Epistemic

The main purpose of the present study is to investigate the ways students' instrumentation of Computer Algebra System (CAS) can help promote their algebraic reasoning while solving polynomial inequalities. In addition, the relation between students' CAS techniques and paper-and-pencil (P&P) techniques are explored, together with the difficulties that students may face as they apply these techniques. Research participants are 33 tenth graders at a private mixed gender school in Mount-Lebanon, distributed among nine homogenous groups, five of which are selected as focus groups. The study is qualitative in nature. Data is collected from pretests, students' written solutions of four instructional activities, laptop screen recordings, video recordings of whole-class discussions, and audio recorded interviews with students in the focus groups. The findings of the study show that students' lack of prerequisite knowledge of the topic of functions and their low level of familiarity with GeoGebra software are determinant factors that hinder these students' instrumentation of CAS and hence their reasoning processes as well as their implementation of the solving techniques. High and middle-achieving students' solving techniques acquired little epistemic and some pragmatic values, whereas low achieving students' solving techniques acquired heuristic values.

When embarking on a journey towards the constitution of epistemological semantics one needs to describe clearly the key term ’epistemic’ and differentiate between this term and the term ’cognitive’, which has been used so far, but has in time become ambiguous. The author of this article does not present the history of using these terms. Instead he undertakes to clarify the term ’epistemic’ in order to enable himself to operate on problems linked with making epistemo- logical semantics legitimate, including the problem of using specialized neologisms.

ABSTRACT The idea of global governance has attained near-celebrity status. In little more than a decade the concept has gone from the ranks of the unknown to one of the central orienting themes in the practice and study of international affairs of the post-Cold War period. The intensi-fying connections between states and peoples, better known as global-ization, are now frequently presumed to create the need for governance and rule-making at the global level. According to such a view, only with global governance will states and peoples be able to cooperate on economic, environmental, security, and political issues, settle their disputes in a nonviolent manner, and advance their common interests and values. Absent an adequate supply of global governance, states are likely to retreat behind protective barriers and re-create the conditions for enduring conflict. Global governance, then, is thought to bring out the best in the international community and rescue it from its worst instincts. Although the study of global governance has a long pedigree, its prominence increased dramatically after the Cold War. A scholarly journal now bears its name. Several presses now have series on the sub-ject. Although scholars have been less likely to invest global governance with the same heroic qualities as do policymakers, they have tended to see it as capable of helping states overcome conflict and achieve their common aspirations. For policymakers and scholars, global gov-ernance is one of the defining characteristics of the current international moment..

La modalidad en el espanol hablado en Tunja: tendencia y uso, pretende determinar el uso de la perifrasis verbal, segun la modalidad deontica, epistemica y aletica en discursos narrativos de la comunidad de habla de Tunja. El estudio parte de la identificacion y seleccion de muestras narrativas de las entrevistas del corpus: El espanol hablado en Tunja: Materiales para su estudio. Posteriormente, se identifican las perifrasis verbales, luego se clasifican de acuerdo a la modalidad, paralelamente se hace un analisis de estas segun el criterio morfologico. Finalmente, se establece la frecuencia de uso perifrastico por modalidad, de acuerdo a las variables sociales pre-estratificatorias: generacion,nivel de instruccion y genero.

This paper provides a mapping of the different uses of the word multifunctionality. To explore the diversity of meanings and interpretations, a comparative analysis was conducted through five national case studies in France, the Netherlands, Poland, Spain and Switzerland. The analysis conducted at national level makes it possible to identify eight Concept Oriented Research Clusters (CORCs), based on a relative

The narrative approach to the study of moral development is based on central theoretical assumptions about self that are described in this article. Careful attention to narrative yields an approach in which language plays a much larger role in structuring moral life, generating moral ...

If I could summarize this vast movement in one sentence, I would say we shift from the real world to pure imagination or poetry. And yet this is known as being a lie because, no matter how objective the speaker may be in his looking at the world, he disturbs it by his very looking, he is subjective as soon as he names something or describes something with the words of his language, and the proof of it is that no two persons in the same language or no two languages would describe something absolutely and materialistically objective with the same words, the same sentences, and even the same meanings. But this is beyond our concern here. Let us conclude that to reach absolute objectivity, science has to invent formal languages that are unequivocally referential. And even so, there are great discussions among scientists who use the same formal languages, because each term of these languages covers a concept and infinite discussions may go on forever about these particular concepts.
