Science teaching and learning can be made both engaging and student-centered using pedagogical, computer-based learning tools. We have developed self-paced interactive problem-solving tutorials for introductory physics. These tutorials can provide guidance and support for a variety of problem-solving techniques, as well as opportunities for…

The goal of the two Power of Data (POD) projects was to increase science, technology and math skills through the implementation of project-based learning modules that teach students how to solve problems through data collection and analysis utilizing geospatial technologies. Professional development institutes in two formats were offered to…

A causal explanation in biology focuses on the mechanism by which a biological process is brought about, whereas a teleological explanation considers the end result, in the context of the survival of the organism, as a reason for certain biological processes or structures. There is a tendency among students to offer a teleological explanation…

This article discusses the revised Northern Ireland Curriculum which will be fully implemented across all key stages by June 2010. The revision gives schools greater flexibility with statements of minimum entitlement for subject strands replacing detailed subject programmes of study. Teachers are encouraged to promote a cross-curricular approach…

This article explores the development of observation in scientific and everyday contexts. Fundamental to all scientific activity, expert observation is a complex practice that requires the coordination of disciplinary knowledge, theory, and habits of attention. On the surface, observation appears to be a simple skill. Consequently, children may be…

A case study is an excellent way to help students think like scientists as they work to solve a dilemma. This article describes a case study of elk in Yellowstone National Park. Students read short narratives, based on scientific research data, about the puzzling question of why some elk live substantially longer than others in certain areas of…

In contrast to mainstream science, paranormal phenomena have the effect of "blowing things up" because they offer big, grand, gorgeous images that even the uninitiated can grasp and thrill to at first blush. It makes little difference if one has never seen Bigfoot, an alien, or a human clone. There are those who claim they have, and…

Teaching "scientific method" has long been a regular part of science education, and many curriculum standards call for it. But it has run into a variety of criticisms, which add up to the charge that it conveys an unrealistic and unappealing view of science. In this article, the authors discuss how science really works and provide different ways…

A laboratory activity for an upper-level undergraduate course in instrumental analysis has been created around LabVIEW. Students learn rudimentary programming and interfacing skills during the construction of a fluorimeter assembled from common modular components. The fluorimeter consists of an inexpensive data acquisition module, LED light…

While looking for labs for his pre-engineering class, the author came across an idea for a marine engineering project from the Future Scientists and Engineers of America website. The author thought the lab looked fun, and it was not too expensive. These were two important criteria as he chose labs for the class. Another important criteria he had…

This study was conducted to explore the effectiveness of conceptual change oriented instruction over traditional instruction on students' understanding of acids and bases concept. Besides, effects of gender difference and science process skills on students' understanding of acids and bases were also investigated. Analysis of the results showed…

The European Association for Astronomy Education (EAAE), in collaboration with the Bibliotheca Alexandrina of Egypt and the participation of schools from all around the world, performed the Eratosthenes experiment on 21 June 2010. This activity has been selected as one of the finalists in the 11th international prize organized by Ciencia en…

Background: Problem-based learning (PBL) is a teaching approach working in cooperation with self-learning and involving research to solve real problems. The first law of thermodynamics states that energy can neither be created nor destroyed, but that energy is conserved. Students had difficulty learning or misconceptions about this law. This study…

Educators in many disciplines recognize interdisciplinary teaching as effective for student learning. This article provides a model for developing an interdisciplinary literacy and science study with states of water as the core scientific study with corresponding literacy strategies. Authors have included suggestions for children's literature as…

Researchers describe the need for students to have multiple opportunities and social interaction to learn about the differences between observation and inference and their role in developing scientific explanations (Harlen 2001; Simpson 2000). Helping children develop their skills of observation and inference in science while emphasizing the…
