Abstract

This research aims to know the developing process of STAD type cooperative based on learning structure of mathematical subject; proportion meteri in the grade VII on SMPIT Assalam Ambon to achieve the valid, practical and effective learning instructional design. Learning instructional design which has been develop to student in the grade VII on SMPIT Assalam Ambon is learning Instructional devices planning, student task sheet, and student handbook. This research is a development research which used thiagrajan, semmel and semmel 4D model. The validation process of learning instructional design include competent validators on mathematics learning instructional design. Practical data analysis are achieve from observation result data of learning device and effectiveness data analysis of learning devices achieved from four sources which is 1) teacher ability of maintain the STAD type cooperative based learning. 2) students activities. 3) students responses. 4) learning results. The result of this research shows that learning devices of STAD type cooperative based learning which has been developed is valid, practical and effective

Abstract

The development of students’ computational thinking skills in mathematics remains a significant challenge, particularly due to the lack of adaptive instructional support that aligns with students’ cognitive stages. This study aims to analyze students’ needs for the scaffolding method in the process of mathematical computational thinking based on APOS theory. The research was conducted at Muhammadiyah Middle School Ambon using a descriptive approach with quantitative data support. The instruments used consisted of a computational thinking ability questionnaire and a scaffolding needs questionnaire. The results indicate that most students are still at the basic to intermediate levels of computational thinking and show a high need for scaffolding, especially in the action and process stages of the APOS framework. Furthermore, the findings reveal a strong relationship between students’ computational thinking ability and their need for scaffolding. These results suggest that scaffolding-based learning should be designed adaptively and systematically to support the gradual development of students’ computational thinking skills. Future research is recommended to develop and experimentally test scaffolding-based learning models that are aligned with APOS theory to enhance students’ higher-order thinking skills.
