浅析川北皮影的源流、特色及现状

皮影在起源和发展过程中,受到方士幻术和宗教文化的影响,其造型具有浓厚的民俗特征。川北皮影是四川皮影戏两大流派之一,造型生动、雕工精巧、表演细腻、唱腔优美、剧情风趣,曾走出国门。现状令人堪忧的川北皮影,在全世界对非物质文化遗产十分重视的情况下,我们应寻找皮影衰败的原因,起来保护、挽救这门民间艺术。     

‘Playing with or like the girls’: advancing the performance of ‘multiple masculinities in Black boys’ childhood play’ in U.S. early childhood classrooms

Play is a gendered activity among young children, especially boys. Boys often tend to be more actively engaged in the (re)production of gendered play. However, most research studies and conceptual papers have misread, ignored, devalued, or scrutinized the gendered ways Black boys engage in play. This idea is particularly true for Black boys who may not play within the monolithic gendered expectations of childhood play. Drawing from [Connell, R. W. (1995). Masculinities. Berkeley: University of California Press] notion of multiple masculinities, I propose what I call the performance of ‘multiple masculinities of Black boys’ childhood play’ to embrace the ways some Black boys engage in play activities, which may not fit within the performance of hegemonic and Black masculine norms and expectations. In so doing, I call for educators to broaden how we view Black boys, and our definition of Black masculinity so that embracing what might be traditionally called ‘less masculine’ and/or stereotypically feminine could be valued male traits. Recommendations are provided for early childhood educators to support the confluence of ways Black boys engage in play experiences.

Children's concepts of gears and their promotion through play

The mechanical transmission of motion, which is observable in gears’ turning direction (TD) and turning speed (TS) can be understood as part of the core concept “force and motion”. Previous studies have suggested that most children before the age of nine have naïve concepts of gears’ TD and TS. However, these studies relied on children's explanation data and might have therefore underestimated young children's potential. Moreover, these studies did not examine whether preschoolers can overcome their naïve concepts through teaching. Recently, educators have proposed guided play as an educational approach that combines children's play with teacher guidance in a purposefully designed environment. We conducted two subsequent studies. In Study 1, we investigated the children's (naïve) concepts of gears’ TD and TS with a cross‐sectional approach using a nonverbal test procedure. This study comprised 248 children aged 5–10 years and 73 adults. The results showed that the proportion of children with adequate concepts increased with age. More specifically, 7‐ to 8‐year‐olds differed significantly from 5‐ to 6‐year‐olds, indicating a developmental shift around this age. However, naïve concepts of TS were more persistent with age than naïve concepts of TD. Altogether, the results indicated the potential to foster 5‐ to 6‐year‐olds’ concepts of both TD and TS in an intervention. Thus, in Study 2, we developed and tested a guided play intervention to foster 5‐ to 6‐year‐old children's concepts of TD and TS. We conducted a prepost‐intervention design with a guided play group (n = 19) and a free play group (n = 21). The results suggested stronger learning gains in the guided play group (d_TD = 0.337, d_TS = 0.758) than in the free play group (d_TD = 0.224, d_TS = 0.158).     

Introducing and Developing Professional Standards in the Information Systems Curriculum

In light of growing concerns in the public and recent mandates from business program accrediting bodies and curricular task forces, the importance of teaching ethical topics in information systems programs is discussed. Innovative strategies used for teaching the application of ethical criteria to common situations are reviewed. Results of a survey of information systems faculty members in the US are presented and are compared to previous studies that related primarily to computer science and software engineering programs. Insight is provided into the topics, techniques, degree of coverage, and assessment techniques currently used when teaching ethics in computing-related programs. Key concerns and future work is also outlined.
