Self-efficacy (SE) can encourage students to complete their assignments. The research intended to investigate the achievement of students' self-efficacy by guiding concrete-pictorial-abstract (CPA) based on early mathematical ability (EMA). The research utilized quasi-experimental methods in learning mathematics regarding the volume of cubes and rectangular prisms. The population were all fifth-grade students of elementary schools in Purwakarta, Subang, Karawang, and Bekasi. Samples were 119 participants in Karawang. The instruments applied were questionnaires, tests, and daily journals. The prerequisite materials related to the volume of cubes and rectangular prisms are a topic about arithmetic calculation, square root, flat area, unit length, and problem-solving. Study’s result informed that there was no significant difference in the achievement of students' self-efficacy through CPA and conventional mentoring in the high and moderate EMA groups. There was a significant difference in the achievement of students' self-efficacy in the low group given CPA and conventional guidance. This finding gave birth to a strategy of developing self-efficacy in elementary schools using the CPA approach, especially the use of concrete objects around students through mentoring activities in schools, considering that self-efficacy makes it easy to solve problems especially when it comes to students with low initial abilities.

This study aimed to compare the students' motivation that learned by two different methods viewed from prior knowledge. This study used the quasi-experimental design. Data were obtained from motivation questionnaire which consist of 31 point statements. Data were analyzed using two ways ANOVA. The results showed that: (1) there was differences in students' motivation that learned with hands-on and demonstration in guided inquiry learning, (2) student with high prior knowledge have better motivation in learning rather than students with low prior knowledge, (3) there was no interaction between learning methods and prior knowledge on students' motivation. Penelitian ini bertujuan untuk mengetahui perbedaan motivasi belajar siswa yang dibelajarkan dengan 2 metode berbeda ditinjau dari kemampuan awal. Penelitian ini menggunakan rancangan eksperimen semu. Data penelitian diperoleh dari angket motivasi yang terdiri atas 31 butir pernyataan. Data dianalisis menggunakan ANOVA dua jalan. Hasil penelitian menunjukkan bahwa: (1) ada perbedaan motivasi belajar siswa yang dibelajarkan dengan praktikum dan demonstrasi dalam pembelajaran inkuiri terbimbing, (2) siswa dengan kemampuan awal tinggi memiliki motivasi belajar yang lebih baik dibandingkan siswa dengan kemampuan awal rendah, (3) tidak ada interaksi antara metode pembelajaran dan kemampuan awal terhadap motivasi belajar siswa.

This study aims to see and describe how the process of implementing lectures using the Discussion-Practice-Reflection technique improves the ability to improve basic teaching skills and the ability to develop learning tools with a scientific approach. The research approach used is quantitative and quasi-experimental methods with a research sample of 24 students (5th semester PAI course participants) by total sampling technic. Based on the data and descriptions of the division that has been carried out, it can be concluded that the DPR learning technique has a positive effect on the two variables tested, namely: basic teaching skills and the ability to develop learning tools in scientific approach. It can be seen from the results of the test that 50% of the students got “very good”, then 37.5% got “good” and 12.5% got “enough”. It can also be said that the use of DPR techniques in developing basic teaching skills was quite successful. Regarding the ability to develop learning tools, as many as 37.5% of students got “very good”, then 46% got “good” and 16.5% got a “enough”. It can also be said that the use of DPR techniques in developing learning tools skill with a scientific approach is quite successful.

This study aims to analyze the effectiveness of chemistry practicum skills on students’ problemsolving abilities. The method used is descriptive research with a survey approach. The sample was determined using a simple random sampling probability technique, which included chemistry teachers from three different schools and 107 students from three schools. Indicators of practicum skills to problem-solving abilities ie students complete learning. Survey data were analyzed using quantitative descriptive techniques. The results showed that 74 people (69%) were in the good category and 33 people (39%) were in the very good category, and there were no students in the average, poor, and failed categories. So, it can be concluded that students' practicum skills on the separation of mixture material are effective in problem-solving skills.

This study aims to analyze the effect of feedback from local content-based practicum modules on students' science process skills. Research subjects for product trials developed in this study were students of class XI using a purposive sampling technique with a sample size of 60 students. The method used in this research is quasi-experimental (quasi-experimental). The research instrument was a feedback rubric on applying a local content-based practicum module, observation sheets, and tests on the results of Science Process Skills (KPS). Data processing and analysis is carried out by comparing the initial and final science process skills scores by looking at the science process skills N-Gain score. Hypothesis testing uses the T-test to apply a local content-based practicum module on science process skills by analyzing the initial and final science process skills scores. The highest percentage result lies in the indicator of planning an experiment or investigation and using experimental tools and materials, namely 90%. There is a difference between a class that implements a local content-based practicum module and is given feedback with a class that uses a regular module for each class. The experimental class had an N-gain value of 0.75 or in the high category, while the control class had an N-gain value of 0.64 or in the moderate category. There are differences in students' Science Process Skills (KPS) using local content-based practicum modules with conventional practicum modules.

The Scientific Critical Thinking (SCT) model is a learning model developed to train critical thinking skills and student self-efficacy. This study aims to analyze the effect of the SCT model in improving critical thinking skills and the self-efficacy of Primary School Teacher Study Program students. This study used quasi-experimental research with the design of one group pre-test and post-test. The research subjects were one hundred and eight students of the Primary School Teacher Study Program from three classes of the Lambung Mangkurat University. Data was collected through tests of Critical Thinking Skills, questionnaires about student self-efficacy, and in-depth interviews. The collected data was analyzed using paired t-test / Wilcoxon test and n-gain. The results of the research on class D, class E, and class F indicate that the sig value is obtained. (2-tailed) critical thinking skills are 0.00 (p = <0.05) and n-gain is class D 0.77, class E 0.77 and class F 0.77 show that it is important in high criteria. In addition, sig is obtained. (2-tailed) student's self-efficacy is 0.00 (p = <0.05) and n-gain is class D 0.77, class E 0.81 and class F 0.79; shows significant results in high criteria. It was concluded that the SCT model was effective. This study implies that the SCT model can be used as an alternative to training students' critical thinking skills and self-efficacy.

This study aimed to produce and test the feasibility of a laboratory guidebook based green chemistry for high school students. The type of this research was research and development using the 4-D model. The laboratory guidebook produced was assessed by two lecturers and three chemistry teachers. Data collection techniques used were nontest techniques in the form of questionnaires. The data obtained are used to analyze the feasibility of the content, presentation, language, graphics, and applicability of the green chemistry concept to the laboratory guidebook that has been produced. Analysis of the results of the assessment showed that the laboratory guidebook based green chemistry was considered to be very feasible on four aspects namely content, presentation, language and graphics, and was judged to be feasible on the applied aspects of the green chemistry concept.
