In the interest of stimulating alternatives that counteract a teaching reality that leads Brazilian students, especially from public schools, to a lack of knowledge, Teachers College-Columbia ...University, in partnership with the Lemann Foundation, invested in strengthening the performance of Brazilian researchers, launching the notice “Researching Teaching and Learning: An Equity Imperative for Teacher Education”. Contemplated in this notice, the Center for Investigations, Development and Study of Games in Education (NIDEJE) proposed to investigate how situations of discursive interaction provided using didactic games can be a factor of change in a teaching scenario, in which doubts, and errors are disregarded as opportunities for (re)signifying understandings. For this, the didactic game “Guess Which?” was applied in a public high school in the Pernambuco countryside, the first application of the didactic game with the exclusive participation of students who had difficulties in the content of organic functions and the second application with groups composed with some students who had difficulties and others who had better academic performance in the chemistry subject. The externalization of students' thoughts in their planning, discussions, and reflections that occurred during the game were recorded and later analyzed through microgenetic analysis. In this way, we analyze the discursive interactions provided by the zones of imminent development (ZID) formed in the groups and the implication of the constitutions of the groups in the dynamics of this ZID and in the students' awareness of their mistakes being revisited. Finally, we observe that the didactic game can involve and motivate students to a collective action, which encourages them to make justified choices. Thus, they provide a favorable environment for reflections on the application of concepts and awareness not only about them, but also about their mistakes and difficulties, which helps them to overcome them. The quality of these reflections is favored by the ZID formed by students and professors by promoting the review of positions, justifications and resignifying concepts and procedures. We also emphasize that the role of the teacher as an interlocutor in the ZID grows in relevance when the constitution of groups is formed exclusively by students with more difficulty in the content.

The external facades of a building are more than a protective mantle, or an intelligent skin regulating temperature and light, they also determine its very appearance. By unusual choices of materials ...and the use of complex technology, facades have become increasingly significant in recent years. External surfaces are being perceived as an integral part of the building and are therefore being designed as such. This volume focuses on the wide-ranging aspects of facade design, from the selection and use of materials to the advanced technical possibilities now open to the architect. A wide array of carefully selected international examples show the theory in the practice. All plans, details, and large scale sections of the facades have been researched with the high degree of competence typical of the editorial staff from the review Detail. Expert authors provide the essential information needed to plan and design facades and elucidate on the latest developments in technology and materials.
Příspěvek je věnován opevnění mocenské aglomerace Staré Město – Uherské Hradiště, jednoho z nejvýznamnějších center raně středověkého státního útvaru, Velké Moravy. Ve studii je vyhodnocen jeden ze ...starších, dosud nepublikovaných terénních výzkumů, které se uskutečnily na východním okraji aglomerace v hradišťské čtvrti Rybárny. V průběhu těchto výzkumů byly objeveny zbytky mohutné fortifikace tvořené čelní kamennou zdí a dřevo-hliněnou konstrukcí táhnoucí se v délce bezmála 400 m. Průběh opevnění byl potom ověřen geofyzikálními i geologickými metodami. Následně došlo v poloze Rybárny k objevu velkomoravského pohřebiště a pravděpodobně i kostela, což kromě jiného vyvolalo nové otázky vztahující se k charakteristice, funkci a dataci nedaleké hradby.
The article is devoted to the fortification of the powerful Staré Město – Uherské Hradiště agglomeration, one of the most important centres of the Early Medieval state formation – Great Moravia. The study evaluates an earlier, hitherto unpublished, excavation that was conducted on the eastern edge of the agglomeration in the quarter Rybárny. During this excavations the remains of massive fortifications were discovered, with a stone facing and an earth and timber structure running a length of no less than 400 m. The course of the fortification was subsequently verified using geophysical and geological methods. Later, a Great Moravian cemetery and probably church were also found at Rybárny, which amongst other things raised news questions relating to the characteristics, function and dating of the nearby rampart.
