Evaluation of Static and Dynamic Visualization Training Approaches for Users with Different Spatial Abilities

Photorealistic 3D models (PR3DM) have great potential to supplement anatomy education; however, there is evidence that realism can increase cognitive load and negatively impact anatomy learning, particularly in students with decreased spatial ability. These differing viewpoints have resulted in difficulty in incorporating PR3DM when designing anatomy courses. To determine the effects of spatial ability on anatomy learning and reported intrinsic cognitive load using a drawing assessment, and of PR3DM versus an Artistic colour-coded 3D model (A3DM) on extraneous cognitive load and learning performance. First-year medical students participated in a cross-sectional (Study 1) and a double-blind randomised control trial (Study 2). Pre-tests analysed participants' knowledge of anatomy of the heart (Study 1, N = 50) and liver (Study 2, N = 46). In Study 1, subjects were first divided equally using a mental rotations test (MRT) into low and high spatial ability groups. Participants memorised a 2D-labeled heart valve diagram and sketched it rotated 180°, before self-reporting their intrinsic cognitive load (ICL). For Study 2, participants studied a liver PR3DM or its corresponding A3DM with texture-homogenisation, followed by a liver anatomy post-test, and reported extraneous cognitive load (ECL). All participants reported no prior anatomy experience. Participants with low spatial ability (N = 25) had significantly lower heart drawing scores (p = 0.001) than those with high spatial ability (N = 25), despite no significant differences in reported ICL (p = 0.110). Males had significantly higher MRT scores than females (p = 0.011). Participants who studied the liver A3DM (N = 22) had significantly higher post-test scores than those who studied the liver PR3DM (N = 24) (p = 0.042), despite no significant differences in reported ECL (p = 0.720). This investigation demonstrated that increased spatial ability and colour-coding of 3D models are associated with improved anatomy performance without significant increase in cognitive load. The findings are important and provide useful insight into the influence of spatial ability and photorealistic and artistic 3D models on anatomy education, and their applicability to instructional and assessment design in anatomy.

Previous studies with adult human participants revealed mixed effects regarding the relation between spatial ability and visual instructions. In this study, we investigated this question in primary young children, and particularly we explored how young children with varying levels of spatial abilities integrate information from both static and dynamic visualizations. Children (M = 6.5 years) were instructed to rate their invested mental effort and reproduce the motor actions presented from static and dynamic 3D visualizations. The results indicated an interaction of spatial ability and type of visualization: high spatial ability children benefited particularly from the animation, while low spatial ability learners did not, confirming therefore the ability-as-enhancer hypothesis. The study suggests that an understanding of children spatial ability is essential to enhance learning from external visualizations.

Learning in anatomy can be both spatially and visually complex. Pedagogical investigations have begun exploration as to how spatial ability may mitigate learning. Emerging hypotheses suggests individuals with higher spatial reasoning may attend to images differently than those who are lacking. To elucidate attentional patterns associated with different spatial ability, eye movements were measured in individuals completing a timed electronic mental rotation test (EMRT). The EMRT was based on the line drawings of Shepherd and Metzler. Individuals deduced whether image pairs were rotations (same) or mirror images (different). It was hypothesized that individuals with high spatial ability (HSA) would demonstrate shorter average fixation durations during problem solving and attend to different features of the EMRT than low spatial ability (LSA) counterparts. Moreover, question response accuracy would be associated with fewer fixations and shorter average response times, regardless of spatial reasoning ability. Average fixation duration in the HSA group was shorter than LSA (F(1,8) = 7.99; P = 0.022). Importantly, HSA and LSA individuals looked to different regions of the EMRT images (Fisher Exact Test: 12.47; P = 0.018); attending to the same locations only 34% of the time. Correctly answered questions were characterized by fewer fixations per question (F(1, 8) = 18.12; P = 0.003) and shorter average response times (F(1, 8) = 23.89; P = 0.001). The results indicate that spatial ability may influence visual attention to salient areas of images and this may be key to problem solving processes for low spatial individuals.

