This study aims to explore grade level and gender differences in the attitudes toward chemistry (ATC), self-efficacy (SE), and learning experiences (LE) of preservice chemistry teachers. A total of 191 pre-service chemistry teachers were taken as the sample through cluster random sampling technique. This crosssectional survey collected the data using CAEQ questionnaire and interview. MANOVA test was carried out to analyze the quantitative data on the significance level .05, while the qualitative data were analyzed using Patton qualitative data analysis procedure. The findings showed that: 1) the LE level of the preservice chemistry teachers was the highest compared to SE and ATC ; 2) there was a difference of ATC and SE between the freshman and sophomore groups, and there was a difference in terms of ATC between freshman and junior categories, yet no different in terms of LE based on this category; and that 3) there was no difference of ATC, SE, and LE based on gender. The results accord with the interview findings in which both male and female student teachers have positive attitudes toward learning chemistry, and there was a difference of ATC, SE, and LE between freshman, sophomore, and junior.

The 21st century learning system demands the use of technology in learning instruction. This research focuses on the comparison between the use of android-based-game and blended learning in the Chemistry subject on the hydrocarbon lesson toward students’ self-efficacy and achievement. A quasi-experiment with post-test only design was adopted in this research. A number of 143 eleventh graders from two public senior high schools in Purworejo Regency, Indonesia were selected in a cluster random sampling as the research sample. The sample was classified into three groups depending on the media used, i.e. android-based-game only on face-to-face learning (ABG-FTFL), blended learning only (BL), and both android-based-game and blended learning (ABG-BL). Self-Efficacy Scale (SES) was used to obtain the data of students’ self-efficacy while the hydrocarbon test was used to obtain students’ achievement. One-way Analysis of Variance, Kruskal Wallis test, and descriptive quantity technique were performed in the data analysis, and it is found that the use of these technologies has a significant effect on the students’ self-efficacy and achievement. The use of ABG-BL is better in improving students’ self-efficacy while BL is better in enhancing students’ achievement. Therefore, the use of android-based-game and blended learning can be emphasized as media in chemistry learning to gain better self-efficacy and achievement among students.

This quasi-experimental study used a pre-/posttest design to investigate student’s scientific habits of mind (SHOM) and chemical literacy. There were 32 students of the 11th grade selected for the experimental and control class. They were taken by random sampling. The experimental class applied inquiry learning via Predict-Observe-Explain-Extend (POEEd) using the socio-scientific issue (SSI) context, while the control class used a scientific approach that addressed the Indonesian national curriculum. The Acid-Base Chemical Literacy Test (A-BCLT) consisted of 19 items that used four contexts. Argumentative question added on each context. The other instrument was the SHOM scale in the SSI context. The scale consisted of 20 items in seven factors of SHOM. A group of experts looked at both instruments to ensure content validity. Then, the empirical test showed that both instruments have good reliability. MANOVA as the inferential statistic technique was used to analyze the differences among the group. The results showed that there was a significant difference in SHOM and students’ chemical literacy simultaneously. However, there was only a significant difference in students’ chemical literacy on separate analyses. Students have a better scientific argument in the case of acid rain as SSI, but it was less good for consumption of ulcer medicine for fasting people. Meanwhile, for SHOM, students have better thinking in open-mindedness and objectivity factors but less on curiosity. Some of the interesting findings and their implications are discussed in this study. The integration of SSI in chemistry learning is important. It is meaningful in promoting students’ thinking skills to become responsible citizens in the future.

Although chemistry-focused socio-scientific issues support the ‘relevance’ model of chemistry education, the related literature has lacked any systematic review handling them together. For this reason, this research aimed to thematically synthesize the research papers on chemistry-focused socio scientific issues (SSI) from 2008 to 2020 and inferentially evaluate them in terms of the relevance model of chemistry education. After searching international and national well-known databases through relevant keyword patterns (e.g., Pattern 1: socio-scientific issues and chemistry education), 65 research papers were apparent for the systematic review. Then, the authors generated primary and secondary codes for the research papers and then inferentially marked their ‘relevance’ components. The systematic review indicated variation of research areas (e.g., relevance model of chemistry education) and dominant research foci for different themes (e.g., competencies and related variables for the theme ‘aims’; pollution, energy, industry and fabrication-based problems for the theme ‘SSI’; organic compounds for the theme ‘chemistry concepts’). Further, it revealed that the research papers on chemistry-focused SSI had some shortcomings at handling all components of the relevance model in a balanced way. The current research suggests professionally training teachers about how to integrate chemistry-focused SSI and the relevance model into school chemistry.
