Lessons from animal teaching

Many species are known to acquire valuable life skills and information from others, but until recently it was widely believed that animals did not actively facilitate learning in others. Teaching was regarded as a uniquely human faculty. However, recent studies suggest that teaching might be more common in animals than previously thought. Teaching is present in bees, ants, babblers, meerkats and other carnivores but is absent in chimpanzees, a bizarre taxonomic distribution that makes sense if teaching is treated as a form of altruism. Drawing on both mechanistic and functional arguments, we integrate teaching with the broader field of animal social learning, and show how this aids understanding of how and why teaching evolved, and the diversity of teaching mechanisms.     

“新工科”背景下“生物分离工程”课程创新改革

“生物分离工程”是生物工程专业本科生的一门重要的专业必修课,是生物工程专业建立“新工科”课程体系的重要组成部分。本教学团队坚持“以学生发展为中心,以创新思维为核心”的教育理念,以“学习成果”为导向的创新理念,针对课程长期存在的“理论教学与实验课脱节,学生不能及时地将理论知识内化为实践能力”、“课程内容陈旧,与行业需求脱节”、“授课和考核方式相对单一,学生的专业能力和素质未能有效培养”等痛点问题开展教学改革,重构课程内容。打通理论课和实验课的界限,开展“线上+线下”混合教学,通过科研反哺教学,使课程内容紧跟行业发展前沿,充分利用现代信息技术手段开展更丰富的课堂教学活动,并对学生进行全程化、动态化和多样化的考核,全面提升学生的能力。     

慕课在生物化学课程教学中的作用——华南农业大学《生物化学》“MOOC+线上见面课”课程教学实践

生物化学不仅是生物类专业的基础课,也是发展最快的前沿课程之一。传统的线下教学模式面对生物化学的繁杂体系暴露出许多问题,通常教学效果不佳。随着互联网技术的发展,“互联网+”教育得到快速发展。慕课与微课等线上课程为许多高校提供了丰富的学习资源,钉钉课堂、腾迅课堂、雨课堂、微信交流平台等线上课程直播,也让学生足不出户就能实现同步学习。线上教学在新冠疫情期间成为全国大中小学院校的主要教学模式,但经过几年的推广,单纯的线上教学在教学效果方面也暴露出诸多问题。为充分发挥线上、线下教学的各自优势,混合式教学成为发展方向。华南农业大学在2019年初开始与智慧树平台合作,建立生物化学的教学慕课,在2020年新冠疫情期间,我校生物化学课程教学采用了“MOOC+线上见面课”的线上混合教学模式。教学反馈结果显示,学生单纯依靠MOOC并不能很好地完成生物化学的学习,但“MOOC+线上见面课”则获得了学生的普遍认可。该教学模式不仅能提高学生的学习兴趣和学习主动性,在一定程度上也能提升教学质量和学习效果,为今后“MOOC+线下课”的应用提供了参考。

Investigating Human Impact in the Environment with Faded Scaffolded Inquiry Supported by Technologies

Teaching science as inquiry is advocated in all national science education documents and by leading science and science teaching organizations. In addition to teaching science as inquiry, we recognize that learning experiences need to connect to students’ lives. This article details how we use a sequence of faded scaffolded inquiry supported by technologies to engage students meaningfully in science connected to their lives and schoolyards. In this approach, more teacher guidance is provided earlier in the inquiry experiences before this is faded later in the sequence, as students are better prepared to complete successful inquiries. The sequence of inquiry experiences shared in this article offers one possible mechanism for science teaching supported by technologies as an exemplar for translating teaching “science as inquiry” into practice.     

利用文献精读教学新模式优化遗传学教学

《遗传学》是生命科学相关专业本科阶段最重要的课程之一。近年来,随着生命科学领域研究的不断深入,新知识与新技术也在不断更新。但遗传学的教学模式目前仍以理论讲授为主,这使得抽象的原理难以被学生理解接受,直接影响了教学效果。因此探索新的教学模式尤为必要。2010年以来我校在生物技术专业《微生物遗传学》教学中开展了新教学模式——文献精读,文章从文献精读的前期课程基础,如何选择专业文献,怎样组织教学过程,开展文献精读对学生和教师的意义等方面全面分析了实施情况和应用价值,指出该教学模式体现了“前沿”和“经典”的结合,使书本的知识在实践中具体化,既提高学生的学习效果,激发学习兴趣,又开拓了学生的思路,锻炼其能力。这种教学模式为《遗传学》教学授课不断探索新的模式、在“精准医疗”时代下如何培养兼具临床与科研能力的医疗人才提供新思路。

Autonomy,Equality, and Teaching among Aka Foragers and Ngandu Farmers of the Congo Basin

