Using learning principles as a theoretical framework for instructional consultations

Learning theory provides a powerful framework for analyzing instructional consultations and increasing their effectiveness. In this paper, the authors review the main tenets of learning theory, apply them to consultation scenarios, and present a complex case study to show how they can guide analysis and problem solving around challenging consultations.     

Productive Usability: Fostering Civic Engagement and Creating More Useful Online Spaces for Public Deliberation

This article offers productive usability as a usability approach that focuses on the usefulness of civic Web sites. Although some sites meet traditional usability standards, civic sites might fail to support technical literacy, productive inquiry, collaboration, and a multidimensional perspective—all essential ingredients for citizen-initiated change online. In this article, we map productive usability onto broader philosophies of usability and offer a framework for rethinking usability in civic settings and for teaching productive usability.     

俄罗斯方块的心理效应

Shapes fall from the sky,all you have to do is to control how they fall and fit within each other.A simple premise,but added with an annoyingly addictive electronica (电子音乐) soundtrack (based on a Russian folk tune) and you have a revolution in entertainment. Fascinating Tetris 令人着迷的俄罗斯方块 Since Tetris was launched on the world in 1986,millions of hours have been lost through playing this simple game.Since then,we've seen games consoles(便携型游戏机)grow in power,andwith it the appearance of everything from Call of Duty(游戏名,"使命的召唤")to World of Warcraft(游戏名,"魔兽世界").Yet block and puzzle games like Tetris still have a special place in our hearts.Why are they so compelling?     

Electrochemical analysis of the degradation of lead alloy organ-pipes due to acetic acid

Lead is commonly used for making small size organ-pipes instead of using tin alloys. In fact, when the organ-pipes are small enough to avoid collapsing due to room temperature creep, lead can be used instead of other alloys with superior mechanical properties, because it is relatively cheap, it is easy to form into different shapes, the tonality of the obtained sounds are acceptable and the corrosion resistance is quite good. However, organic substances such as organic acids released from the wood made support of the organ-pipes and organic contaminations of the air pumped through the pipes may lead to a rapid degradation of lead. In this study, the effect of organic acids, such as acetic acid, on the degradation of lead-made organ-pipes was investigated. Lead made specimens obtained from real organ-pipes were exposed to organic-acid rich environments and the induced degradation was monitored by means of electrochemical techniques. In literature, it was evidenced that the degradation promoted by the organic acids leads to the formation of lead oxides and carbonates characterized by a very high volume, which promotes a quick degradation of the lead specimens. The effect of different concentrations of acetic acid on the degradation rate of the organ pipes was investigated by means of electrochemical impedance spectroscopy (EIS). The effect of the acid concentration on the corrosion process occurring on lead surface was evaluated by means of cathodic and anodic polarization measurements in both aerated and degassed conditions. The morphology of the degradation products was investigated by means of SEM during exposure time in the aggressive environment.     

The relationship between behavioural integrity,competence, goodwill,trustworthiness, and motivating language of a principal

Utilising the oral language of a principal leading an inner-city at-risk elementary school in a large urban school district in the southwestern USA, the researchers tested behavioural integrity and the dimensions of source credibility (competence, goodwill, and trustworthiness) as antecedents to Motivating Language Theory and the ML Model. Teacher perception data at the Title I elementary school was used for this quantitative study. Over 95% of the teachers responded to a survey each year for a three-year period. Each year, there were statistically significant correlations between each of the antecedents and motivating language. The antecedents accounted for 66–75% of the total variance for motivating language depending on the year based on regression analysis. The results of this study extend the field of Motivating Language Theory and the ML Model, and further explain how the work of principals is accomplished.

Scientific Phenomenology in Design Pedagogy: The Legacy of Walter Gropius and Gestalt Psychology

This article examines the contribution of scientific phenomenology in design pedagogy through the theoretical relationships between the German art school Staatliches Bauhaus and the most important scientific phenomenological theories of the first half of the twentieth century. After showing the relationships between the Gestalt Theory and the principal teachers of the Bauhaus (Johannes Itten, Paul Klee, Wassily Kandinsky, László Moholy‐Nagy, Josef Albers), the pedagogical epistemology of Walter Gropius is critically presented. The epoché, the intersubjective criterion and the anti‐psychologism are examined. In conclusion, it is evidenced that Gropius was strongly influenced by Gestalt psychology. This undeclared influence was a necessary consequence of the fact that phenomenological attitude is a crucial operating modality for the concrete practice of design.
