Complex perceptual tasks, like clinical reasoning based on visual observations of patients, require not only conceptual knowledge about diagnostic classes but also the skills to visually search for symptoms and interpret these observations. However, medical education so far has focused very little on how visual observation skills can be efficiently conveyed to novices. The current study applied a novel instructional method to teach these skills by showing the learners how an expert model visually searches and interprets symptoms (i.e., eye-movement modelling examples; EMMEs). Case videos of patients were verbally explained by a model (control condition) and presented to students. In the experimental conditions, the participants received a recording of the model’s eye movements superimposed on the case videos. The eye movements were displayed by either highlighting the features the model focused on with a circle (the circle condition) or by blurring the features the model did not focus on (the spotlight condition). Compared to the other two conditions, results show that a spotlight on the case videos better guides the students’ attention towards the relevant features. Moreover, when testing the students’ clinical reasoning skills with videos of new patient cases without any guidance, participants studying EMMEs with a spotlight showed improved their visual search and enhanced interpretation performance of the symptoms in contrast to participants in either the circle or the control condition. These findings show that a spotlight EMME can successfully convey clinical reasoning based on visual observations. 相似文献

ABSTRACTThe aim of the study is to analyse teachers’ efforts to develop secondary school students’ knowledge and argumentation skills of what constitutes scientific theories. The analysis is based on Leontiev’s three-level structure of activity (activity, action, and operation), as these levels correspond to the questions why, what, and how content is taught. The unit of analysis was a school development project in science education, where design-based interventions were conducted. Data comprised notes and minutes from eight meetings, plans, and video recordings of the lessons, and a written teacher evaluation. The teachers’ (n = 7) learning actions were analysed to identify (a) concept formation in science education, (b) expressions of agency, (c) discursive manifestations of contradictions, and (d) patterns of interaction during the science interventions. Three lessons on what constitutes scientific theories were implemented in three different student groups (n = 24, 23, 24), framed by planning and evaluation meetings for each lesson. The results describe (1) the ways in which teachers became more skilled at ensuring instruction met their students’ needs and (2) the ways in which teachers’ operations during instruction changed as a result of their developed knowledge of how to express the content based on theoretical assumptions. 相似文献

In this paper we explored text production differences in an expository text production task between writers who looked mainly
at the keyboard and writers who looked mainly at the monitor. Eye-tracking technology and keystroke-logging were combined
to systematically describe and define these two groups in respect of the complex interplay between text production and the
reading of one’s own emerging text. Findings showed that monitor gazers typed significantly faster and were more productive
writers. They also read their own text more, and they frequently read in parallel with writing. Analysis of fixation durations
suggests that more cognitive processing is in use during reading in parallel with writing than during reading in pauses. Keyboard
gazers used the left and right cursor keys significantly more. We suggest that this is because they revised their texts in
a much more serial mode than monitor gazers. Finally, analysis of the characteristics of the final texts showed no differences
between the groups. 相似文献

We use eye tracking as a method to examine how different mathematical representations of the same mathematical object are attended to by students. The results of this study show that there is a meaningful difference in the eye movements between formulas and graphs. This difference can be understood in terms of the cultural and social shaping of human perception, as well as in terms of differences between the symbolic and graphical registers. 相似文献

Objective. There is a need for better understanding the relation between parents’ mentalizing about their child and their actual behavior toward the child. Specifically, it is important to understand the significance of mentalization about discrete parental challenges in comparison with mentalization about the relationship in general in relation to their interaction with the child. This study aimed to examine parental mentalization and observed emotional availability. Design. Forty mothers were observed in a play situation with their children (aged 3–10 years) to rate the emotional availability in the interaction. Mothers were also interviewed with the parent development interview and about parental limit setting to assess parental reflective functioning. Results. Analyses showed moderate correlations between the reflective functioning scores and the emotional availability dimensions. Approximately 15% of the variance in emotional availability scales could be accounted for by the reflective functioning ratings. Conclusions. The results suggest that parents’ ability to mentalize about limit setting behaviors may affect interactions between the parent and child. 相似文献

