This study aims to find out the significant differences between students' mathematical understanding abilities that are taught using the Cooperative Learning Model type Auditory Intellectualy Receptition (AIR), Numbered Heads Together (NHT), and conventional learning models, and which learning model gives better results to improve students' mathematical understanding abilities. This type of research is quasi-experimental. The population in this study was class VIII 27 of Seluma State Junior High School consisting of 4 classes. The sample of this study was chosen 3 classes randomly, namely class VIII A as the experimental class I using the Cooperative learning model type Auditory Intellectualy Receptition (AIR), class VIII B as the experimental class II using the cooperative learning model type Numbered Heads Together (NHT), and Class VIII C as a control class using conventional learning models. Data collection on student mathematics learning outcomes in the form of tests consisting of pre-test and post-test. Data were analyzed using ANAVA and BNT. Based on ANAVA results, there are differences between students' mathematics learning outcomes in experimental class I, experimental class II, and control class. Based on the LSD test it was found that the treatment between the experimental class I with the experimental class II, the experimental class I with the control class, and the experimental class II with the control class there were differences. Auditory IntellectualyReceptition (AIR) cooperative learning model provides better results than the Numbered Heads Together (NHT) type of cooperative learning model and Conventional learning model.Keywords: mathematical understanding ability, AIR, NHT, learning model
Stunting menjadi masalah dunia karena implikasinya menentukan masa depan bangsa. Indonesia sebagai negara berkembang memiliki tingat prevalensi stunting tinggi. Menurut data Riset Kesehatan Dasar (Riskesdas) tahun 2018 angka prevalensi stunting tercatat 8,7 juta (30,7%) bayi berumur bawah lima tahun (balita) stunting. Angka ini masih jauh dari angka target yang ditetapkan oleh Badan Kesehatan Dunia (WHO), seharusnya angka stunting tidak lebih dari 20%. Kendala pelaksanaan pencapaian target penurunan stunting antara lain belum tersedianya strategi komprehensif untuk dijabarkan dalam pelaksanaan program intervensi mendukung pencegahan stunting, mulai perbaikan gizi dan kesehatan ibu dan anak balita pada 1.000 Hari Pertama Kehidupan (1.000 HPK). Metoda ini menggunakan pendekatan kualitatif deskriptif dengan teknik Ceramah Penyuluhan, Analytical Hierarchy Process (AHP) dan SWOT penentuan alternatif program intervensi dan strategi yang efektif untuk percepatan penurunan stunting. Hasil menunjukkan program intervensi sasaran utama peningkatan pola asuh anak balita/bawah dua tahun (baduta) melalui program intervensi peningkatan status gizi.
This study aims to determine the significant differences in students' mathematical problem-solving abilities using the Pictorial Riddle-based Inquiry learning model and conventional learning models. This type of research is quasi-experimental research. The population in this study were students of class XI IPS SMAN 4 Bengkulu City. The sample in the study was taken 2 classes randomly, namely class XI IPS 3 as the experimental class 1 and class XI IPS 5 as the control class. The mathematical problem-solving ability test obtained that there is a significant difference between the mathematical problem-solving abilities taught using the Pictorial Riddle-based Inquiry learning model and the conventional learning model. The inquiry learning model based on Pictorial Riddle provides an average result of mathematical problem-solving ability that is better than conventional learning models.
This study aims to determine whether the Snowball Throwing learning model can improve students' cognitive learning outcomes in quadrilateral and triangle material class VII A of Middle School 3 Kepahiang. The type of research used in this study is class action research the model of Kurt Lewin through four stages, namely: planning, action, observation and reflection. The research subjects were all students of class VII A of SMP 3 Kepahiang consisting of 26 students. This research was conducted from january 23 to February 13, 2019. Data collection techniques in this study were observations and tests, with research instruments observation sheets and test sheets. Data analysis techniques in this study used descriptive statistics, namely by percentage. Based on the observation sheet, the teacher's activity in the third cycle of teacher activity is classified as a good criterion and, every aspect has been in sufficient complexity. Based on the results of the evaluation test in Cycle III classical completeness was . Based on the results of the third cycle that has met the indicators of success, the research was stopped. Thus it can be concluded that the application of the Snowball Throwing learning model is well implemented and can improve students' cognitive learning outcomes in quadrilateral and triangular material in class VII AKepahiang 3 Public Middle School.Keywords: Snowball Throwing, Cognitive Learning Outcomes
