<p>This paper focuses on the construction of a hand drum by a Native American drum maker, and the construction of an anastomosis by a thoracic cardiovascular surgeon. Neither activity occurred with written instructions or illustrations. Each construction occurred through the ability to move mental images and procedures to their fingertips using their visuospatial reasoning (Owens, 2015). For the drum maker, learning was through mentorship, observation, and practice. Each of them, the drum maker and surgeon, developed rich spatial reasoning skills that are built on relationships. For the drum maker the relationships have to do with the geometry of the drum and it’s components just as the surgical geometry relationships exist in the operating room. For the drum maker tensions are felt with the fingertips, the same experience of the surgeon. Parallels are highlighted between these seemingly unrelated activities with a discussion of possible implications for Mathematics Education.</p><p><strong>Keywords</strong>: Ethnomathematics.

This review of the literature examines studies of the use of mental images by the blind in such cognitive tasks as verbal problem solving and spatial reasoning. It proposes that because mental images available to them are not adequate for certain cognitive tasks, the congenitally blind may rely on different modes of representation to compensate for their limited perception of and experience with the environment.

A complete Rasch multi-faceted analysis was performed on the draft Spatial Reasoning Assessment. While the psychometric report presents the complete analysis for the examination, this discussion proceeds step-by-step to understand the way in which the analysis proceeded, and the findings therein. The findings were that holistically, the instrument performed admirably. As a pretest, it is likely that students were not expected to demonstrate certain reasoning skills (e.g., GIS) as indeed they did not. The rating scale functions well to capture the examiner judgement. Overall, the instrument works together as a functional assessment, capturing the general construct of Spatial Reasoning.

As the end of the twentieth century approaches, we start to realize again the significance of proof in mathematics education. The NCTM's Curriculum and Evaluation Standards for School Mathematics (1989) cautions against the tendency to completely abandon proofs and focus only on the end results and formulas. In this article, we reemphasize the importance of proofs in teaching by sharing some of our experiences as students and teachers in Hungary, in addition to our experiences as graduate teaching assistants at an American university. We offer examples and ideas that might help educators develop students' mathematical reasoning skills.

This research was conducted to analyze the mathematical Inductive reasoning abilities of students’ mathematics education UNIPA. Research on inductive mathematical reasoning skills using qualitative methods using observation techniques, tests and interviews. The results showed that the mathematical inductive reasoning abilities of mathematics education students UNIPA were mostly in the moderate category. Students' inductive reasoning ability on each indicator is the ability to present mathematical statements in writing or drawings of 66.66%, the ability to submit suspicions by 26.66%, mathematical manipulation ability of 29.44%, ability to compile evidence, provide reasons or evidence for some solutions of 5.82%, finding patterns or traits of mathematical symptoms to generalize of 30.27%, examining validity of arguments 11.32% and drawing conclusions from statements of 5.27%.
