Integrating technology in a field-based teacher training program: The PT3@ASU project

The Preparing Tomorrow’s Teachers to Use Technology (PT3) initiative has funded various efforts to improve and enhance the technology preparation of preservice teachers. At Arizona State University, these efforts have focused on providing preservice teachers with opportunities to develop, implement, and evaluate their own instructional activities that utilize technology effectively and appropriately in authentic situations, to give them the myriad of tools necessary to integrate technology into teaching and learning activities. This paper focuses on the integration of these efforts into the field-based elementary education program, and discusses our formative evaluation of the field-based technology integration model, through the following questions: What are the preliminary successes of the model with regard to student perceptions, attitudes, and integration of technology into instructional activities? and What components of the model require additions or modifications?     

Simultaneous processing of visual and spatial stimuli in pigeons

Pigeons were trained to symbolically match comparison stimuli to either visual sample stimuli presented on a center key or to spatial sample stimuli presented on side keys. Tests were carried out in which visual and spatial cues were simultaneously presented in compound and short-term memory was probed for either visual or spatial information. Symmetrical interference with the matching of visual and spatial components of compounds was found when the visual and spatial cues were presented on separate keys. However, when visual and spatial cues were superimposed on the same side key, no interference was observed relative to element control tests. Discussion of these findings focuses on accounts in terms of limited processing capacity, coding decrement, and receptor orientation mechanisms.     

First-generation students' academic engagement and retention

This study investigates differences in academic engagement and retention between first-generation and non-first-generation undergraduate students. Utilizing the Student Experience in the Research University survey of 1864 first-year students at a large, public research university located in the United States, this study finds that first-generation students have lower academic engagement (as measured by the frequency with which students interacted with faculty, contributed to class discussions, brought up ideas from different courses during class discussions, and asked insightful questions in class) and lower retention as compared to non-first-generation students. Recommendations that higher education faculty can follow to promote the academic engagement and retention of first-generation students are addressed.     

Supporting the free market: Information technology policy in Hong Kong

Economic policy in Hong Kong is frequently cited as a shining example of the laissez‐faire model for development, with minimal government intervention. However, the government has played a bigger role in the economy than is often recognized, responding to market failures, social problems, and the needs of the business community. Information technology (IT) policy in Hong Kong has mirrored the colony's laissez‐faire economic strategy, with little government effort to promote the production or use of IT products and services. Hong Kong has become an advanced user of IT in several economic sectors and an assembly site for personal computer hardware. However, like much of the manufacturing sector, the computer industry is moving much of its production to China, causing concern about the future of Hong Kong's economy. While some people feel that Hong Kong can flourish as a financial and business services center, others feel that this role will be diminished as the Chinese economy liberalizes and other centers develop in mainland China. They argue that Hong Kong needs to upgrade its technological capabilities and develop technology‐intensive activities such as R&D and software development to complement China's manufacturing activities. The government has begun to respond with limited measures to encourage R&D, train more scientists, engineers, and managers, and support technology start‐ups. Hong Kong has the potential to develop software and information services industries to serve the Chinese market. It also can apply IT to other sectors to maintain its leadership as a financial, business services, transportation, and communications center.     

Comment on a Preliminary Comparison of Front and Back Squat Exercises (Russell & Phillips, 1989)

Abstract

Perception of affordances research in children with developmental disabilities has only examined well practiced skills. Ten toddlers with Down syndrome and 10 with typical development walked across a GAITRite mat, with and without an obstacle. We coded the toddlers' behaviors after 1 and 3 months of walking experience when they encountered the obstacle (avoid, crawl, error, and walk successfully) and calculated gait parameters (step length, width, and velocity). Both groups actively explored their affordances. Despite similar decreases in step length and velocity when approaching the obstacle, toddlers with Down syndrome were more likely to select successful but conservative crawling strategies that minimized balance requirements and reduced risk of falling. Group differences were due to risk management rather than difficulty perceiving affordances.     

Epistemic Perspective and Online Epistemic Processing of Evidence: Developmental and Domain Differences

Relations between epistemic perspective and online epistemic processing of evidence when reading a text were examined. Thirty-seven young adolescents and 24 graduate university students were asked to read and think aloud with two texts, one in the history domain and the other in the science domain. Participants also completed a prior-knowledge test and an instrument assessing their epistemic perspective. Results showed that participants who exhibited an evaluativist epistemic perspective and high prior knowledge used the epistemic standard of scientific research more than participants who held a nonevaluativist epistemic perspective. Furthermore, an age-related developmental difference was observed, with adults using the epistemic standard of scientific research more than young adolescents. Domain differences were observed in both participants’ epistemic perspectives and online epistemic processing. Participants overall engaged in online epistemic processing of evidence more in the history topic than in the science topic.     

Application and Reliability of the Retrospective Interview Procedure to Trace Physical Activity Patterns in Master Athletes and Nonactive Older Adults

This paper reports the results of two studies. The purpose of the first study was to determine if lifestyle variables and past involvement in physical activity was related to current activity levels in master athletes and sedentary older adults. Retrospective interviews were conducted with 12 master athletes and 12 sedentary older adults. Results demonstrated that education level, spouse participation, smoking, and recent physical activity levels were indicators of current involvement. The second study investigated the reliability of the data collected in the retrospective interviews. Similar to results with younger samples, we confirm that lifestyle variables and physical activity involvement could be accurately recalled for a period of 25 years, making this tool a useful addition for the study of physical activity in older adults.     

The use of evidence-based instructional strategies in special education settings in secondary schools: Development,implementation and outcomes

The lack of effective training and an inability to maintain fidelity are two major barriers to implementing evidence-based practices in schools. This study examined the level of implementation of evidence-based practices by teachers after they participated in a unique training program aimed at enhancing the use of evidence-based practices. The results indicate that five months posttraining, 62% of the evidence-based strategies had been implemented and these levels were maintained 13-months posttraining. While the level of exposure to students of the evidence-based practices was low, significant longitudinal improvements in reading and levels of inclusion were documented.     

Anthropometric characteristics as discriminators of body-building success.

A total of 36 non-elite male body builders were observed at the time of competition. Their mean physical characteristics (+/- S.D.) were: age, 24.6 +/- 4.8 years; height, 174.4 +/- 6.7 cm; bodyweight, 80.3 +/- 11.0 kg. Their body composition values were: percentage body fat, 9.3 +/- 1.6%; fat-free mass, 72.8 +/- 9.8 kg. The mean somatotype for all subjects was: endomorphy, 2.3 +/- 0.6; mesomorphy, 6.2 +/- 0.9; ectomorphy, 1.2 +/- 0.6. The body proportions (cm) included: biacromial diameter/bi-iliac diameter, 1.463 +/- 0.132; torso length/height, 0.468 +/- 0.018; chest circumference/abdominal circumference, 1.345 +/- 0.059. The body builders in the present study were younger, had lower bodyweights, lower fat-free mass, lower mesomorphy ratings, smaller circumferences, and smaller skeletal dimensions than elite body builders reported in the scientific literature. When the body builders in the present study were divided into successful and unsuccessful groups based on actual competition results, a multiple-discriminant analysis found that biacromial diameter/bi-iliac diameter, torso length/height, chest circumference/abdominal circumference, percentage body fat, height, and bodyweight accounted for 80.6% of the explained variance. These data indicate that the success of a body builder can be accounted for in large part by easily obtained physical variables.
