Abstract

Penelitian ini merupakan penelitian pengembangan yang bertujuan untuk menghasilkan perangkat pembelajaran matematika berbasis Concept Attainment Model (CAM) yang valid, praktis, dan efektif terhadap hasil belajar dan aktivitas peserta didik SMP kelas VIII. Perangkat pembelajaran yang dikembangkan mengikuti prosedur pengembangan Model Plomp yang terdiri dari 3 tahap, yaitu tahap analisis pendahuluan, tahap pengembangan atau pembuatan prototipe, dan tahap penilaian. Uji validitas perangkat pembelajaran dilakukan oleh lima orang ahli dari bidang matematika, teknologi pendidikan, dan bahasa Indonesia. Pengujian kepraktisan perangkat pembelajaran diukur dari tiga hal yaitu: keterlaksanaan perangkat pembelajaran, respon peserta didik, dan respon guru. Untuk menilai efektifitas perangkat pembelajaran, dilakukan dengan mengumpulkan data melalui pengamatan terhadap aktivitas belajar matematika peserta didik selama kegiatan pembelajaran dan nilai tes hasil belajar matematika peserta didik. Hasil pegujian tersebut mengidentifikasi bahwa perangkat pembelajaran matematika berbasis CAM yang dikembangkan dinyatakan valid menurut para ahli, praktis berdasarkan guru dan peserta didik sebagai pengguna, dan efektif terlihat dari aktivitas peserta didik selama proses pembelajaran yang mengalami peningkatan. Kata kunci: penelitian pengembangan, Concept Attainment Model, hasil belajar, aktivitas belajar, Model Plomp   ABSTRACT This research is development research aims to produces mathematics learning equipment based on valid, practical, and effective CAM for learning outcome and students activity of VIII grade junior high school. The developed learning equipment uses the procedure of Plomp Model that consists of 3 stages, they are preliminary research, development or prototyping phase, and assessment phase. Validity test of learning equipment is done by 5 experts from mathematics, eduaction technology, and indonesian language. Practical learning equipment test is measured by 3 points, they are the continuity of learning equipment, response of students, and response of teachers. To assess the effectiveness of learning equipment, we use to collect data from student activity observation during learning process and mathematics test results. Those tests identifies that mathematics learning equipment through CAM-based is valid according to the experts, practical based on the teacher and student as the user, and effective based on the increasing of student activity during learning process.

Abstract

One of the most important abilities in learning mathematics for elementary students is understanding math concepts. However, elementary students’ ability to understand the math concepts in Padang is poor. The reason behind the problem is caused by inappropriate learning methods used by teachers, such as memorization. Based on this problem, the researchers conducted experimental research using guided discoverylearning methods to overcome the problem and identify its effects on the students’ ability to understand math concepts. The populations are all elementary students at grade 5in Padang who were enrolled in group V, Kuranji sub-district, semester II academic year 2017/2018. The sample selection is done by random sampling. The experimental class is grade 5 students atelementary school 44 Kalumbuk and control class is grade 5 students at elementary school 20 Kalumbuk, Padang. The data are obtained from the initial ability tests and questions in understanding math concepts. The data are analyzed using the t-test and two-way ANOVA for interaction. The results of the analysis show that: (1) guided discovery learning methods is better than conventional learning, (2) students’ math concepts understanding with high and low initial abilities taught by guided discovery learning method gets better resultcompared to conventional learning, and (3) there is no interaction between learning through guided discovery learning method and initial abilities in influencing students' ability to understand math concepts.

Abstract

Mathematics learning has so far not developed students' ability to solve problems. This can be seen from the difficulties of students in solving problems found in mathematics subjects. The purpose of this study in general is to examine the effect of PBL models and learning motivation on the mathematics learning outcomes of Class IV of SD Negeri 1 Batang Anai District, Batang Anai District, Pariaman Regency. The method used was a quasi-experimental design with 2x2 factorial design. The experimental and control groups were recruited by purposive random sampling. Data were analyzed by two-way variance t-test and analysis. The results showed that there were significant differences in learning outcomes between students taught with PBL models rather than students taught with conventional approaches, and between groups of students who were high and low motivated learning. There is no significant interaction between PBL models and learning motivation towards learning outcomes.

Abstract

This type of research is class action, with the subject of fourth grade elementary school students. The study was conducted in the even semester of the 2015/2016 academic year, the research instrument used was the effectiveness of communicating student sheets, learning outcome assessment sheets on the cognitive aspects of students at the level of knowledge and understanding. Based on the results of the study, the communication effectiveness of students in the first cycle obtained an average value of 49.99% increase in the second cycle to 67.45%, the communication effectiveness of students in the first cycle obtained an average value of 53.96% increasing in the second cycle to 71 , 42%. While student learning outcomes at the cognitive level of knowledge in the first cycle increased in the second cycle 68.33 to 80.47, cognitive learning outcomes at the level of understanding in the first cycle increased in the second cycle 58.09 to 71.42. It can be concluded that the Open Ended model can increase the effectiveness of communication and student learning outcomes in fourth grade science learning in elementary school.

Abstract

This study aims to improve problem solving skills by using problem solving methods of class VI students of Koto Alam 07 State Elementary School, Palembayan District, Agam Regency. The type of research used is Classroom Action Research. The population in this study were students of class VI of SD Negeri 07 Koto Alam, Palembayan Subdistrict, Agam Regency, who were enrolled in the first semester of the 2017/2018 school year. Class VI students number 34 people, consisting of 12 men and 22 women. This study focused on the average score of problem solving abilities of students in cycles I and II. The following data presents the results of the test: The problem solving ability of students in cycle 1 is the percentage of the classic average obtained from the test of 56%. Looking at the circumstances that occur as well as the classical average, the average percentage of students' problem solving abilities in cycle 1 is only 61%, so this is far below the indicator of success set at 75%. In cycle II the problem solving ability of students from the test with an average score of 78%.
