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>

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.

Development and acquisition of science process skills (SPS) is necessary for understanding of science and offering of solutions to scientific problems. Assessing SPS acquired by students is key to monitor its development and acquisition. The study used descriptive survey to find out the nature of SPS developed and acquired by final year senior high school chemistry students. The study used parametric achievement test instrument called Students’ development of science process skills index Test.  The test was conducted for 904 students drawn from 20 out of 36 Senior High Schools in the central region of Ghana, that offer elective science courses. The schools and students were sampled from 17 out of 20 districts in the central region of Ghana via multi-stage sampling technique taking into cognizance the school grades categories in Ghana comprising Grades A, B and C. The analysis of the result shows that students acquired mainly basic SPS like Observing, Communicating, and integrated SPS like Interpreting. However, SPS like Classifying, Hypothesising, Controlling Variables and Experimenting were hardly developed/acquired. The acquisition of SPS was also found to depend significantly on the type of school attended and gender. It is recommended that more opportunity be given to practice and access SPS, particularly, the integrated SPS.

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.

The study was aimed to investigate the effectiveness of teaching strategy based on Multiple Intelligences (MI) theory to improve multiple intelligences and science process skills of junior high school students in Indonesia. The study used quasi experimental design and the effectiveness of the teaching strategy was evaluated by pretest-posttest-control-group design. The samples consisted of two schools selected by Stratified Random Sampling. The experimental group (n=63) was taught using the MI strategy while the control group (n=61) was taught using the traditional strategy. This study was conducted in 12 weeks. Data were obtained from multiple intelligences test, science process skills test, and observation sheets. The hypotheses of student multiple intelligences and science process skills were tested using Wilcoxon’s Signed Rank Test and ANOVA test. The results indicated that students who were instructed by using MI strategy improved on four specific types of multiple intelligences namely visual spatial, intrapersonal, kinesthetic, and musical intelligences. However, the interpersonal logic remains unchanged, while the mathematical logic decreases after treatment. Also, these showed an improvement of the science process skills, specifically in the questioning ability.