Understanding the relationship between cognitive processing and learner performance on tasks using digital media has become increasingly important as the transition towards online learning programs increases. Determining the impact of implementation of instructional resources is often limited to performance outcomes and comparisons to the status quo. This study measured changes in cerebral blood velocity (CBV) of the right middle cerebral artery during visual learning tasks using static images. Transcranial Doppler ultrasonography was used to compare the changes in CBV during learning of individuals with high and low spatial ability. Our results show that there is a slight increase from baseline values of CBV in individuals with high spatial ability during the learning task for the present study. In contrast, individuals with low spatial ability experience a decrement from baseline during the learning task. These results suggest spatial ability mitigates cognitive load and potentially has an impact on learner performance on visual learning tasks.

Spherical video-based virtual reality (SVVR) is an emerging technology in the creation of virtual reality learning contexts. Existing studies have shown that immersion level and spatial ability affect learning performance and experience. Different levels of spatial ability also result in different learning performances and experiences in different levels of immersion, but this interaction effect remains unclear in the SVVR context. We conducted a 2 × 2 factorial experimental study to investigate the interactive effect of immersion level (high vs. low) and students’ spatial ability (high vs. low) on learning performance and experience in the SVVR context. A total of 120 college students participated in the study. The results showed that learning performance, presence, and motivation were significantly higher for high immersion than for low immersion. Learning performance was significantly higher for learners with high spatial ability than for those with low spatial ability. There was a significant interaction effect between immersion level and spatial ability on learning performance. The learning performance of learners with low spatial ability was significantly higher at high immersion than at low immersion. These findings provide a reference for educators to better apply SVVR to their teaching and help them personalize their instruction to students.

IntroductionFor medical and allied health students, knowledge of anatomical variation is important as it may influence physical examination, diagnosis and treatment of patients. Recent studies indicate anatomical variation should be conceptually integrated early into the anatomy curriculum prior to the discipline specific variations taught in surgical and radiological postgraduate training programs. For academic institutions with limited access to cadaveric dissection and anatomy museums, the opportunity for students to appreciate the range of normality in anatomical structures is diminished. Thus, the purpose of this study was to demonstrate how 3D models of anatomical variations may be used to assess structure, function and spatial relationships by incorporating the concept of anatomical variations into assessment paradigms.MethodsTwo 3D digital models depicting upper limb muscular variations, and a 3D teratological model were evaluated by undergraduate kinesiology (KIN) (n = 30), and graduate clinical anatomy (CA) (n = 10) students. The study protocol consisted of the following instruments introduced in sequence: (1) 30‐question Spatial Ability Test (SAT), (2) 16‐question baseline upper limb anatomy test, (3) 13‐question multiple choice quiz based on the displayed 3D models, and (4) Student perception survey (5‐point Likert scale). Based on SAT scores, a median split was used stratify the students into high (KIN: 15, CA: 5) and low spatial ability (KIN: 15, CA: 5). All data are presented as Mean ± SD.ResultsBoth student groups scored similarly on the baseline anatomy knowledge test (KIN: 71 ± 17 %, CA: 71 ± 12%). The mean 3D model quiz scores for KIN students of high spatial ability were 72 ± 16% compared to those of lower spatial ability, 68 ± 14%. The 3D model quiz scores for CA students of high spatial ability were 88 ± 12% compared to CA students of lower spatial ability, 77 ± 15%. The models were perceived as useful in assessing spatial relationships (KIN: 4.4 ± 0.8, CA: 4.9 ± 0.3) and clinical concepts (KIN: 4.0 ± 0.9 CA: 3.9 ± 0.3). Student perceptions were positive for integrating the 3D models into lecture, or laboratory discussions, but KIN students were relatively neutral (3.2 ± 1.2) compared to CA students (3.9 ± 0.3) in their integrated use in bell‐ringer style laboratory assessments. The students expressed interest for a database of explorable 3D models of anatomical variations.ConclusionIntegration of the 3D variant models into anatomy curricula could be a useful means in assessing fundamental anatomical concepts, while demonstrating how deviations in structure can affect normal function. For institutions with computer access but limited cadaveric resources, the 3D models could be powerful supplementary teaching and assessment tools for anatomy students of all education levels and spatial abilities. Furthermore, development of a database of explorable anatomical variations for teaching and learning purposes would be valuable for allied health and medical programs in search of integrating variant anatomy into their anatomy curricula.Support or Funding InformationSupported by: American Association of Anatomists (AAA) Education Research Scholarship; Natural Sciences and Engineering Research Council of Canada (NSERC)This abstract is from the Experimental Biology 2018 Meeting.

