Research on the Application of Augmented Reality Technology into the Educational Activities of Kindergarten’s Number Concept

Augmented Reality (AR) is different from virtual reality (VR). It is an emerging technology that does not emphasize the creation of virtual feelings through virtual objects, but focuses on combining virtual objects with real environments. This article starts from the connotation interpretation and characteristic analysis of augmented reality technology, and examines the current kindergarten number concept education activities, and finds that there are the following problems in kindergarten number concept education activities: insufficient creation of mathematics environment, single learning methods for children, and lack of effective learning among children interactive. Combining the characteristics and functions of augmented reality technology, we propose optimization strategies for optimizing kindergarten math concept education activities, respectively creating a unity of “form” and “body” for the environment, rich game experience and dialogue-creating-meaning construction of children’s mathematics cognition.

Meanings that engineering students confer to the antiderivative

In this article, are presented the results of a questionnaire designed to evaluate college students’ understanding of the antiderivative. Specifically, by civil engineering students when answering the questionnaire tasks, in order to identify and characterize the meanings on the antiderivative that are developed by them. In order to analyse the answers given, were used some theoretical and methodological notions provided by the theoretical model known as the Onto-Semiotic Approach (OSA) of mathematics cognition and instruction. The results show the knowledge of antiderivative by the Civil Engineering students. Furthermore, the comparison between the mathematical activity of students provides information that allows concluding that the meanings that they mobilized might be shared among their communities
