This study investigated the effect of non-traditional guided inquiry instruction on middle school students’ conceptual understandings
of lunar concepts. Multiple data sources were used to describe participants’ conceptions of lunar phases and their cause,
including drawings, interviews, and a lunar shapes card sort. The data were analyzed via a constant comparative method to
produce profiles of each participant’s conceptual understandings and nonparametric tests also were used. Results revealed
very positive performance for observable moon phases and patterns of change, as well as the cause of moon phases. Results
indicated that significantly more participants shifted from drawing nonscientific shapes on the pretest to drawing scientific
shapes on the post-test. Results for the drawings of moon phase sequences were similar in that significantly more participants
shifted from drawing alternative waxing and waning sequences on the pretest to drawing scientific sequences on the post-test.
Also, significantly more participants shifted from alternative understanding of the cause of the moon phases on the pretest
to scientific understanding on the post-test. Implications of these findings and recommendations for further research are
provided. 相似文献

The purpose of this study was to develop an instrument to assess college students’ efficacy beliefs for conceptual change and to examine the psychometric properties of the instrument. Participants were 692 students. Results of the confirmatory factor analysis supported the hypothesized single factor structure of Efficacy Beliefs for Conceptual Change Learning Questionnaire providing evidence for the construct validity. Evidence for concurrent validity also is provided. On the basis of the evidence provided in this study, the questionnaire appears to produce valid and reliable scores for college students. With the use of the questionnaire, conceptual change researchers might be able to better assess the relationship between students’ efficacy beliefs and the change in their conceptual understandings of various science concepts. 相似文献

Design education should integrate design concepts and skills with practical and theoretical knowledge through collaborative learning. Computer‐mediated communication systems used in web‐based education systems are quite appropriate for this principle by enabling global access to course material as well as allowing interaction of participants at distributed learning environments at anytime. Course design broadly requires the organization of time, space and activities considering the tools and methods used. Based on these issues, this study proposes a framework for the design of a web‐based studio course with respect to the nature of the design process. An implementation of a sample web‐based course design is included to support the idea. Considering the benefits and limitations, the nature of web‐based design courses is explored first. Then, the sociological, ideological, epistemological and pedagogical aspects of a design studio are examined within the framework of objectives (why), objects (what), methodology (how) and management (who) with special emphasis given to synchronous and asynchronous communication. 相似文献

Research Findings: The purpose of this study was to investigate the factorial structure of kindergarten children's mathematics and science process skills and the impact of children's competencies in process skills on their performance on mathematics and science achievement tests in 3rd grade. A subset of the Early Childhood Longitudinal Study–Kindergarten cohort data set (n = 8,731) was analyzed using multilevel structural equation modeling. Results demonstrated that science and mathematics process skills were highly related at the construct level but not at the indicator level, as was anticipated. Kindergarten children's competency in mathematics process skills was a strong predictor of their performance on science and mathematics achievement tests in the 3rd grade. However, children's competency in science process skills was only a significant predictor of their performance on a science achievement test in the 3rd grade. Moreover, socioeconomic status and gender were statistically significant predictors of process skills and performance on achievement tests. Practice or Policy: The findings of the present study suggest that the development of children's science and mathematics process skills should be supported utilizing integrated inquiry-based science and mathematics activities to help children recognize the connection between mathematics and science and to contribute to their science and mathematics achievement in later grades. 相似文献

This longitudinal study examined the role of metaconceptual awareness in the change and the durability of preservice teachers’ conceptual understandings over the course of several months. Sixteen preservice early childhood teachers participated in the study. Semi-structured interviews were conducted to reveal the participants’ conceptual understandings of lunar phases (pre, post, and delayed-post) and level of metaconceptual awareness (delayed-post only). Based on the change and stability in participants’ conceptual understandings from pre to post and from post to delayed-post interviews, participants’ conceptual understandings were assigned into three groups that described the profile of their long-term conceptual understandings: “decay or stability”, “continuous growth”, and “growth and stability”. The results indicated that participants in the “continuous growth” and “growth and stability” groups had significantly higher metaconceptual awareness scores than participants in the “decay or stability” group. The results provided evidence that metaconceptual awareness plays a more decisive role in the restructuring of conceptual understandings than the durability of conceptual understandings. 相似文献