In this article, we use eye-tracking technology to analyze the eye movement differences in cognitive maps between high and low level map-based spatial ability participants, revealing key factors of superior spatial ability. It is found that focusing on the perception of spatial structure information, constructing and manipulating complex images psychologically, and positioning by spatial relationship with reference objects are three key factors of superior spatial ability. Based on this, we developed the teaching strategies of geospatial ability to provide reference and suggestions for the education and evaluation of senior high school students' spatial ability.

This study explored an inclusive microwave oven control panel for users with different spatial operation abilities. The experiment has a 2 (spatial operation abilities) × 2 (flash light types) design. The spatial operation abilities encompass high spatial operation ability and low spatial operation ability. This study uses wholistic (W) and analytic (A) cognitive styles that are tested with Riding's computer-administered Cognitive Styles Analysis (CSA) to present low and high spatial operation abilities. Flash light types variable include the flash light and no-flash light types of microwave control panels. The experimental tasks are two typical tasks: a time setting task and a roasting setting task. The experiment results show that both W and A participants had better performances in experimental tasks when they operating the flash light type of microwave oven control panel. This result indicates that the flash light type of microwave oven control panel helps both spatial operation ability users when they conducting both experimental tasks Particularly, it helps the low spatial operation ability users. Therefore, the flash light is suggested to design the microwave oven control panel for all users with different spatial operation abilities.

Many topics in science are notoriously difficult for students to learn. Mechanisms and processes that exist on a scale outside student experience present particular challenges. While instruction often involves visualizations, students typically explain in words, spoken or written. Visualizations have many advantages over verbal explanations, especially for science, so asking students to produce visual rather than verbal explanations should improve their learning. This hypothesis was tested in two domains, a mechanical system and a chemical system. The explanations were analyzed for content, and learning assessed by a post-test. Participants' spatial ability was also assessed as spatial ability often correlates with learning science. For the verbal explaining of a mechanical system, the bicycle tire pump, high spatial participants performed better than low spatial participants. However, low spatial participants performed better and as well as high spatial participants after producing visual explanations. Visual explanations included significantly greater amounts of structural information, as well as other features essential to understanding function, for example a complete explanation of the inlet valve, a crucial but invisible structural component. In the domain of chemical bonding, visual explanations were more effective than verbal explanations, and high spatial ability participants showed greater learning than low spatial ability participants. Visual explanations contained a significantly greater amount of structural information, made reference to specific examples of chemical compounds, and often contained supplementary text. Text added to visual explanations predicted post-test scores, as did the inclusion of invisible features. Many participants who drew identified actual examples of ionic and covalent molecules. Written explanations often used general terms and presentations of definitions. Explanations generated by high spatial ability participants contained greater amounts of function and were more likely to include specific examples. In both domains, text was often spontaneously added to visual explanations. In Experiment 1, added text was equally likely to describe structure or function; in Experiment 2, added text was more likely to describe function. Taken together, the studies provide support for the use of learner-generated visual explanations as a powerful learning tool and suggest that visual explanations are superior because they demand and provide a check for completeness of explanations.

In three experiments we tested the effects of spatial visualization ability on performance of a motion-verification task, in which subjects were shown a diagram of a mechanical system and were asked to verify a sentence stating the motion of one of the system components. We propose that this task involves component processes of (1) sentence comprehension, (2) diagram comprehension, (3) text-diagram integration, and (4) mental animation. Subjects with low spatial ability made more errors than did subjects with high spatial ability on this task, and they made more errors on items in which more system components had to be animated to solve the problem. In contrast, the high-spatial subjects were relatively accurate on all trials. These results indicate that spatial visualization is correlated with accuracy on the motion-verification task and suggest that this correlation is primarily due to the mental animation component of the task. Reaction time and eye-fixation data revealed no differences in how the high- and low-spatial subjects decomposed the task. The data of the two groups of subjects were equally consistent with a piecemeal model of mental animation, in which components are animated one by one in order of the causal chain of events in the system.

