This study (1) explores the effectiveness of the contextualized history of science on student learning of nature of science
(NOS) and genetics content knowledge (GCK), especially interrelationships among various genetics concepts, in high school
biology classrooms; (2) provides an exemplar for teachers on how to utilize history of science in genetics instruction; and
(3) suggests a modified concept mapping assessment tool for both NOS and GCK. A quasi-experimental control group research
design was utilized with pretests, posttests, and delayed posttests, combining qualitative data and quantitative data. The
experimental group was taught with historical curricular lessons, while the control group was taught with non-historical curricular
lessons. The results indicated that students in the experimental group developed better understanding in targeted aspects
of NOS immediately after the intervention and retained their learning 2 months after the intervention. Both groups developed
similar genetics knowledge in the posttest, and revealed a slight decay in their understanding in the delayed posttest. 相似文献

Concept inventories, consisting of multiple-choice questions designed around common student misconceptions, are designed to reveal student thinking. However, students often have complex, heterogeneous ideas about scientific concepts. Constructed-response assessments, in which students must create their own answer, may better reveal students' thinking, but are time- and resource-intensive to evaluate. This report describes the initial meeting of a National Science Foundation-funded cross-institutional collaboration of interdisciplinary science, technology, engineering, and mathematics (STEM) education researchers interested in exploring the use of automated text analysis to evaluate constructed-response assessments. Participants at the meeting shared existing work on lexical analysis and concept inventories, participated in technology demonstrations and workshops, and discussed research goals. We are seeking interested collaborators to join our research community. 相似文献

Due to tremendous worldwide changes, the entrepreneurial imperative demands innovation. Therefore, companies as well as employees require innovative thinking and acting skills to cope with modern challenges. Opportunity Recognition represents the starting point for such entrepreneurial endeavours. Hence, this paper focuses on modelling Opportunity Recognition as well as the development of an Opportunity Recognition competence model as the foundation for teaching and learning in vocational education. Building on vocational situations that trigger innovations (opportunities) and the necessary competence facets that are needed to apply competent vocational behaviour in such situations (Opportunity Recognition), we conduct a systematic literature review and develop a comprehensive Opportunity Recognition competence model. We thereby link the found vocational situations (opportunities) with the found more abstract and latent competence facets of Opportunity Recognition and operationalise them by more observable indicators, which can be construed as evidence for the latent construct and related to successful performance in associated vocational situations. This modelling procedure of “evidence-based reasoning” allows inferences from the observed behaviour to the underlying, although not directly observable, Opportunity Recognition competence. The resulting Opportunity Recognition competence model may serve as a foundation for developing evidence-based curricular goals for vocational education through both instruction and assessment. 相似文献

Results and Implications of a 12-Year Longitudinal Study of Science Concept Learning 总被引：2，自引：0，他引：2

This paper describes the methods and outcomes of a 12-year longitudinal study into the effects of an early intervention program, while reflecting back on changes that have occurred in approaches to research, learning and instruction since the preliminary inception stages of the study in the mid 1960s. We began the study to challenge the prevailing consensus at the time that primary school children were either preoperational or concrete operational in their cognitive development and they could not learn abstract concepts. Our early research, based on Ausubelian theory, suggested otherwise. The paper describes the development and implementation of a Grade 1–2 audio tutorial science instructional sequence, and the subsequent tracing over 12 years, of the children’s conceptual understandings in science compared to a matched control group. During the study the concept map was developed as a new tool to trace children’s conceptual development. We found that students in the instruction group far outperformed their non-instructed counterparts, and this difference increased as they progressed through middle and high school. The data clearly support the earlier introduction of science instruction on basic science concepts, such as the particulate nature of matter, energy and energy transformations. The data suggest that national curriculum standards for science grossly underestimate the learning capabilities of primary-grade children. The study has helped to lay a foundation for guided instruction using computers and concept mapping that may help both teachers and students become more proficient in understanding science. 相似文献

History teachers, teacher–researchers, government agencies and history education academics in England often report that students are frequently incapable of producing complex, polythetic or developmental narratives over long time scales. This lack of an overview tends to result in deficiencies in their application of the key concepts of the discipline. Consequently Shemilt has recommended the use of synoptic, millennia-wide ‘frameworks’ of knowledge in order to counteract these issues. With some notable exceptions, however, practising history teachers have appeared sceptical of the benefits of such an approach. I conducted an exploratory case study investigating in what ways a pre-taught framework, in which I had responded to some practitioners’ criticisms, appeared to be manifested in my students’ subsequent thinking regarding historical significance. My goal was to contribute to professional curricular theorising about what constitutes a framework and how it might be expressed as a curricular goal. Themes were derived from pupils’ writing, lesson evaluations, group interviews and observations. Possible curricular goals that were characterised in the students’ work included the pupils producing millennia-wide narratives based on colligatory generalisations and assessments of historical significance incorporating scale-shifting over long time scales. 相似文献

