Anthropogenic climate change remains divisive in the United States, where skepticism of the scientific consensus is associated with conservative worldviews, resulting in political polarization. This study considers three hypotheses regarding U.S. polarization over climate change that have emerged from social psychology research and applies them to science education by showing how these hypotheses could relate to adolescents' science learning. We then test each hypothesis within an experimental educational intervention designed to study the influence of worldview, mechanistic knowledge, and quantitative reasoning on students' written arguments about climate change. We used mixed methods to analyze the results of this individually randomized trial with clustering involving 357 participants in grades 9–11 from 5 U.S. sites. Findings show that: (a) exposure to mechanistic knowledge about climate change increased odds of receptivity toward climate change; (b) increasingly conservative worldviews were associated with decreased odds of receptivity; (c) worldview and quantitative reasoning interacted, resulting in an amplified effect of worldview for students with greater quantitative reasoning. Results also suggest that the influence of worldview and mechanistic knowledge on receptivity work independently from one another in our dataset. This study demonstrates the value of teaching mechanistic understandings of climate change, yet also demonstrates the influence of worldview on receptivity to climate change for adolescents, as well as complex interactions between quantitative reasoning (something school science aims to develop) and worldview. It shows that moving the U.S. public toward the scientific consensus is complex and involves confronting ideologically motivated reasoning within science education. 相似文献

The theories of Jean Piaget and William Perry provide two different theories of intellectual development with several similiarities, but also with critical differences. In this study a comparison was made to determine whether the two theories describe operation of the same mental structures or two fundamentally different aspects of intellectual development. The results, based upon individual interviews of all participants, indicate that the two theories outline different and independent processes for assessing intellectual development. 相似文献

A social constructivist assessment process model: how the research literature shows us this could be best practice 总被引:2,自引:2,他引:2

Although assessment is acknowledged as vitally important in its effect on students’ approaches to learning, there is much criticism of assessment practice. This paper argues that if a social constructivist approach is applied to the assessment process many of the problems could be overcome. It describes what a social constructivist approach to assessment would look like and gives practical examples, from the research literature, of ways it could be implemented. 相似文献

It is clear from the literature that feedback is potentially the most powerful and potent part of the assessment cycle when it comes to improving further student learning. However, for some time, there has been a growing amount of research evidence that much feedback practice does not fulfil this potential to influence future student learning because it fails in a host of different ways. This dilemma of the disjuncture between theory and practice has been increasingly highlighted by the UK National Student Survey results. This paper uses a model of the assessment process cycle to frame understandings drawn from the literature, and argues that the problem with much current practice resides largely in a failure to effectively engage students with feedback. The paper goes on to explore how best to effectively engage students with assessment feedback, with evidenced examples of feedback strategies that have successfully overcome this problem. 相似文献

Blood and Bones: The Influence of the Mass Media on Australian Primary School Children’s Understandings of Genes and DNA 总被引:1,自引:0,他引:1
Previous research showed that primary school children held several misconceptions about genetics of concern for their future lives. Included were beliefs that genes and DNA are separate substances, with genes causing family resemblance and DNA identifying suspects at crime scenes. Responses to this work ‘blamed’ the mass media for these misunderstandings. This study aimed to determine whether that blame had any foundation by examining the media habits and conceptions about genes and DNA of Australian children. With little prior research considering the influence of entertainment mass media on children’s academically relevant knowledge, this was an exploratory study with a mixed modes design. Data were collected by detailed media questionnaires and face-to-face interviews with 62 children aged 10–12 years, and subjected to content and thematic analysis. Specific mass media examples children reported using were examined for genetics content. Results indicate 5 h/day of media use, mostly television including crime shows, and that children perceived television to be their main source of information about genetics. Most children (89 %) knew DNA, 60 % knew genes, and more was known about uses of DNA outside the body such as crime solving or resolving family relationships than about its biological nature and function. Half believed DNA is only in blood and body parts used for forensics. These concepts paralleled the themes emerging from the media examples. The results indicate that the mass media is a pervasive teacher of children, and that fundamental concepts could be introduced earlier in schools to establish scientific concepts before misconceptions arise. 相似文献

We used Signal Detection methodology to examine how cognitiveset affects mothers' response to an infant cry. We asked whether a cry from a "difficult" versus an "easy" infant would elicit a change in sensitivity or response bias in mother processing of these cries. Thirty-eight mothers of 4- to 6-month-old infants participated in a Signal Detection task in which they were asked whether they could detect differences between a standard cry and 1 to 4 cry variants. Cry variants differed from the standard cry in small, systematic changes in fundamental frequency. The task was conducted in 2 parts; each part constituted a condition wherein mother received a cognitive set manipulation that labeled the identical cry as coming from either a'difficult'or an "easy" infant. An increase in mothers' sensitivity was associated with the "difficult" infant cognitive set. We examined as well how a coping strategy(illusion of control) affected cry signal processing. Mothers who Exhibited high illusory control were least -sensitive in detecting differences between cries. Two information-prcessing, measures response time and heart rate, were also collected and showed that greater sensitivity was associated with more efficient processing of the cry signal. 相似文献

In order to develop more effective ways of helping adolescents and young adult (AYA) cancer survivors cope with cancer-related uncertainty, it is important to understand how AYAs respond communicatively to each other's uncertainty. We designed this project to gain insight into the patterns of social support that occur in response to AYAs' expressions of uncertainty. We analyzed 510 responses to posts in an AYA-focused online discussion group. Eighty-two percent of messages responding to uncertainty contained informational support. Sixty-seven percent contained multiple types of support. Among medical, personal, and social sources of uncertainty, the most typical response tended to be a combination of informational support accompanied by emotional and/or esteem support. AYAs who express uncertainty in online support groups should be advised that their posts are likely to be met with information, such as advice and referrals, which may either facilitate or impede their uncertainty management goals. 相似文献

ABSTRACT In this brief response to Richard A. Danner's “Skating with Donovan: Thoughts on Librarianship as a Profession,” the author finds new reasons to doubt the merits of a “weak” model of librarianship that overemphasizes user demands at the expense of professional ethical commitments to collect, organize, and preserve. 相似文献
