Students Activities in Learning Pythagoras Theorems Using Desmos Application

Hilaria Yesieka Ayu Wulandari — 2024-03-01

This study aims to describe the creative thinking skills of students in solving problems related to the Pythagorean Theorem using Desmos application. This descriptive research involved 3 Junior High School students in grade 9 in Sidoarjo (Indonesia) who each had high, medium, and low ability backgrounds. The task in the form of questions consisted of two questions asking students to create two different triangles. The results of the analysis showed that high-ability students were able to create two different triangles if they were given sides 3 and 4 in the form of a right triangle and an equilateral triangle. Students with moderate and low abilities were able to draw right triangles with Desmos, but had difficulty drawing isosceles triangles. Both of them drew an isosceles triangle, but with side lengths of 3, 4, and 6. These results illustrate that the use of Desmos helps students' ideas in finding answers in drawing triangles, but the basic abilities that students have can be an obstacle in completing the given tasks.

Exploring Collaborative Problem Solving in STEM Contexts for Middle School Students

Tiara Rahma Putri Kusuma Dewi — 2024-03-15

In the 21st century, advances in science and technology require students to adapt. Classroom dynamics are still often dominated by passive learning methods, such as lectures, which result in a lack of student participation. PISA evaluation shows the low problems-solving abilities of Indonesian students. Therefore, the STEM approach emerged as a solution with a focus on essential 21st century skills, such as collaborative problem solving. The aim of the research is to investigate and analyze the collaborative problem solving process of junior high school students in solving STEM problems. The research method used is a case study with a qualitative approach. The research population included all students of SMP PGRI 13 Surabaya. Data collection techniques include observation, interviews, and questionnaires. Research instruments include questionnaires, observation sheets, and structured interviews. The research results show that collaborative learning in STEM context problem solving can help students develop problem solving skills. Students demonstrate good collaborative skills and their response to this learning is very positive. Evaluation of student learning outcomes also shows an increase, indicating the success of STEM-based learning methods in increasing student motivation. This research contributes to the understanding of the importance of learning approaches that integrate STEM with collaborative problem solving.

Students' Creative Thinking Process in Mathematic Problems Solving Assisted by GeoGebra

Ningrat Delvia Margaretha — 2024-03-28

The purpose of this research is to find out how students' creative thinking process in solving Geogebra-assisted math problems and to find out the obstacles experienced by students in the creative thinking process. This research is a qualitative descriptive research. The subject selection was taken 3 students using purposive sampling method, namely by considering students who were considered able to work on the math problems given and had been able to use GeoGebra. The data collection techniques used in this research were tests and interviews. The main instrument in this research is the researcher himself. Auxiliary instruments are math problems and interview guidelines. The math problem used is a spatial problem to find the volume and surface area with assisted by Geogebra to measure students' creative thinking. Interviews are used to find out how students' creative thinking processes while working on math problems. The analysis used is data reduction, data presentation and conclusion drawing. The results of this reasearch show the student’s creative thinking process in solving math problems assisted by Geogebra. In this reasearch also shows that students experience obstacles at the stage of synthesizing ideas, namely the stage of students gathering information or remembering and combining ideas sourced from previous experiences.

Analysis of students' difficulties in writing skills in English mathematics courses

Siti Zumrotul Ilmiyah — 2024-03-29

This research aims to analyze the difficulties faced by students in developing their writing skills in the Mathematics English course. Through a qualitative approach, this research explores the factors that influence student difficulties, including language aspects and mathematical concepts.. The research subjects taken were 5th semester mathematics education students. The data collection methods used were documentation methods, test methods, and observation methods. The documentation method was used to obtain data about the list of names of students who were used as research subjects. The test method is used to obtain data on student completion of English courses, the observation method is used to determine objective conditions during English teaching and learning activities and to determine factors that can influence the learning process. The location of students' difficulties in learning English lies in abilities including writing ability and listening ability. The difficulty of spelling errors is 30%, vocabulary errors are 40%, listening errors are 10%, and language errors are 20%. This shows that the level of student ability has a role in the student learning process and can be one of the factors that influence the level of student academic achievement.

Understanding of Student Self-Management in Mathematics Education at UNU Pasuruan

Titik Rachmawati — 2024-03-30

This research aims to understand how students manage time, plan, motivate, and respond to difficulties in the context of mathematics learning. The research methods used include surveys, interviews and documentation analysis. The research results show that students who are successful in learning mathematics tend to have better self-management skills. This research provides insight into the role of self-management in students' success in understanding mathematical concepts and provides a basis for developing learning strategies that can improve students' self-management skills. The conclusions of this research is provide a better understanding of the factors that influence the implementation of student self-management in the context of mathematics education, as well as providing direction for the development of more effective learning approaches.
