Prevention of Substance Abuse: Can Museums Make a Difference?

After declining during the 1980s, use of alcohol, tobacco, and other drugs is again rising in junior and senior high schools nationwide. A field-trip program developed at the Hall of Health (HOH) in Berkeley, California, attempts to reverse or lessen this trend by communicating in a museum setting the dangers of drugs and addiction. Pre-visit and post-visit surveys collected from 823 students in fifth through eighth grade showed the HOH program had an immediate, significant impact on statements of intent to use alcohol, tobacco, diet pills, downers, and inhalants as well as illegal drugs in high school. Two weeks after the field trip in a follow-up study of 172 students, those who initially intended to experiment with drugs still showed a significant reduction in their original intent (as indicated in their pre-visit survey) to use 12 of 15 drugs. The program may serve as a model for museums desirous of reversing the trend toward drug use by young people.     

High school peer tutors teach MedlinePlus: a model for Hispanic outreach.

OBJECTIVES: The objective was to introduce the MedlinePlus Website to the predominantly Hispanic residents of the Lower Rio Grande Valley region of Texas by partnering with a health professions magnet high school (known as Med High). METHODS: Community assessment was used in the planning stages and included pre-project focus groups with students and teachers. Outreach methods included peer tutor selection, train-the-trainer sessions, school and community outreach, and pre- and posttests of MedlinePlus training sessions. Evaluation methods included Web statistics; end-of-project interviews; focus groups with students, faculty, and librarians; and end-of-project surveys of students and faculty. RESULTS: Four peer tutors reached more than 2,000 people during the project year. Students and faculty found MedlinePlus to be a useful resource. Faculty and librarians developed new or revised teaching methods incorporating MedlinePlus. The project enhanced the role of school librarians as agents of change at Med High. The project continues on a self-sustaining basis. CONCLUSIONS: Using peer tutors is an effective way to educate high school students about health information resources and, through the students, to reach families and community members.     

Stories of reading: Inside and outside the texts of portfolios

This essay employs Barbara Herrnstein Smith's notion of “contingencies of value,” the idea that evaluations of text vary because our readings take place in specific contexts and are shaped by cultural and historical exigencies. In this study, we apply this notion to the reading of student texts in a college composition portfolio assessment. Through an analysis of taped teacher discussions of students' writing and an examination of student responses to the grading process, we conclude that in every reading of a text (but especially in the reading of the multiple texts of a portfolio) readers posit an “implied author.” That is, based on their reading of a single text or portfolio, teacher-readers construct a persona that represents the author, and this projection can strongly influence the reader's evaluation of student work. Group discussions of portfolios allow teachers to expose and explore the value-laden nature of these judgments.     

Love is all you need: A content analysis of romantic scenes in Chinese entertainment television

A large sample of entertainment television programs that were aired on 28 channels in China in 2004 was analyzed for romantic and sexual content. Romantic scenes, typically portraying men and women already in committed relationships, appeared in 80% of the 196 programs analyzed. The analysis suggested that, according to Chinese television in the early part of the twenty-first century, emotional love was more important than physical sexual interaction in romantic relationships. More than half of the 1112 romantic scenes analyzed depicted love between the partners without any discussion or display of physical sexual behavior. Only 8% of scenes included discussion or depiction of sexual behavior (e.g., touching, kissing, and intercourse) without some sense that the partners were in a loving, committed relationship. Sexual intercourse was implied or depicted in fewer than 2% of the romantic scenes. Findings are discussed in light of the Chinese government's periodic regulation of sexually suggestive media content and attempts to filter Internet content. The extent to which such content may affect young viewers' perceptions of romantic relationships and sexual behavior is also discussed.     

Particulate representation of a chemical reaction mechanism

A growing area of interest in chemical education has been the research associated with conceptual understanding at the particulate level. This study investigated the views of 10 university chemistry lecturers, 85 pre-service chemistry teachers and 23 Secondary 3 (equivalent to Year 9) chemistry students about the particulate level of a chemical reaction, namely the heating of copper (II) carbonate. Four characteristic views were identified on the basis of their diagrammatic representations of particles. These were: (a) formation of intermediates; (b) formation of free particles (e. g., atoms or ions); (c) combination of a and b: formation of free particles (e. g., atoms or ions) first, and then intermediates; (d) no mechanism. Both the majority of the lecturers and the pre-service teachers held an identical view about the reaction mechanism, namely that the decomposition of copper (II) carbonate goes through a transition stage by forming intermediates. In contrast, even though the students were familiar with this reaction, about half of them naïvely believed that copper (II) carbonate broke up on heating and the particles recombined directly to form copper (II) oxide and carbon dioxide, the two observed products. About one-third of the students had neither any notion of how the atoms in the copper (II) carbonate lattice interacted and were rearranged in the reaction nor any concept of bond-breaking and reformation in a chemical reaction.
