We report on one aspect of a longitudinal study which seeks insight into the ways in which spreadsheet experience and teachers' pedagogic strategies shape pupils' construction of meaning for algebra. Using data from stimulated recall interviews we analyse the evolution of meaning for variable through the mediation of the variable cell and the…

This study had two purposes: (1) to determine when children distinguish ambiguous from precise messages and when they can resolve ambiguity through additional questioning, and (2) to identify whether implicit messages were more difficult to identify than explicit ones. All children found ambiguous messages significantly more difficult to…

Literature is examined for its metaphors for teaching and teachers, including the teacher as custodian and steward of knowledge, as sower of knowledge, and as "trickster," a picaresque, mythical figure who offers solutions, often inadvertently. The roles of kindness and cruelty in the learning/teaching process are also considered. (MSE)

Integrates the results of a formalist discourse analysis of Freire's "Pedagogy of the Oppressed" with field observations of his programs in Latin America. Identifies some features of Freire's discursive construction of knowledge. Documents the practice of Freire's rehumanizing discourse within consciousness-raising programs in both…

The use of cellular automata to analyze several pre-Socratic hypotheses about the evolution of the physical world is discussed. These hypotheses combine characteristics of both rigorous and metaphoric language. Since the computer demands explicit instructions for each step in the evolution of the automaton, such models can reveal conceptual…

An understanding of the importance of metaphors and beliefs in the development of teachers' practical knowledge has already been explored in science education research. However, the significance of "emotion metaphors" and the consequences of "emotional labor" as part of being a science teacher have been little addressed. This study describes the…

The study describes the nature of pre-service teachers' idiosyncratic metaphors for the concept of statistical sample. These metaphors were investigated because of their potential to provide insight about individuals' content knowledge and how that content knowledge is enacted during teaching. Personal metaphors were elicited from 54 pre-service…

Being a first-year teacher in New York City is not easy. The author received much of the same preparation and advice that he and his colleagues give their students. But even the best education courses and a positive student teaching experience do not seem to be enough to take the edge off of a year he remembers barely surviving. The author…

This paper proposes a methodology to calculate both the difficulty of the basic problems and the difficulty of solving a problem. The method to calculate the difficulty of problem is according to the process of constructing a problem, including Concept Selection, Unknown Designation, and Proposition Construction. Some necessary measures observed…

Education in China, in its various forms and levels, is widely conceptualised as integrating the cultivation of "human souls" with the provision of students with knowledge. The English word "education" is "jiao yu" in Chinese, which means "teaching [and] cultivating". The analogy "shi nian shu mu, bai…

The purposes of this paper are twofold. First, we argue that the rationalistic assumptions on which dominant conceptions of the coaching process rest are rather unrealistic. We therefore hold that they have relatively limited potential either for a theoretical understanding of coaching or for guiding practitioners. Second, we tentatively offer the…

The role and performance of the engineering and scientific institutions in the UK have been undergoing gradual change in response to external, State and global influences. Consequently, the institutions are having to adapt and in the process of doing so the traditional balance between learned society and qualifying association activities is now in…

Many authors have argued that word-learning constraints help guide a word-learner's hypotheses as to the meaning of a newly heard word. One such class of constraints derives from the observation that word-learners of all ages prefer to map novel labels to novel objects in situations of referential ambiguity. In this paper I use eye-tracking to…

Community colleges--institutions that serve disproportionate numbers of poor, working-class, first-generation, non-traditional, and minority students--are uniquely positioned to provide liberating educational experiences to a diverse spectrum of society. Cross (2000) aptly describes the current interest in cooperative and/or collaborative learning…

The project described in this article is less about the content area, computational cell biology, and more about the educational practice of the students and faculty involved. Over the course of the past four years, Dr. Raquell Holmes has worked to create curricular resources that support the integration of modeling methods in biology education.…
