Abstract

Good learning outcomes are one of the benchmarks to determine the success of a learning process. All of this is caused by the lack of liveliness and curiosity of students during the Biology Science learning process. This study aims to: (1) Describe Biology Science learning on the digestive system material using a scientific approach through the cycle learning learning model, (2) Describe the increase in student learning outcomes on the digestive system material by using a scientific approach through the cycle learning learning model. This type of research is Classroom Action Research (CAR). The instruments used: (a) Student observation sheet, (b) Interview guide sheet, (c) Field notes, (d) Learning achievement test. The research subjects were class VIII-B students of SMP Negeri 1 Idanotae. Based on the results of the study it was found that there was an increase in student activity in the learning process, there was a sense of student responsibility in solving each problem given through worksheets, and students felt happy about learning with a scientific approach through the cycle learning model and there was an increase in student learning outcomes from 80% to cycle I to 90% in cycle II classically. Therefore, a scientific approach through cycle learning can be used as a good learning alternative to improve student learning outcomes on the digestive system material.

Abstract

This study aims to determine the increase in student learning outcomes through the discovery learning model at SMP Negeri 1 Idanotae in the 2022/2023 Academic Year. This research is a class action research (CAR). The instruments used: (a) Student observation sheet, (b) Interview guide sheet, (c) Field notes, (d) Learning achievement test. The research subjects were 31 class VIII-A students of SMP Negeri 1 Idanotae. Based on the results of research that has been carried out by researchers regarding improving the quality and learning outcomes of students through the discovery learning model, it can be concluded that the learning outcomes of students have increased from cycle I where there were 71% of students who completed classically and in cycle II all students classical finish. This increase was obtained because the discovery learning model can be student-centered, where students actively discover concepts on the human respiratory system for themselves. Based on the results of this study, researchers suggest that the discovery learning model can be used to improve student learning outcomes.

Abstract

The aim of the research is to determine the effect of the Decision Making learning model on students' cognitive learning outcomes. One solution to influence student learning outcomes, especially in the material on movement systems in plants, is through a Decision Making model that involves students directly, both individually and in groups, in learning activities. This research method is a quasi-experimental method which is quantitative, namely in the experimental class the Decision Making model is used, while in the control class the conventional method is used. The research results stated that in the control class the average learning outcomes on the pretest were sufficient and the average learning outcomes were good on the posttest. Meanwhile, in the experimental class by carrying out the pretest the average learning outcomes were sufficient and in the posttest the average learning outcomes were very good. The research conclusion based on hypothesis test calculations is that tcount is significantly greater than ttable. Because tcounts ttable, Ha is accepted and Ho is rejected, which means "there is an influence of the Decision Making learning model on student learning outcomes". The researcher's advice is for every Biology subject teacher to apply the Decision Making learning model in order to improve students' abilities, as well as improve teaching and learning methods and become reference material for future researchers who are relevant to this research.
