Many introductory biology courses amount to superficial surveys of disconnected topics. Often, foundational observations and the concepts derived from them and students' ability to use these ideas appropriately are overlooked, leading to unrealistic expectations and unrecognized learning obstacles. The result can be a focus on memorization at the expense of the development of a meaningful framework within which to consider biological phenomena. About a decade ago, we began a reconsideration of what an introductory course should present to students and the skills they need to master. The original Web-based course's design presaged many of the recommendations of the Vision and Change report; in particular, a focus on social evolutionary mechanisms, stochastic (evolutionary and molecular) processes, and core ideas (cellular continuity, evolutionary homology, molecular interactions, coupled chemical reactions, and molecular machines). Inspired by insights from the Chemistry, Life, the Universe & Everything general chemistry project, we transformed the original Web version into a (freely available) book with a more unified narrative flow and a set of formative assessments delivered through the beSocratic system. We outline how student responses to course materials are guiding future course modifications, in particular a more concerted effort at helping students to construct logical, empirically based arguments, explanations, and models.
许多基础生物学课程只是对互不相关的主题进行肤浅的调查。通常,基础观察以及从中得出的概念和学生恰当地运用这些观点的能力被忽视了,导致不切实际的期望和未被认识到的学习障碍。其结果可能是专注于记忆,而不是在其中考虑生物现象的有意义的框架内发展。大约十年前,我们开始重新考虑介绍性课程应该向学生呈现什么以及他们需要掌握的技能。最初的基于网络的课程设计预示了《愿景与变革》报告的许多建议;特别是,关注社会进化机制、随机(进化和分子)过程以及核心思想(细胞连续性、进化同源性、分子相互作用、偶联化学反应和分子机器)。受化学、生命、宇宙和万物综合化学项目的启发,我们将原始的网络版本转化为(免费提供)的书籍,具有更统一的叙述流程和通过 beSocratic 系统提供的一组形成性评估。我们概述了学生对课程材料的反应如何指导未来的课程修改,特别是更协调地帮助学生构建逻辑的、基于经验的论点、解释和模型。