This exploratory study examines the impact of a collaborative inquiry- and design-based afterschool program on urban high school students’ IT/STEM learning—using information technology (IT) within the context of science, technology, engineering, and mathematics (STEM). The study used a mixed methods design, involving 77 participants within two cohort groups, each participating in an eighteen-month intervention period. Data were collected from the pre- and post-surveys, analysis of the participants’ IT/STEM projects, external evaluation reports, and follow-up interviews. Findings indicate that the program had a significant impact on students’ technology and IT/STEM skills, frequency of technology use, and understanding of IT use in STEM-oriented fields. Some degree of impact on attitude changes toward IT/STEM and career aspirations in these fields was also in evidence. The study demonstrates that IT/STEM experiences supported through technology-enhanced, inquiry- and design-based collaborative learning strategies have significant impact on urban high school students’ IT/STEM learning. Effect of afterschool programs on attitude changes and IT/STEM-related career aspirations of urban high school students are recommended areas of further investigation. 相似文献

The purpose of this study was to examine parental priorities regarding science education in the early years. The study sample included 1456 Turkish parents of pre-K children (36–72 months). Parents were asked to prioritize eight academic content areas, including science, in descending order. The results demonstrated that the number of parents who prioritized science over other academic content areas in pre-K classrooms was quite low. Parents who ranked science highly deviated from the whole sample and almost all of these parents were identified as outliers by the two-step cluster analysis. Parents of boys and younger children and parents with high-SES level were more likely to prioritize science over other academic content areas. The findings suggest that parental preferences overall align well with early childhood teachers’ tendency to teach less science than other content areas, and parental priorities might be another major factor that contributes to limited science learning experiences in the early years. 相似文献

The purpose of this study was to describe four- to six-year-old children's understandings of the mechanism of rainfall and to reveal possible differences due to age. A total of 22 children participated in the study (mean age = 60.4 months; range 48–73 months), including 14 boys and 8 girls, all from middle-SES families. To reveal children's understanding of the mechanism of rainfall, semi-structured interviews were conducted using a set of interview questions. Children were individually interviewed, and interviews were audio-taped and transcribed. The constant comparative method was used to analyze the transcribed audio tapes. A framework of codes was developed based on previous studies of children's understanding of the mechanism of rainfall. This partial framework of codes served as the basis for describing children's conceptual understandings of the mechanism of rainfall. A nonparametric statistical test was used to test for age differences in children's conceptions of the mechanism of rainfall. The results indicated that older preschool children were more likely to have synthetic or naturalistic conceptions than the younger children. Implications of the findings for instructional practices in early childhood classrooms are discussed. 相似文献

This study explores the impacts of selected early science experiences in kindergarten (frequency and duration of teachers' teaching of science, availability of sand/water table and science areas, and children's participation in cooking and science equipment activities) on children's science achievement in kindergarten and third grade using data for 8,642 children from the Early Childhood Longitudinal Study‐Kindergarten cohort (ECLS‐K). A theoretical model that depicts the relationships between the study variables was developed and tested using structural equation modeling. Results demonstrated that availability of science materials in kindergarten classrooms facilitated teachers' teaching of science and children's participation in science activities. Likewise, the frequency and the duration of kindergarten science teaching was a significant predictor of children's science activities but not of the children's end of kindergarten science achievement scores. Children's engagement with science activities that involved using science equipment also was not a significant predictor of their end of kindergarten science achievement. However, children's participation in cooking activities was. Children's prior knowledge, motivation, socio‐economic status, and gender were all statistically significant predictors of their science achievement at the end of kindergarten and end of third grade. Results of this study indicate that early science experiences provided in kindergarten are not strong predictors of children's immediate and later science achievement. Findings of the study suggest that the limited time and nature of science instruction might be related to the limited effect of the science experiences. Implications for teacher education programs and educational policy development are discussed. © 2010 Wiley Periodicals, Inc. J Res Sci Teach 48: 217–235, 2011 相似文献
