The Frontier of Web-based Instruction     

Coral Mitchell  Tony DiPetta  James Kerr 《Education and Information Technologies》2001,6(2):105-121

In spite of advances in course design software and experience with online offerings, the question of how web-based education affects teaching and learning remains largely unanswered, and the terrain of online learning remains largely unmapped. In this paper, through the stories of 10 faculties of education and one computer science instructor in Ontario, we map out a small piece of the frontier of web-based course delivery and plot a course for future exploration. We argue that most existing offerings take the form of a Lone Ranger or Greenhorn approach but that there is a need to move toward a strategic institutional Wagon Train approach that consolidates and integrates support for online teaching and learning. We argue, as well, that failures in online instruction cannot simply be attributed to improper instruction or inappropriate course design. Rather, at least part of the problem locates in the ways in which conversation is structured in the online environment.  相似文献   

When parents are deaf versus hard of hearing: patterns of sign use and school placement of deaf and hard-of-hearing children     

Mitchell RE  Karchmer MA 《Journal of deaf studies and deaf education》2004,9(2):133-152

This paper investigates the importance of knowing whether or not deaf and hard-of-hearing students have one or more deaf or hard-of-hearing parents. As noted by Mitchell and Karchmer (2004), deaf and hard-of-hearing school-age children and youth in the United States with at least one parent identified as "hearing impaired" are nearly evenly split between having at least one deaf parent and having at least one hard-of-hearing parent. However, there is no literature on the importance, if any, of this distinction. Findings from the investigation reported herein suggest that the distinction between having a deaf versus a hard-of-hearing parent is quite substantial, particularly as it pertains to the use of signing in the home. Further, signing in the home, which is reliably predicted by parental hearing status, is a significant predictor of the school setting in which the student is currently placed and the instructional use of signing in the classroom. Limitations related to the available measure of parental hearing status are discussed.  相似文献   

The role of law in protecting the child: A critique of the English system     

Jean Graham Hall  Barbara H. Mitchell 《Child abuse & neglect》1982,6(1):63-69

We have undertaken a critical appraisal of the current English system of law regulating: (1) Provision of services designed to prevent children coming into care of local authorities, which are the authorised agencies for dealing with children who are abused or neglected. (2) Ways of receiving children into care and also ways of terminating care orders. We question whether, and under what circumstances, care orders are really necessary. (3) Periodic reviews of children in care. We are critical of the English system and look to models in the USA as guides towards the possible reform of English law. We take the same perspective when considering termination of parental rights. In our opinion good laws do not of themselves provide the care and love which a child requires, but they make the caring possible by loved and loving adults. We argue that the law must provide the best possible framework to allow adequate caring by members of the non-legal professions, such as social workers and foster parents. At the same time the law must ensure that the rights of parents and children are protected.  相似文献

How confident are primary school teachers in teaching science?     

Mr. Stephen Yates  Dr. Denis Goodrum 《Research in Science Education》1990,20(1):300-305

The recent nationalDiscipline Review of Teacher Education in Mathematics and Science outlines the lack of confidence of many preservice primary school teachers in teaching science. This study explores the attitudes of 170 primary school teachers in a Perth school district. By means of a simple questionnaire the perceptions and attitudes of these teachers about the following aspects have been examined: (1) background understanding of science; (2) preservice training; (3) interest in teaching science; (4) skill in teaching science; (5) confidence in the plant, animal, matter, energy areas, and (6) time spent teaching science. Besides compiling frequency responses for all teachers on these aspects comparisons have also been made on the basis of: (1) gender; (2) time of graduation, and (3) grade level taught. Specializations: Primary science, teacher attitudes. Specializations: Primary science, science teaching strategies, curriculum implementation, cognitive studies.  相似文献   

Creativity Is About Being Free ...     

Cynthia A. Mitchell 《European Journal of Engineering Education》1998,23(1):23-34

I began this journey with the notion that creativity is somehow linked to having the freedom to explore and discover and dissemble and reassemble in whatever form we choose. This notion is compared with the ideas of researchers in the field of creativity. As an engineer who believes in a holistic approach, I am most comfortable with the idea of creativity as a multifarious beast, influenced by both personality and the cultural, social and professional environment in which engineers, in this case, find themselves. This being the case, engineering educators therefore have some opportunity to influence these factors, and hence the development of creative thinking in our students. I then examine a case study of a design project in second‐year chemical and environmental engineering in an attempt to ground these ideas about creativity in engineering education practice, and present the lessons learned from this experience.  相似文献

Associations between blocking,monitoring, and filtering software on the home computer and youth-reported unwanted exposure to sexual material online     

