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.

INTRODUCTION: Low levels of hamstring flexibility may trigger certain acute and chronic pathologies and injuries. Poor flexibility is observed among teenagers and several authors have recommended the use of specific programs in this population to improve flexibility levels. The Pilates Method (PM) may be an appropriate intervention to achieve this purpose and has rarely been used with this population. Objective: Study was to assess changes in the flexibility of hamstrings after running a didactic PM unit for high-school students.METHODS: This research was developed through a quasi-experimental design. The sample consisted of 66 high-school students divided into experimental group (EG=39) and control group (CG=27). The intervention was carried out 2 times a week for six weeks. Each session lasted 55 minutes divided into three parts: warm-up, main part and cool down. Hamstring flexibility was assessed using the toe-touch test. Paired Student t-test and t-test for independent samples were applied. The size of the effect (d) was determined.RESULTS: The EG showed significant provident in hamstring flexibility (+3.54±3.9cm). The effect size was low (d>d>0,2<0,53), which means that a small proportion of participants improved their results. The control group did not have significant changes after the intervention. In the experimental group, both boys (+3.38± 3.7cm) and girls (+3.85 ± 4.2cm) showed significant improvements. The effect size was low for boys (d>d>0.2<0.53), which means that a small proportion of participants improved their results, and high for girls (d>1.15) which means that a large proportion of participants improved their results.CONCLUSION: This study showed that six-weeks of Pilates training in Physical Education classes has significantly improved the hamstrings flexibility among adolescents.
