Conceptualizing professional development in mathematics: elements of a model

This theoretical paper discusses the concept of models for mathematics professional development. After examining the related literature, we propose a definition of this concept that includes four elements: goals, theories, contexts, and structure. We present aspects of professional development that comprise each element

Designing Professional Learning Tasks for Mathematics Learning Trajectories

In this paper, we present an emerging set of learning conjectures and design principles to be used in the development of professional learning tasks that support elementary teachers’ learning of mathematics learning trajectories. We outline our theoretical perspective on teacher knowledge of learning trajectories, review the literature concerning mathematics professional learning tasks, offer a set of initial conjectures about teacher learning of learning trajectories, and articulate a set of principles to guide the design of tasks. We conclude with an example of one learning trajectory professional learning task taken from our current research project

Issue of Virtual Currency by the Central Bank: Monetary Policy and Legal-Economic Aspects in Recent Experience

Indeed central bank digital currency issues is a no return way International experiences on assessing this possibility have been increasing mainly on designing devices for future purposes and also demonstrate deep concern with this issue Based on macroeconomic models this paper aims to discuss how central bank digital currency issues impact monetary policy and how regulation has coped with this still unknown innovation Furthermore it is also our aim to discuss if a recent Brazilian regulation law takes appropriately virtual money issues into accoun

Direito comercial e desenvolvimento econômico

O texto pretende contribuir para a discussão relacionada ao desenvolvimento econômico e o papel ou função de normas jurídicas e/ou sociais. A denominada lex mercatoria, fruto da necessidade de afastar a aplicação do direito comum, criou regras especiais que, aplicadas pelas corporações, geraram confiança e estímulos para o exercício da atividade. Quanto à questão da codificação desse ramo do Direito, estudo de Lisa Bernstein, explica não ser a solução ideal enquanto o de Schäfer e Wulf se volta para a importância da formação de profissionais do direito para dar segurança aos agentes econômicos em suas relações econômicas. A conclusão do texto é de que, sem confiança não haverá investimentos produtivos e que, dessa forma, a legislação, seja a positivada ou a soft Law é essencial para o crescimento econômico. Palavras-chave: Comercial. Desenvolvimento econômico. Relações Econômicas. Abstract: The study aims to contribute to the discussion of economic develpment/ growth and the Law. Startig with the lex mercatória, the discussion goes back to the Middle Age and the contribution of merchants to the development. Reference is made to Bernstein and Schäfer-Wuld studies to demonstrate that codes are not Always necessary but scientifically prepared professional are mandatory. But mainly that with no confidence in the institutions, no investment decisions will be made, harming the society in general. Keywords: Commercial. Economic development. Economic Relations

Edyta Stein w Rosji

In this article a reception of Edith Stein’s philosophy in Russian academic, religious, artistic and medial discourses is presented. The author discusses scholarly elaborations devoted to Stein, her presence in media, libraries and on the Internet. Then, the author analyses the actual state of research, notably feministic and gender approaches, as well as the issue of corporeality, artistic works devoted to Stein and the contents of information services and websites

Diseño de tareas de aprendizaje profesional para trayectorias de aprendizaje de matemáticas

In this paper, we present an emerging set of learning conjectures and design principles to be used in the development of professional learning tasks that support elementary teachers’ learning of mathematics learning trajectories. We outline our theoretical perspective on teacher knowledge of learning trajectories, review the literature concerning mathematics professional learning tasks, offer a set of initial conjectures about teacher learning of learning trajectories, and articulate a set of principles to guide the design of tasks. We conclude with an example of one learning trajectory professional learning task taken from our current research project.En este artículo, presentamos un conjunto emergente de conjeturas de aprendizaje y de principios de diseño para ser empleados en el desarrollo de tareas de aprendizaje profesional que apoyan el aprendizaje de trayectorias de aprendizaje de matemáticas de maestros de primaria. Describimos brevemente nuestra perspectiva teórica sobre el conocimiento del profesor acerca de trayectorias de aprendizaje; revisamos la literatura sobre tareas de aprendizaje profesional, presentamos un conjunto de conjeturas iniciales acerca del aprendizaje del profesor sobre trayectorias de aprendizaje; y articulamos un conjunto de principios para guiar el diseño de tareas. Concluimos con un ejemplo de una tarea de aprendizaje profesional que ha sido tomada de nuestro proyecto de investigación actual.The research reported is based upon work supported by the National Science Foundation under grant number DRL-1008364.

Partnerships and Incomplete Contracts

The legal doctrine contract aims to ensure and to regulate a pacific wealth circulation, and to avoid violence in an efficient allocation of goods in economy and to promote its transfer among people on licit basis. The author treats this assertion and other ones, and observes the profile of commercial partnerships.O instituto jurídico contrato visa assegurar a regular e pacífica circulação da riqueza, a evitar a violência na alocação eficiente dos bens na economia e a promover sua transferência entre pessoas de forma lícita. Essa assertiva e outras são abordadas pela autora que também observa o perfil das sociedades de cunho comercial

Mathematics Professional Development Researchers as Stakeholders

In this paper I argue that since the publication of The Reflective Practitioner (Schön, 1983), mathematics professional development researchers have focused on bringing teachers’ knowledge to the foreground, leaving behind the value of their own research community’s knowledge. I revisit Schön’s criticism of the technical rationality and use examples from my own practice in mathematics professional development to suggest that instead of continuing to reject technical rationality, mathematics professional development researchers should consider a revised version of it to move the field forward: one that values both teachers’ and researchers’ knowledge

Conceptualización del desarrollo profesional en matemáticas: Elementos de un modelo
