Young adolescent psychological need profiles: Associations with classroom achievement and well‐being     

Stephen R. Earl  Ian M. Taylor  Carla Meijen  Louis Passfield 《Psychology in the schools》2019,56(6):1004-1022

Drawing on self‐determination theory, a person‐centered methodology was adopted to identify distinct pupil profiles based on their psychological need satisfaction. A sample of 586 pupils (387 male, 199 female; mean age = 12.6, range 11–15 years old) from three secondary schools reported their psychological need satisfaction, and well‐ and ill‐being, with teachers rating pupil achievement. Hierarchical cluster analysis revealed five distinct profiles. Four profiles indicated synergy existed between the three needs, showing similar in‐group levels of satisfaction across the needs but in varying amounts. Univariate and multivariate analyses, controlling for school and taught subject, revealed the satisfied group displayed the highest classroom performance (F_4,540 = 7.03; p < 0.001; η_p² = 0.05), well‐being (F_8,1,136 = 45.63; p < 0.001; Wilk's Λ = 0.57; η_p² = 0.24) and lowest ill‐being (F_8,1,134 = 23.39; p < 0.001; Wilk's Λ = 0.74, η_p² = 0.14), whereas the dissatisfied group displayed the most adverse outcomes. The findings illustrate that the three psychological needs may operate interdependently and should be considered in combination rather than in isolation. The research offers practical insights into why pupils may function differently in classrooms and could inform targeted initiatives towards pupils with psychological need satisfaction deficits.  相似文献   

Scaffolding reflection and articulation of scientific explanations in a data-rich,project-based learning environment: An investigation of progress portfolio     

Susan M. Land  Carla Zembal-Saul 《Educational technology research and development : ETR & D》2003,51(4):65-84

In this study, we examined how learners developed scientific explanations about light with the assistance of various technology-based scaffolds. The study emphasis was on scaffolding processes of reflection and articulation. We used a content-neutral software program (Progress Portfolio) to create the instructional scaffolds. A qualitative research design was used to investigate two pairs of prospective teachers in a science content course in engineering. Our findings suggested that the computer-based scaffolds used in our study were useful to support articulation, reflection, and revision of explanations, when certain conditions were met. A major theme of our findings relates to interacting effects among learner characteristics, teacher coaching, software scaffolding design, and task characteristics. This material is based on work supported by the National Science Foundation under NSF REC 9980055, which was granted to the second author. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of the National Science Foundation.

A Twin Study of Attachment in Preschool Children   总被引：3，自引：0，他引：3  

Thomas G. O''Connor  & Carla M. Croft 《Child development》2001,72(5):1501-1511

The degree to which individual differences in child-parent attachment were mediated by genetic, shared environmental, and nonshared environmental influences was investigated. One hundred and ten preschool-aged twin pairs (N = 220) were assessed in the Strange Situation and coded using conventional four-way classifications and a continuous measure of attachment security. The degree of sibling similarity in attachment was substantial, with an overall concordance rate of 67% at the secure/insecure level. The degree of concordance was equally high in monozygotic and dizygotic twin pairs, 70% and 64%, respectively, suggesting little genetic influence but a moderate degree of discordance. Twin similarity on the continuous measure of attachment security was r(57) = .48 and r(53) = .38 for monozygotic and dizygotic twin pairs, respectively, also consistent with a modest role for genetic influence but a significant effect for shared and nonshared environment. The implications for genetic influences on the environment and for understanding nonshared and shared environmental influences are discussed.  相似文献   

Recovery of conditioned suppression after backward pairings     

Douglas A. Williams  Carla A. Sly 《Learning & behavior》1999,27(2):152-167

In four conditioned suppression experiments with rats (Rattus norvegicus), backward pairings of a shock unconditioned stimulus (US) and a tone conditioned stimulus (CS) eliminated an already established conditioned response (CR), but there was recovery of the CR if the shock was later withheld. In Experiment 1, there was recovery after backward pairings, regardless of whether the period after the US was normally shock free or not. In Experiment 2, the occurrence of recovery depended on the CS’s being presented closely after the US in response elimination. Levels of recovery were positively correlated with the resistance of the response to elimination during backward pairings (Experiments 3 and 4). Taken together, these data support the notion that recovery after backward pairings is a form of renewal (see, e.g., Bouton, 1991) and is not due toprotection from extinction.  相似文献   

Children’s use of drawing as a pre-writing strategy     

Edith Norris  Kouider Mokhtari  Carla Reichard 《Journal of Research in Reading》1998,21(1):69-74

In this study the writing products of 60 third-grade students, who drew before writing a story on a self-selected topic, was compared with the writing products of 59 third-grade students who wrote without drawing. The students in the group which drew before writing tended to produce more words, more sentences and more idea units, and their overall writing performance was higher than the students who wrote without drawing. These findings were consistent for boys as well as girls. Implications for writing research and instruction are discussed.  相似文献

School psychologists' perceptions of priorities for dealing with the dropout problem     

Carla J. Egyed  David E. McIntosh  Kay S. Bull 《Psychology in the schools》1998,35(2):153-162

A sample of 444 (245 males and 199 females) Nationally Certified School Psychologists were surveyed to determine which causes of dropping out should be national priorities. A Principal Axis Factoring with oblimin rotation was conducted using the 42-item School Psychologist's Dropout Survey. The five factors which emerged were Criminal/Victimization, Different from Peer Group, School Conflict, Dysfunctional Family/Lack of Support, and Family Responsibilities. The factors comprised of items with loadings of .40 or higher were added together for each factor to obtain subscale total scores for each participant. Then, for each subscale all total scores were added together and divided by 444 to obtain an average subscale total score for the entire sample. This process was followed for all five subscales. Finally, the average subscale scores were ranked to identify which causes of dropping out were viewed by school psychologists as the most important national priority. School psychologists perceived school conflicts and dysfunctional families as the primary causes of dropping out that should be national priorities. © 1998 John Wiley & Sons, Inc.  相似文献   

The Health Information Literacy Research Project     

Jean P. Shipman  Sabrina Kurtz-Rossi  Carla J. Funk 《Journal of the Medical Library Association》2009,97(4):293-301

Objectives:

This research studied hospital administrators'' and hospital-based health care providers'' (collectively, the target group) perceived value of consumer health information resources and of librarians'' roles in promoting health information literacy in their institutions.

