To ascertain the accuracy and usability of the instructional model, it must be verified by a professional or expert in the area of the subject content. The automated model of the human heart (3-DAMHH) has to be inspected and verified by a qualified biology education expert to ascertain its accuracy while the usability has to be verified by an educational technology expert. Hence, it is needed to determine the experts’ validation of 3-DAMHH to teach a Biology concept in Ilorin, Nigeria. Two instruments were developed: Educational Technology Experts’ Rating Scale and Biology Education Experts’ Rating Scale. Percentage scores were used to answer research questions. Findings of this study revealed the percentage score of the rating for the validation of the 3-DAMHH by the experts satisfied the required standard in the field of Educational Technology. Percentage score of the rating for the validation of the 3-DAMHH by the experts satisfied the required standard in the field of Biology. This study concluded that the developed 3-DAMHH can be used to enhanced Biology students’ performance on the topic structure of the human heart. It was recommended among others that content specialists' and experts’ validation reports should be properly followed towards developing a standard instructional media.
This study examined the effect of Low-cost Technology on Secondary School students’ academic performance in Biology. Quasi-experimental research of post-test non-randomized control group design was adopted for this study. This design was adopted to compare the performance of students who were taught the concept of biology with low-cost technology and those taught without the low-cost technology. Two intact classes from two secondary schools were randomly sampled. The instruments used were Lesson Note (LN), Biology Performance Test (BPT) for data gathering, and Low-Cost Technology (3D Model of Plant and Animal Cells). BPT was subjected to pilot testing and a reliability coefficient of 0.87 was obtained using the Kuder Richardson KR-20. Two research questions and two research hypotheses were formulated for the study. Findings show that the 3D Model of Plant and Animal Cell significantly influences the understanding of the topic “Plant and Animal Cells” among students irrespective of their gender and institutional ownership. Secondary school teachers should make use of those low-cost technological resources available in their environment for the production of instructional materials.
This study investigates students' attitudes towards the use of Google Classroom for learning at the University of Ilorin, Nigeria. Descriptive survey research is used in this study. The population for this study consisted of all students at the University of Ilorin, Nigeria. The population of this study consisted of undergraduates in ten selected faculties at the University of Ilorin. Samples were taken using a multi-stage sampling technique. Use of stratified sampling technique to divide the population into strata based on faculty. Then, random sampling technique was used to select 30 respondents from each stratum. Specifically, 30 undergraduate students were selected from ten faculties, bringing the total number of respondents to 300 people. The research finding is that students have a positive attitude towards the use of Google Classroom at the University of Ilorin. Gender has no significant effect on student attitudes towards the use of Google Classroom at Ilorin University. The research course did not have a significant effect on respondents' attitudes towards the use of Google Classroom at the University of Ilorin. The study concludes that Google Classroom's diverse potential can be harnessed and harnessed to transform teaching and learning processes from traditional chalk-talk methods to virtual or blended learning, which is increasingly recognized as a global best practice in the university field. It is recommended that University lecturers be encouraged to use Google Classroom because of the many benefits it has for teaching and learning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
