Abstract

Paradigm of education requires a better change in students’ behavior. To challenge these problems, the improvement way of learning is needed. Inquiry method is associated to improve student learning outcomes and activities. The purpose of this study was to determine the differences of student learning outcomes and activities that is learned between the inquiry method and conventional learning. The population of this study was all students from five classes in grade VII MTsN Bakti Pidie City academic year of 2010/2011. The samples were randomly selected (random sampling) with VII2 grade students as the experimental group and VII4 grade students as a control group. The data was collected through paper and pencil test: pretest and posttest and non-test through observation sheet. The data is analyzed using t-test, moreover student activities were analyzed by percentage formula. The analysis of data shows t count= 3.80 and ttable = 2.64, it is indicated that the student learning outcomes by methods of inquiry is significantly different from student learning outcomes with conventional methods. Students teaching by Inquiry learning are more active than students teaching by conventional learning.

Abstract

Telah dilakukan penelitian pembuatan membran komposit khitosan-PVP (polivinil pirolidon) berikatan silang dengan variasi komposisi. Khitosan yang digunakan adalah hasil deasetilasi khitin dari kulit udang. Pembuatan membran komposit khitosan berikatan silang dilakukan dengan variasi komposisi PVP:khitosan dan variasi konsentrasi asam sulfat yang digunakan sebagai pembentuk ikatan silang. Hasil penelitian menunjukkan komposisi PVP:khitosan optimum adalah 0,1:2 (b/b) dengan persen penyerapan sebesar 88,62% dan konsentrasi optimum H2SO4 adalah 0,5 N. Waktu kontak dan pH optimum diperoleh pada 15 menit dan pH 4. Kinetika adsorpsi dipelajari berdasarkan persen adsorpsi pada pH yang berbeda dan mekanisme adsorpsi yang terjadi. Hasil penelitian menunjukkan bahwa konsentrasi H+ dan gugus amino yang ada pada khitosan mempengaruhi laju adsorpsi, dimana semakin besar konsentrasi H+ dan gugus amino semakin besar laju adsorpsi, sehingga kinetika adsorpsi fenol merupakan orde 2. Isoterm adsorpsi fenol pada membran komposit khitosan berikatan silang mengikuti isoterm adsorpsi Langmuir dengan nilai kapasitas adsorpsi maksimum sebesar 0,071 mg/g.Kata kunci: khitosan, membran, polivinil pirolidon

Abstract

The general puposes of experiencing math subject to elementary and middle school students are; first preparing the students to face the changing of real life through the thinking rehearsal based on the effective, effisien, honesty, critical, rationale, and logical way of thinking, and second, preparing the students to apply the mental principle of math in their daily life and as basic in learning other disciplines. Regarding to the importance of learning this subject, teacher of math should be able to create an effective teaching learning process to stimulate and to rise students enthusiasm in learning match. One of the strategy that can increase students desire in learning math is PAILKEM (Pembelajaran Aktif, Inovatif, Lingkungan, Kreatif, Efektif, dan Menarik). There is an interactive dialoque between teacher students and students-students, during teaching-learning process.This creates a condusive situation in wich students feel free to discuss their problems in learning math to their teachers and their classmates. At the end, through this strategy, students can increase their ability in learning and it is hoped that teaching learning process will be done in optimal achievement.

Abstract

The  purpose  of  this  research  is  to  know  whether  students’  understanding  of mathematics  concept  by  using  Inside-Outside  Circle  method  is  better  than  students’ understanding  of  mathematics  concept  by  using conventional  method  for  student  garade VIII of SMPN 11 Padang. The kind of this research is experimentalresearch, by using students in class VIII D and VIII E as samples which registered in 2011-2012  academic year. The instrument of this research is written test in essay form based on  the indicator of concept understanding.  Based on the data analysis to test the hypothesis, it is found that P-value 0.013  is lower than  α=0.05, it means that Hois rejected and H1is accepted. So, it can be  concluded  that  students’  understanding  of  mathematics  concept  by  using  InsideOutside Circle method is better than students’ understanding of mathematics concept  by using conventional method.Key Word: Lingkaran Dalam Lingkaran Luar, Pemahaman Konsep Matematis

Abstract

Education is proposed to cause humans to have good personality and characters. The implementation of character education needs whole understanding about the concept of character building and education. Building the students’ character is not an easy and simple task, but it needs some serious efforts which should be continuously done. Therefore, government has promoted curriculum based-character from 2010-2014, by which the character education is not only assigned to one of the subjects as Citizenship Education, but also to other subjects including mathematics. Mathematics is one of the subjects supporting the government program of character education, because some character values, as honesty, responsibility, care network, independence, and etc have been integrated in it. Thus, learning mathematics is not only focused on gaining cognitive purposes, but also on gaining affective and psychomotor purposes. In learning process, the teacher character so that the students can put him or her as the rule model. Key Word: Character Education

Abstract

The infortance of mathematics’ role indicates that the students have to learn mathematics seriously, and actively. So, they are able to understand the concept of math, reasoning and communication, and problem solving. The reasearcher found that students of class XI Social department SMAN 12 padang dit not understand concept of math well. It could be seen from the degree of completeness of mid semester 2008-2009 academic year, taht was only 53%.One of learning model that was applied to overcome this problem was cooperative learning type Group Investigation (GI). Investigation is a learning activity which gives a chance to students to improve their understanding through several activities and the result will be suitable with the students’ development. The research Questions of this study were: 1) How were the activities of the student class XI Social department SMAN 12 Padang through Group Investigation (GI) approach?, 2) How were the result of learning of students class XI Social department SMAN 12 Padang applying Group Investigation?This study was pra experiment, it was One-short case study design, in which this research was done only on one group without having control group.Based on data analysis, it could be concluded that generally students’ activity tend to icrease. Based on post-test, it was gotten that the mean score of the result of math learning was 68.18 in which the percentage of completeness was 82.05%

Abstract

This research based on the lack of comprehension of the mathematical concepts that students look at learning outcomes math class VII student SMPN5 Padang and less active in group discussions. This study aimed to determine whether students comprehension of mathematical concepts with the application of cooperative learning type think pair share a better comprehension of the mathematical concepts that students applying conventional teaching class VII SMPN 5 Padang academic year 2012/2013, and to determine whether the application of Cooperative Learning type Think Pair Share cooperative Mathematics Learning effective. This type of research is experimental research on the subject with a random design. The research instrument is shaped final essay test with a reliability test is r11 = 0.84, and a questionnaire study of learning effectiveness. Based on questionnaire data obtained percentage of the overall indicator of the effectiveness of learning by 85,26% including the highly effective criteria. Hypothesis testing using t-test of the parties with the help of MINITAB, obtained p-value = 0.011 is less than α of 0.05, then reject H0. So, it can be concluded that the students comprehension of mathematical concepts with the application of cooperative learning type Think Pair Share (TPS) is better than the students understanding of mathematical concepts by applying conventional learning class and implementation of cooperative learning model Think Pair Share  (TPS) is very effective in learning mathematics.
