D. Elebute <p>Physical chemistry has been an aspect of chemistry which students find difficult at the secondary and tertiary levels of education. In the past, the effort of researchers has been focused on the research that will identify various causal factors which can be attributed to the performance of the learners in this aspect of chemistry. Also, very few experimental studies, has been carried out to improve students’ performance. In order to find the right bases for all research that will improve students’ achievement, there is a need to profile the misconceptions in the aspect of physical chemistry which is chemical equilibrium. The purpose of this study is to determine students’ misconceptions regarding the concepts of chemical equilibrium. To diagnose students' misconceptions in this area, a two-tier multiple-choice question on chemical equilibrium test was administered to 300 high school students in Ilesa Metropolis of Osun- state, Nigeria. Descriptive analysis was used in analyzing the data, students’ responses in a Chemical Equilibrium Misconception Test (CEMT) were categorized. The results revealed widespread misconceptions among students in the areas related to (1) equilibrium constant (2) heterogeneous Equilibrium (3) Approach to chemical equilibrium, (4) Application of Le-Chatelier Principle and (5) adding a catalyst.</p> 2020-12-21T00:00:00+00:00 Copyright (c) Students’ conceptual understanding of organic chemistry and classroom implications in the Rwandan perspectives: A literature review 2021-02-24T11:53:07+00:00 Aimable Sibomana Claude Karegeya John Sentongo <p>Chemistry subject continues to be considered as difficult to teach and learn. This leads to students’ low academic achievement, retention, and negative attitude towards the subject. Organic chemistry as one of the concepts on which technological advancement is constructed sometimes appears to be enormously complex to students. There are some persisting misconceptions about it although different innovative instructional strategies have been applied and this area is of main concern as the learning of students can be extremely hindered in case their misconceptions are not minimized and/or corrected. The review then is to equip educators with knowledge about organic chemistry concept and source of students ‘misconceptions; the misconceptions of students about organic chemistry; the ways of diagnosing students’ misconceptions and remedies of those misconceptions; some learning theories for the effective organic chemistry instruction and classroom implications. The paper is also useful to know more about the minimization of students’ misconceptions and leading them to the great academic achievement and interest towards the subject by employing cooperative learning models; thus, many other different innovative teaching strategies are recommended to apply in organic chemistry instruction</p> 2020-12-21T00:00:00+00:00 Copyright (c) Biology Instructional Resources Availability and Extent of their Utilization in Teaching Pre-Service Biology Teachers 2021-02-24T12:37:09+00:00 Josiane Mukagihana Florien Nsanganwimana Catherine Aurah <p>Education of pre-service science teachers necessitates inquiry and resource-based instruction to ensure the production of both hands-on and mind-on skilled science teachers. This becomes possible when a variety of instructional resources regularly support the teaching process. This study aimed to identify the types of available biology instructional resources and their extent of use in teaching pre-service biology teachers. The study used a descriptive survey research design and was conducted in three private Universities selected from those offering education in Rwanda. Eighty-two pre-service biology teachers and five biology lecturers participated in the study. Observational checklist of biology instructional resources and questionnaires aided the collection of data analyzed by frequency counts and percentages. The findings revealed that biology instructional resources like classroom chairs, chalkboards, laboratories, microscopes, centrifuge, slide projectors, biology textbooks were available while resources like a class whiteboard, classroom overhead projectors, electrophoresis unit, recorders, Polymerase chain reaction machines, among others, were absent. The findings also revealed low-level use of available biology instructional resources in teaching pre-service biology teachers. The implication is the likelihood of producing less competent future biology teachers. The provision of adequate biology instructional resources, as well as the monitoring of their use in teaching biology, was recommended</p> 2020-12-21T00:00:00+00:00 Copyright (c) 2021 Impact of gamification and experiential learning on achievement in mathematics among learners with hearing impairment in Lagos State, Nigeria 2021-02-22T12:44:58+00:00 Samuel Adeniyi Olaotan Kuku <p>There had been mixed observations about the ability and achievement of learners with hearing impairment. However, there are consensus that impactful teaching effort could aid in stimulating innovative approaches in teaching and learning of mathematics of learners particularly among learners with hearing impairment. This study seeks to appraise the impact of gamification and experiential learning on achievement in mathematics among learners with hearing impairment in Lagos State, Nigeria. The study population comprised learners with hearing impairment in Lagos State. Purposive and simple random sampling were used to select sample of 24 learners. The research design used was quasi-experimental pretest posttest traditional method &nbsp;group. Mathematics Knowledge Check (MKC) was used to collect data and the data collected were analyzed using mean, standard deviation, mean difference and analysis of covariance (ANCOVA). The hypotheses were tested at 0.05 level of significance. The study found out that achievement in Mathematics differs as a result of exposing learners with hearing impairment to gamification and experiential learning methods of instruction. Besides, the study observed that the two interventions benefit were of benefit to male and female learners with hearing impairment. The employment of gamification and experiential learning instructional strategy was recommended for mathematics lessons of learners with hearing impairment.