Feedback services for stepwise exercises
Advanced learning environments such as intelligent tutoring systems for algebra, logic, programming, physics, etc. let a student practice with stepwise exercises, and support a student solving such exercises by providing feedback. These environments usually provide various types of feedback, for example about the correctness of a step, common errors, hints about how to proceed, or complete work...
متن کاملStrategy-based feedback for imperative programming exercises
syntax. An abstract syntax has been designed to represent imperative programs, supporting the language constructs of Table 8. This abstract syntax is implemented using data types in Strategy-based feedback for imperative programming exercises 34 Haskell, in which a Program is the top-level type that consists of zero or more statements. The Statement data type represents the various program stat...
متن کاملFeedback Services for Exercise Assistants
Immediate feedback has a positive effect on the performance of a student practising a procedural skill in exercises. Giving feedback to a number of students is labour-intensive for a teacher. To alleviate this, many electronic exercise assistants have been developed. However, many of the exercise assistants have some limitations in the feedback they offer. We have a feedback engine that gives s...
متن کاملStrategy Feedback in an E-learning Tool for Mathematical Exercises
Exercises in mathematics are often solved using a standard procedure, such as for example solving a system of linear equations by subtracting equations from top to bottom, and then substituting variables from bottom to top. Students have to practice such procedural skills: they have to learn how to apply a particular strategy to an exercise. E-learning systems offer excellent possibilities for ...
متن کاملSilhouette-based human pose analysis for feedback during physical exercises
In this paper I propose a computer vision-based method for analyzing the human pose during physical exercises performed for a virtual trainer. Body part labeling and difference analysis between a measurement and reference silhouette are combined into a result consisting of a set of vectors per body part, indicating the errors made. The approach depends heavily on a statistical model of the huma...
