Abstract

A good assessment instrument is an instrument that can reveal data in accordance with the actual reality, is fixed, steady or reliable, and has varying degrees of difficulty and has a good index of discrimination. Therefore this study was conducted to analyze reliability, validity, level of difficulty, and differentiation of items that can be used to reveal students' mathematics problem solving abilities. The test questions tested are questions in the form of 4 numbers. The calculation results show that the 4 test questions for problem solving ability are reliability in the medium category, and valid with each category is high. The index has difficulty number 1 in the easy category, number 2 and 3 in the medium category, and number 4 in the difficult category, and the discrimination index is quite good

Abstract

Kemandirian belajar membantu siswa fokus pada kegiatan kognitif yang diperlukan untuk memfasilitasi proses pemecahan masalah mereka. Namun tidak dapat dipungkiri adanya peningkatan pengakuan bahwa dalam banyak kasus, kemandirian belajar siswa cenderung rendah. Situasi ini membutuhkan strategi tertentu untuk membangkitkan kemandirian belajar siswa. Karena itu, dilakukan penelitian ini untuk mengetahui perbandingan pencapaian dan peningkatan kemandirian belajar matematika siswa berdasarkan intervensi model pembelajaran. Penelitian kuantitatif ini menggunakan pendekatan quasi eksperimen. Partisipan penelitian ini sebanyak 145 siswa pada dua sekolah menengah pertama di kota Kefamenanu, diantaranya 50 siswa belajar dengan model connecting, organizing, reflecting, extending dengan realistic mathematics education (CORE RME), 49 siswa belajar dengan model CORE, dan 46 siswa belajar dengan model konvensional. Hasil penelitian menunjukkan bahwa siswa yang belajar dengan model CORE RME memiliki pencapaian dan peningkatan kemandirian belajar matematika yang lebih baik dari siswa yang belajar melalui model CORE, dan model konvensional. Sedangkan perbandingan kemandirian belajar matematika antara siswa yang belajar melalui model CORE, dan model konvensional tidak terdapat perbedaan secara signifikan. Direkomendasikan agar dalam proses pembelajaran matematika di sekolah, perlu melibatkan prior knowledge siswa, real context, guided reinvention, self-development models, metacognition, self-monitoring, intertwining dan interactivity sehingga dapat mengembangkan kemandirian belajar matematika siswa.

Abstract

The School Literacy Movement (SLM) is a program designed to facilitate the acquisition of student literacy competencies. Schools that implement this government program will undoubtedly have an impact on the literacy abilities of their students, including reading literacy, scientific literacy, digital literacy, numeracy, and so on. This forms the basis for conducting research with the aim of describing the implementation of SLM in Junior High Schools throughout the Kefamenanu Sub-District. The respondents in this study include school principals, SLM administrators, library heads, Mathematics teachers, and Indonesian Language teachers. Data collection techniques employed are interviews and observation. Subsequently, data is analyzed using the flow model by Miles and Huberman, which involves data reduction, data presentation, data verification, and conclusion drawing. Findings from the research indicate that junior high schools in the Kefamenanu Sub-District have implemented SLM from the habituation stage to the development and learning stages; however, the implementation is inconsistent and not yet optimal. Thus, the execution of SLM requires maximum attention from stakeholders, involving teachers, parents, alumni, and community members.
