Independent learning modules enhance student performance and understanding of anatomy

Didactic lessons are only one part of the multimodal teaching strategies used in gross anatomy courses today. Increased emphasis is placed on providing more opportunities for students to develop lifelong learning and critical thinking skills during medical training. In a pilot program designed to promote more engaged and independent learning in anatomy, self‐study modules were introduced to supplement human gross anatomy instruction at Joan C. Edwards School of Medicine at Marshall University. Modules use three‐dimensional constructs to help students understand complex anatomical regions. Resources are self‐contained in portable bins and are accessible at any time. Students use modules individually or in groups in a structured self‐study format that augments material presented in lecture and laboratory. Pilot outcome data, measured by feedback surveys and examination performance statistics, suggest that the activity may be improving learning in gross anatomy. Positive feedback on both pre‐ and post‐examination surveys showed that students felt the activity helped to increase their understanding of the topic. In concordance with student perception, average examination scores on module‐related laboratory and lecture questions were higher in the two years of the pilot program compared with the year before its initiation. Modules can be fabricated on a modest budget using minimal resources, making implementation practical for smaller institutions. Upper level medical students assist in module design and upkeep, enabling continuous opportunities for vertical integration across the curriculum. This resource offers a feasible mechanism for enhancing independent and lifelong learning competencies, which could be a valuable complement to any gross anatomy curriculum.

Distance Education in Bahrain: Situation and needs

In Bahrain, 36 international universities from 10 different countries provide distance education services through 21 local agencies to more than 800 students. Results from a survey suggest that the majority of the distance education students are working, married, of middle income class, and studying for a Bachelor's degree. The students find the distance education option attractive because: (1) there are a limited number of places in the conventional Bahrainian universities and on particular courses, and limited scholarships and financial support available for conventional students; (2) the distance system is more open and flexible in respect of their regulatory requirements; and (3) the students find it caters better for those with poor secondary school scores, low income, family and job responsibilities.     

多媒体CAI课件如何更好辅助教学

利用多媒体CAI课件辅助教学在高校老师的课堂中普遍都有应用,但大多是零碎自发的,没有统一的规划、标准和要求,如何规范课件基本要求,引导教师合理运用多媒体课件辅助教学,使之与传统教学更好地融合起来,需要教师依据教学目的、教学内容及硬件设施和学生的实际情况出发,进行优化选择。

Growth dynamics of citations of cumulative papers of individual authors according to progressive nucleation mechanism: Concept of citation acceleration

Using data generated by progressive nucleation mechanism on the cumulative fraction of citations of individual papers published successively by a hypothetical author, an expression for the time dependence of the cumulative number L_sum(t) of citations of progressively published papers is proposed. It was found that, for all nonzero values of constant publication rate ΔN, the cumulative citations L_sum(t) of the cumulative N papers published by an author in his/her entire publication career spanning over T years may be represented in distinct regions: (1) in the region 0 < t < Θ₀ (where Θ₀ ≈ T/3), L_sum(t) slowly increases proportionally to the square of the citation time t, and (2) in the region t > Θ₀, L_sum(t) approaches a constant L_sum(max) at T. In the former region, the time dependence of L_sum(t) of an author is associated with three parameters, viz. the citability parameter λ₀, the publication rate ΔN and his/her publication career t. Based on the predicted dependence of L_sum(t) on t, a useful scientometric age-independent measure, defined as citation acceleration a = L_sum(t)/t², is suggested to analyze and compare the scientific activities of different authors. Confrontation of the time dependence of cumulative number L_sum(t) of citations of papers with the theoretical equation reveals one or more citation periods during the publication careers of different authors.     

基于三垂面上形核的润湿角

对三垂面基体上非自发形核进行了研究. 根据非自发形核的条件,对临界形核半径和临界形核功进行了推导,得到了临界形核功与润湿角的数学表达式.结果表明,临界形核功仅与润湿角有关,说明润湿角在非自发形核中起非常重要的作用.对形核润湿角进行的讨论表明了,与自发形核相比,非自发形核具有更小的临界形核功.
