Narrative-centered learning environments hold significant promise for K-12 STEM education. Much of the appeal of narrative-centered learning arises from the capability of narrative to provide a meaningful structure for integrating pedagogical objectives into a unifying, coherent form that serves as a powerful motivating force for students. This chapter explores the relationship between narrativ...

Um método simples e eficiente foi desenvolvido para a hidrocalcogenação de alquinos contendo um aceptor de Michael (éster, cetona e nitrila) com ânions fenilcalcogenolatos gerados in situ a partir do respectivo dicalcogeneto de difenila (Se, Te, S), usando hidreto de boro e sódio suportado em alumina e meio livre de solvente. Este método é geral e permite a obtenção de ésteres, cetonas e nitril...

Partículas de sílica dopadas com o complexo quercetina-Al foram preparadas através da hidrólise e condensação do tetraetilortossilicato (TEOS) utilizando catálise ácida e básica. A catálise ácida resultou em partículas com diâmetro em torno de 200 nm. A catálise básica com TEOS foi executada sobre um sol de alumina dopado com quercetina utilizado como precursor caroço e com este procedimento fo...

Este estudo apresenta um método novo para ligar moléculas redox ativas derivadas de ferroceno à superfície de silicone monocristalino. O procedimento consiste na reação de silicone hidrogenado com brometo de alila ativado com luz branca e sua reação subseqüente com monolítio ferroceno para criar uma união covalente entre a molécula redox e a superficie do semicondutor. As camadas formadas são e...

Background: Bariatric endoscopic techniques are minimally invasive and induce gastric volume reduction to treat obesity. Aim : To evaluate endoscopic sleeve gastroplasty (Apollo method) using a suturing method directed at the greater curvature, as well as the perioperative care, two year safety and weight loss. Method: Prospective single-center study over 154 patients (108 females) using the ...

identification of the factors causing change in policy process plays an important role in implementing healthy policy process. narrative policy framework introduces new concepts and tools to identify the factors causing policy change. one of the important variables in narrative policy framework is narrative structure. narrative structure has so many elements which the main one is plot. plot lin...

Research in intelligent narrative technologies has recently experienced a significant resurgence. As the field matures, devising principled evaluation methodologies will become increasingly important to ensure continued progress. Because of the complexities of narrative phenomena, as well as the inherent subjectivity of narrative experiences, effectively evaluating intelligent narrative technol...
