Arguments for teaching about the nature of science have been made for several decades. The most recent science education policy documents continue to assert the need for students to understand the nature of science. However, little research actually explores how students develop these understandings in the context of a specific course. We examine the growth in students' understanding about the nature of astronomy in a one‐semester college course. In addition to student work collected for 340 students in the course, we also interviewed focus students three times during the course. In this article we briefly describe class data and discuss in detail how five students developed their ideas throughout the course. In particular, we show the ways in which students respond to instruction with respect to the extent to which they (a) demand and examine evidence used for justifying claims, (b) integrate scientific and religious views, and (c) distinguish between scientific and nonscientific theories. © 2000 John Wiley & Sons, Inc.

We developed a course, as part of our institution's core program, which provides students with a foundation in academic literacy in the social sciences: how to find, read, critically assess, and communicate about social science research. It is not a research methods course; rather, it is intended to introduce students to the social sciences and be better consumers of social science research. In this article, we describe the key learning objectives of this course, the basic content areas, and some of the innovative teaching and learning strategies used in the course. We also provide empirical evidence of the effectiveness of the course in meeting its learning objectives and of student responses to the course. Finally, we discuss some of the challenges in developing interdisciplinary core courses and offer suggestions for best practices for teaching social science literacy as part of the core curriculum.  相似文献

In this paper, we describe changes in students' ideas about science classes, attitudes about science, and motivations for studying science, in a classroom designed to support projectbased science learing. Using a survey designed to provide a measure of students' attitudes towards science classes and science, we have compared students enrolled in a traditional high school biology course, with students enrolled in an integrated, project-based science course called Foundations I. Survey responses were analyzed to look at differences between and within two groups of students over the course of one school year. In general, the results of this study suggest that providing students with opportunities to collect and analyze their own data in science classes results in a change in students' ideas about science classrooms. Foundations I students' increased tendency to agree with statements about using information, drawing conclusions, and thinking about problems, implies a change in their understanding of what it means to do science in school. These students, in contrast to students in the traditional Biology course, no longer describe their science experience as one of memorization, textbook reading, and test taking. Instead they see science class as a place in which they can collect data, draw conclusions, and formulate and solve problems.  相似文献

We present a theory of learning in science based on students deriving conceptual linkages among multiple models which represent physical phenomena at different levels of abstraction. The models vary in the primitive objects and interactions they incorporate and in the reasoning processes that are used in running them. Students derive linkages among models by running a model (embodied in an interactive computer simulation) and reflecting on its emergent behaviors. The emergent properties they identify in turn become the primitive elements of the more abstract, derived model. We describe and illustrate derivational links among three models for basic electricity: a particle model, an aggregate model, and an algebraic model. We then present results of an instructional experiment in which we compared high school students who were exposed to these model derivations with those who were not. In all other respects, both groups of students received identical instruction. The results demonstrate the importance of enabling students to construct derivational linkages among models, both with respect to their understanding of circuit theory and their ability to solve qualitative and quantitative circuit problems. © 1999 John Wiley & Sons, Inc.

Recent studies question the effectiveness of a traditional university curriculum in helping students improve their critical thinking and scientific literacy. We developed an introductory, general education (gen ed) science course to overcome both deficiencies. The course, titled Foundations of Science, differs from most gen ed science offerings in that it is interdisciplinary; emphasizes the nature of science along with, rather than primarily, the findings of science; incorporates case studies, such as the vaccine-autism controversy; teaches the basics of argumentation and logical fallacies; contrasts science with pseudoscience; and addresses psychological factors that might otherwise lead students to reject scientific ideas they find uncomfortable. Using a pretest versus posttest design, we show that students who completed the experimental course significantly improved their critical-thinking skills and were more willing to engage scientific theories the general public finds controversial (e.g., evolution), while students who completed a traditional gen ed science course did not. Our results demonstrate that a gen ed science course emphasizing the process and application of science rather than just scientific facts can lead to improved critical thinking and scientific literacy.  相似文献

This paper describes the evolution of assignments in a course for students preparing to teach secondary science, mathematics, and agriculture science. We describe and analyze work done by preservice students in two different years to look for developing teacher knowledge, explicate how we have come to understand teacher knowledge as it was enacted in this particular context, and discuss how our self-study contributed to the growth of our knowledge as teacher educators.  相似文献

Abstract

We describe a successful collaboration between mathematics and psychological science faculty members to create a learning community for our students that linked sections of introductory mathematical reasoning and psychological science courses. The students in our learning community were in their second or third semester. The learning community is designed so that, throughout the semester, students regularly move across the border between the two linked disciplines by completing common assignments, including a group project. We modified our existing course topics and frameworks to be intentional about building connections between the courses.  相似文献

In this article, we explore the roles of student researchers as they have emerged over 5 years of studies on the teaching and learning of science in urban high schools. These studies incorporate sociocultural theory in an approach to research that explores the capital that urban students bring to school and situates student researchers as active participants who exercise agency by accessing and appropriating a variety of resources. We provide examples of students engaged as productive, central members of a research team and describe the roles in which they have participated, from teacher educators and science learners to curriculum developers and ethnographers. We show how the involvement of students as researchers, within these roles, allows them to produce and select artifacts and data resources for interpretation that offer unique insider perspectives on how to improve the teaching and learning of science for urban high school students. © 2005 Wiley Periodicals, Inc.

