Active learning: A small group histology laboratory exercise in a whole class setting utilizing virtual slides and peer education

Histology laboratory instruction is moving away from the sole use of the traditional combination of light microscopes and glass slides in favor of virtual microscopy and virtual slides. At the same time, medical curricula are changing so as to reduce scheduled time for basic science instruction as well as focusing on student‐centered learning approaches such as small group active learning and peer‐instruction. It is important that medical schools resist the temptation to respond to this conjunction of events by turning histology into a self‐study activity. This article describes a lymphoid histology laboratory exercise, occurring in a specially equipped Learning Studio housing an entire medical class that utilizes virtual slides in the context of small group active learning and peer instruction.

晏阳初:我国电化教育早期的践行者

晏阳初是著名的平民教育家。在20世纪前半叶,为中国的平民教育做出了突出的贡献。晏阳初把幻灯、广播、电影等当时最先进的电化教育手段应用于平民教育运动,在华工识字教育、平民识字教育、军队识字教育,尤其是定县的乡村建设实验中,取得了巨大的成功,大大提高了社会教育的效果和效率。晏阳初对电化教育的践行和农村改革的经验,对当前社会主义新农村的建设仍然有一定的借鉴作用。     

HistoViewer: An interactive e‐learning platform facilitating group and peer group learning

Understanding tissue architecture and the morphological characteristics of cells is a central prerequisite to comprehending the basis of physiological tissue function in healthy individuals and relating this to disease states. Traditionally, medical curricula include courses where students examine glass slides of cytological or tissue samples under a light microscope. However, it is challenging to implement group and peer group learning in these courses and to give students sufficient time to study specimens. An increasing number of medical schools have thus started to implement digital slide viewers, so‐called virtual microscopes, in histology and histopathology. These websites are mostly based on standard commercial software and offer limited adaptation to the special needs of first‐year students. An e‐learning platform has therefore been developed for use in cytology and histology courses. This virtual microscopy tool is coupled to a central database in which students can label and store the positions of individual structures for later repetition. As learning in pairs and peer groups has been shown to provide a high learning outcome, identified structures can be shared and discussed with students' peers or faculty via a built‐in communication module. This website has the possibility of opening an arbitrary number of frames which all can actively be moved and changed in magnification to enable the comparison of specimens and thus encourage a more global understanding of related tissues. HistoViewer is thus suggested as an e‐learning tool combining several modern teaching concepts. © 2013 American Association of Anatomists.
