Learning about states of matter is fun and exciting when students, acting as water molecules, role-play moving from a solid to a liquid to a gas. The 5-E lesson plan model provides the framework for this activity, ensuring that students actively engage in inquiry science while creatively constructing knowledge. (Contains 2 figures.)

Interactive simulations are entering mainstream science education. Their effects on cognition and learning are often framed by the legacy of information processing, which emphasized amodal problem solving and conceptual organization. In contrast, this paper reviews simulations from the vantage of research on perception and spatial learning,…

Current models of bilingualism (e.g., BIA+) posit that lexical access during reading is not language selective. However, much of this research is based on the comprehension of words in isolation. The authors investigated whether nonselective access occurs for words embedded in biased sentence contexts (e.g., A. I. Schwartz & J. F. Kroll,…

The activation of cAMP-responsive element-binding protein (CREB)-dependent gene expression is thought to be critical for the formation of different types of long-term memory. To explore the consequences of chronic enhancement of CREB function on spatial memory in mammals, we examined spatial navigation in bitransgenic mice that express in a…

Evaluating the structural quality of arguments is a skill that is important to students' ability to comprehend the arguments of others and produce their own. The authors examined college and high school students' ability to evaluate the quality of 2-clause (claim-reason) arguments and tested a tutorial to improve this ability. These experiments…

Recent emphasis on the science of food and cooking has been observed in our popular literature and media. As a result of this, a new non-science majors course, The Science of Food and Cooking, is being taught at our institution. We cover basic scientific concepts, which would normally be discussed in a typical introductory chemistry course, in the…

Over the course of three rounds of consecutive funding, the National Science Foundation (NSF) invested in the Traveling Exhibits at Museums of Science (TEAMS) collaborative. Since 1996, the TEAMS collaborative museums have developed traveling exhibitions and related education materials to circulate through each other's museums, and then more…

In this study the effect of a stimulus-stimulus pairing procedure was used as part of a clinical investigation to increase vocalizations for two young children diagnosed with autism. This procedure involved pairing a vocal sound with a preferred stimulus (e.g., toy) to condition automatic reinforcement. In addition, this study assessed the effects…

A model for engaging undergraduates in cutting-edge experimental nuclear physics research at a national user facility is discussed. Methods to involve students and examples of their success are presented. (Contains 2 figures and 3 tables.)

Laboratory sessions offer students an opportunity to develop creative problem-solving skills and to better understand the nature of the scientific process through hands-on learning. Unfortunately, traditional procedures are often written in such detail, they require students to do little more than follow step-by-step directions. Under those…

The Celsius and Kelvin temperature scales, we tell our students, are related. We explain that a change in temperature of 1 degree C corresponds to a change of 1 Kelvin and that atoms and molecules have zero kinetic energy at zero Kelvin, -273 degrees C. In this paper, we will show how students can derive the relationship between the Celsius and…

Our school has a very small budget for equipment. So finding a gem like a conservation of momentum lab requiring only basic materials ("TPT", October 2005) adds a great deal to my physics course. In this lab, a "shooter" nickel makes a non-head-on collision with a stationary "target" nickel. Students measure the distance each nickel slides after…

Iconicity--resemblance between a symbol and its referent--has long been presumed to facilitate symbolic insight and symbol use in infancy. These two experiments test children's ability to recognize iconic gestures at ages 14 through 26 months. The results indicate a clear ability to recognize how a gesture resembles its referent by 26 months, but…

A force spectroscopy model experiment is presented using a low-cost tensile apparatus described earlier. Force-extension measurements of twisted rubber bands are obtained. They exhibit a complex nonlinear elastic behaviour that resembles atomic force spectroscopy investigations of molecules of titin, a muscle protein. The model experiments open up…

The study focused on the effects of the CAL system constructed via cognitive conflict of decimal numbers for the sixth graders. The purpose of the system is to gauge decimal concepts of students. When students entertain misconceptions or misleading ideas, the system will in accordance with the types of the wrong answer generate appropriate…
