Triangel Concept Learning Design Using Palembang Cultural for Class VII Students
No full textThe triangle is still a topic worth discussing because many pupils still want assistance in comprehending the notion of triangles as a whole. The research aims to produce a triangular concept learning design using the Palembang cultural context for VII grade students with augmented reality technology. The research subjects comprised 19 students from Class VII of Al-Azhar 33 Islamic Middle School in Palembang. The method used is design research, divided into preparing for the experiment, and design experiment, divided into two cycles, namely pilot experiments and teaching experiments, and finally, retrospective analysis. The data in this research was collected by observation, interview, documentation, and test. The instruments used in this research are video and field notes for observation and interview, LAS for documentation, and post-test for test. The data analysis technique is descriptive qualitative. The final result of this study is Local Instruction Theory (LIT) which contains the learning process in 4 activities, namely describing the triangles of the Musi 6 Bridge, identifying the properties of triangles based on side lengths, identifying the properties of triangles based on the size of the angles and solving problems related to the properties of triangles based on the length of the sides and the size of the angles. The results show that the cultural defined context can be used as a reference point in triangle material in class VII SMP.This research was carried out with the aim of producing a triangular concept learning design using the Palembang cultural context for class VII students with augmented reality technology.

Implementation of the connected mathematics project learning model on students\u27 mathematical critical thinking ability
Full text linkStudents\u27 low critical thinking ability in learning mathematics is a major problem in research. This needs to be overcome by implementing learning that provides opportunities for students to develop their thinking ability rationally and well-structured in learning mathematics. One learning model that supports this learning is the Connected Mathematics Project (CMP) learning model. This study aimed to describe quantitatively the implementation of the CMP learning model on students\u27 critical thinking ability in mathematics. This type of research is quasi-experimental with a one-group pre-test and post-test post-test design. The research instruments were observation sheets and tests. The results showed that the application of learning observed in 4 meetings in terms of 9 student activities in learning in the sample group met the criteria for being effective. The student\u27s critical thinking ability through the paired t-test showed a significance value of 0.00, which was smaller than the alpha level of 0.05, meaning that there was a significant difference in the average score from the pre-test to the post-test. Furthermore, the n-gain value obtained is 0.36 (medium). Thus, it was concluded that implementing CMP learning on students\u27 critical thinking ability was effective.Rendahnya kemampuan berpikir kritis siswa dalam pembelajaran matematika merupakan masalah utama dalam penelitian.
