Students at all ages hold a wide variety of scientifically faulty knowledge structures called “misconceptions”. As far as
misconceptions in chemistry are concerned, college science students are no exception. Systematic administration to freshman
biology majors of specially-designed mid-term and term higher-order cognitive skills (HOCS)-oriented examinations within the
courses “General and Inorganic Chemistry” and “Introduction to Modern Organic Chemistry” proved these examinations to be very
effective in revealing and distinguishing between students'misconceptions, misunderstandings, and“no conceptions”. Several of these have never been mentioned before in the relevant research literature. Accordingly, reflective teaching
strategies to overcome this “misconceptions problem” and affect meaningfully subsequent learning have been explored and implemented
within our longitudinal effort to develop students' HOCS. The study results combined with accumulated experience indicate
that properly designed HOCS-oriented examinations may be very effective for revealing, but notper se for overcoming, students' misconceptions. However, within HOCS-oriented chemistry teaching, the assessment of students by
such examinations is very useful particularly for providing data for remediation purposes via appropriate modification of
the teaching strategies. Eventually, this leads to gains in students' HOCS which is in line with the overall goal of the current
reform in science education. 相似文献

Colleges of Business (COBs) have experienced high growth rates in the past decade and many colleges are imposing minimum grade point average (GPA) requirements for students to enter or remain in the college. A primary reason for this requirement may be the belief that students with high GPAs are more inclined to demonstrate higher‐order cognitive skills (HOCS) than students with low GPAs. It is not clear whether the link is valid. This study hypothesizes that students with high GPAs who are taught in the same way as students with lower GPAs will have higher perceptions of improved HOCS. We conducted an experiment in which students, with varying GPAs, at three large universities primarily used multimedia instructional materials. We obtained the students' perceptions of their improved HOCS from their responses to a survey. A regression analysis of the data reveals that the relationship between GPAs and students' perceived improvement in HOCS is significant (p < .001). We conclude the study by recommending that (a) it is critical to use research methodologies to evaluate perceived and actual learning improvements, (b) COB policies to implement GPA restrictions on admission are worthwhile, and (c) case studies need to be used much more frequently in undergraduate COB classes. 相似文献

An element of current reform in science education worldwide is the shift from the dominant traditional algorithmic lower-order
cognitive skills (LOCS) teaching, to the higher-order cognitive skills (HOCS)-promoting learning; that is, the development
of students' capabilities including those of question asking (QA), critical/system thinking (CST), decision making (DM), problem
solving (PS), conceptualisation of fundamental concepts (CFC) and the transfer of these within both the science disciplines and real life interdisciplinary situations. Accordingly, an innovative metacognition-promoting
science teacher professional development course, integrating formal and informal science education, was developed and implemented
within a traditional model, focusing on the HOCS skills of QA, PS, and CFC. The HOCS promoting teaching and assessment strategies
of this course not only enabled participants to reflect on their own learning, but also facilitated their self-reflective
assessment, utilising a pre–post designed research-based methodology. The results suggest that such, or similarly appropriate,
metacognition-oriented courses can contribute positively to the development of science teachers' HOCS capability. 相似文献

Both chemistry teachers and nonmajor students appear to agree that freshman chemistry may well be the most problematic traditional science discipline taught in the first year of college—as far as students' misunderstandings, learning difficulties, and misconceptions are concerned. The above is probably due to the many abstract, nonintuitive concepts, which are not directly interrelated. Consequently, in such cases, the powerful, general teaching strategy of “concept mapping” must be replaced by alternative, specific strategies. Selected illustrative examples of students' learning difficulties and misconceptions in freshman general and organic chemistry are presented in the students' terms, followed by the corresponding successfully applied, specific, concept-oriented, eclectic intervention strategies the author uses in order to overcome the difficulties. Based on longitudinal in-class observations, interpretive study, and analysis it is suggested that those students' misconceptions in freshman chemistry which are not interrelated logically and/or derived from one another are not prone to the general “concept mapping” approach and should be dealt with by using the appropriate, specific teaching strategy. 相似文献

