Student Behavior and Epistemological Framing: Examples from Collaborative Active-Learning Activities in Physics

The concept of framing from anthropology and sociolinguistics is useful for understanding student reasoning. For example, a student may frame a learning activity as an opportunity for sensemaking or as an assignment to fill out a worksheet. The student's framing affects what she notices, what knowledge she accesses, and how she thinks to act. We find evidence of framing in easily observed features of students' collaborative behavior. We apply this observational methodology to explore dynamics among behavior, framing, and the conceptual substance of student reasoning in the context of collaborative active-learning activities in an introductory university physics course. We find evidence that certain student behaviors indicate and support a relatively sophisticated epistemological framing of these activities, one in which students discuss the substance of the ideas at hand.     

Timely Completion of Class Requirements: Effects of Student and Faculty Gender

Male and female students have displayed different reactions to the gender of their faculty. This research was designed to explore whether biases exist early in the school term. Students unfavorable attitudes toward instructors were measured by the extent to which they delayed completing a course requirement: participation in a subject pool. Students scheduled a date upon which to participate in a research study. Discrepancies between their scheduled and their actual participation dates reveal that male students delayed their requirement (a) more when their instructors were female than when they were male, and (b) more than female students when the instructors were female. Supporting data suggest that the delayed completion time reflects lower evaluations of female faculty. Discussion focuses on implications in academic settings.     

A Multivariate Analysis of Selected Class Characteristic and Student Rating of Instruction

This study examined the relationship between selected class characteristics and student ratings of instructors. A large number of classes (N = 1247)and students (over 33,000) a t a large Midwestern University provided the data for this study. The results indicated that the class characteristics that had the strongest influence on the results of instructor ratings were the grades expected by students and the percentage of students in the class taking the course as an elective.     

Argument as Inquiry in a Postmodern Context

Argumentation is a form of communication, rather than an application of(formal) logic, and is used in communicative activity as a means forinquiry, although it is more typically thought of as bringing inquiry toclosure. Thus interpretation is an intrinsic and crucial aspect ofconversational (interactive) argumentation. In order to further thisunderstanding of argumentative activity, I propose a procedure forinterpretation that draws upon hermeneutic phenomenology. In response tocriticisms by argumentation theorists (and others) who understand thistradition as oriented to psychological, perceptual, or textual objects, Iargue that hermeneutic phenomenology supports methods for analysis ofpublic communicative activity. The resulting conception of thick argumentation responds to contemporary (postmodern) claims that argumentation valorizes univocity, stasis, and certainty at the expense ofthe pluralism, fluctuation, and range of epistemic results thatcharacterize discourse in the public sphere.     

Student Changes, Program Influences, and Adult Development in One Program of Counselor Training: An Exploratory Inductive Inquiry

This qualitative study explored how students in 1 program changed as a result of their professional preparation experience. We interviewed 15 counseling students via one-to-one interviews and a focus group. Students were asked how they had changed and what had influenced those changes in their educational experience. Responses were clustered with the assistance of a text analysis computer program. Three broad change themes were named (1) increased reflexivity, (2) increased autonomy, and (3) capacity for dialogue. Four program influences were also identified. They are providing students with (1) experiences in social construction of knowledge, (2) experiential learning, (3) opportunities for independent thinking, and (4) a supportive environment. Connections to adult-development themes and specific instructional strategies that are suggested by the data are named.     

Supporting Whole-class Collaborative Inquiry in a Secondary Mathematics Classroom

Recent mathematics education reform efforts call for the instantiation of mathematics classroom environments where students have opportunities to reason and construct their understandings as part of a community of learners. Despite some successes, traditional models of instruction still dominate the educational landscape. This limited success can be attributed, in part, to an underdeveloped understanding of the roles teachers must enact to successfully organize and participate in collaborative classroom practices. Toward this end, an in-depth longitudinal case study of a collaborative high school mathematics classroom was undertaken guided by the following two questions: What roles do these collaborative practices require of teacher and students? How does the community's capacity to engage in collaborative practices develop over time? The analyses produced two conceptual models: one of the teacher's role, along with specific instructional strategies the teacher used to organize a collaborative learning environment, and another of the process by which the class's capacity to participate in collaborative inquiry practices developed over time.     

Student Attitudinal Changes in a Counseling Ethics Course

The purpose of this study was to investigate ethical attitude changes in counselors in training related to specific topics during a 16-week, two-credit counseling ethics course. This study indicated that significant attitudinal changes occurred related to professional ethics and self-awareness, dual relationships, impairment, and multiculturalism.     

