Abstract

This study aims to develop students' abilities in interpreting and making reasoning about physics data. The type of research used is experimental research. Physics learning was carried out in two classes: control and experimental groups. In the experimental group, physics learning was oriented to student activities where students dealt with physics objects. In contrast, in the control group, physics was taught conventionally by applying direct learning. The ability to interpret and to make reasoning about data was obtained through written tests conducted on pre-test and post-test. Analysis of research data was carried out by qualitative descriptive and t-test statistical analysis. The descriptive analysis was performed to describe students' abilities to interpret and to make reasoning about data. A statistical t-test analysis was conducted to determine the difference in the impact of treatment on the two groups. The results showed that the average ability to interpret data and to make reasoning about data in the experimental group was 76.91 and 76.99, respectively, while in the control group, it was 53.33 and 63.08, respectively. The results of the t-test analysis showed that the 2-way (t-tailed) significance value was 0.000 < 0.05, so it could be stated that there was a difference in ability between the control group and the experimental group. Based on the results of these studies, it can be noted that learning physics that involves a lot of student activities that interact directly with physics objects can improve the skills of high school students in interpreting and reasoning scientific data.

Abstract

Apple tomatoes with the scientific name Lycopersicum Pyriporme can last 7 days at room temperature and 14 days if stored in the refrigerator. The purpose of this study was to examine the effect of the ELF magnetic field intensity 600 uT and 1000 uT for 30, 60 and 90 minutes on the degree of acidity (pH), density (ρ) and physical quality of apple tomatoes. The research design used was RAL (completely randomized design). Data collection on the pH variable begins with crushing the tomatoes and then measuring the pH value of each fruit using a digital pH meter. The density variable was obtained by weighing the mass of each fruit and dipping the fruit in 150 ml of distilled water as the initial volume, then the difference between the final volume and the initial volume was obtained to obtain the final density of each fruit using the density equation. Physical condition variables can be obtained by counting the number of good fruits and recording each measurement. Observations were made for 20 days with data collection on the 0, 4th, 8th, 16th, and 20th days. The results showed that there were differences in the value of pH, density and physical quality of tomatoes between the control group and the experimental group. Exposure to the ELF magnetic field can affect the activity and reproduction of pathogenic microorganisms in apple tomatoes so as to maintain the pH value, density and physical quality of apple tomatoes.

Abstract

Lesson study was a practical approach to improve the quality of instruction and use widely in professional development programs for teachers. This article presents an innovative approach to developing the instruction ability and skills of science teacher candidates when actual teaching practice in a classroom through lesson study. Based on the lesson study approach, science teacher candidates worked collaboratively to understand the curriculum and state the desired learning outcomes; design lesson plans; teach a common lesson in 4 different classrooms; and conduct reflection to share, discuss, and refine their lesson. The teaching abilities and skills are assessed based on knowledge of the subject matter, quality of lesson plans, and learning practices. The result showed that the lesson study approach was a vital structure that helped science teacher candidates improve their teaching skills and ability. The research result gives implications for development programs for science teacher candidates will be discussed in light of these findings.

Abstract

The implementation of this research is limited by setting the problem of critical thinking skills to the problem of superior products in Jember, namely Cocoa students in Jember. This research was carried out using local wisdom on the subject matter of fermentation in cocoa beans. Students' thinking ability is carried out through filling in the work on test questions in the form of descriptions. The research will be carried out in October-November. The results of the research are the critical thinking skills of vocational students with a score of 76.53 higher than high school students with an average score of 62.37 for critical thinking skills. This shows that vocational students understand more about Jember's superior product, namely cocoa. Being in a district with one of the leading products, namely cocoa, makes vocational high School students equipped with knowledge about cocoa commodities, such as cocoa seeds, cocoa product development and cocoa processing methods. Thus, it is hoped that high school and vocational high school students will be able to make a maximum contribution in efforts to develop local products so that they can increase the progress and welfare of the local area. Problem-based learning that links learning materials and local wisdom is needed to support the improvement of students' critical thinking skills.
