TL;DR: It is stated that too many new systems are developed, but also acknowledge the current reasons for the phenomenon, and encourages opening up the existing systems and joining efforts on developing those further.

TL;DR: A study by a ITiCSE 2001 working group established that many students do not know how to program at the conclusion of their introductory courses, and studied the alternative explanation, suggesting that such students have a fragile grasp of skills that are a prerequisite for problem-solving.

TL;DR: A new framework, TRAKLA2, for building interactive algorithm simulation exercises, which supports automatic generation of model solutions as algorithm animations and the logging of statistical data about the interaction process resulting as students' exercises.

TL;DR: This ITiCSE working group report presents the most recent step in the BRACElet project, which includes replication of earlier analysis using a far broader pool of naturally occurring data, refinement of the SOLO taxonomy in code-explaining questions, extension of the taxonomy to code-writing questions, and exploration of a further theoretical basis for work that until now has been primarily empirical.

TL;DR: It is suggested that the Rainfall Problem is not necessarily overwhelmingly difficult: Success rates vary and some reasonably good results have been achieved under multiple programming paradigms.
