Analytic Frameworks for Assessing Dialogic Argumentation in Online Learning Environments

Over the last decade, researchers have developed sophisticated online learning environments to support students engaging in dialogic argumentation. This review examines five categories of analytic frameworks for measuring participant interactions within these environments focusing on (1) formal argumentation structure, (2) conceptual quality, (3) nature and function of contributions within the dialogue, (4) epistemic nature of reasoning, and (5) argumentation sequences and interaction patterns. Ultimately, the review underscores the diversity of theoretical perspectives represented within this research, the nature of dialogic interaction within these environments, the importance of clearly specifying theoretical and environmental commitments throughout the process of developing or adopting an analytic framework, and the role of analytic frameworks in the future development of online learning environments for argumentation.

Weighing Fog: Modeling on Day 1 of Differential Equations

Abstract

The first day of many mathematics classes is filled with the formalities of the syllabus and a lecture introduction to the course content. Here, an alternative is presented where modeling is placed as the centerpiece to orient students to the work of differential equations; namely, to capture as beautifully and compactly as possible through the process of inquiry, conjecture, and experimentation, the deep and interesting aspects of modeling the physical world. A demonstration of the sublimation of dry ice in water serves as the nucleus of the lesson.     

Negotiating the transition to middle school: the role of self-regulatory processes

The present research examined the role of maladaptive self-regulatory beliefs as vulnerability factors for academic and emotional difficulties during the transition to middle school. A short-term longitudinal design was employed to follow two groups of early adolescents: 187 adolescents who experienced a school transition between the fifth and sixth grades, and 142 adolescents who did not experience a school transition between the fifth and sixth grades. Adolescents completed measures of perceptions of academic control and importance of academic success, experience of chronic academic strain, daily school hassles, and depressive symptoms. Teachers reported on students' academic engagement, including levels of helpless behavior, effort, and academic performance. Consistent with the proposed model of self-regulation, maladaptive self-regulatory beliefs (i.e., decreased perceptions of academic control and importance) predicted individual differences in perceived school-related stress and depressive symptoms over the course of the middle school transition, but were not associated with academic and emotional difficulties in adolescents who remained in a stable school environment. Moreover, a self-regulatory sequence was identified proceeding from maladaptive self-regulatory beliefs, to academic disengagement, to enhanced perceptions of school-related stress, to depressive symptoms. This study bridges prior theory and research concerning the psychological impact of normative developmental transitions, the developmental context of depression, and the associations among self-regulatory beliefs, achievement-related behavior, and emotional experience.     

Evidence for confounding in computer-based instruction studies: Analyzing the meta-analyses

A thirty percent sample of the computer-based instruction (CBI) studies meta-analyzed by Kulik et al was examined for evidence of confounding. The purpose of the analysis was to explore the validity of competing claims about the contribution of the computer to measured achievement gains found in CBI studies. Some of these claims propose that CBI effects are overestimated and others argue that CBI effects are underestimated. The result of the analysis strongly suggests that achievement gains found in these CBI studies are overestimated and are actually due to the uncontrolled but robust instructional methods embedded in CBI treatments. It is argued that these methods may be delivered by other media with achievement gains comparable to those reported for computers. Construct validity cautions are offered for those who wish to use meta-analytic results as evidence for implementing CBI in schools and for the design of future CBI research.     

Test Takers and the Validity of Score Interpretations

This article argues that test takers are as integral to determining validity of test scores as defining target content and conditioning inferences on test use. A principled sustained attention to how students interact with assessment opportunities is essential, as is a principled sustained evaluation of evidence confirming the validity or calling into question the inferences for individual students. Three innovative assessment systems are highlighted to illustrate where and how the developers might handle diverse test taker needs and learning characteristics. ONPAR measures challenging content using multisemiotic methods and novel item types, designing items to handle multiple profiles so they are accessible for most students. Dynamic Learning Maps has built an innovative network of learning maps, and multiple pathways designed to model how diverse students acquire knowledge. To support their assessments, the National Center and State Collaborative has built an exemplary web of educator resources such as content modules and guides in order to support differentiated learning.     

The Place of Philosophy in the Training of Teachers: Peters revisited

Abstract

In 1964, Richard Peters examined the place of philosophy in the training of teachers. He considered three things: Why should philosophy of education be included in the training of teachers; What portion of philosophy of education should be included; How should philosophy be taught to those training to be teachers. This article explores the context of the time when Peters set out his views, describes philosophy of education at the London Institute of Education at one period in Peters’ time there, and then discusses the current state of philosophy of education, using New Zealand as an example of opportunities and challenges. Finally, asking whether Peters was nearly right about the place of philosophy in the training of teachers, it is concluded that he was right about its importance but got it wrong about his conception of philosophy.     

DEVELOPING AND EVALUATING AN INTERDISCIPLINARY CLINICAL TEAM TRAINING PROGRAM: LESSONS TAUGHT AND LESSONS LEARNED

The training of clinicians in working together as an interdisciplinary team has received growing support in geriatrics. Most teamwork training programs have focused on group process and development as the core competencies of team practice necessary to improve levels of team functioning. The experience of the Rhode Island Geriatric Education Center (RIGEC) in developing and implementing an ongoing teamwork training program, including the training of several geriatric teams from a variety of health care settings, suggests that additional objectives should include the empowerment of teams for advocacy in rapidly changing health care settings increasingly shaped by economic forces. The lessons learned by RIGEC for the development and implementation of teamwork training include the importance of defining team membership, dealing with the shifting shoals of the health care system, understanding individuals and systems under stress, and redefining the objectives of teamwork training.     

Autonomy: The importance of a scientific theory in education reform

The six national goals established by the National Governors' Association for education reform in the 1990s were conceived by people who had the power to decide what outcomes they wanted based on their own values and priorities. Although it is impossible to avoid questions of values, it is necessary in defining goals for education to consider scientific, explanatory theories about how human beings acquire knowledge and moral values. Jean Piaget's conceptualization of autonomy, in his unusual sense of the term, provides an overall aim for the development of individuals as well as of society, both in the intellectual and the moral realms. Autonomy as the aim of education is based on constructivism, a scientific theory, and would obviate the outdated conceptualization and contradictions among the six national goals.
