Abstract

This study aims to comprehensively investigate students' learning approach in identifying, predicting, and generalizing object and number configuration. A qualitative method was applied with as many as 28 participants from eighth-grade students in Bandung, Indonesia. Students’ ability to recognize, predict, and generalize the configuration of objects and numbers was assessed. At the same time, the approaches employed in the process were analyzed. The research showed that students used different approaches to figure out the pattern of objects and number configuration. These approaches were: descriptive, operational, visual-descriptive, visual-operational, and descriptive-visual-operational. Keywords were typically employed in the descriptive approach to predict unknown objects or numbers. However, the descriptive approach could not accurately predict specific patterns. Therefore, students employed other approaches, including operational, visual-descriptive, visual-operational, and descriptive-visual-operational approaches. Unfortunately, all approaches have proven inadequate for formulating generalizations (general rules) independently. These results showed that when teaching students how numbers and objects are configured, they should be encouraged to try different ways of seeing patterns, such as descriptive, visual, operational, or a combination of the three.

Abstract

The study aims to examine students' mathematical communication skills on the material of straight-line equation through video-assisted learning using the Indonesian Realistic Mathematics Education (PMRI) approach and collaborative learning. The type of research is descriptive qualitative research with participants consisting of 20 students in the eighth grade of junior high school in the Palembang District, South Sumatera Province. This study comprised three meetings. The initial two meetings were dedicated to learning process using video material with PMRI and collaborative learning. The third meeting was utilized for result evaluation through testing. Data were collected through written tests, observations, and interviews using the descriptive data analysis approach. The findings of the study reveal that the combination of the PMRI approach, collaborative learning, and video learning on the material of straight-line equation has a fairly effective application. The students’ skills to communicate mathematically are identified. The most frequent indicator is expressing mathematical ideas, while the least frequent indicator is drawing conclusions. Students' mathematical communication skills can be improved by using learning video in conjunction with PMRI and collaborative learning during the learning process.
