Pengaruh Strategi Pembelajaran Kooperatif Tipe Stad Terhadap Kemampuan Berpikir Kreatif dan Pemecahan Masalah Matematis Siswa

Azizah Yusra Amaliyah Harahap — 2021-11-06

This study aims to determine the effect of STAD type cooperative learning strategy on students' creative thinking and mathematical problem solving abilities. This research is a quantitative research with a quasi-experimental type of research. Data analysis was performed by analysis of variance (ANOVA). The population of this research is junior high school students and the sample of this research is Class VIII. The results showed that: 1) creative thinking skills and mathematical problem solving abilities of students who were taught using STAD type cooperative learning strategies were different from those of ordinary learning; 2) there is a significant effect between creative thinking skills and students' mathematical problem solving abilities using STAD type cooperative learning strategies compared to ordinary learning; 3) there is a significant interaction between the learning model used on students' creative thinking skills and mathematical problem solving abilities.

Kesulitan Siswa SMA Dalam Menyelesaikan Soal Cerita Matematika Materi Peluang

Nova Yanti Sinaga — 2021-11-06

Mathematics story problems are math problems that are arranged in relation to the reality that exists in the student's environment which are useful for training students to see the relationship of mathematics to their lives and increasing their understanding of a mathematical concept. Regarding this, in learning mathematics there are still many students who have difficulty in solving story problems. This study aims to describe the difficulties of class XI IPA 2 students at SMA Negeri 8 Medan in solving story problems on the subject of opportunity. This type of research is descriptive qualitative research. Data collection techniques in this study were tests and interviews. The difficulties experienced by students are analyzed based on the objects of study or basic mathematical objects (facts, concepts, operations, and principles). From the results of data analysis, the difficulties experienced by students in solving the story of opportunity problems, namely: 1) Difficulty in facts, students were wrong in making a settlement plan possible because of errors in interpreting the meaning of the question, 2) Concept difficulties, students could not distinguish the use of formulas. combinations and permutations, 3) procedural difficulties, students still have difficulty in working on factorial number arithmetic operations, 4) principle difficulties, students still have difficulties in using existing principles such as "crossing out rules" in the form of factorial number division. The factors that cause students' difficulties in solving story problems of opportunity, among others, are due to mastery of concepts that are not yet good, lack of practice in working on problems, and lack of student interest in learning mathematics

Pengembangan Lembar Kerja Berbasis Budaya Lokal dan Instrumen Tes Kemampuan Berpikir Statistik Siswa SMA Sesuai dengan Kurikulum 2013 di Indonesia

Rahmi Ramadhani — 2021-11-06

This study aims to develop student worksheets based on local culture and statistical thinking skills instruments for high school students in accordance with the provisions of the 2013 Curriculum in Indonesia. The subjects in this study were students of the second year of high school. This research is a development research using the 4D type developed by Thiagarajan, Semmel and Semmel. Research on the development of the 4D type consists of four stages, namely define, design, develop and disseminate. The worksheets and test instruments have been validated with minor revisions and the results of the readability test show that the reliability score on the test instrument is 0.831. The results obtained indicate that the LKS based on local culture and statistical thinking ability test instruments are valid, practical and effective for use in learning mathematics in senior high schools

Analisis Kemampuan Pemahaman Konsep Siswa Pada Topik Barisan dan Deret Aritmatika yang Dibelajarkan dengan Model Pembelajaran Discovery Learning

Rustam E Simamora — 2021-11-06

This research is a simple study that aims to analyze the ability to understand mathematical concepts that are learned with the discovery learning model on the subject of mathematical sequences and series. The conclusion shows that the students of class XI IPA 3 SMA Negeri 1 Pagaran showed a positive response to the discovery learning learning model. This learning model is still new to students, and students are not familiar with the student centered learning model. The ability to understand concepts in this study was not achieved optimally because students were already patterned with traditional learning. In addition, the learning tools used have not been developed properly even though students need scaffolding in concept discovery and solving mathematical problems posed in learning. This simple research reveals the need for well-developed learning tools before implementing them in real learning in the classroom

Penerapan Pembelajaran Online terhadap Hasil Belajar Siswa pada Mata Pelajaran Matematika

Muhammad Rizky Mazaly — 2021-11-06

This research aims to find out how the application of online learning, how the level of readiness of teachers in organizing online learning, how the level of readiness of students in online learning and how learning outcomes are especially in mathematics subjects. This type of research is included in qualitative research. Data sources in this study include the results of class X teacher interviews. This data collection is done by conducting interviews, observations, and documentation. The results of this study show that the first learning is the process of teaching and learning carried out in and with the help of the internet network. Second, the level of readiness of teachers in the implementation of online learning at Budi Agung Medan Private Elementary School is not quite ready. Teachers are still experiencing obstacles in the use of appropriate media for online learning. Third, the level of readiness of students in online learning is quite ready, with students who have prepared facilities that support online learning such as mobile phones. Fourth, student learning outcomes during online learning are for math subjects’ students obtain low learning outcomes with 16.7% meeting the Minimum Completion Criteria, while for the entire subject, learning outcomes obtained more than 80% have achieved the Minimum Completion Criteria
