The teaching and learning of building technology in technical colleges seems to be characterised by poor academic achievement and retention of concepts. This called for the search for innovative teaching approaches like the edutainment instructional approach. The study was therefore conducted to determine the effect of edutainment instructional approach on students’ academic achievement and retention in building technology in technical colleges. Two research questions guided the study and two null hypotheses were tested at 0.05 level of significance. The study adopted the quasi-experimental design in which there were pre-test and post-test in the experimental and control groups. The population of the study comprised all the 946 senior technical II (ST2) students offering building technology in the six public technical colleges in Akwa Ibom State. Purposive sampling technique was used to select four technical colleges in the study area. Three instrument namely: edutainment lesson plans, conventional lesson plans and building technology achievement test (BTAT) were used in the study. Three experts validated the instrument. Test-retest reliability of the instrument which yielded an index of 0.87 obtained using Pearson product moment correlation coefficient. The data collected for the study were analysed using the mean scores and standard deviation for answering the research questions while hypotheses were tested with the analysis of covariance (ANCOVA) at 0.05 level of significance. The study found that: the edutainment instructional approach enhanced students’ academic achievement and retention in building technology more than the conventional lecture method. There was significant difference in the academic achievement and retention of students in building technology between the two groups. The significance was attributed to the experimental group which obtained a higher mean score in the post-test and retention test. It was recommended that: teachers of building technology in technical colleges in Akwa Ibom State should adopt edutainment instructional approach in the teaching of building technology courses in order to enhance students’ academic achievement and retention in building technology.

We aimed to contribute to a shift in higher education teaching and learning methods by considering problem-based learning (PBL) as an approach capable of positively affecting students from a geology and environment (GE) curricular unit. In a convenience sample from a Portuguese public university, two groups of students were defined: (1) an experimental group (n = 16), to which an intervention program (IP) based on PBL was applied, and (2) a comparison group (n = 17), subjected to the traditional teaching approach. For nine weeks, students subject to the IP faced four problem scenarios about different themes. A triangulation of methods was chosen. The study involved two phases: (1) qualitative (sustained on content analysis of driving questions raised by students, registered in a monitoring sheet) and (2) quantitative (quasi-experimental study, based on data from a prior and post-test knowledge assessment). The qualitative results point to the development of more complex cognitive-level questioning skills after increasing familiarity with PBL. The data obtained in the quantitative study, which included both a “within-subjects” and a “between-subjects” design, show higher benefits in the experimental group, documenting gains in terms of scientific knowledge when using the PBL methodology.

This study was developed and conducted to test the effect of cognitive restructuring in the management of mathophobia (that is, Mathematics anxiety) among secondary school students in Khana Local Government Area of Rivers State, Nigeria. To guide the study, two research questions and two null hypotheses were formulated for testing at 0.05 level of significance. In executing the study, the pre-test, post-test, and control group experimental research design was adopted using a randomized sample of 120 SS2 students drawn from three public secondary schools only. The researchers developed an instrument titled “Mathematics Diagnostic Questionnaire” (MDQ) which was adequately assessed for validity and reliability and was used in collecting pre-test and post-test data for the cognitive restructuring and control groups. Data analysis was done using mean, and standard deviation for the research questions, while independent sample and paired sample t-test were used for the hypotheses. The result obtained showed that the cognitive restructuring was significantly effective in the management of mathophobia among secondary school students. There is a slight reduction in the effect of cognitive restructuring during follow-up; there is a statistical significant difference in the mathophobic level of students treated with cognitive restructuring and those in the control group. Based on the major findings, recommendations were made among which is that functional guidance and counselling centers be established at all educational levels and be manned by professional counsellors who are competent in cognitive restructuring techniques to assist those who have mathophobia and other maladaptive behaviours. Suggestions for further study were made.

