This study investigated the accuracy of classroom teachers' judgments of the reading progress of their low-performing students. Participants were 36 second grade teachers and students in their lowest reading groups (n = 150). Student progress was monitored weekly using reading-curriculum-based measurement (R-CBM) procedures. After 6 weeks,…

Describes the learning experiences of young children meeting stem-and-leaf plots for the first time. Presents a vignette that offers a real and dynamic example of how young children can learn, use, and evaluate this powerful statistical display. (Author/ASK)

Reports the results of an informal study of very young children's reactions to some visual displays of data. (Author/ASK)

Pre- and posttests and interviews concerning misconceptions and alternate conceptions of rates of change were administered to (n=42) students in first-semester calculus using a conceptually-motivated curriculum. Suggests that an emphasis on visual representations through construction and interpretation in conjunction with teacher-student analysis…

Library user guides from seven large academic libraries were examined for readability using microcomputer software for analysis. Results indicated that most guides are written at or above a reading level of grade 12. Appendices summarize readability formulas and depict in a composite graph the levels of all of the guides examined. (16 references)…

Fourth graders (n=204) and seventh graders (n=185) were given a prior-knowledge inventory, a graph test, and reading and achievement tests during four testing sessions. Significant predictors for graph comprehension were identified for both grade four and grade seven students. The results suggest that children should be involved in graphing…

Examines the line graphing ability of middle/high school students (N=625) to provide baseline data on the mastery of line graphing subskills. Results show that seventh- and eighth-grade students were less successful in graphing than high school students, suggesting that graphing skills should be introduced and emphasized in earlier grades.

Describes research using a pedagogic strategy developed during an exploratory work called Active Graphing in which access to spreadsheets allows graphs to be used as analytic tools within practical experiments. Identifies aspects of student interaction with the experiment itself, the data collected and the graphs, and traces the emergence of…

Reasons for color in sedimentary rocks are explored. Graphs relating the color of rock and corresponding organic content and oxidation state of iron, and of the temporal evolution of a rock sample, are presented. The development of these graphs is discussed. (CW)

Reviews the Linked Systems project protocols in the Name Authority Distribution Application and describes the requirements they were designed to meet. A technical evaluation of the protocols in actual operation at OCLC is presented, and suggestions for improved performance are made. (Author/CLB)

In the winter term of 1979-1980, 692 faculty members and 1,319 students responded to a library use study conducted at the Technishe Universitat Wien (Vienna, Austria). Among other topics, the hours of operation of the main library were studied. Results show that more than 50% of the faculty and more than 70% of the students consider the…

This summary reports the highlights of a survey on microcomputer usage in institutions of higher education which was sponsored in part by EDUCOM. Software issues are emphasized, including assistance in evaluation, integrating software into the curriculum, and policy and procedures concerning illegal access and duplication. (LRW)

This paper describes student difficulties in first-year calculus classes and suggests some instructional strategies to address these difficulties. Participants in this study were 200 low socio-economic background freshmen majoring in business in Brazil. Results show that the main difficulties are related to lack of understanding of algebraic…

Determined is the logical reasoning necessary to construct line graphs including a straight line with a positive or negative slope and an exponentially increasing curve. The responses of subjects (grades 6-12) were classified into one of nine categories fitting with Piagetian operational structures. (Author/YP)

Based on a study of the book collection of Columbia-Greene Community College Library (New York) carried out in the summer of 1987, this report investigates the relationship of age and previous use to the future use of books. An examination of the acquisition year and circulation records of 10% of the library's book collection (approximately 4,000…
