How Community College Faculty Members May Improve Student Learning Productivity in Their Online Courses     

Katrina A. Meyer 《Community College Journal of Research & Practice》2013,37(6):575-587

Eleven experienced community college faculty members were interviewed to elicit examples of how they improved student learning productivity in their online courses. The 11 faculty members represented eight different states, nine different fields or disciplines, and all were permanent or full-time faculty members at community colleges in the southern or western states. Based on a thematic analysis of the examples given, improvement in student learning occurred by (a) emphasizing seven approaches to increase student engagement, (b) using six different structuring tactics to focus student attention on learning, (c) using assessment techniques to improve learning, and (d) pursuing a personal passion for online teaching. These findings suggest that faculty can and do find ways to use different tools in different ways to improve student learning productivity in community colleges.  相似文献   

YouTube-based course orientation videos delivered prior to matriculation fail to alleviate medical student anxiety about anatomy     

Stefanie M. Attardi  Douglas J. Gould  Rebecca L. Pratt  Victoria A. Roach 《Anatomical sciences education》2022,15(4):685-697

Gross anatomy is a source of anxiety for matriculating medical students due to the large volume of information presented in a truncated timeline, and because it may be their first exposure to human cadavers. This study aimed to assess if video-based resources would affect matriculating medical students' anatomy state anxiety levels. Videos were designed to be short, YouTube-based units that served to provide orientation information about the anatomy course, dissection facilities, and available study resources to dispel anxiety around beginning their anatomy studies. To evaluate the impact of the videos, students in two consecutive matriculating years (2018 and 2019) completed the validated State-Trait Anxiety Inventory and a demographic questionnaire. The 2019 cohort (n = 118) served as the experimental group with access to the videos; while the 2018 cohort (n = 120) without video access served as a historical control. Analyses revealed that the groups were equivalent in terms of trait anxiety (P = 0.854) and anatomy state anxiety even when student video exposure was controlled (P = 0.495). Anatomy state anxiety was only significantly lower in students with prior formal anatomy exposure (P = 0.006). Further inquiry into students' prior anatomy experience identified that individuals with post-secondary dissection experience were significantly less anxious than those without formal anatomical experience (P = 0.023). These results may serve as a cautionary tale to educators; while preference for video-based instructional materials is prevalent in the literature, videos delivered on public social media platforms fail to prepare students for the psychological impact of studying human anatomy.  相似文献   

Comparing teacher roles in Denmark and England     

Peter Kelly  Hans Dorf  Nick Pratt  Ulrike Hohmann 《Compare》2014,44(4):566-586

This article reports the findings of a comparative study of teaching in Denmark and England. Its broader aim is to help develop an approach for comparing pedagogy. Lesson observations and interviews identified the range of goals towards which teachers in each country worked and the actions these prompted. These were clustered using the lens of Bernstein’s pedagogic discourse to construct teacher roles, which provided a view of pedagogy. Through this approach we have begun to identify variations in pedagogy across two countries. All teachers in this study adopted a variety of roles. Of significance was the ease with which competent English teachers moved between roles. The English teachers observed adopted roles consistent with a wider techno-rationalist discourse. There was a greater subject emphasis by Danish teachers, whose work was set predominantly within a democratic humanist discourse, whilst the English teachers placed a greater emphasis on applied skills.  相似文献   

Validity and Reliability of Proximity Detection with Bluetooth-Enabled Accelerometers among Adults     

Deirdre Dlugonski  Aaron P. Wood  Katrina D. DuBose  Patrick Rider  Alexander M. Schoemann 《Measurement in physical education and exercise science》2013,17(3):272-279

ABSTRACT

Introduction: This study examined the concurrent validity and inter-pair reliability of the proximity detection function on Bluetooth-enabled accelerometers across manufacturer-specified ranges. If valid, this method could be used for objectively measuring shared physical activity participation. Method: Thirty-six dyads aged 21.6 (2.1) years wore two sets of Bluetooth-enabled accelerometers initialized as beacons and receivers to compare accelerometer-measured proximity detection to direct observation under 11 different controlled and free-living conditions. Results: The proportion of minutes in which proximity was detected differed across conditions (p < .001), with the highest proportions in the controlled conditions (.77–1.0). Among the free-living conditions, the different room (.73 ± .20) condition had the highest proximity detection proportions. There were no differences in the proximity detection across accelerometer pairs (p = .265). Conclusion: Proximity detection with Bluetooth-enabled accelerometers was reliable and had the highest detection rates under the controlled treadmill walking conditions. Despite limitations, using Bluetooth-enabled accelerometers is a promising approach for measuring shared physical activity.  相似文献   

Tibial shock measured during the fencing lunge: the influence of footwear     

Jonathan Sinclair  Katrina Taylor  Andrew Greenhalgh 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(2):65-71

Fencing is a high-intensity sport involving dynamic movements such as the lunge exposing the musculoskeletal system to high impact forces, which emphasises the importance of the shock attenuating properties of footwear as a factor in the prevention of injury. The aim of this study was to investigate the magnitudes of the transient axial impact shock experienced at the tibia between traditional fencing shoes and standard athletic footwear during the impact phase of the fencing lunge. Peak tibial shock was measured in 19 male fencers in 4 different footwear conditions using an accelerometer placed on the distal aspect of the tibia. The standard footwear (11.08 g and 8.75 g for squash and running shoe, respectively) resulted in significant (p < 0.01) reductions in peak impact shock in comparison to the traditional fencing shoes (15.93 g and 13.97 g for the Adidas and Hi-Tec shoe, respectively). No significant differences were found between the running and squash shoes (p = 0.09) or between the fencing shoes (p = 0.48). The documented reduction in impact shock found suggests that running or squash specific footwear may reduce overuse injury occurrence, indicating that there is justification for a re-design of fencing shoes.  相似文献   

Physical Therapists’ Perceptions of Knowledge and Clinical Behavior Regarding Cardiovascular Disease Prevention     

R Scott Van Zant  Kelly Jo Cape  Katrina Roach  Janie Sweeney 《Cardiopulmonary Physical Therapy Journal》2013,24(2):18-26

Purpose

The study purpose was to assess perceptions of physical therapists (PTs) regarding the role of physical therapy in cardiovascular disease (CVD) prevention.

