The study examined the effect of Context Based Learning (CBL) and gender influence on chemistry students’ acquisition of Integrated Science Process Skills (ISPS). Two research questions guided the study. This study used a quasi-experimental research design with a sample of 192 participants who had an average age of 15. Three instruments were used in data collection. Data were analyzed using mean and standard deviation. The results showed that Context Based Learning (CBL) had more effect on students’ Integrated Science Process Skills (ISPS) in chemistry. Students exposed to CBL pedagogy acquired more Experimental Skill (EXPS) than Analyzing and Interpreting Data Skill (ANIDS) with Identifying and Controlling Variables Skill (ICVS) the least. Also, students exposed to Conventional Strategy (COS) excelled in ANIDS, more so than Identifying and Controlling Variables Skill (ICVS) with Experimental Skill (EXPS) the least acquired. The influence of gender on ISPS was observed in favour of females. The study concluded that gender imbalance exists in all spheres of life, therefore, chemistry teachers should help students in acquiring integrated science skills using the two approaches to enhance male and female students’ knowledge, values, and skills creatively in secondary school chemistry. The study recommends the teaching of students on everyday activities that foster gender balance in Lagos State secondary schools.

Effective teaching of Biology practical entails the use of specimens. However, in Nigeria, some natural specimens are difficult to obtain when needed, hindering the learning and application of science process skills. Consequently, teachers resort to pictorial representation of specimen and to online prints for Biology practical instructions. Another possible alternative less discussed is the use of synthetic or artificial specimens. The goal of this study, therefore, was to examine the effect of using synthetic and natural specimen on practical skills- process skills acquisition and application in Biology practical in secondary schools. It sought to determine the efficacy of using synthetic specimens to complement or substitute for natural specimens in teaching Biology practical. The study employed the pre-test, post-test, control group, quasi- experimental design. A total of 212 senior secondary school (SS II) Biology students in six selected government-owned high schools in Moba and Ijero Local Government Area of Ekiti state, Nigeria, were randomly selected for the study. The schools were paired and assigned to two experimental groups (using synthetic and natural specimens) and a control group (using conventional drawings). Eight instruments were employed for the study and used at treatment stage. Data collected were analyzed using Analysis of Variance (ANOVA), Analysis of Covariance (ANCOVA) and Multiple Classification Analysis (MCA). The results showed that there was a significant effect of synthetic specimens and natural specimens on the proficiency of the students in basic science process skills acquisition (F = 60.470, P<0.05). However, the mean gain of 3.884 which existed between the two groups showed that natural specimens were slightly more effective than synthetic specimens. The results also showed a significant effect for the use of synthetic specimens on process skills acquisition and applications of Biology concept among the students (F = 74.773, P<0.05). The study concluded that synthetic specimens are equally effective as natural specimens in improving the acquisition and application of basic science process skills of students in Biology.

Descriptive Survey

<em>Science process skills are central to the acquisition of scientific knowledge which is useful in problem solving in our immediate environment. In Nigeria, most secondary school students’ performances in chemistry in the West Africa Senior School Certificate Examination (WASSCE) are generally low which could probably be attributed to lack or poor exposure to science process skills. The study therefore investigated the influence of gender, and class size on Chemistry students’ acquisition of science process skills. The design adopted for the study was descriptive survey design. The sample comprised of 720 students drawn through multi-stage random sampling from Adamawa and Taraba States in Nigeria. The research instrument was Science Process Skills Knowledge Test in Chemistry’ (SPSKTC). The study indicated that gender have negligible influence on students’ acquisition of science process skills; while large class size have great influence on students’ acquisition of science process skills. The study concluded that most students in Nigerian schools experience difficulty in the acquisition of science process skills. Based on the findings, it was recommended that there should be reduction of student-teacher ratio in schools and training of teachers on science process skills to enable teachers adopt methods that lead students to have the appropriate skills.</em>

<span>This study investigated the comparative effectiveness of pedagogical pattern of running a course and talk-chalk methods on senior secondary school students’ achievement in waves. It is triggered by reports of persistent students’ low achievement in physics contributed largely by students’ poor performance in waves-related items. It adopted the quasi-experimental pretest-posttest control group design. Three research questions and hypotheses guided the study. There were 216 students who participated in the study. Physics Achievement Test (PAT) containing 50 multiple-choice researcher-developed items were used as instrument for data collection. Mean and standard deviation were used to answer the research questions while ANCOVA was used to test the hypotheses at 0.05 level of significance. Results showed that: the pedagogical pattern of running a course method was superior method in fostering students’ achievement in waves; female students achieved higher than male students using pedagogical pattern of running a course strategy to teach waves; and there was no significant interaction effect of teaching methods and gender on students’ achievement in waves. From the findings, it was recommended that the pedagogical pattern of running a course strategy should be used in teaching physics in secondary school education system and in training of teachers.</span>

Attitude Toward Science

Science learning outcomes such as science process skills and attitudes toward science are still important issues in science education. In this study the researchers tried to get a picture of the students' learning outcomes to get input on the learning process of science in the coastal area. As an initial study of the development of maritime-based contextual science learning media, the purpose of this research is to know the extent of science process skill level, attitude toward science, and academic achievement of students in coastal area. There were 114 students of the 8th grade of four lower secondary schools in Merbau Island participated as respondents in this study. Instruments used in data collection are science process skills tests and attitude toward science questionnaires for lower secondary school students. The results showed that 8th grade lower secondary school students in Merbau Island had high attitude toward science. On the contrary, the science process skills and academic achievement of their science are relatively low.
