To determine recognition given for outstanding teaching, service, and scholarship at US colleges and schools of pharmacy, the types of awards given, and the process used to select the recipients.
A self-administered questionnaire was made available online in 2006 to deans at 89 colleges and schools of pharmacy.
Sixty-four usable responses (72%) were obtained. An award to acknowledge teaching excellence was most commonly reported (92%), followed by an award for adjunct/volunteer faculty/preceptors (79%). The majority of the institutions (31 out of 58) reported offering 1 teaching award annually. The 2 most common methods for selecting the recipient of the teaching award were by student vote and by college/school committee vote following nominations. Twenty-four of the 63 respondents indicated that their institution provided an award for research/scholarship and 18 offered an award for outstanding service.
Teaching excellence was recognized and rewarded at most US colleges and schools of pharmacy; however, research/scholarship and service were formally recognized less frequently.

Objectives. To identify the prevalence of portfolio use in US pharmacy programs, common components of portfolios, and advantages of and limitations to using portfolios.
Methods. A cross-sectional electronic survey instrument was sent to experiential coordinators at US colleges and schools of pharmacy to collect data on portfolio content, methods, training and resource requirements, and benefits and challenges of portfolio use.
Results. Most colleges and schools of pharmacy (61.8%) use portfolios in experiential courses and the majority (67.1%) formally assess them, but there is wide variation regarding content and assessment. The majority of respondents used student portfolios as a formative evaluation primarily in the experiential curriculum.
Conclusions. Although most colleges and schools of pharmacy have a portfolio system in place, few are using them to fulfill accreditation requirements. Colleges and schools need to carefully examine the intended purpose of their portfolio system and follow-through with implementation and maintenance of a system that meets their goals.

Objective. To determine trends among departments of pharmacy practice regarding use of adjunct faculty members for classroom-based teaching and to assess departmental support provided to these faculty members.
Methods. Chairs of pharmacy practice departments in US colleges and school of pharmacy were contacted by e-mail and asked to complete an 11-item electronic survey instrument.
Results. Chair respondents reported an average of 5.7 adjunct faculty members hired to teach required courses and 1.8 adjunct faculty members hired to teach elective courses. Compensation averaged $108 per lecture hour and $1,257 per 1-credit-hour course. Twenty-five percent of the respondents expected to hire more adjunct faculty members to teach required courses in the upcoming year due to curricular changes, faculty hiring freezes, and the shortage of full-time faculty members. Only 7% of respondents reported that they provided a teaching mentor and 14% offered no support to their adjunct faculty members.
Conclusions. Departments of pharmacy practice commonly use adjunct faculty members to teach required and elective courses. Given the pharmacy faculty shortage, this trend is expected to increase and may be an area for future faculty development.

To describe the extent of psychiatric pharmacy instruction in US pharmacy curricula, including course and faculty characteristics and mental health topics taught in clinical therapeutics-based courses.
An 11-item survey instrument (54% response) was developed and mailed to 91 colleges and schools of pharmacy.
Over 75% of colleges and schools employed a psychiatric pharmacist; however, less than 50% of faculty teaching psychiatric pharmacy content were psychiatric pharmacy specialists as defined in the study. All colleges and schools included psychiatric topics as part of a therapeutics-based course with an average of 9.5% of course content devoted to these topics. About 25% of colleges and schools offered elective didactic courses in psychiatric pharmacy. Only 2 schools required a psychiatric pharmacy advanced pharmacy practice experience (APPE), but about 92% offered elective APPEs. The mean number of hours spent on lecture- and case-based instruction across all colleges and schools was highest for depression and lowest for personality disorders.
There is a need for colleges and schools of pharmacy to better identify and standardize the minimal acceptable level of didactic instruction in psychiatric pharmacy as well as the minimal level of specialty qualifications for faculty members who teach this subject.

