Abstract

The purpose of this study was to describe the Application of the Team Assisted Individualization (TAI) Type of Cooperative Learning Model which can improve the Mathematics Learning Outcomes of Class VII MTs Politani Maccirinnae Tikke in material on Algebraic Operations. The research subjects were 30 students of class VII, consisting of 11 male students and 19 female students, and three students were selected as informants. This research was conducted in two cycles. The results showed that the application of the TAI-type cooperative learning model could improve student learning outcomes in material for algebraic operations in class VII MTs Politani Maccirinnae Tikke by following the phases of cooperative learning, namely: at the first meeting 1) conveying goals and motivating students, the teacher conveys material and learning objectives and motivate students to be enthusiastic and actively involved in learning. Next, provide apperception by reminding the material previously studied, 2) present information, the teacher briefly describes the phases of the TAI type cooperative learning model that will be applied in learning, then the teacher distributes worksheets to be worked on individually, 3) organizes students into groups -study groups, the teacher divides students into 5 study groups (Teams), 4) guides the work and study groups, the teacher gives new LKPD to each group and conveys that individual work results are discussed in groups. The results of the discussion are concluded in the answers to the LKPD (Team Study), 5) Evaluation, the teacher appoints groups in turn to present the results of their group discussions (Whole Class Unit), 6) gives awards, the teacher announces the best group from group learning results and gives awards in the form of applause (Team Score and Team Recognition), and at the second meeting the teacher gave a final action test (Fact Test). This is indicated by the percentage of students' classical completeness in cycle I of 57.14% increasing to 80.76% in cycle II. The results of observations of teacher activity in cycle I were in the good category with a total score of 37 and an increase in cycle II was in the very good category with a total score of 45. The results of observations of student activity in cycle I were in the good category with a total score of 36 and an increase in cycle II is in the very good category with a total score of 45.

Abstract

The objectives of this study are: (1) To describe the analogical reasoning of class XI MAN 1 Poso students in the material of geometric sequences from field independent cognitive style and field dependent cognitive style. This type of research is descriptive research using a qualitative approach. The subjects in this study were two students of class XI MIPA MAN 1 Poso even semester 2021/2022 consisting of one RM student with FI cognitive style and one FN student with FD cognitive style. The students' cognitive style data was obtained by giving the GEFT test, while the students' analogy reasoning data were collected from the analogy reasoning test and interviews. The results of this study indicate that (1) field independent cognitive style students' RM fulfills all stages in each indicator of analogical reasoning and can explain the analogy used, namely in the source and target problems there are similarities or analogies in the solution, namely using the nth term formula. in the geometric sequence, namely  so it is included in high analogical reasoning. (2) While the field dependent cognitive style students' FN tend to be less able to fulfill all stages of each indicator of analogical reasoning. At the applying stage, FN has not been able to apply the relational structure of the source problem in solving the target problem, and tends not to be able to explain the analogy used. because it can't explain the analogy used so FN is included in moderate analogy reasoning.

Abstract

The purpose of this study was to describe of errors made by student in class XI MIA 1 Madrasah Aliyah Al-khairaat kalangkangan in solving narrative questions on arithmetic sequences and series based on newman’s stages. This type of research is descriptive using a qualitative approach. Subjects were 2 students drawn from 36 class XI MIA 1. The results of this study were (1) no reading error made by the subjects as they able to read out the questions given very well. (2) no of the subjects made a comprehension error, this could be seen during the interview, all research subjects were able to provide known and asked information from the questions. (3) Transformation errors were made by all research subjects. This transformation error is characterized by the subject failing to change the problem into the correct mathematical model and the subject being wrong in determining the formula to be used to solve the problem. (4) Process skill errors were made by all research subjects, this was indicated by the subject knowing the steps to solve the problem but was wrong due to the subject's error at the transformation stage and the subject could not carry out the mathematical calculation process correctly. (5) errors in writing the encoding error were made by all research subjects, this was indicated by the subject not determining the final result of the answer and the subject being wrong in determining the correct answer due to errors made in the previous stage.
