The purpose of this study was to assess structural knowledge change across a two-week workshop designed to provide high-school teachers with training in Java and Object Oriented Programming. Both before and after the workshop, teachers assigned relatedness ratings to pairs of key concepts regarding Java and Object Oriented Programming. Their…

A considerable amount of experiences in teaching object-oriented concepts using the Java language have been reported to date, some of which describe language pitfalls and concrete learning difficulties. In this paper, a number of additional issues that have been experienced as difficult for students to master, along with approaches intended to…

Constructing a data model for a problem area requires identifying and formulating some symbolic representation of the concepts involved, their characteristics, and the relationships between them. Taking a socio-cultural perspective on learning, analysis of classroom dialog is used to identify cognitive challenges met by novice students of data…

Instructors teaching beginning programming classes are often interested in exercises that involve processing photographs (i.e., files stored as .jpeg). They may wish to offer activities such as color inversion, the color manipulation effects archived with pixel thresholding, or steganography, all of which Stevenson et al. [4] assert are sought by…

From 1942 to 1958, a national weekly programme on CBS radio and presented by Science Service, Inc. devoted 37 of its broadcasts to profiling American high school students' achievements in science talent searches, clubs and fairs. These "Adventures in Science" radio programmes cast scientifically talented youth as potential contributors to national…

We report on responses to a series of four questions designed to identify pre-existing abilities related to debugging and troubleshooting experiences of novice students before they begin programming instruction. The focus of these questions include general troubleshooting, bug location, exploring unfamiliar environments, and describing students'…

The Machine Tool Program at Cowley College in Arkansas City, Kansas, is preparing students to become future leaders in the machining field, and the school recognizes the importance of sharing and celebrating those stories of success with the public to demonstrate the effectiveness of career and technical education (CTE) programs. Cowley College is…

The Federal Communications Commission (FCC) has been progressing over the past 5 years toward the institution of Direct Broadcast Satellite Radio (DBS-R) which would institute a new type of radio service. The FCC refers to the service as Satellite DARS (Digital Audio Radio Service), and it would provide reliable, high-fidelity satellite-delivered…

This paper discusses the use of ontologies and their applications to assessment. An ontology provides a shared and common understanding of a domain that can be communicated among people and computational systems. The ontology captures one or more experts' conceptual representation of a domain expressed in terms of concepts and the relationships…

This paper is an initial examination of prime time television's response to the events of September 11, 2001. Based on a review of the 2001-2002 television season's prime time programs, the study identifies 15 programs (out of 65 that ran the entire season) that incorporated September 11th elements. Themes of these programs are discussed as are…

Schools in two New York State counties are creating Web home pages with little money or technical expertise. Approaches to Web page construction include using commercially developed software (like Pagemaker or Claris Works); trying out downloaded shareware programs; using an online service (America Online, Prodigy, or Compuserve); and programming…

Developed a method based on 0-1 linear programming to stratify an item pool optimally for use in alpha-stratified adaptive testing. Applied the method to a previous item pool from the computerized adaptive test of the Graduate Record Examinations. Results show the new method performs well in practical situations. (SLD)

Presents a method for augmenting a Standard Generalized Markup Language (SGML) document repository with database functionality. Introduces an implementation method for a complex-object modeling technique, and describes interface techniques tailored for text databases and concepts for a Structured Document Database Management System (SDDBMS)…

Discusses how to translate your data from Standard Generalized Markup Language (SGML) to other formats. Explores key features and concepts of tools that address this problem and relates the problem to the Document Style Semantics and Specification Language (DSSSL) standard. Also investigates translation problems and the roles of SGML and DSSSL in…

Briefly describes four different electronic learning options available from the private sector: Off-the-shelf courseware, authoring tools and learning content management systems, virtual classrooms, and custom content. (PKP)
