Utilizing Peer Interactions To Promote Learning Through A Web-Based Peer Assessment System, Lan Li, Allen L. Steckelberg, Sribhagyam Srinivasan
Utilizing Peer Interactions To Promote Learning Through A Web-Based Peer Assessment System, Lan Li, Allen L. Steckelberg, Sribhagyam Srinivasan
Department of Teaching, Learning, and Teacher Education: Faculty Publications
Abstract: Peer assessment is an instructional strategy in which students evaluate each other’s performance for the purpose of improving learning. Despite its accepted use in higher education, researchers and educators have reported concerns such as students’ time on task, the impact of peer pressure on the accuracy of marking, and students’ lack of ability to make critical judgments about peers’ work. This study explored student perceptions of a web-based peer assessment system. Findings conclude that web-based peer assessment can be effective in minimizing peer pressure, reducing management workload, stimulating student interactions, and enhancing student understanding of marking criteria and critical …

Purpose: The ontogeny of mandibular control is important for understanding the general neurophysiologic development for speech and alimentary behaviors. Prior investigations suggest that mandibular control is organized distinctively across speech and nonspeech tasks in 15-month-olds and adults and that, with development, these extant forms of motor control primarily undergo refinement and rescaling. The present investigation was designed to evaluate whether these coordinative infrastructures for alimentary behaviors and speech are evident during the earliest period of their co-occurrence.
Method: Electromyographic (EMG) signals were obtained from the mandibular muscle groups of 15 typically developing 9-month-old children during sucking, chewing, and speech.
Results: …

Migraine-Associated Vestibulopathy, Julie A. Honaker, Ravi N. Samy
Department of Special Education and Communication Disorders: Faculty Publications
Purpose of review: In the past few years, otologists have been seeing an increasing number of patients with vestibular disorders due to migraine- associated vestibulopathy. This article reviews some of the latest developments in the understanding of this disease process, specifically its incidence, symptoms, diagnosis, and treatment.
Recent findings: Migraine-associated vestibular symptoms may include episodic true vertigo, movement-provoked dysequilibrium, imbalance/unsteadiness, and complaints of lightheadedness. The pathophysiology of migraine-associated vestibulopathy is not completely understood; however, both peripheral and central deficits have been observed. Although the International Headache Society classification does not include migraine-associated vestibulopathy as a subclassification of migraine, there is …
Pacifier Stiffness Alters The Dynamics Of The Suck Central Pattern Generator, Emily Zimmerman, Steven M. Barlow
Pacifier Stiffness Alters The Dynamics Of The Suck Central Pattern Generator, Emily Zimmerman, Steven M. Barlow
Department of Special Education and Communication Disorders: Faculty Publications
Variation in pacifier stiffness on non-nutritive suck (NNS) dynamics was examined among infants born prematurely with a history of respiratory distress syndrome. Three types of silicone pacifiers used in the NICU were tested for stiffness, revealing the Super Soothie™ nipple is 7 times stiffer than the Wee™ or Soothie™ pacifiers even though shape and displaced volume are identical. Suck dynamics among 20 preterm infants were subsequently sampled using the Soothie™ and Super Soothie™ pacifiers during follow-up at approximately 3 months of age. ANOVA revealed significant differences in NNS cycles/min, NNS amplitude, NNS cycles/burst, and NNS cycle periods as a function …

Department of Special Education and Communication Disorders: Faculty Publications
Aims and Objectives—Suck development is a challenging hurdle for preterm infants who endure an extensive oxygen history due to respiratory distress syndrome (RDS). The fine structure of the non-nutritive suck (NNS) was studied in preterm infants according to RDS severity.
Design and Methods—Recordings of NNS were completed cribside in the neonatal intensive care unit (NICU) in 55 preterm infants distributed among one healthy control group and two RDS infant groups. NNS pressure amplitude (cmH20) and within-burst suck cycle period (ms) were the dependent measures extracted from digitized records of pacifier nipple compression pressure.
Results and Conclusions—RDS preterm infants …

