Spatial reasoning skills have been linked to success in STEM and are considered an important part of geoscience problem solving. Most agree that these are a group of skills rather than a single ability, though there is no agreement on the full list of constituent skills. Few studies have attempted to isolate specific spatial skills for deliberate training. We conducted an experiment to isolate and train the skill of recognizing horizontal (a crucial component in measuring the orientation of planes) using a dedicated Virtual Reality (VR) module. We recruited 21 undergraduate students from natural science and social science majors for the study, which consisted of a pretest, 15-minute training, and posttest. The pre- and posttests consisted of a short multiple choice vocabulary quiz, 5 hand-drawn and 5 multiple choice Water Level Task (WLT) questions, and the Vandenberg and Kuse Mental Rotation Task (MRT). Participants were sorted based on pre-test Water Level Task scores, only those with scores <80% were placed in an intervention group and randomly assigned to training, either in VR (experimental) or on paper (standard), of about 15 minutes. The high-scoring participants received no training (comparison). All three groups of participants completed a posttest after the training (if any). After removing three participants who did not return for the posttest session, we had 18 participants in total: 6 in VR, 7 in the comparison group, and 5 in the standard group. Repeated measures ANOVA of the pre to post hand-drawn WLT scores shows at least one group is different (p=.002) and Tukey’s Post-Hoc analysis indicates that the VR group improved significantly more that the high-scoring comparison group (Mean Difference = -1.857, p = .001) and the standard group (Mean Difference = -1.200, p = .049). While any significant result is encouraging, a major limitation of this study is the small sample size and unequal variances on both the pretest (Levene’s HOV test, F = 7.50, p = .006) and posttest (F = 13.53, p < .001), despite random assignment. More trials are needed to demonstrate reproducibility. While more tests are needed, this preliminary study shows the potential benefit of VR in training spatial reasoning skills.

SPATIAL SKILL BUILDING IN GEOSCIENCE USING VR: MEASURING STRIKE AND DIP
Measuring strike and dip is a common but complicated spatial task introduced to students in undergraduate geology courses. Students must employ multiple spatial reasoning skills in addition to geology-specific content knowledge. These spatial skills include disembedding - to recognize a suitable bedding or foliation plane to measure, spatial perception - to understand the plane’s relationship to horizontal and vertical, and aspects of spatial visualization, perspective taking, and mental rotation to determine how to position and read the compass tool. We tested a virtual reality (VR) training module to help teach the use of the compass tool to measure strike and dip. Students in a large introductory course in a public university were placed by lab section into either a “standard” classroom instruction or VR instruction for their initial training, then all completed a simplified mapping exercise in which they measured five planes set up around the classroom. Pre and post tests of spatial skills and scores on the measurement portion of the map assignment were collected and compared between the 2 types of training groups. Of 12 lab sections, half were assigned to VR and the other half to standard. The instructional assistants each taught at least one section of each type, and the instruction types were distributed evenly across the scheduled lab times. The VR group showed 11% higher improvement scores on the Water Level Task (WLT) compared to the standard group (p = 0.008, n=159). Because students in some lab sections had identical responses to the strike and dip task, we used a subset of four lab sections in which students submitted unique responses (n=41). We found no significant differences on the strike and dip task except with application of the right hand rule (RHR). The classroom instruction group performed 26% higher on the strike task when the RHR was taken into account (p = 0.006), but this difference does not persist when scoring is agnostic to the RHR. The VR module contains only a text explanation of the RHR. These results suggest that VR is at least as good as classroom instruction for building geology skills and, through targeted instruction, can significantly impact performance on a spatial test. Feedback on the VR activity will be used to further refine the module and develop best practice strategies for VR spatial training.

We tested the impact of a 15-minute VR training on spatial skills and performance on a geoscience task with a control group. The VR group improved more on the Water Level Task-a measure of understanding of horizontal (B = 0.68, p=0.008). Both groups performed equally on the geology task, except for an orientation rule not well instructed in the VR module (B = -1.33, p=0.0057). In the post-survey, the VR group reported higher ability to link knowledge (X2=4.45, p=0.035) and more interest than in past activities (X2=8.47, p=0.004). This is encouraging, given the brevity of the VR lesson.more » « less