The final report of the Joint Task Force on Computing Curricula (CC2001) suggests that an updated computer science curricula must reflect the broadening nature of our discipline. Two areas that are included in the CC2001 are software engineering (SE) and human-computer interaction (HCI). While the first inclination might be to incorporate HCI concepts into a traditional SE course, we propose a different approach. This paper outlines a project-oriented HCI course in which we are able to emphasize some SE notions in the context of HCI concepts. Our course is also a maturation class for our students because they are exposed to a number of non-programming computer science activities, including project specification, software and interface design, user testing, prototyping and use of guidelines. We include an overview of course content that illustrates our approach. We also describe our coverage of specific CC2001 knowledge units and provide some feedback data for our course.  相似文献

Student engagement with science is a long-standing, central interest within science education research. In this article, we examine student engagement with science using a Bourdiusian lens, placing a particular emphasis on the notion of field. Over the course of one academic year, we collected data in an inner London secondary science classroom through lesson observations, interviews and discussion groups with students, and interviews with the teacher. We argue that applying Bourdieusian theory can help better understand differential patterns of student engagement by directing attention to the alignment between students’ habitus and capital, and the field. Student behaviours that did not meet the requirements of the wider field were not recognised and valued as constituting engagement. Even when the ‘rules of the game’ of the science classroom were understood by the students, the tensions they experienced within the field made engaging with science impossible and undesirable. We discuss how a greater focus on the field can be useful for planning future interventions aimed at making science education more equitable.  相似文献

We present results of an investigation of university students' development of mathematical models of motion in a physical science course for preservice teachers and graduate students in science and mathematics education. Although some students were familiar with the standard concepts of position, velocity, and acceleration from physics classes, most students had difficulty using these concepts to characterize actual or hypothetical motions. Furthermore, some students developed their own nonstandard method of describing accelerated motion in terms of changes in the average velocity, from the start of the motion up to a given time. This is in contrast to the physics community's use of the acceleration construct, defined in terms of changes in the instantaneous velocity, to describe such motion. Although the change in average velocity is not typically identified as an important construct in traditional physics texts, some students found it intuitively appealing, and were able to use it successfully to describe and predict motion. We conclude that by focusing on standard constructs, and ignoring possible intuitive ways that students might view motion, standard kinematics instruction may miss an opportunity to maximize student understanding. © 2007 Wiley Periodicals, Inc.

Atomic theory or the nature of matter is a principal concept in science and science education. This has, however, been complicated by the difficulty students have in learning the concept and the subsequent construction of many alternative models. To understand better the conceptual barriers to learning atomic structure, this study explores the troublesome nature of this fundamental scientific concept. In order to illustrate the distinction of student understanding by threshold barriers, this study chose three particularly high‐achieving students from an original interview sample of 20 students who were selected from an introductory college chemistry course. The pre‐course and post‐course interview responses were examined and compared in detail. This study considers the concepts of ‘probability’ and ‘energy quantization’ to both describe the structure of the threshold of understanding students’ need to negotiate in their construction of the target model of atomic structure. In this respect, this study suggests atomic structure as a possible threshold concept for further study in science. Identifying the nature and structure of the threshold of understanding confronting students, and analyzing the troublesomeness of atomic structure, provides valuable information for understanding student learning difficulties, and insight into how they may be addressed.  相似文献

A view of science as a culturally‐mediated way of thinking and knowing suggests that learning can be defined as engagement with scientific practices. How students engage in school science is influenced by whether and how students view themselves and whether or not they are the kind of person who engages in science. It is therefore crucial to understand students' identities and how they do or do not overlap with school science identities. In this paper, we describe four middle school African American girls' engagement with science. They were selected in the 7th grade because they expressed a fondness for science in school or because they had science‐related hobbies outside of school. The data were collected from the following sources: interviews of students, their parents and their teachers; observations in science classes; journal writing; and focus groups. These girls' stories provide us with a better understanding of the variety of ways girls choose to engage in science and how this engagement is shaped by their views of what kind of girl they are. © 2000 John Wiley & Sons, Inc.

