A CONSTRUCTION OF BASIC SKILLS TEST IN SCIENCE PROBLEM SOLVING FOR PRATHOMSUKSA 6 UNDER PRIMARY EDUCATION SERVICE AREA OFFICE 2

Abstract

This research aimed to 1) construct a basic skills test in science problem solving 2) verify concurrent validity and 3) construct a cutting score for determining the test score in order to improve learning management. The sample of 664 subjects were obtained by using stratified random sampling technique. Data was analyzed by using descriptive statistics. Findings were as follow : 1. The reliability of basic skills test in science problem solving was .86, the difficulty was between .35-.95 and the discrimination was between .07-.58. 2. The concurrent validity verified by using correlation between the score of basic skills test and the score of science test. The correlation coefficient was .52 which was statistically significant at α .05. 3. The cutting score was designed to be the criteria for determining the test score and considered in 3 levels; 3.1 The cutting score of the entire test score was at 50% and over. 3.2 The cutting score of each skill in the test were 80%, 75%, 70%, 65%, 60%, 55%, 50% and over for the observing skill, measurement skill, classifying skill, using numbers skill, organizing data and communicating skill, experimenting skill and constructing model skill, respectively. 3.3 The cutting score of individual score was the same as each skill score.
