The goal of this paper is to compare freshman engineering students' spatial abilities (Spatial Intelligence) at two universities: Sharif University in Tehran and Debrecen University of Hungary, focusing on both their final mathematical exam performance and their gender so as to ascertain whether the students differ significantly in terms of their spatial abilities and/or their problem solving methods. The tests used to measure spatial intelligence performance and mental rotation was the Purdue Spatial Visualization Test (PSVT Branoff). The test results have been statistically evaluated and conclusions formulated. The results show that there was no significant difference between Iranian and Hungarian freshman engineering students in the performance of mental rotation tasks. However, a general gender difference in spatial ability performance was evident among the Hungarian students but not among the Iranians. The results also shed light on spatial rotation problem-solving methods that appear to be largely specific to females.

Objectives: The aim of this study was to examine the relationship between the spatial abilities of medical school students and their learning in anatomy. Methods: The spatial abilities of the 120 students (74 females, 46 males) were examined using Mental Rotation Test (MRT). The relationship between the mental rotation scores and the mean scores of their practical and theoretical anatomy examinations was determined in terms of gender. Results: The study revealed that mental rotation skills of female participants were lower than males; however, there was no significant difference in their exam (theoretical and practical anatomy examinations) scores in terms of gender. The spatial ability of the students had a low level significant effect on their anatomy scores, regarding practical applications. Conclusion: The results of the study revealed a significant relationship between students’ spatial ability and their success in practical anatomy examinations. This suggests that improving spatial ability skills may have a significant contribution to practical anatomy learning and may be considered as a part of anatomy education.

Task Interpretation

Understanding problems or tasks is a critical step in any problem-solving activity and the heart of self-regulated learning. When encountering a problem, students draw upon information available in the environment, along with knowledge, concepts, and perceptions derived from prior learning experiences, to interpret the demands of the task. Interpretation of tasks is, therefore, a key determinant of the goals set while learning, strategies selected to achieve those goals, and the criteria used to self-assess and evaluate outcomes. The purpose of this study is to better understand engineering students’ self-regulation in task interpretation processes while engaged in problem solving in an introductory engineering thermodynamics course. Two research questions guided the study: (1) What are the gaps, if any, between the instructor’s and students’ interpretation (explicit and implicit task features) of a problem-solving task?; and (2) How do students’ task interpretation (explicit and implicit) change after engaging in self-evaluation of their problem-solving processes? One hundred twelve (112) second year engineering undergraduates voluntarily participated in the study. Analysis of the data collected revealed a significant difference between the instructor’s and students’ task interpretation of the assigned problems. Furthermore, the analysis showed that students’ had a higher ability to identify the explicit parts of problem tasks than implicit ones. Students were able to grasp 63 to 77 percent and 39 to 49 percent, respectively, of the explicit and implicit information that was presented to them while engaged in problem-solving activities.

Abstract The nature of 3D ability is deeply considered, but little is known about students’ learning and understandings of technology and about the meaning to become more technologically capable. We considered the spatial intelligence of first-grade engineering students, how much that improved to the effect of 18 times 45 minutes course of computer-aided 3D modeling. We consider the success of our 3D course in spatial intelligence. According to the result of the tests, one-third of the engineer candidates has good spatial intelligence. We introduce some useful problems in 3D education; the presented problems help the students in learning how to solve technology problems, and how to design objects. We offer the intellectual pleasure of problem solving through 3D problems. Our CAD course excellently improves the spatial skills of the middle third of the students. Computer-aided 3D modeling also bridges the gap for students with worse spatial ability. Dealing with students in a more differentiated way about CAD modeling would be advisable.

Recent study shows an increasing interest towards the implementation of augmented reality in teaching and learning. Majority of the studies in this area focuses on how this technology could impact students’ performance and various skills including visualization skills. Hence, the purpose of this study was to examine the differences in students’ visualization skills after utilizing Mobile Augmented Reality (MAR) and conventional learning in orthographic projection classroom. This study involved 60 students and was conducted in Universiti Teknologi Malaysia: 30 students in experimental group used MAR; 30 students in control group used conventional learning. In this study, mental rotation skills were measured using Purdue Spatial Visualization Test of Rotation (PSVT:R) due to its importance to ensure students understanding in orthographic projection. Results from this study showed a significant difference between students in both group where students in experimental group displayed a significantly higher level of visualization skills in terms of mental rotation skills compared to students in control group. At the end of their study, respondents were given a set of questionnaires to obtain their feedback on the use of MAR. Based on students’ positive feedback on MAR, the result proved that it can be an effective spatial visualization tool. MAR is also practical to be used in classrooms since it has low production cost.

