Using Augmented Reality and Virtual Environments in Historic Places to Scaffold Historical Empathy

The authors explore how 3D visualizations of historical sites can be used as pedagogical tools to support historical empathy. They provide three visualizations created by a team at Virginia Tech as examples. They discuss virtual environments and how the digital restoration process is applied. They also define historical empathy, explain why it is important, and discuss how it is taught.     

‘They might know a lot of things that I don’t know’: investigating differences in preservice teachers’ ideas about contextualizing science instruction in multilingual classrooms

This paper describes the results from a qualitative study of 72 preservice teachers’ initial ideas about contextualizing science instruction with language minority students. Participants drew primarily on local ecological and multicultural contexts as resources for contextualizing instruction. However, preservice teachers enrolled in the bilingual certification program articulated more asset-oriented and less stereotypical ideas than those not seeking bilingual certification. Results can inform teacher education programs that aim to prepare graduates for teaching science in multilingual classrooms.     

School-Contextual Paths to Student Bullying Behaviour: Teachers Under Time Pressure are Less Likely to Intervene and the Students Know It!

ABSTRACT

We assessed whether the level of time-pressure reported by a school’s teachers is predictive of student bullying perpetration. We combined data from two surveys conducted in 129 schools in 2016: the Stockholm School Survey performed among students in grades 9 and 11 (n?=?10,668), and the Stockholm Teacher Survey carried out among senior level (grades 7–9) and upper secondary school (grades 10–12) teachers (n?=?2259). Multilevel path analyses showed that teachers’ stress and time-pressure increased with declining school leadership functioning. Teachers’ level of time-pressure was, in turn, positively associated with student traditional and cyberbullying behaviour, through its effect on the school staff’s tendency (not) to intervene against bullying, but not through the teachers’ stress level. We conclude that schools with leadership that provides opportunities for the teachers to focus on their main mission can counteract bullying among the students and therefore indirectly also to promote student health.     

“We are Just as Confused and Lost as She is”: The Primacy of the Graphic Novel Form in Exploring Conversations Around Deafness

Cece Bell’s (El Deafo, Amulet, New York, 2014) is a middle childhood graphic novel memoir that explores the author’s experiences of losing her hearing and growing up with a severe hearing loss. As a graphic novel, the story is able to avoid a medicalized view of disability by combining image and text, a format that allows readers, those with hearing and those without, to step inside the narrative and deeply consider Bell’s experiences. The narrative elements typically found in graphic novel autobiography create a communal reading experience, which does not allow readers to forget who the book is about. After an analysis of the primacy of these narrative graphic novel elements in telling a story about a disability, this article shares the reading experiences of university students in exploring this story, during which students used both the image and text to help them confront misconceptions they had about deafness, broadening their understandings and experiences around disability.     

Effective schools,school segregation,and the link with school achievement

This study examines whether 3 teacher-rated aspects of school effectiveness differ across school segregation profiles in Stockholm, and to what extent these indicators are associated with the academic achievement of 9th-grade students. Analyses were based on 2 cross-sectional data collections performed in 2014 and 2016, respectively (147 school units), one among teachers (n = 2,024) and the other among 9th-grade students (n = 9,151). Multilevel analysis was applied, estimating 2-level random intercept linear regression models. Results show that teachers’ ratings of school leadership, teacher cooperation, and school ethos, as well as student-reported marks differ across school segregation profiles. Findings further reveal significant associations between these school effectiveness indicators and student performance, even when taking student family background and the school’s student body composition into consideration. In part, these associations are also identified within segregation profiles. Moreover, results show that school ethos acts as a mediator between school segregation profile and student achievement.     

Design implications from a usability study of GramStain-TutorTM

To examine interface issues in an educational software program, we recruited twenty-two users in health sciences departments for a usability study. Using the GramStain-Tutor™ (GST) CD-ROM, these users performed tasks in navigating the program and using various interactive features. Their actions and comments were recorded with a digital video recorder and an audio recorder. The main results of our study are: (a) the majority of the users did not use the multiple navigational options available in the program; (b) navigational patterns differed based on the training background and content knowledge of the users; (c) several visual cues critical to program use were not discovered by the majority of the users; and (d) icons representing specific functions were not intuitive from users' perspectives. We demonstrated how a usability study of a relatively small number of users can identify specific problems in interface design. We recommend these interface problems be addressed before conducting educational studies that examine how educational software programs affect student learning.     

Double degrees: double the trouble or twice the return?

Double degrees (also called joint or combined degrees)—programs of study combining two bachelor degrees—are increasingly popular in Australian universities, particularly among women. A case study using qualitative and quantitative surveys of current and past double degree students is presented. The study indicates that double degrees benefit students in providing a broad education and increasing skills and options. However, benefits are not fully realised because of administrative difficulties, lack of support and absence of ‘learning communities’. These problems arise because double degrees sit outside the disciplinary structure of universities. As such, however, double degrees have potential to provide transdisciplinary education. We suggest initiatives that would improve the experience, performance and persistence of double degree students. They would also build the skills of integration, boundary work, communication and teamwork associated with transdisciplinarity. These skills not only equip students for a range of employment; they are sorely needed in society.

Time horizon and choice by pigeons in a prey-selection task

In two operant simulations of prey selection, the choice behavior of pigeons and the predictions of a model of the effect of session length on optimal prey selection were compared. All but one of the predictions were confirmed. In the first experiment, a higher proportion of “bad” items (comparatively long delays to food) was accepted in 10-min sessions in one operant chamber than in the first 10 min of 20-min sessions in a different chamber. The proportion of bad items accepted increased toward the end of the 20-min sessions. In the second experiment, the birds were exposed both to 20-min sessions in one distinctively marked operant chamber and to sessions of variable length, with a mean of 20 min, in another. A higher proportion of bad items was accepted in the variable-session chamber than in the fixed-session chamber at the beginning of the 20-min sessions. This difference decreased toward the end of the sessions but did not reverse as expected. In both experiments, an independent test analogous to the peak procedure was administered to establish whether the birds discriminated among the different session lengths.
