Penggunaan Pembelajaran Problem Based Learning (PBL) Untuk Mengurangi Miskonsepsi Pada Materi Asam Basa

This study aims to determine the effect of the use of Problem Based Learning towards reducing students' misconceptions on acid-base material. The learning model used in this study is the Problem Based Learning (PBL) learning model. The population in this study were all students of class XII IPA in Tomitas Caritas Catholic High School while the sample used was class XII IPA 2. Data collection techniques used a two-tier diagnostic test. Analysis of the data used in this study is the Rasch model and hypothesis testing. The results showed that there were still students who experienced misconceptions even including students who had high abilities, and the average pretest learning outcomes = 48.6 while the average posttest learning outcomes = 86.6. The results of the study for the hypothesis test were analyzed using the T-test statistic at a significant level of 0.05 and the results obtained were obtained at 7.90> 1.684 Ttable so that H0 was rejected and H1 was accepted. Based on these results it can be concluded that the use of Problem Based Learning learning models can reduce student misconceptionsThis study aims to determine the effect of the use of Problem Based Learning towards reducing students' misconceptions on acid-base material.

Analisis Logam Timbal (Pb) sebagai Pembelajaran Menggunakan Model Problem Based Learning Kabupaten Kepulauan Sangihe

The impact of the use of refined petroleum on potential pollution in mangrove allows the presence of lead metal (Pb) in the Sangihe Islands Restoration and Learning Center and the use of mangroves in the Sangihe Islands Restoration and Mangrove Learning Center as a place of learning has not been carried out to the full. Therefore, in this regard, a study was carried out by analyzing Pb metals in sediments, Gastropod shells and Bivalvia shells in the research subsystem zone of the Sangihe Islands Restoration and Mangrove Learning Center which were then designed into learning designs using a model of problem based learning. The research method used is an exploratory method. Pb metal analysis was performed using an Atomic Absorption Spectrophotometer instrument resulting in an average Pb metal in sediments was 0.402 ppm, in Bivalvia shells was 0.04283 ppm and Gastropods shells was 0.0654 ppm. Based on the results of the analysis, it can be concluded that the presence of Pb metal in sediments, Bivalvia shells and Gastropod shells then yields four main questions in the learning design with Sub-Impacts of the Use of Petroleum using the problem based learning model.

Pengaruh Model Pembelajaran Anchored Instruction terhadap Hasil Belajar Siswa

This research is an experimental study using the Anchored Instruction learning model. This study aims to determine the effect of the Anchored Instruction learning model on student learning outcomes on the mole concept subject. This research was conducted in class X SMA Negeri 2 Siau Timur with a sample of 40 people. The research design used was a pre-test and randomized two group design. The experimental class uses the Anchored Instruction learning model and the control class uses the conventional learning model. Analysis of the hypothesis test using t-test with a significant level α = 0.05. The test results obtained indicate that the results of tcount> ttable or 2.112> 2.024, thus H0 is rejected and H1 is accepted, this shows that there is a significant difference between the average value of the initial test (posttest) of the experimental group and the control group. So it can be concluded that there is a difference between student learning outcomes using the Anchored Instruction learning model and student learning outcomes using conventional learning models on mole concept subject.

This study aims to determine the effect of POGIL learning models on student learning outcomes on acid-base titration subject. This research was conducted in class XI MIPA 2 and XI MIPA 3 in SMA Negeri 1 Kakas. The method used is an experimental method with a post-test only control design research design. The research sample consisted of 30 students, who were randomly drawn. The experimental class uses the POGIL method, the control class uses conventional learning. Student learning outcomes data obtained from post-test scores. Analysis of research data shows that there are differences in the average value of student learning outcomes of the experimental class taught by using the POGIL method and the average value of the learning outcomes of control class students who are taught by using conventional learning on mole concept material. Data analysis using t-test at a significant level α = 0.05. Statistical analysis of student learning outcomes obtained tcount > ttable or 3,078 > 2,048. So it can be concluded that there is a positive influence between student learning outcomes using the POGIL method and student learning outcomes using conventional learning on acid-base titration subject.
