Abstract

Additive Main Effect and Multiplicative Model (AMMI Model) nowadays is used to asses in plant breeding, especially to asses the Genotype í— Environment Interaction (GEI) on multi-environment trial. The presence of genotype í— environment interaction (GEI) creates difficulties in modeling complex trait that involve sequence biological process. Coupling Structural equation modeling with AMMI was developed to analyzed genotype í— environment interaction (GEI). Structural equation modeling allows us to account for underlying sequential process in plant development by incorporating intermediate variables associated with those processes in the model. With this method we can incorporating genotypic and environmental covariate in the model and explain how those covariates influence grain yield. SEM-AMMI useful when both environments and genotype are fixed and the purpose of the multi-environment trials (MET) is to assess the combined effect genotypic and environmental covariate on yield and yield components  Keywords : AMMI Model, Structural equation modeling

Abstract

Penelitian ini bertujuan untuk mendeskripsikan pengaruh pendekatan contextual teaching and learning (CTL) dengan setting kooperatif tipe kancing gemerincing terhadap kemampuan komunikasi matematis, kepercayaan diri, dan prestasi belajar matematika siswa SMP. Penelitian ini merupakan jenis penelitian eksperimen semu dengan dua kelompok yaitu kelompok eksperimen dan kelompok kontrol. Untuk melihat pengaruh perlakuan terhadap ketiga variabel dependen secara simultan, digunakan uji statistik Multivariate Analysis of Variance (Manova), sedangkan untuk menganalisis pendekatan manakah yang lebih unggul terhadap masing-masing variabel dependen, digunakan uji statistik Independent Sample T-test. Hasil penelitian pada taraf signifikan 5% menunjukkan bahwa ada pengaruh pendekatan CTL dengan setting kooperatif tipe kancing gemerincing terhadap kemampuan komunikasi matematis, kepercayaan diri, dan prestasi belajar matematika pada siswa SMP. Berdasarkan analisis yang dilakukan, pembelajaran matematika menggunakan pendekatan CTL dengan setting kooperatif tipe kancing gemerincing lebih unggul daripada pendekatan konvensional dalam hal kemampuan komunikasi matematis, kepercayaan diri, dan prestasi belajar matematika pada siswa SMP.Kata Kunci: contextual teaching and learning, kancing gemerincing (talking chips), komunikasi matematis, percaya diri, dan prestasi belajar matematika. Effect of CTL Approach in Cooperative Setting of Talking Chips Type on Junior High School Student’s Mathematical Communication Skill, Self-Confidence, and Mathematics Learning Achievement AbstractThis study aims to describe the effect of contextual teaching and learning (CTL) approach in cooperative setting of talking chips type on junior high school student’s mathematical communication skill, self-confidence, and mathematics learning achievement.

Abstract

Penelitian eksperimen semu ini bertujuan mendeskripsikan keefektifan pembelajaran group investigation (GI) menggunakan alat peraga manipulatif dibandingkan dengan metode ceramah menggunakan alat peraga secara klasikal ditinjau dari prestasi belajar bangun ruang sisi datar dan apresiasi peserta didik terhadap matematika peserta didik kelas VIII SMP. Populasi meliputi seluruh peserta didik SMP di DIY dengan sampel peserta didik kelas VIII  B dan C SMP Muhammadiyah 4 Yogyakarta tahun pelajaran 2012/2013, yang  diambil secara acak dengan undian. Penelitian ini menggunakan pendekatan kuantitatif dengan dua perlakuan yaitu untuk kelompok eksperimen (kelas VIII B) berupa pembelajaran GI menggunakan alat peraga manipulatif dan kelompok kontrol (kelas VIII C) berupa pembelajaran dengan metode ceramah menggunakan alat peraga secara klasikal. Pretes dan postes digunakan untuk mengukur prestasi belajar bangun ruang sisi datar dan angket apresiasi untuk mengetahui tingkat apresiasi terhadap matematika. Hasil penelitian menunjukkan bahwa (1) pembelajaran GI menggunakan alat peraga manipulatif efektif baik jika ditinjau dari prestasi belajar bangun ruang sisi datar maupun apresiasi terhadap matematika; (2) pembelajaran dengan metode ceramah menggunakan alat peraga secara klasikal efektif ditinjau dari prestasi belajar, tetapi tidak efektif jika ditinjau dari apresiasi terhadap matematika; (3) pembelajaran GI menggunakan alat peraga manipulatif lebih efektif baik jika ditinjau dari prestasi belajar bangun ruang sisi datar maupun apresiasi peserta didik terhadap matematika.Kata kunci: group investigation, alat peraga manipulatif, prestasi belajar, apresiasi terhadap matematika Review of the Effectiveness of Group Investigation with Manipulatives Teaching Aid from the Aspects of Polyhedra Learning Achievement and Appreciation of Mathematics at SMP AbstractThis quasi-experiment aims to describe the effectiveness of cooperative learning of group investigation (GI) with manipulatives teaching aid compared with conventional learning method using teaching aid classically in terms of polyhedra learning achievement and students’ appreciation of mathematics of the 8th grade students. The population covered all 8th grade students at DIY with sample was all students at class VIII B and C of SMP Muhammadiyah 4 Yogyakarta in the academic year of 2012/2013, established randomly using the lottery method. This used the quantitative approach with two treatments, the experimental group (class VIII B)was  taught using cooperative learning of GI with manipulatives and for  the control group (class VIII C) using conventional learning method with teaching aid classically. Pretest dan posttest were used to measure students’ learning achievement and a questionnaireof appreciation was used to know the level of their aprreciation of mathematics. The result showed that (1) the cooperative learning of GI with manipulatives is effective both in terms of polyhedra learning achievement and appreciation of mathematics, (2) the conventional learning method using teaching aid classically is effective in terms of learning achievement, but ineffective in terms of appreciation of mathematics; (3) the cooperative learning of GI with manipulatives is more effective both in terms of polyhedra learning achievement and appreciation of mathematics.Keywords: group investigation, manipulative teaching aid, polyhedra learning achievement, appreciation of mathematics
