Evaluating the veracity and reliability of online media in science is an integral part of developing critical skills in science. Moreover, the 1st year biology courses should provide an avenue for students to acquire these skills for academic success. This study evaluated whether students (n = 90) exposed to an apparently credible website were…

In 1858, Darwin published "On the Origin of Species by Means of Natural Selection." His explanation of evolution by natural selection has become the unifying theme of biology. We have found that many students do not fully comprehend the process of evolution by natural selection. We discuss a few simple games that incorporate hands-on…

Analyzing evolutionary relationships requires that students have a thorough understanding of evidence and of how scientists use evidence to develop these relationships. In this lesson sequence, students work in groups to process many different lines of evidence of evolutionary relationships between ungulates, then construct a scientific argument…

Students in introductory biology courses frequently have misconceptions regarding natural selection. In this paper, we describe six activities that biology instructors can use to teach undergraduate students in introductory biology courses how natural selection causes evolution. These activities begin with a lesson introducing students to natural…

The purpose of the study was to determine whether undergraduate students receiving web-based instruction based on traditional, key character, or classification instruction differed in their performance of insect identification tasks. All groups showed a significant improvement in insect identifications on pre- and post-two-dimensional picture…

Documents a case of model-building in biology through microanalysis of one student's interaction with "Science for Living: The Circulatory System (SFL)", an interactive multimedia resource prototype for research. Describes the student's learning goals, gains, and activities with particular attention to interactions with representations,…

Describes an award-winning bulletin board for introducing a unit on reptiles. This interactive bulletin board contains fun facts and counters common misconceptions about reptiles. Twelve true-false statements are hidden behind pull-up flaps. Four pictures ask students to identify the difference between often-confused animals. (PR)

Describes teaching strategies, including science activities, for challenging students' misconceptions about turtles and helping limited-English-proficiency students enhance their language proficiency. (PR)

Discusses traditional school demonstrations and experiments in hydrotropism. Explains that these experiments seem to "prove" hydrotropism, but yet most botanists reject hydrotropism. Teachers continue to teach the concept because it is logical and the experiments are simple. (PR)

Research shows that misconceptions about human blood circulation and gas exchange persist across grade levels. The purpose of this study was twofold: (1) to investigate the prevalence and persistence of blood circulation misconceptions among prospective elementary teachers; and (2) to evaluate the effectiveness of learning activities for…

The Department for Children, Schools and Families (DCSF) has contracted with the Learning and Skills Network to support awareness and take-up of Triple Science GCSEs through the Triple Science Support Programme. This publication provides an introduction to teaching and learning approaches for the extension topics within GCSE Biology. It highlights…
