The effects of learning management by using open approach supplemented with skill exercises on mathematics achievement for grade 8 students

Abstract

           The purposes of this research were to 1) study the effectiveness of Learning Management By Using Open Approach Supplemented With Skill Exercises on Mathematics Achievement to the standard 75/75 criterion 2) compare the Mathematics Achievement before and after Learning Management by using Open Approach Supplemented with Skill Exercises 3) compare the Mathematics Achievement after Learning Management by using the Open Approach Supplemented with Skill Exercises with the 75 percent criterion and 4) study the satisfaction toward Learning Management By Using Open Approach Supplemented With Skill Exercises for Grade 8 Students. The Sample consisted of 20 grade 8 students in the first semester of the 2025 at Bannonngam School, by cluster random sampling. The research instruments were 1) lesson plans 2) the skill exercises form 3) the Mathematics Achievement test had difficulty values between 0.27 - 0.77, discrimination values between 0.27 - 0.67 and reliability values was 0.94 and 4) the satisfaction questionnaire. The statistics for data analysis comprised; percentage, mean, standard deviation, percentage, one sample t-test and t-test for dependent samples.

         The results of this research found that;

         1. The effectiveness of Learning Management By Using Open Approach Supplemented With Skill Exercises value E1/E2 equal 78.81/79.83

         2. the Mathematics Achievement after Learning Management By Using Open Approach Supplemented With Skill Exercises was Significant higher than before at the .05 levels.

         3. the Mathematics Achievement after Learning Management By Using Open Approach Supplemented With Skill Exercises was higher than the 75% criteria at the .05 level.

         4. the satisfaction toward Learning Management By Using Open Approach Supplemented With Skill Exercises at the highest level.
