The proficiency in Mathematics skills is fundamental to success in the STEM disciplines. In the US, beginning college students who are placed in remedial/developmental Mathematics courses frequently struggle to achieve academic success (Fay,2020). Therefore, Mathematics remediation in college has become an important concern, and providing Mathematics remediation is a prevalent way to help the students who may not be fully prepared for college-level courses. Programs vary however, and the effectiveness of a particular remedial Mathematics program must be empirically demonstrated. The purpose of this study was to apply the sharp regression discontinuity (RD) technique to determine the effectiveness of the Jack Leaps Summer (JLS) Mathematic remediation program in supporting improved Mathematics learning outcomes among newly admitted Mathematics students in the South Dakota State University. The researchers studied the newly admitted Fall 2019 cohort of Mathematics majors (n=423). The results indicated that students whose pretest score was lower than the cut-off point and who were assigned to the JLS program, experienced significantly higher scores on the post-test (Math 101 final score). Based on these results, there is evidence that the JLS program is effective in meeting its primary objective.

Abstract: The findings presented herein report the results of the qualitative portion of a sequential, convergent mixed methods study that focused on the effects of two instructional methods, Direct Instruction (DI) and Inquiry-based Learning (IBL), on pre-service teachers’ achievement and self-reported mathematics-related anxiety over the course of a semester. These qualitative findings are intended to add contextualization to the previously reported findings of the quasi-experimental phase of the investigation which found no statistically significant difference between groups in content mastery but found a statistically significant difference over the course of the semester in self-reported levels of mathematics-related anxiety between students who experienced the two different instructional methods. Implications are discussed.

The purpose of this study was to investigate the relationship between the nature of small group discussion tasks and learners’ talk during Physical Science lessons. The study was conducted during Physical Science lessons with three self-selected groups of Grade 11 learners from one school. A total of three lessons were followed. During the lessons, learners were given group tasks to complete, and their discussion was audio-recorded. The small group discussion tasks were coded using the revised Bloom’s taxonomy. The audio-recordings were transcribed and coded using Mercer’s three types of talk. The nature of tasks in the small group discussions was paired with the type of talk used as the group members were responding to the tasks and the frequency of these pairs was analysed. Analysis of the tasks vs. types of talk used indicated that learners predominately used cumulative talk to find solutions to understanding tasks. Exploratory talk was predominately used to find solutions to application tasks. The findings show that this relationship between the nature of small group discussion tasks and learners’ type of talk is statistically significant at p = 0.05 level. No disputational talk occurrences were observed. It is noted that the type of talk used to address each type of task is related to the cognitive skills demanded by the task, group composition and the embracing of the spirit of ubuntu by the group members.

The logistics and cost of running large class tutorials to improve learning for students in high enrolment courses raise questions about whether the associated effort and cost are worthwhile. The option to replace these class activities with online homework with its promise of built-in feedback is attractive. Using an activity theory lens and an experimental design, we compared the impact of class tutorials with online homework to support learning offered in face-to-face lectures on student performance. We found that there were no topics in the introductory organic chemistry syllabus in which students who had completed online homework instead of large class tutorials performed better. In contrast, for all topics except ‘Curved arrows in mechanisms’, the mean performance of students who had attended a large class tutorial was statistically significantly better than for those who completed online homework instead. This large quantitative study with a sample of 667 students demonstrated the advantage conferred by face-to-face tutorials with peer learning and personal feedback even in a large class setting with only three sessions per student. Our recommendation is that an online homework system in blended courses should not replace face-to-face tutorials for topics reliant on personalised instruction and feedback. We advocate for investing resources and effort to provide face-to-face problem-solving sessions in high-enrolment introductory organic chemistry courses to improve performance.

The present study explores the validity of inferences that may be drawn from the Trends in International Mathematics and Science Study (TIMSS) learner achievement data by measuring the South African curriculum–TIMSS alignment for the Grade 8 science assessments from 2007 to 2019. The Singapore curriculum–TIMSS alignment indices are a fair benchmark for comparison, as Singapore is the best-performing country in the TIMSS. The research questions that guide the present study included the calculation and comparison of the South African curriculum–TIMSS and Singapore curriculum–TIMSS alignment indices. The study analysed 585 South African curriculum items, 659 Singapore curriculum items and 1025 TIMSS assessment items from 2007 to 2019. The present study employed four raters and achieved an inter-rater reliability coefficient of 0.85. The South African curriculum–TIMSS analysis achieved an average content alignment index of 0.34, and an average cognitive alignment index of 0.54. As a benchmark, the Singapore curriculum–TIMSS analysis achieved an average content alignment index of 0.36 and an average cognitive alignment index of 0.74. The literature reviewed supports acceptable content and cognitive alignment indices of 0.67 and 0.65, respectively. The present study concludes that valid inferences from learner performance in the TIMSS may not be drawn for the case of South Africa, and even for Singapore valid inferences are based on cognitive alignment only. However, South Africa’s continued participation in the TIMSS is encouraged as the literature supports many benefits associated with the TIMSS non-achievement data.
