Types of Changes That Occur as Declarative Knowledge Increases
Oosterhof, Albert
Online Submission
Declarative knowledge involves being able to state and explain characteristics, terminologies, properties, phenomena, concepts, principles, and techniques. Chi and Ohlsson (2005) characterize it as the dominant form of knowledge, maintaining that it does not involve isolated units but rather is organized as semantic networks, theories, schemas, or some combination of these. They propose seven types of changes--larger size, denser connectedness, increased consistency, finer grain of representation, greater complexity, higher level of abstraction, and shifted vantage point--that occur as declarative knowledge increases. The present paper provides a summary description of each type of change and offers illustrations relevant to science education. This content area is the focus of our present research, in which we examine an alternative approach to large-scale testing, much of which involves complex declarative tasks. When selecting or developing tasks, considering the types of changes described in Chi and Ohlsson's framework helps the validity of assessments. (Contains 1 table.)
