Abstract

Berpikir merupakan kegiatan yang paling utama ketika melakukan suatu hal. Berpikir selalu melibatkan kognitif. Penggunaan kognitif secara maksimal tentu melibatkan kehadiran dari fungsi kognitif. Kehadiran fungsi kognitif seseorang dalam menyelesaikan permasalahan matematika mengakibatkan berkembangnya fungsi kognitif seseorang tersebut. Penelitian ini merupakan penelitian deskriptif yang bertujuan untuk mendeskripsikan hasil pemetaan fungsi kognitif dan kemampuan matematika siswa. Subjek penelitian ini adalah siswa SMP kelas VIII sebanyak 32 siswa (15 laki-laki dan 17 perempuan). Data dikumpulkan dengan menggunakan metode tes dan wawancara. Instrumen yang digunakan dalam penelitian ini adalah instrument tes Feuersteins?s Instrumental Enrichment (FIE) (pengorganisasian titik, pengelompokan, dan progress numeral) dan instrumen tes matematika. Hasil penelitian menunjukkan bahwa peta fungsi kognitif dan kemampuan matematika siswa dengan menggunakan FIE jenis Pengorganisasian Titik menunjukkan bahwa, sebanyak 32 subjek terbagi menjadi sebesar 18,75% termasuk dalam kemampuan matematika tinggi, sebesar 71,875% termasuk dalam kemampuan matematika sedang, dan sebesar 9,375% termasuk dalam kemampuan matematika rendah. Untuk Jenis Pengelompokan menunjukkan bahwa masingmasing sebesar 6,25% pada fungsi kognitif yang pertama dan kedua, termasuk dalam kemampuan matematika rendah. pada fungsi kognitif yang ketiga terdapat 6,25% termasuk dalam kemampuan matematika tinggi, 3,125% termasuk dalam kemampuan matematika sedang, dan 78,125% termasuk dalam kemampuan matematika rendah. Sedangkan pada jenis Numerical Progression menunjukkan bahwa pada fungsi kognitif yang pertama sebesar 18,75% termasuk dalam kemampuan matematika rendah. sedangkan pada fungsi kognitif yang kedua sebesar 59,375% termasuk dalam kemampuan matematika tinggi, sebesar 3,125% termasuk dalam kemampuan matematika sedang, dan sebesar 18,75% termasuk dalam kemampuan matematika rendah

Abstract

Science, technology, engineering, and mathematics (STEM) problem-solving is necessary to be infused into the classroom. Nevertheless, the criticism of underrepresented mathematics in STEM problem-solving assessment is an issue. In this study, we develop and investigate the psychometric evidence of an integrated STEM-based mathematical problem-solving test. The product of the test was a mathematical essay test that contains three scientific scenarios related to the environment in every middle school grade. The mathematical contents were integrated into engineering-based design using the technology. Three experts filled an assessment sheet to assess content validity, which was analyzed using a content validity index (CVI) and intraclass correlation coefficient (ICC). The result of content validity revealed that overall items were valid and reliable. The construct validity was examined using the Rasch analysis from the data of Grades 7–9 students in Indonesia (n = 286). The construct of all scenarios and prompting items indicated fit with various difficulty levels and acceptable discrimination value. Nevertheless, four prompting items were reported as misfit based on unweighted mean square value. The recommendation for improvement is emphasized in the language clarity aspect. The inter-rater reliability was also declared good. A further study is suggested to provide a computer-based test.

Abstract

Intuitionistic Fuzzy Set (IFS) is useful to construct a model with elaborate uncertainty and ambiguity involved in decision-making. In this paper, the concept relation and operation of intuitionistic fuzzy set and the application in major of senior high school determination using the normalized Euclidean distance method will be reviewed. Some theorem of relation and operation of intuitionistic fuzzy set are proved. In general, to prove the theorem the definition and some basic relation and operation laws of IFS are needed. The distance measure between IFS indicates the difference in grade between the information carried by IFS. There are science, social, and language majors in senior high school. The normalized Euclidean distance method is used to measure the distance between each student and each major. The major, which each student can choose, has been determined depending on test evaluations. The solution provided is the smallest distance between each student and each major using the normalized Euclidean distance method.

Abstract

This research aims to examine the effect of using an Android application based on Augmented Reality (AR) in practical activities on students' science process skills. The research used a pre-experimental design with a one-group pretest-posttest design involving 35 students at MAK Madani Manado. The research results show a significant increase in students' science process skills, which can be seen from the average pretest score of 52.48 and posttest of 86.69. This increase reflects the effectiveness of using AR-based applications in helping students improve their skills in observing, classifying, formulating hypotheses, designing experiments, processing data, and drawing conclusions. AR applications provide a more interactive learning experience by allowing students to visualize abstract concepts in a real way so that chemistry learning becomes more interesting and meaningful. These findings provide a positive contribution to the development of more innovative and contextual chemistry learning strategies, as well as offering solutions to overcome limited laboratory facilities in schools. The use of AR applications in chemistry learning also supports the creation of learning experiences that are relevant to learning needs in the digital era, thereby increasing student motivation and involvement in learning.
