The document discusses cognitive and metacognitive strategies used in learning a second language. It lists cognitive strategies such as repetition, translation, note-taking, deduction, and inferencing that are applied when a learner encounters new information. Metacognitive strategies involve directing attention, selective attention, self-monitoring, self-evaluation, and self-reinforcement to plan, implement, monitor, and evaluate language learning performance. Metacognitive knowledge refers to declarative knowledge about cognition used to select strategies for different learning situations.
