22. Grading: Project Group grade – 3% for each progress report (total 15%) – 10% for the final report – 10% for the final presentation Individual adjustment – For each report: 30% is related to individual contribution and involvement. Done your part of work: 15% Participation: 15% IST21022

23. Some Challenges You Will Face … Individual assignments – Some are time-consuming – Make good use of the office hours Programming – HTML, PHP, SQL – Do not worry about grading if zero experience 9% individual programming assignments Projects are done as a team No programming (HTML/PHP) in midterm exam and final Team project – This project is not something you can finish within 3 days, not even 3 weeks! – Team work is the key. IST21023

24. Team Work: Case Study Every semester, after finishing the project, I asked each team to write down what they have learnt… and here’s what one team say: StudentA (the “zero-experience” guy): I haven’t had very much coding experience. … However, working in this smaller group helped allow me to ask specific questions that I maybe didn’t know how to ask before. [StudentB] was extremely helpful with the SQL statements. [StudentC] helped clarify all of the PHP trouble that I was having in the beginning of the semester…. All in all it was a great experience and I’m really proud of the end result.

25. Team Work: Case Study StudentB (the “average” guy): …Working with [StudentA] and [StudentC] helped clarify some of the questions I had and really gave me the addition hands on experience that I needed in working with PHP…. To complete this project a lot of teamwork was needed. Each team member was able to use their strengths and help others with their weaknesses. StudentC (the “genius”): Obviously coming into this class with an extensive programming background and years of coding under my belt, much of the HTML and PHP was not at all a challenge to me. Early on I knew this would be the case and so I really pushed myself to do something really awesome, something that would actually be a rewarding challenge for myself, and hopefully my team as well…. I was extremely impressed with the results…including backend PHP and SQL done exclusively by the oh so awesome [StudentA] and [StudentB].
