A Critique of “STEM” Education

Science & Education - While a mutually agreed-upon definition of STEM education remains elusive, there is no doubt that instructional models and ideas put forward with the STEM label have had a...     

TEST ITEM ARRANGEMENT, TESTING TIME, AND PERFORMANCE

Two experiments were conducted to determine if a relationship exists between test item arrangements and student performance on power tests. The primary hypotheses were: item arrangements based upon item difficulty, similarity of content, or order of class presentation do not influence test score or required testing time. In the first experiment 122 subjects were randomly assigned to three item difficulty arrangements of 139 test items with a 0–100% difficulty range, and in the second experiment 156 subjects were randomly assigned to three item content arrangements of 103 items. Results of analyses of variance with test anxiety used as a classification factor supported the hypotheses.     

A treatment program for failure to thrive: A cost/effectiveness analysis

Failure to thrive (FTT) is a frequent cause for the admission of infants to the hospital. Such hospitalizations are often lengthy and expensive, and usually do not contribute to an understanding of the etiology of FTT. Generally, organic causes of FTT can be ruled out by a thorough history and physical examination. In this study two groups were examined: 17 infants who were admitted to foster medical placement homes (MPH), private homes with specially trained parents; and a comparison group of 18 infants who were treated in a more traditional way with diagnostic hospitalization. The groups were similar in all regards prior to admission. All infants were less than a year of age. Family disruption was a prominent feature in both groups, but socio-demographic analysis showed them to be similar in all areas studied. The comparison group gained an average of 276 grams in the hospital over 8.6 days. The MPH group gained 362 grams in the hospital over 8.7 days, with an additional 1270 grams in the medical placement home over 31.1 days. Five children were admitted to the medical placement home without hospitalization. After correcting for an expected weight gain of 15 grams per day (normal growth), the comparison group showed a catch-up growth of 16 gms/day, while the MPH group gained 29 gms/day in excess of expectation, almost twice the comparison group. A 100-gram weight gain cost +308 in the MPH program and +1,635 in the traditional approach. This five-fold difference was felt to be a significant deterrent to the continuing approach of admitting children to the hospital for for the workup of FTT.(ABSTRACT TRUNCATED AT 250 WORDS)     

Strategic Use of FAFSA List Information by Colleges

Students filling out the FAFSA list colleges and universities where they wish their data, sent. Until recently, colleges were provided this list, and the practice was suspended, given concerns that colleges were using the list to strategically allocate aid. Using the, 2011–2012 NPSAS, we analyze student financial aid packages to determine if list position, affects aid. We find little evidence that it does.     

Case study: use of problem-based learning to develop students' technical and professional skills

Problem-based learning (PBL) is a pedagogy that has attracted attention for many biomedical engineering curricula. The aim of the current study was to address the research question, ‘Does PBL enable students to develop desirable professional engineering skills?’ The desirable skills identified were communication, teamwork, problem solving and self-directed learning. Forty-seven students enrolled in a biomedical materials course participated in the case study. Students worked in teams to complete a series of problems throughout the semester. The results showed that students made significant improvements in their problem-solving skills, written communication and self-directed learning. Students also demonstrated an ability to work in teams and communicate orally. In conclusion, this case study provides empirical evidence of the efficacy of PBL on student learning. We discuss findings from our study and provide observations of student performance and perceptions that could be useful for faculty and researchers interested in PBL for biomedical engineering education.     

The response of higher education to older adults: A federal perspective

This article examines and describes the responses of higher education institutions in meeting the needs of older people. Specifically, the article describes the concern of the Federal Council on the Aging for increased educational offerings for older people at American universities and colleges. It provides an overview of the demographic factors creating a graying society, discusses the challenge that aging presents to higher education, and cites, with examples, steps to be taken by higher education institutions to directly or indirectly benefit older persons.     

Successful and less-successful research performance of junior faculty

In academic medical centers, there is increasing concern about the diminishing supply of clinical investigators and the amount of clinical investigation being conducted. This study developed and evaluated an instrument designed to measure characteristics of a successful researcher. All assistant professor faculty in the tenure track at this research university were sent a two-page survey. Analyses revealed that 50 percent of the items significantly discriminated successful and less-successful researchers. A factor analysis of these items produced four stable factors: research activities, mentoring, local networks, and scholarly habits. A backward stepwise discriminant analysis revealed that only two of the four factors were needed to effectively identify successful researchers. These two factors were research activities and scholarly habits. The rate of correct classification of the two-factor equation was such that 92 percent of the successful researchers were correctly identified. Testing this instrument in other academic settings would help to determine its generalizability.     

Molecule matters Dendritic architecture a clever route to monodispersed macromolecules

Dendritic macromolecules are excellent examples for macromolecules that possess well-defined branching that develops from a core to the periphery. The pseudospherical structure of dendrimers has opened up numerous possibilities for interesting applications.
