Karen Petrie, University of DundeeTeaching Students how to Teach Themselves
Our Challenge• Computing moves incredibly quickly• Programming languages move on• We need to teach students how to learn new
programming languages– Not just what is currently in vogue
Ideally
• Two weeks with a good textbook and a compiler, should be enough for them to be proficient in any language.
How Difficult is this?
• Imagine you have spent all of your life in one area of the UK, you know one dialect of English.
• Now you time travel to Shakespearean England.
• How easy would it be to communicate?
Programming• This is about how difficult it is to change from one
programming language to another
Apart from....
• People speaking Shakespearean English are likely to be a lot more helpful than a computer
• Computers require you to type in precisely the correct language!
Curriculum• In1st year we concentrate on teaching
students to programme for the 1st time. – JAVA
• In 2nd year we concentrate on building these programming skills and learning new languages– C– C++
Links• There are links between JAVA and C++– Same keywords
• C++ is a superset of C• We want students to see these links and work
out how to use them to learn languages• This has been added as a learning outcome of
the 2nd year module
Approach• Teach the new language conventionally
through lectures and practicals– We are trying to get students to spot and
use the connections to previous languages for themselves
• Introduced tutorial for this purpose
Weekly Tutorial• After lectures, but before practical session• Small groups of 5 students• Each student has to write-up a blog post of 2
tutorial discussions, worth 5% each– Meaning at the end the group has a blog
spanning the whole course (10 weeks)• Students loose 1% for every week they do not
attend
Tutorial Content• For every concept you have learnt this week,
discuss how it differs from previous languages you have learned.
• Are there any overlaps between your courses this week?
In the Discussion and Blog Posts
• All students found connections• The easiest ones to find were when the
concepts are the same or similar• Surprisingly, students struggled the most
when concepts were completely different• More successful students dug a bit deeper
and discussed the connections in more detail
Exam Question• Students were given a snippet of JAVA code,
they had to write in both C++ and C. • They then had to compare in detail all three
sets of code• The final question was: How can studying the
differences between syntax and semantics in small code snippets (such as the exercise above) aid in learning new languages?
Results• This exam question was the best answered
question in the exam in 2011 and 2nd best in 2012• The 2011 group all passed Games Programming in
2012.– Many of them taught themselves a new language
to do so.
