A java applet for exploring the new higher level classification of eukaryotes with emphasis on the taxonomy of protists

ABSTRACT. We have converted the hierarchically organized new higher level classification of eukaryotes with emphasis on the taxonomy of protists proposed by Adl et al. into an interactive and dynamic Java applet. The current version of the applet can be accessed via http://phylogenetics.bioapps.biozentrum.uni-wuerzburg.de/etv . We use the layout from a Degree-of-Interest tree (DOITree) that effectively displays all the taxonomic information as well as the phylogenetic relationships described in the original article by Adl et al. The tree was made using the Prefuse Toolkit for interactive information visualization. All browsers capable of using Java applets will be able to view the tree. The applet is freely available for scientists, teachers, and students.     

Enhancing students’ experimental planning competences by introducing and evaluating the IS4O teaching approach

ABSTRACT

We herein report the introduction of the IS⁴O (Improving Students’ Scientific Skills by Using Scaffolding Outlines) teaching approach and its implementation to successfully empower students with initial minor planning competences in mastering complex scientific challenges in the course of Germany’s most-renowned scientific competitions. The IS⁴O teaching approach itself comprises the unique combination of the differentiating teaching methods Backward Planning and Project Mapping as core teaching elements. The beneficial effect of the IS⁴O teaching approach on the enhancement of the students planning competences is also discussed. Based on the given results, this teaching approach is mandatory to empower students with initial minor competences in completing a scientific competition successfully with very high assignment of tasks.     

An ecological energetics field course for sixth forms

the field course described has recently been piloted with a sixth-form group and is currently undergoing a more extensive evaluation. It consists of written materials for students and a teacher's booklet giving all the necessary techniques, lists of apparatus, and practical hints. The course aims to estimate the energy flows in a woodland ecosystem by means of a series of practical sessions involving field and laboratory investigations and calculation.

It is hoped the course will eventually be published and made generally available. designed with the non-ecologist teacher in mind. By using the supporting materials any teacher should be able to run the course.     

Development of an Undergraduate Bioinformatics Degree Program at a Liberal Arts College

The highly interdisciplinary field of bioinformatics has emerged as a powerful modern science. There has been a great demand for undergraduate- and graduate-level trained bioinformaticists in the industry as well in the academia. In order to address the needs for trained bioinformaticists, its curriculum must be offered at the undergraduate level, especially at four-year colleges, where a majority of the United States gets its education. There are many challenges in developing an undergraduate-level bioinformatics program that needs to be carefully designed as a well-integrated and cohesive interdisciplinary curriculum that prepares the students for a wide variety of career options. This article describes the challenges of establishing a highly interdisciplinary undergraduate major, the development of an undergraduate bioinformatics degree program at Ramapo College of New Jersey, and lessons learned in the last 10 years during its management.     

做好实验准备工作,提高微生物学实验教学质量

完善的微生物学实验准备工作是确保实验成功的开始,也是提高微生物学实验教学质量的重要环节。从加强实验室管理,制定详细的实验准备内容,严格进行实验预做等方面介绍做好微生物学实验准备工作的经验,为提高实验教学质量,培养具有创新能力的人才提供参考和借鉴。     

基因突变的教学设计

教学设计围绕基因突变这一核心概念,设计多样化的教学活动,让学生从实例分析入手,按照认知的规律从现象到概念,从宏观到微观来归纳总结出基因突变的概念;利用环环相扣的问题、科研资料引导学生在不断地探究、思考、分析和讨论,理解基因突变特征和基因突变的意义。     

基于网络环境下植物学实验课程的设计与构建

植物学实验网络课程是植物学实验教与学的网络平台。探讨网络环境下植物学实验课程体系的结构和网络教学系统组成,通过建立植物学实验网络辅助教学系统并予以应用,优化整合资源,探索提高植物学实验教学质量的途径。     

琥珀酸脱氢酶实验的优化设计

琥珀酸脱氢酶作用的实验是《生物化学》课程的重要实验之一。由于材料来源、成本、操作、结果等在实验教学中存在的问题,影响了该实验的效果和开出率。采用普通鸽子胸脯处肌肉作为实验材料,并对实验条件和程序进行优化,从而使教学取得了较好的效果,实验开出率也得以提高。     

PBL 结合案例教学法在病理生理学教学中的应用

以问题为基础(Problem-based learning,PBL)的教学法和案例教学法都是近年来我国医学教育改革中经常采用的两种新型教学方法。但二者从教学论方面来看,在教学材料的选择上、教学目的上都存在着差别。病理生理学是沟通基础和临床各学科间的桥梁学科,将"以问题为基础"的教学模式与案例教学法有机地结合引入病理生理学教学,符合病理生理学的学科特点,能够有效提高教学质量,在教育观念上更易于被医学生所接受,因而适应对高素质医学人才培养的需要。
