This paper seeks to interrupt the dominant discourse of action research that emphasises the celebration of achievements, paying less attention to the ‘unwelcome truths’ that can sometimes be revealed. Building on our work in supporting inservice teacher professional learning thorough practitioner research in contexts such as the Coalition of Knowledge Building Schools, we examine the capacity of practitioner inquiry and student voice to contribute to teachers’ broader professional knowledge base. Welcoming ‘unwelcome truths’ requires a robustness on the part of teachers, an openness to the professional learning and growth that can ensue from genuine critique and reflection. Among other things, asking questions of young people in schools can sometimes yield new and challenging insights into school and learning. We draw on examples from our work with schools and teachers to consider what might be done to make these ‘unwelcome truths’ the basis for the reconceptualisation of practice and catalysts for the ongoing formation of teacher professional identity.  相似文献

This study examined sexual content in American prime-time programs popular among the tween (9–14 years of age) audience on broadcast networks and programs aired on the most popular adolescent TV networks—an understudied area of media research. Consistent with past research, the majority of broadcast shows contained sexual talk and behaviors, as did adolescent shows. No significant difference was observed between the two types of shows regarding the frequency with which sexual behaviors were presented in a given hour of TV programming. The amount of scene focus paid to sexual themes varied, but studio audiences were almost always heard positively reinforcing these messages. The findings are discussed with respect to social cognitive and cultivation theories.  相似文献

ABSTRACT

Poor comprehenders (PCs) are characterized by poor reading comprehension despite intact decoding and general cognitive ability. Poor word meaning knowledge is one of the earliest deficits associated with a PC profile. We examined processes underpinning word learning in PCs using a category learning paradigm. Adolescent participants (20 typically developing [TD], 19 PC, ages 13–18 years) learned novel categories with two key manipulations: information type (verbal vs. nonverbal) and training type (directed vs. undirected). We found that PCs showed more benefit from directed training than TD individuals overall; however, both groups performed similarly when receiving directed blocks first. Moreover, when undirected training was received first, TD individuals showed better performance in directed as compared to undirected blocks, whereas PCs who receive undirected training first showed no significant difference between training types. Our investigation indicates that PCs may have different strategies for learning, especially when their attention is not externally directed toward relevant features.  相似文献

The original mission of the state and land-grant university was to engage with communities to solve problems and improve the quality of life for the citizenry. Today most state and land-grant universities have moved far away from their original mission and are struggling to become engaged with the communities they serve. In this case study, we highlight some of the steady progress toward engagement that has recently occurred at The Pennsylvania State University. We catalogue how strong vision and leadership; infrastructure reorganization; and the active involvement of faculty, students, and community partners have revitalized the land-grant mission at Penn State.

Dr. Aronson received his B.A. from Rutgers University, M.A. from Ball State University, and Ph.D. from The Pennsylvania State University. He is a clinical psychologist with a specialization in biobehavioral health and is interested in understanding how research conducted at universities and colleges can better impact communities.

Gender segregation in employment may be explained by women's reluctance to choose technical occupations. However, the foundations for career choices are laid much earlier. Educational experts claim that female students are doing better in math and science and are more likely to choose these subjects if they are in single-sex classes. One possible explanation is that coeducational settings reinforce gender stereotypes. In this paper, we identify the causal impact of the gender composition in coeducational classes on the choice of school type for female students. Using natural variation in the gender composition of adjacent cohorts within schools, we show that girls are less likely to choose a traditionally female dominated school type and more likely to choose a male dominated school type at the age of 14 if they were exposed to a higher share of girls in previous grades.  相似文献

Evidence suggests that oral narrative skills are a linguistic strength for African American children, yet few studies have examined how these skills are associated with reading for African American boys and girls. The current study uses longitudinal data of a sample of 72 African American 4‐year‐olds to examine how preschool oral narrative skills predict reading from first through sixth grades and explores differences by gender. Findings indicate that although girls demonstrated stronger narrative skills, their narrative skills did not moderate change in reading. For boys, narrative skills moderated change in reading over time such that as preschool narrative skills increased, their reading scores showed greater change over time. Educational implications and directions for future research are discussed.  相似文献

This study applied Messick's unified, multifaceted concept of construct validity to an electronic portfolio system used in a teacher education program. The subjects included 128 preservice teachers who recently completed their final portfolio reviews and student teaching experiences. Four of Messick's six facets of validity were investigated for the portfolio in this study, along with a discussion of the remaining facets examined in two previous studies. The evidence provided support for the substantive and generalizability aspects of validity, and limited support for the content, structural, external, and consequential aspects of validity. It was suggested that the electronic portfolio may be used as one requirement for certification purposes, but may not be valid for the purpose of assessing teacher competencies .  相似文献

The purpose of this review was to identify the different augmented reality (AR) modalities used to teach anatomy to students, health professional trainees, and surgeons, and to examine the assessment tools used to evaluate the performance of various AR modalities. A scoping review of four databases was performed using variations of: (1) AR, (2) medical or anatomical teaching/education/training, and (3) anatomy or radiology or cadaver. Scientific articles were identified and screened for the inclusion and exclusion criteria as per Preferred Reporting Items for Systematic Reviews and Meta-Analyses with extension for scoping reviews guidelines. Virtual reality was an exclusion criterion. From this scoping review, data were extracted from a total of 54 articles and the following four AR modalities were identified: head-mounted display, projection, instrument and screen, and mobile device. The usability, feasibility, and acceptability of these AR modalities were evaluated using a variety of quantitative and qualitative assessment tools. Within more recent years of AR integration into anatomy education, the assessment of visuospatial ability, cognitive load, time on task, and increasing academic achievement outcomes are variables of interest, which continue to warrant more exploration. Sufficiently powered studies using validated assessment tools must be conducted to better understand the role of AR in anatomical education.  相似文献
