ABSTRACT
This study entitled "Effect of Content and Task Based approaches on vocabulary development at JSS2 level of Zaria Local Government" was conducted to find out the effect of Content Based Language Teaching (CBLT) and Task Based Language Teaching (TBLT) approaches on vocabulary development of JSS2 students. Four specific objectives, research questions and hypotheses were formulated. Mixed method comprising quasi experimental pre-test and post-test design and questionnaire was adopted for the study. The population for the study was the 2 secondary schools in Zaria Local Government (Government Junior Secondary School Tudun Wada, and Government Secondary School, Kofa Jatu). A sample of 120 males and female students of were selected from both schools using the stratified random sampling method. The students were given a pre-test before they were taught using CBLT and TBLT approaches after which a post-test was administered. The data collected were analyzed using inferential statistics and was used to answer research questions while paired t-test statistics was used to test the hypotheses. Research question one showed that CBLT was effective for vocabulary development students, research question two showed that TBLT also had effect on students' vocabulary development. Research question three proved that CBLT was more effective for vocabulary development than TBLT, while research question four showed huge difference in the vocabulary development of students exposed to CBLT and TBLT (experimental group) than those in the controlled group. The study concluded that students taught using CBLT and TBLT can better learn new words and apply same in appropriate contexts. The researcher recommended, among others, that English language teachers should take advantage of the CBLT and TBLT approaches for vocabulary development of students at the JSS level of education.
