Abstract

This research aims to determine the effect of the cooperative learning model with Baurus pattern problem solving method on the collaborative skills of students of SMP Kristen 2 (Christian Junior High School 2) on the subject of Indonesian Ecology and Biodiversity. The method used in this research is quantitative descriptive (quasi-experimental). The research subjects were students of class VII-D (control class) and class VII-C (experimental class) at SMP Kristen 2 Salatiga. Data analysis is carried out using inferential statistics with the Wilcoxon test, Man Whitney, and N-Gain score. The results of the validity and reliability test on the research instrument show that the instrument is valid and reliable. Based on the results of observations, the syntax of the cooperative learning model with Baurus pattern problem solving method is included in the fully implemented category with a score of 4.9. Students also give positive response with a score of 0.9. The results of the Wilcoxon test show that the cooperative learning model with Baurus problem solving method has an effect on collaborative skills with a p-value of 0.00 α 0.05 and an N-Gain score reaching 0.7 (high). The results of the Man Whitney test show a p-value of 0.00α0.05, which means there is a significant difference in influence between the cooperative learning model with Baurus pattern problem solving method and STAD cooperative learning model.

Abstract

The objectives of this study were 1) to improve student's critical thinking skills through Problem Based Learning (PBL) with a Lesson Study approach on respiratory system material; 2) to analyze students' critical thinking skills in studying the respiratory system; 3) to determine the differences in the effect of the PBL-LS and PBL learning models on critical thinking skills in the material of the respiratory system. This study used a quasi-experimental design. The subjects in this study were XI MIPA 1 and XI MIPA 2 grade SMA Negeri 1 Salatiga. This research was conducted in the even semester of the 2022/2023 Academic Year from September 2023 to May 2022. The data analysis technique used is quantitative descriptive analysis. Based on the research results, it is known that there is an influence of the PBL-LS learning model on critical thinking skills (p-value 0.05) with an N-Gain of 0.5 (moderate). The results of the analysis of each indicator of critical thinking skills showed from that the lowest indicator to the highest indicator of critical thinking skills was found from the inference (65,8); reason (69,4); clarity (69,8); focus (72,8); overview (75,0); situation (79,7). In addition, it was also found that there was a difference in the effect of the PBL-LS and PBL learning models on critical thinking skills (p-value 0.05).

Abstract

Lake Rawa Pening is one of the natural resources with abundant local potential that can be utilized in the world of education and the surrounding community. The objectives of this study are: a) to determine the local potential of Lake Rawa Pening, and b) to determine the level of knowledge of junior high school students about Lake Rawa Pening related to local potential of the Lake in relation to science learning materials. The subjects of the study were grade IX junior high school students in eight schools around Lake Rawa Pening. Interviews and tests were used fordata collection technique. Data analysis were carried out by calculating students' scores and interpreting them into the minimum completion criteria (KKM) category by the Ministry of Education and Culture.  Based on the results of the study, it is known that there are twenty-four types of fish, one type of lobster, one type of shellfish, five types of birds, twenty types of plants, and two types of inanimate objects that are included in the local potential of Lake Rawa Pening. Based on the results of the study, the average value of junior high school students' knowledge about the local potential of Lake Rawa Pening in relation to science learning materials only reaches 63, which it is categorized as insufficient. It was found that students' knowledge in insufficient category is 77%, the sufficient category is 19%, the good category is 4%, and no students were found to have knowledge in the very good category.

Abstract

Lesson study is a teacher collaborative approach to professional development. Lesson study is a model for fostering educator professionalism through collaborative and continuous learning assessments based on collegial and mutual learning principles to build learning communication. The aim of this research is to get an overview of science teachers' knowledge about lesson study as a professional inquiry approach in learning. Surveys of lesson study activities carried out by teachers can help to understand the characteristics of professional learning through effective lesson study and the extent to which teachers carry out and are involved in the lesson study process. The research was conducted in Salatiga, Central Java, Indonesia. This research method uses quantitative descriptive. The data collection technique uses a survey using a questionnaire as an instrument consisting of 70 statements from seven categories regarding lesson study. Respondents were science teachers selected using purposive sampling. Data analysis uses percentage techniques. Based on a survey conducted on science teachers regarding the implementation of lesson study, it is known that there are 5% of respondents who have never heard of lesson study, 30% of respondents have never been involved in lesson study activities, and there are around 40 % of respondents who have never carried out lesson study activities in teaching. Based on the seven categories of lesson study asked to teachers who have carried out lesson study in learning, it is known that there are still teachers who have weak motivation to improve the quality of learning, there are still science teachers who do not understand how to implement lesson study and how to use time in lesson study. Apart from that, it was found that science teachers still had a weak understanding of the benefits of lesson study in increasing teacher collaboration, the benefits of lesson study in improving the quality of teaching and learning, and there were still science teachers who did not understand how lesson study was started.
