Research suggests that spatial ability may predict success in complex disciplines including anatomy, where mastery requires a firm understanding of the intricate relationships occurring along the course of veins, arteries, and nerves, as they traverse through and around bones, muscles, and organs. Debate exists on the malleability of spatial ability, and some suggest that spatial ability can be enhanced through training. It is hypothesized that spatial ability can be trained in low-performing individuals through visual guidance. To address this, training was completed through a visual guidance protocol. This protocol was based on eye-movement patterns of high-performing individuals, collected via eye-tracking as they completed an Electronic Mental Rotations Test (EMRT). The effects of guidance were evaluated using 33 individuals with low mental rotation ability, in a counterbalanced crossover design. Individuals were placed in one of two treatment groups (late or early guidance) and completed both a guided, and an unguided EMRT. A third group (no guidance/control) completed two unguided EMRTs. All groups demonstrated an increase in EMRT scores on their second test (P < 0.001); however, an interaction was observed between treatment and test iteration (P = 0.024). The effect of guidance on scores was contingent on when the guidance was applied. When guidance was applied early, scores were significantly greater than expected (P = 0.028). These findings suggest that by guiding individuals with low mental rotation ability “where” to look early in training, better search approaches may be adopted, yielding improvements in spatial reasoning scores. It is proposed that visual guidance may be applied in spatial fields, such as STEMM (science, technology, engineering, mathematics and medicine), surgery, and anatomy to improve student's interpretation of visual content.

How We Used to Build the Future: 30 Years of Collection Development Trends     

Betsy Appleton  Justin Clarke  Laurie Kaplan  Dani Roach  Rebecca Kemp Goldfinger 《期刊图书馆员》2016,70(1-4):198-203

This session highlighted trends in continuing resource collections and collection management throughout the 30-year period from 1985 through 2015. Electronic resources became available in the 1990s and grew in prevalence from the 2000s through the present, changing the make-up of library collections and also how libraries measure collections and collection usage. Two librarians and two vendors shared their perspectives on these changes in collection development, describing how library collections now contain a combination of older formats and older ways of collecting data, and new, electronic content and automated ways of collecting and disseminating data about collections.  相似文献   

Successful Concurrent Programs: An EXCELerate Program in Oklahoma     

Juanita Gamez Vargas  Rick Roach  Kevin M. David 《Community College Journal of Research & Practice》2014,38(2-3):166-173

The article presents the implementation and findings of a successful collaborative effort with the Oklahoma State Regents for Higher Education (OSRHE), Tulsa Community College (TCC), and two local public school districts, Tulsa Public Schools (TPS) and Union Public Schools (UPS). Known as EXCELerate, it's a five-semester dual enrollment pilot program that received state policy exceptions for juniors and seniors to enroll in dual enrollment courses and supportive resources from the participating agencies. Whereas the traditional dual enrollment student is White and college-going, the program's intent was to increase the number of high school students who may be first-generation, lower-socioeconomic, ethnic or non-ethnic. The article identifies three major barriers to successful dual enrollment and completion: state policy, financial issues, and transportation. It also examines how these barriers were eliminated through a collaborative effort. The results demonstrate that over 87% of the juniors and seniors persisted over the semesters, and enrollment tripled among African American and Latino students. The article is constructed to benefit further research and practical application for urban and rural community colleges.  相似文献   

Spatial visualization ability and laparoscopic skills in novice learners: Evaluating stereoscopic versus monoscopic visualizations          下载免费PDF全文

Victoria A. Roach  Manisha R. Mistry  Timothy D. Wilson 《Anatomical sciences education》2014,7(4):295-301

Elevated spatial visualization ability (Vz) is thought to influence surgical skill acquisition and performance. Current research suggests that stereo visualization technology and its association with skill performance may confer perceptual advantages. This is of particular interest in laparoscopic skill training, where stereo visualization may confer learning advantages to novices of variant Vz. This study explored laparoscopic skill performance scores in novices with variable spatial ability utilizing stereoscopic and traditional monoscopic visualization paradigms. Utilizing the McGill Inanimate System for Teaching and Evaluating Laparoscopic Skills (MISTELS) scoring protocol it was hypothesized that individuals with high spatial visualization ability (HVz) would achieve higher overall and individual MISTELS task scores as compared to low spatial visualization ability (LVz) counterparts. Further, we also hypothesized that a difference would exist between HVz and LVz individual scores based on the viewing modality employed. No significant difference was observed between HVz and LVz individuals for MISTELS tasks scores, overall or individually under both viewing modalities, despite higher average MISTELS scores for HVz individuals. The lack of difference between scores obtained under the stereo modality suggested that the additional depth that is conferred by the stereoscopic visualization may act to enhance performance for individuals with LVz, potentially equilibrating their performance with their HVz peers. Further experimentation is required to better ascertain the effects of stereo visualization in individuals of high and low Vz, though it appears stereoscopic visualizations could serve as a prosthetic to enhance skill performance.

