Describes a procedure for the datalogging of microbial population densities. (WRM)

Describes a partnership between Meadowgate School for students with special needs and Isle College in Wisbech, UK. Meadowgate School provides work experience placements for Isle College students, and the College provides classes for the school's special needs students. Outlines an initiative to provide science classes. (WRM)

Summarizes several articles on safety in the science laboratory, an article on the science and history of chocolate, and an article on teaching nuclear physics from an historical perspective. (WRM)

In this article, the author discusses "The Biology of Food" course. This course--a large lecture course with no laboratory section--is a mixture of kitchen chemistry, post-eating food metabolism, origins of different foods (from crop breeding to evolution), and ecological and environmental impacts of farming and harvesting practices. Nearly every…

Current reform documents place a strong emphasis on students' understandings of the nature of science (NOS). Interestingly, the importance of this educational outcome is not new and has been agreed upon as important by most scientists and science educators for the past 100 years. Despite numerous attempts, including the major curricular reform…

This contribution describes a new laboratory experience that improves medical students' learning of chronobiology by introducing them to basic chronobiology concepts as well as to methods and statistical analysis tools specific for circadian rhythms. We designed an autorhythmometry laboratory session where students simultaneously played the role…

The Project-Based Learning (PBL) approach enables the student to construct knowledge in his/her own way. Piaget, the founder of constructivism, saw the development of intelligence as a process involving the relationship between brain maturity and individual experience. The technology PBL (TPBL) approach confronts the student with a personal…

As a science subject leader and year 6 teacher in North Bristol, the author has spent the last few months exploring how an interactive whiteboard (IWB) can be used to teach science skills, particularly those that are repeatedly highlighted as problematic, such as analysis and evaluation of evidence. The IWB came with software called…

An experiment was conducted to examine whether perceptual information, specifically the shape of objects, is activated during semantic processing. Subjects judged whether a target word was related to a prime word. Prime-target pairs that were not associated, but whose referents had similar shapes (e.g. LADDER-RAILROAD) yielded longer ''no''…

Numerous findings suggest that non-native speech perception undergoes dramatic changes before the infant' s first birthday. Yet the nature and cause of these changes remain uncertain. We evaluated the predictions of several theoretical accounts of developmental change in infants' perception of non-native consonant contrasts. Experiment 1 assessed…

In the first part of this study, we measured the alignment (relative to segmental landmarks) of the low F0 turning points between the accentual fall and the final boundary rise in short Dutch falling-rising questions of the form "Do you live in [place name]?" produced as read speech in a laboratory setting. We found that the alignment of…

"Hands-on Current Electricity" gives K-8 teachers the opportunity to experience inquiry learning about current electricity by (1) experimenting with current electricity through a variety of activities, (2) discovering preconceived mental models of electricity used to understand their observations, (3) creating new mental models that have greater…

Question-asking is a basic skill, required for the development of scientific thinking. However, the way in which science lessons are conducted does not usually stimulate question-asking by students. To make students more familiar with the scientific inquiry process, we developed a curriculum in developmental biology based on research papers…

In two experiments, students overheard two computer-controlled virtual agents discussing four computer literacy topics in dialog discourse and four in monologue discourse. In Experiment 1, the virtual tutee asked a series of deep questions in the dialog condition, but only one per topic in the monologue condition in both studies. In the dialog…

The food science course developed in Missouri combines basic scientific and mathematics principles in a hands-on instructional format as a part of the family and consumer sciences education curriculum. Throughout the course, students conduct controlled experiments and use scientific laboratory techniques and information to explore the biological…
