Using Structured Text Approach (STA) to Influence Change in secondary School Two Students' Attitude towards Learning Chemical Equilibrium in Keffi, Nasarawa State

The study investigated the attitude of senior secondary two (SSI1) students in Keffi zone in Nasarawa State towards the use of Structured Text Approach (STA) in learning chemical equilibrium. Ex post facto research design was employed. The population of the study comprised all the 1,005 SSn students offering chemistry in public and private senior secondary schools in Keffi zone. Stratified random sampling technique was used to select 50 students from three public and three private senior secondary schools out of the 15 in the study area. This gave a total sample size of 300 students. Two instruments: Structured Text in Chemical Equilibrium (STCE) and Structured Text Approach Attitude Questionnaire (STAAQ) were used to collect data. Simple percentage and chi-square statistical techniques were used to answer the research question and test the hypothesis respectively. The major finding was that the attitude of the sampled chemistry students towards learning of chemical equilibrium using STA was positively influenced. Based on this finding, it was recommended that this approach should be learnt and used by chemistry teachers to teach this difficult concept of chemical equilibrium to help students overcome their fear and negative attitude towards mastering the concept.
