This paper describes the process for employing two principal instruments for relating the categories identifying the central phenomenon in grounded theory analysis. The Conditional Relationship Guide contextualizes the central phenomenon and relates structure with process. The second tool, the Reflective Coding Matrix, captures the higher level of…

While preparing to migrate from Innovative Interfaces' text-based serials module to its new Millennium Serials product, the author, a manager of technical services operations in a small academic library, found herself faced with a number of decisions regarding how to store holdings information. Holdings data is information about individual items…

The 10th International Conference on Educational Data Mining (EDM 2017) is held under the auspices of the International Educational Data Mining Society at the Optics Velley Kingdom Plaza Hotel, Wuhan, Hubei Province, in China. This years conference features two invited talks by: Dr. Jie Tang, Associate Professor with the Department of Computer…

This article describes the construction of a hierarchical taxonomy of metacognitive activities for the interpretation of thinking-aloud protocols of students in secondary education, who studied texts on history and physics. After testing an initial elaborate taxonomy on a restricted number of protocols by multiple raters, it appeared that the…

The authors present 10 experiments that challenge some central assumptions of the dominant theories of visual search. Their results reveal that the complexity (or redundancy) of nontarget items is a crucial but overlooked determinant of search efficiency. The authors offer a new theoretical outline that emphasizes the importance of nontarget…

Mathematical signs and symbols have a decisive role for coding, constructing and communicating mathematical knowledge. Nevertheless these mathematical signs do not already contain mathematical meaning and conceptual ideas themselves. The contribution will present basic elements of an epistemology of mathematical knowledge and then apply these…

This study was conducted in response to several recent incidents in which teachers and student teachers were reprimanded for content they placed on the Internet. This study examined the Facebook postings of preservice elementary teachers to determine the extent to which these postings are congruent with expected dispositions. Profiles were…

In this paper, we report on a series of algebra classes with a group of low-income, African American mothers of elementary-aged children who had limited and negative formal experiences with algebra. We drew from United States reform-oriented elementary mathematics curricular materials in the classes. The women initially arrived to the class out of…

Parent-child "everyday" conversations have been suggested as a source of children's early science learning. If such conversations are important, then it would be pertinent to know whether children from different family backgrounds have different experiences talking about science in informal settings. We focus on the relation between…

Facing the ambiguous status of in-school music literacy, this follow-up eight-year study aims to touch on the effects of traditional staff notation (SN) learning on student's intuitive symbolizing behavior and musical perception. Subjects were 47 second-graders attending a religious Jewish school in Israel. One "pre-literate" meeting, in…

This manual was written as part of a study entitled "Studying the Cost and Value of Library Services," conducted from fall 1993 through spring 1995. The goal of the study was to address the problem of developing models and methods for studying the cost and value of library and information services in a way that can be pragmatically…

A previously developed method of automatically selecting items for inclusion in a test subject to constraints on item content and statistical properties is applied to real data. Two tests are first assembled by experts in test construction who normally assemble such tests on a routine basis. Using the same pool of items and constraints articulated…

The Adult Education components of the 1991 and 1995 National Household Education Survey (NHES) collected the name and subject matter of a wide range of courses adults had taken in the previous months. Adult education involves a variety of types of courses, whether related to basic skills, equivalency programs, degree programs, or personal…

The National Household Education Survey (NHES) is a data collection system of the National Center for Education Statistics that is designed to provide information about educational issues best addressed through contacting households rather than institutions. In 1995, as in 1991, one of the components of this telephone survey was a study of adult…

This study is a critical evaluation of the roles for coding and scoring of missing responses to multiple-choice items in educational tests. The focus is on tests in which the test-takers have little or no motivation; in such tests omitting and not reaching (as classified by the currently adopted operational rules) is quite frequent. Data from the…
