Applying Student-Problem Chart, Grey Student-Problem Chart and Grey Structure Modeling to Analyze the Effect of an Elementary School English Remedial Instruction

Student-Problem (S-P) chart, Grey Student-Problem (GSP) chart and Grey Structural Modeling (GSM) are graphical analysis tools to represent the relationship between students and test items which can be applied to diagnose, analyze, and evaluate students’ learning situation and achievement. This study has adopted a combination of these graphic analyses to assess the effect of an elementary school remedial instruction. A group of 20 fourth graders in Taipei city participated in this study, and an English test, consisting of four sections with 25 question items in total, which is based on the textbook in the fourth grade, was conducted before and after the remedial instruction. The results indicated that S-P chart, the distribution diagram of student and item types, GSP and GSM graphs effectively diagnosed students’ learning condition and items’ difficulty, and demonstrated the effect of students’ achievement and the change of test items’ types. It is strongly recommended that teachers utilize these methods in assessing the progress of their teaching and their students’ learning.
