanding to students. Two expressions confused us, one was ‘think about’, and the other was ‘give me a career advantage’. Our translation team ended up giving different translations based on the original meanings.
An online questionnaire was developed for ease of data collection. The questionnaire included three pages. The first page contained three demographic items: gender, age, and region of residence. Page 2 contained the 25 items of the CCMQII. Students could respond to each item on a rating scale of temporal frequency: never (0), rarely (1), sometimes (2), often (3), or always (4). The final page required participants to indicate their choice of chemistry for the future. Participants could complete the questionnaire online or using their mobile phones.
Next, factor analysis was performed and the internal structure of the CCMQII was tested. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were used for a new setting (Lewis, 2022). To use cross-validation, the 1635 students in the sample were randomly split into two samples for CFA (n = 817) and EFA (n = 818). EFA was performed using the software jamovi to identify the underlying factors in the 25 items by clustering them into a smaller number of homogeneous sets, each of which constituted a new factor. Factors were extracted via principal axis method based on parallel analysis, followed by direct oblique rotations (Costello and Osborne, 2005). CFA was used because the CCMQII was based on a hypothesized five-factors structure underpinning the motivation to learn science in the SMQII. Since the students in our investigation were supposed to be distinct regarding their motivation to learn chemistry, we also undertook the CFA separately in the total sample and six subgroups: boys, girls, urban, rural, choose, and abandon.
Furthermore, factorial invariance testing was used to examine if the internal structure was consistent across groups of interest: choice of chemistry, gender, and region of residence. We analyzed the model-fit indices, factor loadings, and correlations of the five components using the Analysis of Moment Structure (AMOS, version 24, IBM) with the Maximum Likelihood (ML) method. More details of CFA and factorial invariance testing will be shown below.
Finally, the motivation differences across groups of interest were analyzed. Motivation differences across choice of chemistry reflected the influence of motivation on students’ choice of chemistry, and motivation differences across gender and region of residence reflected the influence of gender and region of residence on motivation. We used a factor-based scale score, which is the mean value of the items within each factor. Using the software jamovi, mean differences in motivation were analyzed with independent samples t-tests. A Cohen's d was calculated to determine the effect size (Cohen, 1992), the value of d was interpreted as small (0.20), medium (0.50), or large (0.80).
The chi-square test is used to assess the extent that a proposed model varies from data and a non-significant p-value is ideal. However, the chi-square statistic depends heavily on sample size, and larger samples yield larger chi-square statistics meaning that the p-value is then always significant (Hoyle, 2012; Kline, 2016). To reduce the effect of sample size on the chi-square statistic, chi-square can be divided by the degrees of freedom (χ2/df). However, the same problem is still experienced to some extent and there is no universally agreed on standard of a good/bad fitting model (Hoyle, 2012; Kline, 2016). The GFI is used to calculate the proportion of variability in the sample covariance accounted for by the estimated covariance matrix. GFI is affected by sample size (Fan et al., 1999; Hoyle, 2012; Byrne, 2016) and the number of times that the true model is rejected (Type I error) increases substantially as the sample size increases (Sharma et al., 2005). For these reasons, we reported the chi-square values and the GFI values for comparison with other studies, but did not use them as indices of goodness of fit in the present study.
SRMR is sensitive to sample size but has little penalty for model complexity (Hoyle, 2012). That is, SRMR is positively biased, and that bias is greater for small sample sizes. RMSEA is also sensitive for small sample sizes, but not for large samples, and penalizes smaller models with relatively few variables (Hoyle, 2012; Kline, 2016). Thus, RMSEA is positively biased and the degree of bias depends on smallness of sample size and, especially, degrees of freedom. A 90% confidence interval can be computed for RMSEA and currently, RMSEA is one of the most popular measures of model fit.
CFI, TLI, and the non-normed Fit Index (NNFI) are all not sensitive for sample size and have a penalty for model complexity (Hoyle, 2012). CFI and TLI are not affected by sample size and penalize models that estimate many parameters. The difference between them is that the penalty of CFI for complexity is lower than for TLI (Kline, 2016), meaning that CFI is always greater than TLI.
The cut-offs (Glynn et al., 2011; Hoyle, 2012; Byrne, 2016; Kline, 2016; Schumacker and Lomax, 2016) suggest that CFI and TLI are goodness of fit indices, with values of 0.95 or higher indicating a good model fit. RMSEA and SRMR are badness-of-fit indices with RMSEA values of less than 0.08 indicating a good model fit, and SRMR values of 0.05 or less indicating good model fit.