Chemistry is one of the scientific disciplines considered difficult for students to understand its microscopic and macroscopic concepts. Students also claim that this discipline is tedious and complicated. They are unable to connect what is shown in the visual structure to the process and phenomenon. In the context of self-motivation among university students, there is a higher chance of expanding the stimulation of learning. This study aimed to improve self-confidence and the mastery of concepts of chemistry teaching students using problem-based learning. The quasi-experimental method was used with the design of the non-equivalent pre-test-post-test control group. The population included all students in the electrochemistry class at Lampung University in 2019. The purposeful sampling technique employed divided the sample into two groups. The first group was called Class A and was considered as the experimental class - using problem-based learning -. The second group, Class B, was recognized as the control class - using the conventional model in which the teacher applied the speech method in the delivery of materials during the class -. Class A's self-confidence and mastery of concepts have a higher nGain value than class B, and the result of the effect size is that class B has a more significant effect than class A. Based on the outcome, one can conclude that problem-based learning has a significant influence on improving self-confidence and mastery of concepts on the electrochemical theme.

Terdapat banyak model pembelajaran yang diterapkan untuk menganalisis kemampuan argumentasi ilmiah siswa. Namun, belum banyak model yang diintegrasikan dengan pembelajaran berbasis simulasi online untuk meningkatkan kemampuan argumentasi ilmiah siswa. Padahal, saat ini ada banyak website simulasi online yang diterbitkan oleh lembaga pendidikan atau universitas di tingkat internasional dan jarang digunakan dalam penelitian. Penelitian ini mengintegrasikan model pembelajaran inovatif dengan pembelajaran berbasis online simulation untuk meningkatkan kemampuan argumentasi ilmiah siswa. Website simulasi yang digunakan adalah Edu-media simulation. Dalam website ini ada banyak simulasi fisika yang disediakan, tetapi belum banyak penelitian yang menerapkan simulasi ini. Penelitian ini dilakukan dengan kuasi eksperimen yang terdiri dari satu kelas eksperimen dengan sampel 25 siswa kelas XI MIA 3 di SMA N 1 Prambanan Yogyakarta. Argumentasi ilmiah siswa diukur melalui instrumen tes uraian. Data argumentasi ilmiah siswa dianalisis menggunakan paired sample t-test  dan pola argumentasi Toulmin (TAP). Hasil penelitian menunjukkan bahwa PBL berbantuan edu-media simulation dapat meningkatkan kemampuan argumentasi ilmiah siswa baik secara kuantitatif maupun kualitatif. Ini ditunjukkan dengan nilai t value -11.051 < -1.711 bahwa terdapat perbedaan nilai rata-rata argumentasi pada pre-test (17) dan post-test (47). Dalam hal ini, siswa sudah mampu membuat klaim yang tegas dengan menyajikan bukti dan alasan yang mendukung klaim. Analyzing students’ scientific argumentation skill in optic: Problem-based learning assisted edu-media simulation AbstractThere are many learning models applied to analyze the ability of students' scientific argumentation. However, not many models have been integrated with online simulation-based learning to improve students' scientific argumentation skills. In fact, there are currently many online simulation websites published by educational institutions or international universities and rarely used in research. This research integrates innovative learning models with online simulation-based learning to improve students' scientific argumentation skills. The simulation website used is Edu-media simulation. In this website there are many physics simulations provided, but not many studies have applied this simulation. This research was conducted with a quasi-experimental consisting of one experimental class with a sample of 25 XI MIA 3 graders in Prambanan High School 1 Yogyakarta. Students' scientific arguments are measured through a description test instrument. Students' scientific argumentation data were analyzed using paired sample t-test and Toulmin argumentation patterns (TAP). The results showed that PBL assisted by edu-media simulation can improve students' scientific argumentation ability both quantitatively and qualitatively. This is indicated by the value of t value -11.051 <-1.711 that there are differences in the average value of argumentation in the pre-test (17) and post-test (47). In this case, students have been able to make assertive claims by presenting evidence and reasons that support the claim.
