Abstract

The 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.pp284-293

Abstract

This 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.pp327-334

Abstract

Creative thinking skills have an important role to face the challenges of the 21st century. This study aims to improve the creative thinking skills of junior high school students through a project-based learning model for processing cassava peel waste. This research method is quasi-experimental, non-equivalent pre-test-post-test control group design. The sample in this study was class VII students of SMPN 1 Purbolinggo, who were determined using a purposive sampling technique. The number of students in the control and the experimental classes was 32 people each. The instruments in this research are the Creative Thinking Skills Test and Performance Assessment. The results showed that the average N-gain for creative thinking skills in the experimental class was in the medium category (0.58), while on the control class, it was in the low category (0.29). Cohen's d coefficients for each indicator of creative thinking skills fluency, flexibility, originality, and elaboration; were 0.62, 0.58, 0.72, and 0.72, respectively, all in the medium category. However, Cohen's d coefficient effect size for the average N-gain overall creative thinking skills is 2.40, belonging to the very large category. Based on these results, it can conclude that the project-based learning model is effective with a very large effect on improving students' creative thinking skills.Keywords: creative thinking skills, project-based learning models, cassava peel waste.DOI: http://dx.doi.org/10.23960/jpmipa/v23i4.pp1850-1861