This study aims at investigating the difference of creativity between the students treated with the Student-Centered Learning (SCL) strategy and the students treated with the Direct Learning strategy. It was a quasi-experimental study employing the non-equivalent control group design. It was conducted using the 2x2 factorial design. The research population were 40 students attending the course of Fabrication Construction Design. The results of the study showed that (1) The creativity of the students using the SCL strategy attained mean scores of 42.65, higher than the students using the Direct Learning strategy with mean scores of 39. (2) The students with high spatial ability using the SCL strategy attained mean scores of 49, higher than the students using the Direct Learning strategy with mean scores of 36.3. (3) The students with low spatial ability using the SCL strategy attained mean scores of 36.3, lower than the students using the Direct Learning strategy with mean scores of 41.70. (4) There was an interaction between the learning strategy and the spatial ability in terms of the effect on the creativity.

In a 2 × 3 design, we investigated how level of expertise and type of visual presentation influence the tactical learning of a soccer playing system. Nonexpert players benefited more from the two static visualizations than from the dynamic visualization, whereas expert players benefited more from the dynamic rather than static visualizations. Moreover, nonexperts benefited more from the static-with-tracing presentation than from the static-without-tracing presentation, while experts performed at the same level with both types of the static presentation. Results recommend the need to consider levels of player expertise when designing different types of visualization intended to improve learning.

The purpose of this study was to investigate the effects of representation sequences and spatial ability on students’ scientific understandings about the mechanism of breathing in human beings. 130 seventh graders were assigned to two groups with different sequential combinations of static and dynamic representations: SD group (i.e., viewing static representations and then dynamic ones), and DS group (i.e., viewing dynamic representations and then static ones). Among them, 16 students (8 from each group) with different levels of prior knowledge and spatial ability were interviewed. Data sources included a spatial ability test, pre- and post-tests of scientific understandings (involving factual, conceptual, and spatial knowledge), and semi-structured interviews. The statistical results indicated that the SD sequence helped students gain significantly more factual knowledge. The significant interaction effects further suggested that while the representation sequences had no effect on students with low spatial ability, high spatial ability students in the SD group outperformed than their counterparts in DS group on the items of the conceptual and spatial knowledge. Additionally, the analysis of interviews indicated that the representation sequences could affect the foci of students’ explanations and shape their perceptions about the representations. The results suggested interplays among representation sequences, spatial ability, and students’ understandings, and provided insight into the design and arrangement of multiple representations for science learning.

PurposeSpatial perception is an essential skill for professional dentists. The objective of this study was to observe the spatial ability, as well as anatomy module grades, of dental students at a dental education center in Indonesia and relate these to gender and cohort.MethodsA cross-sectional study was carried out where dental students in years (cohorts) 1, 2, 4–6 were invited to take the Revised Purdue Spatial Visualization Test (PSVT-R) and the redrawn Vandenberg and Kuse Mental Rotation Test (MRT) in order to assess spatial ability. In addition, the 1st- and 2nd-year dental students carried out gross anatomy assessments. Spatial ability test results were compared using an independent t-test to detect gender differences, one-way analysis of variance to inspect cohort differences, and correlation relative to anatomy module scores.ResultsA total of 326 dental students voluntarily participated. Statistically significant gender differences were found in both spatial ability tests in the overall sample (PSVT-R: p<0.001; MRT: p=0.001). When the 1st- and 2nd-year dental students were pooled, significant gender differences were detected, in which males scored higher than females in both spatial ability tests (PSVT-R: p<0.001; MRT: p=0.003). In anatomy, however, females scored higher than the males (p=0.005). In addition, there were weak to moderate, but significant correlations between spatial ability tests and anatomy scores.ConclusionThis study indicated that spatial ability may not be the only factor predicting the academic performance of dental students. However, dental students with low spatial ability scores may need supplementary educational techniques when learning specific spatial tasks.
