Abstract

This research is a merged descriptive and quasi-experiment research aimed to describe students’ creativity in developing interactive learning media with Visual Basic Application for Excel. Besides that, it had done to review students’ ability which learning used open-ended Visual Basic Application for Excel compared with the other students’ which learning used the expository method with Visual Basic Application for Excel based. The subject contained 35 students in experiment class and 33 students in the control class, where the creativity of their learning media is reviewed and is analysed using SPSS. The research result shows that: (1) Students’ creativity in creating interactive learning media that the learning used open-ended Visual Basic Application for Excel based is better than the one with expository method of Visual Basic Application for Excel found; (2) Students creativity in creating interactive learning media is the combination of their mastery towards school level mathematics and the ability in applying Visual Basic Application for Excel.

Abstract

Visual Basic Application for Excel is a simple program language and has the power to process data quickly. The utilization of math functions in Microsoft Excel can help work on Excel display more interactive so that teachers can create props inside Excel. The advantages of Microsoft Excel than other mathematical software are the many math functions and images available in the form of shapes or pictures. The availability of VBA, math and image functions in Microsoft Excel help teachers to design the creation of media related to mathematics learning, especially to develop the ability of junior high school students who have difficulty to connect mathematics lessons with basic mathematics knowledge requirements. By using VBA for Excel, the ability of junior high school students to improve in the usual way significantly with a t-test with 0.006 <0.05.  Furthermore, there is an association between the students’ self-confidence and their mathematical comprehension skills with a contingency coefficient of 0.525 including a moderate association.

Abstract

This study aims to determine the increase in mathematical dispositions of students using the open ended approach. The method used in this study is a qualitative method and this type of research is classroom action research. The population of this study was all students of class X IT Development Vocational School while the sample was class X RPL B. Data were collected based on observations, notes in the field, instruments in the form of non-disposition mathematical questionnaire scale tests. Questionnaires given contain indicators of students' mathematical dispositions, namely (1) confidence (2) can express ideas (3) check back on work results (4) persistent and diligent when working on questions (5) enthusiasm and serious learning mathematics (6) expect metacognition. The results of this study indicate that the use of an open-ended approach in mathematics learning can improve the mathematical disposition of class X RPL B students without development.

Abstract

Research on the learning ability to understand student learning independence towards mathematical punishment abilities. The research method uses correlational methods with quantitative research. The population in this study were students of one of the junior high schools in the city of Bandung and the sample of this study were students of class IX F as many as 32 students. The material used is the material of Two Variable Linear Equation System (SPLDV) which has been taught in class VIII. The instrument in this study consisted of a mathematical punishment ability test of 5 items, then a non-test instrument in the form of an independent learning scale as many as 28 positive and negative revelations. The step that needs to be done in this study is the filling of the learning independence questionnaire, a mathematical punishment ability test. The results of this study concluded that positive learning independence on the ability of students to sentence 46.6% and 53.4% ​​by other factors related to student learning independence.

Abstract

This research is a qualitative descriptive study which aims to analyze the level of students' ability to solve problems in the material of One Variable Linear Equations and Inequalities with the categorization of the level of mathematical ability of high, medium and low connections. The research subjects were class VII students as many as 39 people. The form of data collection is giving 5 items written test questions. Based on the results of the analysis, the average value of the whole instrument questions mathematical connection ability obtained 71% for indicator 1, namely using relationships between mathematical topics, 92% for indicator 2, namely using mathematics in other subjects, 85% and 80% for indicator 3 and 4 that is using mathematics in everyday life, and 58% for indicator 5, which is to understand representations equivalent to the same concept. So if totaled and averaged at 77%. Then the mathematical connection ability of class VII junior high school students is high.

Abstract

This research is motivated by the still low level of mathematical critical thinking skills of State Middle School students in Cimahi City, so a learning approach is needed to overcome these problems. Alternative approaches are applied, namely the approach to Model-Eliciting Activities. This study aims to examine the mathematical critical thinking skills of State Middle School students in Cimahi City. The method used in this study is an experimental method with research in the form of a pretest-posttest Control Group Design. The population in this study were all public junior high schools in the city of Cimahi randomly selected and selected SMP Negeri 10 Cimahi representing the characteristics of the population. The sample was chosen by two classes in a random class, namely the experimental class and the control class. Data collection in this study used a descriptive test, then the score data of the students' mathematical critical thinking skills were analyzed by descriptive and inferential statistics using the two average difference test. Based on the results of the study, both from the results of data analysis and hypothesis testing, it can be concluded that the mathematical critical thinking skills of the State Middle School students in Cimahi City whose learning using the MEAs approach are better than those using conventional learning.

Abstract

This study aims to identify and analyze aspects of the communication skills of vocational students in the material system of two-variable linear equations. The samples taken in this study were 5 students from a population of 30 students with different abilities and were taken randomly at one of the West Bandung Vocational Schools, namely class X Computer Engineering Network 2 SMK BINA INSAN BANGSA. The type of research used is qualitative descriptive. The research instrument is a test question of mathematical communication skills in the form of 4 items essays and interviews. Test results that have been carried out on several mathematical communication questions still show results below the average. It can be seen from the percentage of scores per item, namely the question no.1, obtained a percentage of 60% for indicators in explaining ideas, situations orally or in writing with real objects, graphic images, and algebra. Problem no.2 with the acquisition of 35% percentage for indicators to solve problems with the rules used. Question number 3 with the acquisition of a 25% percentage for indicators expressing daily events in mathematical language. Problem no.4 obtained a percentage of 15% for indicators connecting graphs with mathematical ideas. Then it can be concluded that the level of communication skills of vocational students is still not good enough and is classified as low because there are two problem indicators in the low category ≤ 33%