Department of Special Education and Communication Disorders: Faculty Publications
Sensory deprivation and motor restriction associated with extensive oxygen therapy may lead to poor oromotor control in preterm infants. Non-nutritive suck is one of the first complex oromotor behaviors infants perform. This study determined the spatiotemporal variability of non-nutritive suck (NNS) pressure trajectories in three preterm groups with differing oxygen histories—one control group with minimal or no O2 therapy, and two Respiratory Distress Syndrome (RDS) groups with either a mild/moderate (RDS1) or moderate/severe (RDS2) O2 history. The Non-nutritive Suck Spatiotemporal Index (NNS STI) quantifies spatial and temporal variability across kinematic trajectories, and was calculated from digital representations of …
Regional Volumetric Change Of The Tongue During Mastication In Pigs, Z. J. Liu, B. Yamamura, V. Shcherbatyy, Jordan R. Green
Regional Volumetric Change Of The Tongue During Mastication In Pigs, Z. J. Liu, B. Yamamura, V. Shcherbatyy, Jordan R. Green
Department of Special Education and Communication Disorders: Faculty Publications
Structure and movement of the tongue have been studied extensively, but little study has been carried on its 3D deformation and ensuing volumetric changes during various functions. The purpose of this study is to investigate the volumetric changes of a regional section of the tongue during feeding. Four 12-week-old Yucatan miniature pigs were used. During natural mastication and water drinking, the width, length, thickness and volumetric changes were measured using six implanted ultrasonic crystals, which circumscribed a wedge-shaped volume in the region of the tongue body. Jaw movements were videotaped and digitized. Signals from these two sources were synchronized to …

Department of Special Education and Communication Disorders: Faculty Publications
Objective—To characterize the integrity of non-nutritive suck (NNS) parameters among three groups of preterm infants ranging from normal to those with progressive degrees of respiratory distress syndrome (RDS).
Study Design—NNS compression waveforms were sampled from 55 infants in the neonatal intensive care unit using a silicone pacifier electronically instrumented for intraluminal pressure. Seven select NNS parameters were measured at two different sessions, and statistically analyzed using a General Linear Model Analysis of Covariance.
Results and Conclusions—Preterm infants with a more extensive history of RDS and oxygen therapy manifest significantly (p≤0.001) degraded performance on six of the seven NNS measures. This …

Short-Term Memory, Working Memory, And Executive Functioning In Preschoolers: Longitudinal Predictors Of Mathematical Achievement At Age 7 Years, Rebecca Bull, Kimberly Andrews Espy, Sandra A. Wiebe
Department of Educational Psychology: Faculty Publications
This study examined whether measures of short-term memory, working memory, and executive functioning in preschool children predict later proficiency in academic achievement at 7 years of age (third year of primary school). Children were tested in preschool (M age = 4 years, 6 months) on a battery of cognitive measures, and mathematics and reading outcomes (from standardized, norm-referenced school-based assessments) were taken on entry to primary school, and at the end of the first and third year of primary school. Growth curve analyses examined predictors of math and reading achievement across the duration of the study and revealed that …

Building Assignments That Teach, Mary-Ann Winkelmes
Professional and Organizational Development Network in Higher Education: Archives
We have come to take assignments for granted as a necessary part of undergraduate education, largely because they provide the basis for a student's grade. But assignments can accomplish much more. In addition to helping students learn course content, assignments can enable students to practice the most essential skills of a discipline. Further, assignments can offer an opportunity for students to become better evaluators of their own academic work.
Thoughtfully structured assignments offer teachers an opportunity to build students’ mastery of essential disciplinary skills alongside their content knowledge; to improve students’ ability to evaluate their own academic work; and even …

