Cognitive Structuring: Task- based performance assisting LinKai Jiang Teachers College, Columbia University

Research Question What is the role of task in the process of cognitive structuring?

What is cognitive structuring? (Tharp & Gallimore 1988) Type 1: provides a framework to structure the content. Ex. “carrots are vegetables” Type II: provides a framework to structure the cognitive activities. Aka learning strategies

Data & Method 3.5 hours of video recording from two adult community English classes(CEP&CI). Classroom documents. Line by line analysis of verbal utterance. Classroom documents used to provide context & to support the argument.

Grammar-based Strategy Step 1: Identifying the word type. Step 2: transforming the new word into a different word type. Step 3: verifying the definition of the new word in the context of a sentence.

CI Student Task Without using a dictionary, the students worked in pairs to figure out the meaning of the underlined word or phrase in the sentences taken from a NPR story on diabetes. "The rates of diabetes are going up by almost an order of magnitude over the last generation, and they are going up very rapidly in the U.S. too."

Semantics-based Strategy Identifying the relevant semantic parts of the sentence and making the semantic relationship explicit.

Findings CEP Case: grammar-based strategy helps student score almost 100% on the test. CI Case: dwelling on the grammar would not help the students.

Limitation & Future Research Need longitudinal analysis of student work and a comparison of their understanding before and after being taught the learning strategy. Linking teacher action to student learning outcome.

Pedagogical Implication Learning strategies need to be repeatedly applied with a consideration of the specific nature of tasks in order to be effective.
