The present study investigated the process of conceptual reconstruction fraction as a measure of length in the context of a Mathematics Laboratory Education (LEM) when the process is driven by a structured writing activity and mediated intervention of a teacher. To this end, the concepts of LEM were presented, choosing one as the design used for the survey. LEM offers possibilities that the teacher and students as an area of knowledge production, directing for Teaching Activities for which subsidized by Historic-Cultural Psychology, justifies the pedagogical activity of teachers and presents Guiding Teaching Activities were explored as an alternative to minimize some difficulties in teaching and learning, emphasizing conceptual learning. Structured with a class of 40 students in the 6th grade of elementary school in a public school in Belém, which was recorded on video and audio, for later microgenetic analysis of the interactions between teacher and students activity was applied. Taking into consideration the prior knowledge of students, work with the class during the year and structured activity, the results showed evidence of at least ten specific learning had an exponential effect on later learning. This means that the more previous connections are possible to be mobilized by the students in their interactions with the teacher, the more the subject is able to move forward in the consolidation of the object of study.

Jogos concretos no laboratório de ensino da matemática na formação de professores na educação à distância

The present work deals with a methodological proposal for mathematics teachers practicing, which came out from a testing made in the Math Teaching Lab (MTL), of the Universidade Aberta do Brasil (UAB), in Cametá, during tutorial supervised training classes, with students from mathematics distance course. MTL was created in 2013, yet a little explored at initial formation of math teachers, however. The main goal of this work is to present and orientate future teachers of math by the use of some didactic materials from MTL, its reproduction through alternatives materials (junk metal) as well. This research is focused on the Concepts Fields Theory of Vergnaud (1990), also claimed by Pais (2008 and 2011); Kamii (1992), who deals with mathlogic knowledge construction; Alves(2001) and Dohme (2011), who talks about the use of solid games; Yus (1998) and Gonçalves (2005 and 2011), who hold reflexive teachers formation and Lorenzato (2006), who claims about MTL. We also emphasize the research production construction (didactic book) elaborated from a solid game (balance form) of MTL/UAB/Cametá, PA. The students of UAB/2011 class were involved at the workshops. The research has qualitative approach on search-action form, because we developed field activities that began meeting the space of MTL, gathering to experimentation workshops using four solid games from MTL (geo-plain, fractional ruler, balance form and space figures). At the end of this research, interviews were made, in order to identify the comprehension of the college students as the concepts studies, contents and transversal themes by the manipulation of the games. For the second workshop, we built alternative materials from games used on the first one to be used at the period discipline regency and at future teachers practicing. The results of this teaching proposal point out the need of significant exploration of new trends for Mathematics Education during initial formation of math teachers. Among them we presented concrete games, as well as, exploration over other pedagogical spaces instead of a classroom. Here, we mentioned the use of MTL, and was possible to check during workshops, great interest of the students to develop their studies at this place, which makes us think about this place as an important contribution for math teaching, as college studies as basic education.
