动画教学代理对多媒体学习的影响:学习者经验与偏好的调节作用

以往研究发现,动画教学代理对多媒体学习效果的影响不一致,可能受到学习者特征和偏好的调节。本研究以“空调的组成部分及工作原理”为实验材料,采用两个实验控制教学代理有无、经验高低和代理偏好,探讨动画教学代理对多媒体学习的影响。实验1发现与无代理组相比,代理组对教学视频的注视点个数更多,平均眼跳潜伏期更短,学习兴趣也更高;低经验者在代理条件下的迁移成绩更好。实验2发现学习者在偏好代理和非偏好代理条件下的迁移成绩好于无代理组;偏好代理组感知到更低的认知负荷,对总体视频的注视点个数和注视频率更多,平均眼跳潜伏期更短,对学习内容的注视点个数更多。结论认为：在多媒体中加入教学代理不会减少学习者对学习内容的注意,能提高多媒体学习效果,支持社会代理理论假设;教学代理能提高低经验者的学习效果,但对高知识经验者无明显作用;加入学习者偏好的代理形象会促进学习,但加入学习者非偏好的代理形象并没有阻碍学习。     

Work-integrated practices in a technology education setting

This study sought to explore emerging university-industry partnerships in technology transfer education, the process for the engagement, and benefits to the learning and teaching experience. Participants were a convenience sample of ten lecturers at a technology university (females = 80%; management sciences = 70%). Data on the scope and nature of industry partnership practices and experiences were collected using semi-structured interview. Thematic data analysis revealed the lecturers to perceive benefits to learning and teaching from the university-industry engagement, including the use of field practice examples, customer service-orientated skills, innovation learning and technology transfer, curriculum enhancement and professional learning. A work-integrated approach to learning appears to be a serviceable model for real-world technology transfer education outcomes.     

Relations Between Instructional Practices and On-Task Behavior in Classrooms Serving American Indian Students

Achievement disparities between American Indian students and non-American Indian peers are persistent and well documented. Student engagement is a promising target for intervention given its relation to academic achievement. This study investigated the relation between specific teacher practices (opportunities to respond [OTRs], praise, and reprimands) and classroom on-task behavior in an urban, public K–8 school that serves primarily American Indian students. OTRs and praise were positively associated with student on-task behavior, whereas reprimands were negatively associated with on-task behavior. Results from multilevel logistic regression indicated that OTRs significantly increased the likelihood that a classroom was highly on-task, whereas the reprimands significantly decreased the likelihood. Praise did not have a significant effect after controlling for the other variables in the model. Results are interpreted in a context of evidence-based instructional practices for increasing OTRs and praise, decreasing reprimands, and ultimately enhancing on-task behavior in an urban classrooms serving primarily American Indian youth.     

Personal value preferences,group identifications,and cultural practices of Palestinian Israelis working in close contact with Jewish Israelis

The present study investigates the connection between personal value preferences, group identifications, and cultural practices among Palestinian Israelis working in close contact with the Jewish population in Israel. One hundred twenty-two Palestinian Israelis participated in the study. The participants were employed in different professional positions in the Tel Aviv Metropolitan area and were recruited to the study using the snowball technique. A stronger national identification was associated with a higher preference for the security and conformity values, and a lower preference for the humility values. A stronger ethnic identification was associated with a lower preference for the security, power, and stimulation values. Group identifications mediated the connection between personal value preferences and cultural practices. A longer time working in close contact with the majority group and less frequent visits home were associated with a greater adherence to the majority group’s cultural practices but not with adherence to the ethnic group’s practices and not with the group identifications.     

Hand Gesture and Mathematics Learning: Lessons From an Avatar

A beneficial effect of gesture on learning has been demonstrated in multiple domains, including mathematics, science, and foreign language vocabulary. However, because gesture is known to co‐vary with other non‐verbal behaviors, including eye gaze and prosody along with face, lip, and body movements, it is possible the beneficial effect of gesture is instead attributable to these other behaviors. We used a computer‐generated animated pedagogical agent to control both verbal and non‐verbal behavior. Children viewed lessons on mathematical equivalence in which an avatar either gestured or did not gesture, while eye gaze, head position, and lip movements remained identical across gesture conditions. Children who observed the gesturing avatar learned more, and they solved problems more quickly. Moreover, those children who learned were more likely to transfer and generalize their knowledge. These findings provide converging evidence that gesture facilitates math learning, and they reveal the potential for using technology to study non‐verbal behavior in controlled experiments.     

