This article discusses and describes the two initial phases provided by a nominated research design of Didactical Engineering – DE. Thus, in view of an interest declared by the teachhing of Complex Analysis – CA, the work emphasizes the elements that hold the potential to constitute the two initial stages of an DE, nomitaded by preliminary and a priori analysis, with emphasis on description and conception of only two problems situations. So, in view of the long heritage of the French tradition in Didactics of Mathematics, also elects the Theory of Didactical Situations – TSD, in complementary character in other to ensure the reasonable control of the didactic mediation, as well as the predictive character of a theorical and conceptual framework for the research, structured for teaching of CA, reproductible and repeatable in any empirical situation of application in academic locus.

Este trabalho apresenta uma proposta de Engenharia Didática - ED que descreve, apenas, as etapas de análises preliminares, análise a priori (e a concepção de duas situações didáticas), que correspondem aos dois primeiros momentos previstos, de modo sistemático, pela ED no campo da Didática da Matemática. O tema envolve uma das formas ou possibilidades de generalização do modelo secular, que prevê a reprodução de casais de coelhos, nomeado por Sequência de Fibonacci – SF. Diante do rico e variado percurso de evolução e sistematização do referido modelo, opta pela generalização de uma fórmula, cuja autoria, envolve informações conflitantes, embora seja mais conhecida, de acordo com os autores de livros de História da Matemática, como fórmula de Binnet ou Teorema de Binnet. A descrição de duas etapas iniciais de uma ED, envolvem elementos que detêm a possibilidade de explorar novas concepções dos estudantes acerca da SF, inclusive, tendo em vista o uso do CAS Maple, num contexto de investigação histórica, assumindo uma perspectiva de ensino afetada pela Teoria das Situações Didáticas – TSD.AbstractThis work presents a proposal of Didactical Engineering – DE, describing just the preliminarly analyzes and  a priori analysis (and the didactical conception´s situations) which correspond to the first two levels in accordance to ED, in the Didactics of Mathematics. The theme involves one way of possibilities to obtain a kind of generalization relative to a secular model, which provides the  couples of rabbits reproduction, namely by Fibonacci Sequence – FS. Before the rich and varied path of evolution and its systematization of this model, it is opted for the  formula generalization, whose authorship involves a conflicting information, however, it is known, according to the authors of Mathematical History, as a Binnet´s formula or the Binnet´s theorem. The description of the two initial research steps involves some elements that have the potencial to explore new conceptions of the students about the FS, even considering the use of  CAS Maple, in a historical research context, supported by the Theory of Didactical Situations – TDS.Keywords: Fibonacci Sequence.

Purpose – The purpose of this paper is to present French Didactique des Mathématiques (DM) to the Lesson Study (LS) community. Design/methodology/approach – This theoretical paper presents the origins of DM in the Theory of Didactical Situations (TDS) by Brousseau. It elaborates about didactical engineering, fundamental situation and other fundamental concepts. It briefly presents other Didactique theories: the theory of conceptual fields, the anthropological theory of the didactic, the joint action theory in didactics and the double approach. It considers importance of the (TDS) and influences over teaching of mathematics. This paper finishes by highlighting the ways Didactique and LS could contribute to each other in a profitable dialogue. Findings – The paper contrasts DM with some LS main features. It highlights the parallels despite fundamental differences in the initial goals of the perspectives. It shows that these differences could lead to productive dialogue by producing more practice-oriented forms of didactical engineering for the first and making teachers’ principles for lessons more explicit for the latter. Originality/value – The paper presents a very quick overview of the parallels between DM and LS. Additionally, this paper gives many accessible references in English for the reader to explore Didactique further.

This paper aimed to explain how students construct the concept of the area of oblique triangles. Through Lesson Study using the Theory of Didactical Situations, the researchers designed a research lesson with the raison d'être of improving the teaching of trigonometry. The research lesson was implemented to junior high school student-participants in a national high school in the Philippines, and was attended by a pool of observers. A priori and a posteriori analyses were conducted to validate the teaching and learning situations. Observations, notes, students’ outputs, and post-lesson discussions and reflections were used in the analysis of didactical situations. After the conduct of the Lesson Study, the following themes emerged: (1) explicit mathematics didactical intentions are essential in analyzing students' constructed mathematical knowledge and learning, and (2) balancing adidactical situation and teacher facilitation allows independent learning for students.

Based on the assumption that human behaviours are mainly affected by physical and animate environments, this empirical research takes the changeful and complex historical district in Tainan to observe wayfinding behaviours. An a priori analysis of the isovist fields is conducted to identify spatial characteristics. Three measures, the relative area, convexity, and circularity, are applied to scrutinize the possible stopping points, change of speed, and route choices. Accordingly, an experiment is carried out to observe spatial behaviours and different influences of social stimuli. Results show that social interactions afford groups and pairs to perform better than individual observers in wayfinding.© 2016. The Authors.

The positive/negative distinction works well in many fields—for example, in mathematics negative numbers hold their own, and in medical pathology negative results are usually celebrated. But in positive psychology negativity should be replaced with positivity for flourishing/optimal functioning to occur. That the designation of the psychological states and processes deemed positive (good/desirable) and negative (bad/undesirable) is made a priori, independent of circumstantial particularity, both intrapersonal and interpersonal, does not seem to bother positive psychologists. But it should, as it results in conceptual muddles and dead ends that cannot be solved within their conceptual framework of positivity and negativity. Especially problematic is an ambiguity I find in positive psychologists’ a priori and a posteriori understandings of positivity and negativity, an ambiguity about constitutive and causal relations that pervades their science and the conclusions drawn from it. By eliminating their a priori dichotomy of positivity and negativity, positive psychologists might well find themselves in a better position to put back together the psychological reality that they have fractured in their ontologically dubious move of carving up psychological reality a priori into positive and negative phenomena. They then might find themselves better placed to “broaden and build” their own science of flourishing.

In this paper we present a new method for the application of data mining tools on the management phase of software development process. Specifically, we describe two tools, the first one based on supervised learning, and the second one on unsupervised learning. The goal of this method is to induce a set of management rules that make easy the development process to the managers. Depending on how and to what is this method applied, it will permit an a priori analysis, a monitoring of the project or a post-mortem analysis.