The 2008-2009 Task Force for the Recognition of Teaching Excellence was charged by the AACP Council of Faculties Leadership to examine teaching excellence by collecting best practices from colleges and schools of pharmacy, evaluating the literature to identify evidence-based criteria for excellent teaching, and recommending appropriate means to acknowledge and reward teaching excellence. This report defines teaching excellence and discusses a variety of ways to assess it, including student, alumni, peer, and self-assessment. The task force identifies important considerations that colleges and schools must address when establishing teaching recognition programs including the purpose, criteria, number and mix of awards, frequency, type of award, and method of nominating and determining awardees. The report concludes with recommendations for the academy to consider when establishing and revising teaching award programs.

To document the type and extent of active-learning techniques used in US colleges and schools of pharmacy as well as factors associated with use of these techniques.
A survey instrument was developed to assess whether and to what extent active learning was used by faculty members of US colleges and schools of pharmacy. This survey instrument was distributed via the American Association of Colleges of Pharmacy (AACP) mailing list.
Ninety-five percent (114) of all US colleges and schools of pharmacy were represented with at least 1 survey among the 1179 responses received. Eighty-seven percent of respondents used active-learning techniques in their classroom activities. The heavier the teaching workload the more active-learning strategies were used. Other factors correlated with higher use of active-learning strategies included younger faculty member age (inverse relationship), lower faculty member rank (inverse relationship), and departments that focused on practice, clinical and social, behavioral, and/or administrative sciences.
Active learning has been embraced by pharmacy educators and is used to some extent by the majority of US colleges and schools of pharmacy. Future research should focus on how active-learning methods can be used most effectively within pharmacy education, how it can gain even broader acceptance throughout the academy, and how the effect of active learning on programmatic outcomes can be better documented.

To assess the train-the-trainer component of an initiative (Partners in D) to train pharmacy students to facilitate patient enrollment in the best Medicare Part D prescription drug plan (Part D).
Faculty members from 6 California colleges or schools of pharmacy were taught how to train pharmacy students about Medicare Part D and how to conduct outreach events targeting underserved patient populations. A preintervention and postintervention survey instrument was administered to determine participants' (1) knowledge of the Part D program; (2) skill using the Medicare Prescription Drug Plan Finder tool; and (3) confidence in their ability to train pharmacy students. Implementation of the Partners in D curriculum in faculty members' colleges or schools of pharmacy was also determined.
Participants' knowledge of Part D, mastery of the Plan Finder, and confidence in teaching the material to pharmacy students all significantly improved. Within 8 weeks following the program, 5 of 6 colleges or schools of pharmacy adopted Partners in D coursework and initiated teaching the Partners-in-D curriculum. Four months afterwards, 21 outreach events reaching 186 Medicare beneficiaries had been completed.
The train-the-trainer component of the Partners in D program is practical and effective, and merits serious consideration as a national model for educating patients about Medicare Part D.

Objectives. To characterize the use of high-fidelity mannequins and standardized patients in US pharmacy colleges and schools.
Methods. A survey instrument was sent to 105 doctor of pharmacy (PharmD) programs to collect data on the use of simulation and to identify barriers to using simulation-based teaching methods.
Results. Eighty-eight colleges and schools completed the survey instrument (response rate 84%). Of these, 14 did not use high-fidelity mannequins or standardized patients within the curriculum. Top barriers were logistical constraints and high resource cost. Twenty-three colleges and schools used simulation for introductory pharmacy practice experiences (IPPEs), 34 for interprofessional education, and 68 for evaluation of at least 1 core competency prior to advanced pharmacy practice experiences (APPEs).
Conclusions. Although the majority of US colleges and schools of pharmacy use simulation-based teaching methodologies to some extent in the pharmacy curricula, the role of simulation in IPPEs, interprofessional education, and assessment of competency-based skills could be expanded.