Science education in the United States will increasingly be driven by testing and accountability requirements, such as those mandated by the No Child Left Behind Act, which rely heavily on learning outcomes, or "standards," that are currently developed on a state-by-state basis. Those standards, in turn, drive curriculum and instruction. Given the importance of standards to teaching and learning, we investigated the quality of life sciences/biology standards with respect to genetics for all 50 states and the District of Columbia, using core concepts developed by the American Society of Human Genetics as normative benchmarks. Our results indicate that the states' genetics standards, in general, are poor, with more than 85% of the states receiving overall scores of Inadequate. In particular, the standards in virtually every state have failed to keep pace with changes in the discipline as it has become genomic in scope, omitting concepts related to genetic complexity, the importance of environment to phenotypic variation, differential gene expression, and the differences between inherited and somatic genetic disease. Clearer, more comprehensive genetics standards are likely to benefit genetics instruction and learning, help prepare future genetics researchers, and contribute to the genetic literacy of the U.S. citizenry. 相似文献

Our main goal in this study was to explore whether the use of models in molecular genetics instruction in high school can contribute to students' understanding of concepts and processes in genetics. Three comparable groups of 11th and 12th graders participated: The control group (116 students) was taught in the traditional lecture format, while the others received instructions which integrated a bead model (71 students), or an illustration model (71 students). Similar instructions and the same guiding questions accompanied the two models. We used three instruments: a multiple‐choice and an open‐ended written questionnaire, as well as personal interviews. Five of the multiple‐choice questions were also given to students before receiving their genetics instruction (pretest). We found that students who used one of the two types of models improved their knowledge in molecular genetics compared to the control group. However, the open‐ended questions revealed that bead model activity was significantly more effective than illustration activity. On the basis of these findings we conclude that, though it is advisable to use a three‐dimensional model, such as the bead model, engaging students in activities with illustrations can still improve their achievement in comparison to traditional instruction. © 2006 Wiley Periodicals, Inc.

This article is part of a special LDRP research-to-practice series introducing key concepts to enable special education practitioners and other nonresearchers to be more informed research consumers. In the article, we explore how social validity is assessed in special education research and how to interpret social validity assessments. Rather than focusing on measuring intervention effects, social validity involves assessing the social importance of the goals, procedures, and outcomes of interventions and programs. We define social validity, provide questions to consider when examining assessments of social validity in research papers, review approaches commonly used to assess social validity with examples from the research literature, and make recommendations for reconciling findings of positive intervention effects on targeted outcomes but absent or negative findings related to social validity in a study. Our take-home message is that considering social validity assessments helps research consumers interpret study findings and informs how to apply findings in practice. 相似文献

This study investigates the potential of enhancing students' learning of difficult science concepts by exploring the interaction
between teachers' four different instructional approaches and students' four different learning preference styles. Students'
immediate performance and their retention for learning of buoyancy concepts serve to examine the effects, using the concept
of “buoyancy,” which has been classified as a difficult concept because it is at a higher hierarchical level and involves
the understanding of both matter and process. Results indicate that students' post-test scores were significantly affected
by both the types of instruction and students' learning preference styles; while students' retention test scores were significantly
affected by the types of instructions. Moreover, this study does not support that matching teaching style with students' learning
preference would make students' learning more effective. Nevertheless, because procedural learning preference styles (QB-learning
preference) students performed better on the retention test than other learning preference styles students, it indicates the
possibility that procedural learners are more efficient than others for learning such higher hierarchical and difficult concepts,
regardless of the types of instruction students receive. 相似文献

Lately, scholars have argued that there is a consensus on a number of critical features of effective teacher professional development (PD). This study presents the results of a systematic review of one of these features: coherence. The analysis and synthesis of 95 papers show that coherence in PD is conceptualized in various ways, and thus that the aforementioned consensus can be questioned. For example, should PD (1) be coherent with external factors, such as standards and assessments; (2) be internally coherent, for example that activities within PD programs should be aligned; or (3) create coherence between goals that are either predetermined or negotiated together with teachers? The different conceptualizations of coherence all implicate how teachers are positioned in relation to PD programs and, in the light of our results, we argue that teachers are primarily seen as implementers expected to align their instruction with external and predetermined goals and practices. 相似文献

