Premature closure and guided reinvention: a case study in a web‐based learning environment

Just as linguistic errors have provided insights into the nature of linguistic competence(s), detailed analyses of blind spots or marked trajectories in the reflection cycles of novice teachers may provide a window on their underlying beliefs, and thus on relevant zones of proximal development. In this paper we analyse a case study in an experimental web‐based learning environment in which a novice teacher demonstrably just reproduces the assumptions she started out with rather than re‐inspecting them. Having located a problem of motivation uniquely inside the learners’ heads, she pointedly ignores hints in the feedback that her own verbal and nonverbal behaviour in the classroom might be a relevant domain of enquiry. Our findings show the need for structural interventions within a priori hypothesized, linearly ordered, stages in reflection models. We report on two small‐scale experiments that implement suggested changes in the architecture of the web site which yield more context‐sensitive ways of scaffolding reflection. In conclusion we argue that detailed discursive accounts of successful and less successful reflection trajectories are needed to refine and further develop models in teacher thinking.     

A high resolution laser scanning model of the Roman theater in Pinara,Turkey – comparison to previous measurements and search for the causes of damage

The archaeological site Pinara, southwest Turkey, which includes several remarkable objects of cultural heritage, has been the focus of several previous archaeoseismic studies. One of these examined the setting of the Roman theater in the east of Pinara by a lidar survey. A gross inclination of the stone rows of the auditorium of 0.81° towards N 314°E was interpreted as a consequence of recent coseismic tectonic movements. A new survey of the theater with a terrestrial phase laser scanner is the basis for a model with 15 times higher resolution and 28 times more data points. Parallel to the fieldwork in this study, the process and accuracy of the leveling of the 3D point clouds produced by the scanner was tested in a series of experiments. Based on the orientation of the blocks forming the seats of the theater, we suggest six sections with changing average inclination of the seats and a fault line separating a northern and a southern section. While the previously found overall inclination of the auditorium is confirmed by the new model and the dip direction agrees, the inclination is 0.58° compared to previously determined 0.81°. The almost perfect increase of inclination with the height of the first 10 entire seating rows and the nearly constant inclination from row 11 onward, makes systematic measurement errors during the construction a possible cause. This is an alternative scenario to the interpretation of a coseismic displacement of the conglomerate block on which the theater was built.     

HPT and small business: Gold mine or land mine?

Performance consulting is typically applied to large organizations. Almost all of the literature on the topic discusses the art and science of human performance technology in these types of organizations. In the United States, however, 99.7% of employer organizations are small businesses. This article addresses some of the opportunities and challenges of working with smaller organizations and presents ways that performance consultants can build a sustainable practice in this market.     

Kawaii Killers and Femme Fatales: A Textual Analysis of Female Characters Signifying Benevolent and Hostile Sexism in Video Games

ABSTRACT

Game developers potentially convey socio-cultural values about gender through design choices. This study interpreted the designs of 11 purposively selected female game characters, developed by studios located in the United States and Japan, through the lens of ambivalent sexism. This social psychological theory posits that sexism consists of hostile and benevolent attitudes about women. Two themes emerged across characterizations: bodies as objects, bodies as weapons and (in)dependence. Both consisted of empowering qualities paired with problematic beliefs about women. This analysis contributes to interdisciplinary literature by using an empirical perspective to interpret gender representations in video games.     

Text Analysis in R

Computational text analysis has become an exciting research field with many applications in communication research. It can be a difficult method to apply, however, because it requires knowledge of various techniques, and the software required to perform most of these techniques is not readily available in common statistical software packages. In this teacher’s corner, we address these barriers by providing an overview of general steps and operations in a computational text analysis project, and demonstrate how each step can be performed using the R statistical software. As a popular open-source platform, R has an extensive user community that develops and maintains a wide range of text analysis packages. We show that these packages make it easy to perform advanced text analytics.     

An Insidious Poison or a Door to the Story?

The aim of this paper is to grasp the influence of the newsroom on frame-building processes. First, journalists’ own understanding of “frames” and “framing” is discussed. Second, from an academic interpretation of these concepts, journalists’ framing practices are studied. To this end an ethnographic study was conducted at two newsrooms, one in Belgium and one in the Netherlands. The findings reveal that while the noun “frame” is sporadically used as a tool, the verb “framing” is considered as something from which a journalist should refrain. This is explained by the associations journalists make with strategic framing from sources as well as by the newspapers’ explicit attempt to no longer view the world from a single ideological frame. It is argued that the studied newsrooms have replaced ideology by, respectively, a counterframing strategy that strives to disprove existing frames (deframing) and a narrative approach that, one the one hand, sharpens existing frames but, on the other hand, offer more opportunities to create alternative frames (reframing) for events.

Cinematic Rendering in Anatomy: A Crossover Study Comparing a Novel 3D Reconstruction Technique to Conventional Computed Tomography

Integration of medical imaging into preclinical anatomy courses is already underway in many medical schools. However, interpretation of two-dimensional grayscale images is difficult and conventional volume rendering techniques provide only images of limited quality. In this regard, a more photorealistic visualization provided by Cinematic Rendering (CR) may be more suitable for anatomical education. A randomized, two-period crossover study was conducted from July to December 2018, at the University Hospital of Erlangen, Germany to compare CR and conventional computed tomography (CT) imaging for speed and comprehension of anatomy. Sixteen students were randomized into two assessment sequences. During each assessment period, participants had to answer 15 anatomy-related questions that were divided into three categories: parenchymal, musculoskeletal, and vascular anatomy. After a washout period of 14 days, assessments were crossed over to the respective second reconstruction technique. The mean interperiod differences for the time to answer differed significantly between the CR–CT sequence (−204.21 ± 156.0 seconds) and the CT–CR sequence (243.33 ± 113.83 seconds; P < 0.001). Overall time reduction by CR was 65.56%. Cinematic Rendering visualization of musculoskeletal and vascular anatomy was higher rated compared to CT visualization (P < 0.001 and P = 0.003), whereas CT visualization of parenchymal anatomy received a higher scoring than CR visualization (P < 0.001). No carryover effects were observed. A questionnaire revealed that students consider CR to be beneficial for medical education. These results suggest that CR has a potential to enhance knowledge acquisition and transfer from medical imaging data in medical education.     

Problems in the context evaluation of individualized courses

From 1970 to 1974 an Individualized Study System (ISS) for mathematics courses for first year engineering students was developed. Because of changes in the curriculum, new courses had to be developed from August 1974. The context evaluation of these new courses (ISS-calculus) consisted mainly of the evaluation of the mathematics courses developed during the preceding years. After a year the Department decided to suspend ISS as a teaching system for calculus partly because of dissatisfaction of the teachers with ISS-calculus.This paper consists of two parts. Part one (sections 1,2) is a case study and summarizes the development of the system from 1970 to 1975. It examines in detail the problems encountered in this development with special attention to the role of the executive teacher. The organization of an ISS-course and the planning decisions to be taken become more complex according to the number of executive teachers. In part two (sections 3,4) we provide a classification of ISS courses to illustrate the complexity of the system and we offer some general advice on the management of individualized study systems.