Methods:

A web-based needs survey was developed and administered to hospital administrators and health care providers. Multiple health information literacy curricula were developed. One was pilot-tested by nine hospital libraries in the United States and Canada. Quantitative and qualitative methods were used to evaluate the curriculum and its impact on the target group.

Results:

A majority of survey respondents believed that providing consumer health information resources was critically important to fulfilling their institutions'' missions and that their hospitals could improve health information literacy by increasing awareness of its impact on patient care and by training staff to become more knowledgeable about health literacy barriers. The study showed that a librarian-taught health information literacy curriculum did raise awareness about the issue among the target group and increased both the use of National Library of Medicine consumer health resources and referrals to librarians for health information literacy support.

Conclusions:

It is hoped that many hospital administrators and health care providers will take the health information literacy curricula and recognize that librarians can educate about the topic and that providers will use related consumer health services and resources.

Highlights

• Health care providers responded positively to a health information literacy curriculum offered by librarians and to related resources and services, namely MedlinePlus and the information referral system known as Information Rx.
• Participation in a curriculum increased health care providers'' knowledge of health information literacy, awareness of available consumer health information, and referral of patients to the library for additional assistance.
• Librarian involvement in health information literacy increased the profession''s visibility and perceived value.

Implications

• Consumer health information services and resources offered by librarians can improve the health information literacy skills of health care providers and their patients.
• Training by librarians can increase knowledge of the importance of health information literacy and usage of MedlinePlus and Information Rxs.
• Hospital-based administrators and health care providers can be champions in support of health information literacy and consumer health information services offered by libraries.

Vital pathways for hospital librarians: present and future roles     

Ruth Holst  Carla J. Funk  Heidi Sue Adams  Margaret Bandy  Catherine Mary Boss  Beth Hill  Claire B. Joseph  Rosalind K. Lett 《Journal of the Medical Library Association》2009,97(4):285-292

Objectives:

The research objectives were to (1) describe the current and future roles of hospital librarians and the challenges they face and (2) find evidence supporting the hypothesis that librarians are essential to hospitals in achieving the organizations'' mission-critical goals.

Method:

The authors used results from a previous research study that identified the five organizational mission-critical goals important to hospital administrators and then searched the literature and solicited examples from hospital librarians to describe the librarian''s role in helping hospitals achieve these goals.

Results:

The literature supports the hypothesis that hospital librarians play important roles in the success of the hospital. Librarians support quality clinical care, efficient and effective hospital operations, continuing education for staff, research and innovation, and patient, family, and community health information needs.

Conclusion:

Hospital librarians fulfill many mission-critical roles in today''s hospital, providing the right information at the right time in a variety of ways to enhance hospital and medical staff effectiveness, optimize patient care, improve patient outcomes, and increase patient and family satisfaction with the hospital and its services. Because hospital librarians and their services provide an excellent return on investment for the hospital and help the hospital keep its competitive edge, hospital staff should have access to the services of a professional librarian.

Highlights

• A review of the literature supports the hypothesis that services of the professional librarian result in:
  • enhanced staff effectiveness,
  • optimized patient care,
  • improved patient outcomes, and
  • increased patient and family satisfaction with the hospital and its services.

Implications

• Because hospital librarians and their services provide an excellent return on investment for the hospital and help the hospital keep its competitive edge, hospital staff should have access to the services of a professional librarian.

Incorporating radiology into medical gross anatomy: Does the use of cadaver CT scans improve students' academic performance in anatomy?     

Rebecca S. Lufler  Ann C. Zumwalt  Carla A. Romney  Todd M. Hoagland 《Anatomical sciences education》2010,3(2):56-63

Radiological images show anatomical structures in multiple planes and may be effective for teaching anatomical spatial relationships, something that students often find difficult to master. This study tests the hypotheses that (1) the use of cadaveric computed tomography (CT) scans in the anatomy laboratory is positively associated with performance in the gross anatomy course and (2) dissection of the CT‐scanned cadaver is positively associated with performance on this course. One hundred and seventy‐nine first‐year medical students enrolled in gross anatomy at Boston University School of Medicine were provided with CT scans of four cadavers, and students were given the opportunity to choose whether or not to use these images. The hypotheses were tested using logistic regression analysis adjusting for student demographic characteristics. Students who used the CT scans were more likely to score greater than 90% as an average practical examination score (odds ratio OR 3.6; 95% CI 1.4, 9.2), final course grade (OR 2.6; 95% CI 1.01, 6.8), and on spatial anatomy examination questions (OR 2.4; 95% CI 1.03, 5.6) than were students who did not use the CT scans. There were no differences in performance between students who dissected the scanned cadavers and those who dissected a different cadaver. These results demonstrate that the use of CT scans in medical gross anatomy is predictive of performance in the course and on questions requiring knowledge of anatomical spatial relationships, but it is not necessary to scan the actual cadaver dissected by each student.