Methods

A 25-item survey, validated by expert cardiovascular/pulmonary (CVP) PTs, was sent electronically to 2,673 PTs. Each item represented an element of clinical practice behavior: education of CVD/risk factors (EDCVD), administration of primary CVD prevention (PRECVD), identifying underlying CVD/risk factors (IDCVD), monitoring CV status in patients with CVD (MONCVD). Responses were assigned numeric values (strongly agree = 5 to strongly disagree = 1), and mean element scores were analyzed.

Results

Most of the 516 respondents were APTA Section members (34% CVP Section, 42% other Section membership) and worked in academia (53%). Items showing a high (> 95%) level of agreement included patient education of smoking (97%) and monitoring exercise intensity (99%), assessing exercise benefits (99%), clinically identifying obesity (97%) and hypertension (97%), and monitoring CV response to exercise (99%). Items failing to reach 80% overall agreement were patient education of CVD medications (79%) and blood chemistry (72%), and assessing CVD family history (75%), patient BMI (60%), and body composition (33%). Identifying underlying CVD (77.2%) was the only practice behavior failing to reach 80% agreement. Outpatient PTs agreed significantly less to all elements vs. academics, and to IDCVD vs. all PTs except home health.

Conclusions

Physical therapists support most CVD prevention behaviors, but not given elements of patient education and identifying underlying CVD/risk factors.Key Words: cardiovascular disease, primary disease prevention, secondary disease prevention  相似文献   

An analysis of predictors of college students' ethical inclinations     

Cornelius B. Pratt  Gerald W. McLaughlin 《Research in higher education》1989,30(2):195-219

Correlational and path analyses are used to examine the effects of four situations on self-reported ethical behaviors on four primary ethical dimensions among 323 undergraduate communication students in two mid-Atlantic public universities. The four situations are: the students' self-reported ethical beliefs, the students' perceptions of their professors' ethical beliefs, and the students' perceptions of both the beliefs and behaviors of their peers. The ethical dimensions, which form the basis for path models, are direct-testing, indirect-testing, indirect-substitution, and direct-substitution behaviors. Results indicate that different path models fit different types of behaviors. For example, professors' beliefs, as perceived by the students, have an indirect effect on students' behaviors, particularly in the indirect dimensions. Also, in three dimensions, interactions among professors' beliefs and most college students' beliefs and behaviors influence students' behaviors. An interpretation of these behaviors is suggested, based on an adaptation of the Ajzen and Fishbein theory of reasoned action.  相似文献   

Looking for inhibition of return in pigeons     

Gibson BM  Juricevic I  Shettleworth SJ  Pratt J  Klein RM 《Learning & behavior》2005,33(3):296-308

We conducted four experiments in order to investigate whether pigeons' responses to a recently attended (i.e., recently pecked) location are inhibited. In Experiments 1 and 2, stimulus displays were similar to those used in studies of inhibition of return (IOR) with humans; responses to cued targets tended to be facilitated rather than inhibited. In Experiments 3 and 4, birds were presented with stimulus displays that mimicked clusters of small grains and were relatively localized, which should have been more appropriate for detecting IOR in pigeons. The results from these experiments again provided evidence for facilitation of responding to cued targets, rather than for IOR.  相似文献   

A cybernetic model for curriculum development     

David Pratt 《Instructional Science》1982,11(1):1-12

The task of the curriculum developer is to design instructional systems which will produce consistently high levels of learning despite wide variation in pupil characteristics. This can be viewed as a cybernetic question of regulating variety in a system to produce stable and high level output. Six cybernetic principles—goal orientation, limitation of input, monitoring, control decisions, restoration of equilibrium, and positive feedback—are described, and their application to curriculum discussed. It is concluded that a cybernetic model can guide curriculum developers in designing effective learning systems.  相似文献   

The role of feedback from phonology to orthography in orthographic learning: an extension of item‐based accounts     

Meredith McKague  Chris Davis  Chris Pratt  Michael B. Johnston 《Journal of Research in Reading》2008,31(1):55-76

Skilled readers were trained to recognise either the oral (n=44) or visual form (n=40) of a set of 32 novel words (oral and visual instantiation, respectively). Training involved learning the ‘meanings’ for the instantiated words and was followed by a visual lexical decision task in which the instantiated words were mixed with real English words and untrained pseudowords, and the instantiated words were to be considered as words. The phonology‐to‐orthography consistency (feedback consistency) of the instantiated words was manipulated to investigate the role of feedback from phonology in orthographic learning. Masked consonant and vowel‐preserving form primes were used in the lexical decision task as probes of orthographic learning. Feedback‐consistent instantiated words were recognised significantly faster in lexical decision than feedback‐inconsistent instantiated words, and facilitation was significantly greater from consonant‐preserving than vowel‐preserving primes for orally but not visually instantiated words. The results support the hypothesis that orthographic representations based on a consonant frame can be generated from the speech signal before encountering the printed forms, and that feedback from phonology is involved in the early stages of orthographic learning.  相似文献
