在学生经历科学探究过程的基础上,引导他们对探究活动本身做适宜的反思和认知,对他们掌握探究方法和提升探究能力是有益的。问题的关键在于我们怎样理解“过程与方法”的教学目标和采取怎样的教学策略给予实施。一、正确领会科学方法教育的目标本质学习者对方法学习的最终目的是掌握和运用,是转化为学习者相应的能力（也有人称作“过程技能”）。小学科学探究方法的教学应当有别于科学知识教学,其主要目的在于使学生获得更明确的探究方法的指导,从而更好地生成开展探究活动的能力或技能,而不是让学生条条杠杠地记住这些方法是什么或怎么样。 相似文献

In order for students to truly understand science, we feel that they must be familiar with select subject matter and also understand how that subject matter knowledge was generated and justified through the process of inquiry. Here we describe a high school biology curriculum designed to give students opportunities to learn about genetic inquiry in part by providing them with authentic experiences doing inquiry in the discipline. Since a primary goal of practicing scientists is to construct explanatory models to account for natural phenomena, involving students in the construction of their own explanatory models provides a major emphasis in the classroom. The students work in groups structured like scientific communities to build, revise, and defend explanatory models for inheritance phenomena. The overall instructional goals include helping students understand the iterative nature of scientific inquiry, the tentativeness of specific knowledge claims (and why they should be considered tentative), and the degree to which scientists rely on empirical data as well as broader conceptual and metaphysical commitments to assess models and to direct future inquiries. 相似文献

The Biology Workbench (BW) is a web‐based tool enabling scientists to search a wide array of protein and nucleic acid sequence databases with integrated access to a variety of analysis and modeling tools. The present study examined the development of this scientific tool and its consequent adoption into the context of high school science teaching in the form of the Biology Student Workbench (BSW). Participants included scientists, programmers, science educators, and science teachers who played key roles along the pathway of the design and development of BW, and/or the adaptation and implementation of BSW in high school science classrooms. Participants also included four teachers who, with their students, continue to use BSW. Data sources included interviews, classroom observations, and relevant artifacts. Contrary to what often is advocated as a major benefit accruing from the integration of authentic scientific tools into precollege science teaching, classroom enactments of BSW lacked elements of inquiry and were teacher‐centered with prescribed convergent activities. Students mostly were preoccupied with following instructions and a focus on science content. The desired and actual realizations of BSW fell on two extremes that reflected the disparity between scientists' and educators' views on science, inquiry science teaching, and the related roles of technological tools. Research on large‐scale adoptions of technological tools into precollege science classrooms needs to expand beyond its current focus on teacher knowledge, skills, beliefs, and practices to examine the role of the scientists, researchers, and teacher educators who often are involved in such adoptions. © 2010 Wiley Periodicals, Inc.

The ‘community of inquiry’ as formulated by C. S. Peirce is grounded in the notion of communities of discipline‐based inquiry engaged in the construction of knowledge. The phrase ‘transforming the classroom into a community of inquiry’ is commonly understood as a pedagogical activity with a philosophical focus to guide classroom discussion. But it has a broader application. Integral to the method of the community of inquiry is the ability of the classroom teacher to actively engage in the theories and practices of discipline‐based communities of inquiry so as to become informed by the norms of the disciplines, not only to aspire to competence within the disciplines, but also to develop habits of self‐correction for reconstructing those same norms when faced with novel problems and solutions, including those in the classroom. This has implications for science education and the role of educational philosophy in developing students' ability to think scientifically. But it also has broader implications for thinking critically within all key learning areas. Here we concentrate on science education. We present the parallels between philosophical inquiry and scientific inquiry that need to be realised to promote and engage with scientific inquiry in the classroom. We also discuss the conflicts between philosophical inquiry and the way inquiry science in the classroom is portrayed in the education literature. Based on philosophical and historical perceptions of science as inquiry, a practical approach to implementation of scientific inquiry in the science classroom is presented. 相似文献

后现代真理观强调科学的主观性,其积极意义是把科学研究看成永不停止的探究过程,科学知识是暂时的和可变的,这有利于培养学生的质疑和创新精神,但其负面影响是科学探究的放任,忽视有条理的探究。对待后现代真理观的理性态度应是兼容并蓄,辩证扬弃。 相似文献

Although the effects of open inquiry vs. more didactic approaches have been studied extensively, the effects of different types of inquiry have not received as much attention. We examined the effects of guided vs. structured inquiry on secondary students' learning of science. Students from three schools in north-eastern Thailand participated (N?=?239, Grades 7 and 10). Two classes in each school were randomly assigned to either the guided or the structured-inquiry condition. Students had a total of 14–15 hours of instructions in each condition. The dependent measures were science content knowledge, science process skills, scientific attitudes, and self-perceived stress. In comparison to the structured-inquiry condition, students in the guided-inquiry condition showed greater improvement in both science content knowledge and science process skills. For scientific attitudes and stress, students in one school benefited from guided inquiry much more than they did from structured inquiry. Findings were explained in terms of differences in the degree to which students engaged effortfully with the teaching material. 相似文献

In order to promote scientific inquiry in secondary schooling in Taiwan, the study developed a computer-based inquiry curriculum (including structured and guided inquiry units) and investigated how the curriculum influenced students’ science learning. The curriculum was implemented in 5 junior secondary schools in the context of a weeklong summer science course with 117 students. We first used a multi-level assessment approach to evaluate the students’ learning outcomes with the curriculum. Then, a path analysis approach was adopted for investigating at different assessment levels how the curriculum as a whole and how different types of inquiry units affected the students’ development of conceptual understandings and inquiry abilities. The results showed that the curriculum was effective in enhancing the students’ conceptual knowledge and inquiry abilities in the contexts of the six scientific topics. After the curriculum, they were able to construct interconnected scientific knowledge. The path diagrams suggested that, due to different instructional designs, the structured and guided inquiry units appeared to support the students’ learning of the topics in different ways. More importantly, they demonstrated graphically how the learning of content knowledge and inquiry ability mutually influenced one another and were reciprocally developed in a computer-based inquiry learning environment. 相似文献

Air Toxics Under the Big Sky is an environmental science outreach/education program that incorporates the Next Generation Science Standards (NGSS) 8 Practices with the goal of promoting knowledge and understanding of authentic scientific research in high school classrooms through air quality research. This research explored: (1) how the program affects student understanding of scientific inquiry and research and (2) how the open-inquiry learning opportunities provided by the program increase student interest in science as a career path. Treatment students received instruction related to air pollution (airborne particulate matter), associated health concerns, and training on how to operate air quality testing equipment. They then participated in a yearlong scientific research project in which they developed and tested hypotheses through research of their own design regarding the sources and concentrations of air pollution in their homes and communities. Results from an external evaluation revealed that treatment students developed a deeper understanding of scientific research than did comparison students, as measured by their ability to generate good hypotheses and research designs, and equally expressed an increased interest in pursuing a career in science. These results emphasize the value of and need for authentic science learning opportunities in the modern science classroom. 相似文献
