A survey of pre/post-test data using the Halloun–Hestenes Mechanics Diagnostic test or more recent Force Concept Inventory is reported for 62 introductory physics courses enrolling a total number of students N=6542. A consistent analysis over diverse student populations in high schools, colleges, and universities is obtained if a rough measure of the average effectiveness of a course in promoting conceptual understanding is taken to be the average normalized gain 〈g〉. The latter is defined as the ratio of the actual average gain (%〈post〉−%〈pre〉) to the maximum possible average gain (100−%〈pre〉). Fourteen “traditional” (T) courses (N=2084) which made little or no use of interactive-engagement (IE) methods achieved an average gain 〈g〉T-ave=0.23±0.04 (std dev). In sharp contrast, 48 courses (N=4458) which made substantial use of IE methods achieved an average gain 〈g〉IE-ave=0.48±0.14 (std dev), almost two standard deviations of 〈g〉IE-ave above that of the traditional courses. Results for 30 (N=3259) of the above 62 courses on the problem-solving Mechanics Baseline test of Hestenes–Wells imply that IE strategies enhance problem-solving ability. The conceptual and problem-solving test results strongly suggest that the classroom use of IE methods can increase mechanics-course effectiveness well beyond that obtained in traditional practice.

Building on and extending existing research, this article proposes a 4-phase model of interest development. The model describes 4 phases in the development and deepening of learner interest: triggered situational interest, maintained situational interest, emerging (less-developed) individual interest, and well-developed individual interest. Affective as well as cognitive factors are considered. Educational implications of the proposed model are identified.

Learning how to use a new software program can be a difficult and demanding task, especially for novices. There are several types of support for users exploring a software package. Animated demonstrations show how experts use an application, and training wheels interfaces offer a secure environment for exploration. To support different types of learners, external help should be adapted according to learner characteristics. The study presented in this article investigates effects of different support types in combination with the computer self-efficacy of learners. Young students (8th graders) were supported with text manuals, animated demonstrations, or animated demonstrations combined with a training wheels interface. In this context, they had to solve problems in physics and mathematics with a spreadsheet program. Results showed that animated demonstrations outperformed text manuals in many cases. Training wheels interfaces seemed to have disadvantages compared to unmodified user interfaces. In addition, motivational aspects have been investigated. Subjects with high computer self-efficacy scores were more motivated than their counterparts. Statistics (analysis of variance) revealed no interaction effects between the treatment and computer self-efficacy.

The development of scientific process skills is central to laboratory work in biology. A search for the laboratory interaction pattern that is most potent in the development of these skills is described. 720 secondary class three biology students were involved in a pre-test, treatment, post-test experiment in which competitive interaction was found to be superior to cooperative and individualistic interaction patterns in promoting the development of process/laboratory skills.

<p>This research reports on the design aspect of a bigger project which sought to design and implement information and communication technology (ICT)-based interventions for the purpose of developing pre-service teachers’ ICT competency for teaching physics in an interactive manner using a three-stage (design stage, implementation and evaluation stage, and documentation and reflection stage) design-based research approach. Using literature as a lens, this research examines the interventions that we designed in the first stage of the project with the intent to determine its features that promote interactive teaching and fit the Ghanaian senior high school physics classroom context. Findings show that the intervention with inherent features comprising of: a readily available, sustainable, context- and content-specific ICT teaching and learning environment; an ICT-oriented knowledge base for teachers’ uptake of ICT; an underlining framework for defining interactive and learner-centred teaching approach with ICT; ICT-driven interactive lesson objectives; an inquiry-driven, activity- and ICT-based learning material; and a collaborative classroom arrangement is appropriate and sensitive to the needs of the Ghanaian physics classroom context and, hence, possess the potential for promoting interactive teaching. The features of the interventions, as situated in the specific context of the research and implications of the findings are discussed.<strong></strong></p><p><strong> </strong></p>

Many students have problems when it comes to describing the shapes of displacement, velocity and acceleration-time graphs (x, v, a-t graphs), conversion of graphs from one form into another, and calculating and getting the meaning of slopes and areas under kinematics graphs. They often describe shapes of graphs as pictures and give interpretation without taking into cognizance of the type of graph being considered. In this study, 37 first year university physics students (Group One: 17 students and Group Two: 20 students) at the University of Education in Winneba (Ghana) in two consecutive years, were introduced to the use of microcomputer based laboratory (MBL) tools; simulations and graph samples to practice and describe the shapes of kinematics graphs; conversion of graphs from one form to the other; calculation of slopes and areas under kinematics graphs, and their meanings, all in an interactive engagement teaching. Students were made to answer the "Test of Understanding Graphs in Kinematics" (TUG-K) before and after the introduction of the use of MBL tools, simulations and graph samples. Students' scores were compiled and converted to mean proportion scores and average normalized gain 〈 g 〉, under the four concepts "Area under the graph (meaning and calculation); Slope (meaning and calculation); Graph description; and Graph transformation". The results indicate that the first year university students in the two groups all did better in describing the shapes of kinematics graphs, transforming kinematics graphs, calculating and getting the meaning of slopes and areas under kinematics graphs when they were tested with the same instrument after instruction in kinematics. This goes to show that MBL tools, simulations and graph samples when used in an interactive engagement manner can improve the teaching and learning of kinematics graphs in physics.

