Nowadays, early science education is well-accepted by researchers, education professionals and policy makers. Overall, teachers’ attitudes and conceptions toward the science subject domain and science education influence their ways of teaching and engagement. However, there is a lack of research regarding factors that affect this engagement in pre-school years. The main assumption of this study is that teachers’ attitudes regarding science in pre-school can shape children's engagement in science and develop their scientific curiosity. Therefore, the main objectives of this study are to investigate the attitudes of pre-school teachers toward engaging in science and to explore their views about the nature of curiosity: who is a curious child and how can a child's natural curiosity be fostered? An extensive survey was conducted among 146 pre-school teachers by employing both qualitative and quantitative approaches. Results indicate that most of the participants believe that scientific education should begin in early childhood; very young children can investigate and take part in a process of inquiry; and scientific activities in pre-school can influence children's long-term attitudes toward science. Despite these views, most participants felt they did not possess sufficient scientific knowledge. Furthermore, participants expressed diverse opinions when asked to identify what constitutes curiosity, how the curious child can be identified and how a child's curiosity can be fostered. The research findings carry significant implications regarding how to implement scientific activities in pre-school, and how to encourage pre-school teachers to engage children in scientific activities in a way that will nurture their natural curiosity. 相似文献

This paper describes the unique challenges that students with learning disabilities (LD) experience in science studies and addresses the question of the extent to which science teachers are willing and prepared to teach in inclusive classrooms. We employed the theory of planned behavior (TPB), according to which behavioral intentions are a function of individuals’ attitudes toward the behavior, their subjective norms, and their perceived control—i.e., their perception of the simplicity and benefits of performing the behavior. The study comprised 215 junior high school science teachers, who answered a TPB-based quantitative questionnaire. Semi-structured interviews were conducted to support and enrich the findings and conclusions. We found that teachers held positive attitudes and were willing to adapt their teaching methods (perceived control), which correlated and contributed to their behavioral intention. In terms of subjective norms, however, they felt a lack of support and ongoing guidance in providing the appropriate pedagogy to meet the needs of students with LD. We therefore recommend that educational policy makers and school management devote attention and resources to providing professional training and appropriate instructional materials and to establishing frameworks for meaningful cooperation between the science teachers and special education staff. This could ensure the efficient cooperation and coordination of all the involved parties and send a positive message of support to the science teachers who are the actual implementers of change.

This study offers an innovative and sustainable instructional model for an introductory undergraduate course. The model was gradually implemented during 3 yr in a research university in a large-lecture biology course that enrolled biology majors and nonmajors. It gives priority to sources not used enough to enhance active learning in higher education: technology and the students themselves. Most of the lectures were replaced with continuous individual learning and 1-mo group learning of one topic, both supported by an interactive online tutorial. Assessment included open-ended complex questions requiring higher-order thinking skills that were added to the traditional multiple-choice (MC) exam. Analysis of students’ outcomes indicates no significant difference among the three intervention versions in the MC questions of the exam, while students who took part in active-learning groups at the advanced version of the model had significantly higher scores in the more demanding open-ended questions compared with their counterparts. We believe that social-constructivist learning of one topic during 1 mo has significantly contributed to student deep learning across topics. It developed a biological discourse, which is more typical to advanced stages of learning biology, and changed the image of instructors from “knowledge transmitters” to “role model scientists.” 相似文献

ABSTRACTInstructional approaches in higher education that foster learning based on internal values are required with the enrollment of wider and more diverse audiences. The current study explores this challenge with a focus on the relationship between students’ learning cultures and the way instructors’ view them. We interviewed 76 students and six instructors at an established academic institution. Data comprised of 210 students’ and 146 instructors’ utterances that were analyzed using mixed methods. Findings revealed a mismatch of instructors’ conceptions about the learning culture of the typical student, potentially leading to compromises in their teaching practices. We provide evidence that reciprocal relations exist between cultures of teaching and learning, contributing to the wicked challenges of rethinking the role of teachers in reinforcing passive learning cultures in undergraduate education. Adoption of internal-based values teaching approaches can help break this feedback loop. 相似文献

This study explores the impact of ‘Scientific Communication’ (SC) skills instruction on students’ performances in scientific
literacy assessment tasks. We present a general model for skills instruction, characterized by explicit and spiral instruction,
integration into content learning, practice in several scientific topics, and application of performance tasks. The model
was applied through an instructional program that focuses on the following learning skills: information retrieval, scientific
reading and writing, listening and observing, data representation, and knowledge presentation. Throughout the 7th–8th grades,
160 students learned the whole program or one of its components: structured instruction (SI) of SC skills, or performance tasks (PT). A comparison group of 42 students did not receive instruction of SC skills. Students’ performances were assessed through
a questionnaire and a complex task that measured students’ scientific content knowledge, SC skills, and the quality of the
final products. Results indicated that students who learned the whole program or one of its components achieved higher scores
in all categories than the comparison group students. High achievers can benefit from just one component of the program: either
structured instruction (SI) or learning from practice (PT). However, they can hardly acquire SC skills spontaneously. Low
and average achievers require both components of the SC program to improve their performances. Results show that without planned
intervention, the spontaneous attainment of SC skills occurs only to a limited extent. Systematic teaching of skills can make
a significant difference. The explicit instruction of skills integrated into scientific topics, the opportunities to implement
the skills in different contexts, the role of performance tasks as ‘assessment for learning’—all these features are important
and necessary for improving students’ scientific literacy. Our general model of skills instruction can be applied to the instruction
of other high-order skills. Its application can lead to the realization of the central goal of science education: literate
students possessing scientific knowledge. 相似文献

The main objective of the study reported was to explore the effect on young children’s critical thinking of a peer-tutoring
training embedded with the metacognitive processes required for problem-based learning and, consequently, for critical thinking.
The sample consisted of 90 first- and third-grade pupils (45 pairs) randomly assigned to the experimental or control group.
The experimental tutors received the Peer Mediation training, an intervention containing embedded metacognitive processes.
The control children received a general preparation for peer-assisted learning. Following their respective preparations, all
the children participated in a peer-tutoring condition, videotaped for 25 min and subsequently analyzed with an adaptation
of the Newman et al. (Interpers Comput Technol 3(2):56–77, 1995) content analysis instrument. Analysis of the discourse conducted
during the tutoring session indicated that the tutors and tutees in the experimental groups exhibited greater depth of critical
thinking, demonstrated in the higher Quality of Discourse Ratio calculated, than did the tutors and tutees in the control
group. The findings supported previous results showing the efficacy of the Peer Mediation for Young Children mediation-training program, with its embedded metacognitive competencies, for reinforcing young children’s higher-order thinking.
Implications for educators are discussed. 相似文献

This paper describes a general model for skills instruction and its implementation through the program “Scientific Communication” for acquiring learning skills. The model is characterized by modularity, explicit instruction, spiral integration into contents, practice in various contexts, and implementation in performance tasks. It requires flexible planning and implementation by the teachers. The study investigated how science teachers implemented this model for a two-year period. Results show that they coped with this task by customizing the program; they underwent a positive change in perceptions about skills instruction, instructional models, using instructional materials, influence and involvement in school and beyond. 相似文献
