The major purpose of this study was to determine the effects of field experiences on students’ knowledge of process of science and biology achievement. The design of the study was experimental, 2 x 2, pre-test, post-test control group design. The sample of the study consisted of 100 biology students in two intact classes. Four research questions were raised and collapsed to four hypotheses. The first three hypotheses were tested with t-test statistic at 0.05 level of significance. The fourth hypothesis was tested with Pearson Product Moment Correlation Statistic. The major findings of this study included: a significance difference in process of science scores between pre-test and posttest of field trip students; a significant difference in process of science test scores between students exposed to field trip experiences and those who were not exposed; a significant difference in biology achievement test scores between students exposed to field trip experiences and those who were not; and a strong correlation between process of science score and biology achievement score. It was concluded that field trip experiences enhanced students’ understanding of process of science, improved students’ attitude towards biology and significantly influenced their biology achievement.

This study examined the effects of computer animation instructional package on secondary school students’ achievement in practical biology in Ilorin, Nigeria. The study adopted a pre-test, post-test, control group, non-randomised and nonequivalent quasi-experimental design, with a 2x2x3 factorial design. Two intact classes from two secondary schools were purposively sampled. The instruments used were Biology Practical Achievement Test (BPAT) for data gathering and Computer Animation Instructional Package (CAIP) as the treatment instrument. The reliability coefficient of BPAT was determined using the Pearson Product Moment Correlation and was found to be 0.91. Two research questions and two hypotheses were formulated in the study. The hypotheses were tested with t-test statistics at a significance level of 0.05. The study concluded that CAIP significantly improved students' achievement in practical biology. The researchers recommend that biology teachers should employ computer animation instructional packages to teach the practical aspects of photosynthesis among other biology topics.

This study examined the effect of the 5E instructional model on Physics students’ academic achievement based on gender and students’ ability. The study employed a quasi-experimental design using the pre-test, post-test and delayed-post administered instruments to the experimental and control groups. The study involved two instructional strategies (5E instructional model and traditional teaching). Instruments known as Physics Students’ Academic Achievement Test (PSAAT) and Delayed Post Test (DPT) were used to gather data for the study. Mean scores, standard deviations and normalized gains were used to analyses data while ANCOVA and independent-sample t-test were used to test the hypothesis at the 0.05 level of significance. A significant difference was found between Physics students instructed with the 5E instructional model and those taught through the traditional classroom. Similarly, a significant difference was found between Physics high-ability student in the 5E instructional group and those in the traditional group. However, a non-significant difference was found between Physics low-ability students in the experimental and the control groups. Similarly, a non-significant different was found among gender concerning pre-test and post-test means scores. However, a significant difference was found among gender in favor for the male students. The study recommended that Physics teachers wanting to improve their students learning outcomes should adopt the 5E instructional model.

This study aims to assess the effectiveness of using Physics Education Technology (PhET) interactive simulations in improving students' understanding of energy conversion and conservation at Tuobodom Senior High and Technical School, with a focus on comparing female and male students. A total of 45 students (male = 29, female = 16) were selected using purposive sampling and taught using both traditional methods and PhET simulations, with their understanding evaluated through pre and post-intervention tests. Data was analyzed using descriptive statistics and t-tests. There was a significant pre-intervention score difference between males (15.88) and females (8.25) with a p-value of 0.00, however post-intervention scores were similar for both groups (males 10.88, females 12.62). The study found that PhET simulations effectively promote gender equity by narrowing the performance gap which is likely to improve student’s interest in science, technology, engineering and mathematics (STEM). The findings of the study shows that PhET interactive simulation improves students' conceptual understanding of energy conversion and conservation.
