This paper examines the efficacy of two modes of digital learning object package on students’ achievement and interest in rocket and satellite in post covid’19 Era. The study adopted Quasi-Experimental research design. A sample of 132 SS3 physics students selected using purposive sampling technique. The instruments used for data collection were Rocket and Satellite Achievement Test (RSAT) and Students Interest Questionnaire (SIQ) developed by the researchers. The reliability coefficient indices of 0.88 and 0.83 for RSAT and SIQ were obtained using Kuder-Richardson 20 (KR-20) formula and Cronbach Alpha. The data obtained were analyzed using mean and standard deviation to answer the research questions and analysis of covariance (ANCOVA) to test the Null hypotheses. Findings revealed that DLO with tutor-led instructional model significantly promotes students’ achievement and interest in rocket and satellite compared to DLO self-paced instructional model. Gender had some influence on physics students’ achievement and interest in Rocket and Satellite but not statistically significant. Based on the findings it was recommended amongst others that: Physics teachers should adopt the use of DLO with Online teaching packages (especially using, tutor-led instructional model) to enhance students’ achievement and interest in the Rocket and Satellite.

The main purpose of this study is to explore students’ misconceptions of science concepts in secondary school biology in Gusau, Zamfara State. Three research questions and one null hypothesis guided the study. The study adopted a descriptive survey research design. 1750 senior secondary school three (SS3) biology students of 2020/2021 session in all the 25 public secondary schools in Gusau, Zamfara State, formed the population for the study. The sample size of 220 senior secondary three (SS3) students was used for the study. Simple random sampling and proportionate stratified random sampling techniques were used in composing the sample. Questionnaire on the source of students’ misconception of science and biology concepts (QSSMSCB) and Students’ Conception Test (SCT) having 20 objective items developed by the researchers to measure students’ conception in biology. Frequency and percentage were used to answer all the research questions, and Chi-square was used in testing the null hypothesis of the study. The study found that: the heart, photosynthesis, fertilization, peristalsis, and gamete were the common misconceptions among secondary school biology students in Gusau; biology textbooks, teachers, and traditional/religious beliefs were sources of misconceptions of science concepts among secondary schools in Gusau; and finally, the influence of gender on secondary school students’ conception of biology in Gusau is not statistically significant. Based on the findings, the following recommendations were made, among others: biology teachers should learn how to probe into students’ conceptions in a bit to help them grasp the correct/clear explanation (i.e., conceptual understanding) of to-be-learnt concepts for better understanding.
