The Center for Advanced Language Proficiency Education and Research (CALPER) at Pennsylvania State University (PSU) has a number of wonderful resources on the web. Check out this link to its publications page, which focuses highlights publications that use culturally based, spoken interaction as a tool for teaching language. Publications here include those for Korean, Chinese, Japanese, and Russian acquisition, but they also have publications that discuss processes more generally, including acquisition activities that might be done on computers.
Teachers in k-12 might not think that this page is for you, but it’s still worth a look. Although you may not be teaching your students Korean, you may find that the same techniques that facilitate second language acquisition (SLA) also work to heighten your students awareness of English language patterns. Especially if you have students who are learning English as a Second Language (ESL), these publications may help you to better understand the processes those students are going through.
