    The Effects of Structured Text Approach on Chemistry Students' Achievement in Chemical Equilibrium
    (Department of Chemistry Education,Nasarawa State University Keffi., 2015-03-10) Eniayeju, P.A.; Tanko, Jibrin Abdullahi.
    The study investigated the effect of structured text approach on the achievement of senior secondary students in chemical equilibrium. The sample comprised two groups of students (N=60) drawn from two different schools in Keffi metropolis. The equivalence of the groups was determined using a pretest in chemical equilibrium. Three instruments were developed and validated the investigator for data collection. The instruments are Pre-Test in Chemical Equilibrium (PRTCE), Post-Test in Chemical Equilibrium (POTCE)andStructured Text in Chemical Equilibrium (STCE).The treatments, structured text approach and demonstration method were randomly assigned to the two groups selected for the study. The experimental and control groups were taught for four weeks after which the post test was administered. The likert scale questionnaire was administered to the experimental group after instruction. The results of the t-test analysis showed that the experimental group mean score (11.33) was significantly better than that of the controlled group (8.57)at p?. 05. Analysis of the questionnaire using chi-square statistics showed that the attitudes of students exposed to Structured Text Approach on chemical equilibrium is favourable.
