A key question for the understanding of photosynthetic water oxidation is whether four oxidizing equivalents necessary to oxidize dioxygen are accumulated on Mn ions oxygen-evolving complex (OEC), or some ligand-centered oxidations take place before formation and release during S(3) --> [S(4)] S(0) transition. Progress in instrumentation flash sample preparation allowed us apply Kbeta X-ray emission spectroscopy (Kbeta XES) this problem first time. The XES results, combination with...
In recent years the profession of teaching has reached a maturity to point being considered producer own knowledge necessary practice. The teacher is no longer seen as technician, but an intellectual actor and specialized literature advocates profession, it recognizes that “knowledge base”, set skills are developed during his activity. Pedagogical Content Knowledge (PCK) concept seeks represent teachers’ professional been widely used in about teachers' knowledge. It proved fruitful model for...
A key component required for an understanding of the mechanism evolution molecular oxygen by photosynthetic oxygen-evolving complex (OEC) in photosystem II (PS II) is knowledge structures Mn cluster OEC each its intermediate redox states, or S-states. In this paper, we report first detailed structural characterization using extended X-ray absorption fine structure (EXAFS) spectroscopy S0 state, which exists immediately after release oxygen. On basis EXAFS spectroscopic results, most likely...
The oxygen-evolving complex of Photosystem II (PS II) in green plants and algae contains a cluster four manganese atoms the active site, which catalyzes photoinduced oxidation water to dioxygen. Along with Mn, calcium chloride ions are necessary cofactors for proper functioning complex. A key unresolved question is whether Ca close Mn cluster, within about 3.5 Å. To further test verify this finding, we substituted strontium probed from Sr point-of-view any nearby Mn. has been shown replace...
Este estudo investiga as inter-relações entre os componentes do Conhecimento Pedagógico Conteúdo (PCK) de licenciandos em Química participantes Programa Residência Pedagógica (PRP). Adotou-se uma abordagem qualitativa caso, envolvendo a implementação sequências didáticas, reuniões semanais e análises relatórios semestrais. Entrevistas semiestruturadas foram utilizadas com base na técnica reflexão estimulada, fim explorar discutir o planejamento execução das atividades intervenção. Os dados...
The oxygen-evolving complex of photosystem II (PS II) in green plants and algae contains a cluster four Mn atoms the active site, which catalyzes photoinduced oxidation water to dioxygen. Along with Mn, calcium chloride ions are necessary cofactors for proper functioning complex. current study using polarized Sr EXAFS on oriented Sr-reactivated samples shows that Fourier peak II, fits best at 3.5 Å rather than lighter (C, N, O, or Cl), is dichroic, larger magnitude 10° (angle between PS...
A literatura, em especial da área de ensino ciências, tem apontado uma base conhecimentos para professores que delimita e caracteriza essa profissão. Dentre estes, o Conhecimento Pedagógico do Conteúdo (PCK, na sigla inglês), representa conhecimento os utilizam no processo ensino, distinguindo professor dada disciplina um especialista dessa sido considerado modelo frutífero a investigação sobre ciências e, subsidiar currículos propostas formação inicial contínua. Por outro lado, existe pouca...
O presente trabalho tem por objetivo analisar como docentes do Ensino Superior de uma universidade pública percebem os diferentes agentes campo educacional, e as tensões dificuldades são gerenciadas no início da profissão, partindo noção Bourdieu. Nossos dados se basearam em entrevistas semiestruturadas, que foram analisadas Análise Conteúdo. resultados revelam relacionadas à gestão sala aula semelhanças entre professores com sem experiência prévia diz respeito: insegurança didática, ao...
This study aimed to investigate environmental education (EE) in the initial training of teachers chemistry.The data were based on documentary analysis political pedagogical project Chemical Education course, syllabus school subjects, questionnaires and interviews with students.The resulting diagnosis explicitly shows little evidence concern over inclusion EE teacher training.Beginner students showed representations centered recycling awareness.More advanced had sustainability awareness,...
This paper presents a qualitative cross-level study with focus on prospective and in-service teachers’ pedagogical content knowledge (PCK) of redox reactions in Germany. The objective was to investigate analyze the differences PCK between those pre-service teacher education working as teachers. sample included four different groups: bachelor’s students, master’s graduate trainees, Data were collected by an online questionnaire semi-structured interviews. developed based misconceptions...
Assessment of learning plays a central role in the teaching-learning process, and it has been extensively investigated due to recognized necessity adjusting didactic models new curricula social demands. The knowledge assessment is considered one components pedagogical content (PCK) by some authors for other component base teaching. It also strong link between educational ends, goals, purposes values procedures. In this work, results focused on ten chemistry teachers are presented with main...
PCK aspects of Green Chemistry in university chemistry teachers This paper aims to document the pedagogical content knowledge (PCK) about (GC) professors from Institute University São Paulo, experts traditional fields and working different undergraduate degrees — BS Chemistry, Environmental Teachers Education Industrial Chemistry. Data were based on a questionnaire 44 items answered by 26 teachers. Analyzes responses individual collective within areas expertise. In Grossman's model...
In this study the aim was to investigate development of Pedagogical Content Knowledge (PCK) early career chemistry teachers. Two pre-service teachers were followed during a one-semester course and after three-year period as formal high school The data involved teachers´ writings, recordings lessons reflections course. After three years, same content in an actual environment videotaped. then interviewed using videotapes for stimulated recall. instruments Representation (CoRe)...
The learning of teaching starts from the theory, observation practice teacher educators andexperiences as students. aim this research is to elucidate theoretical elements disciplinesand practical aspects trainning action that are incorporated by studentteachers their Pedagogical Content Knowledge (PCK) on subject oxidation-reduction. Forthis we conducted a multiple case study with eight formers and three pre-service chemistryteachers. Data based interviews, CoRe, evaluative materials student...
The objective of this study was to analyze visual representations redox reactions and related content in four Brazilian secondary school chemistry textbooks. aimed identify which were used evaluate how these linked one another the main text. Data analyzed regarding representational levels degree relatedness between different Further analysis focused on intended function images curriculum orientation they indicated. sample comprised 286 representations. results showed that most merely served...
In this study, we investigated the impact of a continuing professional development program (CPD) on pedagogical content knowledge (PCK) chemistry teachers regarding topic redox reactions. For purpose, CPD designed to develop teachers’ PCK reactions was examined. During course, were observed and their activities analyzed. The data collected based responses CoRe instrument, lesson plans, vignettes, audiovisual records program. Qualitative thematic analysis employed analyze data, focusing five...
The textbook has been pointed as one of the most common teaching resources in Brazilian schools, for times occupying a central role teaching-learning process. Therefore, several studies investigate quality books, using different analysis methodologies. This work seeks to present an instrument evaluating textbooks, developed by project 2061 American Association Advancement Science. was used what extent books approved National Textbook Program provide support process redox content. Finally,...
