EFFECT OF BALL-AND-STICK MODEL INSTRUCTIONAL STRATEGY ON SENIOR SECONDARY SCHOOL II STUDENTS’ INTEREST AND PERFORMANCE IN STEREOCHEMISTRY IN TARABA STATE

Abstract

This study determined the effect of ball-and-stick model on senior secondary school II students’ interest and performance in stereochemistry in Taraba State, Nigeria. The population of the study consisted of 530 senior secondary school two students in twenty secondary schools in Bali Education Zone. Quasi-experimental design of pre-test post-test was adopted for this study. Intact classes in the schools were assigned to experimental group (Ball-and-Stick Model) and Control Group (Expository Method). The sampling of schools was based on simple random sampling technique by balloting with the numbers of students in the experimental group thirty-five 35 and forty-five students in the control group. The validity of the Instruments was determined by chemistry education Experts. The instruments Stereochemistry Performance Test (SPT) and Stereochemistry Interest Inventory (SII) reliability determined using Kuder Richardson 21 coefficient 0.81 and Cronbach Alpha coefficient 0.79 respectively were used. The method for data collection administered was pre-test administered for forty minutes using the instrument SPT and SII scores were recorded after the treatment for four weeks post-test was administered and data were collected using the same instrument SPT and SII scores recorded. Data collected were analyzed using mean, standard deviation to answered the Research Question and t-test was used to answer the Research Hypotheses at 0.05 level of significance. The results indicated that a significance difference exists between students taught stereochemistry using ball-and-stick model and those taught using expository method. It is recommended that used of ball-and-stick model and relevancy of the teaching materials should be put to practice by teachers in order to bring forth understanding in the concept and that Government and Proprietors should ensure the provision of ball-and-stick model in schools.
