Effect Of Concept Mapping And Standardized Based Testing On Science Students' Academic Achievement In Senior Secondary Schools In Imo State, Nigeria:-Akanwa, Ursula N

Abstract The study examined the Effects of Concept Mapping and Standardized-Based Testing on Science Students' Academic achievement in Senior Secondary Schools in Imo state. Two research questions and two null-hypotheses were formulated to guide the study. The research design adopted was the quasiexperimental non-randomized pretest and post-test control group. The population for the study comprised all the 5,763 Senior Secondary School Two (SS II) Science students in all the Secondary Schools within Ehime Mbano Local Government Area of Imo State. The sample size comprised 120 Science students which made up of 58 experimental and 62 control groups. Purposive sampling technique was used to select two secondary schools out the fifteen Secondary Schools. The research instrument was Agricultural Science, Biology and Physics Standardized Test (ASBPST) adapted from NECO past questions. The instruments were validated by experts in Measurement and Evaluation, Department of Science Education, Michael Okpara University of Agriculture, Umudike, to establish its validity and test re-test method was used to establish the reliability of the instrument which yielded a reliability index of 0.74 calculated using the Kuder-Richardson Formular 20. Mean and standard deviation were used to answer the research questions while the Analysis of Covariance (ANCOVA) was used for testing the hypotheses at a significance level of O. 05. The findings revealed that science students taught Biology, Physics and Agricultural Science with concept mapping and assessed using standardized based testing performed better than their counterpart taught without concept mapping but assessed using standardized based testing, that concept mappmg a h. ent in science subjects.