</p> 2020-12-21T00:00:00+00:00 Copyright (c) An Overview of Learning Cycles in Science Inquiry-based Instruction 2021-02-23T12:12:11+00:00 Christian Nicol Emmanuel Gakuba Gonzague Habinshuti <p>While a plethora of researchers have acknowledged the importance of learning cycles as a model of instruction in a constructivist supported enquiry science education, the rising number of learning cycle models however raises compelling questions about validity, hence the need for a comprehensive overview and analysis of the comparative strengths and weaknesses of these models. This paper examined among the very many, four major learning cycles; 3E, 5E, 7E and 9E, on the scales of knowledge construction, to provide adequate information for decision making regarding their preference and use. While the 3E provides the very basic framework for expansion, it missed addressing the learners’ initial dialogic engagement with teachers as well as summative evaluation of learning. Critical analysis informed the conclusion that there are three main goals common to the learning cycles under review namely; the development of conceptual understanding, process skills and critical thinking. A well-planned and implemented 5E model generally meets the inquiry-based constructivist learning goals, although it is silent on transfer of knowledge outside of the classroom. This transfer of knowledge, provided for in the 7E, is the major meaningful difference between 5E and 7E. The three new phases introduced in the 9E, Echo, Emend and E-search, were assessed to be redundant. After a thorough needs assessment of the phases of the learning cycles under review, a six-phase learning cycle is proposed comprising Engage, Explore, Explain, Elaborate, Evaluate and Extend.</p> 2020-12-21T00:00:00+00:00 Copyright (c) Teachers’ perceptions towards the utilization of WhatsApp in supporting teaching and learning of chemistry during COVID-19 pandemic in Rwandan secondary schools 2021-02-22T13:12:48+00:00 Ezechiel Nsabayezu ezechielnsabayezu109@gmail.comrw Aloys Iyamuremye Jean de Dieu Kwitonda Jean de Dieu Kwitonda Agnes Mbonyiryivuze <p>This paper reports the results about teachers’ perceptions towards the utilization of WhatsApp in supporting teaching and learning of chemistry during the COVID-19 pandemic in Rwandan selected secondary schools. The collected data by using a survey questionnaire were from 18 chemistry teachers in Nyarugenge and Kicukiro Districts. The findings illustrated that WhatsApp is effective for teaching chemistry and supporting students learning. This application promotes students’ motivation, engagement, collaboration, interaction, participation, and ubiquitous learning. Despite the facilitation of collaboration between teachers and their students while using WhatsApp, the internet connection related problems including its cost and availability were among the hindering factors for effective collaboration for both students and teachers. The lack of smartphones and computers for some students, teachers, parents, or guardians was among the highlighted limitations for the participation of some students. The limited students’ management and their distraction were also highlighted by some teachers. The provision of computers, smartphones, and enough internet connection for all teachers, parents, or guardians were among the proposed potential solutions. To deal with students’ management and distractions while learning via WhatsApp, there should be the follow-up and guidance provided by teachers, guardians, or parents. Chemistry teachers and students are recommended to use WhatsApp as a supporting learning tool due to its added value of providing ubiquitous learning. Parents, boards in charge of education, and other educational stakeholders should integrate WhatsApp in teaching and learning to complement classroom learning.</p> 2020-12-21T00:00:00+00:00 Copyright (c) Effectiveness of Practical Work in Physics on Academic Performance among Learners at the selected secondary school in Rwanda 2021-02-23T07:59:25+00:00 Jean Twahirwa Etienne Twizeyimana <p>The current study investigates the effectiveness of practical work in physics on academic performance among learners of a secondary school in Rwanda. The study employs a quasi-experimental research design specifically pretest-posttest control group design (control group and experimental group). Two groups of learners of senior one at Groupe Scholaire Rugoma were treated differently through an expository and practice-based approach respectively. Physics achievement test prepared to evaluate the effect of practical work indicated that learners in the experimental group outperformed those of the control group treated by the expository teaching method. Various factors that may advance or hinder the implementation of practical work were identified and views from science teachers were collected. Most of the respondents strongly agreed that those factors have a significant impact on the implementation of practical work which in turn influence learners’ overall academic performance during Physics Achievement Test (PAT). A significant difference was observed from the statistical analysis performed by using SPSS version 21.0. (Pretest and posttest among learners in the experimental group; t = 27.243; 32.743; MD = 8.4239; 13.12500 respectively whereas the pretest and posttest among learners are as follow, t = 28.442; 32.627; MD = 9.82500; 2.38005 respectively and for all performance evaluation hypotheses were tested at .05 level of significance. Based on the observed results, it was found that practical work was more effective in improving learners’ performance in Physics. It was therefore concluded that practical work continues to be a promising approach in teaching sciences, particularly teaching Physics in secondary schools.</p> 2020-12-21T00:00:00+00:00 Copyright (c) Effect of technical university students’ language proficiency on their academic performance measured by their final cumulative grade point average 2021-05-29T08:57:47+00:00 Maame-Afua Nkrumah <p>The importance of language in Technical and Vocational Education and Training (TVET) cannot be over-emphasized. Although TVET focuses on skill acquisition, the desired skills cannot be acquired, if students are not proficient in, and cannot fully comprehend, the language of instruction during lectures and examinations. It was for this reason that, the current study looked at the effect of students’ language proficiency on their academic success as measured by their final cumulative grade point average (CGPA) using multilevel modelling techniques. Gender differences in the students’ academic success were also explored. The study was based on a data-set of 17,714 students (5,882 female and 11,832 males) from one Ghanaian Technical University in Ghana. It was observed that communication skills course grades, the proxy measure of their language proficiency, accounted for 15% of the total variance in the students’ CGPA. This confirms the important role language plays in TVET. The study findings are expected to assist TVET stakeholders in systemically re-orienting the minds of TVET students towards proficiency in the language of instruction.</p> 2021-05-29T00:00:00+00:00 Copyright (c)
