Abstract

This article reports on the validity of CTL-based physics e-books and the effectiveness of media developed for student problem-solving skills. This research is development research and uses a quantitative approach. The subjects of this research were 17 students of class X science class and 26 students of class X social class at one of the senior high schools in Yogyakarta as the implementation class and modeling classes. The results of this study indicate that the development of a CTL-based physics e-book on simple harmonic oscillation material is feasible in terms of expert validation results where the average total validation score is 3.75 with a very high category. The use of a CTL-based physics e-book in the learning process is able to have a significant influence on improving the problem-solving skills of students in both classes, which is indicated by the value of sig. (2-tailed) of 0.00 both for modeling and implementation classes which are smaller than the alpha value of 0.05.

Abstract

This research aims to develop physics e-book-based jigsaw cooperative learning (JCL) assisted by WhatsApp. This article describes the results of the validity and effectiveness of the developed media on physics learning outcomes in terms of student learning motivation. This article also describes the relationship between initial ability and learning motivation on student learning outcomes. This research is development research with a 4-D model. This research was implemented with a quasi-experimental using a pretest-posttest control group research design. The sample in this research was 70 students of 10th grade science class at one of the high schools in Yogyakarta. The results of this research indicate that the development of WhatsApp-assisted JCL-based Physics e-book on the topic of straight motion is valid and reliable. This is evidenced by the results of the validator where the average value of validity and reliability is 0.75 in the high category and 94 in the reliable category. The use of WhatsApp-assisted JCL-based Physics e-book has a significant effect on improving student learning outcomes. This is indicated by the significant value is 0.00 < 0.05. By analysis of covariance, initial ability and learning motivation have a relationship with student learning outcomes. This is indicated by the squared value of the regression coefficient is 38.6%.

Abstract

This work reports the production and characteristics of silver nanoparticles by electrolysis method at different voltages and electrolysis time with respect to their soluble concentration. This research is an experimental research. The research sample was the result of a solution of silver nanoparticles by the electrolysis method. The purpose of this research was to determine the effect of electrolysis voltage on the concentration of silver nanoparticles, the effect of electrolysis time on the concentration of silver nanoparticles, and characterization using UV-Vis, AAS and PSA. In this research there are two stages, namely the production stage and the characterization stage. The production of silver nanoparticles was carried out using 99% AgBr rods and aquades by electrolysis method. Characterization was carried out by testing on UV-Vis, AAS and PSA spectrometers to determine light absorption, ionic silver concentration and silver nanoparticle size. The results of this research indicate that the greater the electrolysis voltage and time, the higher the concentration of the solution obtained. The concentrations obtained at each voltage were 38 ppm, 42 ppm and 54 ppm. Characterization using UV-VIS spectrometer showed that the silver nanoparticle solution at each concentration was able to absorb light at wavelengths of 419.50 nm, 442 nm and 431 nm with absorbance peaks of 1,158, 2,989, and 0.904. Characterization using AAS showed that the content of silver nanoparticles in solution at each concentration were 8.7 ppm, 15 ppm and 17 ppm. Characterization using PSA showed that the solution at each concentration had silver nanoparticle sizes were 110.7 nm, 209.2 nm, 175.2 nm.

Abstract

The socialization of partnerships between teachers and parents in the implementation of deep learning is a strategic effort to build a collaborative educational environment centered on students’ needs. The main goal of this activity is to strengthen mutual understanding of the importance of synergy between teachers and parents in supporting a meaningful, reflective, and sustainable learning process. The socialization was carried out through discussions, counseling sessions, and the exchange of experiences and best practices between schools and parents. The results show that open communication and strong cooperation enhance support for character development, critical thinking skills, and students’ learning independence. Furthermore, this activity fosters a shared commitment to creating a positive learning atmosphere both at school and at home. Therefore, collaboration between teachers and parents in deep learning serves as a key element in improving the quality of education and can be used as a model for other schools, especially in areas with similar socio-cultural and geographical conditions.
