This exercise integrates the infrared unknown identification ("IR-ID") experiment common to most organic laboratory syllabi with computer molecular modeling. In this modification students are still required to identify unknown compounds from their IR spectra, but must additionally match some of the absorptions with computed frequencies they…

SDS-PAGE is a simple, rapid technique that has many uses in biochemistry and is readily adaptable to the undergraduate laboratory. It is, however, a technique prone to several types of procedural pitfalls. This article describes the use of SDS-PAGE to determine the subunit molecular mass and composition of yeast alcohol dehydrogenase employing…

This qualitative research study focused on the eight bilingual, content area high school teachers implementing Project SOL (Secondary Online Learning) in Southern California during the 2008-2009 school year. It documents their effort to integrate an online curriculum from the "Colegio de Bachilleres" in Mexico obtained through the UCLA…

Case-study descriptions of secondary and middle school classrooms in diverse contexts provide examples of how teachers implement connected classroom technology to facilitate formative assessment in science instruction. Connected classroom technology refers to a networked system of handheld devices designed for classroom use. Teachers were…

Describes the formalization of a minicourse in which middle school students would meet once a week for one hour to critique and redesign an embryonic website, investigate and document their environment, and figure out ways to incorporate into the website what they saw, wondered about, and learned. Evaluates the effectiveness of the minicourse. (SG)

Outlines the object-process approach to designing and analyzing studyware in organic chemistry. Object-process diagrams are used to visualize the relationships between objects and processes within a system. (Author/MKR)

Reports on what science teachers are doing with instructional technology (IT) in science and what software they are using to do it with. Includes examples of teachers using data logging, palmtop computers, word processing, spreadsheets, and CD-ROMs. (MKR)

An important challenge faced by many teachers as they involve students in science investigations is measuring (assessing) students' progress. Our detailed requirements analysis in a particular school district led to the idea that what teachers need most are ways to increase the quality of the information they have about what students know and can…

In 1990, a group of geologists discovered a large number of shatter cones in southwestern Montana. Shatter cones are a type of metamorphosed rock often found in impact structures (the remains of a crater after a meteor impact and years of Earth activity). Scientists have discovered only 168 impact craters around the world. If rocks could talk,…

This article discusses the challenges that bioinformatics education is facing and describes a bioinformatics course that is successfully taught at the California State Polytechnic University, Pomona, to the fourth year undergraduate students in biological sciences, chemistry, and computer science. Information on lecture and computer practice…

In this article, we present the results of a qualitative research project on the effect of motion analysis activities in a Video-Based Laboratory (VBL) on students' understanding of position, velocity and frames of reference. The participants in our research were 48 pre-service teachers enrolled in Education Departments with no previous strong…

We investigate short-term learning from hints and feedback in a Web-based physics tutoring system. Both the skill of students and the difficulty and discrimination of items were determined by applying item response theory (IRT) to the first answers of students who are working on for-credit homework items in an introductory Newtonian physics…

While most would agree wholeheartedly with the benefits of getting students out more, there are numerous challenges in doing so, ranging from shrinking budgets to a standardized test-driven scholastic environment. However, the Division of Interpretation in Yellowstone National Park has gone to great lengths to provide resources for the classroom…

This article aims at discussing how Dynamic Decision Network (DDN) can be employed to tackle the challenges in modeling temporally variable scientific inquiry skills and provision of adaptive pedagogical interventions in INQPRO, a scientific inquiry exploratory learning environment for learning O'level Physics. We begin with an overview of INQPRO…

The authors of this study document one middle school classroom in an attempt to understand how inquiry learning, supported with technological tools, can provide students with opportunities to develop ownership of science content knowledge. Case study and collaborative teacher researcher methods were utilized to document the implementation of a…
