Abstract

This research investigated the effect of Peer Instructional Strategy (PIS) on the academic achievement of Secondary School Biolo gy Students in Enugu Education z one of Enugu State. Two research questions and two hypotheses guided the study. The study employed non-equivalent control group design involving 528 (227 male and 301 female) SSII Biology students drawn from six randomly selected co -educational schools out of the ten secondary schools in Enugu Education z one that met the inclusion criteria. Two intact classes from each of the six schools (twelve classes) were randomly assigned to either Peer Instructional Strategy and Expository Method group by balloting. U sing the assigned method for each group, trained research assistants taught the same content to the respective groups, simultaneously. The instrument for the study was a researcher -made Biology Achievement Test (BAT), validated by three experts, and pilot tested. Pearson Product Moment Correlation Coefficient was used to carry out test-retest reliability of the instrument, r = 0.74. The BAT was administered (pretest) before the interventions, after 4 weeks long intervention (post -test).. To avoid distribution bias; scores of forty -four students who completed the study procedures and took all the appropriate tests were randomly drawn from each of the twelve intact classes through software randomization. The scores were processed for data a nalysis. Statistical tools of mean and standard deviation were used to answer the research questions while Analysis of Variance was used to test the hypotheses at.05 level of significance. The researcher concluded that P IS improves the academic achieveme nt and of both ma le and female secondary school Biology students better than the expository Method.

Effect of Peer Instructional Strategy on Academic Retention of Senior Secondary School Biology Students in Enugu Education Zone

Matthew D. Idoko

The study examined the effect of Peer Instructional Strategy (PIS) and expository method (EM) on the retention of Secondary School Biology Students. The purpose of the study was to investigate the effect of peer instructional strategy relative to expository method on the retention of secondary school Biology students. The area of the study was Enugu Education Zone of Enugu State. Two research questions and hypotheses guided the study. The study was a quasi-experimental research with pretest-posttest, non-equivalent groups research design; involving 528( 227 male and 301 female senior secondary school 2 Biology students drawn from six randomly selected co -educational schools out of the ten secondary schools in Enugu Education z one that met the inclusion criteria. Two intact classes from each of the 6 schools were randomly assigned to either PIS or EM group by balloting. The instrument for the study was a researcher -made Biology Achievement Test (BAT), validated by three experts. C ontent validity was ensured using text blueprint. The Pearson's product moment correlation c oefficient was used to carry out test -retest reliability of the instrument, r = 0.74. The BAT was administered 2 weeks after posttest. The results showed that PIS group significantly performed better than EM group in terms of academic level of retention. The researcher recommends PIS should be used in teaching and learning of Biology.

Effects of Inquiry Based Teaching Strategy and Gender on Secondary School Students' Academic Achievement in Stereochemistry in Enugu Education Zone

Cynthia O. Omeje, Mary I. Ugwu

The students' consistent low performance in internal and external examinations undermined the efficacy of chemistry teachers' methods of instruction. Thus, the purpose of the research is to find out how inquiry-based learning can impact students' academic achievement in stereochemistry in Enugu education zone. The study was guided by two research questions and three research hypotheses. The study employed a pretest-posttest non-equivalent control group design. 4,532 SS2 Chemistry students made up the study's population. A combination of random and purposive sampling procedure was used to select 96 students. While the control group received instruction via lectures, the experimental group was taught using an inquiry-based teaching strategy. The Chemistry Achievement Test (CAT) was the instrument used for data collection, and its reliability index was evaluated using Kuder-Richardson's formula-20 which yielded coefficient of 0.84. The mean, standard deviation, and analysis of covariance were used to analyze the data. The findings demonstrated that students exposed to the inquiry-based teaching strategy outperformed their peers who received instruction via lectures. For improved students' achievement, it was recommended that Chemistry teachers should use inquiry based teaching strategy when teaching chemistry.

Social Competence and Gender as Predictors of Junior Students' Academic Achievement in Basic Science in Enugu State

Josephine N. Okoli, Bamidele A. Ikusika

The study investigated social competence and gender as predictors of junior secondary school students' academic achievement in basic science in Enugu state. Three research questions and three null hypotheses guided the study. The predictive correlation design was adopted for the study. The population of the study was 9,192 upperbasic science students in Enugu state. The sample size for the study was 1000 students drawn using multi-faceted sampling procedure involving purposive and random sampling techniques. The instrument for data collection was Students ' Social Competence Scale. The students' achievement scores in Basic science were obtained from the teachers' score folder. Data generated from the study was analysed using simple and multiple linear regressions. The findings of the study revealed among others that 1.6% and 1.1% of the variance in achievement in Basic science was attributed to social competence and gender of Basic science students' respectively. Also, achievement scores in Basic science were significantly predicted by social competence and gender, individually and jointly. It was recommended that basic science teachers should ensure that the atmosphere within the classroom is gender friendly enough, making sure that both male and female students have a conducive social atmosphere to be actively involved in learning Basic science.
