Impact of Brain-Based Instructional Strategy on Academic Performance of Deaf Students in Mathematics in Oyo School of Handicapped, Nigeria
This study investigated the impact of brain-based instructional strategy on academic performance of<br />students who are deaf or hard of hearing (D/HH) in mathematics. A pre-test, post-test, control group<br />quasi-experimental design was adopted with a 2 x 3 x 2 factorial matrix. The sample size of 41 students<br />who are D/HH were randomly selected in the school. Two intact classes each were randomly assigned<br />to the experimental group (Brain-Based Instructional Strategy-BBIS) and the Control Group<br />respectively. The instruments used were, Mathematics Attitude Questionnaire (r = 0.81), Cognitive<br />Style Test (r = 0.80), and Mathematics Anxiety Rating Scale (r = 0.81). Three research questions<br />guided the study. Data obtained were analyzed using descriptive statistics of mean scores and standard<br />deviations to explain and compare pretest and posttest scores of the experimental and control groups in<br />all the criteria measured. Brain-based instructional strategy was more effective at improving students’<br />attitude to mathematics than the conventional method. The findings of the study also indicated that<br />tension and test-phobia which normally permeates the teaching-learning process of mathematics was<br />highly reduced due to the optimal use of diverse brain compatible instructional materials among<br />students who are D/HH.
