Keeping your audience in mind: applying audience analysis to the design of interactive score reports
Score reports have one or more intended audiences: the people who use the reports to make decisions about test takers, including teachers, administrators, parents and test takers. Attention to audience when designing a score report supports assessment validity by increasing the likelihood that score users will interpret and use assessment results appropriately. Although most design guidelines focus on making score reports understandable to people who are not testing professionals, audiences should be defined by more than just their lack of statistical knowledge. This paper introduces an approach to identifying important audience characteristics for designing computer-based, interactive score reports. Through three examples, we demonstrate how an audience analysis suggests a design pattern, which guides the overall design of a report, as well as design details, such as data representations and scaffolding. We conclude with a research agenda for furthering the use of audience analysis in the design of interactive score reports. 相似文献

Hand paddles and parachutes have been used in order to overload swimmers, and consequently increase the propulsive force generation in swimming. However, their use may affect not only kinematical parameters (average speed, stroke length and stroke rate), but also time gaps between propulsive phases, assessed through the index of coordination (IdC). The objective of this study was to assess the effects of hand paddles and parachute use, isolated or combined, on kinematical parameters and coordination. Eleven swimmers (backstroke 50-m time: 29.16 ± 1.43 s) performed four 15-m trials in a randomised order at maximal intensity: (1) without implements (FREE), (2) with hand paddles (HPD), (3) with parachute (PCH) and (4) with hand paddles plus parachute (HPD+PCH). All trials were video-recorded (60 Hz) in order to assess average speed, stroke rate, stroke length, five stroke phases and index of coordination. When average swimming speed was compared to FREE, it was lower in PCH and HPD+PCH, and higher in HPD. Stroke rate decreased in all overloaded trials compared to FREE. The use of hand paddles and parachute increased and decreased stroke length, respectively. In addition, propulsive phase duration was increased when hand paddles were used, and time gaps shifted towards zero (no time gap), especially when hand paddles were combined with parachute. It is conceivable that the combined use of hand paddles and parachute, once allowing overloading both propulsive and resistive forces, provides a specific stimulus to improve muscle strength and propulsive continuity. 相似文献

Two experiments examined the effects of a multimedia technology referred to as “Time Compressed Animated Delivery” (TCAD),
on student learning in a junior-level reproductive physiology course. In experiment 1, participating students received one
of two presentations of the same instructional material: TCAD and a lecture captured on video. At the completion of each presentation
a test was administered and group mean test scores computed and compared. The results were statistically significant (df = 362, t = 10.623, p < 0.05), favoring the TCAD treatment group. The effect size estimate was 1.14. In experiment 2, student learning from three
groups were compared on the same reproductive physiology unit used in experiment 1: (1) TCAD, (2) TCAD without the 3-D component,
and (3) video-lecture. After removal of three poor functioning items, a one-way analysis of variance was computed. The results
were statistically significant (df = 2, F = 2.351, p < 0.10). Results of post hoc comparisons showed that differences in mean test scores between the TCAD and control groups
were statistically significant (p < 0.05). The effect size estimate was 0.25. These findings provide preliminary evidence for use of TCAD. 相似文献

Sleep in adolescents has been shown to be an important factor when looking at physical, mental, and social well‐being. Little evidence is found regarding sleep patterns in adolescents from households facing extreme poverty, where conditions such as crowding, poor housing, sanitation or education, and precarious employment set an adverse environment for sleep. In this study, we sought to assess in a nationwide sample comprised of 1,682 adolescents from Argentina, how the presence of extreme poverty—as defined by the presence of unsatisfied basic needs (UBN)—affects the relationship of sleep duration with school, work, and other daily activities. A global high prevalence of short sleeping time, a slight increase of sleep time in adolescents with UBN, and different patterns of wake activities that predict sleep deficit, depending on the presence of UBN, were found. The poor academic achievement, increased risk of accidents, and adverse health outcomes associated with sleep deprivation support the view that sleep is an additional unsatisfied basic need that worsens living conditions at this age. The results may help to design public health policies that contribute to ameliorate this adverse situation. 相似文献
