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

Widely varying recommended reading lists for psychiatry residents were obtained from 140 AMA-approved training programs. Approximately 4,000 articles, 2,800 books, and 200 serials were listed. The number of recommendations for each book was counted, and a rank-order determined. A second rank-order was determined from the lists of those eighty-seven programs which indicated that their material covered the "basic" literature; a third rank-order was determined from the number of residents using the lists. All rank-orders agreed on the "most recommended" book and the first eighteen books; there was a 92 percent correlation through the first 453 books. One-third of the "basic" recommendations were for the first 104 books; one-third for the next 349 books, and one-third for the remaining 1,994 books. The subject matter of the first 104 books indicated that the currently most popular subjects in psychiatry are psychoanalytic theories of personality, schizophrenia, psychotherapy, and child psychiatry. A list of the 104 most recommended books is appended. 相似文献

Designed-based research principles guided the study of 51 secondary-science teachers in the second year of a 3-year professional development project. The project entailed the creation of student-centered, inquiry-based, science, video games. A professional development model appropriate for infusing innovative technologies into standards-based curricula was employed to determine how science teacher’s attitudes and efficacy where impacted while designing science-based video games. The study’s mixed-method design ascertained teacher efficacy on five factors (General computer use, Science Learning, Inquiry Teaching and Learning, Synchronous chat/text, and Playing Video Games) related to technology and gaming using a web-based survey). Qualitative data in the form of online blog posts was gathered during the project to assist in the triangulation and assessment of teacher efficacy. Data analyses consisted of an Analysis of Variance and serial coding of teacher reflective responses. Results indicated participants who used computers daily have higher efficacy while using inquiry-based teaching methods and science teaching and learning. Additional emergent findings revealed possible motivating factors for efficacy. This professional development project was focused on inquiry as a pedagogical strategy, standard-based science learning as means to develop content knowledge, and creating video games as technological knowledge. The project was consistent with the Technological Pedagogical Content Knowledge (TPCK) framework where overlapping circles of the three components indicates development of an integrated understanding of the suggested relationships. Findings provide suggestions for development of standards-based science education software, its integration into the curriculum and, strategies for implementing technology into teaching practices. 相似文献

For typically developing (TD) children, the home literacy environment (HLE) impacts reading competence, yet few studies have explored the HLE of children with autism spectrum disorders (ASD). We collected information about the HLE of children aged 7–13 with ASD and their TD peers via a parental questionnaire and examined whether there were any differences in home literacy practices. Subtle group differences emerged. Children with ASD and concomitant language disorder (autism language disorder [ALD]) were engaged in shared reading and reading discussion more frequently than were TD children and children with ASD and age‐appropriate language skills (autism language normal [ALN]). However, both ALN and ALD children engaged in shared reading for a shorter duration than their TD peers. Across groups, frequency and duration of independent reading were positively associated with reading ability and attitude. Thus, home literacy practices appear to reflect child characteristics, and parents are well placed to facilitate their children's literacy development through encouragement and scaffolding.
Highlights
What is already known about this topic- The home literacy environment (HLE) impacts the reading development of typically developing children.
- Many children with autism spectrum disorders (ASD) have reading difficulties, but little is known about the HLE of children with ASD.
- We examined the relationship between the HLE and reading for children with ASD.
- Poorer readers with ASD were engaged in shared reading practices more frequently than proficient readers.
- Children with ASD engaged in shared reading practices for a shorter duration than their typically developing peers.
- Home literacy practices appear to reflect child characteristics.
- Parents are well placed to facilitate their children's literacy development through encouragement and scaffolding.

Community college students may experience more severe psychological concerns than traditional university students and have fewer institutional mental health resources available. This replication study examined the efficacy of three versions of a brief, structured web-based stress management program with community college students. The program focuses on improving perceptions of control over stressors, based on research suggesting that focusing on what you can control in the present (i.e., present control) is associated with less distress and better adjustment. Participants (N = 213 community college students) were randomly assigned to one of three conditions: present control intervention (PCI), PCI with enhanced stress logs (E-PCI) or PCI with mindfulness training (PCI + MF). They completed web-based, self-report measures at pre-intervention, post-intervention, and 3-week follow-up. Participants in all three intervention conditions demonstrated reductions in perceived stress and distress symptoms from pre-intervention to post-intervention and 3-week follow-up. In the PC+ MF group, the mean-within group effect size was d = ?0.46, which was slightly larger than the PCI group (d = ?0.36) and E-PCI group (d = ?0.41). This study replicated that present control interventions are effective in a community college sample. Community college students may benefit from web-based interventions designed to increase present control. 相似文献
