Common goals of OOP coursesFocus on fundamental OO software development
tasks and programming concepts rather than simply learning Java constructs
Comprehending and using standard library-classes, analyzing/extending existing user-defined classes
Becoming familiar with the language syntax and semantics, implementing programs, designing simple OO applications

Assessment procedures and toolsUOM-TMD UNS-PMF MUNI-FI
LMS’s tool for assignment, submission and management of programming projects.
Correction of assignments, midterm and final exams is done manually.
LMS Moodle as a tool for testing students’ theoretical knowledge (using Quiz module) and small tests for self-evaluation.
In-house Svetovid system for assessing students programs.
Moodle for administration of all points and final grades.
LMS’s tool for assignment and submission (“vaults”).
Correction of midterm and final exams is done manually.
Correction of tasks may be in some groups done semi-automatically.

Communication and cooperationUOM-TMD UNS-PMF MUNI-FI
Announcement tool with integrated e-mail system & discussion forum of the LMS
However, and despite the strong encouragement to use LMS for communication, students prefer to contact the instructor in person or through email.
The forum is used rarely and by very few students.
E-mails and LMS Moodle: discussion forums, instant messages, chat sessions, e-mail.
Wikis as obligatory part of team-work projects in several courses.
Students still are not very eager to use e-learning 2.0 communication capabilities.
Announcement tool with integrated e-mail system & discussion forum of the LMS
The social networking functionality that is experimentally used in selected advanced courses has not been introduced here (yet).
Students prefer to contact the teacher directly

Conclusions from non-parametric statistical tests
High similarity between PMF-UNS and MUNI-FI regarding the perceived importance of TEL services
Students from UOM-TMD tend to give higher ratings to those items for which statistically significant differences among countries are observed
Perceived importance of TEL services is mostly not affected by year of study
UOM-TMD students with the lowest average grade consider TEL services less important compared to others
Perceived importance of TEL services is not affected by average grade at PMF-UNS and MUNI-FI