A small nonprofit private college with limited resources and a high proportion of junior faculty developed a nontraditional external faculty mentor program in the summer of 2011 in response to the American Association of Colleges of Pharmacy (AACP) faculty survey data regarding the professional development needs of pharmacy faculty members. Experienced faculty members with national reputations from other colleges and schools of pharmacy were hired as consultants to serve as mentors for assigned faculty members. Program goals were to provide directed, individual mentorship for pharmacy practice and basic science faculty members, expand peer review of faculty teaching prowess, and enhance monthly faculty development programming. The latter was based upon the specific needs assessment of the faculty. Program outcomes reported will include faculty satisfaction (AACP faculty survey data) changes over time, achievement of board certification for clinical faculty members and other credentialing, and other benchmarks, eg, publications, grant funding, service engagement (site development, professional organizations), after the implementation of the nontraditional faculty-mentoring program.
Objective. To identify the manner in which colleges and schools of pharmacy in the United States and Puerto Rico assess full-time faculty preceptors.
Methods. Directors of pharmacy practice (or equivalent title) were invited to complete an online, self-administered questionnaire.
Results. Seventy of the 75 respondents (93.3%) confirmed that their college or school assessed full-time pharmacy faculty members based on activities related to precepting students at a practice site. The most commonly reported assessment components were summative student evaluations (98.5%), type of professional service provided (92.3%), scholarly accomplishments (86.2%), and community service (72.3%). Approximately 42% of respondents indicated that a letter of evaluation provided by a site-based supervisor was included in their assessment process. Some colleges and schools also conducted onsite assessment of faculty members.
Conclusions. Most colleges and schools of pharmacy assess full-time faculty-member preceptors via summative student assessments, although other strategies are used. Given the important role of preceptors in ensuring students are prepared for pharmacy practice, colleges and schools of pharmacy should review their assessment strategies for full-time faculty preceptors, keeping in mind the methodologies used by other institutions.

To identify mobile computing initiatives within pharmacy education, including how devices are obtained, supported, and utilized within the curriculum.
An 18-item questionnaire was developed and delivered to academic affairs deans (or closest equivalent) of 98 colleges and schools of pharmacy.
Fifty-four colleges and schools completed the questionnaire for a 55% completion rate. Thirteen of those schools have implemented mobile computing requirements for students. Twenty schools reported they were likely to formally consider implementing a mobile computing initiative within 5 years.
Numerous models of mobile computing initiatives exist in terms of device obtainment, technical support, infrastructure, and utilization within the curriculum. Responders identified flexibility in teaching and learning as the most positive aspect of the initiatives and computer-aided distraction as the most negative, Numerous factors should be taken into consideration when deciding if and how a mobile computing requirement should be implemented.

Objective. To assess the prevalence and characteristics of curriculum in dual doctor of pharmacy (PharmD)/master of public health (MPH) degree programs offered by US pharmacy programs.
Methods. An 18-item survey instrument was developed and distributed online to faculty members at US colleges and schools of pharmacy.
Results. Of the 110 colleges and schools that responded, 23 (21%) offered a PharmD/MPH degree. Common characteristics of these 23 programs included current PharmD program structure (3 + 1 year), early curricular recruitment, small enrollment, and interdisciplinary coursework occurring online and in the classroom. The impact of the dual degree on the curriculum and longevity of the dual-degree programs varied. About 55% of responding programs without a formal dual-degree program reported that additional public health training was available.
Conclusion. Twenty-one percent of colleges and schools of pharmacy offer a combined PharmD/MPH dual degree. Most programs required an additional 1 or 2 semesters to complete both degrees.

Objective. To develop and assess the impact of an elective course (HealthWISE) on student pharmacists’ skills in communication and health promotion and elementary school students’ knowledge of and attitudes toward science.
Design. Three colleges and schools of pharmacy collaborated to develop a 1-credit elective course that used online and classroom teaching and learning techniques to prepare student pharmacists to teach science in elementary school classrooms. Student pharmacists delivered 6 science lessons to elementary students over the course of 2 months.
Assessment. In weekly journal reflections and a final paper, student pharmacists reported improved communication and health promotion skills. Elementary teachers reported they were satisfied with student pharmacists’ performance in the classroom. On pretest and posttest evaluations, elementary students demonstrated increased science knowledge and enhanced enthusiasm for science following the lessons taught by student pharmacists.
Conclusions. The HealthWISE elective course provided positive benefit for student pharmacists, elementary school teachers, and elementary students.

