How day of posting affects level of critical discourse in asynchronous discussions and computer-supported collaborative argumentation     

Allan Jeong  Sue Frazier 《British journal of educational technology : journal of the Council for Educational Technology》2008,39(5):875-887

In asynchronous threaded discussions, messages posted near the end of the week provide less time for students to critically examine and respond to ideas presented in the messages than messages posted early in the week. This study examined how the day in which messages are posted (early, midweek and weekend) in computer-supported collaborative argumentation affect the number of responses elicited by arguments and challenges, and how its effects differ across the four types of exchanges (argument–challenge, challenge–counterchallenge, challenge–explain, challenge–evidence) that serve as indicators of critical discourse. This study found that the day of posting had a significant effect on the number of responses elicited per message, with the greatest to smallest effect on argument–challenge, challenge–counterchallenge, challenge–explain and challenge–evidence exchanges respectively. These findings highlight some of the limitations of asynchronous discussions, and suggest alternative ways to implement and design discussion environments to promote higher levels of critical discourse.  相似文献   

Teacher education programmes delivered at a distance: An examination of distance student perceptions     

Allan Young  Chance W. Lewis 《Teaching and Teacher Education》2008

Recent technological developments have greatly influenced the ways American universities deliver educational course offerings to students at a distance. The perception of pre-service teachers in distance education programmes is germane to the planning and delivery of distance education courses in teacher education departments in the future. The results of this American study revealed a differing perception between male and female students in the area of course structure, student/teacher interaction, overall course satisfaction and peer interaction. As a result of this study, recommendations are provided for teacher preparation programmes to improve distance education course offerings for prospective teachers in the USA and implications for educators involved in teacher preparation internationally.  相似文献

A sequential analysis of responses in online debates to postings of students exhibiting high versus low grammar and spelling errors     

Allan Jeong  Haiying Li  Andy Jiaren Pan 《Educational technology research and development : ETR & D》2017,65(5):1175-1194

Given that grammatical and spelling errors have been found to influence perceived competence and credibility in written communication, this study examined how a student’s grammar and spelling errors affect how other students respond to the student’s postings in four online debates hosted in asynchronous threaded discussions. Message-response exchanges were sequentially analyzed to identify patterns in students’ replies to arguments and challenges with counter-challenges, explanations, and evidentiary support posted by students that exhibited low versus high number of grammatical and spelling errors. Although no causal inferences can be drawn from this study, the findings nevertheless suggests that: (a) arguments posted by high-error students are more likely to be challenged than arguments posted by low-error students; (b) exchanges between high-error students can amplify the effects of grammar/spelling errors; and (c) higher levels of argumentation can be achieved by placing students into groups that are heterogeneous in writing skills in general. The findings and methods used in this study lay the groundwork for further research on strategies for managing individual differences in students’ grammar and spelling (and other student behaviors in general) and increasing the level of critical discourse in online discussions.  相似文献   

Children in care or in need: educational progress at home and in care     

Ian Sinclair  Nikki Luke  David Berridge 《牛津教育评论》2019,45(4):443-460

ABSTRACT

By age 16 the attainment of most children in or on the edge of out of home care has fallen well behind the average for their age. This paper uses the English National Pupil Database to examine how much of this falling behind occurs before the age of seven, and how any subsequent decline relates to time in care as against time outside it. We compare the previous progress of three groups of 16-year-olds: 5175 looked after by the state (CLA), 17,392 in need but not in care (CIN), and 22,567 children matched with the CLA or CIN on initial attainment, special educational needs, and eligibility for free school meals. We found that the attainment of the CIN and those CLA not yet in care was around one standard deviation below the cohort average at age seven. It then fell relative to their peers while their rate of unauthorised absences and exclusions grew. Removal from home to care appeared to halt or greatly reduce this decline but did not, on average, reverse it. We conclude that educational interventions for CLA should also include CIN, start before seven, target both school and family, and exploit the educational opportunity which care provides.  相似文献

The Effects of Gender Interaction Patterns on Student Participation in Computer-Supported Collaborative Argumentation   总被引：2，自引：0，他引：2  

Allan Jeong  Gayle V. Davidson-Shivers 《Educational technology research and development : ETR & D》2006,54(6):543-568

In this study we examined response patterns in exchanges between males and females and their effects on gender participation in five online debates. Students classified messages into arguments, evidence, critiques, and elaborations while posting messages to the debates to facilitate argumentation and the sequential analysis of message-response sequences. The findings revealed no differences in number of critiques posted in response to arguments because females were just as likely as males to critique messages from both males and females, and because females responded to males with critiques at a higher than expected frequency. Posthoc analysis revealed strong indications that females posted fewer rebuttals to the critiques of females than males, and males posted more rebuttals to the critiques of females than females. The methods used in this study illustrate a process-oriented approach to explain and predict gender differences in participation and serve as a framework for future research on gender participation, group interaction, and strategies for facilitating collaborative argumentation and problem solving.  相似文献   

Sharing Roles and Responsibilities in Initial Teacher Training: Perceptions of some key players     

Anne Williams  Allan Soares 《Cambridge Journal of Education》2002,32(1):91-107

This paper examines perceptions of roles and responsibilities in primary and secondary initial teacher education following a sustained period of increase in the involvement of schools. The paper reports findings from a survey of higher education staff, school-based mentors and student teachers, which sought information about their perceptions of roles and responsibilities. A postal survey was followed up by telephone interviews. We found broad levels of agreement between all three partners in the training process and across primary and secondary phases. We found no evidence of a wish on the part of schools to assume greater responsibility for training student teachers. All three parties involved in the survey were able to articulate clearly areas of student professional development where they see complementary roles for school and higher education.  相似文献   

Exploring the use of multiple analogical models when teaching and learning chemical equilibrium     

Allan G. Harrison  Onno De Jong 《科学教学研究杂志》2005,42(10):1135-1159

This study describes the multiple analogical models used to introduce and teach Grade 12 chemical equilibrium. We examine the teacher's reasons for using models, explain each model's development during the lessons, and analyze the understandings students derived from the models. A case study approach was used and the data were drawn from the observation of three consecutive Grade 12 lessons on chemical equilibrium, pre‐ and post‐lesson interviews, and delayed student interviews. The key analogical models used in teaching were: the “school dance”; the “sugar in a teacup”; the “pot of curry”; and the “busy highway.” The lesson and interview data were subject to multiple, independent analyses and yielded the following outcomes: The teacher planned to use the students' prior knowledge wherever possible and he responded to student questions with stories and extended and enriched analogies. He planned to discuss where each analogy broke down but did not. The students enjoyed the teaching but built variable mental models of equilibrium and some of their analogical mappings were unreliable. A female student disliked masculine analogies, other students tended to see elements of the multiple models in isolation, and some did not recognize all the analogical mappings embedded in the teaching plan. Most students learned that equilibrium reactions are dynamic, occur in closed systems, and the forward and reverse reactions are balanced. We recommend the use of multiple analogies like these and insist that teachers always show where the analogy breaks down and carefully negotiate the conceptual outcomes. © 2005 Wiley Periodicals, Inc.
