Proctored Versus Unproctored Online Exams: Studying the Impact of Exam Environment on Student Performance

Increasing numbers of universities are offering courses in online and hybrid formats. One challenge in online assessment is the maintenance of academic integrity. We present a thorough statistical analysis to uncover differences in student performance when online exams are administered in a proctored environment (i.e., in class) versus an unproctored environment (i.e., offsite). Controlling for student grade point average (GPA), no significant differences in mean overall course performance or exam performance between the two groups were found, nor were there any differences in the mean vectors of individual exam scores. The study reveals that the group taking online exams in the unproctored environment has significantly more variation in their performance results. In examining potential causes of the greater variation, analyses were performed to assess whether an increased level of possible cheating behavior could be observed from performance results for students in the unproctored section. No evidence of cheating behavior was found.     

Images of the Body from Popular Culture: Engaging Adolescent Girls in Critical Inquiry

The purpose of this paper is to highlight how I use images from teen magazines to engage girls in critical inquiry about the body. This process is about co-constructing bodily knowledge and reflecting critically on this knowledge. The analysis is broken into three main parts: (a) tapping girls' interests; (b) helping girls name how they experience their bodies; and (c) using images to critique dominant stories of the body. Within each of these sections, I will foreground the process by looking at the curricular tasks as well as the verbal engagement through which the girls and I negotiated the tasks together. The data are used to illustrate the pedagogical possibilities of engaging girls in critical inquiry on body. I conclude the paper by discussing the pedagogical possibilities for studying the body with adolescent girls that emerged and reflect critically on the struggles involved in the process of engaging girls in critical inquiry.     

Using collaborative two‐stage examinations to address test anxiety in a large enrollment gateway course

Large enrollment foundational courses are perceived as “high stakes” because of their potential to act as barriers for progression to the next course or admittance to a program. The nature of gateway courses makes them ideal settings to explore the relationship between anxiety, pedagogical interventions, and student performance. Here, two‐stage collaborative examinations were implemented to improve test‐taking skills and address widespread test anxiety in an introductory human anatomy course. Test anxiety data were collected (using the Motivated Strategies for Learning Questionnaire) before the first examination and last examination. Most students experienced decreased test anxiety over the course of the semester; however, some students may have experienced performance limiting conditions due to test anxiety at the end of the semester based on academic ability in the course (in “C” students when compared to “A” students: P < 0.00006 and “B” students: P < 0.05), overall academic ability (in academically weaker students: P < 0.025), and demographic factors (in women: P < 0.025). The strongest performances on examinations were primarily observed in already academically strong students (mean individual performance: P < 0.000, mean group performance: P < 0.000). Furthermore, changes in test anxiety were not significantly associated with the group portion of the examinations. Patterns of changes in test anxiety over the course of the semester underscore a complex interaction between test anxiety, student background, and student performance. Results suggest that pathways for test anxiety in “high stakes” courses may be separate from the mechanisms responsible for the benefits of collaborative testing.

Assessment of physical activity with the Computer Science and Applications, Inc., accelerometer: laboratory versus field validation

Our purpose was to compare the validity of the Computer Science and Applications, (CSA) Inc., accelerometer in laboratory and field settings and establish CSA count ranges for light, moderate, and vigorous physical activity. Validity was determined in 60 adults during treadmill exercise, using oxygen consumption (VO2) as the criterion measure, while 30 adults walked and jogged outdoors on a 400-m track. The relationship between CSA counts and VO2 was linear (R2 = .89 SEE = 3.72 ml.kg-1.min-1), as was the relationship between velocity and counts in the field (R2 = .89, SEE = 0.89 mi.hr-1). However, significant differences were found (p < .05) between laboratory and field measures of CSA counts for light and vigorous intensity. We conclude that the CSA can be used to quantify walking and jogging outdoors on level ground; however, laboratory equations may not be appropriate for use in field settings, particularly for light and vigorous activity.     

