Offers a group exercise for teaching students how to achieve consensus concerning rank order. Explains that students are assigned to rank the incidence of animals biting their own species in New York City. Reports that the teacher chooses a group member to explain the group's ranking. Identifies evaluation methods for the exercise. (SG)

Describes the use of investigations for the purpose of assessment, teaching, and learning. Lists types of questions that can be included in investigations. Explains how to write an investigation and provides some examples. (ASK)

The difference between mathematical "investigations" and "investigating," used in two different British reports, is discussed. Investigations means an extensive project or extended exploration into a mathematical problem or topic. Investigating is promoted as an ongoing teaching method. (MNS)

Reports on rich mathematical activities that integrate different mathematics strands and learning. Describes how to introduce the task and the classroom setting, set up the task, and continue the investigation. Presents student work samples. (ASK)

Portions of the Cockcroft Report which seem confusing are discussed. The connections among problems, applications, and investigations are considered in sections on being a mathematician; open is in the mind; assumptions, rules and patterns; and learning not to be anxious. (MNS)

Although traditional instructional methods and textbooks mitigate against it, investigation can be a viable alternative strategy in the geometry classroom. Many theorems in geometry, such as Euclidean space, lend themselves easily to student experimentation. (Author/SJL)

Defines and supports investigative mathematics for schools. Presents several results of an investigation of Fermat's Last Theorem. (PK)

Presents a learning cycle lesson plan in which students investigate the question of how cells divide. Students use microscopes to explore actual plant root and stem tissues to generate and test hypotheses to answer the question. Includes teacher material, student material, and teaching tips. (MDH)

What types of instructional experiences help K-8 students learn science with understanding? What do science educators, teachers, teacher leaders, science specialists, professional development staff, curriculum designers, and school administrators need to know to create and support such experiences? "Ready, Set, Science!" guides the way with an…

Suggests structured investigations as a method of teaching mathematics to preservice elementary school teacher. Presents an example problem that asks students to determine the maximum number of regions that can be created by connecting any two points around the circumference of a circle. (MDH)

Proposes the use of metal cans to create science experiments that motivate students to investigate the scientific concepts of electricity, magnetism, heat, inertia, and sound transmission. Describes several experiments using cans in which students explore the properties of metal. (MDH)

Suggested are investigations of rational numbers and their decimal representations where a computer generates the data for explorations. Conjectures and two program listings are included. (MNS)

Students experience the distinction between observable fact and scientific theory by taking a critical look at how spaghetti can be sucked up into the mouth. A demonstration shows that air is needed to suck up the spaghetti but that the scientific explanation is not as simple. (MDH)

Discusses the development of a student's ability to control experiments as an important aim of modern science curriculum materials. Argues that most curriculum developers offer only a simplistic method of controlling variables. Suggests ways to enhance the development of variable control within the framework of student experiments. (TW)

Describes the use of cross-age tutoring in which sixth-grade students are used to teach first-grade students about plants. Provides a list of praise words used by the sixth graders and discusses the mutual benefits received by the students. (MDH)
