Research on teacher identities is both important and increasing. In this forum contribution I re-interpret assertions about
an African American science teacher’s identities in terms of Jonathon Turner’s (2002) constructs of role identity and sub-identity. I contest the notion of renegotiation of identities, suggesting that particular
role identities can be brought to the foreground and then backgrounded depending on the situation and the need to confirm
a sub-identity. Finally, I recommend the inclusion of teachers’ voices in identity research through greater use of co-authoring
roles for teachers.

This design-based research study is aimed at two goals: (1) developing a feasible case-based instructional model that could
enhance college students’ ill-structured problem solving abilities, while (2) implementing the model to improve teacher education
students’ real-world problem solving abilities to deal with dilemmas faced by practicing teachers in elementary classrooms.
To achieve these goals, an online case-based learning environment for classroom management problem solving (CBL-CMPS) was
developed based on Jonassen’s (in: Reigeluth (ed.) Instructional-Design Theories and Models: A New Paradigm of Instructional Theory, 1999) constructivist learning environment model and the general process of ill-structured problem solving (1997). Two successive
studies, in which the effectiveness of the CBL-CMPS was tested while the CBL-CMPS was revised, showed that the individual
components of the CBL-CMPS promoted ill-structured problem solving abilities respectively, and that the CBL-CMPS as a whole
learning environment was effective to a degree for the transfer of learning in ill-structured problem solving. The potential,
challenge, and implications of the CBL-CMPS are discussed.

This paper reports a part of a study on the construction of mathematical meanings in terms of development of semiotic systems
(gestures, speech in oral and written form, drawings) in a Vygotskian framework, where artefacts are used as tools of semiotic
mediation. It describes a teaching experiment on perspective drawing at primary school (fourth to fifth grade classes), starting
from a concrete experience with a Dürer’s glass to the interpretation of a new artefact. We analyse the long term process
of appropriation of the mathematical model of perspective drawing (visual pyramid) through the development of gestures, speech
and drawings under the teacher’s guidance.

The Impact of an Engineering Design Curriculum on Science Reasoning in an Urban Setting 总被引:2,自引:2,他引:0

This study examines the use of engineering design to facilitate science reasoning in high-needs, urban classrooms. The Design
for Science unit utilizes scaffolds consistent with reform science instruction to assist students in constructing a design
solution to satisfy a need from their everyday lives. This provides a meaningful context in which students could reason scientifically.
Eighth grade students from two urban schools participated in the unit. Both schools contained large percentages of racial/ethnic
minority and economically disadvantaged students. Students demonstrated statistically significant improvement on a paper-and-pencil,
multiple-choice pre and post assessment. The results compare favorably with both a high-quality inquiry science unit and a
traditional textbook curriculum. Implications for the use of design-based curricula as a viable alternative for teaching science
reasoning in high-needs, urban settings are discussed.

With our conceptualization of Harré and van Langenhove’s (1999) positioning theory, we draw attention to immanent experience and read transcendent discursive practices through the moment
of interaction. We use a series of spatial images as metaphors to analyze the way positioning is conceptualized in current
mathematics education literature and the way it may be alternatively conceptualized. This leads us to claim that changing
the way mathematics is talked about and changing the stories (or myths) told about mathematics is necessary for efforts to
change the way mathematics is done and the way it is taught.

This paper draws on my personal experiences with coteaching and my participation in the research described by Wassell and
LaVan (2009). It examines the role of coteaching in the development of structures that afforded opportunities for shared reflection and
shared responsibility between stakeholders in the classroom. It also describes how the schema and practices developed through
coteaching and cogenerative dialogue helped mediate the transition between my preservice and inservice teaching experiences.

The doctoral advisor is said to be one of the most important persons—if not the single most critical person—with whom doctoral students will develop a relationship during their doctoral degree programs
(Baird 1995). However, we have limited knowledge regarding how doctoral advisors see their roles and responsibilities as advisors. Therefore,
through in-depth interviews, we explored the perceptions of 25 exemplary doctoral advisors, who have graduated a large number
of doctoral students, about their roles and responsibilities as advisors. We conclude this article with implications for doctoral
education.

This is a report of one case of a design and development research study that aimed to validate an overlay instructional design
model incorporating the theory of multiple intelligences into instructional systems design. After design and expert review
model validation, The Multiple Intelligence (MI) Design Model, used with an Instructional Systems Design (ISD) Model, was
tested for use by four practicing instructional designers. Instruction developed for learners using this model was then evaluated
measuring post-test and attitudinal scores with 102 participants. This report also provides a reflection on the lessons learned
in conducting design and development research on model validation. The procedures and findings have implications for the processes
involved in instructional design model validation through designer use and program implementation.

Instruction on problem solving in particular domains typically relies on explanations from experts about their strategies.
However, research indicates that such self-reports often are incomplete or inaccurate (e.g., Chao & Salvendy, 1994; Cooke & Breedin, 1994). This article evaluates research on experts’ cognition, the accuracy of experts’ self-reports, and the efficacy of instruction
based on experts’ self-reports. Analysis of this evidence indicates that experts’ free recall of strategies introduces errors
and omissions into instructional materials that hinder student success. In contrast, when experts engage in structured knowledge
elicitation techniques (e.g., cognitive task analysis), the resultant instruction is more effective. Based on these findings,
the article provides a theoretical explanation of experts’ self-report errors and discusses implications for the continued
improvement of instructional design processes.
