The Role of Laboratory Activities on Laundry Industry Waste Pollution to Improve Problem Solving skills: Teacher's Perception
Get PDFThis study aims to describe the teacher's perception of problem-solving-based laboratory activities to improve the problem-solving skills of junior high school. This study involved 30 science teachers in Lampung. Collecting data in this study using a questionnaire, then analyzed using descriptive analysis. The survey results show that 65% of science teachers have not carried out problem-solving-based laboratory activities in their learning activities. This is due to several factors including teachers not being able to manage time in learning activities and limited tools and materials in school laboratories. Whereas on environmental pollution material for class VII of Junior High School, students can be invited to carry out laboratory activities based on solving real problems such as water pollution by laundry industrial waste. Based on the survey results, it can be said that the laboratory activity program is needed by teachers and students to improve students' problem solving skills.Keywords: laboratory activities, problem-based learning, problem solving skills.DOI: http://dx.doi.org/10.23960/jpmipa/v23i1.pp327-33

Development of Peer-Scaffolding-Based Learning Program to Train the Performance Assessment Ability of Prospective Science Teacher
Get PDFThe aim of the research is to develop a peer scaffolding-based learning program to equip prospective science teacher students with the ability to develop performance appraisals. This program was developed using a 4D model (Define, Design, Develop, and Disseminate), the development of which has reached the stage of feasibility testing (Develop). Data collection techniques with questionnaires to measure the validity of the feasibility of learning programs and essay tests for the ability to develop performance appraisals. The results of this study indicate that the learning program developed got an average score of 4.00 (very valid category) in all aspects of feasibility. The results of the program trial show that there is an increase in student abilities seen from their N-gain (0.41: moderate criteria). Improvement in the aspect of the ability to understand the scope of the assessment with “low” criteria (0.036), planning an assessment with “medium” criteria (0.72). Based on this, it is concluded that the program developed is quite effective in providing performance appraisal skills for prospective science teacher students.Keywords: learning program, peer scaffolding, performance assessment.DOI: http://dx.doi.org/10.23960/jpmipa/v23i1.pp284-29
Cognitive Conflict-Based Conceptual Change Model on Concept Mastery & Student Self-regulation
Get PDFThis study aims to determine the effect of the conceptual change model with a cognitive conflict approach on concept mastery & self-regulation of class X students in biology subjects. The quasi-experimental method with posttest only controls group design. The research population is students of class X Mathematics & Natural Sciences, class X Mathematics & Natural Sciences 1 as the experimental class, & X Mathematics & Natural Sciences 2 as the control class. Data collection techniques with concept mastery tests & self-regulation questionnaires. Data analysis used an independent sample t-test. Based on the results of the study, the average value of mastery of concepts in the experimental class was 71.14, & the control class was 65.52. The average self regulation in the experimental class was 73.29, in the control class it was 65.91. Independent sample t-test test shows that p-value> 0.05. This means that there is an influence of the conceptual change model with a cognitive conflict approach on concept mastery & self-regulation in class X in biology subjects.Keywords: conceptual change, conflict cognitive approach, mastery of concepts, self-regulationDOI: http://dx.doi.org/10.23960/jpmipa/v23i1.pp100-11
Students' Critical Thinking Disposition in Working on Numeration Problems
Get PDFThis study aims to describe the critical thinking disposition of students in working on numeracy problems. This research is qualitative research with a descriptive research type.

Bibliometric Analysis of Students' Errors in Solving Problems on Sets using VOSviewer
Get PDFLearning error can be interpreted as a certain condition marked by errors when someone completes a test. One of the causes of students' mistakes in answering questions is the lack of understanding of the concepts in the material. Research on student errors in solving problems related to set material uses the bibliometric method, which is still rarely done before. This research is indexed from Scholar with 500 articles obtained and extracted in the Publish or Perished (PoP) application. The articles obtained were published from 0 to 2022. The articles with the most article citations with 1837 citations occurred in 2020. After that, it was continued by visualizing the network, the number of cluster items was 10 red, 6 green and 4 blue, overlay and density by using the VOSviewer application. Therefore, it can be concluded that mathematical problem is one of the keywords that is still rarely studied. Keywords: students’ error, mathematics, bibliometric analysis, sets.
