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 article reported the findings of an experiment having a goal to enchance students’ mathematical creative thinking ability (MCTA) and disposition (MD) by using exploration approach (EA). Subjects of this  research were 60 seventh grade students which selected puposively  from 5 classes in a Yunior High School in Garut. The instruments of this research were test of an essay MCTA test, and a MD scale, The research found that the grades of MCTA of students getting treatment with EA were higher than the grades of students taught by scienctific approach (SA), however there was no different grades on student’s MD.  Beside that, stdudents in both classess still realized some difficulties on solving MCTA tasks, and there was moderate association between student’s MCTA and student’s MDKeyword: mathematical creative thinking ability, mathematical disposition, exploration approach

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)

Abstract

This study is a pretest-posttest experiment control group design having a goal to analyze the role of in problem-solving approach (PSA) on students' mathematical communication ability (MCA) and self-efficacy in mathematics (MSE). The study involves 66 eighth grade students, and MCA test, and an MSE scale. The study revealed that PSA took a better role than SA in obtaining MCA and MSE. Students getting treatment with PSA obtained MCA and MSE were at good grade quality, while students taught by SA attained MCA and MSE were at pretty good grade level. Besides that, the study found there was a very high association between MCA and MSE. Like that, students expressed a positive opinion on PSA, even if, students still realized a few difficulties in solving MCA. Keywords: mathematical communication, self-efficacy, problem-solving approach
