The ability of geometry is an aspect that underlies students to solve geometry problems. Several studies have stated students' difficulties in learning geometry. There are five levels of expansion of Van Hiele's theory, namely level 0, level 0.5, level 1, level 1.5, and level 2 which are used to measure the geometry abilities of junior high school students. Students' low geometry skills can be improved through scaffolding, so an appropriate scaffolding design is needed. This study aims to describe the appropriate scaffolding design based on the geometry ability test of junior high school students in terms of the expansion of Van Hiele's theory. The research subjects in this study consisted of 3 students of class VIII of SMP Negeri 8 Malang divided into 3 different levels of geometry ability, namely level 0, 0.5, and 1. Data collection methods consisted of written tests and interviews. The results showed that students at level 1 needed scaffolding to be able to connect the properties between quadrilateral shapes. Students at level 0.5 require scaffolding in the form of conceptual understanding of prerequisite materials. While students at level 0 need scaffolding to minimize the prototype phenomenon.

The lecture on algebra has not involved students in working together. Thus, one effort that can be done is implementing the jigsaw cooperative learning model. This study aims to describe the student collaboration activities in the introduction to algebra course using the jigsaw cooperative learning. This research is a quantitative descriptive study. The subjects were 32 first semester students of 2019 who were enrolled in the introduction to algebra course in the Mathematics Education Study Program, FMIPA, Universitas Negeri Malang. The instrument in this study was an observation sheet of student activities, and the supporting data were the results of individual exercises. Data were analyzed descriptively. The results showed that student collaboration activities in the jigsaw cooperative learning in the introduction to algebra course were very good, as indicated by the average score of students in completing individual exercise problems was 90. Thus, it can be concluded that the selection of an appropriate learning model can enhance student collaboration in learning abstract mathematical concepts.

Mathematical literacy is the ability of students to carry out activities formulate, apply, and interpret & evaluate mathematics in various contexts. This study aims to analyze the needs of student worksheet development which can stimulate students' mathematical literacy. This type of research is a qualitative descriptive study involving 15 students of class XI MIPA and 2 mathematics teachers of SMA Negeri 1 Gresik. This needs analysis includes material analysis, curriculum analysis, and student analysis. The results showed that one of the difficult mathematics materials for class XI MIPA was linear program, mathematics learning was carried out according to the 2013 Curriculum with the application of Blended Learning in the new normal era, and students still had difficulty solving problems on indicators of interpreting & evaluating mathematical process abilities. Therefore, Student Worksheet based Blended Learning will be developed which is more focused on activities that prioritize the interpretation and analysis of problem solving results according to the limitations and context of the problem in the Linear Program material.

The research aims at exploring the characteristics of ‘don’t need’ boundaries of students in solving arithmagon problems using qualitative descriptive approach. The participants win this research are 23 eight-grader junior high school students. The research used the instruments including test questions and unstructured interviews. The data collection procedure began with giving test questions to 23 participants. All of them could make mathematical diagrams/drawings/model precisely according to the information presented from the problem. The student who used effective and clear sentences in solving problems though could not solve the problem in a structured manner is called as Subject 1 (S1). The student who did not use effective and clear structured sentences is called as Subject 2 (S2). The student who used effective and clear sentences as well as structured in solving problems is called Subject 3 (S3). This research used triangulation method by exploring data obtained from the test and interview results. According to the research result, it is concluded that S1 crossed the first ‘don’t need’ boundaries when solving the addition and multiplication arithmagon problems. S2 crossed the first and second “don’t need” boundaries when solving addition arithmagon problem and only crossed the first ‘don’t need’ boundaries in solving multiplication arithmagon problems. However, S3 crossed the second ‘don’t need’ boundaries in solving arithmagon problem of addition and multiplication. Through this research, it is hoped that further research will be able to find and explore the third ‘don’t need’ boundaries in solving mathematical problems.