In summary, across groups—gender, region of residence, and choice of chemistry—the model demonstrated factorial invariance (configural, metric, structural, and measurement residual invariance). The CCMQII can, thus, be used in broad populations.

Table 7 also shows the differences in motivation between students who would continue chemistry or not. The mean scores of the five components (intrinsic motivation, career motivation, self-determination, self-efficacy, and grade motivation) for the ‘Choose’ group were higher than those for the group ‘Abandon,’ and the differences were all statistically significant. Effect sizes were all very large.

Item Q1 was developed to measure intrinsic motivation, but low factor loading indicates poor quality in this study. This result is in line with some previous studies (Salta and Koulougliotis, 2015; Ardura and Perez-Bitrian, 2018; Dong et al., 2020; Komperda et al., 2020). Komperda et al. (2020) found students confused when facing ‘relevant’, and used the phrase ‘world around me’ instead of ‘life’ but still found low factor loading though improved. These results suggest that this item needs further investigation.
Item Q12 was also developed to measure intrinsic motivation, but its loading on career motivation is much greater than on intrinsic motivation in this study. This suggests that students respond to the item mostly as a reason to pursue a career. This result is similar to the result found by Komperda et al. (2020), and the later revised items using the phrase ‘world around me’ performed well in their study.
Item Q2 was developed to measure grade motivation, but with a slightly lower factor loading in this study This result is in line with some previous studies (Salta and Koulougliotis, 2015; Schumm and Bogner, 2016; Ardura and Perez-Bitrian, 2018; Dong et al., 2020; Komperda et al., 2020). Furthermore, this item also has a cross-loading on self-efficacy in this study, in line with the results found by Schumm and Bogner (2016). These results suggest that this item needs further investigation.
Item Q16 was developed to measure self-determination, but the factor loading was low and a cross-loading on self-efficacy was found in this study. Similarly, Komperda et al. (2020) also found the cross-loading of the item on self-efficacy. In contrast, some other studies (Schumm and Bogner, 2016; Schmid and Bogner, 2017; de Souza et al., 2022) had not found this cross-loading. These results suggest that this item needs further investigation.
Self-efficacy is strongly correlated with intrinsic motivation. This study found that the correlation coefficients between self-efficacy and intrinsic motivation were very large. This indicates that students who rated self-efficacy highly also rated intrinsic motivation highly. This result fits with most other studies (Bryan et al., 2011; Glynn et al., 2011; Salta and Koulougliotis, 2015; Ardura and Perez-Bitrian, 2018; Dong et al., 2020; de Souza et al., 2022), although the degree of correlation vary slightly.
The relationship between self-determination and intrinsic motivation should be further investigated. We found very large correlation coefficients between self-determination and intrinsic motivation. This indicates that This indicates that students who rated intrinsic motivation highly also rated self-determination highly. This result concurs with some studies (e.g., Bryan et al., 2011; Salta and Koulougliotis, 2015; Dong et al., 2020; de Souza et al., 2022), but differs from others (e.g., Glynn et al., 2011; Ardura and Perez-Bitrian, 2018). The mixed findings indicate a need for further research into the relationship between self-determination and intrinsic motivation.
The relationship between self-determination and self-efficacy needs to be researched further. Our study found a very large correlation between self-efficacy and self-determination, suggesting that students who rated self-efficacy highly also rated self-determination highly. This result is in line with some studies (e.g., Bryan et al., 2011; Dong et al., 2020; de Souza et al., 2022), but different to others (e.g., Glynn et al., 2011; Salta and Koulougliotis, 2015; Ardura and Perez-Bitrian, 2018). The inconsistent results suggest that further research into the relationship between self-determination and self-efficacy is also needed.
The differences are large in all five components (intrinsic motivation, career motivation, self-determination, self-efficacy, and grade motivation) between students choosing chemistry and those who will discontinue it in this study. These results were mostly in line with those found by some previous studies (Bryan et al., 2011; Ardura and Perez-Bitrian, 2018), except self-determination in which the effect size was just medium when they studied chemistry and science motivation in Spanish secondary schools and US high schools, respectively. These somewhat inconsistent results on differences in self-determination suggest the need for further research.
For students abandoning chemistry, there are no (or small) gender differences in five components. This study found no statistically significant gender difference, generally in line with those from Ardura and Perez-Bitrian (2018) who found small gender differences in career motivation and self-determination in Spanish secondary school students.
