Resources for Self-Assessment in the Virtual Mathematics Laboratory

Summary/Abstract: The paper considers various resources for self-assessment developed and maintained in the Virtual Mathematics Laboratory, including files and specific topics. The self-assessment files are related with one-step problems for direct application of definitions, algorithms, properties or with exploratory type of problems. Several models for constructing specific examples of a given type of problems are presented and discussed. Different modes of manipulation for assigning values to the parameters for constructing a new example are considered: using a scroller, entering a number value, moving an object to change the measures of the elements of a geometric construction, etc. An automatic generation of examples for self-assessment by means of random choice of elements of a set of objects is illustrated. Several models for getting a feedback are considered. The structure of a part of themes for self-assessment is described together with the themes, requiring the use of several technologies. The direct request to the user for grading her performance herself is discussed in the context of the forming of competences for self-evaluation. The resources of past issues of the online contest “VIVA Mathematics with a Computer” are discussed in the context of self assessment. The educational function of the self-evaluation by means of the help facility in the dynamic files is emphasized on. The motivating effect being enhanced in the context of fine arts, real situations and serious games, is pointed out. The experience with the use of the digital resources for self-assessment shows so far that the endeavor for: variety, simplicity of operations, creating playful atmosphere when possible, development of digital and mathematical competences, has been crucial and well justified.
