Abstract

Chemical concepts are not only taught abstractly by the teacher, but students also need to do it independently to better understand, of course, with the help of the teacher. So it is necessary to intervene in learning such as the right way in learning the right way. The purpose of this study was to demonstrate the effect of implementing a guided discovery learning model with the SETS approach with the help of a chemistry module on the scientific skills of SMA Negeri 1 Padang class XI students. The method of this study uses a quasi-experimental type of study, and the study design used is a randomized control group test-only design. The subject of this study is all students in class XI SMA Negeri 1 Padang, who are actively enrolled in 2021/202, which consists of seven classes. Groups of research populations are grouped using random sampling techniques. Multiple-choice test equipment/2-step literacy is based on up to 20 items. Technical analysis of data in this study is quantitative data analysis by testing hypotheses using the average analysis of the similarity test of 2 groups of unpaired samples (independent). The results of the hypothesis test, namely tcount> ttable, determined that the research hypothesis was accepted. This means that the implementation of a guided discovery learning model with the SETS approach supported by the Chemistry E module will have a significant impact on the scientific abilities of Class XI students in SMA Negeri 1 Padang

Abstract

This study aims to develop and analyze the validity of the developed e-module. This research is a type of educational design research using the Plomp model. At the validation stage, the feasibility of the e-module was assessed by three lecturers from the chemistry department, FMIPA UNP and two teachers from SMA Negeri 1 Lintau Buo. The validation results were obtained from experts consisting of three chemistry lecturers from FMIPA UNP and two chemistry teachers at SMA N 1 Lintau Buo. The research instrument used in this study was a validity questionnaire which was analyzed using the Aikens'V formula. The validation results were obtained from experts. The validation stage was carried out in two stages. The first stage obtained an average V value of 0.82 with an average content component validity with a V value of 0.75 (invalid), the linguistic component with a V value of 0. 88 (valid), the presentation component with a V value of 0.78 (invalid), the graphic component with a V value of 0.85 (valid) and the programming aspect with a V value of 0.84 (valid). The average validity obtained in the second validation stage is 0.86 (valid) with an average content component validity with a V value of 0.85 (valid), the linguistic component with a V value of 0.88 (valid), the presentation component with a V value of 0.88 (valid). V 0.83(valid), component with V value 0.85(valid) and programming aspect with V value 0.87(valid). After validation, the next step is a one to one evaluation test with a one to evaluation questionnaire instrument to three class XI students with different abilities. The conclusion from the research results is that the hydrocarbon e-module based on guided discovery learning for class XI SMA/MA which was developed is valid and can be continued for further research.

Abstract

Creative thinking skills can train and develop thinking processes in finding new ideas and ideas to solve chemical problems and problems through discovery, exploration, experimentation, showing and demonstrating similarities, differences, and consistency. Therefore, it is necessary to update what has been learned, such as choosing the right strategy. This study aims to demonstrate the effect of implementing a guided discovery learning model using a SETS approach supported by the chemical Young's modulus on the creative thinking skills of students in the SMAN 1 Padang XI class. The method used was a quasi-experimental study with a randomized control group posttest-only design. The population of this study is all SMAN 1 Padang Class XI students enrolled in the 2021/2022 academic year, which includes 7 classes. A study population is grouped using random sampling techniques. The non-testing tools used were the Student Profile Assessment Form and the Creativity Assessment Criteria. The data analysis technique in this study was quantitative data analysis, testing hypotheses by using two unpaired samples in the mean similarity test analysis tcount> ttable. The result of the hypothesis test indicates that the research hypothesis is accepted. This means that the implementation of the Guided Discovery Learning Model using the SETS approach supported by the Electrochemistry module has had a significant impact on the creative thinking skills of students in Class XI at SMA 1 Negeri Padang

Abstract

The purpose of this study is to analyze the influence of the application of guided discovery learning models based on lesson study for community learning on student learning outcomes. The type of research that pseudo-experiments use with research design is pretest-postest control group design. The population consists of students of class X MIPA at public high school 1 Padang. Sample selection is carried out by random sampling techniques, and selected sample classes, namely X MIPA 1 and X MIPA 4. The instrument used in this study is a test instrument in the form of multiple choice questions consisting of 20 questions with 5 answer options. Data analysis techniques use n-gain tests, normality tests, F tests and hypothesis tests (t tests). The average learning outcomes of students of the experiment and control classes were 81, and 72, respectively,.The level of influence of LSLC-based guided discovery learning models is analyzed through n-gain test scores. From the results of the study obtained an n-gain score in the experimental class of 0.74 with a high category while the control class was 0.61 with a medium category. At the significance level of 0.05 indicates the value of tcount (2.746) > ttable (1.995). So that the implementation of a guided discovery learning model based on lesson study for community learning has a problem with improving student learning outcomes
