Implementation of Problem-Based Learning to Improve Students' Understanding of Basic Probability Concepts

Ageng Triyono — 2025-07-31

The purpose of this study was to improve the understanding of class X students towards the concept of probability. The purpose of the study was achieved using a classroom action research method whose action cycle follows the Kemmis & Taggart Model. The classroom action given was the application of a problem-based learning model for 3 cycles. The subjects involved were 12 class X students, the researcher as a teacher, 1 senior teacher as a validator of learning devices and test instruments, and 1 principal as an observer. The research data was taken using a probability concept understanding test instrument in the form of 5 descriptive questions, which were given at the end of each cycle. Learning outcome data were analyzed by calculating the average score and percentage of learning completion. Other data in the form of observer notes were taken using an observation sheet. After the classroom action was carried out, the average score of learning outcomes increased from each cycle, which increased by 33 from cycle I to cycle II, and increased again by 9 from cycle II to cycle III. The application of the problem-based learning model in this study was said to be successful because the achievement of student completion had exceeded 75%, namely in cycles II and III. Thus, the results of this study can be a recommendation for teachers who want to teach the concept of probability.

This study aims to evaluate the quality of quiz questions for student-level students, organized by the Mathematics Education Study Program, FTIK IAIN Pontianak together with the Mathematics Education Student Association. The evaluation was carried out based on aspects of material, construction, language, and Bloom's Taxonomy. The mathematics materials presented in the competition include Algebra, Geometry, Number Theory, Trigonometry. Data were taken from documents of questions, answers, and participant scores. The analysis showed that the majority of questions were of good quality, although some aspects, such as the balance of cognitive levels in Bloom's Taxonomy, needed improvement. This study is expected to be the basis for the development of similar competitions in the future

STUDY OF CLASSICAL ASSUMPTION TEST USING SPSS

Kartini Hutagaol — 2025-07-31

The purpose of this article is to provide examples of the correct steps in using statistical tools in non-exact research. The use of statistical models should be appropriate to the problem being studied and the research needs. If statistical tools are not tailored to the research needs, the research results will be less reliable and will jeopardize the accuracy and validity of data interpretation. In reality, errors still occur in the use of statistical analysis tools. Therefore, this article can be useful as an example to assist students in writing their theses, specifically regarding the use of classical assumption test models. It is hoped that errors can be corrected to ensure the accuracy and validity of data interpretation are in line with the assumptions of the research problem.
