Data on students' mathematical reasoning test scores: A quasi-experiment.

ABSTRACT: The data presented here were collected from 301 grade 11 students selected from six public secondary schools within one district. These students participated in a quasi-experimental study whose aim was to investigate the effects of the Student-Teams Achievement Division (STAD) on students' mathematical reasoning. Six intact classes from the participating schools were selected using a cluster random sampling method, three of which were randomly assigned to the control group while the other three were randomly assigned to the experimental group. Respondents' demographic information (identity, gender, school type, and age) are presented alongside their raw scores on pretest and posttest measures. The mathematical reasoning test (MRT) items presented to students aimed at assessing their conjecturing, justifying and mathematizing abilities. Student scores from each of these three mathematical reasoning dimensions were aggregated to form a total score for both the pretest and posttest measures. These data can provide some insights into the extent to which different learning conditions can support the development of reasoning among the learners of school mathematics. The MRT items presented in the supplementary data files can also act as a basis for the formulation of new tasks aimed at assessing students' mathematical reasoning skills.

Project description:BACKGROUND:Over-testing of patients is a significant problem in clinical medicine that can be tackled by education. Clinical reasoning learning (CRL) is a potentially relevant method for teaching test ordering and interpretation. The feasibility might be improved by using an interactive whiteboard (IWB) during the CRL sessions to enhance student perceptions and behaviours around diagnostic tests. Overall, IWB/CRL could improve their skills. METHODS:Third-year undergraduate medical students enrolled in a vertically integrated curriculum were randomized into two groups before clinical placement in either a respiratory disease or respiratory physiology unit: IWB-based CRL plus clinical mentoring (IWB/CRL?+?CM: n?=?40) or clinical mentoring only (CM-only: n?=?40). Feasibility and learning outcomes were assessed. In addition, feedback via questionnaire of the IWB students and their classmates (n?=?233) was compared. RESULTS:Analyses of the IWB/CRL sessions (n?=?40, 27 paperboards) revealed that they met validated learning objectives. Students perceived IWB as useful and easy to use. After the IWB/CRL?+?CM sessions, students mentioned more hypothesis-based indications in a test ordering file (p?<? 0.001) and looked for more nonclinical signs directly on raw data tests (p?<? 0.01) compared with students in the CM-only group. Last, among students who attended pre- and post-assessments (n?=?23), the number of diagnostic tests ordered did not change in the IWB/CRL?+?CM group (+?7%; p?=?N.S), whereas it increased among CM-only students (+?30%; p?<? 0.001). Test interpretability increased significantly in the IWB/CRL?+?CM group (from 4.7 to 37.2%; p?<? 0.01) but not significantly in the CM-only group (from 2.4 to 9.8%; p?=?0.36). CONCLUSIONS:Integrating IWB into CRL sessions is feasible to teach test ordering and interpretation to undergraduate students. Moreover, student feedback and prospective assessment suggested a positive impact of IWB/CRL sessions on students' learning.
