Abstract

The spread of the disease that occurs throughout the world, namely the Covid-19 pandemic, has made changes to learning methods. The learning method is now carried out with online learning, which previously used the face-to-face method. However, there are many shortcomings occurred when using online learning method. One thing that is most highlighted regarding the shortcomings of online learning is the inability of students to understand the material, including learning mathematics. This study used a qualitative approach with the aim of describing the effect of giving face-to face concept reinforcement via zoom meetings on the success of online learning. The research instrument was the researcher and the interview guideline sheet. The subjects of the research are the 3rd semester students of Tadris Matematika UIN STS Jambi in the academic year of 2020/2021. The results showed that strengthening the concept via zoom meetings could be done through systematic dialogue so that the concept can be fully understood. The dialogue is an open dialogue and is very dependent on the response of students. Face-to-face strengthening of concepts in online learning through systematic dialogue via zoom meetings is proven able to make students understand the concepts being taught even though learning is done with online learning.

Abstract

This research aims to describe secondary-level students' thinking processes in terms of their attitude toward mathematics in constructing proof by mathematical induction. This qualitative research involved two students who were selected from 30 students of second grade of senior high school that categorized into two groups, namely the students who have a positive and negative attitude toward mathematics by using Attitude Toward Mathematics Inventory (ATMI) questionnaire. One student from each category was selected to be given a proving test and interviewed. Students’ process of proving test and interview recording were collected and analyzed to identify their thinking process. This research points out that both students who have positive and negative attitudes towards mathematics can recall the information in their memory regarding the characteristics and steps to prove using mathematical induction. However, the student who has negative attitudes towards mathematics tends to experience some difficulties in processing information, especially in the induction step, caused by panic, depression, and insecurity. The student who has a positive attitude towards mathematics also experiences some difficulties in the proving process, namely understanding what to prove and compiling the induction steps. However, she keeps trying and believes that she would be able to solve it. Hence, she can solve the proof completely.

Abstract

Students abilities differ when given questions that require representing aspects to appear. This is because the ability of mathematical representation is influenced by the characteristics of the student way of thinking. The purpose of this study was to analyze the mathematical representation abilities of students in graph theory in terms of the characteristics of the way of thinking. This type of research uses qualitative research in the form of case studies. The research subjects were class B students in the sixth semester of IKIP PGRI Pontianak with one student taken for ways of thinking in Concrete Sequences (SK), Abstract Sequences (SA), Concrete Random (AK), and Abstract Random (AA) with selected using purposive sampling technique. The main instruments in this research is the researcher and the necessary supporting instruments include test questions on mathematical representation abilities, questionnaires on the characteristics of ways of thinking, and interview guidelines. To test the validity of the data used triangulation techniques. Data analysis was performed by data reduction, data presentation and conclusion. The results of the study showed that students with the SK and Sa way of thinking had fulfilled all the indicators of mathematical representation abilities, namely verbal, visual, and symbolic representations because their way of thinking was detailed and mastered the concept, while students with the AA and AK thinking only met the indicators of verbal representation due to the unstructured way of thinking and not mastering the concept.
