Abstract

Computational thinking is a person's ability to present problems and their solutions through certain algorithms so that the algorithms can be reused by other people and computers to solve the same problems. This study aims to comprehensively examine students' computational thinking skill reviewed from different self-efficacy levels. This research is descriptive qualitative research. The subjects in this study were 3 seventh grade students of Bumi Cendekia Junior High School in the 2022/2023 school year who were selected based on low, medium, and high self-efficacy levels. The instruments used were test, questionnaire, and interview. Data analysis was carried out using qualitative data analysis which included data reduction, data presentation, verification, and conclusion.  The results showed that students with low self-efficacy level were only able to fulfill 2 indicators of computational thinking ability, students with moderate self-efficacy level fulfilled 3 indicators of computational thinking ability. Meanwhile, students with high self-efficacy level have excellent computational thinking ability by being able to fulfill 4 indicators of computational thinking ability.

Abstract

[English]: The importance of conducting this research is due to the lack of valid and reliable assessment tools for evaluating students’ algebraic thinking ability within the context of the Indonesian school curriculum. This study aims to describe the quality of algebraic thinking test items for linear equation topics. The research procedure involves three main phases, i.e., developing the test item, conducting a sample trial, and examining the quality of the test item through Rasch model analysis. The test instrument developed in this study consists of six essay questions, each representing an indicator of algebraic thinking skill. The test instrument was then used to collect quantitative data from 37 junior high school students selected as research respondents through a purposive sampling technique. The Rasch analysis was assisted by Ministep software. The research results show that all items fall into the valid category with a reliability index of 0.81, and so the test instrument is declared to have good quality. Analysis of the item difficulty level revealed that two items fell into the difficult category, one item was difficult, one item was moderate, one item was easy, and one item was very easy. Overall, the algebraic thinking ability test instrument developed in this study has met the Rasch modelling assumption, despite the fact that some items need to be revised. The instrument can be utilized by the teacher to evaluate the students’ algebraic thinking skills in mathematics learning, specifically for linear equation topics. [Bahasa]: Minimnya instrument tes kemampuan berpikir aljabar yang valid serta reliabel dalam konteks kurikulum sekolah di Indonesia menjadikan penelitian ini penting untuk dilakukan. Penelitian ini bertujuan untuk mendeskripsikan kualitas instrumen tes berpikir aljabar pada materi persamaan garis lurus. Prosedur penelitian meliputi tiga fase utama, yaitu pengembangan butir soal, ujicoba pada sampel terbatas, dan analisis kualitas butir soal melalui analisis model Rasch. Instrumen tes yang dikembangkan berupa 6 soal essai, di mana masing-masing soal mewakili indikator kemampuan berpikir aljabar. Instrument tes selanjutnya digunakan untuk mengumpulkan data kuantitatif dari 37 siswa SMP yang dipilih sebagai responden penelitian melalui teknik purposive sampling. Analisis Rasch dilakukan dengan bantuan aplikasi Ministep. Hasil penelitian menunjukkan bahwa semua soal masuk dalam kategori valid dengan indeks reliabilitas sebesar 0.81, sehingga dapat dikatakan instrument tes memiliki kualitas yang baik. Analisis tingkat kesulitan soal mengungkapkan bahwa 2 item masuk dalam kategori sangat sulit, 1 item sulit, 1 item sedang, 1 item mudah, dan 1 item sangat mudah. Secara keseluruhan, instrumen kemampuan berpikir aljabar yang dikembangkan memenuhi kriteria pemodelan Rasch meskipun terdapat beberapa item soal yang perlu direvisi. Instrumen ini dapat dimanfaatkan oleh guru sebagai alat penilaian dalam mengevaluasi kemampuan berpikir aljabar siswa pada pembelajaran matematika, khususnya untuk materi persamaan linear

Abstract

The purpose of this study was to analyze students' proportional reasoning ability. The research subjects consisted of 21 students of VIII class in one of the public junior high schools in Semarang City who had obtained comparison materials (ratio and proportion). Data collection used test instruments that were developed based on indicators of proportional reasoning ability consisting of 6 questions. The data were analyzed qualitatively with data reduction analysis procedures, data presentation, and conclusion drawing/verification. The results showed that (1) none of the students met all the indicators of proportional reasoning ability, namely the ability to understand proportional relationships, solve proportional problems of missing values, numerical comparisons, qualitative predictions, distinguish proportional and non-proportional problems, and solve proportional relationships of inverse values, (2) all students have been able to understand proportional relationships, but they are still very limited in their ability to distinguish proportional and non-proportional problems, and solve proportional relationships of inverse value, and (3) the strategy most often used by students to solve proportional reasoning problems is the cross-multiplication strategy.
