Abstract

Lack of interest in learning inverse matrix mathematics causes a lack of interest in learning mathematics and produces unsatisfactory results. Researchers tried to conduct experimental research on the application of the Index Card Match learning model to mathematics learning outcomes in Inverse Matrix material at SMA Negeri 21 Makassar. The approach used is a quantitative approach with a pre-experimental method with a One Group Pretest Posttest design. The data collection techniques used are tests, observation, interviews and documentation. Meanwhile, data analysis uses the normality test and the Simple Paired T-Test hypothesis test. The results of this research were hypothesis testing on the pretest and posttest which obtained results of 0.000 < 0.05. H0 was rejected and Ha was accepted. From these results, it means that the application of the Index Card Match model has an influence on cognitive mathematics learning outcomes in inverse matrix material for class XI students at SMA Negeri 21 Makassar..

Abstract

This research is a type of quantitative descriptive research that aims to describe the conceptual changes of prospective physics teacher students on the topic of light interference after the application of the Conceptual Change Text. The steps taken are 1) Observation and definition, 2) designing the Conceptual Change Text, 3) collecting student conceptions, 4) applying the Conceptual Change Text in learning, 5) data analysis, and 6) interpretation of student conceptual change data. The subjects of this study were 35 prospective physics teacher students who were programming the Basic Physics course. The results of this study indicate that in the concept of the conditions for the process of light interference are 80% experienced construction and 56% experienced reconstruction; the concept of constructive-destructive interference obtained 82% who experienced construction and 88% who experienced reconstruction; and in the concept of interference in thin layers defined 67% experienced construction and 54% who experienced reconstruction. It can be concluded that most prospective subject teachers with different initial conceptions can achieve deep and complete conceptual understanding through the process of construction (having no conception to becoming a scientific conception) and reconstruction (misconception to becoming a scientific conception) through the Conceptual Change Text.

Abstract

Educational math game creates a fun learning experience for students. Following this rationale, this research-and-development study aims to elaborate on the process of developing ICT-assisted instructional media named “GAMA”, an educational math game tailored to Contextual Teaching Learning approach. We analyzed the feasibility of the game media to support the instruction on the concept of numbers at the first grade of elementary education. The subjects of this research were the first-grade elementary school students. The study applied the ADDIE development model consisting of five stages with an evaluation at each stage. The research results demonstrated that the game achieved a decent validity score. The practicality test, conducted through questionnaires and observations, documented a practicality score of 90.36%. In addition, the game satisfied the effectiveness test as evaluated through the comparison of students’ learning outcomes based on the N-Gain score of 0.76. This implied a significant difference between students' understanding before and after using educational math games.
