Abstract The GI-GI learning model is a combination of the Group Investigation and the Guided Inquiry model. The research aimed to examine the effect of the GI-GI learning model on collaboration and students’ science process skills. The type of research carried out was Quasi-Experimental and used a post-test only control group design and purposive sampling covering four high schools in the Besuki Residency, two classes as the experimental class and the control class. The research instrument used tests, observations, and documentation. The results showed a significant effect of the GI-GI learning model on collaboration and students’ science process skills. This research implies that the GI-GI learning model can condition students to research in groups to interact actively with friends and educators to exchange opinions, knowledge, or experiences, find and solve problems, and hypothesize through investigation, exploration, and discussion outside or inside in class.

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.

This study was conducted to determine the effect of buzz group discussion learning methods on the activeness and learning achievement of physics in class VIII of SMPN 4 Praya Barat Daya 2015/2016 Academic Year. The type of research used in this study is a kind of quasi-experimental research. The population in this study were all eighth-grade students totaling 38 people consisting of class VIII A totaling 20 people as the experimental class and class VIII B totaling 18 people as the control class with the sampling technique used was a saturated sampling technique. The instruments used are valid observation and test sheets both in content, construct, and empirical with a value of 3.34; 3.40; and 3.23, and reliable with the value of αCronbach = 0.608. The results of this study were also able to influence the achievement of learning physics. Based on statistical calculations using the ttest test, the value of tcount = 23.00 is greater than t table = 2.02 (t count = 23.00> t table = 2.02). Thus, it can be concluded that there is the influence of buzz group discussion learning methods on the activeness and learning achievement of physics in class VIII Praya Barat Daya SMP 4 2015/2016 Academic Year.
