Education is a conscious effort through planning that is prepared by considering various aspects that are important for developing student potential. One of the efforts can be made is implementing a cooperative learning model. This study aims to determine the differences in the results of the application of the Jigsaw cooperative learning model and role playing in physics as well as student responses to the application of the two learning models. This research procedure uses mixed methods using quantitative data obtained by questionnaires, qualitative data is obtained by conducting interviews. The results showed that there were still many students who responded well to the application of the jigsaw cooperative learning model in learning physics but in contrast to student responses to role playing learning. This study aims to determine student responses to the implementation of the Jigsaw cooperative learning model and role playing in physics subjects and to determine the differences in the application of those two models in physics subjects. The novelty of this study is to describe student learning outcomes with the physics learning process and student responses when using the jigsaw cooperative learning model and the role-playing model in physics to make it easier for students to learn and understand concepts and formulas in physics learning. The results showed that many students responded to the application of the jigsaw cooperative learning model and the role-playing learning model in physics learning well. The novelty of this research is that it can improve students' attitudes towards physics by using the jigsaw cooperative learning model and the role playing model.                                        Â
Science process skills and critical thinking are skills that are very important and must be possessed by students in the 21st century. The purpose of this study is to determine the scientific process and critical thinking skills in terms of gender and see whether there is a relationship between science process skills and critical thinking skills. student. This is because the researcher wants to see a comparison of the abilities of male and female students. This research is a type of quantitative research with a research design. The population of this study were students of SMAN 6 Batanghari and the samples used were students of class A and class B, totaling 80 students with a ratio of 50 female students and 30 male students. The sampling technique used is simple random sampling with the criteria of students who are in Accredited Schools A and Class XII students who have studied the latest direct material. The search instrument used was an observation sheet and a critical reflectance test sheet. The data analysis used is descriptive statistical analysis and deductive analysis. Based on the results obtained, it can be concluded that the science process skills and critical thinking skills of female students are higher than male students. besides that there is a high and positive relationship between students' critical thinking skills and students' critical thinking skills. Based on these results, this research can be useful for teachers, namely so that teachers can carry out learning that can develop and improve science process skills so that students' critical thinking skills can also increase. In addition, the benefits for students themselves are so that students are accustomed to using skills in the learning process and can provide critical solutions in solving problems.
The purpose of this study was to determine student attitudes towards learning physics in high schools in the city of Jambi and Batang Hari. The method used is a survey type quantitative research method. The data collection technique in this study used purposive sampling technique with the research instrument used was a questionnaire instrument. The data analysis used in this research is descriptive analysis. Based on the results of the study, attitudes based on indicators of social implications, scientist normality, and attitudes towards physics research conducted at SMAN 8 Jambi City with the physics attitudes at SMAN 10 Batang Hari can be concluded that the results displayed are different from the category results and the number of respondents. So that there are different conditions from the two SMAs. This comparison also shows that SMAN 8 Kota Jambi shows a better attitude seen from the percentage and number of respondents.
This research was carried out on Jl. Makmur, Dusun III Banyumas Village, Stabat District, Langkat Regency, North Sumatra This research was carried out from December to March 2022. Materials used: Water-honey guava brood tree, honey-water guava shoots of green delli variety, Growtone, Npk 16-16-16 Fertilizer. This study was arranged based on a factorial randomized block design (RAK) with 2 treatment factors and 3 replications. The first factor was the administration of Growtone consisting of 4 levels, namely: G0: Without Growtone (control), G1: 0.5% (5 gr100 ml-1). water), G2: 1.0% (10 gr100 ml water-1), G3: 1.5% (15 gr100 ml water-1). The second factor is the application of NPK 16-16-16(N) fertilizer consisting of 3 The levels are: N0: Without NPK 16-16-16 fertilizer (control), N1: 0.2 g100 ml water-1, N2: 0.4 g 100 ml water-1. The results of the study showed that the application of ZPT Growtone had a very significant effect on the parameters of the longest root length and the number of roots, had a significant effect on the parameters of plant height, number of leaves, and number of shoots, but had no significant effect on the parameters of the percentage of cuttings growing. The application of NPK 16-16-16 fertilizer had a very significant effect on the parameters of plant height, significantly on the parameters of the number of leaves, the number of shoots, the longest root length, and the number of roots, but had no significant effect on the parameters of the percentage of cuttings growing. The interaction of giving zpt growtone and giving NPK 16-16-16 fertilizer had no significant effect on all observation parameters
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
