Abstract

Meaningful instruction takes place only with the appropriate use of instructional materials, especially in their real form. Inability to have access to mammalian internal organs is one of the challenges in teaching some concepts in Biology. Lack of practical experience in the teaching and learning of Biology that leads to poor mastery of important scientific skills and concepts could be among those factors responsible for students’ poor performance in Biology. Hence, the need to design and develop the Model of Human Excretory System (MHES) to teach Biology concepts in secondary schools. The study was a developmental research design, ADDIE instructional system design model was adopted in the production and evaluation of the model. The development involved four out of the five stages of the ADDIE model. The adapted phases include ADDE; these are Analysis, Design, Development, and Evaluation. Findings of this study revealed that: The model of the human excretory system was successfully developed using four (ADDE) out of the five stages of the ADDIE model as a guide and the cost of developing the model of the human excretory system was determined and found to be cheaper through the use of locally sourced materials.

Abstract

To establish the accuracy and usability of the instructional model, it must be verified by experts in the area of the subject content. The model of the human excretory system (MHES) has to be examined 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 MHES before it can be used to teach a Biology concept. Descriptive research of the survey type was adopted for this study. The sample for this study comprised three educational technology experts from the Department of Educational Technology and three Biology education experts from the Department of Science Education, University of Ilorin, Nigeria. Two instruments were developed for the study: Educational Technology Experts’ Rating Scale and Biology Education Experts’ Rating Scale. Descriptive statistics of the mean score and standard deviation were used to analyze the research questions. The findings of this study revealed the experts’ overall assessment of the effectiveness of the model for instruction was high, suitable, and found to be adequate. Based on the findings of this study, it is concluded that the developed MHES can be used to enhance Biology students’ academic performance on the topic human excretory system
