Integrating Concepts in Biology: A Model for More Effective Ways to Introduce Students to Biology

This is a review of Integrating Concepts in Biology, an innovative electronic textbook intended for either or both semesters of a typical introductory biology sequence. The e-book is an excellent example of effective pedagogy informed by recent educational scholarship.Integrating Concepts in Biology (ICB) is the apt title of this groundbreaking electronic textbook (see Supplemental Material). The target audience is students seeking an introduction to biology. It is structured to focus student attention on key concepts underlying biology at all levels of organization. In contrast to the current encyclopedic model of an introductory textbook, this e-book makes effective use of electronically linked text and online resources, selects examples to explore in depth, and offers students means to deepen their understanding. It explicitly uses current ideas about student learning, supported by evidence of best practices, to help students develop as biologically literate thinkers. The authors are colleagues at Davidson College: biologists A. Malcolm Campbell (cellular and molecular biology) and Christopher J. Paradise (ecology) and mathematician/computer scientist/bioinformaticist Laurie J. Heyer. They share a common passion for innovative pedagogy and multidisciplinarity, and ICB is their laudable effort to address many of the widely recognized problems evident in introductory biology texts and introductory courses and explored in recent reports such as BIO2010 (National Research Council [NRC], 2003 ) and Vision and Change in Undergraduate Biology Education (American Association for the Advancement of Science, 2011 ).

STEM the Boredom: Engage Students in the Australian Curriculum Using ICT with Problem-Based Learning and Assessment

The well-being of modern economies and societies is increasingly requiring citizens to possess capabilities in integrating knowledge and skills in science, technology, engineering and science to solve problems. However, by the end of schooling, the majority of Australian students show little interest in these discipline areas and have no plans to continue study or work in them; many refer to these disciplines as boring. Further, they typically have little experience in integrating knowledge and skills from these disciplines and/or in applying this to solve relevant problems. Therefore, there is a need to engage students with such learning experiences to develop their interest and capabilities, particularly during the early years of secondary schooling. This is not easy for teachers to respond to, but with the support of modern digital technologies and the new Australian curriculum, the potential is expanded and the challenge is more readily achievable. However, appropriate pedagogies need to be supported that include more authentic approaches to assessment. Learning activities need to support students to integrate knowledge and skills across discipline areas in tackling real problems, and this also needs to be reflected in how students are assessed. In this paper, I will draw on personal experience as a teacher, a review of recent literature, components of the Australian Curriculum, and findings from research projects associated with my University research centre, to argue for, and illustrate how, teachers can orchestrate powerful learning activities to promote an interdisciplinary approach to STEM.

乡土基,成本低:提高农村初中生物理实验操作技能的实践探索

物理实验是学生理解物理概念、探究物理规律的基础,是培养学生实践能力和创新能力的重要途径。然而,在一些穷困的农村地区,学校无法配备全初中物理实验所需要的器材,使得学生不能更具体地理解知识。对此,我们应根据乡土实际情况,探索低成本的物理实验教学,以提高学生的参与积极性、动手能力和学习兴趣。     

Using Metaphor Theory to Examine Conceptions of Energy in Biology,Chemistry, and Physics

Energy is one of the most important unifying themes in science. Yet the way energy is conceptualized varies depending on context. In this paper, the discourse used to explain the role of energy in systems from biology, chemistry, and physics is examined from the perspective of metaphor theory. Six substance metaphors for energy are identified in pedagogical discourse (i.e., textbooks and the science education literature): energy as a substance that can be accounted for, can flow, can be carried, can change forms, can be lost, and can be an ingredient, a product or stored in some way. Each of these conceptual metaphors highlight and obscure various characteristics of energy, and provide a set of frameworks that each afford a different understanding of the energy concept.

Just-in-Time Teaching Exercises to Engage Students in an Introductory-Level Dinosaur Course

The Just-in-Time Teaching (JiTT) technique allows students to be engaged in course material outside of the classroom by answering web-based questions. The responses are summarized and presented to students in class with a follow-up active learning exercise. College students enrolled in an introductory-level general education geoscience course were surveyed over a two-semester period on their engagement level during lecture and perceived learning of course content. Data show that students are able to reflect on their prior knowledge and construct new knowledge with weekly graded JiTT exercises. Despite increasing and competing pressures outside of the classroom, students reported increased learning and engagement in a course with required weekly assignments.     

初中生物实验教学中学生探究能力的培养

1生物实验中培养学生探究能力的必要性传统的生物实验多为演示型实验和验证型实验,实验课上教师向学生演示实验步骤,学生根据教师的指导,按照实验步骤操作,观察实验现象,最后得出实验结论.在整个实验课上,学生只是按照教师的流程在走,没有真正思考问题和解决问题,学生的探究能力也得不到提高.

What They Learned: Using Multimedia to Engage Undergraduates in Research

Today’s employers seek high levels of creativity, communication, and critical thinking, which are considered essential skills in the workplace. Engaging undergraduate students in critical thinking is especially challenging in introductory courses. The advent of YouTube, inexpensive video cameras, and easy-to-use video editors provides opportunities to increase students’ skill levels in these areas. In this article I explain the assignment of producing a public service announcement that integrates research, collaborative learning, and creativity into an introductory survey course; and I discuss the support necessary for students’ success. Their products demonstrate increased levels of media literacy, creativity, and critical thinking skills.
