Abstract

Abstract: The purpose of this study was to determine whether or not there was an effect of the STAD Type Cooperative Learning Model on Learning Outcomes of Primary Mathematics Circles for Class VIII Even Semester SMP Negeri 1 Padangan. The population of this study were all students of SMP Negeri 1 Padangan class VIII. The samples taken were three classes. The data collection technique used is the method used for data collection in this study by using the documentation method, and the test method in the form of multiple choice questions as many as 20 questions. The test instruments used were content validity, item validity, discriminatory power, level of difficulty, and reliability. The prerequisite test used is the normality test using the Lilliefors method and the homogeneity test using the F test. The data analysis technique used is the t test. The results of the calculation in the data analysis show that x = 81.6129 and x = 69.0625, s_1^2 = 132.286 and s_2^2 = 186.189, Fcount = 1.5102 > Ftable = 1.825 (Ho is accepted and the variance is homogeneous), it is obtained tcount = 4.0357 > ttable = 1.999 so Ho is rejected and H1 is accepted. even the 2017/2018 school year.Keywords: STAD; Math Learning Results

Abstract

Abstract: The purpose of this study was to determine the effect of the PBL (Problem Based Learning) model on the ability of Mathematical Literacy on the subject of Statistics for class XI TKR SMKN 3 Bojonegoro students. This type of research is a quasi-experimental research, because it is impossible in the study to control the relevant variables. This study used a posttest only control design. The population of all students of class XI TKR SMK Negeri 3. Cluster random sampling technique for sampling. The cluster random sampling technique is done by lottery. After the lottery, the results showed that class XI TKR 2 as the experimental class had 30 students and class XI TKR 1 as the control class had 30 students. Data collection techniques using interviews, tests and documentation. Before the questions are used, they are tested for validity, reliability, distinguishability, and level of difficulty. The data analysis technique used -t test. The results of the research. The t_count value obtained in the calculation using the Polled Variance formula is t_count = 2.0533, the significance level = 0.05 and the t_table price = 2.0017, so that the t_count> t_table value is obtained. Thus, it can be concluded that using the PBL (Problem Based Learning) model causes students to have better mathematical literacy skills than using the direct learning model on the subject of Statistics for class XI TKR SMKN 3 Bojonegoro students.

Abstract: Education is a learning process in the form of positive things, education is a basic human need both physically and spiritually so that their dignity and life are more secure in the future. Children with Special Needs (ABK) are children who have abilities below or above the average of other children. In the world of education, of course, children with special needs will have difficulty in receiving and remembering information or lessons. Children with special needs are also called extraordinary children, defined as children who are different from ordinary children in terms of mental characteristics, sensory abilities, communication, social behavior, or physical characteristics. SLB is an example of an educational institution built specifically to educate and train the abilities and skills of children with special needs. This study aims to find problems and learning difficulties experienced by children with special needs in the learning process. The research was conducted at SLB Negeri Sukamaju Abung Semuli, North Lampung using the interview method. From the results of interviews conducted with one of the teachers, it was found that the problems and learning difficulties experienced by children with special needs in SLB Negeri Sukamaju Abung Semuli, North Lampung.Keywords: Children with Special Needs (ABK); Special Schools (SLB); learning problems and difficulties

Abstract

Abstract: This qualitative descriptive study aims to determine and analyze students' mathematical reasoning abilities and self-concepts in terms of gender in seventh grade junior high school students based on triangles and quadrilaterals. The subjects of this study were students of class VII SMP, totaling 22 students. The research instrument was in the form of a test consisting of four description questions and 20 self-concept questions. The indicators of mathematical reasoning that are measured are drawing sketches, analogies, proportional reasoning, and generalizations. The results of this study showed that the mathematical reasoning abilities of female students performed better than male students. In addition, students' self-concept analysis based on questionnaire data on mathematical reasoning abilities was in the good category.Keywords: Mathematical Reasoning; Self Concept; Gender

Abstract

Abstrak: Penelitian ini bertujuan untuk mendeskripsikan pengembangan lembar kerja siswa (LKS) matematika berbasis discovery learning pada materi fungsi kuadrat yang valid, praktis dan efektif. Jenis penelitian ini adalah penelitian dan pengembangan (Research & Development). Model pengembangan dalam penelitian ini adalah model 4-D yang dikembangkan oleh Thiagarajan yang terdiri dari 4 tahapan yaitu Define (Pendefinisian), Design (Perancangan), Develop (Pengembangan), Disseminate (Penyebaran). Namun pada penelitian ini dimodifikasi hanya sampai pada tahap pengembangan (Develop). Subjek dalam penelitian ini adalah siswa kelas X IPS 1 SMAN 1 Dander tahun ajaran 2021/2022 yang berjumlah 30 anak. Teknik pengumpulan data yang digunakan dalam penelitian ini adalah lembar validasi, angket respon siswa dan tes hasil belajar siswa (pre-test dan post test). Adapun hasil dari penelitian ini menunjukkan bahwa Lembar Kerja Siswa (LKS) yang dikembangkan termasuk dalam kriteria valid dengan total skor rata-rata dari kedua validator adalah 3,15. Kemudian skor ratarata total angket respon siswa sebesar 3,35 menunjukkan bahwa Lembar Kerja Siswa (LKS) yang dikembangkan termasuk dalam kategori praktis. Sedangkan Berdasarkan tes hasil belajar siswa sebelum dan sesudah menggunakan LKS, maka nilai ?ℎ????? sebesar -5,5741 sedangkan nilai ?????? sebesar -1,6991. Berarti bahwa nilai ?ℎ????? lebih kecil dari ?????? (-5,5741 < - 1,6991). Sehingga ?0 diterima dan ?? ditolak. Setelah menggunakan LKS hasil belajar siswa meningkat. Dengan demikian dapat simpulkan bahwa LKS matematika yang dikembangkan terbukti efektif. Kata kunci: Lembar Kerja Siswa (LKS); Pengembangan; Discovery Learning Abstract: This study aims to describe the development of student worksheets (LKS) based on discovery learning mathematics on valid, practical and effective quadratic function materials. This type of research is research and development (Research & Development). The development model in this study is a 4-D model developed by Thiagarajan which consists of 4 stages, namely Define, Design, Develop, Disseminate. However, in this study, it was modified only to the development stage (Develop). The subjects in this study were students of class X IPS 1 of SMAN 1 Dander for the academic year 2021/2022, totaling 30 children. Data collection techniques used in this study were validation sheets, student response questionnaires and student learning outcomes tests (pre-test and post-test). The results of this study indicate that the Student Worksheet developed is included in the valid criteria with the total average score of the two validators is 3.15. Then the average score of the total student response questionnaire was 3.35 indicating that the Student Worksheet developed was included in the practical category. Meanwhile, based on the test of student learning outcomes before and after using the student worksheet, the value of t_count is -5.5741 while the value of t_table is -1.6991. It means that the value of t_count is smaller than t_table (-5.5741 < -1.6991). So ?0 is accepted and ?? is rejected. After using student worksheets, student learning outcomes increase. Thus, it can be concluded that the mathematical worksheets developed have proven to be effective. Keywords: Student Worksheet , Development, Discovery Learning
