AN INVESTIGATION OF THE ACCEPTABILITY OF VIDEOCONFERENCING WITHIN A SCHOOL‐BASED BEHAVIORAL CONSULTATION FRAMEWORK

School‐based behavioral consultation with classroom teachers is one of the primary ways school psychologists deliver intervention services to students. The present study aimed to evaluate the acceptability of videoconferencing (VC) with teachers as an alternative medium of consultative communication. Specifically, problem identification interviews (PIIs) were conducted with 60 classroom teachers to simulate a typical consultation interaction. Each teacher completed two PIIs with the researcher consultants, one in a traditional face‐to‐face (FtF) format and one in a videoconference (VC) format Teachers completed two brief pre‐post measures, the Fast Form of the Technology Acceptability Model (FF‐TAM) and the Distance Communication Comfort Scale (DCCS) to evaluate the acceptability of VC. Demographic moderators of the acceptability of VC were evaluated using a multiple regression analysis. The results suggest that although teachers rated VC as an acceptable communication medium prior to participating in the VC interview, teacher acceptability ratings increased to “highly acceptable” after participating in the study. Finally, no variables were identified that significantly moderated the relationship between teachers' acceptability rating of VC and their demographic variables. Implications for practice and future research are discussed.  相似文献   

A study of culturally syntonic variables in the bilingual/bicultural science classroom     

Robertta H. Barba 《科学教学研究杂志》1993,30(9):1053-1071

The purpose of this study was to conduct a needs assessment of bilingual/bicultural elementary science classrooms in order to determine if the current instructional environment addresses the educational needs of Hispanic/Latino children. This study examined 57 randomly selected elementary bilingual/bicultural science classrooms in a large metropolitan area of the southwestern United States in terms of culturally syntonic variables (i.e., culture-of-origin beliefs and/or practices that impact the teaching/learning process). Findings from this study indicate that Hispanic/Latino children are receiving science instruction: (a) with culturally asyntonic printed materials, teaching strategies, and supplementary materials, (b) in classrooms that do not use the child's native language, familia learning groups, peer tutoring, or manipulative materials, and (c) with oral and verbal instruction that lack culturally syntonic role models, examples, analogies, and elaborations. Findings from this study imply that changes are needed in pre-service and in-service teacher training, in science textbook formats, and in the scope and focus of elementary school bilingual/bicultural science curriculum and instructional strategies.  相似文献

Observational learning of discriminative avoidance in hooded rats     

Del Russo  Jon Evan 《Learning & behavior》1975,3(1):76-80

To determine the aspects of an observational situation facilitating subsequent acquisition of an observed task, two experimental groups of rats were exposed to a model’s performance of a two-way discriminative shuttlebox avoidance task with a tone as the discriminative stimulus. One experimental group (OND) observed the performance of a naive demonstrator; the other experimental group (OSD) observed a skilled demonstrator. A stimulus control group (SC) was exposed to the tone with no model present; a response control group (RC) observed demonstrator running with no tone present. A naive control group (NC) received no observational experience. All groups were subsequently tested on acquisition of the task. An analysis of variance on avoidance scores and Newman-Keuls tests for differences between means revealed that OND and OSD groups performed significantly more avoidances than the control groups. Exposure to the total tone-running sequence was found to be necessary for observational learning. The results were interpreted in terms of a sensory-sensory conditioning model.

Institutional repositories: is the open access door half open or half shut?     

Evan Harris MP 《Learned Publishing》2005,18(2):85-89

The response of the UK Government to the Report on science publishing by the Science and Technology Select Committee of the House of Commons is criticized for failing to take the necessary action to research or help catalyse a change in the publishing model. The initiatives of the National Institutes of Health and the Wellcome Foundation in setting up central archives are examined and their utility questioned. The evidence base for a change to open access is explored.  相似文献

Perceptual decision making for baseball pitch recognition: using P300 latency and amplitude to index attentional processing     

Radlo SJ  Janelle CM  Barba DA  Frehlich SG 《Research quarterly for exercise and sport》2001,72(1):22-31

This study was designed to examine the perceptual and attentional processes associated with the effects of administering a cost-benefit precuing paradigm to intermediate and advance-level baseball batters. Psychophysiological and performance data obtained from 10 advanced and 10 intermediate-level players were compared. A total of 400 pitches (200 fastballs, 200 curveballs) was randomly presented via a large projection screen, and participants pressed one of two buttons to indicate the type of pitch thrown. Verbal precues were given for 300 of the pitches. Of those, 75% were valid, and 25% were invalid. Electroencephalographic data collected from the P location was used to assess the latency and amplitude of P300. Analysis of variance (Skill Level x Precue x Pitch) for P300 and reaction time (RT) indicated that intermediate batters produced shorter P300 latencies, larger P300 amplitudes, longer RTs, and less correct responses than the advanced batters; the effects were more pronounced for the curveballs. These results suggest that intermediate batters are less efficient in their perceptual decision-making processes due to greater limitations in attentional capacity when compared with advanced batters.  相似文献   

Leg soft tissue position and velocity data from skin markers can be obtained with good to acceptable reliability following heel impacts     

Evan A. Brydges  Timothy A. Burkhart  William J. Altenhof 《Journal of sports sciences》2015,33(15):1606-1613

Quantifying soft tissue motion following impact is important in human motion analysis as soft tissues attenuate potentially injurious forces resulting from activities such as running and jumping. This study determined the reliability of leg soft tissue position and velocity following heel impacts. A grid of black dots was applied to the skin of the right leg and foot (n = 20). Dots were automatically detected (ProAnalyst^®) from high-speed records of pendulum and drop impacts. Three trained measurers selected columns of dots on each participant for analysis; one measurer 6 months later. Between- and within-measurer differences in kinematic variables were all relatively small (<0.8 cm for position; <3.7 cm/s for velocity) between-measurers and (<0.5 cm for position; <2.6 cm/s for velocity) within-measurer. Good (coefficients of variation (CV) ≤ 10%) to acceptable (CV > 10% and ≤20%) reliability was shown for 95% of the position measures, with mean CVs of 10% and 11% within-measurers and between-measures, respectively. Velocity measures were less reliable; 40% of the measures showed good to marginal (CV > 20% and ≤30%) reliability. This study established that leg soft tissue position data from skin markers could be obtained with good to acceptable reliability following heel impacts. Velocity data were less reliable but still acceptable in many cases.  相似文献
