A structural equation model of conceptual change in physics   总被引:1,自引:0,他引:1  
A model of conceptual change in physics was tested on introductory‐level, college physics students. Structural equation modeling was used to test hypothesized relationships among variables linked to conceptual change in physics including an approach goal orientation, need for cognition, motivation, and course grade. Conceptual change in physics was determined using gains from pre‐ to post‐administration of the Force Concept Inventory (FCI). Results indicated that need for cognition and approach goals had a significant influence on motivation. Motivation influenced change scores on the FCI both directly, and indirectly, through course grade. Finally, course grade directly influenced conceptual change. The implications of these findings for future research and developing students' conceptual change in physics are discussed. © 2011 Wiley Periodicals, Inc. J Res Sci Teach 48: 901–918, 2011  相似文献

What trajectories do students follow as they connect their observations of electrostatic phenomena to atomic‐level visualizations? We designed an electrostatics unit, using the knowledge integration framework to help students link observations and scientific ideas. We analyze how learners integrate ideas about charges, charged particles, energy, and observable events. We compare learning enactments in a typical school and a magnet school in the USA. We use pre‐tests, post‐tests, embedded notes, and delayed post‐tests to capture the trajectories of students’ knowledge integration. We analyze how visualizations help students grapple with abstract electrostatics concepts such as induction. We find that overall students gain more sophisticated ideas. They can interpret dynamic, interactive visualizations, and connect charge‐ and particle‐based explanations to interpret observable events. Students continue to have difficulty in applying the energy‐based explanation.  相似文献

Understanding complex conceptual relationships is crucial for Korean high school history learning. The motivating hypothesis for this study is that a Cognitive Flexibility Theory‐based Hypertext instructional module will promote acquisition of advanced knowledge associated with complex conceptual relationships. This study focussed on improving Korean history teaching and learning in terms of these learner characteristics based on Cognitive Flexibility Theory, an influential constructivist approach in the field of educational technology. A referential hypertext program based on Spiro and his colleagues’ (1988, 1990) Cognitive Flexibility Theory (CFT) was developed for this study. Three learning programs were presented: (1) Cognitive Flexibility Theory‐Based Hypertext (CFTH), (2) hierarchical hypertext, similar to CFTH except for its hierarchical node connections, and (3) a textbook representing the typical Korean high school history instruction process. The effects of these three treatments on history achievement were examined in terms of post‐test item characteristics. Independent variables were students’ IQ, and prior knowledge and motivation toward each learning program that was measured after the treatment. Students’ achievement was the highest among three groups, especially in complex items: comparison, analysis and synthesis. In the CFTH group high IQ and low PK students’ achievement was most improved, and motivation was the chief influential factor in explaining the achievement.  相似文献

The relationships among science and engineering attitude, physics conceptual understanding, and physics achievement were explored for a population of college freshman engineering students over two semesters. Gender and SAT‐Quantitative measures were included as exogenous variables in a longitudinal path analysis. Attitude was theorized to predict achievement contemporaneously and at the next time point, while conceptual understanding was theorized to predict physics achievement contemporaneously and at the next time point. Each at one time was theorized to predict scores at the next time. A sample of 200 freshman engineering students participating in an integrated curriculum were assessed in September, December, and April (with a loss of 64 students) with the Force Concepts Inventory (FCI), Mechanics Baseline Test (MBT), and a locally developed attitude measure. The observed model indicated that the FCI predicted attitude at time 1 with no other paths between them, that FCI at time 1 predicted MBT at time 1 and time 2, FCI at time 2 predicted MBT at time 3, and MBT at time 1 predicted FCI at time 2. Gender and SAT‐Quantitative scores were predictive only of FCI and MBT at time 1. Results supported an interactive model of conceptual understanding and achievement, with attitude largely irrelevant to the process for this population. © 2000 John Wiley & Sons, Inc.

Israeli junior high‐school science teachers usually have a background in biology, and their knowledge of physics is limited. We show that by improving teachers' qualitative understanding it is possible to increase their confidence and willingness to teach physics. We conducted three‐day workshops for teachers (n = 92), which were followed by ongoing activities and support. The teacher workshops were based on a new qualitative approach that we developed for studying mechanics, which has been shown to be effective with students. A study of teachers who had not participated in the workshop shows that they had the same conceptual difficulties as their students. A comparison of pre‐ and post‐workshop questionnaires indicates that the participating teachers gained self‐confidence in their ability to explain everyday phenomena, changed their views about the relevance and interest of physics to the students and were willing to implement the method in their classes.  相似文献

Information is often tabulated, both for the general public and for students in the classroom. The relative effectiveness of tabulated data and prose for making some aspects of data and co‐variation memorable was investigated. Three types of variable (categoric, discrete and continuous) and various patterns in the data were tested on 94 Year 9 students (13—14 years old). The effect of post‐questions on recall was also studied. Tabulating data was found to be generally superior to embedding it in prose as far as recall of data and co‐variation are concerned. Other factors which particularly affected recall included the pattern in the data and the ability of the student as defined by the school. The type of variable seemed to be less important for these students and the data tested. The post‐questions used here did not enhance recall of data or co‐variation. Some aspects of mental model theory were found useful in explaining the effects.  相似文献

