The main purpose of this study is to explore the extent to which van Hiele's theory can be used as a theoretical framework for technology-assisted geometry learning. Geometry learning in question is learning flat-sided geometry in junior high school. Technology-assisted geometry learning is viewed from various perspectives, including didactic situation theory, learning trajectories, learning barriers, and van Hiele's theory. The results of the study show that: 1) All of the students' books being studied need to consider the content aspect from the van Hiele theory perspective; 2) the implementation of technology-assisted geometry learning must pay attention to a series of didactic situations so that gaps in knowledge are revealed that interfere with the learning flow and create student difficulties.

The purpose of this study was to describe the difficulties of students as prospective Mathematics teachers in designing inductive learning. This study uses a qualitative approach. The type of this research is a case study. The research subject was 1 student of the Tadris Mathematics Study Program, Salatiga State Islamic Institute as a prospective mathematics teacher. Data were collected through observation, document analysis, and interviews. Validation of the validity of the data is done through technical triangulation. The results showed that 1) students had difficulty in understanding the inductive learning paradigm; 2) students have difficulty in describing the inductive approach to learning mathematics.

The aim of this research is to produce an Android-based learning module on the material of flat face three dimensional objects. The type of this research is design research by applying ADDIE development model with five development steps, namely analysis, design, development, implementation, and evaluation. The result of this research is an Android-based learning module application which contain of materials, evaluations, and geometry puzzle games menu. The validation result of the android-based learning module that conducting by 6 expert reviewers that consist of 2 material experts, 2 media experts, and 2 user experts were showed valid without revision predicates. The product has been implemented at SMPN 2 Mantup, Lamongan involved 64 students divided into experiment and control class. Based on the results of student response questionnaires, the use of Android-based learning modules is able to increase learning motivation and make them easier to understand Mathematical concepts. The products also have been proven to be effective in improving students' understanding of Mathematical concept based on the average N-Gain score of 61.19% which included in the middle category. The results of Mann-Whitney test also showed that the average score of students' Mathematical concept understanding in the experiment class is significantly higher than control class.

The aim is to obtain qualitative results of the growth of the Problem Solving Process for JHS/SMP students throughthe online Mathematical Connection problems. The research method, with the Mixed Method. In the quantitative approach, the population is grade IX students of SMP at Semarang. The research subjects for this qualitative approach, took 6 students of Grade 9 of SMP at Semarang. Data analysis using t-test, followed by data reduction, data exposure, data interpretation, and conclusions. The main activities are: (1) providing mathematical connection problems by online, (2) conducting t-tests, (3) conducting qualitative analysis, and (4) conclusions. The result, there is a growth in the Problem Solving Process of SMP Students through Mathematical Connection problems online. In the research subject, there are 1 student in the Very Good category, 4 students in the Good category, and 1 student in the Moderate category. [ABSTRACT FROM AUTHOR]

The aim is to examine the findings of Assistive Technology in Sign Language for Mathematical Lecture in Inclusive Class. The method is a mixed method that combines quantitative and qualitative approaches. The stages of the activity are: (1) Analyzing mathematical lecture material that is made in PPt with the voice of the lecturer which will later make a Assistive Technology Video. (2) Make a companion video with Sign Language based on the lecturer's Narrative Video. (3) Merging to integrate the PPt video of the lecturer's narration with the video of Sign Language. (4) Implementing the use of Assistive Technology in Sign Language for Mathematical Lecture in Inclusive Class. (5) Conduct of qualitative tests to test the effectiveness of the use of Assistive Technology. As a results, (1) Sign Language Assistive Technology was found that can be applied and integrated in Mathematics Lectures in Inclusive Class in the Information System Study Program. (2) Assistive Technology in Sign Language for Mathematical Lecture is effective to be applied in the Inclusive Class. [ABSTRACT FROM AUTHOR]

The aim of this study was to describe students' mathematical problem-solving abilities. This research is a qualitative descriptive study. The population in this study were all students of class XI SMA Negeri 26 Riau Islands academic year 2020/2021. The sample in this study were XI IPS 1. The technique of collecting data consisted of mathematical problem-solving ability test and documentation. The data were analyzed using descriptive. The results showed that students who had high problem-solving abilities were 2 students, students who had moderate abilities were 13 students, students who had low abilities were 6 students. 64% of students were able to solve problems at the stage of understanding the problem, 61% of students were able to devise a plan, 57% of students were able to carry out the plan, and 56% of students were able to look back.

This study aims to analyze students' numeracy literacy skills based on emotional intelligence in learning mathematics and gender for class VIII in the academic year 2020-2021. The research method used is a qualitative research method with a qualitative descriptive research design. The subjects of this research are students of class VIII-8 SMPN 32 Jakarta. The instruments used are questionnaires, tests and interviews. Data analysis was carried out with data reduction techniques, data presentation and conclusion drawing. Checking the validity of the data in this study was carried out through a credibility test which included triangulation of sources, techniques and time. Before conducting the research, the researcher tested the validity and reliability of the instruments used. The results of the study concluded that: (1) students' numeracy literacy skills based on high and moderate emotional intelligence reached all four indicators or all indicators that had been determined. This is because students' answers in general can write and answer things related to each of the indicators of this research. (2) the numeracy literacy ability of students with low emotional intelligence only reached 1-2 indicators of the 4 indicators found in this study. This is because students with low emotional intelligence are often less able to write and answer matters relating to each of the indicators contained in this study. [ABSTRACT FROM AUTHOR]
