Description

Ask-Elle is a web-based intelligent tutoring system developed for teaching first-year computer science students Haskell through strategy-based model tracing, property-based testing, and automated hints.

Components

• Class 3 programming exercises with teacher-configurable feedback and flexibility: Ask-Elle offers class 3 programming exercises, which can be solved by applying alternative solution strategies, in contrast to class 1 exercises with a single correct solution and class 2 exercises with different implementation variants of a fixed strategy. Teachers add exercises by providing model solutions and a configuration file, and can use annotations (DESC, FB, MUSTUSE, ALT) to adapt feedback and control which implementations are accepted. This design allows teachers to accept or reject solutions based on different model solutions, such as an inefficient but simple recursive solution. (Gerdes et al. (2016))

Claims

• In log analysis of 3466 interactions, 56.1% of interactions and 46.3% of attempts were recognised as correct model solutions [+W]
• Strategy-based assessment recognised 62 of 72 correct student programs (86%) from four model solutions with no false positives [+W]
• Strategy-based assessment statically determines which solution strategy a student used and guarantees correctness of recognised programs [+W]
• Compiler errors accounted for over half of diagnosis interactions in the log analysis [+W]
• Students rated the tutor 3.4 out of 5 overall and particularly liked the worked-out solution feedback [+W]
