This qualitative, instrumental case study examined how a mentor inquiry community can serve as a space for mentors to articulate their knowledge and what about the inquiry community, its characteristics, might harm or help that development. Using Design-Based Research as the methodology, a mentor inquiry community, composed of three…

These problems and activities have been used to demonstrate the uses of multiple representations as well as provide opportunities for students to practice using multiple representations in solving problems. (Contains 3 figures and 2 tables.)

External representations (ERs), such as diagrams, animations, and dynamic models are vital tools for communicating and constructing knowledge in biochemistry. To build a meaningful understanding of structure, function, and process, it is essential that students become visually literate by mastering key cognitive skills that are essential for…

Including gesture in instruction facilitates learning. Why? One possibility is that gesture points out objects in the immediate context and thus helps ground the words learners hear in the world they see. Previous work on gesture's role in instruction has used gestures that either point to or trace paths on objects, thus providing support for this…

Before the advent of symbolism, i.e. before the end of the 16th Century, algebraic calculations were made using natural language. Through a kind of metaphorical process, a few terms from everyday life (e.g. thing, root) acquired a technical mathematical status and constituted the specialized language of algebra. The introduction of letters and…

The possible use of a calendar algorithm was assessed in DBC, an autistic "savant" of normal measured intelligence. Testing of all the dates in a year revealed a random distribution of errors. Re-testing DBC on the same dates one year later shows that his errors were not stable across time. Finally, DBC was able to answer "reversed" questions that…

Used descriptive analysis and a forced choice task to investigate childrens' and adults' production, interpretation, and judgment of notation. Results showed that young children may not impose the same symbol-meaning structure at decoding that was proposed at encoding. Only after this ability develops does a preference for one form-one function…

Discusses development of symbolic thinking in toddlers as a step in language acquisition and skill development. Examines means of encouraging this symbolic problem solving, such as setting the stage for problems, helping children plan problem-solving strategies, and encouraging children in self-evaluating their skills. Examines development of…

Technology, software, and design activities that have been used to create presentations for a class in visual literacy taught to graduate students in the instructional technology program of Northern Illinois University are described. In the past, the language of visuals was introduced through a slide and tape produced for the class. An additional…

This research analyzes language development in the classroom as fostering the development of students who are community builders, problem solvers and critical thinkers. Examples of both positive and negative classroom situations are used to illustrate these three language domains. Successful classrooms are safe communities where children are…

THIS BOOK ABOUT THE FUNCTIONS OF LANGUAGE IN HUMAN LIFE EMPHASIZES LEARNING HOW TO CLASSIFY, DEFINE, AND ANALYZE. FOLLOWING AN EXPLANATION OF THE PHYSIOLOGICAL AND PSYCHOLOGICAL ROOTS OF LANGUAGE, CHAPTERS ON ANALYSIS, MEANING, SIGNS, AMBIGUITY, SEMANTIC GROWTH, AND METAPHOR LEAD TO A DESCRIPTION OF THE COMMUNICATIVE FUNCTION OF LANGUAGE,…

Efforts to contain the spread of Acquired Immune Deficiency Syndrome (AIDS) have been slowed by numerous arguing factions, political, religious, and medical, all of which perceive the AIDS epidemic through a different set of symbols. The images can be more easily understood using Kenneth Boulding's Threat, Integry, and Exchange (or TIE) model. The…

This longitudinal study investigated the ways in which two groups of eight students used spreadsheets to represent and solve algebra problems and related this to their previous arithmetical experiences and evolving use of symbolic language. The spreadsheet environment supported students to move from specific to general thinking. Includes story…
