The Development of an Instructional Model based on Constructivist Theory together with The Geometer’s Sketchpad (GSP) and Facebook to Enhance Mathematical Reasoning Ability and Students’ Learning Achievement of Mathayomsuksa Two Students

Abstract

The purposes of this research were to 1) study basic data and need develop an instructional model based on Constructivist theory together with the Geometer’s Sketchpad (GSP) and facebook to enhance mathematical reasoning ability and students’ learning achievement of mathayomsuksa two students 2) develop and study the efficiency of an instructional model based on Constructivist theory together with the Geometer’s Sketchpad (GSP) and facebook to enhance mathematical reasoning ability and students’ learning achievement of mathayomsuksa two students 3) experiment an instructional model based on Constructivist theory together with the Geometer’s Sketchpad (GSP) and facebook to enhance mathematical reasoning ability and students’ learning achievement of mathayomsuksa two students and 4) evaluate and improve an instructional model based on Constructivist theory together with the Geometer’s Sketchpad (GSP) and facebook to enhance mathematical reasoning ability and students’ learning achievement of mathayomsuksa two students. The samples  was 28 mathayomsuksa 2/1 students at Tessaban Sriboonyanusson School,           Samutsakhon Province in the first semester of the academic year 2018, from Cluster Random Sampling. The research instruments consisted of a document analyze form, a questionnaire for need develop an instructional model, lesson plans, instructional model, students’ learning achievement test, mathematical reasoning ability test and a questionnaire for students’ satisfaction to an instructional model. Percentage, mean, standard deviation and dependent sample t-test were used for analyzing data and presenting results by tables and description.

The research results were as follows :

1.The developed instructional model called EPRSEP Model consisted of 5 important factors which were 1) principle 2) objective 3) content 4) instructional and 5) implementation. The instructional process included 6 steps including 1) Encouragement (E) 2) Problem (P) 3) Reflection (R) 4)Sharing (S) 5) Explanation (E) and 6) Practice (P),The efficiency of EPRSEP Model met the criterion of 81.04/82.10 that was satisfy with the required criterion of 80/80.

2.Mathematical reasoning ability of mathayomsuka two students after getting learning management based on EPRSEP Model was good quality.

3. Students’ learning achievement of mathayomsuka two students after getting learning management based on EPRSEP Model was higher than before learning management based on EPRSEP Model at the .01 level of significance.

4. Students’ satisfaction of mathayomsuka two students on EPRSEP model was most quality.
