Abstract

The aim of this research was to describe the analyzed misconceptions in solving the sequence of the real number. This research used the descriptive research method with the qualitative explorative approach. The subjects of the research were 12 students 2013 A Program Study Of Education Mathematics, four students category of high value, four students category of medium value, and four students category of low value. The instruments used to gather data of worksheet for problem solving and interview guidelines. The data were task-based interview on the learning material of real analysis problems.They were validated by using the time triangulation and the reference fulfillment. Identification of misconceptions was conducted using Technique of Response Index (CRI) developed by Saleem Hasan with the way of tests. Analysis data this report is written with use the model miles and huberman.The result of the research are as follows: 1) the average capability understanding the concept of students on the sequence of the real number is 67,53%, 2) based on the analysis of CRI based on the criteria answer students, 16,67% (indicators 2), 16,67% (indicators 3), 8,33% (indicators 4) is students were do not know the concept (lucky guess); 25% (indicators 1), 8,33% (indicators 2), 25% (indicators 3), 16,67 (indicators 4), 16,67% (indicators 5), and 66,67% (indicators 6) is students control the concept and reasonable; and 41,67% (indicators 1), 25% (indicators 2), 33,33% (indicators 3), 41,47% (indicators 4), 50% (indicators 5), and 33,33% (indicators 6) is happened misconceptions of students.   Keywords: analyzed misconceptions, problem solving real analysis, and sequence of the real number

Abstract

Abstract: The objective of this research was to investigate the effect of learning model toward learning achievement in mathematics viewed from the spatial ability. The learning models of this research were cooperative learning model of the TAI type with AfL, the cooperative learning model of the TAI type, and the direct learning model. This research used the quasi experimental research method with the factorial design of 3 x 3. Its population was all of the students in Grade VIII of State Junior Secondary Schools of Karanganyar. The samples of the research were taken by using the stratified cluster random sampling technique. The samples consisted of 284 students. The instruments used to gather the data were test of learning achievement in Mathematics and test of spatial ability. The proposed hypotheses of the research were tested by using the two-way analysis of variance with unbalanced cells. The results of the research were as follows. 1) the students instructed TAI with AfL had a better learning achievement in Mathematics than those instructed TAI and those instructed with the direct learning model. Furthermore, the students instructed with TAI had the same learning achievement in Mathematics as those instructed with the direct learning model. 2) The learning achievement in Mathematics of the students with the high spatial ability was better than that of the students with the moderate spatial ability and that of the students with the low spatial ability. In addition, the learning achievement in Mathematics of the students with the moderate spatial ability was better than that of the students with the low spatial ability. 3) In each learning model of the TAI with AfL, TAI, and the direct learning model, the students with the high spatial ability had a better learning achievement in Mathematics than those with the moderate spatial ability and those with the low spatial ability. Moreover, the students with the moderate spatial ability had a better learning achievement in Mathematicsthan those with the low spatial ability. 4) In each of the students with the high, moderate, and low spatial abilities, TAI with AfL results in a better learning achievement in Mathematics than TAI and the direct learning model. Furthermore, TAI results in the same learning achievement in Mathematics as the direct learning model.Keywords: Team Assisted Individualization (TAI), Assessment for Learning (AfL), and spatial ability

Abstract

The aim of this research was to describe the analyzed difficulty learn student category of low value in solving the statistics problems on discussion size measure of central mainstream, size measure dispersi, and the size measure situation. This research used the descriptive research method with the qualitative explorative approach. The subjects of the research were 12 students 2013 A and 2013 B Program Study of Education Language and literature Indonesia, four students categoryof high value, four students category of medium value, andfour students category of low value. The instruments used to gather data of worksheet for problem solving and interview guidelines. The data were task-based interview on the learning material of statistics problems. They were validated by using the time triangulation and the reference fulfillment. The data were analyzed using a Miles and Huberman’s concept, that was data reduction, presentation, and conclusion. The results of the research are as follows. 1) Students categoryof low value not difficulties determining concept, using formula, and calculate solving the statistics problems on discussion size measure of central mainstream. 2) Students categoryof low valuedifficulties determining concept, using formula, and calculate solving the statistics problems on discussion size measure dispersicharacteristic coefficient of variation and permanent deviasi. 3) Students categoryof low valuedifficulties determining concept, using formula, and calculate solving the statistics problems on discussion size measure situationcharacteristic kuartilconcept from data pertain.
