MODEL PEMBELAJARAN KOOPERATIF UNYUK MENINGKATKAN AKTIVITAS BELAJAR SISWA

This research aims to increase the activity of mathematic by minimize the manner of mathematic difficulty on  the  sub-material of integers and multiplication. This research has done at SMPN 2 Pejagoan Kebumen and at SMPN 8 Purworejo. In the class 7A of SMPN 2 Pejagoan Kebumen there are forty students are given “the pair checking” learning model and in the class 7A of SMPN 8 Purworejo there are thirty students given “the pair searching” learning model. There is an improvement on the implementation of “the pair searching” learning model on the sub-material of multiplication to the class 7A student of SMPN 8 Purworejo in the academic year of 2011/2012, it is marked by the first result of observation of study activity in the ask’s braveness and the give a piece of mind to the first cycle is twelve students and after the implementation of “the pair searching” learning model is twenty-two students. The result of motivation and farvor to follow of learning (to finish for the self assignment and active for doing assignment be given by teacher to the first cycle get eighteen students and the second cycle get twenty-five students. The student interaction in follow the learning activity of group for the first cycle get twelve students and the second cycle twenty-five students. The student’s relationship with the teacher during the process learning (in the team work) to the first cycle get twenty-two students and the second cycle get twnty-five students and the student participation during the learning process get twenty-five students and the second cycle get twenty-eight students. This is supported by result of satisfaction’s average 77,66 at the score distance very well, where as the first cycle get average 60,17 at the less score distance. From the result of the class measure research could be conclude that pair cheks learning model could be increase the student activity for the student seven A grade class SMPN 2 Pejagoan at the integer subject from the result get twenty-three students at the early learning become twenty-nine students at the first cycle and thirty-five students at the second cycle. The increase of the result study from 51,13 at the early learning become 61,33 the first cycle and the second cycle could be increase become 75,48 with the completeness 82,50

Enhancing Problem-Solving Skills in Mathematics: Applying LDMAT and SRL for Students with Learning Difficulties

This study examines the effectiveness of the LDMAT and SRL models in improving problem-solving skills in students with learning difficulties in mathematics. The research involved 18 junior high school students and employed a mixed research design. The assessment of problem-solving skills was conducted through pre-test and post-test measurements, consisting of 10 essay-based tests and weekly assignments. Furthermore, problem-solving understanding was assessed based on the strategies utilized by students in the post-test. Data analysis involved using paired t-tests to compare pre-test and post-test results. The findings indicate that applying the LDMAT and SRL models significantly enhanced problem-solving skills in students with learning difficulties in mathematics, particularly among female students. Moreover, the students exhibited an improved understanding of problem-solving procedures. This study underscores the efficacy of the LDMAT and SRL models in enhancing problem-solving abilities and promoting deeper comprehension of problem-solving strategies among students with learning difficulties in mathematics.Pemecahan masalah merupakan inti dari pembelajaran matematika sehingga harus diajarkan kepada semua siswa, termasuk siswa yang mengalami kesulitan belajar. Kesulitan belajar matematika merujuk pada kondisi dimana siswa mengalami kesulitan dalam memahami konsep, menghitung, atau menentukan strategi pemecahan masalah yang diberikan. Oleh karena itu, guru harus memberikan bantuan dan dukungan kepada siswa tersebut dengan pembelajaran yang tepat. Secara konseptual model LDMAT dan Self-Regulated Learner (SRL) dapat digunakan untuk membantu mengatasi kesulitan belajar. Hasil penelitian ini secara khusus menunjukkan bahwa penerapan model LDMAT dan SRL dapat membantu meningkatkan kemampuan pemecahan masalah siswa yang mengalami kesulitan belajar. Siswa secara bertahap dapat menerapkan strategi pemecahan masalah yang tepat sehingga model pembelajaran ini dapat menjadi alternatif yang baik untuk diterapkan di kelas

Efektivitas Model Pembelajaran Blended Learning Terhadap Motivasi dan Kemampuan Pemecahan Masalah pada Materi Peluang

The objectives of this study are: (1) to find out whether the motivation of students who use the Blended Learning model is better than the motivation of students who use conventional learning models and (2) To determine whether students' problem-solving abilities of those who use the Blended Learning model are better than the problem-solving abilities of students who use the conventional learning model. This research method uses quantitative research with the type of experimental research. The population in this study was all class IX SMP Negeri 33 Purworejo school year 2021/2022 totaling 214 students. The sampling technique used random cluster sampling so that class IX D was chosen as the experimental class and class IX F as the control class. The results of the hypothesis test of the difference in the mean of the two groups were obtained, and H0 was accepted. This means that the motivation and problem-solving ability in the experimental class is the same as the motivation and problem-solving ability in the control class. Therefore, it can be concluded that (1) the learning motivation of students who use the Blended Learning learning model is not better than the learning motivation of students who use the conventional learning model (2) the problem-solving ability of students who use the Blended Learning learning model is not better than the motivation and ability of students who use the Blended Learning model student problem solving using conventional learning models
