  The study investigated pupils’ achievement in rational numbers, using constructivist models and traditional approach of instruction as connecting points between pupils’ prior knowledge of whole numbers concept and the new concept. Pre-test post-test non-equivalent control group quasi-experimental research design was adopted. A research question guided the study and was answered using descriptive statistics; and a formulated corresponding null hypothesis was tested at 0.05 level of significance, using analysis of covariance (ANCOVA). A sample of 103 pupils was used for the study. A test instrument titled Rational Numbers Achievement Test (RNAT) was developed, validated and used to generate data. The instrument had 0.74 reliability index of internal consistency through the use of Kuder Richardson formula 21. The results showed that different types of representation are central to conceptual understanding, and are able to resolve pupils’ difficulties and misconceptions about rational numbers. Based on these findings, it was recommended that constructivist models of instruction should be part of the main instructional approaches for the teaching-learning of mathematics at the Basic Levels of the Nigerian school system.

<p style="text-align: justify;">The performance in biology at the secondary level has not been as good as expected. This has been a matter of concern. Thus, there has been a continuous focus on exploring newer innovative learner-centered and friendly instructional strategies to enhance understanding and retention in biology. This study, therefore, determined the effects of Concept Mapping (CM) and Cooperative Mastery Learning (CML) on fostering retention in photosynthesis among secondary schools in Nyamagabe district, Rwanda. A pre-test and post-test non-equivalent control group quasi-experimental design was used. Data were obtained from 151 students taught with CM, 144 students taught with CML, and 154 students taught with Conventional Teaching Methods (CTM). The Photosynthesis Retention Test (KR-21= 0.82) was used for data collection. The data were mainly analyze d using mean and Analysis of Covariance (ANCOVA). The results showed that the CM and CML treatment groups outperformed the CTM group in retention in photosynthesis. There was a statistically significant difference in favor of the CM between the two experimental groups. The male and female students taught using CM retained equally in photosynthesis while gender difference was revealed in the mean retention scores of the students exposed to the CML, with females retained significantly higher than males. The study concluded that the CM and CML strategies were more effective than CTM. It was suggested, among other things, that teachers should be encouraged to apply CM and CML strategies when teaching biology.</p>

The purpose of this study was to explore the effectiveness of GeoGebra assisted instruction on students’ achievement in drawing graphs of linear functions and interpretation of the representations of linear functions. These aspects of linear functions tend to pose a challenge to many students. The non-equivalent control group pre-test-post-test quasi-experimental research design was used in the study. The sample was 94 Grade 9 students from three secondary schools in a province in South Africa. Two schools formed the control groups and one school was the experimental group. Data were collected using achievement tests. The tests results were analysed using inferential statistics (Kruskal-Wallis and Mann-Whitney U comparison tests) at 0.05 level of significance. Statistically significant differences were found between the groups with respect to drawing and interpretation of linear functions graphs with the experimental group obtaining the highest mean scores. The findings suggest that GeoGebra assisted instruction might be a way of enhancing students’ ability to draw the graphs of linear functions and analyse and interpret the representations of linear functions.
