Students need an understanding of mathematical concepts provided by educators who have good skills. Educators must also maximize their teaching time so that it requires learning models such as e-learning and blended learning to meet the loss of teaching time due to other activities that must be done by the teacher besides teaching. This study aims to see the impact of blended learning and e-learning on the ability to understand mathematical concepts of students in the material of two-variable linear equations. The method used in this study is the quasi-experiment with the posttest only control design research. Technical analysis uses one way ANOVA. Based on the results of the study, Blended Learning and E-Learning influence understanding mathematical concepts in the two-variable linear equation material, so that it can be used as a knowledge given to students in understanding mathematical concepts.
This article discusses about adultery in Islamic law perspective and the book of law and criminal. By using the comparative analysis method found a difference between Islamic law and the book of law and criminal in terms define adultery as well as legal consequences. Sexual relations between young couples are not categorized as adultery in the book of law and criminal because they are not in a valid marriage bond. The book of law and criminal also does not ensnare adultery to Article 27 BW even though they are in a valid marriage bond. In addition, if the husband or wife of adultery gives permission to the partner to commit adultery, then Article 284 cannot ensnare them. While in Islamic law perspective, any sexual relations outside a valid marriage bond is categorized as adultery
This study aims to determine the effect of scramble learning models assisted by prezi on mathematical critical thinking skills. The type of research used was quasi-experimental design. Data collection was performed by tests of mathematical critical thinking skills. Data were analysed using one-way ANOVA test and continued with multiple comparisons. Hypothesis testing used one way ANOVA with a significance level of 5%. The result of hypothesis test showed F count is 3.24 and F table is 3.10 or F count is greater than F table, then, hypothesis 0 is rejected. This study found that the average score of the class using scramble learning model assisted by prezi was higher than the class that used scramble learning model and conventional learning model. Based on these results it can be concluded that there is an influence of the scramble learning model assisted by prezi on the mathematical critical thinking ability of grade VII.
Students' comprehension of the theory is often implemented as an effort to improve their achievements. However, other learning processes are rarely carried out by teachers, such as the practice or tools uses as the lesson application. The purpose of this study is to analyze the learning effectiveness by applying the geophysical surveys practice method or the use of environmental geophysics tools. The assessment of students' abilities is based on the interpretation results of environmental geophysical survey data and the presentations and discussions about the results of interpretation. The TGT Cooperative learning model was used with a quasi-experimental method and quantitative design. Data collection was carried out using a series of research instruments in the form of questionnaires. The results of the study were based on comparisons between the experimental class and the control class. The results show that the experimental class has excellent findings. 1) Based on the results of the post-test, the TGT cooperative learning method is very effective in this study, because teamwork can maintain students' enthusiasm and understanding during the learning process. 2) Retrieval of field data makes students better understand the application of geoelectric concepts and determination of rock resistivity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
