Abstract

One of the skills in physics learning is problem-solving skills. However, this skill is not sufficiently trained at school. Therefore, this study aims to analyze the effectiveness of mechanical wave teaching materials that apply direct teaching models to improve students' problem-solving skills. This is a quantitative descriptive research with one group pre-test post-test design on 28 class XI MIA 2 SMA Negeri 1 Alalak students. According to Heller, data collection was obtained through problem-solving tests using indicators of problem-solving skills: visualizing problems, describing problems, planning solutions, implementing solutions, and evaluating problems. The study results stated that the mechanical wave teaching materials effectively improved students' problem-solving problem-solving by producing a problem-solving test N-gain score of 0.83 with a high category. This also shows an increase in students' problem-solving skills. Thus, teaching materials for mechanical waves using the direct teaching method are effectively used in physics learning to improve students' problem-solving skills at school.

Abstract

Scientific creativity involves creating innovative ideas, thoughts, or concepts. Scientific creativity in schools is not sufficiently trained. This study aims to produce valid, practical, and effective dynamic fluids student worksheets that are suitable for enhancing students' scientific creativity. This study applied the ADDIE model with 34 test subjects from the XI MIPA 3 class at SMA Negeri 8 Banjarmasin. Data were obtained from validation sheets, student response questionnaires, and learning outcome tests. The results showed that: (1) The student worksheets is considered valid because the validation results of the student worksheets and learning outcome tests were categorized as very good; (2) The student worksheets is considered practical because the results of the student response questionnaires were categorized as good; (3) The student worksheets is considered effective because the N-Gain of scientific creativity was 0.70, which falls into the high category. The developed dynamic fluids student worksheets is appropriate for enhancing students' scientific creativity in physics learning. Teachers can use this the student worksheets as an alternative to improve students' scientific creativity in physics education efforts.

Abstract

Problem-solving skills are one of the 21st-century skills that students must master, but most students still have not mastered them. This research aims to describe the implementation and obstacles to implementing STEM-oriented direct instruction to improve students' problem-solving skills. This research is descriptive and qualitative in analyzing students' problem-solving skills. The subjects of this research were 20 students in class XI MIPA. The tools used are sound wave teaching materials that have been validated, and research instruments are student response questionnaires, and researchers act directly as teachers. Data analysis is carried out by reviewing the results obtained in the field through interviews, observations, and a collection of other documents. The data analysis stages in this research used the Miles and Huberman model: data classification, data display, and data validation. It was concluded that the implementation of learning took place according to the STEM-oriented direct instruction syntax, and several factors hindered the improvement of students' problem-solving skills, including internal factors, namely from within the students, and external factors, namely from the teacher and school.

Abstract

Problem-solving skills are among the key competencies in 21st-century life, yet they are poorly trained in schools. This study aims to produce a direct teaching-oriented temperature and heat worksheet that is feasible to use to improve students' problem-solving skills. The ADDIE design was used in the development of this worksheet. The worksheet was tested on 25 students in Class XI SMA. Data was measured using validation instruments, response questionnaires, and problem-solving tests. The results showed that the developed student worksheet was categorized as very valid, the student's response to using the worksheet was categorized as practical, and the student worksheet was categorized as effective because the N-Gain of problem-solving of 0.56 was categorized as moderate. This means that the developed direct teaching-oriented student worksheet is feasible to improve problem-solving skills. This student worksheet can be an alternative for teachers to equip 21st-century competencies, especially problem-solving skills.