The footprint and the stepping foot: archival records, evidence, and time

This paper provides an analysis of the archival concepts of “record” and “evidence” as socio-cultural constructs arising out of a particular view of time. Archival records are usually characterized as having certain relationships to evidence in its temporal aspects—specifically, the requirement for a temporal disconnect between creation and use. This disconnect also necessitates a break between knowledge and the knower in which the record must be externalized and set aside from its creator in order to have “recordness”. This paper explores how Western concepts of time impact concepts of records and archival evidences and proposes an alternative framing. Since records have such power in our lives and societies, practitioners must begin to work with an expanded concept of record and sensitivity to differing time frames and worldviews. The paper proposes a new definition of “record” as an intentional, stable, semantic structure, which is used to identify three broad categories of record types, based on event-orientation or object-orientation, that are flexible enough to account for differing cultural and spiritual understandings of time.     

Composing new understandings of sustainability in the Anthropocene

The relationship between sustainability and the Anthropocene takes on new meaning in a time of unprecedented human impact on Earth systems. This relationship is at times contested and not well researched but critical in considering how we will respond to environmental challenges of today and the future. Elaborating on the need for new perspectives and nuanced understandings of sustainability, the contributors to this volume draw on posthumanist and “new” feminist materialist methodologies and theoretical lenses to engage readers in ways, which often contrast with prevailing thinking and research. From the cosmopolitics of place in urban Berlin to the watery space of urban wetlands they share research and rich narratives, which illustrate how sustainability is theorized and enacted across a range of diverse educational contexts. Moving beyond the rhetoric of sustainability, the authors invite us to explore innovative ways to engage with new concepts and emerging tensions that are now influencing the fields of education and sustainability.     

Thyroid hormone levels and psychological symptoms in sexually abused adolescent girls

OBJECTIVE: To explore the relationships between psychological symptoms and thyroid hormone levels in adolescent girls who had experienced the traumatic stress of sexual abuse. METHOD: The study design was cross-sectional/correlational. Subjects (N=22; age range=12-18 years) had their blood drawn, and they completed 2 psychological tests (depression and general distress/posttraumatic stress disorder [PTSD]). A pediatrician completed a sexual abuse questionnaire after reviewing law enforcement and Child Protective Services reports and conducting forensic interviews and medical examinations. RESULTS: Girls' average free T4, total T4, free T3, total T3, and TSH levels were within age-specific laboratory reference range limits, as were most individual concentrations. The strongest correlations (p<.05) were between free T3 and PTSD total score (-.50), PTSD-avoidance/numbing (-.49), and general distress (-.48); and between total T3 and depression (-.46), general distress (-.45), and PTSD-arousal (-.44). CONCLUSIONS: Our findings support one of the two contemporary models of the relationships between thyroid hormones (i.e., free and total T3) and psychological symptoms (i.e., depression, general distress, and PTSD)--one of "shutting down" (vs. "activation") in the face of trauma.     

ELDERCARE IN THE 1990s: CHALLENGES AND SUPPORTS FOR EDUCATING FAMILIES

The purpose of this article is to summarize the recent literature on caregiving in order to identify viable ways to educate families to care for elderly relatives in the home environment. The demands and stresses currently associated with providing home care to older members are discussed, followed by an overview of support services that represent promising and workable approaches in enhancing families’ home‐caregiving capacities. With few exceptions, this paper is based on caregiving research published in the past five years.     

USING LISTENING JOURNALS IN MATH METHODS

The purpose of this teacher action research was twofold: to learn more about preservice teachers' preconceived notions related to listening and to investigate how a listening journal assignment impacted preservice teachers' views of listening as an important aspect of discourse. The participants were enrolled in a mathematics methods course for PreK–3 (early childhood) majors during their last semester of coursework prior to student teaching. Data in the form of final reflections from participants' listening journals and researchers' field notes were analyzed. Findings suggest that the preservice teachers entered the course without truly considering listening as an important component of teaching methods related to facilitating classroom discourse. The listening journal assignment helped them begin to think more deeply about listening and the different definitions and modes of listening; however, at the end of the semester, many still wrote about their own personal journeys with listening and not about the role of listening as a key element in promoting classroom discourse and learning.
