Brief statement of principle
Instruction leads to more robust learning when it guides the learner's attention ("focuses") toward relevant features of the material, as opposed to unfocused instruction or instruction that guides attention toward irrelevant features.
Description of principle
This principle involves encouraging students to focus on the key knowledge components in the educational material they are studying. Feature focusing instruction may help students to learn knowledge components with higher feature validity. More geneally, attention focusing may also result in students spending more time during a learning event on a particular knowledge component and thus increase its strength.
Operational definition
Instruction that guides the student to key knowledge components will result in superior long-term retention than unfocused instruction.
Examples
Examples include:
the Note-Taking studies in the Refinement and Fluency cluster.
basic skills in Chinese
learning French gender cues
learning Spanish conjugation
Experimental support
Laboratory experiment support
Two note-taking studies have found that when copy-pasting notes, students perform better on both Normal post-tests and long-term retention tests when they make selections that include only single ideas, rather than multiple ideas. While behavioral interventions have been effective in reducing selection size, they have not produced increased learning outcomes. With regards to note-taking students' ability to identify key knowledge components may be limited by their understanding of the material, rather than the note-taking interface.
In vivo experiment support
See the following PSLC studies:
- FrenchCulture
- Learning the role of radicals in reading Chinese
- Chinese pinyin dictation
- Learning a tonal language: Chinese
(The authors of these studies should add a sentence or two summary of their findings in this section as well as update other relevant sections on this page.)
Theoretical rationale
Feature focusing is a refinement process, where students are identifying the key ideas, and rejecting irrelevant or unimportant ideas. With regards to feature focusing in learning of explicit textual content, focusing on key ideas may be related to previous results where summaries were found to produce superior outcomes to full text (see Reder & Anderson).
