This paper presents the strategies used for effective teaching and skill development in integrated circuit (IC) design using project-based learning (PBL) methodologies. It presents the contexts in which these strategies are applied to IC design courses at the University of South Australia, Adelaide, Australia, and the National Institute of Applied…

We describe a presentation on the science of pizza, which is designed for the general public including children ages 6 and older. The presentation focuses on the science of making and digesting cheese and bread. We highlight 4 major scientific themes: (1) how macromolecules such as carbohydrates and proteins are composed of atoms and small…

Lab notebooks provide students with authentic science experiences as they become active, practicing scientists. Teachers gain insight into students' understanding of science content and processes, while students create a lasting personal resource. This article provides high school science teachers with guidelines for implementing lab notebooks in…

In this integrated inquiry, students in an elementary teaching methods class investigate a real-world problem outside the classroom. The students use the Cognitive Research Trust (CoRT) thinking strategy to find the causes of, impact of, and possible solutions to the problem. They present their findings and then discuss implementation of this…

This study examines the process by which a teacher may be able to answer a question asked in the classroom by using a scientific approach and a simple activity. This article examines a discussion of the question "Is space light or dark?" Priority in the discussion has been given to determining students' preconceptions about the interaction of…

The International Boiling Point Project is an online, collaborative project for students in grades 6-12 in which they investigate the impact of four factors (room temperature, elevation, volume of water and heating device) on the boiling point of water. A detailed procedure is provided for students in order to limit the number of variables…

There is a growing consensus that introductory physics courses should help students develop general scientific reasoning abilities that transform them into lifelong learners, preparing them for careers and citizenship in a rapidly evolving world. Despite the sometimes daunting nature of this challenge, activities developed by various physics…

While not organic in nature, quick-"growing" artificial membranes can be a profound visual aid when teaching students about cellular processes and the chemical nature of membranes. Students are often intrigued when they see biological and chemical concepts come to life before their eyes. In this article, the authors share their approach to growing…

The flight trajectory of a water rocket can be reasonably calculated if the magnitude of the drag coefficient is known. The experimental determination of this coefficient with enough precision is usually quite difficult, but in this paper we propose a simple free-fall experiment for undergraduate students to reasonably estimate the drag…

Both Nette Londo and Carolyn J. B. Melchert took part in "Ah neen dush" ("Why?" in Ojibwe), a three-year professional development program for Head Start teachers on the White Earth reservation. The program, a collaboration between the White Earth Head Start program and the University of Minnesota, was funded by the Office of…

Typically, teachers use tests to evaluate students' knowledge acquisition. In a novel experimental study, we examined whether low-stakes testing ("quizzing") can be used to foster students' learning of course content in 8th grade science classes. Students received multiple-choice quizzes (with feedback); in the quizzes, some target…

A participatory learning approach, combined with both a traditional and a competitive assessment, was used to motivate students and promote a deep approach to learning biochemistry. Students were challenged to research, author, and explain their own multiple-choice questions (MCQs). They were also required to answer, evaluate, and discuss MCQs…

Based on a three-year-long ethnography of the hobby of model rocketry, I present a practice-centered theory of interest relationships--that is, the pattern of long-term, self-motivated engagement in open-ended practices that has been theorized under the concept of "individual interests". In contrast to extant theories of individual interests, in…

The discovery or re-construction of scientific explanations and understanding based on experience is a complex process, for which school learning often uses shortcuts. On the basis of the example of analyzing real seismic measurements, we propose a computer-facilitated collaborative learning scenario which meets many of the requirements for…

A priority for all biology teachers must be for students to leave the classroom with a broad knowledge and understanding of science. Students need to be critical of science, analyze science, and relate new science knowledge to their daily lives. Unfortunately, many students are not reaching this goal. One strategy for making science laboratories…
