In this paper we demonstrate that "lesson study" may be adapted from its primary use as a professional development strategy for use as a research strategy, especially to identify principles of good lesson design. We report on a project undertaken in two Australian secondary schools where lesson study research was used to investigate the…

The American Recovery and Reinvestment Act (ARRA) provides several funding opportunities that can assist states in designing, developing, and implementing statewide education longitudinal data systems. These new and enhanced information systems will enable states to track student progress within and across the secondary and postsecondary education…

Presents examples that illustrate how spreadsheets can be used to ask and answer all sorts of scientific questions given suitable automation of useful spreadsheet procedures. Examples include data exploration, data analysis, project presentation, simulations, and students writing their own models. (Author/JRH)

Presents an experiment that investigates the temperature of tungsten filaments using a car headlamp. Uses a spreadsheet program that facilitates extensive data manipulation. Gives students an awareness of the many mathematical techniques used in data analysis. (Author/JRH)

Looks back over a number of exploratory studies that have researched young children's construction of meaning for graphs produced from data entered into spreadsheets. Discusses children's use of normalizing, an activity in which children 'correct' data towards some perceived norm. (Author/MM)

Describes the role of an instructional sequence and two accompanying computer-based tools in supporting students' developing understandings of statistical data analysis. Documents the emergence of the sociomathematical norm of what counts as a mathematical argument in the context of data analysis. (Author/MM)

Discusses the use of databases in order to encourage students to test hypotheses, generate conjectures, and interpret trends in data. Describes "Storybook Project" in which a survey of gender bias in children's storybooks is conducted. Grass database is used for data gathering and students interpret and discuss their results. (ASK)

Discusses the important role of graphs in conveying scientific information and the use of computer software in amplifying the value of graphs as tools for scientific investigation. Topics discussed include: skills required for analyzing and interpreting graphs, software design, and teaching and learning strategies. (JRH)

Summarizes 19 papers presented at the Fourth International Conference on Teaching Statistics held in Morocco, July 1994. Papers presented were in five categories: (1) empirical studies on students' conceptions; (2) theoretical papers on teaching and learning; (3) assessment; (4) using computers in teaching probability and statistics; and (5) data…

Explains how the graphing calculator can be used in simulations of physics experiments and how its use for plotting graphs requires a shift in emphasis from obtaining an experimental result to evaluating that result. (DDR)

Describes when and how to carry out many of the most common statistical tests including mean, standard deviation, confidence limits, correlation, regression, t-test, Chi square test, and ANOVA. Uses Excel to perform these operations. (DDR)

Presents a lesson for high school students in which they collect and analyze data using questions from the actual Census 2000 long form and then participate in a simulation of a local planning council meeting to consider the short- and long-term community needs. Includes the Census 2000 long form. (CMK)

Describes an activity in which students use data analysis and mathematical modeling to obtain insight into a geometrical question. Explores a simple case of the isoperimetric inequalities. (KHR)

Presents strategies that utilize graphing calculators and computer software to help students understand the concept of minimizing the squared residuals to find the line of best fit. Includes directions for least-squares drawings using a variety of technologies. (DDR)

Describes an exercise, step-by-step, for developing critical thinking while exposing students to electronic-data skills. Argues that the exercise enhances critical thinking by forcing students to deal with issues of data definition, collection, and interpretation, and by providing an active learning experience with real-world data.
