Effects of using think-talk-write technique in organizing mathematics learning activities based on inquiry model on mathematical reasoning and communication abilities
Abstract:
The purposes of this research were 1) to compare mathematical reasoning abilities between before and after using Think-Talk-Write technique in organizing mathematics learning activities based on inquiry model 2) to compare mathematical reasoning abilities between students learning by using Think-Talk-Write technique in organizing mathematics learning activities based on inquiry model and by conventional approach 3) to compare mathematical communication abilities between before and after using Think-Talk-Write technique in organizing mathematics learning activities based on inquiry model 4) to compare mathematical communication abilities between students learning by using Think-Talk-Write technique in organizing mathematics learning activities based on inquiry model and by conventional approach 5) to study development of mathematical reasoning and communication abilities of students learning by Think-Talk-Write technique in organizing mathematics learning activities based on inquiry model This research was conducted with 80 tenth grade students in academic year 2012 of Rajinibon School. They were divided into two groups, one experimental group with 40 students and one controlled group with 40 students. This instruments for this research consisted of lesson plans for mathematics learning activities using Think-Talk-Write technique based on inquiry model, conventional lesson plans, pretest and posttest for mathematical reasoning ability, pretest and posttest for mathematical communication ability. The data were analyzed by using arithmetic mean, standard deviation and t-test. The research results were revealed that: 1) Mathematics reasoning abilities of students after learning by using Think-Talk-Write technique in organizing mathematics learning activities based on inquiry model were higher than those before at the .05 level of significance. 2) Mathematics reasoning abilities of students after learning by using Think-Talk-Write technique in organizing mathematics learning activities based on inquiry model were higher than those of students learning by using conventional approach at the .05 level of significance. 3) Mathematics communication abilities of students after learning by using Think-Talk-Write technique in organizing mathematics learning activities based on inquiry model were higher than those before at the .05 level of significance. 4) Mathematics communication abilities of students after learning by using Think-Talk-Write technique in organizing mathematics learning activities based on inquiry model were higher than those of students learning by using conventional approach at the .05 level of significance. 5) After students learning by using Think-Talk-Write technique in organizing mathematics learning activities based on inquiry model, their mathematical reasoning and communication abilities were gradually developed. The students were able to analyze the relations of data, conclude, use conclusion to reasonably agree or disagree, use mathematical language to communicate, and present mathematical idea to others.
