Research that has explored students' interpretations of graphical representations has not extended to include how students apply understanding of particular statistical concepts related to one graphical representation to interpret different representations. This paper reports on the way in which students' understanding of covariation, evidenced…

At their core, Intelligent Tutoring Systems consist of a student model and a policy. The student model captures the state of the student and the policy uses the student model to individualize instruction. Policies require different properties from the student model. For example, a mastery threshold policy requires the student model to have a way…

As the availability of high-throughput data-collection technologies, such as information-sensing mobile devices, remote sensing, internet log records, and wireless sensor networks has grown, science, engineering, and business have rapidly transitioned from striving to develop information from scant data to a situation in which the challenge is now…

This paper reports on the final phase of a three-part study on the status of instructional supervision within several New York City public schools. In the first parts of the study the researchers found, through extensive use of surveys (questionnaires and interviews), that centralized educational reform had serious consequences for instructional…

Appropriate for college geography students and researchers, this paper briefly introduces basic federal statistical publications and corresponding finding aids. General references include "Statistical Abstract of the United States," and three complementary publications: "County and City Data Book,""State and Metropolitan Area Data Book," and…

Traditional elementary statistics instruction for non-majors has focused on computation. Rarely have students had an opportunity to interact with real data sets or to use questioning to drive data analysis, common activities among professional statisticians. Inclusion of data gathering and analysis into whole class and small group activities…

This paper provides an analysis of a teacher development experiment (cf. Simon, 2000) designed to support teachers' understandings of statistical data analysis. The experiment was conducted as part of collaborative efforts between the author and a cohort of middle-school mathematics teachers during the 2000-2001 academic year. Analysis of the…

Reported are the impacts of a series of workshops for instructional improvement conducted by the Faculty Development Organization of Wittenberg University, a private, undergraduate institution of 2300 students. The impacts delineated are the results of an evaluation of these workshops. The impacts examined were extracted from the expected outcomes…

School-related time allocations of students, including time at home, as reported in sample surveys of students, teachers, and parents, are examined for systematic relations to socioeconomic indicators, controlling for ability. Special attention is paid to teacher-influenced student time allocations such as instructional time and homework. The aim…

The California School for the Deaf (CSD) conducted a study to familiarize students and faculty with available programs at Lawrence Hall of Science and to see if the instruction and teaching philosophy used to introduce the programs was adequate for students with impaired hearing. The pilot study was positive, so objectives were formed to adapt…
