Development Mathematics Learning Achievement and Mathematical Problem Solving Ability on Equation of the Level 1 Vocational Certificate Students using Cooperative Learning Technique LT

Abstract

The purposes of this research are to investigate the effect of problem-based learning on (1) To development of mathematics subject learning plan for vocational certificate level 1 student. By LT practice and conventional approach on subject of equations. Following the standard efficiency 75/75 (2) To study the learning efficiency achievement of vocational certificate level 1 student. (3) To compare the learning achievement of equations subject. (4) To compare performance of hoe to solution the mathematics problems by LT practice and conventional approach. The data were collected from 50 student of vocational certificate level 1 of Nakhonpanom University By group random ness (Cluster Random Sampling) to divided into group control.

The results were as Follows 1) The efficiency of learning by LT Practice and normal learning Practice 84.74/82.40 and 79.24/76.93, respectively, which is higher than the specified 75/75 threshold. 2) With regard to the pupil’s learning by achievement in mathematics analytical skill, it was 66% and 61% by standard. 3) The mean score of the pupil’s achievement and skill of mathematics problem solving and control group ware statistically significant differences as at the .05 of significant. 4) Year 1 vocational certificate student at study by learning management Cooperative techniques LT has the ability to. Solving mathematical problem on equation higher than student. Study by normal learning management. Statistically significant. At the level .0500กผดเผเเดเ้เห้่เด่ ิ-เดก
