Abstract

Seeing the influence of quantum teaching model on learning outcomes of cognitive learners in terms of multiple intelligences is an objective of this study. For the purpose can be achieved then the type of research used is Quasy Experiment. The technique used in sampling used is a random technique class. Data collection techniques used are tests, interviews, observations, and questionnaires. The test hypothesis used is the test of variance analysis of two streets (Anava 2 Road). However, before the hypothesis is tested, preliminary tests have been performed, namely Validity test, difficulty level, differentiation, reliability, normality and homogeneity test. Based on test results that have been analyzed found that there is the influence of cognitive learning outcomes of learners using quantum teaching model. Furthermore, there are differences in cognitive learning outcomes between learners who have logical-mathematical intelligence with learners who have interpersonal and naturalist intelligence. Further, There is no interaction between learning models and intelligence of logical-mathematical, interpersonal, and naturalist learners to cognitive learning outcomes of learners.

Abstract

This study was aimed to improve the ability of critical thinking mathematically through the application of Education Coins Of Mathematics Competition (E-COC) model in class X students. This research is Quasy Experimental Design research. The sampling technique was done by simple random class. Technique of collecting data by using test. Data analysis techniques used t-test. The prerequisite analysis test was performed by Liliefors method for normality test, Bartlett test for homogeneity test and N-Gain. Based on normality test results by using Liliefors test, homogeneity test with Bartlett and N-Gain test, it was found that the test result data from both groups were normal homogeneous and there was an increase in N-Gain. So for testing the hypothesis can be used t-test. Result of research and data analysis obtained t_hitung= 2,704 at N-Gian, while t_tabel=1,999. Therefore t_hitung>t_tabel then H rejected H1 accepted, meaning there was difference of improvement of critical thinking ability of mathematical student’s using model of Education Coins Of Mathematics Education (E-COC) and conventional learning model. Based on the research, it can be concluded the application of Education Coins Of Mathematics Education (E-COC) model can be improved the critical thinking ability of student’s.

Abstract

The ability to understand the mathematical concepts of learners is important. However, some existing research suggests that understanding of the mathematical concepts of learners is still low. The low understanding of the mathematical concepts of learners is allegedly caused because students are still difficult in solving math problems and less active in the process of learning in class. The implementation of the heuristic vee expenditure strategy is expected to improve the problem. The purpose of this study is to determine the effect of heuristic vee learning strategy on the ability to understand the mathematical concepts of learners. This research type used Quasi-Experiment Design research and sampling technique used is Probability Sampling method with Random Sampling technique. Hypothesis test used in this research is the t-test. The result of statistical test shows that the value of t_hitung based on the calculation obtained t_hitung = 2.096, and t_table = 1.998 so t_hitung>t_table, with a real level of 0.05, in other words, it can be concluded that the students' mathematical concept understanding that expected heuristic vee learning strategy better from the conceptual comprehension ability applied by the lecture method.

Abstract

The purpose of this study was to find our whether cooperative learning model Co-Op Co-Op approach POE (predict-observe-explain) can increase the ability troubleshooting mathematical students. This research is a research Quasi Eksperimental Design and design researchers used  in this study is the design of the control group pretest-postest, with a technique random class. Hypothesis test used in this research is t-test. From the results of statistical tests showed that the value of t_hitung based on the calculation obtained t_hitung = 5.500869, and t_tabel = 2.001 so that t_hitung> t_tabel. So based on these calculation can be concluded that the model cooperative learning CO-Op Co-Op approach POE (predict-observe-explain) can increase the ability troubleshooting mathematical students.

Abstract

The purpose of this study is to know whether the development of teaching materials gamification for seventh-grade students is feasible and interesting for use in junior high school. The subjects of the experiment were seventh-grade students at SMP Bandar Lampung. This research method is Research and Development (R&D), which a using Borg and Gall development model. The results of the assessment are: the expert assessment of the material giving a scored with an average percentage of 76% is categorized as highly feasible, the media or design experts scored with an average percentage of 71% categorized as feasible and the linguist gave a score with an average percentage of 69% categorized as feasible. In small group trials, an average of 3,6 was obtained with very attractive and feasible categories. In the field trial, it was found that the average of 3,4 was obtained with very attractive and feasible categories and the teacher's response to the materials gamifikasi, it was found that the average of 3,3 was obtained with very attractive and feasible categorized. So it can be concluded that the gamification teaching materials on the are categorized very attractive and feasible for use in mathematics learning in junior high school.