What teaching practices foster inquiry and promote students to learn challenging subject matter in urban schools? Inquiry‐based instruction and successful inquiry learning and teaching in project‐based science (PBS) were described in previous studies (Brown & Campione, 1990 ; Crawford, 1999 ; Krajcik, Blumenfeld, Marx, Bass, & Fredricks, 1998 ; Krajcik, Blumenfeld, Marx, & Solloway, 1994 ; Minstrell & van Zee, 2000 ). In this article, we describe the characteristics of inquiry teaching practices that promote student learning in urban schools. Teaching is a major factor that affects both achievement of and attitude of students toward science (Tamir, 1998 ). Our involvement in reform in a large urban district includes the development of suitable learning materials and providing continuous and practiced‐based professional development (Fishman & Davis, in press; van Es, Reiser, Matese, & Gomez, 2002 ). Urban schools face particular challenges when enacting inquiry‐based teaching practices like those espoused in PBS. In this article, we describe two case studies of urban teachers whose students achieved high gains on pre‐ and posttests and who demonstrated a great deal of preparedness and commitment to their students. Teachers' attempts to help their students to perform well are described and analyzed. The teachers we discuss work in a school district that strives to bring about reform in mathematics and science through systemic reform. The Center for Learning Technologies in Urban Schools (LeTUS) collaborates with the Detroit Public Schools to bring about reform in middle‐school science. Through this collaboration, diverse populations of urban‐school students learn science through inquiry‐oriented projects and the use of various educational learning technologies. For inquiry‐based science to succeed in urban schools, teachers must play an important role in enacting the curriculum while addressing the unique needs of students. The aim of this article is to describe patterns of good science teaching in urban school. © 2006 Wiley Periodicals, Inc. J Res Sci Teach 43: 722–745, 2006 相似文献

Higher and lower-order cognitive skills: The case of chemistry 总被引：2，自引：0，他引：2
A major driving force in the current effort to reform science education is the conviction that it is vital for our students
to develop their higher-order cognitive skills capacity in order to function effectively in our modem, complex science and
technology-based society. In line with this rationale, this study focuses on the use of examinations for studying student
performance in chemistry examination on items that require higher-order cognitive skills (HOCS) or lower-order cognitive skills
(LOCS). This usage of examinations is explored and demonstrated via “post-factum” data analysis of two case studies: the General
Examination (in chemistry) and the Panhellenic Chemistry Competition administered natinally in Greece for secondary-school
graduates in 1991. The main findings were: (a) students performed considerably lower on questions requiring HOCS than on those
requiring LOCS; (b) performance on questions requiring HOCS may not correlate with that on questions requiring LOCS for which
affective factors, LOCS-orientation in teaching and the extent of prior examination preparation may be responsible; and (c)
examinations that contain intems of both types can be effectively used to identify HOCS- and LOCS- students within various
contexts of chemistry teaching. Based on the above and previous related studies, the fostering of students' HOCS by appropriate
teaching and assessment trategies is advocated. 相似文献

The use of inquiry‐based laboratory in college science classes is on the rise. This study investigated how five nonmajor biology students learned from an inquiry‐based laboratory experience. Using interpretive data analysis, the five students' conceptual ecologies, learning beliefs, and science epistemologies were explored. Findings indicated that students with constructivist learning beliefs tended to add more meaningful conceptual understandings during inquiry labs than students with positivist learning beliefs. All students improved their understanding of experiment in biology. Implications for the teaching of biology labs are discussed. © 2003 Wiley Periodicals, Inc. J Res Sci Teach 40: 986–1024, 2003 相似文献

Today’s society is continuously coping with sustainability‐related complex issues in the Science‐Technology‐Environment‐Society (STES) interfaces. In those contexts, the need and relevance of the development of students’ higher‐order cognitive skills (HOCS) such as question‐asking, critical‐thinking, problem‐solving and decision‐making capabilities within science teaching have been argued by several science educators for decades. Three main objectives guided this study: (1) to establish “base lines” for HOCS capabilities of 10th grade students (n = 264) in the Israeli educational system; (2) to delineate within this population, two different groups with respect to their decision‐making capability, science‐oriented (n = 142) and non‐science (n = 122) students, Groups A and B, respectively; and (3) to assess the pre‐post development/change of students’ decision‐making capabilities via STES‐oriented HOCS‐promoting curricular modules entitled Science, Technology and Environment in Modern Society (STEMS). A specially developed and validated decision‐making questionnaire was used for obtaining a research‐based response to the guiding research questions. Our findings suggest that a long‐term persistent application of purposed decision‐making, promoting teaching strategies, is needed in order to succeed in affecting, positively, high‐school students’ decision‐making ability. The need for science teachers’ involvement in the development of their students’ HOCS capabilities is thus apparent. 相似文献

