Abstract

Students abilities can be developed through lectures, one of which is variable Calculus 2. In order for the maximum tuition required of a material that can support course lectures. In West Sumatra, Padang PGRI STKIP students only rely on one textbook only when the lectures, so the motivation and low student interest in learning. Therefore it takes a lecture materials that can help facilitate students in the lecture, which is a modul. The purpose of this study is to develop a modul valid, practical and effective in subjects STKIP PGRI Calculus 2 in West Sumatra.This study is a research development. This modul was developed by using the 4D model (define, design, develop, and desseminate). Phase desseminate not done. The data was collected with the validation and testing of the modul. modul is validated by the lecturer and expert Calculus 2, as well as Indonesian lecturers. Tests carried out on mathematics education students STKIP PGRI West Sumatra to know praktikalitas and effectiveness of the modul.         The results showed that: 1) modul is valid (including the content and construct validity) of the validators point of view, 2) the use of modul in the lecture did not experience significant barriers. The book is a practical work according to students and lecturers; and 3) modul have been effective. This is evident from the activities of students and high motivation to learn after the lecture.

Everyone Is A Teacher Here (ETH) is a learning strategy that enables students to be expected to increase students understanding of the concept of SMAN 1 Lembah Melintang are low. The purpose of this research was to find out whether the students understanding of mathematical concept by applying active learning strategy ETH type it joined handout was better than applying conventional learning. Thish research is experimental research. The research population was X grade students of SMAN 1 Lembah Melintang West Pasaman district and samples were X3 as experimental class, X6 as control class. The instrument which was used in this research was essay test with index of reliability = 0,96. Based on the result of data analysis concerning with student’s understanding of mathematical concept to both of classes. It was found that the mean score of experimental class = 76,10 and the mean score of control class = 63,53. The hypothesis testing shown that tcalculated =3.84 is low than t(0,95)(75) = 1,67, it could be concluded that the hypothesis was accepted. In other word the student’s understanding of mathematical concept by applying active learning strategy ETH type it joined handout was better than conventional learning at confidence interval 95%.

Abstract

The research motivated by the students’ less understanding about the  concept of mathematic. It seen from the results of mathematic test in the second semester of grade sevent that listed in grade VIII Putri (Pi) SMP Nurul Ikhlas in academic year 2013/2014 . One of the way to increase students’ understanding about the concept is applying Instant Assessment type of Active Learning strategy. The research purpose is to know whether students’ understanding in applying Instant Assessment type of Active Learning strategy is better than conventional learning for  grade VIII Putri (Pi) SMP Nurul Ikhlas Tanah Datar .Kind of research is experimental research and the research design is randomized to the subject . The populations are the students of eighth grade  of SMP Nurul Ikhlas that consist of 4 classes . where class VIII Pi 1 as experimental and class VIII Pi 2 as a control class . The instrumentation in the research is students’observation activity sheet and tests students understanding of mathematic’s concept . the test is in essay from with a reliability value 0,77.Based on the result of data analysis, bpth of sample class are normal and homogen in α = 0.05 and the results of hypothesis tests by using MINITAB software is P - value = 0.018 < α . It can be concluded students understanding of concepts with applying Instant Assessment type of Active Learning strategy is better than the students understanding of concepts with conventional learning .

Abstract

This research was based on the preliminary research on students of Junior High School 14 (SMPN 14) Padang who got low understanding  in mathematics concept.  This research was aimed at determining whether students’ understanding mathematics concept by applying  one of cooperative learning  called club round technique was better than applying any other convensional techniques in teaching mathematics at grade VIII of SMPN 14 Padang.This research was experimental research by having random sampling. The population were grade VIII students of SMPN 14 Padang. In order to get the sample, the researcher used random sampling and it was chosen that grade VIII. 6 students were as the experiment class and grade VIII. 5 students as the control class. The instrument used in this research was achievement test. The test form used was essay with the relialibility  =0,76. The data analysis technique used was the t-test of the party at α =0,05 with the use of Minitab Software.  Based on the analysis from those two classes, it were normally distributed and homogenous at the significance level α = 0,05 and the results obtained from testing the hypothesis P-value = 0,039, so the hypothesis was accepted. Therefore, it could be conluded that the students’ understanding of the mathematics concept by implementing cooperative learning, club round,  was better than implementing the conventional learning technique at grade VIII of SMPN 14 Padang.