This study explored third-grade elementary students' conceptions of nature of science (NOS) over the course of an entire school year as they participated in explicit-reflective science instruction. The Views of NOS-D (VNOS-D) was administered pre instruction, during mid-school year, and at the end of the school year to track growth in understanding over time. The Young Children's Views of Science was used to describe how students conversed about NOS among themselves. All science lessons were videotaped, student work collected, and a researcher log was maintained. Data were analyzed by a team of researchers who sorted the students into low-, medium-, and high-achieving levels of NOS understandings based on VNOS-D scores and classwork. Three representative students were selected as case studies to provide an in-depth picture of how instruction worked differentially and how understandings changed for the three levels of students. Three different learning trajectories were developed from the data describing the differences among understandings for the low-, medium-, and high-achieving students. The low-achieving student could discuss NOS ideas, the medium-achieving student discussed and wrote about NOS ideas, the high-achieving student discussed, wrote, and raised questions about NOS ideas.  相似文献

Abstract

This paper describes a three-year, design-based research project to redesign a year-long, project-based advanced placement environmental science course to better support student engagement and the development of environmental citizen identities. In the initial implementation, students’ increased understanding of environmental problems paradoxically led to disengagement as students felt pessimistic and powerless. We describe design cycles across three implementation years and investigate the impact of design features on engagement and identity. Curricular design features (positioning students as change agents and widening projects’ spheres of influence from local to global), alongside expansive framing for transfer, contributed to engagement and the development of practice-linked identities as environmental citizens. We discuss implications for designing courses for engagement and identification with disciplinary content.  相似文献

We have developed the Knowledge Integration Environment (KIE) to promote lifelong learning. We believe that science courses can promote lifelong learning by offering students science models that apply to problems they encounter in their everyday lives and by engaging students in personally relevant science projects where they connect science models to typical science resources such as those found on the Internet. Our instructional framework, Scaffolded Knowledge Integration (SKI), guides the design of the Knowledge Integration Environment. In this paper we describe the Knowledge Integration Environment and report results of “design experiments” carried out to guide improvement of Knowledge Integration Environment instruction as well as to help us improve our understanding of lifelong learning.  相似文献

Educational technology has attained significant importance as a mechanism for supporting experiential learning of science concepts. However, the growth of this mechanism is limited by the significant time and technical expertise needed to develop such products, particularly in specialized fields of science. We sought to test whether interactive, educational, online software modules can be developed effectively by students as a curriculum component of an advanced science course. We discuss a set of 15 such modules developed by Harvard University graduate students to demonstrate various concepts related to astronomy and physics. Their successful development of these modules demonstrates that online software tools for education and outreach on specialized topics can be produced while simultaneously fulfilling project-based learning objectives. We describe a set of technologies suitable for module development and present in detail four examples of modules developed by the students. We offer recommendations for incorporating educational software development within a graduate curriculum and conclude by discussing the relevance of this novel approach to new online learning environments like edX.  相似文献

Preservice science teachers face numerous challenges in understanding and teaching science as inquiry. Over the course of their teacher education program, they are expected to move from veteran science students with little experience learning their discipline through inquiry instruction to beginning science teachers adept at implementing inquiry in their own classrooms. In this study, we used Aikenhead’s (Sci Educ 81: 217–238, 1997, Science Educ 85:180–188, 2001) notion of border crossing to describe this transition preservice teachers must make from science student to science teacher. We examined what one cohort of eight preservice secondary science teachers said, did, and wrote as they both conducted a two-part inquiry investigation and designed an inquiry lesson plan. We conducted two types of qualitative analyses. One, we drew from Costa (Sci Educ 79: 313–333, 1995) to group our preservice teacher participants into one of four types of potential science teachers. Two, we identified successes and struggles in preservice teachers’ attempts to negotiate the cultural border between veteran student and beginning teacher. In our implications, we argue that preservice teachers could benefit from explicit opportunities to navigate the border between learning and teaching science; such opportunities could deepen their conceptions of inquiry beyond those exclusively fashioned as either student or teacher.  相似文献

Attitudes toward science are an important aspect of students’ persistence in school science and interest in pursuing future science careers, but students’ attitudes typically decline over the course of formal schooling. This study examines relationships of students’ attitudes toward science with their perceptions of science as inclusive or non-religious, and their epistemological beliefs about epistemic authority and certainty. Data were collected using an online survey system among undergraduates at a large, public US university (n = 582). Data were prepared using a Rasch rating scale model and then analyzed using multiple-regression analysis. Gender and number of science and mathematics courses were included as control variables, followed by perceptions of science, then epistemological beliefs. Findings show that respondents have more positive attitudes when they perceive science to be inclusive of women and minorities, and when they perceive science to be incompatible with religion. Respondents also have more positive attitudes toward science when they believe scientific knowledge is uncertain, and when they believe knowledge derives from authority. Interpretations of these findings and implications for future research are discussed.  相似文献