Confidentiality, privacy, and the facilitating role of psychoanalytic organizations

Burgeoning external threats to confidentiality by claims to clinical information create unprecedented challenges for psychoanalysts. Internal threats arise from the use of clinical material for educational, scientific and historical purposes. Traditionally, confidentiality is considered a patient's right and an analyst's obligation; privacy is not usually stated as a professional requirement. Little consideration has been given to the impact of the confidentiality and privacy dilemmas that analysts encounter throughout their careers. There has been no systematic examination of the confidentiality policies of psychoanalytic organizations, nor has their role in facilitating maintenance of patient confidentiality and analysts' privacy been made explicit. The research reported here was undertaken to address these issues and to obtain baseline information about the current confidentiality policies and practices of psychoanalytic organizations in three English-speaking countries (Britain, Canada and the USA). The author discusses survey results in the light of the challenges which arise at each phase of the analytic career. She makes suggestions as to how psychoanalytic organizations can and should facilitate analysts' resolutions of contemporary confidentiality and privacy dilemmas.     

Studying the Practice of Cooperation and Collaboration Within an International Research Project on the Everyday Lives of Families

The aim of this paper is to analyse the sociocultural dynamics underlying collaborative research. The article is based on an international collaborative project on the everyday lives of working families in Italy, Sweden and the USA. The aim of this paper is to show that collaborative research does not necessarily produce collaboration: this is possible only with very strong rules between partners. It proposes a distinction between collaboration and cooperation, and uses this distinction to examine intergroup and intragroup joint activity. Through the analysis of the communicative exchanges occurring between researchers, the paper highlights conditions in which cooperation can become fruitful collaboration.

Triangulating School Climate: Areas of Convergence and Divergence Across Multiple Levels and Perspectives

Students often have differing perceptions of their school's climate. Although these subjective perceptions can be meaningful outcome predictors, discrepancies create challenges for those seeking to globally characterize or intervene to improve the climate of a school. Trained, independent  observers can provide insights on perceptible and ostensibly malleable aspects of the school; however, the extent to which these observations help us to understand differences in students’ report of school climate has not been examined. To study this, we assessed convergence and divergence between independent observers’ assessments and students’ perceptions of school climate at the classroom and school levels. Data come from the Maryland Safe and Supportive Schools Initiative (MDS3), which included 20,647 students and observations of 303 teachers in 50 high schools. Students responded to survey items regarding safety, engagement, and environment; independent observers assessed teachers’ classroom practices and the school physical environment. A three-level model partitioned variance to the individual, classroom, and school levels. The variance in students’ climate perceptions was primarily between students, with most classroom and school intraclass correlation coefficients (ICCs) ranging from 0.01 to 0.08, though one was as high as 0.20; however, observations explained large percentages of between-school variation in climate (58%–91%). Findings suggest the potential utility of outside observations for explaining school-level variation in school climate to inform decision-making and future research.     

THE AMBIGUITY OF MORAL EXCELLENCE: A Response to Aaron Stalnaker's “Virtue as Mastery”

This response draws on Saba Mahmood's work on Muslim subjectivities in order to consider how Stalnaker's conceptualization of virtue might be applied to non‐Confucian sources. I argue that when applied cross‐culturally, Stalnaker's revised definition of “skillful virtue” raises normative and metaethical questions about what counts as a skill versus a mere bodily practice, the process by how skill is acquired, and how we can both allow for the ambiguity of skills and continue to make constructive arguments about them.     

Questionable research practices among Brazilian psychological researchers: Results from a replication study and an international comparison

Research on scientific integrity is growing in psychology, and questionable research practices (QRPs) have received more attention due to its harmful effect on science. By replicating the procedures of previous research, the present study aimed at describing the use of QRPs among Brazilian psychological researchers and to make an international comparison with previous studies in other countries—the US and Italy. Two hundred and thirty-two Brazilian researchers in the field of psychology answered questions related to 10 different QRPs. Brazilian researchers indicated a lower tendency to engage in two QRPs (failing to report all of a study's dependent measures; deciding whether to collect more data after looking to see whether the results were significant) when compared to their Italian and North American counterparts, but indicated a higher tendency to engage in two other QRPs (selectively reporting studies that “worked”; not reporting all of a study's conditions). Most of the sample did not admit integrity conflicts in their own research but indicated that others have integrity problems, as observed in previous studies. Those discrepancies could be attributed to contextual and systemic factors regarding different publication demands among the different nations. Further studies should focus on identifying the antecedents of QRPs.