Beyond Writing: Integrative Learning And Teaching In First-Year Seminars, David H. Krause, Robert C. Lageaux
Professional and Organizational Development Network in Higher Education: Archives
Campuses across the country continue to establish first-year seminars that promise students integrative and transformative learning experiences necessary for the twenty-first century. This trend inevitably challenges faculty members to teach in ways that transcend or subvert both their disciplinary expertise and their familiar, comfortable ways of teaching. These challenges become especially visible in the design and evaluation of assignments. At Columbia College Chicago, for example, where the majority of students aspire to careers in the arts, media, and communication, teachers have been negotiating the place of writing in a required firstyear seminar in liberal learning. These negotiations play out differently …

Role-Play: An Often Misused Active Learning Strategy, Stephanie Nickerson
Professional and Organizational Development Network in Higher Education: Archives
Role-play is a special kind of case study, in which there is an explicit situation established with students playing specific roles, spontaneously saying and doing what they understand their “character” would, in that situation. Role-plays differ from other case studies in the immediacy of the experience. Students find themselves in the role-play. In a case study, they read about situations and characters. One of the reasons role-play can work so well is because of the power of placing oneself in another’s shoes. This provides opportunities for learning in both the affective domain, where emotions and values are involved, as well …

Teaching, Learning, And Spirituality In The College Classroom, Allison Pingree
Professional and Organizational Development Network in Higher Education: Archives
landscape is provoking a heightened focus on spirituality and religion in the academy. For example, UCLA’s Higher Education Research Institute (HERI), best known as the administrators of the CIRP Freshman Survey for over 40 years, is conducting a major research project, Spirituality in Higher Education (https://www.spirituality.ucla.edu), drawing data from over 112,000 students and 40,000 faculty at over 420 institutions. Defining spirituality in broad strokes (as the “interior” and “subjective” aspects of our lives, that which reflects the “values and ideals that we hold most dear,” gives us “meaning and purpose,” and invokes “inspiration, creativity, the mysterious, the sacred, …

Professional and Organizational Development Network in Higher Education: Archives
Academic departments from physics to philosophy to physical therapy face new demands for “assessment of student learning.” It’s hard to argue against the basic idea of assessment: when a department invests time and resources trying to nurture student learning, it should ask itself: Are they learning? Yet departments may also fear that assessment will require them to dumb-down their teaching; use standardized tests; teach alike; or compromise academic freedom. Every department wonders how it will find the time and resources for one more thing.
This essay suggests a simple, sustainable, and useful departmental assessment plan that capitalizes on what departments …

Collaboration Or Plagiarism? Explaining Collaborative-Based Assignments Clearly, Tuesday Cooper
Professional and Organizational Development Network in Higher Education: Archives
Much has been written about the use of collaborative learning as a pedagogical tool to enhance student learning. Collaborative learning, or group work as it is commonly known, can be defined as a structured process where students are required to work in groups to complete a common task or assignment for a particular course. It has been identified as one of the most effective ways for students to become actively engaged in classroom activities (Davis, 1993; McKeachie, 1999; Nilson, 1998).
Although there are many positive aspects of group work, there are negatives as well. One particular problem occurs when students …
Developing The Scholarship Of Teaching And Learning Using Faculty Learning Communities, Milton D. Cox
Developing The Scholarship Of Teaching And Learning Using Faculty Learning Communities, Milton D. Cox
Professional and Organizational Development Network in Higher Education: Archives
Faculty Learning Communities (FLCs) have proven successful in producing teaching projects, as evidenced by a survey of institutions with FLCs. It follows that these groups should provide ideal conditions for a subsequent development of those projects into peerreviewed publications and presentations, or the Scholarship of Teaching and Learning (SoTL). This essay offers faculty practical advice for producing such SoTL products based on what started as a teaching project in an FLC. My advice is based on work with FLCs for 28 years on my campus and others (Cox, 2003).

Full credit courses on teaching offered by academic departments for their own graduate students and postdocs have many advantages. Many students come to graduate school because they want teaching to be an important part of their future professional life. Most who are hired in academia will go to jobs where teaching is important. Indiana University’s Graduate School noted that 95% of its PhDs who landed tenure-track positions found those positions at liberal arts colleges, smaller comprehensive universities, and urban institutions. They noted that their teaching experience at Bloomington did not necessarily prepare them fully for these jobs.
