Abstract

This study describes adequate numeracy learning in schools for future mathematics teachers in North Kalimantan. It involved 30 students as respondents who observed numeracy teaching carried out by local facilitator teachers in Bunyu district, North Kalimantan. The researcher utilized the REACT contextual approach to offer practical experience in school numeracy teaching. The respondents, assuming the role of students receiving numeracy instruction, observed the teaching process, filled out questionnaires, and provided feedback on the activities through interviews. We used mode score analysis and synthesis of interview results to analyze the student response data descriptively and quantitatively. The results showed that students who attended lectures with the REACT contextual approach strategy responded positively with a response mode score of 4, which is in the excellent category. The interview results showed a clear positive response from most students after participating in the activity. The students expressed that the lecturer's new strategy helped them acquire knowledge and achieve lecture objectives. Therefore, the application of the REACT contextual approach in innovative learning model lectures on effective numeracy teaching for future mathematics teachers in North Kalimantan has proven highly effective.

Abstract

Penelitian ini merupakan penelitian tindakan kelas yang bertujuan untuk mendeskripsikan penerapan pembelajaran berdiferensiasi dalam meningkatkan hasil belajar peserta didik pada mata pelajaran matematika.. Penelitian dilakukan di SMP Negeri 3 Tarakan pada semester genap tahun pelajaran 2023/2024 dengan subjek penelitian 27 orang peserta didik kelas VII. Prosedur penelitian tindakan kelas mengikuti alur model Kemmis dan Taggart, dimulai dari perencanaan (menyusun modul ajar, perangkat pembelajaran, lembar observasi, dan instrumen evaluasi), pelaksanaan (penerapan pembelajaran berdiferensiasi), evaluasi (tes di setiap akhir siklus pembelajaran), dan refleksi (identifikasi kekurangan dan kelebihan di akhir siklus pembelajaran). Data dikumpulkan melalui lembar observasi dan hasil tes evaluasi di setiap akhir siklus pembelajaran, kemudian dianalisis menggunakan analisis kuantitatif deskriptif. Hasil penelitian menunjukkan bahwa dari 27 peserta didik, ketuntasan klasikal pada siklus I mencapai 70,37%, dengan 19 peserta didik memenuhi standar ketuntasan dan 8 peserta didik belum memenuhi standar ketuntasan. Pada siklus II, ketuntasan meningkat menjadi 88,89%, dengan 24 peserta didik memenuhi standar ketuntasan dan hanya 3 peserta didik yang belum mencapai ketuntasan minimal. Penerapan pembelajaran berdiferensiasi dalam mata pelajaran matematika dapat meningkatkan hasil belajar peserta didik melalui pengelompokan berdasarkan kemampuan peserta didik, pengembangan materi yang bervariasi sesuai kemampuan peserta didik, dan pendekatan individu.

Abstract

The purpose of this study is 1) to analyse the response patterns of class XI high school students to the final Assessment, 2) to estimate the parameters of mathematics questions for the Class XI Final Assessment, and 3) to describe the consistency of class XI students' answers in the final Assessment. This research is the ex post facto type of research. Data collection techniques are carried out using documentation of high school students' responses in answering mathematics questions in the final odd semester assessment of 194 students. Student responses were analysed using the 2-PL (Logistic Parameter) model with the help of the R program. The item difficulty level was between -10.266 to 1.445, and the item differentiation index was -0.946 to 2.476. Most of the students' ability estimates were in the medium category with an interval of 1≤θ≤ 1. Based on the item parameters and students' abilities, it was found that 132 students were consistent in answering questions, and 62 students were inconsistent in answering questions, meaning that 62 students answered questions not based on their abilities. The results showed that the majority of students consistently answered the questions. This means that the scores obtained by students are in accordance with the students' abilities.

Abstract

This study aimed to determine the improvement of science learning outcomes by applying the RODE learning model. The subjects in this study were 19 students in the eighth grade of SMPN 3 Karang Intan in the even semester of the 2022/2023 academic year. Three observers assessed the RODE model implemented by the science teacher in her class on hydrostatics pressure material in the first cycle and Archimedes' law material in the second cycle. The Four pretest-posttest questions calculated the students' science learning outcomes. The success criterion of this study was that ≥ 75% of the research subjects obtained a score of ≥70. The data analysis used mode scores on observation data and pretest-posttest results for each cycle. According to the data analysis results, Teachers can apply the RODE learning model very well, with the mode score increasing from 3 in the first cycle to 4 in the second. 100% of students' science learning outcomes increased, with a mode score of 5 becoming 70 in the first cycle and a mode score of 30 becoming 100 in the second. Thus, the RODE learning model enhanced the science learning outcomes of eighth-grade students of SMPN 3 Karang Intan.
