Key stage 3 (ages 11-14) in UK schools has been identified as the educational period when pupils rapidly become disengaged with science, largely due to its perceived irrelevance in everyday life and the manner in which it is taught. Until recently, a heavily prescriptive National Curriculum has prevented educationists from devising and delivering…

Use of the "Journalist Method" in science education is described, in which pupils are asked to create short news presentations (we call them news spots) for a fictitious television newscast about science-related issues. The writing of such news spots by cooperative teams of pupils is supported by collections of background information…

Guided inquiry is an instructional technique that requires students to answer a teacher-proposed research question, design an investigation, collect and analyze data, and then develop a conclusion (Bell, Smetana, and Binns 2005; NRC 2000). In this article, the authors describe a guided-inquiry lesson developed through the lesson-study process…

This commentary disagrees with a recent submission (Cheung, D. "J. Chem. Educ. 2009, 86," 514-518) questioning the value of the Le Chtelier principle (LCP). Cheung points out that the LCP fails to predict the proper change in a small set of chemical equilibria. This commentary argues that the LCP has great qualitative utility in correctly…

The question of whether marking speed is related to marking accuracy is important for training examiners and planning realistic marking schedules. We explored marking speed in the context of a past examination for an international biology qualification for 14- to 16-year-olds. Forty-two markers with differing backgrounds experimentally marked 23…

High school girls are bored, disengaged, and stressed in science classes, according to preliminary results of a study led by Northern Illinois University researchers Jennifer Schmidt and M. Cecil Smith. The two professors in the College of Education's Department of Leadership, Educational Psychology, and Foundations studied 244 high school…

The flashlight is a simple device that is composed of a lightbulb, usually two cells connected in series, a housing, a switch, and a reflector for the light. All flashlights essentially use these parts to complete a circuit that converts the stored chemical energy in the cells to light energy. In this lesson, students will take apart an…

Being green means different things to different people. Some suggest that being green means saving energy, not wasting paper towels, going solar, harnessing wind, using less fertilizer, or buying products that are organically grown. Given that being green can mean a lot of things, what does "being green" or "going green" mean to both you and your…

In November 2009, the largest experiment in history was restarted. Its prime target is the Higgs particle--the last remaining undiscovered piece of our current theory of matter. We present a very simple way to introduce this topic to senior secondary school students, using a comparison with the refractive index of light.

One of the main components of teachers' pedagogical content knowledge refers to their use of representation forms. In a similar vein, organizing concepts logically and meaningfully is an essential element of teachers' subject matter knowledge. Since subject matter and pedagogical content knowledge of teachers are tightly connected as categories…

In this study, the learning of science outside the classroom is believe to be an added value to science learning as well as it offers students to interact with the environment. This study presents data obtained from two days' workshop on Lichen as Biological Indicator for Air Quality. The aim of the workshop is for the students to gain an…

This article describes how a university and a museum have worked together to create a "How science works" workshop entitled "What's in our water?" The workshop teaches students about the continuing pollution from a disused coal mine, how the pollution is cleaned up using a state-of-the-art treatment works and how scientists…

Recently, there has been growing emphasis on supporting robust learning within intelligent tutoring systems, assessed by measures such as transfer to related skills, preparation for future learning, and longer term retention. It has been shown that different pedagogical strategies promote robust learning to different degrees. However, the student…

This article uses a narrative approach to start a dialogue about the challenges of teaching blended methods classes that contain traditional and alternative licensure students. Many alternative licensure students enter their methods classes as lateral-entry teachers who must balance their licensure requirements with the demands associated with…

A hybrid (face-to-face and online) professional development (PD) course focused on energy science for middle and high school teachers (N = 47) was conducted using the teaching science as inquiry (TSI) framework. Data from the PD indicates that online opportunities enhanced participation and that the TSI structure improved teachers' inquiry…
