Abstract

This research aims to determine the effect of the application of the co-op cop-op learning model on students' cognitive mathematics learning achievement in terms of emotional quotient in VIII class Junior High School 1 of Parungkuda. The population of this study are 298 students. The trial was given to 71 students, 35 students in the experimental class and 36 students in\ the control class. The sampling technique used in this research is simple random sampling. The instruments used in this research were subjective tests and emotional quotient questionnaires. The method of data analysis carried out in this study consisted of two methods, namely Two way Anova with unequal cell lines and a Likert scale to process questionnaire data. The results of the study show that there are differences in student achievement using the co-op co-op learning method and students who use the direct learning method. This shows that the researcher's hypothesis is acceptable. Students with high emotional intelligence and using co-op co-op learning models have the highest marginal values.

Abstract

The independent learning program focuses on how learning is free to innovate and improve literacy and numeracy skills. Both of these capabilities are still low in Indonesia. Literacy and numeracy skills are increasingly important in a digital environment, but it is challenging to develop approaches to learning a subject, for example, in calculus learning which is often considered rigid and traditional learning. This needs to be renewed using the concept of freedom of learning based on problem-posing and problem-solving. Calculus learning by involving both of these approaches will create democratic learning because the characteristic of this learning gives sovereignty to students to be independent in learning. Thus, students are free to think critically and creatively in finding information sources digitally and non-digitally as well as expressing their ideas on mathematical problems that exist in real life. Digital literacy and numeracy abilities of students will be formed, and the result of students will have four soft skills, namely, creativity, critical thinking, communication, and collaboration.

Abstract

Math learning has a finite amount of space and time. Where a junior high school math class in one grade is only a five-hour lesson with an hour lesson of only 40 menutes is considered insufficient. Apart from the lack of time for learning, there are a number of factors that are a barrier to math study, which is the influence of internal and external factor. On external factor such as the impact of the ingredients. Using a textbook is not enough for students to understand math lesson. For this reason research are trying to develop video-based teaching materials in hopes of overcoming space and time on learning. The learning video countains material discussions, examples of problems, discussion of examples problems, it’s been valeted by a material expert, so that the teaching materials developed by researchers can direct students to critical thinking. With the learning video, it is expected that students can learn anywhere and any time without the countraining of spcace and time. And the ultimate purpose of this video-based teaching development is to increase students critical thinking ability.

Abstract

The importance of creative thinking and collaboration so that every learning process must be able to develo those abilities. But students’ interest in math is so low that it’s hard to develop those abilities. One cause is lack of teaching material that can show students that math exists in their daily lives. The purpose of this research is developing and producing student workbook with Realistic Mathematic Education approach to student creative thinking and collaboration valid. Developing model that used in this research is ADDIE (Analysis, Design, Development, Implementation and Evaluation). The questionnaire tests of validity. Validity test result by validators was avowed very valid with percentage 90,1%. The result showed that student mathematic workbook with RME approach was valid and facilitating student creative thinking and collaboration.

Abstract

This study aims to see students' attitudes towards mathematics in third grade Public Elementary School students in Gunung Bahagia Village, Balikpapan. The subjects in this study were 174 students. Subject selection was done randomly. The technique of using data is by providing the first questionnaire to adapt from Tezer & Ozcan to a scale using facial expressions because students still have difficulty expressing attitudes in written form. The result of this research is that the general attitude of students towards mathematics is neutral, which means that they are normal towards mathematics.

Abstract

This study aims to describe the ability of mathematical problem solving in the SPLTV material in terms of multiple intelligence of class X MIPA students at SMAS Diponegoro Tumpang in the 2020/2021 academic year. The research method used in this research is descriptive qualitative. The subjects of this study were 6 students who were selected through the results of the multiple intelligence questionnaire, including 2 students who had mathematical logical intelligence, 2 students with intrapersonal intelligence, and 2 students with interpersonal intelligence. The techniques of data collection used in this study were multiple intelligence tests, mathematical problem solving tests, and interviews. Dominant research subjects with logical-mathematical intelligence have better skills in solving mathematical problems than other types of intelligence in solving mathematical problems and can practice concepts the concept algorithmically and present concepts in various mathematical representations. It is very important for educators to know and understand what kind of intelligences that students have. It is intended as a material for making lesson plans. So that the learning process can run smoothly, effectively, efficiently, and not only result-oriented.

Abstract

Studies that highlight the scope of mathematics learning still become continuous discussion topics. Numerous findings have the potential to be a discussion for further research. In mathematics learning, there are many problems in the form of mathematical errors made by learners in solving problems. This descriptive qualitative research aims to review mathematical errors made by students in Linear Algebra courses. Error analysis model using Kastolan stages that focus on 3 types of errors namely conceptual, procedural, and technical errors. A total of 30 students of Mathematics Education study program from Pelita Harapan University were given question to analyze their mistakes. Data analysis was performed using Miles and Huberman technique which included data collection, data presentation, and conclusion. The results showed that as many as 50% of students underwent conceptual errors, 20% of students underwent procedural errors, 3.33% of students underwent technical errors, and 26.67% of students underwent no errors. These findings provide an opportunity for researchers to analyze other mathematical learning with Kastolan stages as well as encourage researchers to develop learning models to minimize mathematical errors made by students.

Abstract

Learning mathematics online is a challenge for teachers considering that mathematics has abstract characteristics. Therefore, online learning needs to be designed to be effective. This study aims to evaluate online learning in the Mathematics Education Study Program using Importance Performance Analysis (IPA). Sampling was carried out using random sampling techniques in each batch of students of the Mathematics Education Study Program, PGRI Mahadewa University, Indonesia. Based on the results of the analysis and discussion, it was found that online lectures had gone according to student expectations. This is shown from the results of the IPA, namely that most of the indicators are in Quadrant I with the label "Keep Up the Good Work".
