Shares examples of reports of uncertainties that exceed the guideline of one or two significant figures. Points out that scientists should take great care in deciding on the appropriate form for reporting their results. (DDR)

Discusses the foundations of recordkeeping learned in a group analysis of achievement test data for a Montessori school, including having a student database and numbering system, and recording achievement test results. Describes ways to analyze achievement test results, chart results, use charts to identify trends across school years, and conduct…

"How the World Works" is an interdisciplinary science and mathematics course in which students design and perform their own experiments, analyze the data, and present their results orally and in writing. Evaluations indicate that most students learn how to do science and gain a better appreciation for science as a process. (SAH)

Guidelines are offered that make it more likely that high-quality information will be extracted and coded from primary research reports in meta-analyses. It is also noted that the methodology of meta-analysis results in pressure to change the type of information that appears in primary research reports. (SLD)

Responds to Rubin and Knox's (1996) article concerning data analysis in single-case evaluations. Refutes the assertion that ambiguous data patterns discourage clinicians from doing single-case evaluations, and questions the assertion that emphasis on single-case designs should be reduced in the social work curriculum. (JPS)

Provides the second half of an extensive study examining research in developmental education, evaluating the quality of the research based on a sample of 52 randomly selected articles and conference presentations. Discusses problems encountered in the studies related to the design implementation, and analysis of results from research. (33…

Analysis of data on family support services and spending for individuals with developmental disabilities presents information on cash subsidy payments, respite care, and other family support. A graph shows U.S. spending for family support, 1986-1998. Additional tables break down subsidy spending for family support services by state in 1998 and…

Examined analytic methods for describing children's social risk. Found that the individual-risk-variables approach provided better overall prediction of developmental outcomes at a particular age. The risk-factor approach provided good prediction of developmental trajectories with moderate to large sample sizes. The risk-index was useful for…

Suggests ways to use dynamic systems analysis to illuminate the pluralistic and multidimensional model described by Larivee, Normandeau, and Parent (2000). Issues discussed include the characteristics of developmental transitions, such as hysteresis; nature of growth processes, such as hierarchical development or predator-prey interactions; and…

Considers individual students' progress as they use tools, discuss data distributions, and interact with teachers and their peers. Suggests that data display tools provide a partial context for discussions but do not constrain the students' interpretations or the way they reason about the data. (Author/MM)

Shares three ideas concerning how to evaluate the practical importance of developmental findings to make them more useful to policymakers: (1) statistical significance tests need to be accompanied by effect size estimates; (2) meta-analyses are helping in using all existing data when examining issues involved in policy debates; and (3) researchers…

Presents some examples illustrating the importance of probability, data analysis, and statistics for the preservice mathematics teacher, and suggests ways of teaching these topics. (Contains 13 references.) (ASK)

Teachers' quests for more data-based planning, problem solving, and decision making often stumble against limited capacities for engaging in thoughtful interactions, with groups typically lacking process tools, collaborative communication skills, and reflective habits. This article presents a three-phase model for guiding data-driven dialogue in…

Research strategies related to data collection and data analysis were identified through content analysis of 427 articles in three comparative-education journals, published between 1985 and 1995, and 112 articles published between 1964 and 1966. In recent years, the strategies used have become more diverse, the geographic focus of research has…

Describes the benefits of an activity in which students analyze a data set comprised of information from obituaries found in local newspapers. The activity combines two instructional approaches: (1) hands-on learning; and (2) generalizing underlying principles to new situations. Discusses the outcomes of student learning from the activity.
