Just do it? impact of a science apprenticeship program on high school students' understandings of the nature of science and scientific inquiry

The purpose of this study was to explicate the impact of an 8‐week science apprenticeship program on a group of high‐ability secondary students' understandings of the nature of science and scientific inquiry. Ten volunteers (Grades 10–11) completed a modified version of the Views of Nature of Science, Form B both before and after their apprenticeship to assess their conceptions of key aspects of the nature of science and scientific inquiry. Semistructured exit interviews provided an opportunity for students to describe the nature of their apprenticeship experiences and elaborate on their written questionnaire responses. Semistructured exit interviews were also conducted with the scientists who served as mentors for each of the science apprentices. For the most part, students held conceptions about the nature of science and scientific inquiry that were inconsistent with those described in current reforms. Participating science mentors held strong convictions that their apprentices had learned much about the scientific enterprise in the course of doing the science in their apprenticeship. Although most students did appear to gain knowledge about the processes of scientific inquiry, their conceptions about key aspects of the nature of science remained virtually unchanged. Epistemic demand and reflection appeared to be crucial components in the single case where a participant experienced substantial gains in her understandings of the nature of science and inquiry. © 2003 Wiley Periodicals, Inc.

Expression of a taste aversion conditioned with an odor-taste compound: Overshadowing is relatively weak in weanlings and decreases over a retention interval in adults

Adult rats were injected with lithium chloride (LiCl) after consumption of a novel flavor (chocolate milk) that either was or was not presented together with a novel ambient odor (banana) as a compound conditioned stimulus (CS). In Experiment 1, the adults’ consumption of the flavor 24 h after conditioning was compared with that of weanling rats given the same conditioning treatment on Postnatal Day 21. The results confirmed previous indications that the reduction in aversion observed for adults conditioned with the compound CS (overshadowing) was weak or nonexistent in weanlings. After a longer retention interval (21 days), there was no evidence of overshadowing in adults despite maintained retention of the basic conditioned aversion. In Experiment 2 this decrease in overshadowing after a long retention interval was replicated with adult animals and extended to a different method of testing. The form of the effect was the same as in Experiment 1: The decrease in overshadowing occurred over the retention interval without loss in retention of the basic taste aversion; the decrease in overshadowing was a consequence of anincrease in the flavor aversion displayed by animals conditioned with the compound CS. The impaired flavor aversion (i.e., the overshadowing) observed shortly after conditioning apparently was due to factors associated with memory retrieval, rather than to reduced attentional or associative strength.     

“I’m Demi and I Have Bipolar Disorder”: Effect of Parasocial Contact on Reducing Stigma Toward People With Bipolar Disorder

Examining celebrity influence, participants (N = 594) completed an experiment to see if negative stereotypes toward bipolar disorder could be reduced as a function of mode of disease disclosure from a celebrity (Demi Lovato) diagnosed with the condition. Respondents were randomly assigned to view one of three conditions where the celebrity discusses her battle with bipolar disorder (or a comparison message). Measures assessing parasocial relationship (PSR), level of parasocial interaction (PSI), transportation, social distance towards, and negative stereotypes about people with bipolar disorder were used. Social distance and negative stereotypes toward people with bipolar disorder reduced significantly following exposure to Demi Lovato’s disclosure about the disease via either TV/magazine interview. Implications of results for how celebrity disease disclosures may help reduce stigma toward bipolar condition are discussed.     

A study of changes in middle school teachers' understanding of selected ideas in science as a function of an in-service program focusing on student preconceptions

This article examines the impact of a specially designed in-service model on teacher understanding of selected science concepts. The underlying idea of the model is to get teachers to restructure their own understanding of a selected science topic by having them study the structure and evolution of their students' ideas on the same topic. Concepts on topics from the life, earth, and physical sciences served as the content focus and middle school Grades 4–9 served as the context for this study. The in-service experience constituting the main treatment in the study occurred in three distinct phases. In the initial phase, participating teachers interviewed several of their own students to find out what kinds of preconceptions students had about a particular topic. The teachers used concept mapping strategies learned in the in-service to facilitate the interviews. Next the teachers teamed with other teachers with similar topic interests and a science expert to evaluate and explore the scientific merit of the student conceptual frameworks and to develop instructional units, including a summative assessment during a summer workshop. Finally, the student ideas were further evaluated and explored as the teachers taught the topics in their classrooms during the fall term. Concept maps were used to study changes in teacher understanding across the phases of the in-service in a repeated-measures design. Analysis of the maps showed significant growth in the number of valid propositions expressed by teachers between the initial and final mappings in all topic groups. But in half of the groups, this long-term growth was interrupted by a noticeable decline in the number of valid propositions expressed. In addition, analysis of individual teacher maps showed distinctive patterns of initial invalid conceptions being replaced by new invalid conceptions in later mappings. The combination of net growth of valid propositions and the patterns of evolving invalid conceptions is discussed in constructivist terms.
