This study aims to: (1) examine the contribution of student activity and learning facilities to mathematical learning outcomes indirectly through learning independence, (2) examine the contribution of student activity and learning facilities to learning independence, (3) test the contribution of student learning independence to results learn math. This type of research is quantitative with the research subjects being all VII grade students of the Muhammadiyah Middle School Surakarta Special Program in 2018/2019. Data collection is done by questionnaire and documentation. The data analysis technique used is path analysis which has previously been carried out in five tests of data analysis prerequisites, namely: normality test with liliefors, linearity test, multicollinearity test, heteroscedasticity test and autocorrelation test. The results of the study with a significance level of 0.05, namely: (1) there is a contribution of student activity and learning facilities to learning outcomes indirectly through learning independence by 23.9%, (2) there is a contribution of student activity and learning facilities to learning independence by 64%, (3) there is a contribution of learning independence to mathematics learning outcomes of 15.68%.
Rendahnya capaian literasi matematika di Indonesia khususnya materi aljabar yang diujikan pada PISA memuat didalam konten Change and Relationship menjadi perhatian khusus di bidang pendidikan. Tujuan penelitian ini untuk menyelami dan membedah kemampuan literasi matematik dalam menyelesaikan soal berbasis PISA pada konten Change and Relationship dilihat dari sudut gaya kognitif. Ditinjau dari gaya kognitif, menunjukkan bahwa gaya Field Independent dan Field Dependent sangat efisien untuk menganalisis kemampuan literasi matematika. Metodologi dalam penelitian ini adalah penelitian deskriptif dengan pendekatan kualitatif. Subjek penelitian ini siswa kelas 8 SMPN 4 Jatiyoso semester gasal tahun ajaran 2020/2021. Instrumen yang dipakai dalam penelitian ini ialah uji Group Embedded Figure Test (GEFT), uji kemampuan literasi matematika, dan pedoman wawancara. Hasil penelitian memperlihatkan bahwa siswa dengan gaya kognitif Field Independent/ memenuhi kemampuan literasi matematika pada aspek communication, reasoning, and argument, devising strategie for solving problems, using symbolic, formal, and techincal language, and operation, representation. Pencapaian kemampuan literasi matematika dari siswa Field Dependent yaitu kemampuan literasi matematika pada aspek communication, reasoning and argument, using symbolic, forma/,and techincal language, and operation, representation.
This study aims to develop a learning model based on the theory of realistic mathematics education and child-friendly learning for teaching mathematics in junior high school. This research is conducted using Plomp’s educational design research that consists of four development phases: 1) preliminary investigation, 2) designing, 3) realization, and 4) revision, evaluation. In addition, this study also tests the mathematics instructional model prototype being developed and validated by an expert. Based on the analysis, it can be concluded that: 1) the teacher’s learning management in the implementation of realistic and child-friendly learning model can be classified “very good”, 2) the prototype model is categorized “very good” in improving students’ activities , and 3) the students’ responses toward the developed mathematics instructional model are "positive”. Moreover, the syntaxes of realistic and child-friendly learning model for teaching mathematics in junior high school have been formulated, namely: 1) explaining learning objectives and motivating students, 2) providing contextual problems students familiar with, or horizontal mathematization, 3) processing abstraction or vertical mathematization, 4) devising strategies, 5) communicating solution in a discussion, and 6) giving inferences of mathematics subject-matter.
Students consider that mathematics learning delivered by the teacher to be very boring, teacher-centered learning and most students said that mathematics difficult to understand. For this reason, this study aims to analyze the implementation of the discovery model based on NHT in mathematics learning in terms of students’ cognitive styles. This study uses a quantitative approach with a quasi experimental research design. The population in this study were all 7th grade students of SMP Karangmalang Sragen. The sampling technique in this study was using cluster random sampling technique. Meanwhile, the data analysis technique used two-way analysis of variance. The results showed that there were differences in the achievement of mathematics learning outcomes in terms of the use of learning models and students’ cognitive styles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
