Abstract

The research aimed to improve activity and learning achievement of the students on Polynomial learning at class XI MS 4 SMA Negeri 1 Narmada in academic year 2018/2019 by application of cooperative learing type Numbered Heads Together. The type of this research was a classroom action researc was conducted in two cycles. Each cycle contained planning, implementation, observation, evaluation, and reflection. The result showed that the activity score of students in cycle I meeting one is 8 with the least active category and meeting dua is 11.99 with active categories, in cycle II meeting one is 13.33 with the category of activity and meeting two which is 14,66 with a very active category. For the average value of student learning achievement in cycle I, cycle II, it was 69.67 and 78.70 with classical completeness respectively 60.00%, and 92.50%. It can be concluded that this researchby application of cooperative learning type Numbered Heads Together can improve the activity and learning achievement on Polynomial learning at class XI MS 4 SMA Negeri 1 Narmada in academic year 2018/2019.

Abstract

This study aims to describe students' creative thinking skills in solving problems Pythagorean Theorem in terms of the learning style of class VIII students of SMPN 1 Taliwang, with the type of the research used is descriptive research. The research instrument used is a questionnaire, creative thinking skills test and interviews. The sampling that used in this study is purposive sampling technique so that the samples were students of class VIII-5 and VIII-7 SMPN 1 Taliwang in the academic year 2021/2022 which consists of 59 students who were then given learning style questionnaire obtained two students with visual learning styles, two students with auditory learning styles and two students with kinesthetic learning styles who were then given a creative thinking ability test and Interview. The results showed that subjects with visual learning styles had the ability to creative thinking which is in the category of creative enough, by meeting the indicators of fluency and flexibility with percentage respectively 100% and 50% but have not been able to meet the indicators of novelty with percentage 8%. Subjects with auditory learning style have the ability to think creative who are in the category of quite creative, by meeting the indicators of fleksibility dan fluency with percentage respectively 75% and 79% but have not been able to meet the indicators of novelty with percentage 4%. Subjects with kinesthetic learning styles have the ability to think creatively in the less creative category, by meeting the fluency indicator with a percentage of 100%, and not yet able to meet the flexibility indicator with a percentage of 0%, and the novelty indicator with percentage of 12.5%.

Abstract

This study aims to describe the types and causes of student errors in solving algebraic problems in terms of learning styles. Analysis of student errors using Newman's error procedure. This type of research is descriptive qualitative research. The initial subjects in this study were students of class VIIA and VIIB SMPN 2 Pringgarata in the 2025/2026 academic year and the final subjects were 10 students selected based on their learning style type by looking at their dominant learning style. The instruments used were (i) Learning style questionnaire, used to determine the type of student learning style, (ii) Written test, used to find the type of student errors using Newman's error procedure, (iii) Interview, used to find the causes of student errors in solving problems. The data analysis techniques used were data reduction, data presentation, and drawing conclusions. The results of this study were 10 selected subjects, namely 5 students with visual learning style types, 2 students with auditory learning style types and 3 students with kinesthetic learning style types. Students with visual learning styles tend to make mistakes at the process skills and conclusion writing stages, the cause of these mistakes is because they do not know the right steps to solve the problem, are in a hurry so they forget to write the conclusion. Students with auditory learning styles tend to make mistakes at the transformation, process skills and conclusion writing stages, the cause of these mistakes is because they do not know how to make mathematical equations and models, do not know what formulas to use and do not know the steps to solve the problem. Students with kinesthetic learning styles tend to make mistakes at the reading, understanding, process skills and conclusion writing stages, the cause of these mistakes is because students are unable to understand the meaning of the problem correctly, are unable to find the steps to solve the problem correctly, rewrite previous mistakes at the conclusion writing stage and even do not know what to write at the conclusion writing stage.
