ResumoEste artigo apresenta os resultados de uma investigação voltada para o papel da congruência semântica na elaboração de problemas aditivos por alunos, à luz das ideias de Raymond Duval, relacionadas ao desenvolvimento do pensamento algébrico. A pesquisa foi realizada a partir da aplicação de um instrumento de coleta de dados a noventa e quatro alunos do sétimo, oitavo e nono anos de escolas públicas, com o objetivo de analisar a manifestação do fenômeno da congruência semântica na atividade de elaboração de problemas. Neste artigo, apresentamos uma análise das respostas dos alunos para uma questão que solicita a elaboração de problemas. Os problemas elaborados pelos alunos apresentam a estrutura do campo conceitual de problemas aditivos de Gérard Vergnaud. Os resultados encontrados evidenciaram que a essa proposta, além de apresentar contribuições para o desenvolvimento do pensamento algébrico, enfrenta o fenômeno da congruência semântica, que não pode ser ignorado. Para elaborar problemas, conforme a proposta de Duval, é preciso levar em consideração o fenômeno da congruência semântica, que se reflete diretamente na designação das relações algébricas oriundas dos encaminhamentos das soluções dos problemas.Palavras-chave: Pensamento algébrico, Álgebra, Ideias de Duval.AbstractThis article presents the results of an investigation focused on the role of semantic congruence in students' elaboration of addictive problems, in the light of Raymond Duval’s ideas, related to the development of algebraic thinking. The research was carried out from the application of a data collection instrument to ninety-four students from the seventh, eighth, and ninth grades of public schools, aiming to analyze the manifestation of the phenomenon of semantic congruence in the activity of elaboration problems. In this article, we present an analysis of the students' answers to a question that requests the elaboration of problems. The problems that the students elaborate present the structure of Gérard Vergnaud’s conceptual field of additive problems. The results showed that this proposal, besides contributing to the development of algebraic thinking, faces the phenomenon of semantic congruence, which cannot be ignored. To elaborate problems, according to Duval’s proposal, it is necessary to consider the phenomenon of semantic congruence, which is directly reflected in the designation of algebraic relations arising from the forwarding of solutions to problems.Keywords: Algebraic thinking; Algebra, Duval’s ideas.ResumenEste artículo presenta los resultados de una investigación centrada en el papel de la congruencia semántica en la elaboración de problemas adictivos por parte de los estudiantes, a la luz de las ideas de Raymond Duval, relacionadas con el desarrollo del pensamiento algebraico.

As participant recruitment and data collection over the Internet have become more common, numerous observers have expressed concern regarding the validity of research conducted in this fashion. One growing method of conducting research over the Internet involves recruiting participants and administering questionnaires over Facebook, the world’s largest social networking service. If Facebook is to be considered a viable platform for social research, it is necessary to demonstrate that Facebook users are sufficiently heterogeneous and that research conducted through Facebook is likely to produce results that can be generalized to a larger population. The present study examines these questions by comparing demographic and personality data collected over Facebook with data collected through a standalone website, and data collected from college undergraduates at two universities. Results indicate that statistically significant differences exist between Facebook data and the comparison data-sets, but since 80% of analyses exhibited partial η2 < .05, such differences are small or practically nonsignificant in magnitude. We conclude that Facebook is a viable research platform, and that recruiting Facebook users for research purposes is a promising avenue that offers numerous advantages over traditional samples.
