We discuss strategies for the general solution of single-step 1D constant acceleration problems. In a slightly restricted form, these problems have five variables (?"x," "v[subscript 0]," "v," "a" and "t") and two independent equations, so three variables must be given to solve for the other two,…

Learning about statistics is a lot like learning about science: the learning is more meaningful if you can actively explore. This ninth installment of "Explorations in Statistics" explores the analysis of ratios and normalized--or standardized--data. As researchers, we compute a ratio--a numerator divided by a denominator--to compute a…

This article provides an instructional approach to helping students generate open-inquiry research questions, which the authors call the "open-inquiry question template." This template was created based on their experience teaching high school science and preservice university methods courses. To help teachers implement this template, they…

A brief outline of the known or presumed initial environment and its changes over time is given to observe the connection between the origin and evolution of the metallomes of cells to the environment and its changes. The connection to the environment leads from the abundance and environmental availability of the elements and therefore gives an…

Described is an activity designed to make the concepts of experimentation, independent variables, and dependent variables easy to understand by using observable characteristics of several rods to illustrate these concepts. (DS)

Reports on a study of engineering students at the Technical University of Norway (NTH) which focuses on the factors that influence women to become students at NTH. Compares study results to national and international studies concerning women and work. (ML)

Validity of using time and behavior as predictors of learning was tested by collecting detailed visitor behavior and time expenditure while interacting with a participatory museum exhibit. Data from 12- and 13-year-olds (N=63: 32 males, 31 females) support the feasibility of using these predictors. Learning was measured using a 14-item test.…

Reports on a study conducted to determine whether a common relationship exists for faculty size in U.S. engineering colleges. Suggests that an index of normative loading can possibly be established. (RT)

To understand the impact of all of the various science and mathematics improvement initiatives and to make them more effective in the future, it is important to be able to monitor the condition of science and mathematics education in the schools. This report presents a review of the information and data currently available; it is a preliminary…

Twelve articles present excerpts from several national reports of countries participating on the Second International Science Study (SISS) of the International Association for the Evaluation of Educational Achievement. The SISS examined science achievement and its correlates in participating countries and studied trends from 1970 through the…