An understanding of mechanical waves is a pre‐requisite for the study of many topics in advanced physics, and indeed in many other disciplines. There have been many research studies in mechanical waves, all of which have revealed that students have trouble with the basic concepts. Therefore, in order for teachers to prepare appropriate instruction for their classes, it is useful to diagnose their students' conceptions—if possible before they enter class. It is for this purpose that many diagnostic instruments have been developed, often in the form of multiple‐choice tests. In this study, we have used the open‐ended Wave Diagnostic Test to develop a multiple‐choice conceptual survey in an evolutionary manner. The two‐year development procedure included open‐ended surveys and interviews involving 299 Thai students and 88 Australian students. The final version, called the Mechanical Waves Conceptual Survey, has been administered to 632 Australian students from high school to second‐year university and 270 Thai high school students. Standard statistical analyses show that the survey is reliable and valid. Further validity checks, including consultation with experts, were also carried out. The survey has four subtopics—propagation, superposition, reflection, and standing waves—and the teachers can choose the subtopics relevant for their students. In this paper we also demonstrate the use of a typical survey question to test students' conceptual understanding and identify common alternative conceptions.  相似文献

This paper reports a cross‐sectional study of Taiwanese physics students’ understanding of subatomic phenomena that are explained by quantum mechanics. The study uses students’ explanations of their answers to items in a questionnaire as a proxy for students’ thinking. The variation in students’ explanations is discussed as is the development in the way in which students link different concepts. A discussion of the source of students’ ideas turns to the way schema contain mental models that derive from sensori‐experiences. The principal recommendation for teaching is the need to include practical activities on a range of precursor phenomena so as to extend the students repertoires of mental models. This advice is different from that given in previous studies.  相似文献

This paper reports an evaluation of the physics course at Dickson College (ACT) looking at students' high school experience, their expectations before beginning and their impressions and feelings during the course. In general, students seem to have a fairly negative approach to physics, enrolling for a variety of often vague utilitarian reasons but with little expectation of enjoyment or interest. These opinions were most prevalent in girls who tend to find the content difficult and the course as a whole uninteresting. There is also a significant difference between girls and boys in their response to different types of assessment items. In an attempt to enhance the level of interest and enjoyment in students we have been phasing in a more ‘conceptual’ approach to the teaching of physics.

This study explores how students' physics identities are shaped by their experiences in high school physics classes and by their career outcome expectations. The theoretical framework focuses on physics identity and includes the dimensions of student performance, competence, recognition by others, and interest. Drawing data from the Persistence Research in Science and Engineering (PRiSE) project, which surveyed college English students nationally about their backgrounds, high school science experiences, and science attitudes, the study uses multiple regression to examine the responses of 3,829 students from 34 randomly selected US colleges/universities. Confirming the salience of the identity dimension for young persons' occupational plans, the measure for students' physics identity used in this study was found to strongly predict their intended choice of a physics career. Physics identity, in turn, was found to correlate positively with a desire for an intrinsically fulfilling career and negatively with a desire for personal/family time and opportunities to work with others. Physics identity was also positively predicted by several high school physics characteristics/experiences such as a focus on conceptual understanding, real‐world/contextual connections, students answering questions or making comments, students teaching classmates, and having an encouraging teacher. Even though equally beneficial for both genders, females reported experiencing a conceptual focus and real‐world/contextual connections less frequently. The explicit discussion of under‐representation of women in science was positively related to physics identity for female students but had no impact for male students. Surprisingly, several experiences that were hypothesized to be important for females' physics identity were found to be non‐significant including having female scientist guest speakers, discussion of women scientists' work, and the frequency of group work. This study exemplifies a useful theoretical framework based on identity, which can be employed to further examine persistence in science, and illustrates possible avenues for change in high school physics teaching. © 2010 Wiley Periodicals, Inc.

Research suggests that conventional teaching techniques have proved largely ineffective for dealing with the problem of science students’ misconceptions or alternative frameworks. This paper reports an investigation whereby inter‐personal conflict within dyadic interactions is used as a strategy for promoting development towards correct scientific conceptions in specific areas of electrical circuits and mechanics amongst first‐year tertiary physics students. The data indicate that a large number of physics students at the tertiary level hold non‐scientific conceptions of these physical phenomena. The dyadic interaction strategy proved effective as a means of encouraging students to actively and closely consider their own thinking about basic physical concepts. Further, results highlight the importance of inter‐personal conflict in the process of conceptual change.  相似文献

