Getting the Word Out: Teaching Middle-School Children about Cardiovascular Disease

Cardiovascular disease (CVD) has roots in childhood; since CVD begins early, a clear strong case for early education focused on CVD primary prevention exists. Scientists are not traditionally involved in disseminating health knowledge into public education. Similarly, public school teachers typically do not have access to biomedical research that may increase their students' health science literacy. One way to bridge the 'cultural' gap between researchers and school teachers is to form science education partnerships. In order for such partnerships to be successful, teams of scientists and teachers must 'translate' biomedical research into plain language appropriate for students.In this article, we briefly review the need for improving health literacy, especially through school-based programs, and describe work with one model scientist/teacher partnership, the Teacher Enrichment Initiatives. Examples of cardiovascular research 'translated' into plain language lessons for middle school students are provided and practical considerations for researchers pursuing a science education partnership are delineated.

Do Middle School Students Really Have Fixed Images of Elders?

OBJECTIVE

The purpose of this study was to determine whether combinations of characteristics, abstracted from drawings of elders made by middle school students, grouped together to form cohesive perceptions, or stereotypes, of human aging.

METHODS

We abstracted 49 characteristics from drawings of elders made by 1,944 students at two middle schools in San Antonio, Texas, at the beginning of the 1998-1999 school year. Correlational and factor analyses were used to determine if there was an underlying structure or grouping to the characteristics. Logistic regression was used to determine the variables associated with the investigators' classification of the images as positive, neutral, or negative.

RESULT

The standardized alpha coefficient for the 49 variables was low (alpha = 0.37). The Spearman rho correlations between the variables were also low, with 90.2% of the 1,176 comparisons being < 0.10. Exploratory factor analyses did not provide a useful grouping of characteristics drawn by the students, including analyses stratified by gender and restricted to the most common 34 characteristics. Among the 49 characteristics that emerged from the drawings, 11, 4, and 11 traits were directly associated with classifying the drawings as positive, neutral, or negative, respectively.

DISCUSSION

These analyses indicate that middle school students have not formed strong images regarding aging: No clear cohesive stereotypes of elders emerged from the images drawn by these children. Absence of stereotypic views implies that middle school students may not have a built-in bias toward older people and age-associated changes. This suggests that young adolescents are at a point where instruction including gerontological content can be used to effectively teach about aging and health promotion.

Sentence Completion to Assess Children's Views About Aging

PURPOSE

Sentence completion exercises require students to give open-ended responses to prompts. The first purpose of this article is to describe the method of sentence completion to assess middle-school children's attitudes and beliefs about aging. The second purpose is to describe the patterns of characteristics that children associate with aging.

DESIGN AND METHODS

Two middle schools in San Antonio, TX agreed to have their students participate in the sentence completion exercises at the beginning of the 1998-1999 school year. Teachers asked students to write responses to the following prompts: "Old is.," "You know you are old when.," "You know your parents are old when.," "When I am old, I.," and "Old people." We coded the responses for their characteristics and whether they were positive, negative, or neutral.

RESULTS

Of the 2,476 students, 1,874 (75.6%) wrote responses to at least one prompt. Overall, we collected 3,700 responses and coded 9,438 characteristics (2.6 characteristics per response). The most common characteristics of aging were having wrinkles (21.1%), having gray hair or being bald (20.0%), and being less active (17.5%). Students had a much more positive view of their future (55.4%) compared with their view of aging elicited by the other prompts (range of 4.9-25.7% positive responses). Students infrequently associated old age with specific conditions; only 4.6% mentioned diseases, 6.0% mentioned being ill or taking medications, and 5.7% mentioned sensory problems.

IMPLICATIONS

Middle-school students view their futures much more positively than the changes they observe in their parents and other elders. Students infrequently identified specific diseases or impairments as responsible for the changes they observe with aging. These observed responses provide a starting point for educators to develop and deliver gerontologically based materials that teach about healthful habits to maintain independence across a life span.

The Positively Aging teaching materials improve middle school students' images of older people

PURPOSE

The Positively Aging program is an innovative set of interdisciplinary teaching materials that uses examples from geriatrics and gerontology to teach sixth through eighth grade curricular elements. The purpose of this study was to determine if use of the Positively Aging teaching materials by regular classroom teachers could change middle school students' images of elders.

DESIGN AND METHODS

At the beginning of the 1998-1999 school year, students at two San Antonio, Texas, middle schools were asked to draw a typical older person. These drawings were coded as positive, neutral, or negative portrayals of elders. One school then used the Positively Aging materials as part of the curriculum; the other school served as the control. Second drawings were obtained from the students at the end of the school year and compared to those from baseline.

RESULTS

Both drawings were completed by 60% of students at the intervention school and 55% of students at the control school. Of the 782 paired drawings from the intervention school, 34% were more positive at Time 2 compared to 25% of 591 paired drawings from the control school (chi2 = 13.9, p < .001). In addition, only 20% of the second drawings from the intervention school were more negative than the first drawing compared to 27% from the control school (chi2 = 11.3, p < .001). Using a generalized logit model, we adjusted for each student's baseline drawing (positive-neutral-negative), grade level, gender, ethnic group, and socioeconomic status. After adjustment, students in the intervention school were more likely to draw positive (odds ratio [OR] 1.48, 95% confidence interval [CI] 1.13, 1.94) or positive and neutral images (OR 1.58, 95% CI 1.21, 2.19) at follow-up compared to the control school.

IMPLICATIONS

This controlled study demonstrated that use of the Positively Aging teaching materials and activities moved middle school students toward a more positive view of elders. Interdisciplinary teaching materials based on geriatrics and gerontology can be successfully developed and tested in public school systems to affect attitudes about aging.
