Abstract

The aim of this study were to determine the differences of the  student's decision making skills before and after being taught using the STS (Science, Technology, and Society) learning model at MAN 3 Pontianak. The form of this research is pre-experimental design with the research plan of one group pretest-posttest design. The sample of this research is class X MIPA as an experimental class. The data collection tools used are the decision making skills test instrument and interview guidelines. Decision making skills were analyzed using the Wilcoxon test. The analysis is smaller than the significant level of 0.05 which means there are differences in decision making skills in class X MIPA MAN 3 Pontianak on scientific method sub-material before and after learning using STS ( Science, Technology, and Society) learning model. The n-gain calculation results obtained a value of 0.32, so the conclusions obtained that the STS (Science, Technology, and Society) learning model  affect student’s decision making skills in the medium category. Keyword : STS (Science, Technology, and Society) , Keterampilan Membuat Keputusan, Metode Ilmiah

Abstract

The aims of this research were to determine 1) the differences in student learning outcomes who taught using the webbed model with students who taught using conventional models 2) the influence of the webbed model with the theme of cigarettes was carried out in class VIII C and VIII D of SMP Negeri 24 Pontianak. The form of the research used was quasi-research with a non-equivalent control group design. The research sample was class VIII C as an experimental class and class VIII D as a control class. Data collection tools that was used in this study were tests. Based on the result of statistical test data using the Independent Sample T-Test, obtained a value of 0,000 indicates that the value of Asymp.Sig (2-tailed) < 0.05, which means there were significant differences in learning outcomes between the experimental class and the control class students. The effect of the webbed model on student learning outcomes after being analyzed with the effect size formula was 1.42 which means it provided an increase in learning outcomes of 42.22%. Based on the hypothesis test it can be concluded that learning with a webbed model can improve student learning outcomes.Keyword : Webbed Model, Learning Outcomes, Cigarettes

Abstract

The problem that arises in this study is that the assessment carried out by the teacher takes a relatively long time because of the manual calculation of points.  Then the teacher tends to make the same questions for all students, it makes it easier for students to collaborate. This study aims to determine the feasibility of an online evaluation tool using wondershare quizcreator on molecular shape materials. The form of this research is research and development (R&D) based on the steps of the ADDIE development model. The online evaluation tool using Wondershare Quizcreator on molecular shape material has been tested for feasibility by experts, including the feasibility of the material, language, and graphics. The expert feasibility test results show that the developed online evaluation tool is categorized as very feasible. This feasibility is viewed from the results of the validation of the feasibility of the material by 95.6%, the feasibility of language by 90.63%, and the feasibility of graphics by a percentage of 94.64%.

Abstract

The purpose of this research is to determine the difference of student learning interest and students learning outcomes with the influence of joyful learning strategies with ROCQ (Ranking One Chemistry Quiz) game on the results of student learning outcomes. This study employed a Quasi-Experimental Design with "Nonequivalent Control Group Design". The sample was class X MIA 5 as control class and class X MIA 3 as experimental class. Based on the result of data analysis in this research, it can be concluded that there were many differences in students learning interest and student learning outcomes which was significant between experimental class with control class after using joyful learning strategies with ROCQ game. This can be finded which the result of U-Mann Whitney test  questionnaire interest in learning (α ≤ 0,05) was obtained sig (2-tailed) of 0,000 and posttest (α ≤ 0,05) was obtained sig (2-tailed) of 0,000. The effect of learning used joyful learning strategies with ROCQ game was 49,45% to increase in class X students learning outcomes in element periodic system material in SMA Negeri 1 Sungai Raya. So, it means by using joyful learning strategies can give the positive influence to the students interest and learning outcomes.Keyword : Joyful Learning Strategies with ROCQ Game, Learning Interest, Learning Outcome
