In this activity for the beginning of a high school Biology 1 evolution unit, students are challenged to reconstruct organisms found in an owl pellet as a model for fossil reconstruction. They work in groups to develop hypotheses about what animal they have found, what environment it inhabited, and what niche it filled. At the end of the activity,…

Large enrolment science courses play a significant role in educating undergraduate students. The discourse in these classes usually involves an instructor lecturing with little or no student participation, despite calls from current science education reform documents to elicit and utilize students' ideas in teaching. In this study, we used the 5E…

The web has created new possibilities for collaboration that fit under the terms crowdsourcing and human-based computation. Crowdsourcing applies when a task or problem is outsourced to an undefined public rather than a specific body. Human-based computation refers to ways that humans and computers can work together to solve problems. These two…

How do viruses self-assemble? Why do DNA bases pair the way they do? What factors determine whether strands of proteins fold into sheets or helices? Why does handedness matter? A deep understanding of core issues in biology requires students to understand both complex spatial structures of molecules and the interactions involved in dynamic…

This study investigated the consciousness of the pre service teachers of nesting animals in certain ecosystems. The study group included primary school and subject teacher students. The students were asked to name 10 different nesting animal species in each ecosystem drawing. Spruce dominated coniferous forest got the highest number of animals…

This paper proposes an indicator that integrates life expectancy with the demographic structure of the population for a given society. By doing this, we have a simple indicator of mortality and aging combined, which could be very useful for developed societies. As is widely known, life expectancy at birth is independent of the demographic…

The Interagency Autism Coordinating Committee (IACC) is a federal advisory committee that advises the Secretary of Health and Human Services (HHS) on issues related to autism spectrum disorder (ASD). It was established by the "Children's Health Act of 2000" (Public Law 106-310), reconstituted under the Combating Autism Act of 2006 (CAA;…

Background: Education Standards highlight the importance of conceptual knowledge. Instructional tasks play a key role in biology instruction and offer learning opportunities for students. Tasks contain of a content and a demands part. Therefore, complexity and cognitive level are adequate variables to describe tasks and are assumed effective for…

This paper reports on the contribution to biological knowledge of three different laboratory technologies and also endeavours to discover which technology students prefer the most. To examine differences in knowledge gained and learners' preferences for different technologies in biology laboratory work, we prepared three variants (triplets) of…

This article considers how professional writing courses can prepare students in various disciplines for the workforce. Specifically, I argue for Writing in the Disciplines (WID) internships where students learn to write documents relevant for their careers while participating in practical work experiences. In the WID internships I describe,…

The focus of this study was student teachers at a South African university enrolled in a Bachelor of Education (B.Ed.) programme and a Postgraduate Certificate in Education (PGCE), respectively. The purpose of this study was to explore students' understanding and acceptance of evolution and beliefs about the nature of science (NOS), and to…

This paper presents a profile on how teachers in senior secondary schools in Bauchi state Nigeria utilise animated instructional resource (AIR) in the teaching of biology. A structured questionnaire used to generate data on the availability, accessibility and application of the AIR for classroom instruction by teachers. The instrument for data…

Many students feel the curriculum is detached from their lives and interests. Indeed, about half the questions asked by high school biology students are not addressed by the curriculum. This study presents a strategy to incorporate students' curiosity questions into the curriculum as a way to reduce the disparity between students' interests and…

Learning is crucial for everyone. The association between biological (eg, sleep, nutrition) and psychological factors (eg, test anxiety, goal orientation) and learning performance has been well established for children, adolescents and college students in traditional education. Evidence for these associations for adult distance students is lacking…

This study demonstrates the use of wiki technology (an editable webpage environment) to provide a virtual, asynchronous collaborative-learning environment for students for the purpose of working on course-content-focused study-guide questions. To analyze the effectiveness of this course tool, students' responses to various qualitative and…
