Classroom environment in the implementation of an innovative curriculum project in science education
A curriculum project can be positively or negatively influenced by the environment of the classroom in which it is implemented. Analysis of the perceptions of students, teachers, and external observers has allowed us to study the influence of classroom environment in the implementation of an innovative project in science education. The main conclusions indicate that even though the global evaluation is positive, more so among teachers than among students, there are differences between the perceptions of the participants, probably due to differences in interests and needs. Moreover, in the classroom environment, the teacher and the actual dynamic and spatial organization are of great importance, and it can be difficult to maintain interest or to achieve a satisfactory evaluation on the part of those students whose academic performance is lowest. © 1998 John Wiley & Sons, Inc.

From individual longitudinal data for a full cohort of first-entering students who embarked on short programs in Spain and
were observed over a 7-year period ending in 2003, we analyze the probability that an individual will drop out, transfer,
or graduate from a university school program. The statistical analysis is carried out in a competing-risks framework. We find
that the system’s internal efficiency is low, with dropout and completion rates averaging 50 and 36%, respectively. However,
we find considerable variability in the probabilities of withdrawal, transfer, and graduation among students. In this regard,
our results show that preenrollment academic ability, age at enrollment, family characteristics, and secondary educational
experience are major influences on student progress. 相似文献

Justification and Persuasion about Cloning: Arguments in Hwang’s Paper and Journalistic Reported Versions 总被引:4,自引:4,他引:0
María Pilar Jiménez-Aleixandre Marta Federico-Agraso 《Research in Science Education》2009,39(3):331-347
We examine the argumentative structure of Hwang et al.’s (2004) paper about human somatic cell nuclear transfer (SCNT, or ‘therapeutic cloning’), contrasted with four Journalistic Reported
Versions (JRV) of it, and with students’ summaries of one JRV. As the evaluation of evidence is one of the critical features
of argumentation (Jiménez-Aleixandre 2008), the analysis focuses on the use of evidence, drawing from instruments to analyze written argumentation (Kelly et al. 2008) and from studies about the structure of empirical research reports (Swales 2001). The objectives are: 1) To examine the use of evidence and the argumentative structure of Hwang et al.’s Science, 303: 1669–1674 (2004) original paper in terms of the criteria: a) pertinence of the evidence presented to the claims; b) sufficiency of the evidence
for the purpose of supporting the claims; and c) coordination of the evidence across epistemic levels. 2) To explore how the
structure of Hwang’s paper translates into the JRV and into university students’ perceptions about the evidence supporting
the claims. The argumentative structure of Hwang’s paper is such that its apparently ostensible main claim about NT constitutes
a justification for a second claim about its therapeutic applications, for which no evidence is offered. However, this second
claim receives prominent treatment in the JRV and in the students’ summaries. Implications for promoting critical reading
in the classroom are discussed. 相似文献

Supporting Teaching and Learning Using Authentic Scientific Texts: A Rejoinder to Danielle J. Ford 总被引:1,自引:1,他引:0
Anat Yarden Hedda Falk Marta Federico-Agraso María Pilar Jiménez-Aleixandre Stephen P. Norris Linda M. Phillips 《Research in Science Education》2009,39(3):391-395
In her commentary Danielle J. Ford mainly focused on three issues that highlight the promises and challenges for the use of
Adapted Primary Literature (APL) in science curricula: the possible contribution of APL to authentic experiences in secondary
schools, implementation issues of APL including the support required for the teachers, and the possibilities to extend the
use of APL to younger and older students. In this rejoinder, we first offer some general comments on Ford’s commentary. Then
we offer more specific comments on two areas of her response, authenticity and the support for teachers. 相似文献

The aim of the present study is to elicit students’ understanding of the particulate nature of matter via a cross-age study
ranging from secondary to tertiary educational levels. A questionnaire with five-item open-ended questions was administered
to 166 students from the secondary to tertiary levels of education. In light of the findings, it can be deduced that the number
of students’ responses categorized under the “sound understanding” category for each item increased with educational level,
except for U1. Also, it can be concluded that students’ specific misconceptions decreased steadily from SHS1 to SHS3, except
for item 4, but there is surprisingly a clear increase at U1. 相似文献

The main objective of the Bologna Process is to create a “European space” for higher education that allows for comparability,
compatibility, and coherence between the existing systems of higher education across Europe. This objective is commonly known
as the European higher education area (EHEA). The creation of the EHEA is a new and specific challenge for higher education
in Europe, one that depends upon improved faculty development and training across Europe. The integration of Spain and other
European countries into European higher education more generally entails these challenges. In order for necessary changes
in faculty development and training to take place, university managers and policy makers must account for designing training
plans, as well the knowledge, attitudes and needs of faculty members. This investigation was undertaken with these themes
in mind. Conducted in Madrid, Spain, it included 257 professors from ten different schools of the Universidad Complutense
de Madrid. The aim of the investigation was to understand faculty knowledge and attitudes about changes in higher education
in Europe. Moreover, with an eye to helping faculty members cope with the change that is accompanying the creation of EHEA,
the investigators sought to understand the importance that faculty members place upon professional development and how current
approaches to professional development at the university level could be improved. The results indicate a degree of ignorance
regarding changes in European higher education as well as a feeling of resistance on the part of many faculty members. While
many faculty members consider knowledge of change processes and adaptability to be important qualities, faculty responses
also indicate a clear need for guidance if they are going to integrate new learning models and adequate coping strategies
into their work in higher education. 相似文献

Schooling and the knowledge acquired at school have been considered both a cause of loss of indigenous knowledge (because it opens pathways to the non-indigenous world and worldviews) and a potential remedy to its demise (if educational curricula is aligned with indigenous realities by giving instruction in local languages and incorporating local knowledge in school content). We test the association between academic and local environmental knowledge using data from a society of forager-horticulturalists in the Bolivian Amazon who were exposed to a partially contextualized school curriculum. We found that although schooling and academic knowledge bear a negative association with local knowledge the magnitude is low, probably because schooling was partially contextualized. Contextualized learning might help avoid that the provision of universal education comes at the cost of humanity's cultural diversity. 相似文献

A Small‐Scale Randomized Efficacy Trial of the Identity Project: Promoting Adolescents’ Ethnic–Racial Identity Exploration and Resolution 下载免费PDF全文
Adriana J. Umaña‐Taylor Sara Douglass Kimberly A. Updegraff Flavio F. Marsiglia 《Child development》2018,89(3):862-870
Adolescents’ ethnic–racial identity (ERI) formation represents an important developmental process that is associated with adjustment. The Identity Project intervention, grounded in developmental theory, was designed to engage adolescents in the ERI processes of exploration and resolution. The current small‐scale efficacy trial involved an ethnic–racially diverse sample of adolescents (N = 215; Mage = 15.02, SD = .68) from eight classrooms that were randomly assigned by classroom to the intervention or attention control group. Differences between conditions in ERI exploration at Time 2 were consistent with desired intervention effects; furthermore, higher levels of ERI exploration at Time 2 predicted increases in ERI resolution at Time 3 only for youth in the treatment condition. Findings provide preliminary evidence of program efficacy. 相似文献
