This study focuses on the influences of self-efficacy beliefs in English learning between male and female university students. There was a total sample of 128 university Non-English majors from Dong Nai Technology University in Bien Hoa city. The quantitative component used a questionnaire asking about students’ background and their self-efficacy beliefs in learning English. Ten students were individually interviewed to be able to clarify the reasons that affected their self-efficacy beliefs and their English performance. T-test was used to find out the gender differences in self-efficacy level and English achievement degree. The result showed that there was a positive relationship between self-efficacy and achievement. Differences between male and female students in their confidence levels and English learning performance were found. The thesis finishes with a set of recommendations for teachers to pay attention to the importance of self-efficacy because it influences learning English achievement.

Social media tools are a new type of media with a variety of properties and characteristics. Today, the use of social media is increasing at an alarming rate. Students can digitally meet up with their peers and teachers in this realm. They are able to discuss important topics that are connected to their learning process. This study aimed to see how social media tools in Moodle affected English writing skills in narrative paragraphs and whether social media tools in Moodle may help enhance English writing skills in the narrative paragraph. The current study used a mixed-method strategy that included quantitative and qualitative methodologies such as interviews and questionnaires, as well as an experimental research method. To investigate the impact of using social media platforms on boosting students’ writing, pre-and post-tests were used to assess students’ performance before and after the experiment. The three instruments, the questionnaire, the interview, and the quasi-experiment (pre-post-test), revealed how Moodle’s social media facilities affect students’ English writing skills. Using social media features in Moodle helped students improve their writing skills and enhanced their motivation when creating recount narratives. As a result of this research, it is recommended that social media be integrated into Dong Nai Technology University to increase the students’ other skills dramatically.
