Abstract

Digital technology has not yet been integrated to create an innovative learning media ecosystem. Utilization of local potential as a medium for ecosystem learning is still rarely done. Student learning outcomes in ecosystem Materi are still less than optimal. This can be seen from the scores of many students who are still incomplete. So it is necessary to develop an E-Catalog for class X ecosystems at SMA Negeri 12 Semarang. The aim of this research is to analyze the validity, practicality and effectiveness of the E-Catalog. This type of research is research and development with an ADDIE design (Analyze, Design, Development, Implementation, Evaluate). Media validity is measured using a validity assessment questionnaire by Materi and media experts. The practicality of the media is measured by teacher and student response questionnaires. The effectiveness of the Ecosystem E-Catalog is measured by learning outcome tests. Data were analyzed using descriptive percentage techniques. The results of the validator assessment stated that the Ecosystem E-Catalog media was very valid. In the small scale trial, 50% of students thought the Ecosystem E-Catalog was very practical and 50% of students thought it was practical. In a large-scale test, teachers and 69% of students thought the Ecosystem E-Catalog was very practical. All students have completed learning about Ecosystem materi . The Ecosystem E-Catalog is very valid, very practical and effectively used for teaching and learning activities at SMA Negeri 12 Semarang.

Abstract

The The demands of 21st century learning and the Independent Curriculum have not been fully implemented well, especially the creative abilities of students at SMA N 1 Jakenan. Based on observations made at SMA Negeri 1 Jakenan, it was found that students were less active during learning so that students' creativity was less developed. Students also still need additional learning resources apart from using LKPD and textbooks. This research aims to analyze the influence of the Picture and Picture model with the JAS approach (PICJAS) on students' cognitive and creative learning outcomes in Plantae material. This research is a type of quasi-experimental research with a Pretest-Posttest Nonequavalent Control Group Design. The samples used in this research were X3 (experimental class) and X4 (control class) which were taken using purposive sampling technique. The data collection technique in this research is using tests, product assessment, observation and giving questionnaires. Data analysis was carried out using the independent sample t-test for student cognitive learning outcomes and the Mann Whitney test for student creativity outcomes. Based on data analysis using the independent sample t-test and the Mann Whitney test, a significance value of 0.00 and 0.00 was obtained, because the sig value < α (0.05) means that there is a significant difference between the classes given the model treatment. PICJAS with classes treated with the lecture and discussion method or H0 is rejected and H1 is accepted. These results show that there is a significant influence from implementing the PICJAS learning model on improving students' cognitive learning outcomes and creativity. This influence can make the PICJAS model an alternative learning model that can improve students' cognitive learning outcomes and creativity.

Abstract

The skills that can be developed through education are 21st century skills, including the ability to solve problems related to issues faced in everyday life. Therefore, students need to be taught problem solving by using PBL model based on multiple representations on ecosystem material. The purpose of this study was to analyze the effect of PBL based on multiple representations in class X ecosystem material on students' problem solving skills. The research design used is an experiment with the quasi experiment method. The population in this study were all grade X students at SMAN 14 Semarang in the 2023/2024 school year. Sampling in this study using purposive random sampling technique based on the teacher's consideration that the selected class has a balanced ability. Two classes were sampled, namely class X5 as the experimental class which was given treatment using PBL model based on multiple representations and X9 as the control class which was given treatment using PBL model without multiple representations. Based on the results of the research, students' problem solving skills have increased in both experimental and control classes. The N-Gain test results of the experimental class are 0.3661 which means an increase in problem solving ability is moderate, while the N-Gain results of the control class are 0.1544 which means an increase in problem solving ability is low. The T-test results show that there is a significant difference between the average pretest-posttest scores in the experimental class and a significant average difference between the posttest scores in the experimental and control classes. The results of the Spearman Rank correlation test show that the Sig. (2-tailed) 0.880>0.05 which means that the application of PBL based on multiple representations has no effect on students' problem solving skills on ecosystem material. This can be influenced by several factors, namely the PBL model used, the formation of discussion groups, and also the number of multiple representations taught to students.

Abstract

At SMA Negeri 1 Tengaran, students' critical thinking and collaboration skills in environmental change material are still low. This is reinforced by student learning results in environmental change material which show that only 40.62% of students meet the criteria for achieving learning objectives and the results of the collaboration skills questionnaire which show that 32.3% of students find it difficult to collaborate with friends. These results are motivated by the low level of student involvement in learning so that a student-centered learning model is needed, such as the NHT type learning model assisted by problem-based LKPD. This learning model can train critical thinking skills through learning activities that invite students to think in solving problems on the LKPD while also training students' collaboration skills through group collaboration. The aim of this research is to analyze the effect of implementing the NHT type learning model assisted by problem-based LKPD on students' critical thinking and collaboration skills in environmental change material. The research is Pre-Experimental research with one group pretest-posttest. The research sample consisted of classes X-1, X-4 and X-5 which were selected using purposive sampling techniques. Critical thinking skills data were analyzed using the paired sample T-test while collaboration skills data used the Wilcoxon test. The results of the Paired Sample T test show a significance value of 0.000 (<0.05), meaning that the use of the NHT model assisted by problem-based LKPD has an effect on students' critical thinking skills. Each aspect of critical thinking has an N-gain value > 0.3 with the highest N-Gain in the indicators of advanced clarification and strategies & tactics. For the collaboration variable, the results of the Wilcoxon test show an Asymp.Sig.(2-tailed) value of 0.000 (<0.05), meaning that the use of the NHT model assisted by problem-based LKPD has an effect on collaboration skills. Each aspect of collaboration has an N-gain value > 0.3 (medium category) with the highest N-Gain in the indicator of working in a group. Based on these results, it can be concluded that the application of the NHT model assisted by problem-based LKPD has an effect in improving students' critical thinking and collaboration skills at SMA Negeri 1 Tengaran in environmental change material. The results of this research can be used as an alternative learning model to improve students' critical thinking and collaboration skills.
