Abstract

TThis study aims to create a problem-solving based learning path for exponential material using the context of worm growth and to determine the effectiveness of this problem-solving based learning path for exponential material utilizing the context of worm growth. Exponential material is often considered difficult by students, so we must be able to create an interesting learning path to assist students in problem-solving, one of which is the PMRI approach. The worms' growth and reproduction process illustrates the exponential concept with an exponential regeneration and growth cycle. This study consists of four activities: (1) Understanding the problem, (2) Developing a plan, (3) Implementing the plan, and (4) Re-examining. The method used in this study is the design research method of the validation study type, which consists of three stages: preparation and design, design experiment, and retrospective analysis. Data collection techniques in this study used observation techniques, interviews, student work results, and pretests/posttests. The results of this study are learning paths designed to provide in-depth conceptual understanding for students and become solutions in problem-solving, especially in exponential material.

Abstract

Collaboration and creative mathematical thinking are important for students. However, students' collaboration and creative mathematical thinking skills are still low because students are not used to collaborating or investigating the problem-solving process. This research aims to determine students' collaboration and creative mathematical thinking skills in the 10th grade in Problem-Based Learning using numeracy problems. This research was carried out on 25 vocational school students majoring in accounting in Palembang, Indonesia. The research method used was a mixed method. The results of research on students' collaboration skills show that most of the students are in the excellent category. Students can fulfill respect for others and commitment indicators, but the indicators of deliberation and participation are rarely fulfilled. The research results on students' creative mathematical thinking skills show that 80% are in the very good category, 16% are in the good category, and others are in the pretty good category. Students can fulfill three indicators, fluency, originality, and elaboration, but flexibility is rarely fulfilled. Creative thinking skills of students need to improve.

Abstract

This study is motivated by students’ low conceptual understanding and spatial reasoning in rotation, as well as the limited integration of local cultural contexts with digital technology in mathematics learning. It aims to design and validate a PMRI-based Hypothetical Learning Trajectory (HLT) integrating Songket Mak Raje and Desmos to develop students’ conceptual understanding and spatial reasoning on rotation. The study employs a design research method of the validation study type, involving 6 students in the pilot experiment and 36 students in the teaching experiment. The main instrument is a Desmos-based E-LAS. Data were collected through observation, interviews, and analysis of students’ work documents and analyzed qualitatively using thematic and retrospective approaches. The results show that the developed HLT is valid and effective in developing students’ conceptual understanding and spatial reasoning. Retrospective analysis produced a Local Instructional Theory (LIT) as a refinement of the HLT, emphasizing gradual scaffolding, explicit articulation of rotation properties through guided inquiry before formal generalization, and early introduction of non-contextual problems with geometric constraints to foster spatial reasoning. This study implies a model for integrating ethnomathematics and digital technology, a PMRI-based LIT as a guide for instructional design, and a practical and validated Desmos-based E-LAS prototype.
