• Resumen

  • Both formative and summative assessment may take many forms. Oneapproach, known as “many small programs”, consists of providing many programming exercises per week to students, so that they may exercise the differentconcepts and skills of the course. Different kinds of exercises have been proposed, some of them general purpose, some of them specific to programming.For the latter, the programming paradigm has a decisive influence on the designof these exercises, and even on the feasibility of designing them. In this context,block-based programming represents a new challenge, because the execution stateof block-based programs does not depend on such tangible elements as variablecontents or reducible expressions. Although some block-based languages allowdeclaring and using variables, the most relevant elements of the execution statehave a visual nature. In the paper, we review several taxonomies of programmingexercises and block-based questionnaires to propose a range of exercises specific to block-based programming. Our experience in developing these kinds ofexercises also is reported. The proposal does not intend to constitute a novel andcomplete taxonomy, but an initial effort in the design of programming exercisesfor this programming paradigm.
