Constructivism and education: education as an interpretative transformational process

This paper provides an analysis of the ideas of John Dewey and George Herbert Mead with regards the relationship between experience, meaning, language and thinking. It discusses how experience, meaning, language and thinking are based on the creative and constructive actions of individuals. Unlike what is the case in so-called radical constructivism, it is argued that the actions of the individual should be understood in a transactional way. The paper shows the implication of a transactional constructivism for education, arguing that education is the medium in which the creative and constructive actions of individuals come together in a social environment.     

Terrorism,War, and The Killing of the Innocent

Commonsense moral thought holds that what makes terrorism particularly abhorrent is the fact that it tends to be directed toward innocent victims. Yet contemporary philosophers tend to doubt that the concept of innocence plays any significant role here, and to deny that prohibitions against targeting noncombatants can be justified through appeal to their moral innocence. I argue, however, that the arguments used to support these doubts are ultimately unsuccessful. Indeed, the philosophical positions in question tend to misunderstand the justification of both the prohibition against targeting noncombatants, and that of the permission to attack combatants, for which the paper offers a new account. Such misunderstandings make it all too easy to justify both terrorist actions and morally objectionable actions on the part of nations at war. Taking proper account of the role of innocence in the context of armed conflict will alter our ordinary ways of thinking about the ethics of war, with respect to both jus in bello and jus ad bellum.

True self-love and true self-sacrifice

A philosophical assessment of Richard Dawkins’ The God Delusion, exposing some errors of reasoning that undermine part of the foundation of his atheism. Distinctions between theism, atheism and agnosticism are also provided and explored for their significance to Dawkins’ argument.     

On the Mirror Stage with Henry and Eliza or Play-ing with Pygmalion in Five Acts

This play-ful paper examines the Pygmalion myth as interpreted by George Bernard Shaw in the 1938 film, an adaptation of his 1912 play. This myth of creation is discussed as a cautionary parable for the psychoanalytic treatment situation; mirroring is viewed from the perspectives of Winnicott, Kohut, and Lacan. It is suggested that the wish to create and to be created may play a role in all analyses.     

The functional equivalence of problem solving skills

The tower of Hanoi problem is used to show that, even in simple problem environments, numerous distinct solution strategies are available, and different subjects may learn different strategies. Four major classes of solution strategies are described for the problem. Different strategies have different degrees of transferability, place different burdens on short-term memory and on perception, and require different learning processes for their acquisition. The analysis underscores the importance of subject-by-subject analysis of “what is learned” in understanding human behavior in problem-solving situations, and provides a technique for describing subjects' task performance programs in detail.     

The perception of consistency in attitudes

A study was conducted to test the hypothesis that when people change their attitudes they reduce the dissonance associated with the inconsistency of their new and previous positions by distorting their recall of their initial stand to make it consistent with their new attitude. Small groups of high school students discussed bussing, one of 30 pretested issues. An experimental confederate participated in each session with the task of effecting attitude change. After the discussion, the subjects' new attitudes were assessed and they were asked to duplicate their pretest scores. The results confirmed the hypothesis. Subjects distorted their recall of their initial stand on bussing so as to make it consistent with their new attitude. Such distortion allows persons to feel that their new position is the one they have always held. The subjects made such recall errors only on the bussing issue. Control subjects did not distort their original bussing attitudes.     

Modeling strategy shifts in a problem-solving task

A computer simulation model was fitted to human laboratory data for the Missionaries and Cannibals task to explain (1) the effects upon problem performance of giving a hint, and (2) the effects of solving the problem a second time after one successful solution had been achieved. Most of the variance in the relative frequencies of different moves can be explained by positing that the effect of the hint, or of previous experience in solving the problem, is to cause subjects to switch more promptly from a strategy of balancing the numbers of missionaries and cannibals on both sides of the river, to a means-ends strategy.     

The development of memory structure as reflected by semantic-priming effects

This study was designed to investigate the development of knowledge about categorical and associative relationships as reflected by the presence or absence of semantic priming effects. Kindergarteners and second-graders were shown pairs of pictures, one picture at a time, and asked to name each picture as rapidly and accurately as possible. Picture pairs were of four types which reflected the factorial combination of associative relatedness (high and low) with categorial relatedness (high and low). An analysis of naming times revealed a significant main effect of associative relatedness, i.e., second pictures or “target” pictures in high-associative pairs were named faster than those in low-associative pairs. This reduction in naming latency, or priming effect, was independent of developmental level. However, the effects of category relatedness varied with developmental level, i.e., target pictures in high-categorical pairs were named significantly faster than those in low pairs by second-graders, but not by kindergarteners. These findings are discussed in terms of previous estimates of children's semantic competence.     

Warning signal termination and a feedback signal may not serve the same function

Three experiments were conducted to test the possibility that a feedback signal (FS) and warning signal termination (WST), while equally reinforcing in the avoidance learning situation, reinforce through different underlying mechanisms. The first experiment showed that the reinforcing properties of an FS are reduced more than those of WST when these stimulus changes are made unreliable by the presence of shock following a CR on specified trials throughout acquisition. Experiment 2 confirmed this effect on avoidance performance when only a few punishment trials were administered following asymptotic avoidance acquisition. Experiment 3 demonstrated this effect during avoidance extinction with and without the presentation of punishment trials between acquisition and extinction performance. The results provided no support for the expectancy explanation of avoidance learning and were interpreted as consistent with the assumption that WST reinforces by permitting fear to dissipate and that the FS reinforces through fear inhibition.