null (Ed.)Spatial reasoning skills contribute to performance in many STEM fields. For example, drawing sectional views of three-dimensional objects is an essential skill for engineering students. There is considerable variation in the spatial reasoning skills of prospective engineering students, putting some at risk for compromised performance in their classes. This study takes place in a first-year engineering Spatial Visualization course to integrate recent practices in engineering design education with cognitive psychology research on the nature of spatial learning. We employed three main pedagogical strategies in the course - 1) in class instruction on sketching; 2) spatial visualization training; and 3) manipulation of physical objects (CAD/3D print creations). This course endeavors to use current technology, online accessibility, and implementation of the three pedagogical strategies to bring about student growth in spatial reasoning. This study is designed to determine the effect of adding two different spatial reasoning training apps to this environment. Over 230 students (three sections) participated in our study. In two of the three sections, students received interactive spatial visualization training using either a spatial visualization mobile touchscreen app in one section or an Augmented Reality (AR) app in the other section. Research suggests that there are benefits to using the Spatial Vis Classroom mobile app for college students.The app has been shown to increase student persistence resulting in large learning gains as measured by the Purdue assessment of spatial visualization (PSVT-R), especially for students starting with poor spatial visualization skills. The Spatial Vis Classroom app can be used in the classroom or assigned as homework. The AR app is designed to help users develop their mental rotation abilities. It is designed to support a holistic understanding of 3-dimensional objects, and research has shown that, in combination with a traditional curriculum, it increases students’ abilities also measured by the PSVT-R. Of particular interest, the data suggest that the app overcomes the advantage found by males over females in a traditional class alone focused on spatial reasoning. Both of the course sections were required to use the apps for approximately the same time in class and outside of class. Students in the control section were required to do hand sketching activities in class and outside of class, with roughly the same completion time as for the sections with the apps. Students grades were not affected by using the three different approaches as grading was based on completion only. Based on current literature, we hypothesize that overall benefits (PSVT-R gains) will be comparable across the 3 treatments but there will be different effects on attitude and engagement (confidence,enjoyment, and self-efficacy). Lastly, we hypothesize that the treatments will have different effects on male/female and ethnic categories of the study participants. The final paper will include an analysis of results and a report of the findings.more » « less

Historically, physics education primarily consisted of lectures in which students have a largely passive role. Proponents of educational reform have rallied around active learning to increase engagement and retention in STEM fields, particularly advocating peer interactions to build a foundation of deep understanding. However, little is known about how students' prior preparation for introductory courses impacts their mastery of course material when instructors incorporate active learning. In the present study, we examine learning outcomes in two sections of an introductory mechanics course at an institution with a wide range of students' prior mathematics preparation as assessed by quantitative SAT scores. For each of three years, one section was taught using peer instruction in which much of the class time was spent in small-group discussions between students. The other section was taught by the same instructor using interactive lectures in which discussions primarily took place between volunteers from the class and the instructor. We find that students enrolled in the peer instruction sections earned lower grades in the course than did students in the interactive sections. We also find students in the peer instruction sections with lower quantitative SAT scores showed lower gains in understanding foundational concepts as assessed by the Force Concept Inventory and were less likely to earn an A in the course than comparable students in the interactive sections. While further research is needed to confirm these results, this study suggests that peer instruction might not be the optimal pedagogy for heterogeneous populations.more » « less

Shaffer, Justin (Ed.)ABSTRACT Argumentation is vital in the development of scientific knowledge, and students who can argue from evidence and support their claims develop a deeper understanding of science. In this study, the Argument-Driven Inquiry instruction model was implemented in a two-semester sequence of introductory biology laboratories. Student’s scientific argumentation sessions were video recorded and analyzed using the Assessment of Scientific Argumentation in the Classroom observation protocol. This protocol separates argumentation into three subcategories: cognitive (how the group develops understanding), epistemic (how consistent the group’s process is with the culture of science), and social (how the group members interact with each other). We asked whether students are equally skilled in all subcategories of argumentation and how students’ argumentation skills differ based on lab exercise and course. Students scored significantly higher on the social than the cognitive and epistemic subcategories of argumentation. Total argumentation scores were significantly different between the two focal investigations in Biology Laboratory I but not between the two focal investigations in Biology Laboratory II. Therefore, student argumentation skills were not consistent across content; the design of the lab exercises and their implementation impacted the level of argumentation that occurred. These results will ultimately aid in the development and expansion of Argument-Driven Inquiry instructional models, with the goal of further enhancing students’ scientific argumentation skills and understanding of science.more » « less
