Abstract

Student learning achievement in Indonesia is low, this is because there are still many students who experience difficulties in learning geometry. To overcome these problems a way is needed so that students can understand concepts meaningfully and have good geometrical reasoning. This is certainly related to the appropriate learning model to be used in the learning process. One model of learning that can be used is a problem-based learning model. The purpose of this study is to describe the ability to understand the concepts and geometric reasoning of students who acquired a problem-based learning model compared with students who received conventional learning on quadrilateral material in class VII MTs. Tanwiriyah Kalisari. The research method used is quantitative with quasi-experimental research design. The results of the study showed that the ability to understand the concept of students who obtained a problem-based learning model was better than the ability to understand the concept of students who obtained conventional learning models. as well as the geometric reasoning abilities of students who acquired a better masculine learning model compared to the geometric reasoning abilities of students who acquired the conventional learning model.

Abstract

This study aims to describe the use of dynamic geometry software (DGS) by mathematics teachers in their teaching and learning activities. This study case involves two junior high school mathematics teachers who use DGS in their teaching activities. The data of this study were collected by recording teacher activity and interviewing the teachers. The data were then analyzed through data transcription, data categorization, data reduction, data review and analysis, and conclusion. The results of this study involved, first, the use of DGS in teaching and learning activities can be categorized into two activities: 1) shifting and 2) delivering content. The delivering content is later divided into two activities: a) applying representation and b) modeling. Shifting activity occurred when teachers had an interval period while conducting one activity to another. Delivering content-applying representation activity occurred when teachers were using DGS to deliver both conceptual and procedural materials to the students. Delivering content-modeling activity occurred when teachers were using DGS to make students acquire knowledge and have a problem-solving skill as performed by their teachers. The modeling activities occurred either explicitly and implicitly.

Abstract

One of the cognitive skills that students must have is problem-solving ability. Therefore, a standardized test is needed to measure this ability. However, until now, the tests used to measure mathematical problem-solving ability were not standardized. This research aims to develop a valid and practical mathematical problem-solving test in the discussion of triangles and rectangles. This research is part of the RD 4D type with steps: Defined (analysis to develop a test), Design (designing a problem-solving test form), and Develop (expert judgment and small group trials). The instrument in this research was the validation sheet used by the validator to assess each test item. The data analysis technique used the Aiken method for expert judgment and qualitative descriptive for development testing. The result is a valid and practical mathematical problem-solving test because the V-Aiken value is more than 0.532. Based on this, the instrument can be used to measure the mathematical problem-solving ability of junior high school students in the discussion of triangles and rectangles.

Abstract

This study aims to identify teachers' practices and barriers in carrying out a cognitive mathematics assessment during the COVID-19 pandemic. The type of research used is an online survey using a google form, which is spread over ten days via WhatsApp. This survey uses a qualitative approach. The research instrument was constructed from a pocketbook of periodic diagnostic assessment. A total of 78 primary to secondary school teachers from various regions in Indonesia participated. Data analysis was done descriptively, while data from open questions were analyzed using Atlasti 9. The study results present the practice of cognitive assessment regularly carried out by online-based mathematics teachers in high-grade elementary schools to secondary schools. In contrast, low-grade elementary schools are conducted by home visit. In practice, teachers experience several obstacles: the validity of the answers, limited time in the assessment, barriers from students themselves, and facilities. These obstacles cause the assessment results not to describe the cognitive level in-depth or provide valid and reliable information regarding students' achievement.

Abstract

This study aims to analyse the gender issue presented in pre-service elementary teacher-designed mathematics picture books (BBM). Thirteen BBMs are analysed based on male and female characters presented in the titles, pictures in the cover, main characters, and a number of pictures, conversations, and words in book contents. The findings show that the male characters are presented 1.79 times more often than the female characters. The numbers of pictures, conversations, and words in the book contents for males is 1.79; 1.99; and 1.79 consecutively times more often than the female characters. Meanwhile, each of the two BBMs presents only male or female characters. The implications of this study indicate that gender is still an important issue in BBM being developed.
