Using data from the National Longitudinal Survey of Youth ( N  =   1,159), this study reexamines the link between maternal reports of television viewing at ages 1 and 3 and attention problems at age 7. This work represents a reanalysis and extension of recent research suggesting young children's television viewing causes subsequent attention problems. The nonlinear specification reveals the association between television watching and attention problems exists—if at all—only at very high levels of viewing. Adding 2 covariates to the regression model eliminated even this modest effect. The earlier findings are not robust. This study also considers whether its own findings are sensitive to unobserved confounding using fixed-effects estimation. In general, it finds no meaningful relation between television viewing and attention problems.  相似文献

Massive oil revenues are currently fueling a surge in the number of educational institutions in the Gulf Cooperation Council (GCC) countries, presenting leadership at all levels with many unprecedented questions. In particular, the growth and reform of higher education challenges the delicate balance between academic freedom and Arab cultural values. This paper describes faculty perceptions of academic freedom at a major GCC national university. Faculty members’ views and perceptions regarding academic freedom are presented based on interviews, questionnaire responses, and the authors’ own thoughts. Findings indicate that faculty members have complex and often contradictory understandings of academic freedom and related responsibilities and often engage in self-censorship. The authors discuss these findings by engaging in self-reflection regarding their own perspectives and personal experiences.  相似文献

Given the serious decline in the number of undergraduates majoring in the humanities in general, and literature in particular, teachers of Children’s Literature have a unique opportunity to serve their discipline by tapping the power of classroom dialogue to introduce students to the practical reasoning central to humanistic study. This essay takes Long John Silver, from Robert Louis Stevenson’s Treasure Island (1883), as a model for generating lively discussion that begins with literary matters but leads, with help from the teacher, to fundamental questions about the role of the humanities in students’ education and in their lives. In the process, the essay traces a pedagogical strategy that moves from matters of plot and character, to issues of ethics and judgment, to larger questions regarding approximate knowledge and sound reasoning about the complexities of the human condition. This inquiry focuses specifically on the charming but villainous Silver and the possible explanations for his escape at the end of the novel. But the ambiguity and fascination of his character are also catalysts for wide-ranging classroom discussion of a kind that Children’s Literature routinely promotes and sustains. Such discussion can provide broad, balanced insight into the nature and variety of critical understanding. As such, Children’s Literature and the pedagogy it supports serves to identify and enliven the benefits of humanistic study at a crucial moment of academic history.  相似文献

Privacy has been defined as “the protective buffer within which people can avoid another party’s taking something from them, keeping watch over them, or entering into their lives in a way that is both unwelcome and undesirable”. It is a premise of this paper that such a position needs to be taken very seriously in contemporary society, and particularly in the case of schools, as school personnel have the capacity to engage in practices which show great disregard for individual and family privacy. This is illustrated in the case of primary school education in the Republic of Ireland. Particular attention is paid to assessment, pedagogical and curricular practices that derive from patterns of systematic and mandatory disclosure that are confessional, performative and public.  相似文献

This article argues for increased theoretical specificity in the active learning process. Whereas constructivist learning emphasizes construction of meaning, the process articulated here complements meaning construction with disciplinary critique. This process is an implication of how disciplinary communities generate new knowledge claims, which is comprised by an interaction of roles – authors construct claims and peers critique them. Because disciplinary critique drives and shapes generation of knowledge claims, specialized features of these claims both justify and define their meaning. Here science is offered as an example, in which critique drives measurement of key concepts, thereby anchoring their meaning in operational definitions. The account of active learning proposed sheds new light on both historical and contemporary characterizations of active learning in terms of taking a critical stance toward content, in which the learner questions and challenges content. Thus students, rather than teachers, should actively challenge their emerging understanding of content.  相似文献

This study examined the influence of differing volume load and intensity (%1 repetition maximum[%1RM]) resistance exercise workouts on session rating of perceived exertion (sRPE) countermovement jump (CMJ) performance and endocrine responses. Twelve participants performed a workout comprising four exercises (bench press, back squat, deadlift and prone bench pull) in randomised order as either power (POW); 3 sets × 6 repetitions at 45%1RM × 3 min inter-set rest, strength (ST); 3 sets × 3 repetitions at 90%1RM × 3 min inter-set rest, or hypertrophy (HYP); 3 sets × 10 repetitions at 70%1RM × 1 min inter-set rest in a randomised-crossover design. CMJ performance and endocrine responses were measured immediately pre-, post-, 12, 24, 48 and 72 h post-exercise. POW sRPE (3.0 ± 1.0) was lower than ST (4.5 ± 1.0) (P = 0.01), and both were lower than HYP (8.5 ± 1.0) (P = 0.01). Duration of CMJ decrement was longer (P ≤ 0.05) for HYP (72 h) compared to POW (12 h) and ST (24 h). Testosterone concentration was greater (P ≤ 0.05) immediately post-exercise in HYP compared to POW and ST. In conclusion, less inter-set rest, greater volume load and intensity (%1RM) may increase sRPE, duration of CMJ performance decrement and testosterone responses in resistance exercise.  相似文献