Formal guidelines for mentoring faculty members in pharmacy practice divisions of colleges and schools of pharmacy do not exist in the literature. This paper addresses the background literature on mentoring programs, explores the current state of mentoring programs used in pharmacy practice departments, and provides guidelines for colleges and schools instituting formal mentoring programs. As the number of pharmacy colleges and schools has grown, the demand for quality pharmacy faculty members has dramatically increased. While some faculty members gain teaching experience during postgraduate residency training, new pharmacy practice faculty members often need professional development to meet the demands of their academic responsibilities. A mentoring program can be 1 means of improving faculty success and retention. Many US colleges and schools of pharmacy have developed formal mentoring programs, whereas several others have informal processes in place. This paper discusses those programs and the literature available, and makes recommendations on the structure of mentoring programs.

Objective. To assess pharmacy faculty trainers’ perceptions of a Web-based train-the-trainer program for PharmGenEd, a shared pharmacogenomics curriculum for health professional students and licensed clinicians.
Methods. Pharmacy faculty trainers (n=58, representing 39 colleges and schools of pharmacy in the United States and 1 school from Canada) participated in a train-the-trainer program consisting of up to 9 pharmacogenomics topics. Posttraining survey instruments assessed faculty trainers’ perceptions toward the training program and the likelihood of their adopting the educational materials as part of their institution’s curriculum.
Results. Fifty-five percent of faculty trainers reported no prior formal training in pharmacogenomics. There was a significant increase (p<0.001) in self-reported ability to teach pharmacogenomics to pharmacy students after participants viewed the webinar and obtained educational materials. Nearly two-thirds (64%) indicated at least a “good” likelihood of adopting PharmGenEd materials at their institution during the upcoming academic year. More than two-thirds of respondents indicated interest in using PharmGenEd materials to train licensed health professionals, and 95% indicated that they would recommend the program to other pharmacy faculty members.
Conclusion. As a result of participating in the train-the-trainer program in pharmacogenomics, faculty member participants gained confidence in teaching pharmacogenomics to their students, and the majority of participants indicated a high likelihood of adopting the program at their institution. A Web-based train-the-trainer model appears to be a feasible strategy for training pharmacy faculty in pharmacogenomics.

Current hospital and health-system participation in and the future capacity for experiential education for pharmacy students was investigated.
An online survey of ASHP members identified as U.S. pharmacy directors was conducted to assess their current and future involvement in partnering with colleges and schools to meet the experiential education requirements for doctor of pharmacy students and the current status of the student learning experiences. Questionnaire items examined the factors on which expanded involvement in experiential education would depend, the nature of support provided by colleges and schools, the types of experiences available for students, respondents' perceptions of factors influencing the quality of experiential education, the value of experiential education to the sites, respondents' challenges and concerns about experiential education, and respondents' current capacity and projections for introductory and advanced experiences through 2012.
Data from 549 respondents were analyzed. Most respondents indicated that they had conducted advanced experiences for their 2007 graduates and anticipated that they would continue to do so. Among the top challenges identified regarding advanced experiences were concerns about time to serve and be trained as preceptors and a lack of standardization and coordination among colleges and schools. Hospitals forecasting their future capacity to accommodate students indicated that their projections were highly dependent on the number of pharmacists at their hospitals. Many respondents noted that their capacity projections were tied to their ability to expand clinical services at their hospitals.
A survey of pharmacy directors suggested an ability of U.S. hospitals to conduct advanced experiential education opportunities for pharmacy students through 2012 and to expand introductory experiences.