Michele L. Ybarra  David Finkelhor  Kimberly J. Mitchell  Janis Wolak 《Child abuse & neglect》2009,33(12):857-869

ObjectiveTo examine the relationship between the use of preventive software on the home computer and unwanted exposure to sexual material online.MethodsThe Youth Internet Safety Survey-2 was a national, RDD telephone survey conducted in March–June 2005. Eight hundred households (one caregiver and one child between the ages of 10 and 17 years) with home Internet access answered questions pertaining to Internet prevention activities in the household and adolescent behaviors and exposures online.ResultsUnwanted exposure to sexual material occurred in 32% of youth in homes with pop-up/spam blockers and 25% of youth in homes with filtering, blocking, or monitoring software on the home computer, compared to 43% of households without preventive software installed on the home computer. Among otherwise similar youth, pop-up/spam blockers installed on the home computer were significantly associated with 59% lower odds of reporting unwanted exposure to sexual material on the home computer; and filtering, blocking, or monitoring software was significantly associated with 65% lower odds. When data were stratified by youth sex, associations between preventive software and unwanted exposure were similar for boys and girls. When stratified by age, preventive software was associated with significantly reduced risk of unwanted exposure for 10–12-year olds and 13–15-year olds, but not for 16–17-year olds.ConclusionAlthough these correlational analyses are far from providing conclusive evidence that preventive software protects children from unwanted exposure to sexual material online, findings suggest that caregivers of boys and girls 15 years of age and younger who want to reduce the likelihood of unwanted exposure to sexual material on the home computer should consider including preventive software—especially filtering, blocking, or monitoring software—in their Internet safety plan.Practice implicationsPractitioners should partner with caregivers in developing an Internet safety plan, including proactive caregiver-youth discussions about expected Internet behavior appropriate for their household.  相似文献   

Situational interest impacts college students’physical activity in a design-based bike exergame     

Denis Pasco  Cédric Roure 《运动与健康科学(英文)》2022,11(2):172-178

Background:Active videogames or exergames have been used as an innovative way to promote physical activity(PA)among various populations.A player’s interest in active videogames is associated with the fun and entertaining nature of the games and may trigger situational interest,thus increasing engagement.The goal of this study was to examine the impact of situational interest dimensions on college students’PA when playing the design-based bike exergame Greedy Rabbit(Vescape,Berlin,Germany).Methods:Sixty undergraduate students(age:20.8±1.3 years,mean±SD,18-25 years old;51.7%males)were recruited from the kinesiology department of a university located in the southern region of Belgium.The participants were assigned to an experimental group(n=41)or a control group(n=19)based on an incremental cycling test.Students in the experimental group engaged in 1 session of Greedy Rabbit(Vescape)while students in the control group engaged in 1 session of a placebo version of Greedy Rabbit(Vescape).The length of the sessions ranged from 24 min to 31 min.Results:Results for the control group indicated that the players’PA metrics(cadence:F(19,360)=1.43,p=0.11;heart rate:F(19.360)=1.16,p=0.29;oxygen consumption:F(19,360)=0.83,p=0.67)were stable during the exergame.Results for the experimental group demonstrated the effects of time on the players’PA metrics and revealed significant associations between the change in the players’situational interest dimensions and PA metrics(cadence:F(19,800)=26.30,p<0.01;heart rate:F(19,800)=19.77,p<0.01;oxygen consumption:F(19,800)=10.04,p<0.01).Conclusion:An approach using a design-based exergame may be a relevant strategy for promoting levels of PA that yields positive health-related outcomes among college students.  相似文献   

The Relationship Between Teacher Behaviours and Student Talk in Promoting Quality Learning in Science Classrooms     

Ian Mitchell 《Research in Science Education》2010,40(2):171-186

This paper distils 24 years of classroom research into promoting quality learning in science classrooms to develop an overall framework for better understanding and describing both the learning and the teaching approaches that stimulate and support it. For me, quality learning is characterised by adjectives such as informed, purposeful, reflective, intellectually active, metacognitive and independent. Central to quality learning is the role of talk, and central to promoting talk which promotes quality learning are certain teacher behaviours. I first focus on the ways that teachers behave in the classroom in order to promote, react to and use student talk. These behaviours are summed up in a list of twelve principles for quality teaching. Each of these principles requires, as well as appropriate teacher behaviours, the use of effective teaching procedures. I then focus on four kinds of student talk that exemplify informed, purposeful, reflective and intellectually active thinking. These variously involve students’ existing ideas and explanations; increasing student ownership of practical activities; constructive challenges to the teacher (or text’s) idea, and lateral, reflective ‘thinking’ questions.  相似文献
