Language of the TIMSS – like test and student performance in general science

Learning is the process of accumulating bits of information and isolated skills. However, language barrier could hinder efficient and effective teaching-learning process. Language is a written code for systematic science learning, and as a vehicle for constructive and creative thinking in which teachers’ primary responsibility is to transfer knowledge directly to students; and the process of learning and teaching process primarily on the interactions between the teacher and individual students.This study aimed to identify the effect of language used in the TIMSS-Like test and the science vocabulary test towards the students’ performance in General Science. Two research instruments were used in this experimental research namely; the TIMSS-Like Test and vocabulary test which was translated into Filipino and Meranao (Students Native Dialect) or chosen language. Control group was exposed to English language test while experimental group was exposed to Filipino language test and Meranao or chosen language in the test. With the use of Analysis of Variance and Correlations, results revealed that the group exposed to Filipino language test obtained highest mean gain followed by the group exposed to their own choice of language. More so, vocabulary knowledge has positive significant relationship to the students’ performance in General Science TIMSS-Like Test. Thus, it is very important for teachers’ that the language used as medium of instruction must be the language to be used in the test. Furthermore, teachers should incorporate science vocabulary in teaching scientific concepts so as to provide effective learning and understanding among learners.
