Abstract

This research is introduction by the lack of the students’ understanding of mathematical concept and the mathematics learning activities by teacher center. This research is aims to determine  the implementation of active learning strategy type The Learning Cell in improving students’ understanding of mathematical concept class VIII SMPN 11 Padang. The type of research is experiment with random of subject. Population in this research is students class VIII SMPN 11 Padang who registered in academic year 2012/2013. The technique of sampling is random and selected class VIIIF as an experimental class and VIIIE as a control class. Instrument used was an essay test with a reliability test is 0,826. Based on the analysis of data obtained that the average student learning outcomes experimental class is greater than the control class. Hypothesis testing using one side of t-test with the MINITAB’S program, obtained P-value is less than α. The hypothesis is accepted at the 95% confidence level. Thus it can be concluded that the students’ understanding of mathematical concept with an active learning strategy type The Learning Cell is better than students’ understanding of mathematical concept by implementing conventional learning class VIII SMPN 11 Padang.

Abstract

The research was due to the lack of students’ ability in understanding mathematic concept. The research aimed to find out whether students’ matematic understanding which were taught using spotlight technique better that of conventional learning. The design of the research was experimental research. The population was all students of grade IX SMPN 1 Gunung Talang. Based on the result of random sampling technique, grade IX4 was chosen as the experimental group, while the grade IX7 as the control group. The instruments used were essay test and understending concept indicators. The test consisted of eight questions, the reliability was 0,7695. The data was analyzed using one way t test whit MINITAB. Based on the analysis of hypothesis, it was obtained that the p-value = 0,003 was  a. Thus, the hypotethesis was accepted. Therefore, it can be concluded that students’ math concept understanding using spotlight was better than that of conventional technique at grade IX students SMPN 1 Gunung Talang

Abstract

This research was conducted based on the phenomena indicating that the teachers did not seem to have their students study in a group and were not likely to challenge them in the form of group competition. Therefore, the students were not willing to share what they have already learned with others and this condition made their understanding on mathematical concept became unsatisfactory. This could be seen from the learning achievement of the first year students of SMPN 4 Ranah Pesisir in math in Academic Year 2012/2013. This research was aimed at revealing the use of Learning Tournament active learning strategy gave better effect on the students’ understanding on mathematical concept than that of conventional learning strategy in class VIII of SMPN 4 Ranah Pesisir in Academic Year 2013/2014. This was an experimental research which used random research design toward the subject. The population of the research was all of students in class VIII of SMPN 4 Ranah Pesisir in Academic Year 2013/2014 which was divided into two classes. By using random sampling technique, class VIII2 was chosen as the experimental class and class VIII1 was as the control class. The instrument of the research was an essay post-test whose reliability was 0.83. The result of data analysis showed that p-value < α, thus the hypothesis was accepted. In conclusion, the use of Learning Tournament active learning strategy improved the students’ understanding on mathematical concept better than that of conventional learning strategy.

Abstract

The research was due to the fact that most students were not used to have a discussion and share knowledge with the peers. Moreover, they had lack of understanding mathematical concept which could be seen from the mathematic result of grade VII students SMPN 9 Sijunjung. The research aimed at describing students activities and understanding how far the students of grade VIII SMPN 9 understood the mathematic concept using corporate identity technique with a quiz, whether it was better than conventional learning. The design was experimental research using random sampling technique. The population was students of grade VIII SMPN 9 Sijunjung. Based on the result of random sampling technique, grade VIII2 was chosen as the experimental group, while the grade VIII3 as the control group. The instrument used was observation sheet and essay mathematic test. The reliability of the test was . Based on the analysis of observation sheet, there was an improvement of students activities during the teaching and learning process and the data analysis obtained was distributed homogeny and normal. The technique analysis data used was one way t test. Based on the analysis of hypothesis using MINITAB, it was obtained that the p-value was less than . Therefore, it can be concluded the student understanding of mathematical concept using corporate identity technique with a quiz was better than conventional learning at grade VIII SMPN 9 Sijunjung.

Abstract

The background of this research by students learning motivation and comprehension of mathematical concept was low. It could be seen from students’demotivated in learning mathematic and also most of them did not do their exercises. One way to solve this problem was by implementing active learning strategy of Learning Tournament type. The purpose of this rese was by implementing active learning strategy of Learning Tournament type. The purpose of this research was answering the research question whether implementing active learning strategy of Learning Tournament type gave better improvement in students’ learning motivation and students’ comprehension of mathematical concept than by using conventional learning strategy. This strategy applied to student Grade VIII SMPN 5 Koto XI Tarusan. The type of this research was experimental research. The population in this research was the students grade VIII SMPN 5 Koto XI Tarusan year 2013/2014. The technique in choosing research sample was random sampling technique, which chose class VIII.3 as an experimental class VIII.1 as a control class. The instrument in this research was questionnaire and final tes. Questioner was used to see the differentiation of motivation score in the questioner which given in the beginning of the research and in questioner which given in the end of the research. Then, researcher also used final test by using comprehension of the concept as the indicator. The technique of data analysis was t test which was analyzed by using MINITAB. Based on the data analysis, it was known that two sample had normal disrtributions and homogenizes and hypothesis test shown P-value was last them <𝛼. So, hypothesis could be accepted. In conclusion, comprehension of mathematic concept of students Grade VIII SMPN 5 Koto XI Tarusan which was taught by using active learning strategy og Learning Tournament type got better improvement than their comprehension of mathematical concept by using conventional.
