As the global economy grows, the labor market's demand for qualified employees increases. However, the present situation is not able to meet labor market requirements; laborers are inexperienced, and their professional skills are inadequate. Collaboration between vocational schools and businesses is essential for educational activities. This study aimed to investigate the degree of perception, the contents, the forms, and the variables that influenced collaboration activities in practical training between vocational schools and businesses. A quantitative study method was conducted on 570 respondents (195 teachers, 125 managers, and 250 graduated students) randomly recruited from four provinces/cities in Vietnam. The results show that participants perceived the importance of practical teaching coordination activities in vocational schools and businesses. In addition, some contents and forms were applied to collaboration teaching activities between vocational schools and businesses Future studies should consider similar experimental studies to develop appropriate practical training collaboration activities models based on perception levels and factors impacting activities.

A number of social networking platforms have emerged as a result of the development of information and communication technology which have become increasingly user-friendly and full with valuable features. The social networking site with most users is Facebook. Teenagers, particularly college students use Facebook most frequently to study, gain information, entertain themselves and connect with others through self-disclosing personal information on the Facebook profile page. This quantitative study aimed to analyze the attitude of pedagogical students regarding self-disclosure on Facebook as represented through cognition, emotion and behavior concerning academic achievement. The survey was completed by 535university student’s majority in pedagogy. There were 41 students who used it for less than three years between three to five years by 218 students and 276 students who use it more than five years. The questionnaire was self-reported by participants to assess university students' attitudes toward self-disclosure on Facebook. The results indicate that pedagogical students with excellent academic achievement and more than five years of Facebook experience had the highest-level attitude toward self-disclosure on Facebook. The results indicate a positive relationship between cognition, emotion and influence factors students' Facebook attitudes. Future research on methods that enhance student positive disclosure can benefit from this study. Future research should examine how self-disclosure on Facebook relates to other aspects, such as Facebook usage time, financial state and perception of advantages and its disadvantages of Facebook in order to evaluate students' attitudes objectively.