PISA results show that a considerable number of 15-year-old pupils after 8 to 10 years of schooling have a low level of functional reading literacy, as defined in the PISA framework. While PISA results help identify the level of reading competency, they do not reveal what might be the reasons why some students fail to solve the tasks. One way to explore the difficulties students encounter while solving PISA reading tasks is to track their eye movements during reading. The main aim of this study was to explore the similarities and differences in eye movement patterns between students with high and low scores on PISA reading tasks. A sample of 92 students took part in the pre-test, which was based on PISA items, and administered to identify groups of students with high and low PISA reading scores. Based on student pre-test results, 20 students were selected for the main, eye-tracking test—10 participants with low scores and 10 with high scores. The eye-tracking test consisted of four different released PISA reading tasks, three of them continuous and one non-continuous. The continuous items were followed by one multiple-choice question each at L1, L2, and L3 levels of difficulty. The non-continuous text was followed by three multiple-choice questions (also L1–L3).Three main findings were the following: regarding saccadic amplitudes, the reading was found to be less fluent for the low-skilled group; according to the heat maps, they had difficulty finding the relevant material; and taking into account standard deviations of eye-tracking measures, the variability was found to be larger in this group. Taken together, the findings of this study show that the PISA results differentiating low- and high-scoring groups go hand in hand with insights from more fine-grained eye-tracking measurements. 相似文献

The eye-tracking method was used to assess the influence of detailed, colorful illustrations on reading behaviors and learning outcomes. Based on participants’ subjective ratings in a pre-study, we selected eight one-page human anatomy lessons. In the main study, participants learned these eight human anatomy lessons; four were accompanied by detailed illustrations, and the other four were accompanied by simplified illustrations. Participants completed a comprehension test and an evaluation questionnaire after reading each lesson. The results showed that detailed and simplified illustrations were equally effective in terms of learning outcomes. Eye-tracking data indicated that the detailed illustrations attracted attention in the initial learning stage and received more visual attention during the overall learning process. Notably, correlation analysis revealed that spending a greater proportion of time re-inspecting the simplified illustration was associated with higher test performances. By contrast, greater proportion of time spent re-inspecting the detailed illustration was not significantly correlated with learning outcomes. The results suggest that detailed illustrations could influence the learning process, and may support learning differently compared with simplified illustrations. 相似文献

Exhaustive exercise is associated with a persistent sensation of weakness and sometimes nausea suggesting abdominal vagal activity. We measured plasma indices of sympathoadrenal (adrenaline, noradrenaline, dopamine) and vagal (pancreatic polypeptide) activity before, during and after submaximal and maximal exercise in healthy young subjects. Plasma adrenaline, noradrenaline and dopamine increased to 8.5 (range 7.4–40.5), 48.0 (32.3–100.5) and 1.8 (1.2–6.6) nmol l–1 respectively (n = 5), during maximal exercise and decreased towards control values within 15 min of rest. Pancreatic polypeptide (n = 10) increased only during maximal exercise and reached its highest value, 48 (21–145) pmol l–1, after exertion. The results conform to an increase in sympathetic activity during exercise and a persistent vagal activity after intense exercise which could contribute to the sensation of weakness. 相似文献

This study presents findings from analyses of naturally occurring literacy events, where children jointly focus on reading and writing letters of the alphabet, illustrating social constructions of learning created through language and embodied action. Video recorded data from two different families living in an urban low-income area in Tanzania is presented to illustrate the findings. The analysis shows how participation frameworks are negotiated in terms of symmetries and asymmetries between younger and older siblings with both older and younger siblings initiating these frameworks: older siblings using different directives to guide the younger child's focus of attention and younger children both following and resisting such strategies. 相似文献

An eye-tracking study with 60 native Swedish speakers (18–30 years) was conducted to investigate the positive effects on learning outcomes predicted by the disfluency effect. Subtle low-pass filtering was used as a disfluency manipulation and compared with a control condition using regular text. The text was presented on four separate text presentation screens (TPSs), and eye movements were recorded. A free recall task was given 25 min later, and working memory capacity (WMC) was assessed to test if it would moderate learning outcomes. The disfluency manipulation had no effect on learning outcomes, total reading times on words or lines, first- or second-pass reading on lines, or average fixation durations. Moreover, the disfluency effect was not moderated by students’ WMC or self-reported prior knowledge of the topic. However, an adaptation to the disfluency manipulation was found. Total reading times on both words and lines were shorter in TPS 1 and 2 in the disfluency condition compared with the control condition, whereas reading times were longer in TPS 3 and 4. It is discussed if failures to replicate the disfluency effect arise from material features, with positive adaptations to disfluency (i.e., higher effort investment) possibly requiring more comprehensive materials. 相似文献
