An activity in which students establish criteria outlining what constitutes wasted paper, calculate averages, and compute the number of trees needed to produce a measured amount of wasted paper is described. The mathematics and science concepts, objectives, rationale, content overview, lesson outline, and extensions are included. (KR)

Examines the influence of two factors of the process of graphing on rural students' (n=93) ability to comprehend kinematics graphs on constant velocity events. Students exhibited difficulty in constructing and comprehending graphs of derived variables and were unaware of their own graphing skills deficiencies. (34 references) (MDH)

This case study characterizes the inscriptional practices demonstrated by seventh graders, particularly their use of data tables and graphs, in an inquiry-based learning environment. Using a naturalistic approach, we collected multiple sources of data during an 8-month instructional unit that emphasized water quality and relevant concepts. The…

This study explored some practical issues for single-case researchers who rely on visual analysis of graphed data, but who also may consider supplemental use of promising statistical analysis techniques. The study sought to answer three major questions: (a) What is a typical range of effect sizes from these analytic techniques for data from…

The paper describes the use of a spreadsheet in a mathematics teacher education course. It shows how the tool can serve as a link between seemingly disconnected mathematical concepts. The didactical triad of using a spreadsheet as an agent, consumer, and amplifier of mathematical activities allows for an extended investigation of simple yet…

This practicum was designed to improve the research and communication skills of eighth-grade students with the integration of technology, mathematics, and science when doing real-experience problem solving. Four units were developed that related the use of technology to skills that are also used in gathering, organizing, and manipulating research…

The two primary college admission test batteries given in Nevada are the American College Test (ACT) and the tests prepared by the College Board, the Scholastic Aptitude Test (SAT) and the Test of Standard Written English (TSWE). This report provides an overview of the tests and major trends in Nevada for 1988. These tests apply to a small portion…

The two primary college admission test batteries given in Nevada are the American College Test (ACT) and the tests of the College Board, the Scholastic Aptitude Test (SAT) and the Test of Standard Written English (TSWE). This report provides an overview of the two tests and major trends pertinent to Nevada for 1989; however, because of the small…

Statistical information is presented in a series of corresponding graphs and tables reflecting important trends in public elementary and secondary education in Michigan. The report covers the following major areas: (1) pupils, including student characteristics and enrollment (37 tables and graphs); (2) outcomes of education, including achievement…

A study was done to determine the extent to which children in public high and low poverty schools receive similar services and levels of supports, and whether public schools receiving Chapter 1 assistance appear to have more services and support than do similar non-Chapter 1 schools. The study used data from the base year Schools and Staffing…

One potential approach to the authentic assessment of what students know and can do in science is concept mapping. A concept map is a graph consisting of nodes representing concepts and labeled lines denoting the relation between a pair of nodes (concepts). The external concept map constructed by the student is interpreted as representing…

Eleven tables and five graphs present statistical data concerning the Tests of General Educational Development Program (GED Testing Program) in 1990. Data for each state and Canadian province are included. The tables present data on the following topics: testing volumes (i.e., number of people tested), percentage of people tested by age group,…

Prepared for the California Community Colleges' 1991 Board of Governors retreat, this paper discusses several statewide trends that have implications for California's community colleges. The paper is designed to serve as background material for the development of the Board of Governors' 1991-92 basic agenda. Material covered in the report updates…

A unit of study that introduces measuring as a way of collecting data is presented. Suitable for students in grades 3 and 4, it provides a foundation for further work in statistics and data analysis. The investigations may extend from one to four class sessions and are grouped into three parts: "Introduction to Measurement"; "Using Standard…

This guide describes 20 learning activities that can be used with elementary school students on the topic of probability and statistics. These activities have been developed using the mathematics laboratory approach. This publication is designed to serve as a stimulant to encourage teachers to open their minds and employ their imagination in…
