Aprender profundamente, aprender a (metalearning) e por toda vida (lifelong learning) são alguns dos novos desafios que sociedade do conhecimento apresenta ao ensino superior. O aumento interesse métodos estratégias inovadoras, alterem dinâmica da sala de aula, tem produzido boas respostas. Esse artigo técnica mapeamento conceitual para favorecer aprendizagem profunda, aproxima o aluno especializado professor. A possibilidade oferecer feedbacks precisos constantes longo processo...
EVALUATING ANALYTICAL DATA.An activity for introducing hierarchical cluster analysis (HCA) and principal component (PCA) during the Instrumental Analytical Chemistry course is presented.The posed problem involves discrimination of mineral water samples according to their geographical origin.Thirty-seven 9 different brands were considered results from determination Na, K, Mg, Ca, Sr Ba taken into account.Non-supervised methods pattern recognition explored construct a dendrogram, score loading...
Abstract. In September 2022, the METHANE-To-Go Africa (MTGA) scientific aircraft campaign, part of UNEP’s IMEO Methane Science Studies, conducted first CH₄ emissions measurements from offshore oil and gas sector in West Africa. This study provides independent empirical data on this previously unstudied region. Emissions Angolan facilities were quantified using an aircraft-based mass balance method, estimating total assessing 30 individual 10 facility groups. Our findings show consistent...
Electroanalytical stripping techniques have been well-used for trace-metal determinations, because of their remarkable sensitivity and selectivity. However, when these are applied organic materials, such as crude oil petroleum-based fuels, the samples must be decomposed. This paper evaluates use different microwave ovens decomposition diesel fuel to determine content copper, lead, mercury, zinc in digestates. A focused-microwave (FM) oven using H2SO4/HNO3/H2O2, operated at atmospheric...
In this paper, we explore the use of concept maps (Cmaps) as instructional materials prepared by teachers, to foster understanding chemistry. We choose fireworks a macroscopic event teach basic chemical principles related Bohr atomic model and matter–energy interaction. During teachers' Cmap navigation, students can experience sense disorientation, which is detrimental learning process. Two graphical cues were tested navigation guidance: (1) colour-coded concepts, group similar content (2)...
Abstract Die Wärmeleitfähigkeit der Gasgemische NH 3 –A, H 2 S–A, SO CH Cl–A, Cl–C 5 Cl, Br–C Cl–Ne, –Ne wurde von 273–1173°K bzw. bis zur Temperatur, bei die Dissoziation nicht mehr vernachlässigbar ist, nach Hitzdrahtmethode gemessen. Meßwerte für reinen Gase , S, und Cl wurden mit den theoretischen Werten verglichen, man aus zwischenmolekularen Kräften Molwärmen Hilfe Ausdrücke erhält, durch Lösung Uhlenbeckschen Stoßgleichung mehratomige erhalten wurde. Relaxationszeit Rotation...
In this paper, the authors break down elements of what it means to be an analytical chemist expose underlying knowledge structures that contribute specialist contextual expertise. An appreciation structure provides first step in designing ways scaffold student development We have identified two critical gaps need bridged for students achieve this: between complementary networked can impede high level understanding (the gap intrinsic and shared fundamentals Analytical Chemistry), networks...
The use of internal standardization for simultaneous atomic absorption spectrometry (SIMAAS) was investigated Cd and Pb determination in whole blood. comparison thermochemical physico-chemical parameters allowed the selection Ag, Bi, Tl as standard candidates. Correlation graphs, plotted from normalized absorbance signals (n = 20) (axis y) versus analyte x), precision accuracy were used to select Ag most appropriate standard. Blood samples diluted (1 + 9) with 0.11% (m/v) Triton X-100 1.1%...
A systematic study of Na+, K+, Ca2+, Mg2+, Cl-, NO3-, SO4(2-) and PO4(3-) interference on the simultaneous atomization As, Cd, Pb Se was carried out using an electrothermal atomic absorption spectrometer. The mixture 250 mg W + Rh thermally deposited graphite tube platform used as permanent chemical modifier. compromised heating program adjustments (Tp = 650ºC Ta 2200ºC) diminished thermal decomposition volatilization efficiency interfering species during pyrolysis step. Cl- anions caused...
O presente trabalho tem como objetivo propor uma nova forma de utilizar os mapas conceituais (MCs) para verificar alunos articulam diferentes materiais instrucionais (MIs) indicados estudo pelo professor. Isso expande a possibilidade uso dos MCs ferramenta avaliação, normalmente restrita à aprendizagem alunos. procedimento proposto requer que incluam informações sobre origem cada um conceitos do MC, em função MIs estudo. (n = 88) astronomia formam o primeiro conjunto dados empíricos ratifica...
Resumo: Os mapas conceituais (MCs) são organizadores gráficos que permitem representar o conhecimento e promover a aprendizagem significativa. A utilização adequada da técnica em sala de aula depende do treinamento dos alunos. Este trabalho teve como objetivo avaliar acompanhar proficiência alunos partir análise estrutura rede proposicional MCs. Para isso foi proposto uso Análise Estrutural 434 MCs produzidos pelos durante disciplina Ciências Natureza na Escola Artes, Humanidades (EACH/USP)...
A busca por novas formas de ensinar e aprender tem colocado os mapas conceituais em evidência, como forma representar compartilhar o conhecimento. Entretanto, tempo requerido para treinar alunos na técnica mapeamento conceitual avaliar produzidos eles é grande demais quando se considera a rotina profissional da maioria dos professores. Uma superar esses obstáculos colocar professor condição mapeador, criando usando seus próprios durante as aulas. Este artigo apresenta quatro diferentes...
A utilização dos mapas conceituais (MCs) como ferramenta de avaliação da aprendizagem foi explorada na disciplina Ciências Natureza, oferecida aos alunos ingressantes Escola Artes, e Humanidades (EACH). Devido à riqueza diversidade das estruturas proposicionais elaboradas pelos alunos, o desafio corrigir MCs é mais complexo do que a correção testes múltipla escolha ou questões dissertativas. Um procedimento comparativo envolvendo professor (P), três especialistas em mapeamento conceitual (E)...