Effects of Crowding in a Student Environment1

Responses to crowding were examined in two student dormitories (Dorm A and Dorm B). Dorm B had more rooms per floor, smaller sized rooms, and a general layout which seemed conducive to a higher level of social stimulation. Students living in Dorm B reported being less involved with their roommates, being in a worse mmod, and experiencing more crowding. The role of crowding in mediating the relationship between type of dormitory as an independent variable and mood and interpersonal relationship as dependent variables was discussed.     

Argumentative Polylogues in a Dialectical Framework: A Methodological Inquiry

In this paper, we closely examine the various ways in which a multi-party argumentative discussion—argumentative polylogue—can be analyzed in a dialectical framework. Our chief concern is that while multi-party and multi-position discussions are characteristic of a large class of argumentative activities, dialectical approaches would analyze and evaluate them in terms of dyadic exchanges between two parties: pro and con. Using as an example an academic committee arguing about the researcher of the year as well as other cases from argumentation literature, we scrutinize the advantages and pitfalls of applying a dialectical framework to polylogue analysis and evaluation. We recognize two basic dialectical methods: interpreting polylogues as exchanges between two main camps and splitting polylogues into a multitude of dual encounters. On the basis of this critical inquiry, we lay out an argument expressing the need for an improved polylogical model and propose its basic elements.     

Transitions between Modes of Inquiry in a Rule Discovery Task

Scientists obtain their knowledge about the world through one of two major modes of inquiry—observation of naturally occurring phenomena and active experimentation. Both modes of inquiry have been extensively researched in studies of hypothesis testing behaviour and scientific inquiry, the first in studies employing the reception paradigm, the second in studies employing the selection/generation paradigm. The prevalence of both paradigms and their correspondence to well-established modes of scientific inquiry led to the hypothesis that subjects, if allowed, would employ both modes of inquiry. The variables affecting the choice of one mode rather than the other and the transitions between the two modes were expected to shed new light on the process of scientific inquiry. To test this hypothesis, 27 adults and 27 eighth-graders were set three rule-discovery problems, in a computer environment that allowed free transitions between item reception and generation. Item generation was significantly more prevalent in the adult sample, but almost all the adults and approximately half the children employed both modes of inquiry in at least one problem. When both modes of inquiry were employed, the reception mode tended to precede the generation mode. An inverse relationship was observed between item generation and the proportion of positive instances supplied by the environment. Individual inquiry styles were evident in both age groups. These results call attention to the need for a theory incorporating both modes of inquiry as integral components of the inquiry process. They also demonstrate the utility of empirical investigations that let subjects freely choose which mode to employ at any point of the inquiry process.     

Inquiry method effects on performance in a simulated business environment

The dialectical inquiry (DI) and devil's advocate (DA) techniques have been offered as two options for providing information to the decision maker. Several prior studies have not resolved the relative advantages between these two “inquiry methods.” This paper reports two studies that involve a business simulation task and an inquiry method manipulation. In the first study with student subjects as decision makers, the DA advice was more useful than the DI advice in a situation wherein plant and work force expansions were frequent. In the second study with experienced managers, very few expansion decisions were made, and the nature of DA or DI advice made no significant difference. Instead, a recommendation to engage in a high profit margin, low volume strategy proved useful in some conditions.     

The Student as a Physical Being

A pretty freshman, feeling “in a bind” because of academic demands, broke out with hives on her buttocks as she sat at her desk studying; a few days later she was hospitalized with mononucleosis. … Shortly before Christmas vacation a group of coeds noted that the occurrence of menstrual discomforts had suddenly increased in their living units. … A junior, who was experiencing difficulties with her roommate and also her fiancé, developed a constant craving for food and became anxious when her food binges started getting out of hand. …     

A Study of Posttraumatic Stress in a Student Population

The authors examined the incidence of posttraumatic stress (PTS), with respect to levels of exposure to traumatic events, in a British student population. Respondents (N = 700) completed a standard questionnaire booklet that contained a posttraumatic stress disorder interview. The questionnaire collected personal demographic information and was used by researchers to ascertain whether respondents had experienced a traumatic event. Consistent with previous American studies, PTS was found to be relatively common; 23.3% of the sample showed either current or past PTS. Female participants had a significantly higher incidence of PTS than did male participants, although the latter were more likely to report having experienced a traumatic event. The experience of trauma was significantly associated with the likelihood of PTS. The authors discuss implications of their results in terms of long-term consequences of unresolved trauma.
