This study explored the communication strategies of college students majoring in one of five modern foreign languages (i.e., English, French, German, Japanese, and Spanish) and their relation to communication confidence. It also explored the association between their strategy use and the difficulty regarding the speaking components, and students' feedback on pedagogical tasks to improve their speaking ability. A questionnaire survey of communication strategy was distributed to 538 college students in Taiwan, and semi-structured interviews were conducted with 20 students. The results showed that there was a statistically significant difference between the majored language and the use of communication strategies. Specifically, a one-way between-groups MANOVA revealed that the participants adopted the message reduction/alteration and fluency-oriented strategies frequently and equally, regardless of the language they studied. English and Spanish learners employed social affective, phonological awareness, and negotiation for meaning while speaking strategies more frequently than German learners. Students who reported difficulties in fluency, lexical resources, grammatical accuracy, and pronunciation while speaking the major language employed social affective strategies less frequently. Finally, students' preferences for particular tasks reflected the speaking components they wished to foster. It is concluded that lexical and grammatical knowledge should be emphasized first to build communication confidence and strengthen fluency. Plain language summary: Exploring How Students Learn Foreign Languages: Communication Approaches, Challenges, and Speaking Exercises This research looked into how college students who are studying different foreign languages (like English, French, German, Japanese, and Spanish) communicate and how confident they feel about it. It also checked if the strategies they use relate to how difficult they find speaking, and what they think about tasks meant to improve their speaking skills. I gave a survey about communication strategies to 538 college students in Taiwan, and interviewed 20 of them in more depth. The finding was that the language students were studying made a difference in the strategies they used. For example, students tended to use certain strategies, like simplifying their message or focusing on fluency, no matter which language they were learning. However, those learning English and Spanish used strategies related to social interaction, pronunciation, and understanding the meaning of what's being said more often compared to those learning German. Students who struggled with fluency, vocabulary, grammar, and pronunciation tended to use social interaction strategies less often. Also, the tasks students preferred for improving their speaking skills matched up with the aspects of speaking they wanted to get better at. In conclusion, it seems like building up vocabulary and grammar knowledge first can help students feel more confident in their communication and improve how fluently they speak. [ABSTRACT FROM AUTHOR]
