Presents examples of the types of investigations which exploit the tools now commonly featured in data-logging software. Emphasizes the importance of designing tasks that encourage pupils to think about the data and the principles which underpin worthwhile data-logging tasks. (Author/ASK)

Presents an activity that explores the derivation of Pi. Involves students taking a constructivist role by collecting data, making conjectures, and using the data to construct graphs and tables and discourse about appropriate algebraic representations. Uses the computer as an instructional aid to enable students to view the data in a variety of…

Presents an investigation, applicable for grades 3-6, that focuses on the concept of randomness and encourages children to conjecture and to conduct experiments which verify or contradict their intuitions. Involves using hands-on explorations, collecting data, and drawing conclusions on the basis of the information. (JRH)

Describes the Inquiry "I" which is designed as a learning tool for scientific inquiry. Explains the steps of prior knowledge, logical argument, experimental design, procedure, data collection, data transformation, results, and new knowledge. Uses guided and open inquiry approaches. (YDS)

Presents activities that center on the excitement of going back to school by collecting and analyzing data and exploring probabilities. Contains reproducible student worksheets. (MKR)

Explains the typical design, operation, and calibration of a traditional psychrometer. Presents the method utilized for this class project with design considerations, calibration techniques, remote data sensing schematic, and specifics of the implementation process. (JJK)

Recommends that teachers avoid cookbook-type exercises and predescribed protocols for laboratory work and instead engage students in research that can teach critical thinking, problem solving, and analytical skills. (DDR)

Describes a process of data collection with young children using the outdoors as a mathematical context. The process of data collection and processing introduces children to more abstract mathematics as they sort and classify data, create graphs, compare datasets, examine patterns, and interpret graphical representations. (ASK)

Presents an experiment on collecting data while measuring the dissolved-oxygen levels in Thames River tap water straight from the water mains and dissolved-oxygen levels in rainwater containing Hornwort water weed over 24 hours. (Author/ASK)

Outlines a class project in which students explore characteristics of paper towels and paper towel advertising. Students design a variety of experiments related to paper towels and their claims. Provides four activities. (DDR)

Addresses the use of the Internet for telecollaboration, or communicating and working with others in different locations, in the elementary social studies classroom. Focuses on a set of activity structures to help teachers design curriculum-based, telecollaborative activities. Provides examples of telecollaborative activities. (CMK)

Research is the planned collection, selection, and processing of information that typically takes three forms--historical, descriptive, or experimental. Historical research seeks to uncover facts with respect to events that have already happened, descriptive research seeks to uncover facts with respect to the current scene of events, and…

This report discusses an iterative methodology for logical database design (LDD). The methodology includes four phases: local information-flow modeling, global information-flow modeling, conceptual schema design, and external schema modeling. These phases are intended to make maximum use of available information and user expertise, including the…

One of a series of instructional booklets designed to introduce adult education program planners to the basic concepts integral to and alternative strategies for conducting needs assessments, this instructional booklet deals with determining how to summarize information. Described first is the relationship of the process of determining how to…

Four types of values education approaches for use in teaching in high school biology classes are described. The approaches include moral development, values clarification, action learning, and analysis. Inculcation is mentioned but not discussed because the author feels that it does little to help develop values. (SA)
