Describes the development of occupational standards for technicians in education and highlights the main aspects of the work. Explains the importance of learning as much as possible about technicians' work so that emerging occupational standards are both accurate and enabling. (DDR)

Describes a physics experiment investigating temperature prediction and the relationship between the physical properties of heat units, melting, dissolving, states of matter, and energy loss. Details the experimental setup, which requires hot and cold water, a thermometer, and ice. Notes that the experiment employs a deliberate counter-intuitive…

Outlines the components of a technology center that supports over 5,000 students per semester. Discusses instructional computing environment and consistent student interface, management system, gradebook, classroom, networking, and application software. Concludes that the integration of computer-based instruction, multimedia presentations,…

Describes a course, Chemistry for Elementary Education Majors, collaboratively planned and taught by chemistry and teacher education faculty. Discusses the instructional bases of the course, the audience, themes and activities in the course, course expenses, student learning, and challenges for the future. Lists the course schedule with lab and…

Presents a numerical simulation of a simple food chain together with a set of mathematical rules generalizing the model to a food web of any complexity. Discusses some of the model's interesting features and its use by students. (Author/JRH)

Describes a lab that introduces agarose electrophoresis techniques and basic information on proteins to middle school and high school students. Insists that, built around a scenario in which students must solve a crime, the lab has real-world applications that should spark student interest. (KHR)

Since young children are natural scientists, early childhood educators should view science instruction as an ongoing part of the total curriculum, easily woven into daily activities and routines. Established standards for science literacy reinforce the idea that children best learn science through hands-on, meaningful, and relevant activities.…

Reports on Project 2 from the Evidence-based Practice in Science Education (EPSE) Research Network. In this project, teachers and researchers worked collaboratively on the design of three short teaching sequences on electric circuits. (DDR)

Introduces the Apple Ocean activity which teaches about the diminishing natural resources of the earth including drinkable water, habitable land, and productive areas while working with fractions, ratios, and proportions. (YDS)

Outlines activities that encourage students' talking, reading, and writing about science in a way that supports both inquiry-based science instruction and a student-centered approach to literacy. Notes that talk is very important to science learning in the elementary classroom. Describes how writing "ecomysteries," dialogue journals, and grant…

Describes the five-cups activity in which students explore materials in the cups. Discusses the effects of this activity on students' understanding of the nature of evidence and the quality and evaluation of that evidence. Includes test results during class and overnight. (KHR)

Presents a laboratory exercise on spicy food and body temperature that introduces the scientific method to introductory biology students. Suggests that when students perform their own experiments which they have developed, it helps with their understanding of and confidence in doing science. (Author/SOE)

Describes the "I Wonder" project, which uses student questions to teach and enhance the science curriculum. Students kept journals to reflect upon classroom activities and document solutions to science and mathematics problems, and came up with the topics they wanted to investigate in the form of a question beginning with "I wonder". Includes…

Describes use of a sundial to study Earth's orbit and time. Covers construction of sundial, exploration phase, introduction of concept of time as determined by the position of the sun in relation to the observer's meridian, comparison of sundial time and wristwatch time, longitudinal corrections, introduction of orbital corrections, and further…

Describes the "ABCD" model for integrating spreadsheets into elementary science instruction, which consists of four steps: analyzing the software and curriculum; brainstorming connections between parts of the software and the content areas; creating connections among the curriculum, the brainstorming information, and noncomputer classroom…
