传统《诗经》学的重大历史转折——朱熹“以《诗》言《诗》”说申论

朱熹首倡并躬行的“以《诗》言《诗》”说是对《诗序》”以史证《诗》”以及后儒“以《序》解《诗》”的否定与批判，同时又体现了对《诗经》文学本质与诗歌创作规律的深刻认识。贯彻“以《诗》言《诗》”的原则，实现传统《诗经》学的重大变革，是历史的发展与时代的需求赋予宋代学者的重大使命；而文学名家与经学大师的一身兼任，历代文学与历代经学的双轨集成，是朱熹实现《诗经》学变革的主体条件怀客观基础。     

新工科背景下音乐公选课实践教学方式初探——以《西方音乐史》实践教学为例

工科类高校音乐公选课实践教学设计与学生专业背景之间的契合度,是真正实现学校音乐教育目标的重要基础。尤其对于培养工科学生感性思维、跳跃性思维,以及对于新兴的交叉学科背景的学生专业审美等方面水平的提升都有着至关重要的作用。文章将在概述目前大多数工科类高校音乐公选课实践教学基本现状的基础上,以《西方音乐史》实践教学为例,从课程内容设置、知识点导入,从趣味实践教学案例设计等方面展开创新教学实践,并对实践教学的成果进行总结。     

A sociocultural perspective on mediated activity in third grade science

This ethnographic study of a third grade classroom examined elementary school science learning as a sociocultural accomplishment. The research focused on how a teacher helped his students acquire psychological tools for learning to think and engage in scientific practices as locally defined. Analyses of classroom discourse examined both how the teacher used mediational strategies to frame disciplinary knowledge in science as well as how students internalized and appropriated ways of knowing in science. The study documented and analyzed how students came to appropriate scientific knowledge as their own in an ongoing manner tied to their identities as student scientists. Implications for sociocultural theory in science education research are discussed. John Reveles is an assistant professor in the Elementary Education Department at California State University, Northridge. He received his Ph.D. from the University of California, Santa Barbara in 2005. Before pursuing his Ph.D., he worked as a bilingual elementary school teacher for 3 years. His research focuses on the development of scientific literacy in elementary school settings; sociocultural influences on students' academic identity; equity of access issues in science education; qualitative and quantitative research methods. Within the Michael D. Eisner College of Education, he teaches elementary science curriculum methods courses, graduate science education seminars, and graduate research courses. Gregory Kelly is a professor of science education at Penn State University. He is a former Peace Corps Volunteer and physics teacher. He received his Ph.D. from Cornell in 1994. His research focuses on classroom discourse, epistemology, and science learning. This work has been supported by grants from Spencer Foundation, National Science Foundation, and the National Academy of Education. He teaches courses concerning the uses of history, philosophy, sociology of science in science teaching and teaching and learning science in secondary schools. He is editor of the journal Science Education. Richard Durán is a Professor in the Gevirtz Graduate School of Education, University of California, Santa Barbara. His research and publications have been in the areas of literacy and assessment of English Language Learners and Latino students. He has also conducted research on after school computer clubs, technology and learning as part of the international UC Links Network. With support from the Kellogg Foundation, he is implementing and investigating community and family-centered intervention programs serving the educational progress of Latino students in the middle and high school grades.     

Impact of Anatomy Boot Camp on Students in a Medical Gross Anatomy Course

Lincoln Memorial University‐DeBusk College of Osteopathic Medicine (LMU‐DCOM) offers an optional three‐week summer Anatomy Boot Camp course (ABC) to facilitate students' transition into medical school and promote retention of anatomy subject matter. The pre‐matriculation program is a supplemental instruction course that utilizes a small group learning format. Boot camp instruction is led by teaching assistants and two anatomy professors. Enrollees gain early exposure to Medical Gross Anatomy (MGA) course subject matter, which is taught in the fall semester, and learn study skills necessary to excel in medical school. No grade is assigned for the course, therefore participants can study without the fear of potentially affecting grades. This study evaluates the effectiveness of the LMU‐DCOM ABC course using data from four consecutive summers. Independent two‐sample t‐tests were used to compare ABC to non‐ABC students for the following variables: incoming grade point average (GPA) and Medical College Admission Test® (MCAT®) scores, MGA written and laboratory practical examination grades, and final MGA course grade. Additionally, a 26‐question survey was administered to 2012–2014 boot camp participants. There were no significant differences in incoming GPA and MCAT scores. However, boot campers scored significantly higher on the first two lecture and laboratory examinations (P < 0.05) for each year of the study. Thereafter scores varied less, suggesting a faster head start for boot camp participants. Mean MGA final grade was on average 3% higher for the boot camp cohort. The survey feedback supports that the ABC course assists with the academic and social transition into medical school. Anat Sci Educ 10: 215–223. © 2016 American Association of Anatomists.

利用DOS中断实现显示器的定时关闭

当用户一段时间不使用计算机时,可以关闭显示器,这样既可以节约电能,也可以避免不必要的辐射,但一般情况下系统只提供固定的时间,不能任意设置.通过使用DOS中断,可随意设置时间,实现显示器的定时关闭。