Objective. To assess financial, personnel, and curricular characteristics of US pharmacy practice experiential education programs and follow-up on results of a similar survey conducted in 2001.
Methods. Experiential education directors at 118 accredited US pharmacy colleges and schools were invited to participate in a blinded, Web-based survey in 2011. Aggregate responses were analyzed using descriptive statistics and combined with data obtained from the American Association of Colleges of Pharmacy to assess program demographics, faculty and administrative organizational structure, and financial support.
Results. The number of advanced pharmacy practice experience (APPE) sites had increased by 24% for medium, 50% for large, and 55% for very large colleges and schools. Introductory pharmacy practice experience (IPPE) sites outnumbered APPEs twofold. The average experiential education team included an assistant/associate dean (0.4 full-time equivalent [FTE]), a director (1.0 FTE), assistant/associate director (0.5 FTE), coordinator (0.9 FTE), and multiple administrative assistants (1.3 FTE). Most faculty members (63%-75%) were nontenure track and most coordinators (66%) were staff members. Estimated costs to operate an experiential education program represented a small percentage of the overall expense budget of pharmacy colleges and schools.
Conclusion. To match enrollment growth, pharmacy practice experiential education administrators have expanded their teams, reorganized responsibilities, and found methods to improve cost efficiency. These benchmarks will assist experiential education administrators to plan strategically for future changes.

To evaluate the research-related coursework and research experiences in doctor of pharmacy programs and compare the findings to those of 2 previous studies.
A questionnaire was mailed to 88 colleges and schools of pharmacy in the United States and Puerto Rico. The survey instrument sought information on formal research-related coursework; required and elective research experiences; and perceptions of student-conducted research.
Seventy-nine colleges and schools completed the questionnaire for a response rate of 88%. Most colleges (>90%) required students to study/complete courses in biostatistics and drug information/literature evaluation; approximately half required research methods coursework. Twenty-five percent required some form of project and requirements were not influenced by class size. Students could often work in teams to complete projects. Respondents generally thought participation in research had some value for motivated students.
This study demonstrates the variability in extent of research-related coursework and research experiences in PharmD programs across the country.

Objective. To evaluate the characteristics of experiential education Web sites of colleges and schools of pharmacy in the United States.
Methods. The experiential education Web pages of 124 US colleges and schools of pharmacy were reviewed for office or program name, practice experience management software, experiential education newsletter, practice experience manual, preceptor development programs, new preceptor application processes, and interactive Web site interfaces.
Results. The term “office of experiential education” was used by 27.4% of colleges and schools. Fifty percent of the colleges and schools used E-value as their practice experience management software. Only a minority of colleges and schools made experiential manual(s) available online, offered newsletters targeted to preceptors, and/or provided Web site interactive interfaces for preceptor communication. The Preceptors Training and Resource Network was the preceptor development program most frequently promoted.
Conclusions. The majority of US colleges and schools of pharmacy have official Web sites for their experiential education program; however, few offer resources online or use interactive or social media to their advantage.

To evaluate the effectiveness of a problem-based learning (PBL) model implemented in 1995 at the University of Mississippi School of Pharmacy.
The third-professional (P3) year curriculum was reoriented from a faculty-centered model of teaching to a student-centered model of learning. Didactic lectures and structured classroom time were diminished. Small student groups were organized and a faculty facilitator monitored each group's discussions and provided individual student assessments. At the end of each 8-week block, students were assessed on group participation, disease and drug content knowledge, and problem-solving abilities. Faculty and student input was solicited at the end of each year to aid programmatic improvement. In 2000, a formal 5-year review of the PBL program was conducted.
Recommendations for improvement included clarifying course objectives, adopting a peer-review process for examination materials, refining the group assessment instruments, and providing an opportunity for student remediation after a course was failed. A weekly case conference presided over by a faculty content expert was also recommended. Ongoing critical evaluation during the following 5-year period was provided by graduates of the program, faculty participants, and accreditation reviews.
Over our 10-year experience with a PBL model of P3 education, we found that although the initial challenges of increased demands on personnel and teaching space were easily overcome, student acceptance of the program depended on their acknowledgment of the practical benefits of active learning and on the value afforded their input on curricular development.