Purpose The purpose of this paper is to identify the effects of algorithm teaching on the problem-solving skills of deaf-hard hearing students. Design/methodology/approach In this research, a pre-test and post-test problem-solving scale was applied to the single group (16 deaf-hard hearing students at a secondary school level) that had received algorithm education. Pre-test and post-test results were compared in order to see whether there was a significant difference among students in terms of their problem-solving attitudes. Students’ levels of performing the applications were examined through observation forms and their opinions about algorithm teaching were received. Findings As a result of the research, it was determined that implemented algorithm teaching had a significant effect on improving the problem-solving skills of the students. Originality/value Scratch training can be administered as either a compulsory or an optional course for hearing students as the Scratch programme offers the opportunity of teaching algorithmic reasoning with games, making the courses entertaining and giving students the chance to create their own designs which helps to improve their creative problem-solving skills and their motivation accordingly. Scratch teaching can be beneficial in developing students’ problem-solving behaviours and creativity.

Males are generally overrepresented in higher education engineering. However, the magnitude of this variance differs between countries and engineering fields. Evidence associated with the field-specific ability beliefs hypothesis suggests that perceptions of intelligence held by actors within engineering affects the engagement of underrepresented groups. This study examined perceptions of an intelligent engineer held by undergraduate and postgraduate engineering students in Ireland and Sweden, countries selected based on their levels of female representation in engineering education. It was hypothesised that there would be a significant difference in perceptions between countries. A survey methodology was employed in which a random sample of Irish and Swedish university students completed two surveys. The first asked respondents to list characteristics of an intelligent engineer, and the second asked for ratings of importance for each unique characteristic. The results indicate that an intelligent engineer was perceived to be described by seven factors; practical problem solving, conscientiousness, drive, discipline knowledge, reasoning, negative attributes, and inquisitiveness when the data was analysed collectively, but only the five factors of practical problem solving, conscientiousness, drive, discipline knowledge and negative attributes were theoretically interpretable when the data from each country was analysed independently. A gender × country interaction effect was observed for each of these five factors. The results suggest that the factors which denote intelligence in engineering between Irish and Swedish males and females are similar, but differences exist in terms of how important these factors are in terms group level definitions. Future work should consider the self-concepts held by underrepresented groups with respect to engineering relative to the factors observed in this study.

AbstractSpatial ability contributes to performance in science, technology, engineering and mathematics (STEM). Spatial skills and creativity are required for engineering studies. Low spatial abilities can lead to the dropout of students’ university studies. In this study the Spatial Ability Extra Tasks (SAET) was developed to evaluate engineering students’ complex spatial abilities. A total of 93 first-year engineering students from University of Debrecen Faculty of Engineering and Sharif University of Technology in Tehran participated, with regard to final mathematical exam and their gender, participated in the study. SAET measures parts of spatial abilities: mental cutting and mental rotation and creativity. Analysis of the findings suggested that SAET is valid and reliable. The separate tests results have been statistically evaluated and conclusions were formulated. We used Structural Equation Modeling analysis. We separate two types of tasks by SAET which are Polyhedron part and Curved Surface part. According to obtained data, accomplished the results: students of University of Debrecen are more successful at Curved Surfaces. In addition students of Sharif University are more successful at Polyhedrons. The square cross section was found by most student in both countries in Polyhedrons. It is remarkable that first-year engineering students of Tehran are more successful at Polyhedrons by pentagon, hexagon and parallelogram solution; and students of Debrecen are more successful by square and rectangle solution. Students of Debrecen are more successful at Curved Surfaces to find circle solution of cylinder, cone and sphere; students of Tehran are more successful by finding parabola solution of cone.

Abstract Visual-spatial abilities are relevant for performing diverse everyday tasks as well as being successful in multiple fields. This work provides empirical evidence supporting the claim that studying a computer graphics course, as commonly offered in computer science or engineering programs, can help develop stronger visual-spatial abilities. This benefit was estimated with the assessment of students’ performances in a standardized test of visual-spatial abilities. This empirical pre-test/post-test study ran for three consecutive semesters and involved six computer graphics groups where students were evaluated with the Purdue Spatial Visualization Test to measure whether the full-semester working on contents heavily related to 2D/3D geometric transformations had a positive effect on students’ visual-spatial intelligence. Results show a statistically significant increase in the average score in the test, which in turn suggests that these cognitive abilities could be reinforced or trained through the normal course workload. Additional findings in this study suggest that a retest gaining factor is present just by taking the test twice, and that there is a weak correlation between students’ level of visual-spatial abilities at the beginning of the course and the final grades obtained at the end of the semester.
