Service-Learning's Impact on Developmental Reading/Writing and Student Life Skills Courses

Designed to investigate the impact of service-learning on developmental-level students' success and retention, this study reports the results of pre-and postcourse surveys with service-learning and nonservice-learning sections of developmental courses at Miami-Dade College. Knowledge gained, course pass rates, and both in-class and semester-to-semester retention are reported.     

Early childhood education on‐line: Challenges and rewards

Abstract

This paper describes our collaborative experiences in the process of developing, designing, and facilitating an online graduate level course in early childhood education. Data collection strategies included: pre/post course questionnaires, informal conversations with students, and university course evaluations. This information described the experiences of novice computer users as they engaged in their content area (early childhood education) and also developed expertise in navigating the computer environment.     

Collaborative teaming and critical reflection: A model for practice in preservice programs and general education settings

Abstract

Inclusion settings for young children with mild to moderate educational needs are becoming the norm. Development of collaborative intervention teams has become essential to effective inclusion. Models of collaborative team development have described multiple aspects of team developmental stages (Tuckman & Jensen, 1977; Lowe & Herranen, 1982). What may be missing in these professional models is the understanding of intrinsic personal qualities that may support or inhibit team development. The model proposed in this reflection advocates a combination of professional and personal commitment models of team development. The authors also explore the benefits of critical reflection about team processes and the value of developing collaborative preservice preparation programs and collaborative intervention models at the preschool and primary levels.     

The Quest for Gender Equity in America's Schools: From Preschool and Beyond

"Nothing can be more absurd than the practice which prevails in our country of men and women not following the same pursuits with all their strengths and with one mind, for thus the state instead of being whole, is reduced to half.” Plato, 24 B. C.     

A case study: the evolution of a ��facilitator model�� liaison program in an academic medical library

Question:

What type of liaison program would best utilize both librarians and other library staff to effectively promote library services and resources to campus departments?

Setting:

The case is an academic medical center library serving a large, diverse campus.

Methods:

The library implemented a “facilitator model” program to provide personalized service to targeted clients that allowed for maximum staff participation with limited subject familiarity. To determine success, details of liaison-contact interactions and results of liaison and department surveys were reviewed.

Results:

Liaisons successfully recorded 595 interactions during the program''s first 10 months of existence. A significant majority of departmental contact persons (82.5%) indicated they were aware of the liaison program, and 75% indicated they preferred email communication.

Conclusion:

The “facilitator model” provides a well-defined structure for assigning liaisons to departments or groups; however, training is essential to ensure that liaisons are able to communicate effectively with their clients.     

Time to rethink the role of the library in educating doctors: driving information literacy in the clinical environment

Question:

Can information literacy (IL) be embedded into the curriculum and clinical environment to facilitate patient care and lifelong learning?

Setting:

The Australian School of Advanced Medicine (ASAM) provides competence-based programs incorporating patient-centred care and lifelong learning. ASAM librarians use outcomes-based educational theory to embed and assess IL into ASAM''s educational and clinical environments.

Methods:

A competence-based IL program was developed where learning outcomes were linked to current patients and assessed with checklists. Weekly case presentations included clinicians'' literature search strategies, results, and conclusions. Librarians provided support to clinicians'' literature searches and assessed their presentations using a checklist.

Main Results:

Outcome data showed clinicians'' searching skills improved over time; however, advanced MEDLINE searching remained challenging for some. Recommendations are provided.

Conclusion:

IL learning that takes place in context using measurable outcomes is more meaningful, is enduring, and likely contributes to patient care. Competence-based assessment drives learning in this environment.     

Experimental validation of numerical study on thermoelectric-based heating in an integrated centrifugal microfluidic platform for polymerase chain reaction amplification

A comprehensive study involving numerical analysis and experimental validation of temperature transients within a microchamber was performed for thermocycling operation in an integrated centrifugal microfluidic platform for polymerase chain reaction (PCR) amplification. Controlled heating and cooling of biological samples are essential processes in many sample preparation and detection steps for micro-total analysis systems. Specifically, the PCR process relies on highly controllable and uniform heating of nucleic acid samples for successful and efficient amplification. In these miniaturized systems, the heating process is often performed more rapidly, making the temperature control more difficult, and adding complexity to the integrated hardware system. To gain further insight into the complex temperature profiles within the PCR microchamber, numerical simulations using computational fluid dynamics and computational heat transfer were performed. The designed integrated centrifugal microfluidics platform utilizes thermoelectrics for ice-valving and thermocycling for PCR amplification. Embedded micro-thermocouples were used to record the static and dynamic thermal responses in the experiments. The data collected was subsequently used for computational validation of the numerical predictions for the system response during thermocycling, and these simulations were found to be in agreement with the experimental data to within ∼97%. When thermal contact resistance values were incorporated in the simulations, the numerical predictions were found to be in agreement with the experimental data to within ∼99.9%. This in-depth numerical modeling and experimental validation of a complex single-sided heating platform provide insights into hardware and system design for multi-layered polymer microfluidic systems. In addition, the biological capability along with the practical feasibility of the integrated system is demonstrated by successfully performing PCR amplification of a Group B Streptococcus gene.     

Concurrent validity and test–retest reliability of a global positioning system (GPS) and timing gates to assess sprint performance variables

Abstract

There has been no previous investigation of the concurrent validity and reliability of the current 5 Hz global positioning system (GPS) to assess sprinting speed or the reliability of integrated GPS–accelerometer technology. In the present study, we wished to determine: (1) the concurrent validity and reliability of a GPS and timing gates to measure sprinting speed or distance, and (2) the reliability of proper accelerations recorded via GPS–accelerometer integration. Nineteen elite youth rugby league players performed two over-ground sprints and were simultaneously assessed using GPS and timing gates. The GPS measurements systematically underestimated both distance and timing gate speed. The GPS measurements were reliable for all variables of distance and speed (coefficient of variation [CV] = 1.62% to 2.3%), particularly peak speed (95% limits of agreement [LOA] = 0.00 ± 0.8 km · h^?1; CV = 0.78%). Timing gates were more reliable (CV = 1% to 1.54%) than equivalent GPS measurements. Accelerometer measurements were least reliable (CV = 4.69% to 5.16%), particularly for the frequency of proper accelerations (95% LOA = 1.00 ± 5.43; CV = 14.12%). Timing gates and GPS were found to reliably assess speed and distance, although the validity of the GPS remains questionable. The error found in accelerometer measurements indicates the limits of this device for detecting changes in performance.
