• A 5* course book• slides provided
• not always a blessing for the lecturer!• Jdsl, the java data structures library• Took some months to make choice of book• Also got Bruce Eckel’s book TIJ

• Course work e-submitted and e-marked• students can mark in advance• no real problems• students accepted this.
• Plagiarism detection• 3 levels• but what do you do when detected?
• Functional testing only• trick the marker?
• Model answer presented in the lecture
E-marking

• One lecturer (me) in lab for 1 hour, each lab• two 3d year students assist
• they are excellent• they liked it, enjoy the role• more money than stacking shelves
• mentoring• an Edinburgh DAI idea• it happens naturally
Help in the lab

• Contacts• newsgroup, tremendous!
• But hold back. • Let them answer their questions!
• What’s new!• Email, special folder• phone me, from the lab• please don’t come to my office

• Poor attendance• high quality book, notes, slides, demos, etc
• Introduce spot tests• a quick 10 minute question• give user name• get Fiona to capture• use diff to find who is not there
• Repeat randomly• Email those that are absent!

Live Dangerously
• Cut code in the lecture theatre• lapTop and beamer• java and emacs
• You will make mistakes• students love this!
• Tell them what you are thinking• a stream of consciousness
• are you teaching them to think?• Introduce errors!
• Show them how you debug• Expose your 1/2 baked thoughts
• “I want something like this …”• Throw away the perfect prepared answer• Talk, talk, talk, talk ...

1st Year
An interview with Murray Wood Patrick & Quintin
![Page 13: Teaching Programming Strathclyde’s way. A second year course in ADS in Java A 2nd year course algorithms and data structures about 200 students Java 2](https://reader035.vdocuments.net/reader035/viewer/2022070407/56649e415503460f94b32881/html5/thumbnails/13.jpg)
1st Year
The Mark and Murray Show
• 12 credits in 1st year• 2 credits programming in java• 2 credits Organisation/Hardware• 1 credit Apps and Imps• 5 credits maths• 2 credits something else
• 110 CS students• 170 others
![Page 14: Teaching Programming Strathclyde’s way. A second year course in ADS in Java A 2nd year course algorithms and data structures about 200 students Java 2](https://reader035.vdocuments.net/reader035/viewer/2022070407/56649e415503460f94b32881/html5/thumbnails/14.jpg)
1st Year Programming
• 22 weeks• 2 lectures a week• 2 hours lab a week
• marked off in the lab• functional testing• worth 1 mark (tick)
• 9 practicals in first 12 weeks• 1 test in 2 hour lab
• worth 5 marks• 2 more 1 hour tests in second semester• In total, 15 practicals

![Page 15: Teaching Programming Strathclyde’s way. A second year course in ADS in Java A 2nd year course algorithms and data structures about 200 students Java 2](https://reader035.vdocuments.net/reader035/viewer/2022070407/56649e415503460f94b32881/html5/thumbnails/15.jpg)
1st Year Programming
• 3 supervisors to 50 seat lab• lecturer + TA + 4y student
• Sample solution posted each week• Lab exam
• 3 lots of 6 questions • No solutions given out!• 90 minutes to do, last 30 minutes to mark• students can leave when they want• at end, about 10 students left
• 1 written exam• 2 hours• given a piece of code• questions built around this
• OCW if less than 70% in course work• sizeable piece of work

1st Year Programming
• java/oops• lack of emphasis on problem solving• degree is very focussed on java• rationalisation, but some casualties
![Page 19: Teaching Programming Strathclyde’s way. A second year course in ADS in Java A 2nd year course algorithms and data structures about 200 students Java 2](https://reader035.vdocuments.net/reader035/viewer/2022070407/56649e415503460f94b32881/html5/thumbnails/19.jpg)
1st Year Programming
• Course book by Garside and Mariani• Garside and Mariani don’t use it
• Student volunteers helping choose next course book• write one page report• keep the book
• Course is distributed on CD• 50% take CD• pay £3
![Page 20: Teaching Programming Strathclyde’s way. A second year course in ADS in Java A 2nd year course algorithms and data structures about 200 students Java 2](https://reader035.vdocuments.net/reader035/viewer/2022070407/56649e415503460f94b32881/html5/thumbnails/20.jpg)
2nd Year Programming
• 5/6 of 2nd year is CS!• 2 credits on ADS• 2 credits prog project
• problem solving addressed in 2nd year!• C in low level programming course
• no comparative languages course• no ml, prolog, …
![Page 21: Teaching Programming Strathclyde’s way. A second year course in ADS in Java A 2nd year course algorithms and data structures about 200 students Java 2](https://reader035.vdocuments.net/reader035/viewer/2022070407/56649e415503460f94b32881/html5/thumbnails/21.jpg)
Conclusion?
• Different ways to teach CS• specialise on 1 language?• Coding versus problem solving?• Many small or few big exercises• more labs, less tutorials• lab exam
• My way (1998-2000)• performance CS• problem solving as a stream of consciousness
