Abstract

This paper reports findings of  a  post test experimental control group design conducted to investigate the role of modified Moore learning approach  on improving students’ mathematical understanding and proving abilities. Subject of study were 56 undergradute students of one state university in Bandung, who took advanced abstract algebra course. Instrument of study were a set test of mathematical understanding ability, a set test of mathematical proving ability, and a set of students’ opinion scale on modified Moore learning approach. Data were analyzed by using two path ANOVA. The study found that proof construction process was more difficult than mathematical understanding  task  for all students, and students still posed some difficulties on constructing mathematical proof task.  The study also found there were not differences  between students’  abilities on mathematical understanding and on proving abilities of  the both classes, and both abilities were classified as mediocre. However, in modified Moore learning approach class there were more students who got above average grades on mathematical understanding than those of conventional class. Moreover, students performed positive  opinion toward  modified Moore learning approach. They  were  active in questioning and solving problems, and in explaining their works in front of class as well, while students of conventional teaching prefered to listen to lecturer’s explanation. The study also found that there was no interaction between learning approach and students’ prior mathematics ability on mathematical understanding and proving abilities,  but  there were  quite strong  association between students’ mathematical understanding and proving abilities.Keywords:  modified Moore learning approach, mathematical understanding ability, mathematical proving ability. DOI: http://dx.doi.org/10.22342/jme.2.2.751.231-250

Abstract

The goal of this research is to examine  the role of contextual teaching-learning  approach (CTLA) toward  students’ mathematical reasoning ability (MRA) and self concept in mathematics (MSC). The research involves 66 eighth grade students, a MRA  test,  a MSC scale. Findings of this research were:  students getting CTLA reached MRA at better grade than the grade of students who get SA learning, even if those grades were at low level. However, there was no difference grades on students’ MSC in both teaching approaches, and those grades were at fairly good level. Students in both teaching approaches encountered difficulties in solving MRA tasks such as on analogical reasoning about position of two lines,  solving tangent equation on a curve problem, and writing down the formula involved in a calculation.  Beside that, there was association between MRA and MSC, and students performed active learning during CTLA lessons.Keyword: contextual teaching-learning, mathematical reasoning, mathematcal self concept.

Abstract

This study is a quasi experimental research, which aims to examine the achievement and improvement of communication skills and creative thinking and mathematical disposition of high school students through an exploratory approach. The sample consists of 2 classes amounting to 68 students of class XI one high school in West Bandung. Instruments in this study are each set of test description of the ability of mathematical communication, and a set of mathematical disposition scale. The study found that the achievement of mathematical communication ability of high school students who received learning with exploratory approach is better than those who received regular learning reviewed in whole and the students' early mathematical ability. Likewise, the improvement of mathematical communication ability of high school students who received learning with better exploration approach than those who received regular learning reviewed in whole and early mathematical ability of their students. However, there was no interaction between the exploration approach and the students' early mathematical ability that resulted in communication skills and mathematical disposition students. For the achievement of mathematical disposition ability of students whose learning using exploratory approach is better than students with ordinary learning reviewed overall and early mathematical ability, but there is no interaction of exploration approach and KAM that resulted in mathematical disposition of students. Besides, there is also a considerable relation between communication ability and mathematical disposition of students.

Abstract

This research was a pre test-post test experimental control group design having a goal to analyze  the role of Inductive-Deductive Approach (IDA) on improving  students’ mathematical creative thinking  ability (MCTA) and self efficacy  (MSE). Subjects of this research were  70  eleventh grade students from two classes selected purposively in a Senior High School in Garut. Instruments of this research were a MCTA test, and a MSE scale. The research found that the role of IDA was greater than the role of scientific approach (SA) on improving  students’ MCTA and MSE. Students getting treatment with IDA approach obtained  MCTA and MSE at good grades qualification. While students taught by SA attained MCTA and MSE at low-moderate grades level.  Apart of those findings, the research found that students getting treatment with IDA encountered a litle bit difficulty  in solving MCTA tasks. In contrast students taught by SA experienced in allmost items of MCTA tasks.  In addition, the research also found there was no assocition between MCTA and MSE and students performed good and active learning during IDA lessons.Keyword: mathematical creative thinking,  mathematical self efficacy, model eliciting activities (IDA)