Impact of a Statewide Collaborative on Strengthening Families Through Early Care and Education     

Mary Roach  Yae Bin Kim  Cailin O'Connor  Joan Laurion 《Early education and development》2013,24(5):865-879

Research Findings: Research suggests that early care and education programs are most effective when they include strong components of family involvement. The Center for the Study of Social Policy recommended that early care and education programs build family-centered practices to strengthen families and reduce the incidence of child abuse and neglect. This article summarizes a statewide effort to implement this strategy, called Strengthening Families through Early Care and Education. We analyzed program self-assessments submitted by 186 early care and education programs. Analyses revealed that Head Start programs had better support systems in place for families than did “mainstream” (non–Head Start, non-accredited) early care and education programs. Results also showed that a small amount of state and local funding provided enough incentive for programs to improve their family-strengthening practices. Commitment and collaboration at the state level led to a sustainable impact by infusing “strengthening families” concepts into the early care and education field statewide.  相似文献   

Examining the predictive validity of behavior screeners across measures and respondents     

Corey Jones  Emily Graybill  Brian Barger  Andrew T. Roach 《Psychology in the schools》2020,57(6):923-936

Through this study we compared different informants and different behavior screening tools that are available to screen for behavioral and emotional risk. We examined screening results from 100 students from a high school with a high achiever's magnet program in the Southeastern United States (school demographics: 71% female and 79% black, non-Hispanic). This school conducted behavior screening using both teacher-report via the Student Risk Screening Scale, Internalizing/Externalizing (SRSS-IE) and student report via the Strengths and Difficulties Questionnaire (SDQ). Nonparametric correlation tests were conducted between the SRSS-IE and SDQ externalizing and internalizing scores. Generalized linear regression models were created based on the data (demographics, internalizing, and externalizing scores on both screening tools) to model the two count outcomes (office discipline referrals [ODRs] and absences). Diagnostic accuracy metrics were generated from the scores on both the SRSS-IE and SDQ with the outcome measures (ODRs and absences). Externalizing scores on both screening tools had statistically significant low correlations. The ODR model contained two predictors: externalizing score on the SRSS-IE and internalizing score on the SDQ, while the absence model contained grade and the externalizing score on the SDQ. The highest accuracy and agreement values were seen between students with elevated risks on both screening measures and ODRs. The results confirmed that teacher and student reporting, as well as different screening tools, will result in some different students being identified. The choice of informant and screening tools should be dependent on the needs and resources of the school.  相似文献   

Once Attained, Can Quality Child Care Be Maintained?     

Mary A. Roach  YaeBin Kim  David A. Riley 《Early education and development》2006,17(4):553-570

Research Findings: This study was designed to assess whether investments in child care quality were maintained 3 years after public funding for these centers was significantly reduced. An earlier evaluation documented significant improvements in classroom environments, teachers' sensitivity, and teachers' child-centered beliefs following a 15-month state intervention in 24 early care and education programs serving high numbers of children from low-income families. The current study used a quasi-experimental design, with pre- and postdata collected through direct observations and questionnaires in nonrandom treatment and comparison groups. Practice or Policy: Results at the 3-year follow-up showed that the majority (92%) of centers in the intervention group were accredited and that significant improvements in classroom environments were maintained after funding was significantly reduced. However, erosion in more sensitive measures (i.e., teacher sensitivity and child-centered beliefs) during the period of reduced funding suggested some concern that programs serving high concentrations of children from low-income families may require some consistent state support if they are to yield the positive life outcomes desired by economists and policymakers.  相似文献   

Transition services for students with intellectual disabilities: School psychologists’ perceptions     

Devadrita Talapatra  Andrew T. Roach  Kris Varjas  David E. Houchins  Daniel B. Crimmins 《Psychology in the schools》2019,56(1):56-78

For individuals with intellectual disabilities (ID), transition services increase access to postschool opportunities. School psychologists should contribute to transition services but have reportedly limited involvement in this area. This study distributed a national survey (N = 176) assessing school psychologists’ current knowledge, attitudes, and behaviors regarding transition services for students with ID. Results indicated that attitudes toward and knowledge of the ID population were significant predictors of transition task performance, and knowledge was a significant predictor of transition‐related attitudes and behaviors. The results provided preliminary evidence that increasing school psychologists’ specific knowledge of transition services and encouraging positive attitudes toward the transition needs of students with ID may increase school psychologists’ performance in transition practice. Specific recommendations are provided.  相似文献   

Comparison of 3D reconstructive technologies used for morphometric research and the translation of knowledge using a decision matrix     

Charys M. Martin  Victoria A. Roach  Ngan Nguyen  Charles L. Rice  Timothy D. Wilson 《Anatomical sciences education》2013,6(6):393-403

The use of three‐dimensional (3D) models for education, pre‐operative assessment, presurgical planning, and measurement have become more prevalent. With the increase in prevalence of 3D models there has also been an increase in 3D reconstructive software programs that are used to create these models. These software programs differ in reconstruction concepts, operating system requirements, user features, cost, and no one program has emerged as the standard. The purpose of this study was to conduct a systematic comparison of three widely available 3D reconstructive software programs, Amira^®, OsiriX, and Mimics^®, with respect to the software's ability to be used in two broad themes: morphometric research and education to translate morphological knowledge. Cost, system requirements, and inherent features of each program were compared. A novel concept selection tool, a decision matrix, was used to objectify comparisons of usability of the interface, quality of the output, and efficiency of the tools. Findings indicate that Mimics was the best‐suited program for construction of 3D anatomical models and morphometric analysis, but for creating a learning tool the results were less clear. OsiriX was very user‐friendly; however, it had limited capabilities. Conversely, although Amira had endless potential and could create complex dynamic videos, it had a challenging interface. These results provide a resource for morphometric researchers and educators to assist the selection of appropriate reconstruction programs when starting a new 3D modeling project.
