Abstract

Penalaran adaptif adalah salah satu komponen kunci dari kemahiran matematika. Dalam perkembangannya diketahui penalaran adaptif didukung oleh aspek non-kognitif individu yakni affective dan behavioral. Sejumlah teori mengungkapkan peluang optimalisasi aspek non-kognitif untuk pengembangan kemampuan penalaran adaptif. Tujuan penelitian ini adalah menelusuri faktor non-kognitif yang berpeluang memberi dampak pada optimalisasi kemampuan penalaran adaptif melalui pola asosiasi yang muncul pada basis data. Pendekatan penelitian data mining dengan teknik penemuan pola asosiasi (Association Rule Mining) atau Algoritma Apriori digunakan sebagai metode penelusuran faktor. Langkah penelitian yang dilakukan yakni persiapan data (fiksasi instrumen dan penentuan sampel penelitian), pengolahan data (preprocess dan transformation), dan mining dan analisa (menentukan nilai support dan nilai confidence serta interpretasi hasil). Subjek penelitian yakni siswa Sekolah Menengah Atas di lingkungan Kota Serang yang memiliki rentang usia 16-17 tahun. Adapun untuk sampel penelitian diambil sebanyak 100 orang siswa yang mengisi tes kognitif dan non-kognitif. Berdasarkan hasil pengujian dan analisis data diketahui bahwa seorang siswa memiliki kemungkinan 100% berada di level tinggi kemampuan penalaran adaptif jika memiliki dominasi penggunaan otak kiri, self-efficacy di level yang minimal sedang, kecenderungan kepribadian Melankolis dan ­self-directed learning berada di level tinggi. Adaptive reasoning is one of the key components of mathematical proficiency. In its development, it is known that adaptive reasoning is supported by individual non-cognitive aspects, namely affective and behavioral. A number of theories reveal opportunities for optimizing non-cognitive aspects for the development of adaptive reasoning skills. The purpose of this study is to explore non-cognitive factors that have the possibility to impact on optimizing adaptive reasoning skills through association rule appeared in the database. Data mining research approach with association rule mining technique or Apriori Algorithm is used as a factor tracing method. The research steps carried out were data preparation (fixation of instruments and determination of research samples), data processing (preprocess and transformation), and mining and analysis (determining support values and confidence values and interpretation of results). The research subjects were high school students in Kota Serang who have an age range of 16-17 years. As for the research sample, 100 students were taken who filled out cognitive and non-cognitive tests. Based on the results of testing and data analysis, it is identified that a student has a 100% probability of being at a high level of adaptive reasoning skills if he has left brain dominance, self-efficacy is at a minimum level of moderate, Melancholic personality tendencies and self-directed learning are at a high level.

Abstract

This study aims to determine the feasibility of LKPD teaching materials with the probing prompting learning model to facilitate the mathematical problem solving abilities of junior high school students on the flat-sided building material (cubes and blocks) and to determine student responses to the developed student worksheets (LKPD). This study uses research and development methods with the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The results of the research data obtained, and it can be concluded that the student worksheet (LKPD) of the probing prompting model is suitable for use with the results of the material test ( x = 33), mathematics education test ( x = 54), and media expert test ( x = 63). Student responses when viewed based on the results of the overall aspect value of the limited scale test, the value ( x = 45.71) is in the very feasible category. Meanwhile, the students' responses to the wide-scale (field) test based on the overall aspect scored (x  =46.81) with a very decent category.

Abstract

This research focuses on assessing the suitability of learning media developed using Articulate Storyline 3. The foundation of local wisdom is integrated into the media to enhance algebraic thinking skills among students. The study analyzes the learning media's design, content, and effectiveness, emphasizing its potential to optimize algebraic thinking. The research employs a comprehensive evaluation, incorporating expert validation, small-scale testing, and field trials. Thirty-seven students were involved as research participants, with seven individuals for the pilot and 30 for the field scale tests. Meanwhile, five experts were employed to validate the designed instructional media. The instrument used to assess the feasibility of the instructional media was a questionnaire consisting of 32 items for student responses and 36 items for expert validators, with 17 points allocated to media experts and 19 to mathematics experts. The results demonstrate a high feasibility rating of 93,38%, indicating the efficacy of the Articulate Storyline 3-based learning media. Furthermore, students responded positively to the media, with an overall interest rating of 88,39%. The research also reveals a moderate increase in algebraic thinking skills, as reflected in the average n-gain index of 0,46 for small-scale testing and 0,39 for field-scale testing. The recommendations for future research include considerations for using free hosting to ease accessibility, enhancing interactivity in the presentation of teaching materials, and expanding the learning media to encompass diverse subjects aligned with students' needs. This study contributes valuable insights into developing and assessing technology-based learning tools, emphasizing their potential to optimize algebraic thinking skills among students.
