Recent researches indicated that students' ability to construct evidence based explanations in classrooms through scientific inquiry is critical to successful science education. Structured argumentation support environments have been built and used in scientific discourse in the literature. To the best our knowledge, no research work in the literature addressed the issue of automatically assessing...
Abstract-Symmetric Loewner-type matrix has broad applications in natural sciences and engineering technologies. Many of the issues are summarized for the sake of symmetric Loewner (type) matrix and its correlation matrix algebraic problem. We present a new fast algorithm of Moore-Penrose inverse for an m??n symmetric Loewner-type matrix with full column rank by forming a special block matrix and studying...
In no science or engineering discipline does it make sense to speak of isolated experiments. The results of a single experiment cannot be viewed as representative of the underlying reality. The concept of experiment is closely related to replication. Experiment replication is the repetition of an experiment to double-check its results. Multiple replications of an experiment increase the credibility...
In scholar curriculum, the integration of contents from different learning areas has been always a challenging issue, but with very few practical experimentations. This paper reports an experimental project of teaching natural science, mathematics, and computer science (technology education) in the first level of the Italian secondary school, by means of a common integrate path based on practical...
