Research detailes
• The aim of our study: test OP4L learning environment and its services, assess students‘ relationship with collaborative learning
• evaluation:• before testing OP4L learning environment
• after testing OP4L learning environment

Participants
• Computer Science students -1st year (Faculty of Electrical Engineering and Computer Science),
• volunteers signed consent form,
• 62 participants • all male,
• age in years (Mdn = 20, Mean = 20.73, Min = 19, Max = 25),
• experience in programming.
Company LOGO
Participants
• experience in programming (5 levels)

Procedure
• Three weeks in May 2012
• Two classroom meetings:• 1st meeting: before testing, instructions were given,
questionnaires were filled in,
• 2nd meeting: after testing, questionnaires were filled in,
• The task:• brainstorming,
• submission of proposed idea,
• programming,
• submission of the program,
• assessment of the program.

Measures
• Quantitative research metod (questionnaires),
• Evaluation before testing OP4L:• A questionnaire on the habits of using Facebook,
Facebook chat and Web resources,
• Evaluation after testing OP4L:• A questionnaire on the habits of using Facebook,
Facebook chat and Web resources (the same as before testing),
• A questionnaire on the experience in OP4L learning environment,
• A questionnaire on collaborative learning and using Facebook in favor of collaborative learning,
• A questionnaire on the usability of OP4L learning environment (SUS),
• Motivated strategies on learning questionnaire (MSLQ).
Company LOGO
Measures
• Likert-type questions and open-ended questions
• questionnaires were put online.

Statistical analysis
• Descriptive statistics,
• definition of statistically significant relationships (Spearman‘s Rho coefficient),
• Kruskal-Wallis Test (differences among independent samples),
• SPSS 20.0.

Results Experience in OP4L learning environment
• Assessment of OP4L services:• Recommended peers (idea vs. usage)
• Recommended readings (idea vs. usage)
• idea – from pedagogical and functional point of view
• usage – from pedagogical and functional point of view, technical operation

Results Opinions on usability of OP4L learning environment
• Bad responsiveness of the system.
• Too many clicks were needed to be able to come to the task.
• Problems with submitting and assessing the tasks.
• Communication with others was too complicated.
