Abstract

The application of 2013 curriculum which has not been implemented perfectly become a problem in the learning process. This research aimed at knowing the effect of implementing Project Based Learning model with Google Classroom media toward student learning achievement on Chemistry subject, especially Reaction Rate lesson. It was an quasi experiment research with posttest only control group design. The eleventh-grade students of MIA were the population of this research. Random sampling was used in this research, and it was obtained the eleventh-grade students of MIA 1 (experimental group) and MIA 2 (control group). Interview, test, observation, and documentation were the techniques of collecting the data. Analyzing the data was using Independent t-test. Based on the results of Independent t-test with α=0.05, it was obtained the cognitive score of sig. (2 tailed) 0.046 (H0 was rejected). It showed that Project Based Learning model with Google Classroom media facilitated better learning achievement than the model without the use of Google Classroom media.

Abstract

This research aimed at increasing student learning achievement on Ion and pH Saline Solution Equilibrium lesson by using Schoology blanded Learninglearning model. Qualitative method was used in this research with quasi- experimental research design. All the eleventh-grade students of Natural Science of State Senior High School 1 TapungHilir in the Academic Year of 2018/2019 were the population of this research, and the samples were the eleventh-grade students of Natural Science 1 as the experimental group and the students of Natural Science 2 as the control group. Pretest-posttest control group design was used in this research. Sampling was done by using random technique. Analyzing the data was using one-way ANOVA. The data were analyzed by using inferential statistic with the help of SPSS 16.0 software. The results of calculating the data showed that the score of Sig. was lower than α, the significance score was 0.003. It showed that the learning achievement mean on Ion and pH Saline Solution Equilibrium lesson was increasing through the use of Schoology based Blended Learning. It could be concluded that there was an effect of using Schoology- based Blended Learning toward student learning achievement on Ion and pH Saline Solution Equilibrium lesson.

Abstract

Abstrak Penelitian ini bertujuan untuk mengembangkan instrumen Scientific Habbits of Mind (SHOM) dan melakukan analisis validitas isi instrumen SHOM dalam pembelajaran kimia menggunakan indeks validitas Aiken. Metode penelitian ini adalah Research & Development dengan model ADDIE. Data validitas isi diperoleh dari empat validator ahli. Validasi isi dilakukan menggunakan lima kriteria penilaian: tidak valid, kurang valid, cukup valid, valid, dan sangat valid. Scientific Habits of Mind terdiri dari tujuh indikator: mistrust of arguments from authority, open-mindedness, scepticism, rationality, objectivity, suspension of belief dan curiosity. Dari hasil analisis validitas isi instrumen SHOM menggunakan indeks Aiken, dapat disimpulkan bahwa sebagian besar butir instrumen SHOM memiliki validitas isi yang tinggi, sebanyak 16 dari 21 butir instrumen SHOM memiliki nilai indeks Aiken di atas 0.8, yang menunjukkan validitas yang tinggi dan 4 butir instrumen menunjukkan validitas sedang. Indeks Aiken untuk keseluruhan instrumen adalah 0,83 dengan kategori tinggi.
