This study examines the computer-mediated discussion topics of parents who raise bilingual and multilingual children in four active Facebook and Internet forums, and investigates how the language ideologies embedded in the multiple languages being used in these forums are expressed. In this study, 179 data points, including users’ posts and thread comments, were collected to identify the most frequently discussed topics as part of my description of the database, in order to identify parental ideologies by using values analysis. The five most-discussed topics were selected to make a critical discourse analysis on the narratives to understand the language ideologies regarding the use of multiple languages, and regarding what users of the groups are saying specifically about the languages when analyzing metalinguistic discourses. This study found the most recurrent language ideologies that parents expressed on these online forums were supporting bilingualism/multilingualism, and claim that bilingualism/multilingualism is advantageous. Parents also demonstrate language ideologies supporting keeping languages separate, such as following the one parent one language (OPOL) method, using the minority language at home, and so on. A detailed values analysis with illustrative sample messages from the online posts and comments also more specifically shows the recurrent language ideologies identified, and parents’ views underlying their narratives on their posts and thread comments.