We examine third year university physics students' use of models when explaining familiar phenomena involving interaction between metals and electromagnetic radiation. A range of scientific models are available to explain these phenomena. However, explanations of these phenomena tend not to be used as exemplars of scientific models within undergraduate physics education. The student sample is drawn from six universities in UK and Sweden. These students have difficulties in providing appropriate explanations for the phenomena. Many students draw upon the Bohr model of isolated atoms when explaining light emission of metals. The students tend not to recognize that atoms in metals interact to give an electronic structure very different from that of the isolated atom. Few students use a single model consistently in their explanations of these related phenomena. Rather, students' use of models is sensitive to the context in which each phenomenon is presented to them.  相似文献

The research issue in this study is how to structure collaborative learning so that it improves solving physics problems more than individual learning. Structured collaborative learning has been compared with individual learning environments with Schoenfeld’s problem‐solving episodes. Students took a pre‐test and a post‐test and had the opportunity to solve six physics problems. Ninety‐nine students from a secondary school in Shanghai participated in the study. Students who learnt to solve problems in collaboration and students who learnt to solve problems individually with hints improved their problem‐solving skills compared with those who learnt to solve the problems individually without hints. However, it was hard to discern an extra effect for students working collaboratively with hints—although we observed these students working in a more structured way than those in the other groups. We discuss ways to further investigate effective collaborative processes for solving physics problems.  相似文献

This article describes the results of an extensive study, which examined the interests of intermediate‐level secondary students, from the State of Hesse in the Federal Republic of Germany, in aspects of physics and technology.

Both boys and girls show greater interest in technological issues than in issues of pure physics. This distribution of interest is in contrast to the importance accorded to these subjects in school curricula. Children from rural areas seem to have a slightly better background of experiences involving knowledge of physics and technology than children from urban areas. A correlation was found to exist between out‐of‐school activities concerned with technology and the natural sciences, and academic achievement as measured by students’ physics grades. Girls display a general interest in natural phenomena which are not sufficiently covered by physics curricula.  相似文献

One way to fascinate, engage, arouse curiosity, motivate, and stimulate intellectual development in learning scientific concepts is to use counterintuitive questions. These questions make students aware of the inadequacies of their own thinking by exposing them to situations whose outcomes are inconsistent with what they would expect. In this study, a counterintuitive dynamics test (CIDT) is developed and administered to high school students along with the force concept inventory (FCI). After expert reviews, the initial version of the test consisting of 39 questions was administered to 87 students as a pilot study. After item analysis, a final version of 30 questions was developed; its internal consistency reliability coefficient was calculated as 0.826. The CIDT and FCI were administered to 229 students from 9 different high schools in Turkey. The results indicated that while in FCI students were mostly affected by everyday experiences and while in CIDT by carelessness and a superficial approach. Average scores for both tests were roughly equal and low. The results showed that the CIDT is a new test that measures another dimension of dynamic concepts and should be used along with the FCI.  相似文献

The purpose of this study was to determine if there are relationship among freshmen students' Field depended or field independent (FD/FI) cognitive style, conceptual understandings, and problem solving skills in mechanics. The sample consisted of 213 freshmen (female = 111, male = 102; age range 17–21) who were enrolled in an introductory physics course required for science education prospective teachers. Data collection was done during the fall semesters in three successive years. At the beginning of each semester the Force Concept Inventory (FCI) and the Group Embedded Figure Test (GEFT) were administered to assess students' initial understanding of basic concepts in mechanics and FD/FI tendency of students, respectively. After completion of the course, the FCI and the Mechanics Base Line Test (MBT) were administered. The results indicated that students conceptual understanding were not statistically related to their FD/FI cognitive styles for both pre and post results. However, their problem‐solving skills were statistically related to their FD/FI cognitive style. The findings of the present and previous studies are compared, and the possible effects of the present studies on previous studies on teaching, learning and assessment for introductory mechanics are discussed.  相似文献

In the past three decades in high-income countries, female students have outperformed male students in most indicators of educational attainment. However, the underrepresentation of girls and women in science courses and careers, especially in physics, computer sciences, and engineering, remains persistent. What is often neglected by the vast existing literature is the role that schools, as social institutions, play in maintaining or eliminating such gender gaps. This explorative case study research compares two high schools in Israel: one Hebrew-speaking state school that serves mostly middleclass students and exhibits a typical gender gap in physics and computer science; the other, an Arabic-speaking state school located in a Bedouin town that serves mostly students from a lower socioeconomic background. In the Arabic-speaking school over 50% of the students in the advanced physics and computer science classes are females. The study aims to explain this seemingly counterintuitive gender pattern with respect to participation in physics and computer science. A comparison of school policies regarding sorting and choice reveals that the two schools employ very different policies that might explain the different patterns of participation. The Hebrew-speaking school prioritizes self-fulfillment and “free-choice,” while in the Arabic-speaking school, staff are much more active in sorting and assigning students to different curricular programs. The qualitative analysis suggests that in the case of the Arabic-speaking school the intersection between traditional and collectivist society and neoliberal pressures in the form of raising achievement benchmarks contributes to the reversal of the gender gap in physics and computer science courses.  相似文献
