From a theoretical viewpoint, educational interfaces that facilitate communicative actions involving representations central
to a domain can maximize students’ effort associated with constructing new schemas. In addition, interfaces that minimize
working memory demands due to the interface per se, for example by mimicking existing non-digital work practice, can preserve
students’ attentional focus on their learning task. In this research, we asked the question: What type of interface input capabilities provide best support for science problem solving in both low- and high-performing students? High school students’ ability to solve a diverse range of biology problems was compared over longitudinal sessions while
they used: (1) hardcopy paper and pencil (2) a digital paper and pen interface (3) pen tablet interface, and (4) graphical
tablet interface. Post-test evaluations revealed that time to solve problems, meta-cognitive control, solution correctness,
and memory all were significantly enhanced when using the digital pen and paper interface, compared with tablet interfaces.
The tangible pen and paper interface also was the only alternative that significantly facilitated skill acquisition in low-performing
students. Paradoxically, all students nonetheless believed that the tablet interfaces provided best support for their performance,
revealing a lack of self-awareness about how to use computational tools to best advantage. Implications are discussed for
how pen interfaces can be optimized for future educational purposes, and for establishing technology fluency curricula to
improve students’ awareness of the impact of digital tools on their performance. 相似文献

Supervisory skills play an important role in individual staff development and the achievement of organizational objectives. These skills are vital to professionals in community college student affairs, who support a diverse student population and a wide array of programming. This study was conducted to describe the kind of supervisory training experience student affairs professionals received. Through interviews with community college student affairs professionals, we found that many experienced a lack of formal training and acquired supervisory skills over time on the job, through trial and error, and from workshops. 相似文献

The ability to compare published group-level estimates of objectively measured moderate-to-vigorous physical activity (MVPA) across studies continues to increase in difficulty. The objective of this study was to develop conversion equations and demonstrate their utility to compare estimates of MVPA derived from the wrist and hip. Three studies of youth (N = 232, 9-12yrs, 50% boys) concurrently wore a hip-worn ActiGraph and a wrist-worn GENEActiv for 7-days. ActiGraph hip count data were reduced using four established cutpoints. Wrist accelerations were reduced using the Hildebrand MVPA 200 mg threshold. Conversion equations were developed on a randomly selected subsample of 132 youth. Equations were cross-validated and absolute error, absolute percent error, and modified Bland-Altman plots were evaluated for conversion accuracy. Across equations R2adj was 0.51–0.56 with individual-level absolute error in minutes ranging from 7 (wrist-to-hip Puyau) to 14.5 minutes (wrist-to-hip Freedson 3MET) and absolute percent differences ranging from 13.9%-24.5%. Group-level cross-validation to convert hip-to-wrist MVPA resulted in average absolute percent errors ranging from 3.1%-4.9%. Conversion of wrist-to-hip MVPA resulted in average absolute percent errors ranging from 3.0%-10.0%. We recommend the use of these equations to compare published estimates of MVPA between the wear-site cut-point combinations presented. 相似文献
