This paper introduces the LEGO® Database, a large natural dataset that can be used to teach Structured Query Language (SQL) and relational database concepts. This dataset is well-suited for introductory and advanced database assignments and end-of-semester group projects. The data is freely available from Kaggle.com and contains eight tables with…

We describe a method for analyzing student data from online programming exercises. Our approach uses contingency tables that combine whether or not a student answered an online exercise correctly with the number of attempts that the student made on that exercise. We use this method to explore the relationship between student performance on online…

The purpose of this content analysis was to examine in detail the nature and extent of messages about sex that are presented in the "family hour" on broadcast network television. The research sought to identify any patterns that exist in portrayals of sexual behavior as well as characters' talk about sex, using a sample of programming…

Describes a study that examined 48 television stations seeking FCC (Federal Communications Commission) license renewal in 1992 and assesses their efforts to fulfill the programming requirements of the Children's Television Act (CTA) of 1990. Educational programming requirements are explained, and results are reported that indicate inadequate…

Examines family relationships in domestic comedy; participants evaluated samples of 13 programs from a selection of popular shows during the period from 1950 to 1990. Spousal and parent-child relations were evaluated. The study yielded no support for the claim that family relations have deteriorated in the television family. Three tables present…

This report analyzes data gathered from 29 automated library system vendors who responded to a 1996 survey. The survey also requested their perceptions of Java (an object-oriented programming language) and network computers, and issues and trends to be considered by library administrators. Contact information about the vendors is provided. (Four…

Presents the results of a survey of 18 vendors of PC- and Mac-based multifunction library systems that include either circulation or patron access catalogs. Highlights include software alone or turnkey systems, operating systems, programming language, sales, profitability, and support staff. (LRW)

Creating educational software generally requires a great deal of computer expertise, and as a result, educators lacking such knowledge have largely been excluded from the design process. Recently, researchers have been designing tools for automating some aspects of building instructional applications. These tools typically aim for generality,…

As part of the annual Yankelovich Monitor survey, extensive demographic, attitudinal, and product usage data were gathered about people who donate money to public broadcasting. Of the total population polled, 11% said they had donated to public television, and 4% said they had donated to public radio in the past two years. This report explores the…

Discussion of the use of programming as a learning activity focuses on software-realized scaffolding. Emile, software that facilitates programming for modeling and simulation in physics, is described, and results of an evaluation of the use of Emile with high school students are reported. (Contains 95 references.) (LRW)

Since 1996, the Annenberg Public Policy Center (APPC) has tracked and reported the availability and the quality of programming specifically designed for children. This report evaluates the availability and quality of children's programming in the 1998-99 season and examines factors that may have influenced the quality and quantity of programming.…

Discussion of the time needed to create computer-based instruction focuses on descriptive analyses of production data gathered from novice instructional designers and novice authors who used a commercial authoring system to produce computer-based lessons. Production ratios are explained, and future research plans are discussed. (Contains five…

Describes a study that analyzed television series programs from 1950-89 featuring families to identify racial/ethnic composition, number of children, head of household, marital status, and family configuration and to compare television family characteristics with real families based on census figures. (16 references) (LRW)

Describes a study of 647 preservice teachers in Ontario that used the Computer Ability Survey (CAS) to assess 4 components of computer literacy: software ability, awareness, programming skill, and perceived control. Correlations and validity for the CAS are discussed, and results of a principal-components factor analysis are reported. (Contains 39…

Examines research on computer-based mathematics learning in the context of constructivist learning and the National Council of Teachers of Mathematics Standards. The reviewed studies examined the effectiveness of computer software in the three categories of programming, computer-assisted instruction, and mathematical tools. Future research is…
