Q4395938 Biologia
Durante uma aula do Ensino Médio, foi proposto aos estudantes o cruzamento entre duas linhagens puras de ervilhas, uma com sementes amarelas e outra com sementes verdes, nos mesmos moldes desenvolvidos por Gregor Mendel. Após obterem a geração F1, os estudantes realizaram a autofecundação dos indivíduos heterozigotos e observaram a esperada proporção fenotípica da geração F2.

Para explicar o resultado obtido, destaca-se um princípio fundamental da genética clássica:

    Central to an approach or method in language teaching is a view of the nature of language, and this shapes teaching goals, the organization of the curriculum, and the emphasis given in classroom teaching. A lexical approach in language teaching refers to one derived from the belief that the building blocks of language learning and communication are not grammar, functions, notions or some other unit of planning and teaching but lexis, that is, words and word combinations. The lexical view holds that only a minority of spoken sentences are entirely novel creations and that multiword units functioning as ‘chunks” or memorized patterns form a high proportion of the fluent stretches of speech heard in everyday conversations.

     Collocations are ‘language chunks’ that form an integral part of any discourse, written or spoken. The term refers to the regular occurrence together of words. For example, compare the following collocations of verbs with nouns:

    Do my hair/ the cooking /the laundry/ my work

    Make my bed/ a promise/ coffee/ a meal

    Notional-functional syllabuses (hereafter referred to as NFS) began to be used in the United Kingdom in the 1970’s. The distinguishing characteristics of the NFS were its attention to functions as the organizing elements of English language curriculum, and its contrast with a structural syllabus in which sequenced grammatical structures served as organizers. Thus, the NFS focused strongly on the pragmatic purposes to which we put language. Curricula were then organized around such functions as identifying, reporting, denying, accepting, declining, apologizing, etc. Some seventy different language functions were identified.

    The NFS quickly provided popular underpinnings for the development of communicative textbooks and materials in English language courses. It is important to emphasize that the NFS did not necessarily develop communicative competence in learners because, as a syllabus, it still presented language as an inventory of units – functional rather than grammatical units, but units nonetheless. Communicative competence implies a set of strategies for getting messages sent and received and for negotiating meaning as an interactive participant in discourse, whether spoken or written. It pressuposes the learners’ ability to “know how to do” things, being able to act in different situations as they put their constructed knowledge into practice.

What makes a teacher


    The idea that if you know something, you can teach it, may seem a straight line. For a gifted few, it might be. But many experts argue that teaching children and young people requires knowing how to teach the content to achieve understanding that is useful to actual learning.

    Knowing how to teach children and young people means having in-depth knowledge of pedagogy (varied philosophies of learning and teaching), assessment, learning styles and needs — and the varied complex dynamics that dictate the context for how effective teaching happens. This fundamental knowledge happens alongside opportunities to practise and refine one’s teaching skills.

    This is the difference between being taught by qualified teachers and by people who know stuff. Knowing content is not synonymous with good teaching. Getting teachers into classrooms faster may fill classrooms, but at what cost? There is a cautionary tale here worth paying attention to.

    Shortening, and in some cases not requiring teacher education at all, has been tried and failed. Studies have shown that a major predictor of student achievement is the preparedness of teachers. For teachers who have entered into classrooms via expedited pathways, evidence showed negative impacts for all student groups.

     I fear we are on a road of short-term gain for long-term pain.

   In any society, a well-trained certified workforce supports continuity of learning and achievement. We wouldn’t contemplate having an unqualified doctor treat us any more than we want an uncertified electrician wiring our house. So why is an unqualified teacher OK? Our children deserve better.
