He is involved in designing, developing and evaluation of computer-supported learning environments. Miikka Miettinen, Patrik Floréen and Henry Tirri are members Abstract A shared document-based annotation tool was presented, and its usefulness in two different real-life web-based university-level courses (adult learners, n = 27 and adolescent learners, n = 23) was empirically investigated. The study design embodied three data collection phases: (1) a pretest measuring selfrated motivation, learning strategies, and social ability; (2) log file data analysis showing actual use of the system features; and (3) a posttest in a form of an email survey. For both groups, the results showed that the level of motivation has a positive effect on activity in the system and the final grade. The learners, who reported to have good time-management strategies, were the most active users of the system. The level of social ability predicted both the number of consecutive comments in the documents and the threads in document-related newsgroup discussions. Log file data analysis showed that user activity in the system was positively related to the final grade in both samples. Results of the posttest showed that all the respondents agreed when asked: (1) if the system brought added value to the learning process; (2) if the use of the system changed their studying habits favourably; and (3) if they would like to use the system in other courses.

as the attendance scales without an upper bound. Schools in Finland have offered the MOOC as an elective CS course for their students and granted formal school credits for completing (parts of) it. Since our MOOC is exactly the same programming course as our university-level CS1 course, we are able to use the MOOC also as a long-lasting entrance exam to the CS BSc and MSc degrees. After two spring semesters of operation, we have observed that there are school students dispersed around Finland who are ready and willing to take on a challenging programming course online, and bridging the MOOC to a full study right makes a strong incentive to keep working on the programming assignments, even without traditional teaching.
