Abstract

This research aims to determine the effect of using the guided inquiry learning model assisted by LKPD on creative thinking skills in acid-base solution material in class XI IPA students at SMAN 2 Pujut compared to using the conventional learning model. The method used in the research was a quasi-experiment with a pretest-posttest control group design. Sampling was carried out using cluster random sampling. The research sample consisted of class XI IPA 1 with 24 students as the experimental class and class XI IPA 2 with 24 students as the control class. The data in this research is creative thinking skills data collected using test techniques. The results of the data analysis showed that the average post-test score for the experimental group was 73.29 and the control group was 57.17. The t-test results show that the tcount is 1.93 > ttable 1.68 with a significance level of 5%. This shows that there is a positive and significant influence of the guided inquiry learning model assisted by LKPD on students' creative thinking skills.

Abstract

Problem-solving in chemistry requires support from various aspects, including psychological aspects such as self-efficacy and cognitive aspects such as creative thinking skills. This study aims to determine the effect of the Project-based Learning (PjBL) model on the self-efficacy and creative thinking skills of Grade XI students on the topic of buffer solutions at SMAN 1 Mauponggo. The research design used was a nonequivalent control group design, with purposive sampling as the sampling method, where participants were selected based on specific goals or criteria relevant to the research topic. The independent variable in this study was the Project-Based Learning (PjBL) model. Self-efficacy data were collected using a self-efficacy questionnaire. In contrast, creative thinking skills data were obtained through a test developed based on indicators of creative thinking skills (fluency, flexibility, originality, elaboration). Hypothesis testing was conducted using MANOVA. The results showed that both students' self-efficacy and creative thinking skills had an F-value of 15.198, which exceeded the F-table value of 4.05 at a significance level of 0.05. Based on these results, it can be concluded that the PjBL model has a significant effect on students’ self-efficacy and creative thinking skills.

Abstract

This study aims to find out what are the factors that cause online learning difficulties felt by students of SMA Negeri 1 Dompu. This type of research is a descriptive of qualitative research. The research population was 1006 students. The sampling technique was carried out using random sampling. Data collection uses a questionnaire that is empirically valid and reliable.. The technical analysis of the data used is descriptive statistics with percentages using Microsoft Excel. The results showed that online learning difficulties based on students' motivation factors were obtained 35%, students' learning interest factors were obtained 36%, students' family factors were obtained 43%, technical/network constraints factors were obtained 41% and students online learning implementation factors were obtained 42%. Based on the results of this study, it can be concluded that the factors causing online learning difficulties that are most felt by students in a row are family circumstances, the implementation of online learning, technical/network constraints, interest in learning, and finally learning motivation.

Abstract

This study aims to determine the differences in chemistry learning outcomes in blended learning using Edmodo media with Whatsapp class X students on electrolyte and nonelectrolyte solutions. This research is a Quasi Experimental Design research (quasi-experiment). The research design used in this study was a Quasi Experimental Design, namely the Non-Equivalent Control Group Design. Sample selection using purposive sampling technique. The research sample is experimental class I (X IPA 1) which applies blended learning using Edmodo media and experimental class II (X IPA 2) which applies blended learning using whatsapp media. The data collection technique used is a test instrument for understanding concepts (pretest and posttest) in the form of multiplechoice questions. Test the hypothesis in this study using the t-test. The results of the statistical test t-test tcount at a significant level of 5% shows tcount (2.43) > ttable (1,669) which means Ha is accepted and Ho is rejected. This shows that there is a significant difference in blended learning between using edmodo and whatsapp media in improving chemistry learning outcomes, where blended learning using Edmodo media is better in improving students' chemistry learning outcomes

Abstract

This study aims to develop a chemical problem-based learning module on petroleum material at SMAN 2 Mataram by using validity and practicality tests. The research model used is the 4D model, namely define, design, development, and dissemination. This study used a purposive sampling technique in sampling, involving 36 students of class XI MIPA 8 at SMAN 2 Mataram who were then used as respondents in a practicality test. Data analysis shows a good level of validity, with an Aiken V index of 0.88. Meanwhile, the practicality module was analyzed using the practicality index (student and teacher response questionnaire) so that the practicality module proportions were 86% (students) and 94% (teachers). These results provide evidence that the problem-based learning chemistry module on petroleum material is valid and practical. Therefore, this module can be applied in the learning process at SMAN 2 Mataram and maybe also in other schools that have a similar curriculum

Abstract

Pre-lab activities have not been a serious concern, especially in the development of instruments. Until now, pre-lab activities have only provided tests based on work procedures or concepts described in the practicum instructions. Instruments capable of measuring various aspects of basic laboratory skills have not been widely developed. This study aims to develop a pre-laboratory instrument based on basic laboratory skills. Five categories of basic skills were identified: procedural, manipulative, observation, interpretation, and conclusion skills. A total of 20 items, representing various aspects of the identified skills, were developed and deemed feasible through expert agreement. Testing the instrument on 45 respondents revealed that 15 questions met the criteria for validity (p<0.05) and demonstrated good reliability.

Abstract

This research is a type of Research and Development (R&D) with the 4D model (Define, Design, Develop, Disseminate) which aims to develop a description test instrumen to identify critical thinking skills of class XI students of SMAN 7 Mataram on chemical bonding material. The instrumen was developed by fulfilling the criteria of validity, reliability, level of difficulty, and distinguishing power. Validation was carried out by three experts, consisting of two Chemistry Education lecturers at Mataram University and one chemistry teacher at SMAN 7 Mataram. The results of content validity using Aiken's V with an average value of 0.82 which is classified as having a very high level of validity. Empirical validity states that all seven items are valid with the highest value reaching 0.83. The reliability test rcount of 0.813 is greater than the rtable indicates the item is reliable. The level of difficulty of the questions is in the medium category which ranges from 0.52-0.66. Differentiating power is in the sufficient to very good category ranging from 0.26-0.72. Students' critical thinking skills assessed using the developed instrumen were sufficient with an average value of 58.
