Abstract

This study investigated the effect of the Process Oriented Guided Inquiry Learning (POGIL) model on Grade 10 students’ chemical literacy in Green Chemistry topics using a quantitative experimental approach with an intact group comparison design. Two pre-existing classes were assigned as an experimental group taught using POGIL and a control group taught using Direct Instruction, with posttest-only assessment. The sample consisted of 59 Grade 10 students selected through purposive sampling (30 experimental, 29 control). A PISA-style chemical literacy test measuring content, context, and competency dimensions was used as the research instrument. Data were analyzed using descriptive statistics, tests of normality and homogeneity, and an independent samples t-test at a significance level of 0.05. The results showed that students taught using POGIL achieved a higher mean chemical literacy score (81.1) than those taught using Direct Instruction (70.1), with the difference being statistically significant (p 0.05). These findings demonstrate that the POGIL model has a positive effect on students’ chemical literacy in Green Chemistry contexts and supports its application as a literacy- and sustainability-oriented instructional approach.

Abstract

This study examined the effect of the STEM learning model on improving students’ cognitive learning outcomes in reaction rate topics using a quantitative experimental approach with a non-equivalent control group design. Two pre-existing classes were assigned as the experimental group (STEM) and the control group (Direct Instruction), both of which were given pretest and posttest assessments. The sample consisted of 70 Grade 11 students selected through purposive sampling, with 35 students in each group. The instrument used was a cognitive learning outcomes test measuring content, context, and cognitive competencies. Data were analyzed using descriptive statistics, normality testing, and the Mann–Whitney U Test at a significance level of 0.05. The results showed that the STEM group achieved a higher mean N-gain score (0.63) compared to the control group (0.38), with a statistically significant difference (p 0.05). These findings indicate that the STEM learning model has a positive and significant effect on improving students’ cognitive learning outcomes in reaction rate topics.

Abstract

Students often experience difficulties in understanding chemical concepts, which are generally abstract, such as chemical bonding material. The primary objective of the current research is to ascertain the specific impact resulting from the adoption of the Discovery Learning framework integrated with Javalab simulation of students' conceptual understanding as well as their interest in learning chemical bonding material within SMA Negeri 2 Sawang.  The investigative approach employed was a Pre-Experimental methodology that specifically adopted an Intact Group Comparison design structure. The entire population involved in this academic study comprised every student currently enrolled in class XI SMA Negeri 2 Sawang, with the sample determined by Saturated Sampling, consisting of class XI-1 as the treatment group and class XI-2 as the comparison group. The techniques utilized for the collection of necessary data included test instruments (posttest) to measure concept understanding and questionnaires to measure student motivation toward their studies. The purpose of analyzing used the Independent Sample T-test. The findings demonstrated that there was a meaningful impact existed from the Discovery Learning approach integrated with Javalab simulation on students' concept understanding (Sig. 2-tailed 0.002 0.05) and their educational curiosity (Sig. 2-tailed 0.000 0.05). The application of this model can visualize abstract concepts while simultaneously increasing the level of student involvement throughout the entire learning process.
