Evaluation of Scratch VLO for teaching content "density"

Abstract

This qualitative research is part of the project "artifacts in the teaching of natural sciences, especially biology." This first phase aims to relate the technological aspects of design and the fundamental conditions of teaching virtual learning object (VLO). Methodological design was used to study instrumental case where assessment is available to establish the constituent elements of VLO. To do this, the participation of teachers with master's degrees got involved to interact in a real teaching activity with the device and respond interviews with scale items. For the data analysis and comparison Likert scale trend between items, accompanied by a DOFA it was used. The results establish that the categories are related to elements means that lower device design however does not influence the teaching process.
