Developing the changes in attitude about the relevance of science (CARS) questionnaire and assessing two high school science classes 总被引：1，自引：0，他引：1
This study has two purposes: (a) methodological—to design and test a new instrument able to reflect changes in attitudes toward science over time, and (b) investigative—to find out the effect of two similar curricular treatments on the attitudes of two classes. Items about the relevance of science to students' lives were developed, pilot‐tested, and analyzed using Rasch modeling. We then divided reliable items into three equivalent questionnaire forms. The final three forms of the questionnaire were used to assess high school students' attitudes. Over 18 weeks, one class used a core curriculum (Science and Sustainability) to learn science in the context of making decisions about societal issues. A second class used the same core curriculum, but with parts replaced by computer‐based activities (Convince Me) designed to enhance the coherence of students' arguments. Using traditional and Rasch modeling techniques, we assessed the degrees to which such instructional activities promoted students' beliefs that science is relevant to them. Both classes tended to agree more, over time, that science is relevant to their lives, and the increases were statistically equivalent between classes. This study suggests that, by using innovative, issue‐based activities, it is possible to enhance students' attitudes about the relevance of science. © 2003 Wiley Periodicals, Inc.

The benefits of international education experiences for students are well documented. The effect on the individual of international experiences has been researched and theorised by authors for at least the last 20 years. In this paper the experiences of three academics who accompanied pre-service teachers on a 3 week international practicum are examined through the prism of intercultural confidence and competence. Accompanying academic Juliet reflects on dealing with the added difficulties the pre-service teachers encountered as a result of their inexperience in classroom settings. Accompanying academic Paula reflects on the challenges of “teaching-out-of-field.” Accompanying academic Sue reflects on the social and transitional challenges experienced when supporting pre-service teachers who collectively had issues related to health, safety, and interpersonal relationships. These lived experiences provide a richer understanding of the role of international partnerships in contributing to academic growth and increasing intercultural competency in tandem with their students. 相似文献

Using a framework of assessment literacy that included principles, tools, and purposes, this study explored the assessment literacy of 11 secondary preservice teachers. Participants?? journals, teaching philosophies, and inquiry-based science units served as data sources. We examined how the preservice teachers understood assessment tools as well as their reasons for using assessment. Additionally, we investigated how the preservice teachers incorporated assessments into inquiry-based science units. Analysis of these documents indicated that preservice teachers recognize the need to align assessments with learning goals and instructional strategies and are using a variety of assessments. They understood several ways to use assessment for learning. However, the inclusion of assessments contained within the science units did not fully align with the views of assessment the preservice teachers presented in their teaching philosophies or journals. Instead of using a variety of assessments that reflect science reforms, the preservice teachers reverted to traditional forms of assessment in their science units. Teacher education programs need to place more emphasis on developing preservice teachers?? assessment literacy so that they are better able to select and implement a variety of appropriate assessments to foster student learning. 相似文献

As biotechnology‐related scientific advances, such as stem cell research (SCR), are increasingly permeating the popular media, it has become ever more important to understand students’ ideas about this issue. Very few studies have investigated learners’ ideas about biotechnology. Our study was designed to understand the types of alternative conceptions students hold concerning SCR. The qualitative research design allowed us to examine college students’ understandings about stem cells and SCR. More specifically, we addressed the following questions: How can alternative conceptions about stem cell topics be categorized? What types of alternative conceptions are most common? Participants included 132 students enrolled in a biotechnology course that focused on the scientific background of biotechnology applications relevant to citizens. In this study, we used an inductive approach to develop a taxonomy of alternative ideas about SCR by analyzing student responses to multiple open‐ended data sources. We identified five categories of conceptions: alternative conceptions about what, alternative conceptions about how, alternative conceptions about medical potential, terminology confusion, and political and legal alternative conceptions. In order to improve instruction, it is important to understand students’ ideas when entering the classroom. Our findings highlight a need to teach how science can be applied to societal issues and improve science literacy and citizenship. 相似文献

This study has explored the parents’ regulation strategies that were more likely to support children’s self-regulation in
learning situations with computers. These strategies have been analysed by means of new grids involving seven categories of
behaviour: cognitive strategies relating to identification of objective, exploration of means, attention and evaluation; motivational
strategies; and socio-communicative strategies such as joint attention and request. 62 7-year-old children from Quebec families
were examined with their mothers and fathers. The children were asked to complete two learning tasks that involved using LOGO
software to draw a picture. Results indicated that parents’ regulation varied depending on their gender; a higher directivity
was observed in mothers, more specifically through some specific strategies. Analysis of variance on repeated measures showed
that, during the session, there was a decrease in the specification of the objective, the initiation of joint attention and
of behaviour regulation in parents; and an improvement of the identification of the objective, planning and self-evaluation
in children. Correlations between parental regulation and children’s self-regulation strategies indicated positive links concerning
strategies relating to joint attention and to motivation; and negative links concerning strategies relating to the exploration
of means and evaluation. A good adjustment of the parents’ regulation and the children’s self-regulation correlated positivel
with success in the task. Methodological implications are proposed for research and psycho-educative intervention. 相似文献

Identifying students’ conceptual scientific understanding is difficult if the appropriate tools are not available for educators. Concept inventories have become a popular tool to assess student understanding; however, traditionally, they are multiple choice tests. International science education standard documents advocate that assessments should be reform based, contain diverse question types, and should align with instructional approaches. To date, no instrument of this type targeting student conceptions in biotechnology has been developed. We report here the development, testing, and validation of a 35-item Biotechnology Instrument for Knowledge Elicitation (BIKE) that includes a mix of question types. The BIKE was designed to elicit student thinking and a variety of conceptual understandings, as opposed to testing closed-ended responses. The design phase contained nine steps including a literature search for content, student interviews, a pilot test, as well as expert review. Data from 175 students over two semesters, including 16 student interviews and six expert reviewers (professors from six different institutions), were used to validate the instrument. Cronbach’s alpha on the pre/posttest was 0.664 and 0.668, respectively, indicating the BIKE has internal consistency. Cohen’s kappa for inter-rater reliability among the 6,525 total items was 0.684 indicating substantial agreement among scorers. Item analysis demonstrated that the items were challenging, there was discrimination among the individual items, and there was alignment with research-based design principles for construct validity. This study provides a reliable and valid conceptual understanding instrument in the understudied area of biotechnology. 相似文献

Given the challenging in- and out-of-school outcomes that some boys and young men of color exhibit, researchers, policymakers, and practitioners have advocated for increasing the number of Black male teachers. This strategy is predicated on the belief that having same-race and same-gender teachers can improve student learning. Drawing on Shedd’s Universal Carceral Apparatus and Brown’s Pedagogical Kind, this study used the qualitative method, specifically phenomenology, to explore the school-based experiences of 27 Black male teachers across 14 schools in one urban school district. Participants perceived that their peers and school administrators positioned them to serve primarily as disciplinarians first and teachers second. The Black male teachers described how their colleagues expected them to redirect student misbehavior. They rejected the idea that they were magically constructed or that students who were deemed as misbehaving responded to the teachers’ redirection simply because they were Black men. Instead, participants described how they attended to students’ social and emotional development, thereby influencing their capacity to engage and manage perceived misbehavior. Implications for future research are presented at the conclusion of the study. 相似文献
