2023-01-05T04:09:34+00:00

The Project Based Learning (PjBL) model has been widely implemented in schools; however, limited evidence is available regarding its impact on students’ creative thinking and science communication skills in public senior high schools in Poso City. This study aimed to describe the implementation of the PjBL model by biology teachers in promoting students’ creative thinking and science communication skills. The study employed a descriptive qualitative approach involving 60 respondents, consisting of 48 students from SMA Negeri 1 Poso, SMA Negeri 2 Poso, and SMA Negeri 3 Poso, as well as 12 biology teachers. Data were collected through questionnaires and unstructured interviews and analyzed descriptively. The findings revealed differences between students’ and teachers’ perceptions of PjBL implementation. Students’ responses were categorized as moderate (66.6%), whereas teachers’ responses were categorized as high (70.8%). Teachers’ efforts to encourage students’ creative thinking skills were rated moderate by both students (64.5%) and teachers (68.0%). Similarly, efforts to develop science communication skills were also rated moderate, with student responses reaching 55.9% and teacher responses 62.6%. Overall, the findings indicate that the implementation of PjBL has contributed moderately to fostering creative thinking and science communication skills among senior high school students in Poso City.

Comparison of Problem Solving Between the Use of Columb’s Law and Gauss Law for the Determination of the Electric Field

2023-03-07T03:55:24+00:00

Problems are an essential part of human life, and problem-solving strategies have been shown to improve students’ critical thinking skills. This study aimed to describe students’ understanding of Coulomb’s law and Gauss’s law through problem-solving tasks in determining electric fields. The research was conducted during the odd semester of 2021 at Tadulako University using a qualitative descriptive approach. Six students were selected as respondents based on the Respondent Selection Test (RST), representing three ability levels: moderate, low, and very low, with two students in each category. Data were collected using essay-based problem-solving tests consisting of five questions and supporting instruments. Data credibility was ensured through credibility testing, and the results were analyzed descriptively. The findings showed clear differences in students’ problem-solving performance across the three ability levels. Most students were more familiar with applying Coulomb’s law than Gauss’s law when solving electric field problems. Students also experienced considerable difficulty determining the electric field produced by an infinitely long wire. The study concludes that while Coulomb’s law is more commonly understood, Gauss’s law serves as an effective alternative for determining electric fields, particularly in situations involving symmetrical charge distributions and homogeneous spatial geometries.

Blended Learning Using Google Classroom on Critical thinking ability and Science Communication in Class V Elementary School

2023-05-11T03:28:18+00:00

This paper briefly describes the background, problems, methods, and findings of a study on the use of Google Classroom-based blended learning to improve fifth-grade students' critical thinking and science communication skills at Madani Integrated Elementary School, Palu. The study aimed to determine the improvement of these skills in science learning through the implementation of blended learning. This quantitative research employed a quasi-experimental design using intact groups of fifth-grade students from the 2021/2022 academic year. Data were analyzed using significance testing and N-gain analysis. The results showed a significant improvement in students' critical thinking skills, with a significance value of 0.000 (< 0.05). The experimental class obtained an N-gain score of 70.51, categorized as moderately effective, while the control class achieved an N-gain score of 56.29 with the same category. The results also indicated a significant improvement in science communication skills, with a significance value of 0.000 (< 0.05). These findings demonstrate that the implementation of Google Classroom-based blended learning can improve the critical thinking and science communication skills of fifth-grade students in science learning at Madani Integrated Elementary School, Palu.

The Effectiveness of Merdeka Curriculum Teaching Modules in Terms of Students Self-Reliance on Learn Chemistry

2024-01-15T02:42:16+00:00

The research on the development of the Merdeka Curriculum teaching module on student self-reliance aims to measure validity, practicality, and effectiveness. The type of research used is Research and Development (R&D) with the ADDIE model. The sample of this study were students of class XI MIA MAN 2 Palu. The instruments used in this study were validation sheets, questionnaires, and multiple-choice tests. Data were analyzed using quantitative descriptive techniques. The results showed that the validity of the teaching module in the media aspect was in the valid category with a score of 79% and the media aspect was in the valid category with a score of 77%. The practicality of the teaching module was in the very practical category with a score of 81% and the student response obtained a score of 91% in the very good category. The effectiveness of teaching modules using Effect size d Cohen's with a value of 4.15 for the High category and a value of 3.88 for the Low category in a very large effect. Student self-reliance increased with an average percentage of 76% in the good category. Based on the research results, the Merdeka Curriculum teaching module is eligible for use.

Implementation of Project Based Learning Model to Enhance Science Creativity and Critical Thinking Skills of Students on Ecosystem Material in Primary School

2024-01-26T03:11:52+00:00

This research aims to determine the influence of implementing the Project Based Learning (PjBL) model in enhancing science creativity and critical thinking skills on the ecosystem material among fifth-grade students at SD Inpres Malei. The research sample consisted of 22 fifth-grade students enrolled in the academic year 2022/2023. The research method employed a quasi-experimental design with a one-group pretest-posttest design. Data collection involved observations and learning outcome tests. Data analysis utilized SPSS 23, involving tests for normality, homogeneity, and incidental sample T-test. The findings revealed that the pretest average scores for science creativity and critical thinking skills were 59.09 and 49.32, respectively. In the posttest, the average scores increased to 85.45 for science creativity and 79.09 for critical thinking skills. The mean differences between pretest and posttest demonstrated an improvement in learning outcomes. The average improvement for science creativity was 26.36 while for critical thinking skills, it was 29.77. The SPSS output yielded significance values lower than the significance level of 0.05 (0.000 < 0.005), rejecting H0 and accepting H1, indicating a positive influence of the Project Based Learning model in enhancing science creativity and critical thinking skills on the ecosystem material among fifth-grade students at SD Inpres Malei.
