IE时代下的教务管理体系研究

随着我国经济的飞速发展,大众化教育阶段已经开始实施,无论是小学、初中、还是高校,招生规模每年都在扩大,在学生数量呈直线增长的同时,保证教学质量的稳定及其提高,确保达到育人的目标,是实现科教兴国路线的重要基础,也是每一位教育工作者需要思考的大事。加强教务管理是实现教学质量稳定及其提高的必要途径。教务管理工作是学校教学管理工作的核心驱动,只有做好教务管理,才能保证教学的正常秩序,有规律的实施教学计划,才能使教学质量得到稳定的发展。所以,为了跟上大众化教育的脚步,必须创建一套科学的、具有操作性的教务管理体系。     

Computer-assisted remedial reading intervention for school beginners at risk for reading disability

The aim of the longitudinal study was to investigate whether a computer application designed for remedial reading training can enhance letter knowledge, reading accuracy, fluency, and spelling of at-risk children. The participants, 7-year-old Finnish school beginners (N=166), were assigned to 1 of 3 groups: (a) regular remedial reading intervention (n=25), (b) computer-assessed reading intervention (n=25), and (c) mainstream reading instruction (n=116). Based on the results, computer-assisted remedial reading intervention was highly beneficial, whereas regular type of intervention was less successful. The results indicated that at-risk children require computer-based letter-name and letter-sound training to acquire adequate decoding and spelling skills, and to reach the level of their non-at-risk peers.     

Engaging Undergraduates in Science Research: Not Just About Faculty Willingness

Despite the many benefits of involving undergraduates in research and the growing number of undergraduate research programs, few scholars have investigated the factors that affect faculty members’ decisions to involve undergraduates in their research projects. We investigated the individual factors and institutional contexts that predict faculty members’ likelihood of engaging undergraduates in their research project(s). Using data from the Higher Education Research Institute’s 2007–2008 Faculty Survey, we employ hierarchical generalized linear modeling to analyze data from 4,832 science, technology, engineering, and mathematics (STEM) faculty across 194 institutions to examine how organizational citizenship behavior theory and social exchange theory relate to mentoring students in research. Key findings show that faculty who work in the life sciences and those who receive government funding for their research are more likely to involve undergraduates in their research project(s). In addition, faculty at liberal arts or historically Black colleges are significantly more likely to involve undergraduate students in research. Implications for advancing undergraduate research opportunities are discussed.

Microfluidic droplet encapsulation of highly motile single zoospores for phenotypic screening of an antioomycete chemical

Highly motile Phytophthora sojae (P. sojae) zoospores of an oomycete plant pathogen and antioomycete candidate chemicals were encapsulated into microdroplets. Random fast self-motion of P. sojae zoospores was overcome by choosing an appropriate flow rate for a zoospore suspension. To influence stochastic loading of zoospores into a microfluidic channel, a zoospore suspension was directly preloaded into a microtubing with a largely reduced inner diameter. A relatively high single zoospore encapsulation rate of 60.5% was achieved on a most trivial T-junction droplet generator platform, without involving any specially designed channel geometry. We speculated that spatial reduction in the diameter direction of microtubing added a degree of zoospore ordering in the longitudinal direction of microtubing and thus influenced positively to change the inherent limitation of stochastic encapsulation of zoospores. Comparative phenotypic study of a plant oomycete pathogen at a single zoospore level had not been achieved earlier. Phenotypic changes of zoospores responding to various chemical concentration conditions were measured in multiple droplets in parallel, providing a reliable data set and thus an improved statistic at a low chemical consumption. Since each droplet compartment contained a single zoospore, we were able to track the germinating history of individual zoospores without being interfered by other germinating zoospores, achieving a high spatial resolution. By adapting some existing droplet immobilization and concentration gradient generation techniques, the droplet approach could potentially lead to a medium-to-high throughput, reliable screening assay for chemicals against many other highly motile zoospores of pathogens.

运动生理学研究中的实际问题

从本世纪初运动员就作为体格健壮的理想对象被广泛地进行科学研究和探讨。然而至今仍仅有少量的从运动员身上测得的实验数据被用于提高他们的运动成绩,一些研究发现仅仅被用于解释运动后即刻或者长时间的生理反应。很少被反馈给教练员和运动员进行实际应用,因而运动中所产生的一些实
