Study reported in this paper analyzed over twenty thousand machine-readable library metadata records in MARC 21 bibliographic format that are based on Resource Description and Access (RDA) standard. The focus of this analysis is on change in subject metadata-data elements designed for representing the aboutness of information objectsover a 6-year period between 2014 and 2020. The analyzed dataset is the entire population of the records representing English-language video recordings in DVD format in WorldCat database as of one year after official transition to RDA data content standard in library metadata creation. Analysis of metadata representing audiovisual materials is needed as audiovisual metadata practices tend to differ from those for other materials due to high occurrence of unique resources. The study includes quantitative and qualitative analyses into the change in the application of data elements (fields and subfields) over time and categorizes the observed change.
Objective: This research study examined textbook costs and student success rates at one community college in the Southwest United States. Method: Descriptive statistics were used in the study to identify the mean textbook costs and student success rates over five semesters. Chi-square tests for independence were used to determine if a statistically significant relationship exists between textbook costs and student success rates based on course level of lower or upper-level courses. Results: The chi-square tests of independence found a statistically significant relationship between textbook costs and student success rates in lower and upper-level courses. Contributions: Research shows college students often opt not to purchase commercial textbooks due to costs, thus resulting in higher D, F, and W rates. The results of this study support numerous recent research studies on the impact of textbook costs and student success.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
