The effect of explanations on mathematical reasoning tasks

Studies in mathematics education often point to the necessity for students to engage in more cognitively demanding activities than just solving tasks by applying given solution methods. Previous studies have shown that students that engage in creative mathematically founded reasoning to construct a solution method, perform significantly better in follow up tests than students that are given a solution method and engage in algorithmic reasoning. However, teachers and textbooks, at least occasionally, provide explanations together with an algorithmic method, and this could possibly be more efficient than creative reasoning. In this study, three matched groups practiced with either creative, algorithmic, or explained algorithmic tasks. The main finding was that students that practiced with creative tasks did, outperform the students that practiced with explained algorithmic tasks in a post-test, despite a much lower practice score. The two groups that got a solution method presented, performed similarly in both practice and post-test, even though one group got an explanation to the given solution method. Additionally, there were some differences between the groups in which variables predicted the post-test score.     

Toy Models of Top Down Causation

Models in which causation arises from higher level structures as well as from microdynamics may be relevant to unifying quantum theory with classical physics or general relativity. They also give a way of defining a form of panprotopsychist property dualism, in which consciousness and material physics causally affect one another. I describe probabilistic toy models based on cellular automata that illustrate possibilities and difficulties with these ideas.     

Communication and the thesis of intentionality in Husserl,Sartre, and Levinas

Review and discussion of the thesis of the intentionality of consciousness are relevant to inquiry into the experience of human communication. Development of the thesis of intentional consciousness is traced from the work of Edmund Husserl (transcendental phenomenology) to Jean-Paul Sartre (existential phenomenology), to Emmanuel Levinas (phenomenology of communication ethics). Insight is offered into the relevance of the thesis of intentionality to the phenomenological roots of three thematics in human communication inquiry: (1) conscious awareness; (2) self-understanding; and (3) the communicative foundation of self–other relating.     

Preface

<正>The past decade has witnessed the significantly increasing impact of the Chinese chemical community worldwide and the Chinese chemists are playing an irreplaceable important role.This is reflected by not only the increased number but also the improved quality of scientific publications.Some top level original works have opened new fields

Sol–Gel Processed Functional Nanosized TiO2 and SiO2-Based Films for Photocatalysts and Other Applications

Titania and silica-based porous coatings have been produced via sol–gel route in the presence of pore-creating agents PEG and viscous solvent -terpineol, or template agents CTAB, as well as triblock copolimer Pluronic P123. Porous titania films were characterised by HR TEM, UV-Vis, XRD, ellipsometry, ARS methods. The dispersion of the refractive index, the porosity (32–39%) and the thickness of the samples were estimated by integrating sphere transmission and reflection spectra with 3D angular resolved light scattering. The catalytic activity of mesoporous TiO₂ and TiO₂/ZrO₂ as well as SiO₂-benzophenone films in the process of Cr^VI to Cr^III and Ag⁺ to Ag⁰ photoreduction have been studied.     

电视综艺导演的节目推广意识与实践

在全媒体时代中,电视台对于电视节目的制作也发生了很大改变,电视节目的导演也一定要将节目推广的意识结合到电视节目当中,这样才可以满足现在全媒体时代的要求。电视综艺节目的导演一定要将推广意识放到电视节目播出之前,这样才可以体现出综艺节目的内涵,促进综艺节目的发展。根据电视综艺节目导演的推广意识与实践进行研究。