What are the barriers to technology‐rich inquiry pedagogy in urban science classrooms, and what kinds of programs and support structures allow these barriers to be overcome? Research on the pedagogical practices within urban classrooms suggests that as a result of many constraints, many urban teachers' practices emphasize directive, controlling teaching, that is, the “pedagogy of poverty” (Haberman, 1991 ), rather than the facilitation of students' ownership and control over their learning, as advocated in inquiry science. On balance, research programs that advocate standards‐based or inquiry teaching pedagogies demonstrate strong learning outcomes by urban students. This study tracked classroom research on a technology‐rich inquiry weather program with six urban science teachers. The teachers implemented this program in coordination with a district‐wide middle school science reform. Results indicated that despite many challenges in the first year of implementation, students in all 19 classrooms of this program demonstrated significant content and inquiry gains. In addition, case study data comprised of twice‐weekly classroom observations and interviews with the six teachers suggest support structures that were both conducive and challenging to inquiry pedagogy. Our work has extended previous studies on urban science pedagogy and practices as it has begun to articulate what role the technological component plays either in contributing to the challenges we experienced or in helping urban science classrooms to realize inquiry science and other positive learning values. Although these data outline results after only the first year of systemic reform, we suggest that they begin to build evidence for the role of technology‐rich inquiry programs in combating the pedagogy of poverty in urban science classrooms. © 2002 John Wiley & Sons, Inc.

Responses to a written beliefs test for 178 eighth grade students and interviews with a subset of the students are analysed to investigate students' beliefs about the tentativeness of scientific knowledge and about the autonomy and strategies appropriate for science learning. These three dimensions of beliefs are salient because they align with the image of science teaching promoted by current reform movements. Analyses focus on change in beliefs and relationships among dimensions of beliefs and between those beliefs and students' understandings of science concepts. Results show that students' beliefs do not change much during the one-semester course. Students who view scientific knowledge as tentative also try to understand science. Autonomous students do not hold the most productive learning strategies, though students with low autonomy develop significantly less coherent understandings of science concepts. Instructional implications focus on potential roles of teachers and technology in promoting productive beliefs about scientific knowledge and science learning. Implications for individualized instruction follow classroom-level implications. 相似文献

Teachers' learning to facilitate high‐level student thinking: Impact of a video‐based professional development 
下载免费PDF全文
下载免费PDF全文 Attaining the vision for science teaching and learning emphasized in the Framework for K‐12 Science Education and the next generation science standards (NGSS) will require major shifts in teaching practices in many science classrooms. As NGSS‐inspired cognitively demanding tasks begin to appear in more and more science classrooms, facilitating students' engagement in high‐level thinking as they work on these tasks will become an increasingly important instructional challenge to address. This study reports findings from a video‐based professional development effort (i.e., professional development [PD] that use video‐clips of instruction as the main artifact of practice to support teacher learning) to support teachers' learning to select cognitively demanding tasks and to support students' learning during the enactment of these tasks in ways that are aligned with the NGSS vision. Particularly, we focused on the NGSS's charge to get students to make sense of and deeply think about scientific ideas as students try to explain phenomena. Analyses of teachers' pre‐ and post‐PD instruction indicate that PD‐participants began to adopt instructional practices associated with facilitating these kinds of student thinking in their own classrooms. The study has implications for the design of video‐based professional development for science teachers who are learning to facilitate the NGSS vision in science classrooms. 相似文献

This study examined prospective elementary teachers' learning about scientific inquiry in the context of an innovative life science course. Research questions included: (1) What do prospective elementary teachers learn about scientific inquiry within the context of the course? and (2) In what ways do their experiences engaging in science investigations and teaching inquiry‐oriented science influence prospective elementary teachers' understanding of science and science learning and teaching? Eleven prospective elementary teachers participated in this qualitative, multi‐participant case study. Constant comparative analysis strategies attempted to build abstractions and explanations across participants around the constructs of the study. Findings suggest that engaging in scientific inquiry supported the development more appropriate understandings of science and scientific inquiry, and that prospective teachers became more accepting of approaches to teaching science that encourage children's questions about science phenomena. Implications include careful consideration of learning experiences crafted for prospective elementary teachers to support the development of robust subject matter knowledge. 相似文献