For students choosing chemistry, there are no (or small) gender differences in three components (intrinsic motivation, career motivation, and grade motivation), and mixed results in self-efficacy and self-determination. This study found no significant gender difference in grade motivation, a small gender difference in intrinsic motivation, career motivation, and self-determination, and a medium size gender difference in self-efficacy (higher for boys). Ardura and Perez-Bitrian (2018) found no significant gender difference in intrinsic motivation, career motivation, and self-efficacy, a small gender difference in grade motivation, and a medium size gender difference in self-determination (higher for girls) in Spanish secondary school students. Some researchers found similar results in samples with all students. Salta and Koulougliotis (2015) found no significant gender difference in four components (intrinsic motivation, career motivation, self-efficacy, and grade motivation), and a medium size gender difference in self-determination (higher for girls) in Greek secondary school students. de Souza et al. (2022) found no significant gender difference in intrinsic motivation, and a small gender difference in career motivation, self-determination, and grade motivation (all higher for girls), and self-efficacy (higher for boys) in Brazilian high school students. These results were generally consistent (no or small difference) for intrinsic motivation, career motivation, and grade motivation, but varied (no, small, or medium difference) for self-determination and self-efficacy.
Gender differences in self-determination and self-efficacy are also mixed in science motivation for high school students. For self-determination, this study found a small gender difference. Some studies observed similar results in Korean and China, respectively (Shin et al., 2017; Dong et al., 2020). However, Bryan et al. (2011) found no significant gender difference in students aspirating to continue science, and a small gender difference (higher for girls) in those who aspirate not to in US, and Schumm and Bogner (2016) found the opposite result—girls scored higher and a medium size gender effect was reported in German. For self-efficacy, this study found a medium size gender difference (higher for boys) in line with some studies in Korean and China (Shin et al., 2017; Dong et al., 2020). However, Schumm and Bogner (2016) found a small gender difference in German, and Bryan et al. (2011) reported none in aspirants and small gender difference in non-aspirants in US.
The gender difference in chemistry-related self-efficacy may be influenced by gender-role stereotypes for high school students (Steele, 1997; Meece et al., 2006; Sunny et al., 2017). In general, ‘boys report stronger ability and interest beliefs in mathematics and science, whereas girls have more confidence and interest in language arts and writing’ (Meece et al., 2006). From the perspective of social-cognitive theory, gender-role stereotypes are environmental factors and self-efficacy is a personal factor. Gender-role stereotyping could directly influence self-efficacy, and also indirectly affect it by mediation of behavioral factors (e.g., academic achievement and performance). The gender gaps in chemistry self-efficacy for high school students may be influenced by gender-role stereotyping of chemistry, and the opposite result (no gender gap) could be achieved by contending that girls can perform as well as boys (Else-Quest et al., 2013).
Differences in motivation to study chemistry between students living in urban and rural areas need to be taken more seriously. Differences in rural-urban areas are of particular concern in education and development in the People's Republic of China (Murphy and Johnson, 2009; Wang, 2012). Differences in student motivation to learn are one of the themes of this issue. The present study found no significant or small differences in student motivation to learn chemistry. To the best of our knowledge, for the first time, this study shows the results of no (or small) motivational differences between urban and rural high school students learning chemistry, using CCMQII and similar versions. It would be interesting to perform a comparison for nations and regions with regional difference.
For researchers, a factor analysis should be performed first when deciding on the use of these assessment instruments. Both exploratory and confirmatory factor analysis are encouraged, as only confirmatory factor analysis fails to find some problematic items, as happened in this study. If modification is decided to use, this and some previous studies compiled in this study would be carefully considered and some phrase revisions would be referred to the results investigated by some studies (e.g., Komperda et al., 2020).
For instructors deciding to use these instruments, a version of similar context (discipline and language, secondary school or college) should be preferred, and the problematic items should be dropped out. For example, in the Chinese context of measuring the motivation of high school students to study chemistry, CCMQII should be preferred when problematic items are dropped. Alternatively, collaboration with researchers should be encouraged to first confirm the validity of the instrument and, furthermore, to perform some possible additional modifications.
Instructors should pay special attention to grade motivation and intrinsic motivation, and step up efforts to fulfill student achievement needs and keep students interested and enjoying themselves in chemistry learning. To reduce the gender gap in motivation to learn chemistry, instructors should pay more attention to girls, especially in terms of self-efficacy in learning chemistry, and give girls more opportunities to be more successful and confident.