In this research, the impact of peer tutoring and group tutoring led to team learning approaches on the attitude of the students towards and achievement in biology. The thesis had been motivated by four research questions and six null hypotheses. The research had used a quasi-experimental method. In particular, the design of the un-equivalent control group. The sample size was 182 SS 1 students from the four sampled government senior high schools in Port-Harcourt metropolis, River State, Nigeria in four intact classrooms. Two of the classes were exposed to peer tutoring while the remaining two were exposed to peer-led team learning strategies. Biology Attitudinal Scale (BAS), and Biology Achievement Test (BAT) were data collection instruments. BAS construct validity was developed using factor analysis, while BAT material validity was calculated using the specification table. Reliability for BAS and BAT was obtained using formula 20 (K-R 20) from Cronbach Alpha and Kudar-Richardson. Mean and the standard deviation was used to answer the study questions while Covariance analysis (ANCOVA) was used to evaluate the hypotheses at 0.05 significance point. The findings showed that peer-led team learning approach is better than peer tutoring in enhancing the attitude and achievement of the students in biology. The implications of the findings were highlighted and recommendations made.

Teacher-dominated approach is still the most adopted teaching strategy in Ghanaian high schools despite the Government of Ghana’s initiatives to support technology-oriented, learner-centred and interactive teaching practices. This study examined the effectiveness of simulation-based lessons in improving the teaching of high school physics by adapting the five dimensions for meaningful learning with information and communication technology model by Howland, Jonassen and Marra (2012) as a theoretical lens. Using an explanatory case study design, eight pre-service physics teachers from the University of Cape Coast, Ghana were engaged to develop and design simulation-based physics lessons in design teams and enact these lessons among themselves in microteaching sessions. Results showed that the simulation-based lessons were effective in that the pre-service teachers’ teaching practices improved to be learner-centred and interactive. The results also suggested that although a combination of all the dimensions of meaningful learning was key to the effectiveness observed with each of the simulation-based lessons, the Cooperative dimension was found to possess a unique potential for sustaining the other dimensions in order to facilitate improvements in the teaching of physics with simulations. Keywords: high school physics, ICT, interactive teaching, pre-service teachers, simulation-based lessons.

At Atebubu College of Education, the study attempted to determine the impacts of peer tutoring on gender and senior High school background courses of pre-service teachers in physics. To achieve the purpose of the study an action research design was used and a total number of 140 (78 males and 62 females) who are offering primary Education program were purposively selected. The major research tools were accomplishment tests, which were used to collect quantitative data from pre-service teachers. Using the independent sample t-test and one-way ANOVA to analyse the quantitative data. It was found that the male students’ performance in Physics (M = 8.81, SD = 0.927) does not significantly differ from that of the female students’ (M = 8.65, SD = 0.925) as a result of the peer tutoring method adopted for the study. The results of the one-way ANOVA show that there are no differences in the mean score of the pre-service teachers’ performance in Physics and their senior High School course background. It is therefore recommended among other things that the principals and head of science departments of Colleges of Education in Ghana should organise workshops, seminars and in-service training on how to utilize peer tutoring method effectively in teaching scientific concepts to pre-service teachers they training.

The study sought to establish differences in the effect of cooperative learning strategy with and without the instructional manual on the Senior High School students’ performance in Mechanics concepts in Physics in the Berekum Municipality, Ghana. The research design employed in this study was the experimental using the pretest and posttest equivalent control group design. A sample of 93 SHS 2 students, drawn from two intact classes was used. An instrument known as Mechanics Concepts Test (MCT) was employed in data gathering. Mean score, standard deviation; t-test, mean gain and effect size analysis were used to answer the research questions, while the independent sample t-test was used to test a hypothesis. The results revealed that students taught using the cooperative learning strategy with the instructional manual performed significantly better in the Mechanics Concepts Test (MCT) than those taught using the cooperative learning strategy only. Therefore, it is recommended that physics teachers should use the cooperative learning strategy along with the instructional manual in order to enhance the performance of students in secondary schools.

Purpose of the study: The paper examines the use of Physics Education Technology (PhET) simulations to enhance the academic performance of third-year science students at Kumasi Wesley Girls' High School. Methodology: The research used teacher-made tests, questionnaires, and informal observations to collect data. Ninety candidates (90 students) were selected from the third-year science population using a cluster sampling. The questionnaire, pre-evaluation, and post-evaluation tests on vectors were analyzed using descriptive statistics. Main Findings: The study found that PhET-based teaching significantly improved the performance of third-year science students in vector resolution, with a paired mean difference of 6.30 compared to pre-treatment tests. The questionnaire analysis of 90 students revealed that 85.6% initially found vector applications difficult, and 80% felt the teaching methods were unvaried and boring. After the PhET lab simulation intervention, 89% of students were enthusiastic about using simulations in future activities, and 78% reported an improved understanding of resultant vectors. The study indicates that PhET simulations significantly enhance student engagement and comprehension compared to traditional lecture teaching methods. Novelty/Originality of this study: The study explores using Physics Education Technology (PhET) simulations in Ghanaian high school Kumasi Wesley Girls' High School to improve vector resolution learning. The interactive approach demystifies complex concepts, and the study quantifies its impact on students' academic performance. It also provides insights into students' attitudes towards physics education
