Polar research plays a vital role in developing our understanding of Earth's climate system. It is intrinsically interdisciplinary, lending itself to integration into existing undergraduate courses. Here we explore introducing undergraduates to polar research through computational guided inquiry (CGI) modules taught in a variety of courses and…

A "Framework for K-12 Science Education" identified eight practices as "essential elements of the K-12 science and engineering curriculum" (NRC 2012, p. 49). Most of the practices, such as Developing and Using Models, Planning and Carrying Out Investigations, and Analyzing and Interpreting Data, are well known among science…

The application of technology in classroom settings has equipped educators with innovative tools and techniques for effective teaching practice. Integrating digital technologies at the elementary and secondary levels helps to enrich the students' learning experience and maximize competency in the areas of science, technology, engineering, and…

Significant information on the relative thickness of plutons, the structure of poorly exposed or concealed magnetic units, and possible evidence of mineralized ground are discussed. The techniques used to produce images that reveal the new information are described. A list of 34 references is included. (CW)

Outlines an in-depth case study of teachers' use of image processing in biology, earth science, and physics classes in one high school science department. Explores issues surrounding technology implementation. Contains 21 references. (DDR)

Presented is a description of a BASIC program to be used on an IBM microcomputer for calculating and plotting synthetic seismic-reflection traces for multilayered earth models. Discusses finding raypaths for given source-receiver offsets using the "shooting method" and calculating the corresponding travel times. (Author/CW)

The Texas Teacher Internship Program (TTIP) is a competitive program for science, technology and mathematics teachers who serve as summer interns at industry and university sites in order to experience real world applications of the subjects they teach. This document contains curriculum implementation plans developed by the teachers to illustrate…

Presented are 29 science activities for secondary school science instruction. Topic areas include botany, genetics, biochemistry, anatomy, entomology, molecular structure, spreadsheets, chemistry, mechanics, astronomy, relativity, aeronautics, instrumentation, electrostatics, quantum mechanics, and laboratory interfacing.

Because density is unobservable and must be inferred from knowledge about weight and size, it is a difficult concept to teach and learn. Even after traditional instruction, many students still have an undifferentiated concept that mixes characteristics of both weight and density. In this study, researchers tested the effectiveness of a unit they…

Two classroom studies, one conducted in the spring of 1985 and the second in the spring of 1986, showed that many high school students do not differentiate between heat and temperature; instead, they have a single concept that contains some of the features of heat and some of the features of temperature. Because the distinction between these two…

The concept of the density of a material has an important role in elementary and secondary school science curricula, but it is a difficult concept to grasp. This project explores why this should be and whether there are some simpler, more accessible notions which can serve as the basis for building a concept of density in students' minds during…

Describes a summer institute for elementary secondary science teachers held at the University of California, Irvine, which is designed to update and refine the scientific knowledge of the teachers and to build a scientific foundation for crossover teachers who are teaching without an adequate science background.

Density is the first intensive physical quantity students encounter that can be understood in terms of an underlying model, the particulate theory of matter. Learning about density provides students with explanations for a range of phenomena such as sinking and floating, and changes of state. Teachers report, however, that density is a difficult…

The UNESCO SchoolNet project, "Strengthening ICT in Schools and SchoolNet Project in ASEAN Setting", was initiated to assist teachers to integrate ICT into teaching and to facilitate participation of teachers and students in the Asia-Pacific region in SchoolNet telecollaboration activities. The project was launched in July 2003 and…
