Abstract

The study examined the effects of audio -visual technological aids on chemistry students' achievement in senior secondary schools in Nsukka education zone of Enugu State, Nigeria. The study employed a pre-test-post-test, control group quasi experimental research design. Two research questions and two null hypotheses were formulated to guide this study. The population of the study comprises of all the SSI Chemistry students in public secondary schools in Nsukka education zone. The sample size was 100 SSI Che mistry students comprising of 48 male and 52 female students of two intact classe s. Purposive sampling technique was used to select two co-educational schools which one were assigned to experimental group and other to control group. The instrument used for data collection was a 25 -item Chemistry achievement test (CAT). Mean, Standard Deviation and ANCOVA were used for data analysis. Result revealed that the mean score for the Chemistry students exposed to lessons with audio-visual technological aids achieved higher compared to the mean score of those counterpart not exposed to lessons with audio- visual technological aids. The study recommended that Chemistry teachers should keep pace with development trend by learning and using new technologies (audio-visual) in teaching and learning.

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.

Effects of Immediate and Delayed Feedback Modes of Assessment on Students' Achievement and Retention in Chemistry

Chidinma A. Ezeano, Obinna T. Asogwa

The purpose of the study was to ascertain the effect of immediate and delayed feedback modes of assessments on students' Achievement in Chemistry. Four research questions and four null hypotheses guided the study. Pretest-posttest non-equivalent control group quasi-experimental research design was adopted for the study. The population for the study comprised of 2,296 senior secondary class two (SS II) students offering chemistry in 21 co- educational secondary schools of Enugu Education Zone in Enugu State. A sample of 144 SSII students drawn from 3 public secondary schools in the zone was used for the study. A purposive sampling method and simple random sampling techniques were employed in the study. The instrument for data collection was chemistry achievement test (CAT) which consisted 40 test items. The instrument was validated by three experts; one expert in Measurement and Evaluation and the other two in Science Education. The reliability of was determined using Kuder-Richardson's formula-20 (K-R20) and the reliability coefficient obtain was 0.82. The instrument was administered as pretest and posttest. Mean and standard deviation were used to answer the research questions while the Analysis of Covariance (ANCOVA) was used to test the hypotheses at 0.05 level of significance. The Statistical Package for Social Science (SPSS) was used for all the analyses. The result of the analysis revealed that students who received immediate and delayed feedback modes of assessments achieved better than students who did not receive feedback. It was also revealed that students who received delayed feedback had higher achievement scores than students who received immediate feedback. Moreover the result showed that gender had no significant effect on students who received immediate feedback. The study recommended that chemistry teachers should ensure that students are given delayed feedback to enhance their achievement in chemistry.

Effect of Audio-Visual Materials on Senior Secondary School Students' Achievement in Chemistry in Agbani Education Zone Enugu State

Nkiruka J. Iyida, Charles U. Eze

The study investigated the effect of audio -visual materials (AVM) on senior secondary school students' achievement in Chemistry in Agbani education zone, Enugu State. Two research questions and two null hypotheses guided the study. Quasi -experimental non- equivalent control group design was adopted for the study. The sample size for the study was a total of 148 SS II chemistry students, (75 male and 73 female). On e instrument, Chemistry Achievement Test (CAT) was developed, validated and reliability coefficient (.82) before using it for data collection. The research questions were answered using mean and standard deviation. The null hypotheses were tested at (P < 0.05) using analysis of covariance. The result of data analysis showed that there is a significant difference between the mean achievement scores of students taught using AVM and their counterparts taught without AVM; the students taught using AVM achieved more. Also there is a significant difference on the mean achievement scores of male and females taught using AVM. The female achieved higher than their male counterparts. Among the educational implications of the findings is that since use of AVM increased the achievement levels of students in chemistry, chemistry teachers should integrate its use in the teaching of chemistry. Among the recommendations made based on the findings is that in -service training's in the form of seminars and workshops should be organized by government and relevant professional bodies like STAN to educate and sensitize the teachers on the use of AVM for their lesson delivery
