Studies evaluating the graphics in science textbooks have recommended that teachers use eye-catching visuals to reinforce student learning objectives. Similarly, the "Next Generation Science Standards" (NGSS Lead States 2013) suggest that science teachers use visuals to teach English Language Learners (ELLs). However, little research has…

Instructions are given for building physical scale models of ordered structures of B-form DNA, protein [alpha]-helix, and parallel and antiparallel protein [beta]-pleated sheets made from colored computer printouts designed for transparency film sheets. Cut-outs from these sheets are easily assembled. Conventional color coding for atoms are used…

Textbook companies are increasingly including larger numbers of animations as complementary resources for students and teachers. Are all animations useful as teaching tools? The answer is no. Animations can be useful for communicating dynamic events and processes but only when specific rules are followed. The authors review the important…

Within the framework of cognitive learning theories, instructional design manipulations have primarily been investigated under tightly controlled laboratory conditions. We carried out two experiments, where the first experiment was conducted in a restricted system-paced setting and is therefore in line with the majority of empirical studies in the…

The number of experimentally derived structures of cellular components is rapidly expanding, and this phenomenon is accompanied by the development of a new semiotic system for teaching. The infographic approach is shifting from a schematic toward a more realistic representation of cellular components. By realistic we mean artist-prepared or…

Presents the LOGO computer language as a source to experience and investigate scientific laws. Discusses aspects and uses of LOGO. Lists two LOGO programs, one to simulate a gravitational field and the other projectile motion. (MVL)

Describes the use of NASA Spacelink Computer Information Service for Educators to obtain instructional materials and ideas for classroom demonstrations. Uses the free-fall concept of zero gravity as an example. Provides NASA Spacelink contact information. (JRH)

Investigated the overall effectiveness of and use of animation/graphics in "Introduction to Organic Chemistry" computer programs on student achievement and attitudes (n=approximately 400). Results indicate that although materials were effective animation sequences, they did not have an effect on student test scores. (JN)

These materials were designed to be used by life science students for instruction in the application of physical theory to ecosystem operation. Most modules contain computer programs which are built around a particular application of a physical process. The report describes design standards for the computer programs. They are designed to be…

These materials were designed to be used by life science students for instruction in the application of physical theory to ecosystem operation. Most modules contain computer programs which are built around a particular application of a physical process. PRNT3D is a subroutine package which generates a variety of printed plot displays. The displays…

Provides a listing of a software graphics program that investigates the law of reflection and Snell's law of refraction. Written in BASIC for the Apple II personal computer. (MVL)

Describes three software packages: (1) "MacMendeleev"--database/graphic display for chemistry, grades 10-12, Macintosh; (2) "Geometry One: Foundations"--geometry tutorial, grades 7-12, IBM; (3) "Mathematics Exploration Toolkit"--algebra and calculus tutorial, grades 8-12, IBM. (MVL)

Discusses chaotic behavior (movement) in a nonlinear system using LOGO programs. Presents several examples with program listings. (MVL)

Considers the development of a computer program for interactive, screen-oriented problem solving. Provides theoretical background and program development to determine internal energy, heat capacity, and entropy. Lists the program written in BASIC for Apple II computers. (MVL)

Notes two uses of computer spreadsheets in the chemistry classroom. Discusses the general use of the spreadsheet to easily provide changing parameters of equations and then replotting the results on the screen. Presents a molecular orbital spreadsheet calculation of the LCAO-MO approach. Supplies representative printouts and graphs. (MVL)
