1. By Focus:
* Conversation Analysis (CA): Studies naturally occurring conversations, focusing on the structure, turn-taking, and interactional features of talk.
* Critical Discourse Analysis (CDA): Examines how discourse reflects, constructs, and reinforces social power relations, often with a focus on ideology, inequality, and social change.
* Corpus Linguistics: Analyzes large collections of text or speech data (corpora) to identify patterns and trends in language use.
* Pragmatics: Focuses on the meaning of utterances in context, including how speakers use language to achieve specific communicative goals.
* Sociolinguistics: Studies the relationship between language and society, including variation in language use across different social groups.
* Ethnography of Communication: Examines language use within specific cultural contexts, often with a focus on the cultural significance of language.
2. By Methodology:
* Qualitative Discourse Analysis: Uses methods like thematic analysis, content analysis, and narrative analysis to interpret the meaning of discourse.
* Quantitative Discourse Analysis: Employs statistical methods to analyze large datasets of text or speech, identifying patterns and trends.
* Mixed Methods Discourse Analysis: Combines qualitative and quantitative approaches to gain a comprehensive understanding of discourse.
3. By Application:
* Discourse Analysis in Education: Studies classroom interactions, student writing, and other forms of discourse in educational settings.
* Discourse Analysis in Health Communication: Examines how language is used in healthcare settings, including patient-provider interactions, health education materials, and medical research.
* Discourse Analysis in Media Studies: Analyzes how media texts construct meaning, shape public opinion, and influence social behavior.
* Discourse Analysis in Politics: Investigates the use of language in political campaigns, policy debates, and media coverage of political events.
It's important to note that these categories are not mutually exclusive. There is often overlap between different branches of discourse analysis, and researchers may use multiple approaches to study discourse.
Ultimately, the specific focus and methodology used in a discourse analysis project will depend on the research question and the goals of the study.