Objective. To compare the science of safety (SoS) topic coverage and associated student competencies in the experiential education curricula of colleges and schools of pharmacy in the United States and Taiwan.
Methods. The experiential education director, assistant director, or coordinator at a random sample of 34 US colleges and schools of pharmacy and all 7 Taiwan schools of pharmacy were interviewed and then asked to complete an Internet-based survey instrument.
Results. Faculty members in both countries perceived that experiential curricula were focused on the postmarketing phase of the SoS, and that there is a need for the pharmacy experiential curricula to be standardized in order to fill SoS coverage gaps. Inter-country differences in experiential SoS coverage were noted in topics included for safety biomarkers that signal potential for drug-induced problems and pharmacogenomics.
Conclusions. Experiential SoS topic coverage and student ability gaps were perceived within and between US and Taiwan colleges and schools of pharmacy.

This paper provides baseline information on integrating the science of safety into the professional degree curriculum at colleges and schools of pharmacy. A multi-method examination was conducted that included a literature review, key informant interviews of 30 individuals, and in-depth case studies of 5 colleges and schools of pharmacy. Educators believe that they are devoting adequate time to science of safety topics and doing a good job teaching students to identify, understand, report, manage, and communicate medication risk. Areas perceived to be in need of improvement include educating pharmacy students about the Food and Drug Administration's (FDA's) role in product safety, how to work with the FDA in post-marketing surveillance and other FDA safety initiatives, teaching students methods to improve safety, and educating students to practice in interprofessional teams. The report makes 10 recommendations to help pharmacy school graduates be more effective in protecting patients from preventable drug-related problems.

Objectives. To gather and evaluate the perceptions of students, faculty members, and administrators regarding the frequency and appropriateness of classroom technology use.
Methods. Third-year pharmacy students and faculty members at 6 colleges and schools of pharmacy were surveyed to assess their perceptions about the type, frequency, and appropriateness of using technology in the classroom. Upper-level administrators and information technology professionals were also interviewed to ascertain overall technology goals and identify criteria used to adopt new classroom technologies.
Results. Four hundred sixty-six students, 124 faculty members, and 12 administrators participated in the survey. The most frequently used and valued types of classroom technology were course management systems, audience response systems, and lecture capture. Faculty members and students agreed that faculty members appropriately used course management systems and audience response systems. Compared with their counterparts, tech-savvy, and male students reported significantly greater preference for increased use of classroom technology. Eighty-six percent of faculty members reported having changed their teaching methodologies to meet student needs, and 91% of the students agreed that the use of technology met their needs.
Conclusions. Pharmacy colleges and schools use a variety of technologies in their teaching methods, which have evolved to meet the needs of the current generation of students. Students are satisfied with the appropriateness of technology, but many exhibit preferences for even greater use of technology in the classroom.

Objective. To describe the integration of science of safety (SoS) topics in doctor of pharmacy (PharmD) curricula of US colleges and schools of pharmacy.
Methods. A questionnaire that contained items pertaining to what and how SoS topics are taught in PharmD curricula was e-mailed to representatives at 107 US colleges and schools of pharmacy.
Results. The majority of the colleges and schools responding indicated that they had integrated SoS topics into their curriculum, however, some gaps (eg, teaching students about communicating risk, Food and Drug Administration [FDA] Sentinel Initiative, utilizing patient databases) were identified that need to be addressed.
Conclusions. The FDA and the American Association of Colleges of Pharmacy (AACP) should continue to collaborate to develop resources needed to ensure that topics proposed by the FDA in their SoS framework are taught at all colleges and schools of pharmacy.
