In this paper we discuss the role of transduction in the teaching and learning of science. We video-filmed pairs of upper-secondary physics students working with a laboratory task designed to encourage transduction (Bezemer & Kress, 2008). The students were simply instructed to use a hand-held electronic measurement device (IOLab) to find the…

Universities are recognizing the need to prepare graduates to think conceptually and have the ability to take on complex, real-world problems. Strategies to assess conceptual knowledge are limited and often require more time and effort to complete than is accessible for most undergraduate courses. Card sorting is a very broad technique for…

Scientists rely heavily on tree-ring records to better understand climate variability of the past millennium. Tree rings can also be utilized to give students a window into paleoclimate research, the methods scientists use, and the importance of scientific findings. Here, we present five online labs that introduce undergraduate students to the…

Learning how cave formations, such as dripstone, take shape can be a valuable pedagogical tool in chemistry and geochemistry. Grasping the underlying processes requires students to synthesize knowledge of several different topical areas. The activity presented here uses an innovative experiment to connect chemistry concepts with an interesting…

As an aid for teaching phase equilibria to undergraduate students of igneous and metamorphic petrology, we have designed a laboratory exercise that allows them to create a phase diagram from data produced by differential scanning calorimetry. By preparing and analyzing samples of naphthalene and phenanthrene, students acquire hands-on insight into…

Modeling in science has been studied by education researchers for decades and is now being applied broadly in school. It is among the scientific practices featured in the "Next Generation Science Standards" ("NGSS") (Achieve Inc. 2013). This article describes modeling activities in an extracurricular science club in a high…

With the continual growth and demand of online courses, higher education institutions are attempting to meet the needs of today's learners by modifying and developing new student centered services and programs. As a result, faculty members are being forced into teaching online, including Earth and Space science faculty. Online Earth and Space…

A simple mixing of a hot- and cold-water stream at a T-junction was investigated. The main objective was to use mass and energy balance equations to predict mass low rates and the temperature of the mixed stream after the T-junction, and then compare these with the measured values. Furthermore, the thermocouple location after the T-junction and…

Physical World is a one-semester course designed for elementary education majors, that integrates earth science, astronomy, and physics. The course is part of a four-course set that explores science concepts, processes, and skills, along with the nature of scientific practice, that are included in state and national standards for elementary school…

Presents simple laboratory experiments to help students understand the principle of buoyancy and mass balance. Buoyancy experiments can simulate lithospheric mass balance, crustal loading and unloading, and can be used to model differences between the oceanic and continental lithosphere. (MKR)

This article describes an alternative way of testing--a performance assessment--that is different both in process and goals from typical tests, but closer to what teachers believe assessment should be. Teachers who have helped to create, refine, and use this new generation of tests find them valuable because they measure the skills and concepts…

For many, the dominant model of curriculum development in science includes generating a topic, clarifying science content, identifying activities associated with the topic, and figuring out an assessment. Unfortunately, this approach tends to overemphasize activities and underemphasize mastery of science concepts and the process of scientific…

Provides instructions for making telescopes. The design and instruction sheets given to students are provided. (PR)

Describes a "tracing the sun" worksheet combining models with computer programs and classroom discussion. Provides the worksheet including the nine steps of the activity and several discussion questions. (YP)
