Abstract

The research purpose to describe and analyze the mathematical problem solving abilities of MTs students in solving Geometry Transformation problems through Online Learning due to the Covid-19 pandemic int Indonesia. The research method used is descriptive qualitative. The subjects of this research were 3 students of MTs Al-Hamid Class IX who were selected as representatives of the very good problem-solving ability category, the problem-solving ability level category was sufficient, and the problem-solving ability level category was lacking. The data collection technique used was a test consisting of 4 non-routine items and interviews. The results of the analysis can be obtained: (1) students with excellent problem-solving abilities are able to fulfill the 4 steps of solving according to their pattern but there are errors in understanding the problem in question 1. (2) students with sufficient problem-solving skills are only able to solve problems in question 1 and 2 while 3 and 4 there are errors in understanding the questions. (3) students with poor problem solving skills were only able to solve problems in question 2, while in questions 3,4 and 5 there were errors in understanding the questions. The student error factor is due to the lack of understanding of the concept of geometric transformation to do the test because the geometric transformation test questions given are non-routine, while the geometric transformations that are often encountered only substitute formulas without understanding the concept of geometric transformation which includes translation, reflection, rotation and dilation. Many have to do with everyday life so that students experience difficulties in what is meant in the questions, especially in questions 3 and 4.

Abstract

Elementary school students generally consider mathematics learning difficult, especially in the matter of multiplication, so a method is needed to develop and improve mathematical calculation skills. One method that can be used is the cross line method. This research aims to improve the ability to calculate multiplication using the cross line method. This type of research is Classroom Action Research (CAR) with the subject of research on third grade students of SD Negeri 9 Tanrutedong, South Sulawesi. Techniques of data collection were test and observation. The instruments used were test sheets and observation sheets. The collected data were analyzed using descriptive statistics. The results showed that the use of the cross line method could improve students' ability to calculate multiplication. This is indicated by the increase in: (1) The average score of the ability to count in the first cycle of 67.39 increased in the second cycle to 92.00, (2) The achievement of student learning completeness from the first cycle of 65.22% increased in the second cycle to 100%, and (3) the increase in the average percentage of student activity in the learning process by 77.78% in the first cycle to 94.68% in the second cycle

Abstract

This study aims to estimate the difficulty level of high-level reasoning math problems by comparing the estimated difficulty level of the Focus Group Discussion (FGD) approach and the Iteman program. The estimation of the FGD approach uses a semantic differential scale on a scale of 1-7, while the Iteman program uses version 4.0. The study used a quantitative-comparative approach involving 79 FGDs of students and teachers of SMP/MTs in Soppeng Regency. Each FGD consisted of four people, one teacher and three students of class VIII. The comparative of difficulty level using Scheffe test with a significance level of 0.05. The results showed that the average level of difficulty in the FGD approach had significant similarity with the average level of difficulty in the output of the Iteman program approach. This means that the estimated level of difficulty of the FGD examinees has a similarity with the output of the Iteman program from the response data of the FGD examinees. This shows that examinees  from FGD in assessing the level of difficulty of high-level reasoning questions can be the teacher’s choice in schools other than the Iteman program.

Abstract

Difficulties in learning mathematics can be experienced by students with any level of ability from any circle or group. With the students' learning difficulties in mathematics, the question arises why this can happen and as educators, what is the teacher's perception of learning difficulties in mathematics. The purpose of this study was to describe Teacher's Perception of Students' Mathematics Learning Difficulties. This research used a descriptive qualitative approach with non-test data collection techniques through questionnaires and interviews. The results showed that: (i) the mathematics teacher's perception of the dominant causes of learning difficulties revealed psychological causes, including low interest or motivation and understanding of basic concepts as the cause of students' mathematics learning difficulties; (ii) the mathematics teacher's perception of the symptoms that are indicators of learning difficulties in mathematics, the most widely disclosed is the low ability of students to complete the tasks given by the teacher; (iii) the teacher's perception of the method used to investigate the existence of difficulties in learning mathematics, the most commonly done is through observation, interviews and documentation by looking at the results of tests or assignments of each student; (iv) the teacher's perception of examples of difficulties experienced by students in learning mathematics, which is widely revealed in the competency standard for understanding the properties of arithmetic operations and their use in problem solving being taught; and (v) teachers' perceptions of the efforts made to overcome students' mathematics learning difficulties vary according to their respective experiences. There are only a few teachers who do group guidance and individual guidance.

Abstract

This study aims to describe the application of the cooperative learning model of the Team Assisted Individualization (TAI) type assisted by manipulative learning media to improve student learning outcomes in shape material. This study involved 29 elementary grade VI students as a research sample and used a pre-experimental research type with a one-group pretest-posttest design. Student mathematics learning outcomes data obtained from student learning outcomes tests consisting of 10 breakdown questions and analyzed using descriptive and inferential analysis. To see an increase in student mathematics learning outcomes can be interpreted using normalized gain (N-gain). From the results of data analysis, it is obtained that: (1) the average value of student learning outcomes before applying the TAI learning model assisted by manipulative media is 42.21 with a low category; (2) the average value of learning outcomes after applying the TAI learning model assisted by manipulative media is 74.76 with a high category; (3) hypothesis test results obtained tcount> t table (13,589> 2,048) and the significance value is 0,000 <0.05 so that Ha (Ha: µ1 <µ2) is accepted; (4) increase in the value of pretest and posttest with gain index (d) of 0.56 with the medium category. Thus, it can be concluded that the application of the cooperative learning model of the TAI type can improve the learning outcomes of elementary school students in grade VI in shape material. Therefore, this type of TAI cooperative learning model can be used as an alternative learning model that can be used in order to improve student learning outcomes