This study addressed the question of how to increase students' competencies for regulating their co‐construction of knowledge when tackling complex collaborative learning tasks which are increasingly emphasized as a dimension of educational reform. An intervention stressing the metacognitive, regulatory, and strategic aspects of knowledge co‐construction, called Thinking Aloud Together, was embedded within a 12‐week science unit on building mental models of the nature of matter. Four classes of eighth graders received the intervention, and four served as control groups for quantitative analyses. In addition, the interactions of 24 students in eight focal groups were profiled qualitatively, and 12 of those students were interviewed twice. Students who received the intervention gained in metacognitive knowledge about collaborative reasoning and ability to articulate their collaborative reasoning processes in comparison to students in control classrooms, as hypothesized. However, the treatment and control students did not differ either in their abilities to apply their conceptual knowledge or in their on‐line collaborative reasoning behaviors in ways that were attributable to the intervention. Thus, there was a gap between students' metacognitive knowledge about collaborative cognition and their use of collaborative reasoning skills. Several reasons for this result are explored, as are patterns relating students' outcomes to their perspectives on learning science. © 1999 John Wiley & Sons, Inc.

This article examines the work conducted by two teacher-researchers involved in a study of their students' learning behaviours in their science classes. The teacher-researchers were strongly influenced by the PEEL project (Project to Enhance Effective Learning) and became members of the PAVOT project (Perspective and Voice of the Teacher) through which the research reported in this article was conducted. The teacher-researchers studied their students' approaches to learning and then introduced new teaching strategies (drawn from the PEEL literature) designed to positively influence their students' learning behaviours. In implementing new teaching strategies and exploring how their students' learning behaviours altered, these teacher-researchers suggest a number of important issues about the teaching and learning environment. The article also illustrates the importance of teacher-researchers being able to find ways of communicating their professional knowledge to the larger education community. 相似文献

In Portugal, the number of students in higher education increased from 80,000 in 1975 to 381,000 in 2000 (a change from 11% to 53% in the age group 18–22), meaning a major change in the diversity of student population with consequences well known and studied in other countries. The teaching of chemistry at the University of Aveiro, for the first‐year students of science and engineering, has been subjected to continuous attention to implement quality and student‐centred approaches. The work devoted to excellence and deep learning by several authors has been carefully followed and considered. This communication reports research work on chemistry teaching, associated with those developments for first‐year students. The work included the design of strategies and the adoption of teaching and learning activities exploring ways to stimulate active learning by improving the quality of classroom interactions. In addition to regular lectures, large classes' teaching based on student‐generated questions was explored. In order to improve students' motivation and stimulate their curiosity, conference‐lectures were adopted to deal with selected topics of wide scientific, technological and social interest. Quantitative analysis and discussion of selected case studies, together with the organization of laboratory classes based on selected enquiry‐based experiments, planned and executed by students, stimulated deep learning processes. A sample of 32 students was followed in the academic year of 2000/01 and the results obtained are here discussed in comparison with those of a sample of 100 students followed in 2001/02. Particular attention was paid to the quality of classroom interactions, the use of questions by students and their views about the course design. 相似文献

A composite theory of college science student note‐taking strategies was derived from a periodic series of five interviews with 23 students and with other variables, including original and final versions of notes analyzed during a semester‐long genetics course. This evolving composite theory was later compared with Van Meter, Yokoi, and Pressley's (Journal of Educational Psychology, 86, 323–338, 1994) corresponding composite “college students' theory of note‐taking.” Students' notes in this long‐term study were also compared with a standard of “adequate” note‐taking established by experts. Analyses detected many similarities between the two composite theories. Analyses also provided evidence of inadequate note‐taking strategies, inconsistencies between what students claimed and evidently did with their notes, and weak self‐regulating learning strategies. Recommendations included prompting students during class on how to take notes. © 2006 Wiley Periodicals, Inc. J Res Sci Teach 43: 786–818, 2006 相似文献

The current reform movement in science education promotes standards‐based teaching, including the use of inquiry, problem solving, and open‐ended questioning, to improve student achievement. This study examines the influence of standards‐based teaching practices on the achievement of urban, African‐American, middle school science students. Science classes of teachers who had participated in the professional development (n = 8) of Ohio's statewide systemic initiative (SSI) were matched with classes of teachers (n = 10) who had not participated. Data were gathered using group‐administered questionnaires and achievement tests that were specifically designed for Ohio's SSI. Analyses indicate that teachers who frequently used standards‐based teaching practices positively influenced urban, African‐American students' science achievement and attitudes, especially for boys. Additionally, teachers' involvement in the SSI's professional development was positively related to the reported use of standards‐based teaching practices in the classroom. The findings support the efficacy of high‐quality professional development to change teaching practices and to enhance student learning. © 2000 John Wiley & Sons, Inc.
