Abstract

Masalah utama dalam penelitian ini yaitu rendahnya hasil belajar siswa pada materi komposisi dua fungsi hal ini disebabkan karena siswa kurang memahami konsep dalam menentukan komposisi dua fungsi, sehingga siswa mudah lupa dengan rumus menentukan komposisi dua fungsi. Selain itu, kurangnya pemahaman siswa pada materi prasyarat dari materi komposisi dua fungsi, yaitu materi tentang aljabar fungsi, serta sebagian besar siswa kurang aktif selama mengikuti pembelajaran. Tujuan penelitian ini adalah untuk memperoleh deskripsi tentang penerapan model pembelajaran kooperatif tipe TPS yang dapat meningkatkan hasil belajarar siswa pada materi komposisi dua fungsi di kelas X IPA 5 SMA Negeri 7 Palu tahun ajaran 2018/2019 berjumlah 33 orang siswa yang terdiri dari 14 laki-laki dan 19 perempuan. Jenis penelitian ini adalah penelitian tindakan kelas. Desain penelitian mengacu pada model Kemmis dan Mc. Taggart yang terdiri dari empat komponen, yaitu (1) perencanaan, (2) pelaksanaan tindakan, (3) observasi dan (4) refleksi. Penelitian ini dilakukan dalam dua siklus. Data Hasil penelitian menunjukan pada tes akhir siklus I terdapat 15 siswa tuntas dan 17 siswa tidak tuntas berikut ketuntasan belajar klasikal mencapai 46,87%, Sedangkan pada siklus II terdapat 26 siswa tuntas dan 5 siswa tidak tuntas berikut ketuntasan belajar klasikal mencapai 83,85%. Jadi dapat disimpulkan bahwa penerepan model pembelajaran kooperatif tipe Think Pair Share dapat meningkatkan hasil belajar siswa kelas X IPA 5 SMA Negeri 7 Palu pada materi komposisi dua fungsi, dengan tahapannya yaitu (1) pendahuluan, (2) think, (3) pair, (3) share, dan (5) penghargaan.

Abstract

This research aims to determine whether there are differences in student mathematics learning outcomes between offline and online learning at SMP Negeri 2 Palu. The research used a comparative method with a population of all students in class VIII, totalling 332 students. The sample was class VIII students who did offline and online learning, with different samples but the same abilities. The sampling technique is Purposive Sampling. The researchers took 60 samples consisting of 30 students each from classes A and B. The data collection technique was carried out by taking the even semester midterm test scores for the 2021/2022 academic year obtained by students during online learning and the even semester midterm test scores for the 2022/2023 academic year obtained by students during offline learning, with the same subject matter, namely the Pythagorean theorem. Provided that the material taught is equivalent during offline and online learning and has the same academic abilities: (1). Mathematics learning outcomes obtained an average score of 64.13 and 68.27 (2). Sig value. (2-tailed) 0.187 > 0.05. This means that H0 is accepted, and Ha is rejected. So, the research results show no difference in student mathematicslearning outcomes between offline and online learning.

Abstract

This study aims to Getting a description of errors and factors that cause errors in doing UAS for grade VIII students of SMPN 2 Galang, knowing the teachings of 2023-2024. This research is a descriptiveresearch with a qualitative approach. The subject of this study is to take 12 students of grade VIII SMP N 2 GALANG based on the value of UAS results under the KKM and teacher recommendations that can represent the answers of other students' mistakes. The researcher selects the subject by looking at the results of the student's final semester exam. Values that are below the MMC (minimum completeness criteria) will be analyzed for errors. The standard of KKM scores set at school is 75, so that students' UAS scores that are less than 75 are analyzed for errors. The results of this study show the types of mistakes made by grade VIII students of SMP N 2 Galang based on Newman's procedure: (1) errors in understanding. (2) errors in transforming, (3) errors in process skills, and (4) errors in writing the final answer. Factors that cause errors: (1) lack of students' understanding of the material that has been taught. (2) mastery of basic mathematical skills in the form of weak mathematical computing. (3) lack of understanding of concepts that make students easily forget the material that has been learned. (4) the learning model is not optimal, so that students still have difficulties in learning mathematics and tend to consider mathematics as a difficult and confusing subject.

Abstract

This study aims to longitudinally describe the metacognitive skills and external representation in the context of problem-solving at Chemistry Education, Tadulako University. The qualitative study respondents were selected from a number of first year students for two consecutive semesters. Two respondents were selected based on results of selection using a metacognitive skills assessment questionnaire (MCAI) and we categorized as high and medium. Three problems were resolved by respondents at intervals of one to two weeks in each semester through a one-on-one thinking aloud and it was followed by a semi-structured interview. Data collection was recorded using a video camera. Metacognitive skills and external representation data from the odd and even semesters were deeply analyzed. This analysis technique was carried out by examining the results of problem solving and semi-structured interviews in detail and matching them with the indicators of metacogni-tive skills and external representation used by both respondents. The data analysis results showed that the thinking ability of respondents with high metacognitive skills in problem solving, experienced developments over time along with the development of their cognitive regulation and external representation. On the other hand, respondents with intermediate metacognitive skills during problem solving, were relatively the same for two consecutive semesters. Therefore, teachers need to consider the use of learning strategies by taking into account the number of students who have dominant characteristics in classroom learning, in terms of metacog-nitive skills and external representation.

Abstract

The purpose of this study is to explore the implementation of Science, Technology, Engineering, Arts, and Mathematics (STEAM) within a problem-based learning (PBL) approach to enhance students' creativity and learning outcomes in science subjects at SD Inpres Tanamodindi. The research was conducted in Grade V of SD Inpres 1 Tanamodindi Palu, where students exhibit diverse academic abilities. Following the research design proposed by Kemmis and McTaggart (2013) and Zhong, Y. (2024), the study was carried out in two cycles. Data collection methods included observations, interviews, field notes, and learning outcome assessments. The findings reveal that integrating the STEAM approach into the PBL model at SD Inpres Tanamodindi led to an improvement in learning outcomes, rising from 64.65 in the first cycle to 71.77 in the second cycle. Additionally, students' creativity in solving science-related problems improved, progressing from the "sufficient" category in cycle 1 to the "very good" category in cycle 2.

Abstract

This study aims to describe students' critical thinking skills in solving linear programming problems in grade XII in terms of their mathematical ability level. This study uses a qualitative descriptive approach with three grade XII students selected through purposive sampling technique as subjects, each representing high, medium, and low levels of mathematical ability. The research data were obtained through a linear programming problem-solving test instrument and in-depth interviews which were analyzed through data condensation, data presentation, and conclusion drawing. The results obtained indicate that high-ability students use all critical thinking indicators. They are able to formulate problems, model mathematics, check and solve problems, draw detailed conclusions, write and explain the final answer in detail, and review the answers obtained. Meanwhile, students with medium ability also fulfill all indicators. They are able to formulate problems, model mathematics, check and solve problems, draw conclusions, write and explain the final answer, and review the answers. Meanwhile, low-ability students only master three critical thinking indicators: formulating problems, modeling mathematics, and checking and solving problems. Overall, the difference in students' mathematical ability levels is directly proportional to the depth of achievement of critical thinking indicators in solving linear programming problems.
