Many students persistently misinterpret histograms. This calls for closer inspection of students’ strategies when interpreting histograms and case-value plots (which look similar but are diferent). Using students’ gaze data, we ask: How and how well do upper secondary pre-university school students estimate and compare arithmetic means of histograms and case-value plots? We designed four item types: two requiring mean estimation and two requiring means comparison. Analysis of gaze data of 50 students (15–19 years old) solving these items was triangulated with data from cued recall. We found five strategies. Two hypothesized most common strategies for estimating means were confirmed: a strategy associated with horizontal gazes and a strategy associated with vertical gazes. A third, new, count-and-compute strategy was found. Two more strategies emerged for comparing means that take specific features of the distribution into account. In about half of the histogram tasks, students used correct strategies. Surprisingly, when comparing two case-value plots, some students used distribution features that are only relevant for histograms, such as symmetry. As several incorrect strategies related to how and where the data and the distribution of these data are depicted in histograms, future interventions should aim at supporting students in understanding these concepts in histograms. A methodological advantage of eye-tracking data collection is that it reveals more details about students’ problem-solving processes than thinking-aloud protocols. We speculate that spatial gaze data can be re-used to substantiate ideas about the sensorimotor origin of learning mathematics.

With the increase of Virtual Reality (VR), the importance of advertising within VR has become more relevant. However, it is unclear whether advertising strategies used in traditional media also work in VR. This study is focused on openness in advertisements, an advertisement strategy that refers to the degree of guidance towards the intended message. More open means less guidance and is often used to increase attention and attitude. However, open ads have not been researched in VR before. In this study, VR-advertisements were created and tested that differ in openness. An experiment with 87 participants revealed new ways of creating openness based on positioning and timing of anchoring cues. Moreover, the results revealed a negative effect of openness on interpretation, consistent with findings in studies using traditional media. Unexpectedly, openness in VR-advertisements did not influence (ad and brand) attitude, possibly due to the newness-effect causing high appreciation for ads in VR.

Ethnographic fieldwork is a balancing act between distancing and immersing. Fieldworkers need to come close to meaningfully grasp the sense-making efforts of the researched. In methodological textbooks on ethnography, immersion tends to be emphasized at the expense of its counterpart. In fact, ‘distancing’ is often ignored as a central tenet of good ethnographic conduct. In this article we redirect attention away from familiarization and towards ‘defamiliarization’ by suggesting six estrangement strategies (three theoretical and three methodological) that allow the researcher to develop a more detached viewpoint from which to interpret data. We demonstrate the workings of these strategies by giving illustrations from Machteld de Jong’s field- and text-work, conducted among Moroccan-Dutch students in an institution of higher vocational education.

expressiveness, performance, musicians, skills, educationUsing the genre of Improvisational theatre as a basis, my research aims to design and develop instructional strategies that would help students enhance their expressive skills and achieve the flexibility to adapt their motor behavior to the musical piece. Embodying diverse characters and physicalities, as well as affective states or fictional realities through improv theatre exercises should enable them to expand their expressive range and, therefore, better convey their interpretation to their audience. Through this process, this study also seeks to gain an understanding of the effect this type of training may have on musicians' performance experience, as well as its implications in other areas of their development.
