The study investigated the effects of Solve-Reflect-Pose Strategy (SRP) on pre-service mathematics teachers’ algebraic knowledge for teaching in Nigeria. A pre-test-post-test quasi experimental design was employed. Intact classes were used and in all, 182 pre-service mathematics teachers’ participated in the study (92 in the experimental group taught with the SRP and 90 in the control group taught using the Modified Conventional Method (MCM). One research instrument manipulated at three levels namely: Conceptual Knowledge Test (CKT), Procedural Knowledge Test (PKT) and Flexible Procedural Knowledge Test (FPKT), was used for the quantitative data and interview protocol for qualitative data. The two research questions formulated were analysed using descriptive statistics while independent sample t-test was used to analyse the two hypotheses. Results showed that there were statistically significant differences in the mean post-test achievement scores on conceptual knowledge test, procedural knowledge test and flexible procedural knowledge test between pre-service teachers exposed to the SRP and those exposed to the MCM, all in favour of the SRP group. Based on the results, SRP should be adopted as an instructional strategy and efforts should be made to integrate the philosophy of SRP into the pre-service teachers’ curriculum at the teacher-preparation institutions.

<p>This study investigated the effects of activity-based instructional strategy on senior secondary schools students’ retention in circle geometry. The study employed a quasi-experimental design of the type pre-test, post-test groups design. The sample for the study comprised of 162 senior secondary 2 students drawn from two randomly selected co-educational schools in Federal Capital Territory, Nigeria. The research instrument was Mathematics Retention Test (MRT) containing items adapted from standardized WAEC questions. The test –retest method was employed for the reliability of the test instrument. The Pearson Product Moment Correlation Coefficient (r)=0.86 was obtained. Data collected were analyzed using t-test. The finding of this study revealed that there was a significant difference in the retention of students taught circle geometry using activity-based instructional strategy (ABIS) and the students taught circle geometry using conventional methods in favour of the students taught using ABIS. The study also indicated that there was no significant difference between the retention of male and female students in the experimental group who were taught circle geometry using ABIS. It was therefore recommended that mathematics teachers should use strategies that will encourage the active participation of students in mathematics classes such as ABIS which in turn would enhance retention. Also, governments at all levels should organize trainings and/or workshops for mathematics teachers on the use of ABIS in teaching mathematics.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0873/a.php" alt="Hit counter" /></p>

Integrating the properties of computer algebra systems and dynamic geometry environments, Geogebra became an effective and powerful tool for teaching and learning mathematics. One of the reasons that teachers use Geogebra in mathematics classrooms is to make students learn mathematics meaningfully and conceptually. From this perspective, the purpose of this study was to investigate whether instruction with Geogebra has effect on students’ achievements regarding their conceptual and procedural knowledge on the applications of derivative subject. This study adopted the quantitative approach with pre-test post-test control group true experimental design. The participants were composed of two calculus classrooms involving 31 and 24 students, respectively. The experimental group with 31 students received instruction with Geogebra while the control group received traditional instruction in learning the applications of derivative. Independent samples t-test was used in the analysis of the data gathered from students’ responses to Applications of Derivative Test which was subjected to them before and after teaching processes. The findings indicated that instruction with Geogebra had positive effect on students’ scores regarding conceptual knowledge and their overall scores. On the other hand, there was no significant difference between experimental and control group students’ scores regarding procedural knowledge. It could be concluded that students in both groups were focused on procedural knowledge to be successful in learning calculus subjects including applications of derivative in both groups. On the other hand, instruction with Geogebra supported students’ learning these subjects meaningfully and conceptually.

A preliminary study of students of a psychology faculty, revealed the fact that there are some students with low life satisfaction and negative affect during their college life. Low subjective well-being (SWB) was associated with decreased productivity and cognitive flexibility, which are important elements for studying. Previous researchers found a significant correlation between gratitude and SWB. The aim of this study is to enhance student SWB through an intervention of gratitude letter. We use two stages in this study: first a descriptive method (N = 282) to have an accurate description of the level of their SWB. Then, we select 60 students with the lowest SWB to participate in the next stage, a quasi-experimental method with multiple group design, consisting of two experimental group and one control group. Measurements were conducted with modified SLS, SPANE, and GQ6. Data a-nalysis revealed significant differences in gratitude and positive affect level that are differrent in each group. Significant improvement in gratitude and subjective well-being based on the pre-test, post-test 1, post-test 2 were only found in the group that writes and expresses the gratitude letter.
