先秦惜时主题与中国文学中的个体价值追求——主题学与先秦文学关系研究的一个回顾

《诗经》忧生惜时,愿安稳度过有限人生时日,侧重在个体价值体现的物质生活与社会生活系统;《楚辞》侧重在及时建功立业,个体价值政治生活和精神生活系统;孔子的科学安排人时间,孟子的不违农时,庄子的将时间观念淡化等,都体现了对个体自我价值的重视。对个体价值的关注,还导致先秦文学中对于个体梦中世界体系建构。围绕着原始心态、巫术思维来象征性地实现血族复仇义务和个体使命,提倡不失时机地成功复仇。由此还派生出梦中雪恨、变形复仇等多重想像。从而先秦文学主题,成为中国众多抒情文学和叙事文学的百川之始。学术史总结也要客观定位。

Class-time utilization in business schools in Tunisia

Tunisian Universities, like many other universities in the developing countries, do not adopt any textbooks and rather rely on classrooms as the main learning resource for the students. This study is concerned with observing what is going on inside the classrooms of five business schools. The collected data, relating to 75 randomly selected classes, show that the instructors are utilizing on average less than 55% of the time of the lecture for teaching purposes. From their side, the students recorded an attendance rate lower than 34%. The rate drops to 20% when excluding the students engaged in extraneous activities. These incredible figures raise serious questions about the academic learning of the students.     

Off-task behavior in elementary school children

This paper reports results from a large-scale observational study investigating attention allocation during instructional activities in elementary school students (kindergarten through fourth-grade). In Study 1, 22 classrooms participated while a more diverse sample of 30 classrooms participated in Study 2. This work investigated temporal patterns in children's attention allocation by collecting observational data on children's on- and off-task behaviors at three different time points (i.e., beginning, middle, and end of the school year) [Study 1]. We also investigated whether patterns of attention allocation changed as a function of student characteristics (gender, grade-level, SES), teachers' instructional design choices (instructional format and duration of an instructional activity), and school type (private, parochial, public charter schools) [Studies 1 & 2]. Children's patterns of attention allocation fluctuated over the course of the school year. Female students were found to be more on-task compared to male students. On-task behavior tended to decline as the instructional duration increased. The lowest rates of on-task behavior were observed while children were engaged in whole-group instructional formats. An effect of school type was found with higher proportions of on-task behavior observed in parochial schools. However, the effect of grade-level was equivocal across studies. These findings can begin to form a foundation for the development of research-based guidelines for instructional design aimed to support engagement among students in elementary classrooms.
