Integrated group discussion (IGD) tasks represent a new type of integrated speaking task that requires students to communicate with their peers after comprehending and using provided source materials. With its potential to enhance effective communication and information literacy, IGD stands at the core of language education. Although the IGD task type has become increasingly popular, its construct is still unexplored. In this study, 124 Hong Kong undergraduate students completed an IGD task and a group discussion (GD) task (i.e., without source materials) in Putonghua. Four factors, speech and expression, content with source use, interaction, and language usage, were extracted to represent IGD performance. Two indicators of GD performance (linguistic expression and engagement in interaction) significantly predicted IGD performance, explaining 21.9 % of its total variance. The large proportion of unexplained IGD performance variance suggests that IGD tasks may be worth implementing. The theoretical and practical implications of the findings are discussed in details. Copyright © 2024 Walter de Gruyter GmbH, Berlin/Boston.

Given the increasing awareness of oral communication in this era of globalized collaborative learning trends, there is an imminent need to inform language educators of ways in which the under-researched oral interactional strategies are related to first language (L1) teaching. However, no consensus has yet been reached on the relationship between interactional strategy use and oral language proficiency. This study investigates the effect of oral interactional strategy use on group discussion performance in L1 Chinese for Primary 5 students (N = 140) in Hong Kong. Based on ANOVA and regression analyses of the data on group discussion performance, five strategies have been identified: expressing actively, asking for opinion, expressing attitude, giving clarification and non-verbal language. They all significantly predicted students’ group discussion performance, with overall strategies explaining 55.5% of total variation of the performance, where higher-proficiency students tended to use more strategies that enable comprehension and elaboration in the group discussions. The patterns of strategy use among students with different levels of discussion performance have also been identified. Implications of the findings are discussed with reference to the roles individuals play in the overall performance of group discussion. Copyright © 2019 Walter de Gruyter GmbH, Berlin/Boston.
