Growing the tree of teacher knowledge: Ten years of learning to teach elementary science

Abstract: Pedagogical content knowledge (PCK) is a much debated and studied construct. In this article, we adopt an all-embracing view of PCK to examine the development of one elementary science teacher's knowledge over a 10-year period. We portray this teacher's knowledge at three critical points in her career—as a student teacher, beginning teacher, and established teacher—and represent and analyze the growth of her science PCK using the metaphor of a knowledge tree. The tree metaphor shows that while science knowledge begins as the major branch of science PCK, it is soon overshadowed by the general teaching and interactive knowledge branches of science PCK; however, taken together, all three branches contribute over time to the formation of a healthy, established tree of science PCK. © 2005 Wiley Periodicals, Inc.

The effect of pharmacist-provided non-dispensing services on patient outcomes, health service utilisation and costs in low- and middle-income countries.

Abstract: Background The role of pharmacists has expanded beyond dispensing and packaging over the past two decades, and now includes ensuring rational use of drugs, improving clinical outcomes and promoting health status by working with the public and other healthcare professionals. Objectives To examine the effect of pharmacist-provided non-dispensing services on patient outcomes, health service utilisation and costs in low- and middle-income countries. Search methods Studies were identified by electronically searching the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (February 2010), MEDLINE (1949 to February 2010), Scopus (1960 to March 2010) and International Pharmaceutical Abstracts (1970 to January 2010) databases. An update of this review is currently ongoing. The search was re-run September 2012 and the potentially relevant studies are awaiting classification. Selection criteria Randomised controlled trials, non-randomised controlled trials, controlled before-after studies and interrupted time series analyses comparing 1. pharmacist-provided non-dispensing services targeted at patients versus (a) the same services provided by other healthcare professionals, (b) the same services provided by untrained health workers, and (c) usual care; and 2. pharmacist-provided non-dispensing services targeted at healthcare professionals versus (a) the same services provided by other healthcare professionals, (b) the same services provided by untrained health workers, and (c) usual care in low- and middle-income countries. The research sites must have been located in low or middle income countries according to World Bank Group 2009 at the time of the study, regardless of the location or the origin of the researchers. Data collection and analysis Two authors independently reviewed studies for inclusion in the review. Two review authors independently extracted data for each study. Risk of bias of the included studies was also assessed independently by two authors. Main results Twelve studies comparing pharmacist-provided services versus usual care were included in this review. Of the 12 studies, seven were from lower middle income countries and five were from upper middle income countries. Eleven studies examined pharmacist-provided services targeted at patients and one study evaluated pharmacist interventions targeted at healthcare professionals. Pharmacist-provided services targeting patients resulted in a small improvement of clinical outcomes such as blood pressure (-25 mm Hg/-6 mm Hg and -4.56 mm Hg/-2.45 mm Hg), blood glucose (-39.84 mg/dl and -16.16 mg/dl), blood cholesterol (-25.7 mg/dl)/ triglyceride levels (-80.1 mg/dl) and asthma outcomes (peak expiratory flow rate 1.76 l/min). Moreover, there was a small improvement in the quality of life, although four studies did not report the effect size explicitly. Health service utilisation, such as rate of hospitalisation and general practice and emergency room visits, was also found to be reduced by the patient targeted pharmacist-provided services. A single study examined the effect of patient targeted pharmacist interventions on medical expenses and the cost was found to be reduced. A single study that examined pharmacist services that targeted healthcare professionals demonstrated a very small impact on asthma symptom scores. No studies assessing the impact of pharmacist-provided non-dispensing services that targeted healthcare professionals reported health service utilisation and cost outcomes. Overall, five studies did not adequately report the numerical data for outcomes but instead reported qualitative statements about results, which prevented an estimation of the effect size. Studies for the comparison of patient targeted services provided by pharmacists versus the same services provided by other healthcare professionals or untrained healthcare workers were not found. Similarly, studies for the comparison of healthcare professional targeted services provided by pharmacists versus the same services provided by other healthcare professionals or untrained healthcare workers were not found. Authors' conclusions Pharmacist-provided services that target patients may improve clinical outcomes such as management of high glucose levels among diabetic patients, management of blood pressure and cholesterol levels and may improve the quality of life of patients with chronic conditions such as diabetes, hypertension and asthma. Pharmacist services may reduce health service utilisation such as visits to general practitioners and hospitalisation rates. We are uncertain about the effect of educational sessions by pharmacists for healthcare professionals due to the imprecision of a single study included in this review. Similarly, conclusions could not be drawn for health service utilisation and costs due to lack of evidence on interventions delivered by pharmacists to healthcare professionals. These results were heterogenous in the types of outcomes measured, clinical conditions and approaches to measurement of outcomes, and require cautious interpretation. All eligible studies were from middle income countries and the results may not be applicable to low income countries.

Moderated online social therapy: Designing and evaluating technology for mental health

Abstract: Although the use and prevalence of Web-based mental health applications have grown over the past decade, many of these services suffer high rates of attrition. This is problematic, as face-to-face support for mental health is limited. To determine appropriate design guidelines for increasing engagement, we conducted a study of First-Episode Psychosis (FEP) patients and reviewed theories on the use of existing online services. We produced a set of design goals, developed an online application that combined social networking and online therapy within a clinician-moderated site, and conducted a 6-week trial with a group of young FEP patients. The design goals, based on existing theory including Supportive Accountability and Positive Psychology, are operationlised through a model we call Moderated Online Social Therapy (MOST). The trial results indicate that our implementation achieved the design goals and that the MOST model can inform the development of more effective and engaging online therapies.

Relationships between the neighborhood environment and depression in older adults: A systematic review and meta-analysis

Abstract: Background:While depression is a growing public health issue, the percentage of individuals with depression receiving treatment is low. Physical and social attributes of the neighborhood may influence the level of depressive symptoms and the prevalence of depression in older adults.Methods:This review systematically examined the literature on neighborhood environmental correlates of depression in older adults. Findings were analyzed according to three depression outcomes: depressive symptoms, possible depression, and clinical depression. Based on their description in the article, environmental variables were assigned to one of 25 categories. The strength of evidence was statistically quantified using a meta-analytical approach with articles weighted for sample size and study quality. Findings were summarized by the number of positive, negative, and statistically non-significant associations by each combination of environmental attribute – depression outcome and by combining all depression outcomes.Results:Seventy-three articles met the selection criteria. For all depression outcomes combined, 12 of the 25 environmental attribute categories were considered to be sufficiently studied. Three of these, neighborhood socio-economic status, collective efficacy, and personal/crime-related safety were negatively associated with all depression outcomes combined. Moderating effects on associations were sparsely investigated, with 52 articles not examining any. Attributes of the physical neighborhood environment have been understudied.Conclusion:This review provides support for the potential influence of some neighborhood attributes on population levels of depression. However, further research is needed to adequately examine physical attributes associated with depression and moderators of both social and physical neighborhood environment attribute – depression outcome associations.
