Abstract

The study aimed to determine the effect of principals' learning leadership and innovative behaviour in implementing School-Based Management in SD Negeri Dolok Pardamean District, Simalungun Regency in 2021. This type of research was explanatory, so the appropriate method used was the survey method of 15 school principals as research respondents. The research instrument is a questionnaire containing 25 positive and negative statements with five answer choices located on a continuum line according to the Likert scale model and in the form of a closed questionnaire. Before being used, the questionnaire has been tested, and the results can be used as a research instrument. Data analysis techniques include descriptive analysis, requirements analysis tests, and hypothesis testing. Descriptive analysis was conducted to obtain an overview of the data from each research variable which was shown through the mean, median, mode, frequency distribution, and graphs. To identify the trend of each research variable, the average ideal score (Mi) and the ideal standard deviation (SDi) were used. Supported by the very strong learning leadership and innovative behaviour of the primary school principal; (3) Based on hypothesis testing, the results of the calculation of the value of th tt at a significance level of 0.05 are 5.96 2.02. The conclusion that there is a significant influence on learning leadership and innovative behaviour of elementary school principals in implementing School-Based Management is accepted as true.

Abstract

The goal of this study is to see how problem-solving learning paradigms affect students' grasp of physics ideas. This study is a quasi-experimental study. The sample was chosen using the cluster random class methodology, which consisted of two classes, the first of which was taught using a problem-solving learning model and the second of which was taught using traditional methods. Experiment classes provide problem-solving opportunities to help students better understand physics ideas, while control classes are taught in a traditional manner. Pre- and post-test results from students in both classes were used to collect data. The two-way Anava-test was applied, and the level of significance was found to be 0.000 (sig. 0.05), indicating that problem solving learning is beneficial in improving students’ understanding of physics concepts.

Abstract

Basic physics experiment textbooks are widely used by lecturers and students in physics courses at universities, but relevant and easy-to-use basic physics experiment textbooks are not yet available. Most of the available books are practical books. The purpose of this study was to determine the stages of developing a basic physics experimental textbook based on pictorial riddles. This type of research is research and development (R&D) research. The research uses the Plomp Model with three stages, namely preliminary research, prototype or development, and assessment. The subjects of this study were students of the Physics Education study program at the University of HKBP Nommensen Pematangsiantar. Data analysis used descriptive quantitative. The results showed that the development value of pictorial riddle-based textbooks had a high level of attractiveness based on the assessment of material/content experts reaching 93.75%. The development value based on pictorial riddle has a high level of attractiveness based on field test assessments reaching 91%. This shows that the development of pictorial riddle-based basic physics experimental textbooks has good quality and is suitable for use to improve student learning outcomes in basic physics experimental subjects.