The significance of teaching to the evolution of human culture is under debate. We contribute to the discussion by using a quantitative, cross-cultural comparative approach to investigate the role of teaching in the lives of children in two small-scale societies: Aka foragers and Ngandu farmers of the Central African Republic. Focal follows with behavior coding were used to record social learning experiences of children aged 4 to 16 during daily life. “Teaching” was coded based on a functional definition from evolutionary biology. Frequencies, contexts, and subtypes of teaching as well as the identity of teachers were analyzed. Teaching was rare compared to observational learning, although both forms of social learning were negatively correlated with age. Children received teaching from a variety of individuals, and they also engaged in teaching. Several teaching types were observed, including instruction, negative feedback, and commands. Statistical differences in the distribution of teaching types and the identity of teachers corresponded with contrasting forager vs. farmer foundational cultural schema. For example, Aka children received less instruction, which empirically limits autonomous learning, and were as likely to receive instruction and negative feedback from other children as they were from adults. Commands, however, exhibited a different pattern suggesting a more complex role for this teaching type. Although consistent with claims that teaching is relatively rare in small-scale societies, this evidence supports the conclusion that teaching is a universal, early emerging cognitive ability in humans. However, culture (e.g., values for autonomy and egalitarianism) structures the nature of teaching.     

独立学院分子生物学引导式教学改革实践

分子生物学是生命科学专业的基础课程,但由于信息量大、知识更新快、生物大分子之间的作用关系错综复杂,使得该课程内容庞杂抽象、较难理解。学生在学习过程中往往感到十分枯燥,从而失去了学习兴趣,学习效率不高。生物科学教研室通过学业自我效能感评价,科学地分析出独立学院学生的学习特点,并使用信息化引导、双语引导、模块引导及互动引导等方式对分子生物学教学进行了改革。教学改革评价显示,此次教学改革提高了分子生物学的教学效果,增强了学生学习的主动性,激发了学生的科研兴趣,为分子生物学教学改革提供了理论依据。

Interactive instruction of cellular physiology for remote learning.

The biomedical sciences are a rapidly changing discipline that have adapted to innovative technological advances. Despite these many advances, we face two major challenges: a) the number of experts in the field is vastly outnumbered by the number of students, many of whom are separated geographically or temporally and b) the teaching methods used to instruct students and learners have not changed. Today's students have adapted to technology--they use the web as a source of information and communicate via email and chat rooms. Teaching in the biomedical sciences should adopt these new information technologies (IT), but has thus far failed to capitalize on technological opportunity. Creating a "digital textbook" of the traditional learning material is not sufficient for dynamic processes such as cellular physiology. This paper describes innovative teaching techniques that incorporate familiar IT and high-quality interactive learning content with user-centric instruction design models. The Virtual Labs Project from Stanford University has created effective interactive online teaching modules in physiology (simPHYSIO) and delivered them over broadband networks to their undergraduate and medical students. Evaluation results of the modules are given as a measure of success of such innovative teaching method. This learning media strategically merges IT innovations with pedagogy to produce user-driven animations of processes and engaging interactive simulations.     

生物化学课程“四化”形成性考核体系的构建与实践

课程考核是评价课程教与学效果的重要方式,在人才培养过程中发挥了指挥棒的作用。本文针对目前我国高等院校课程考核普遍存在的主要问题,以生物类专业基础课程“生物化学”为载体,通过文献研究、调查反馈和实践检验等方法,探索构建并实践“四化”形成性考核体系。其中考核主体的扩大化在主体范畴和考核载体两层面进行构建,考核过程的动态化在过程节点和反馈时效两个层面进行构建,考核内容的生态化在面向个体和群体两个维度进行构建,考核方式的多元化在考核形式、考核方法和计分方式三个层面进行构建。经过我校6个专业的6轮优化实践,对学生的学习和教师的教学均产生显著促进作用。     

Teaching plastic surgery from different perspectives

Just as everyone has a different learning style, teachers too approach the task from different perspectives. There are five basic teaching perspectives or styles: transmission, apprenticeship, developmental, nurturing, and social justice. The acronym BIAS is useful to describe the beliefs, intentions, assessments, and strategies associated with each perspective. The authors present a hypothetical 1-week rotation in plastic and reconstructive surgery in which a student encounters instructors who embody the five basic teaching perspectives. By presenting these perspectives, the authors introduce valuable teaching techniques that can benefit all those charged with the education of learners along the spectrum from premedical to continuing education venues. Educational objectives include the following: (1) explain and illustrate different approaches to effective teaching in plastic surgery; (2) introduce readers to the Teaching Perspectives Inventory as a means of determining their primary teaching style; and (3) argue for a "plurality of the good" in teaching.