Genetics is the cornerstone of modern biology and understanding genetics is a critical aspect of scientific literacy. Research
has shown, however, that many high school graduates lack fundamental understandings in genetics necessary to make informed
decisions or to participate in public debates over emerging technologies in molecular genetics. Currently, much of genetics
instruction occurs at the high school level. However, recent policy reports suggest that we may need to begin introducing
aspects of core concepts in earlier grades and to successively develop students’ understandings of these concepts in subsequent
grades. Given the paucity of research about genetics learning at the middle school level, we know very little about what students
in earlier grades are capable of reasoning about in this domain. In this paper, we discuss a research study aimed at fostering
deeper understandings of molecular genetics at the middle school level. As part of the research we designed a two-week model-based
inquiry unit implemented in two 7th grade classrooms (N = 135). We describe our instructional design and report results based on analysis of pre/post assessments and written artifacts
of the unit. Our findings suggest that middle school students can develop: (a) a view of genes as productive instructions
for proteins, (b) an understanding of the role of proteins in mediating genetic effects, and (c) can use this knowledge to
reason about a novel genetic phenomena. However, there were significant differences in the learning gains in both classrooms
and we provide speculative explanations of what may have caused these differences. 相似文献

Recent developments in the field of genomics will impact the daily practice of biology teachers who teach genetics in secondary education. This study reports on the first results of a research project aimed at enhancing biology teacher knowledge for teaching genetics in the context of genetic testing. The increasing body of scientific knowledge concerning genetic testing and the related consequences for decision-making indicate the societal relevance of such a situated learning approach. What content knowledge do biology teachers need for teaching genetics in the personal health context of genetic testing? This study describes the required content knowledge by exploring the educational practice and clinical genetic practices. Nine experienced teachers and 12 respondents representing the clinical genetic practices (clients, medical professionals, and medical ethicists) were interviewed about the biological concepts and ethical, legal, and social aspects (ELSA) of testing they considered relevant to empowering students as future health care clients. The ELSA suggested by the respondents were complemented by suggestions found in the literature on genetic counselling. The findings revealed that the required teacher knowledge consists of multiple layers that are embedded in specific genetic test situations: on the one hand, the knowledge of concepts represented by the curricular framework and some additional concepts (e.g. multifactorial and polygenic disorder) and, on the other hand, more knowledge of ELSA and generic characteristics of genetic test practice (uncertainty, complexity, probability, and morality). Suggestions regarding how to translate these characteristics, concepts, and ELSA into context-based genetics education are discussed. 相似文献

Based on the multidisciplinary field of multimodality, this paper offers a theoretical perspective on the construct of a curricular
concept which is commonly used in a school curriculum and applies it to an analysis of a typical curricular text and classroom
instruction that exposit the physics concept of work–energy. Theorizing a concept as a network of meaning relationships across
multiple modes of representation situated in human activity, this approach examines how we can recognize the meaning constructed
through the semantic relationships of language and its contextualization with pictorial, graphical, and numerical resources.
The value of this approach to curriculum and instruction in formal educational settings is also presented. 相似文献

Music, visual arts and design instruction has hardly been studied by the educational research community in Switzerland. Beyond a narrow group of specialists, there is little aware-ness of the basic pedagogical premises, subject matter expertise and the theoretical underpinnings of music visual art and design education although these areas of instruction are firmly anchored in the education goals for compulsory public schooling that have been outlined at national level in Switzerland and a generous amount of instructional time appears to be allocated to these subject areas in comparison with curriculum guidelines in other countries. This paper presents the findings of a trend analysis focused on music, visual arts and design instruction in Switzerland. It shows the importance accorded to aesthetic subjects within the scope of compulsory public education, explores differences in the amount of time resources allocated to these subject areas and describes the subject-specific and cross-functional goals and objectives. Teacher education programs are also examined as their current content and structure raise concerns about inadequate teacher qualifications that contradict the ambitious curricular goals. A review of previous research efforts, most of which have explored the transfer effects of creative, artistic subject areas, follows and desiderata with respect to the future development of research activities are presented. 相似文献

Experts are more proficient in manipulating and translating between multiple representations (MRs) of a given concept than novices. Studies have shown that instruction using MR can increase student understanding of MR, and one model for MR instruction in chemistry is the chemistry triplet proposed by Johnstone. Concreteness fading theory suggests that presenting concrete representations before abstract representations can increase the effectiveness of MR instruction; however, little work has been conducted on varying the order of different representations during instruction and the role of concreteness in assessment. In this study, we investigated the application of concreteness fading to MR instruction and assessment in teaching chemistry. In two experiments, undergraduate students in either introductory psychology courses or general chemistry courses were given MR instruction on phase changes using different orders of presentation and MR assessment questions based on the representations in the chemistry triplet. Our findings indicate that the order of presentation based on levels of concreteness in MR chemistry instruction is less important than implementation of comprehensive MR assessments. Even after MR instruction, students display an asymmetric understanding of the chemical phenomenon on the MR assessments. Greater emphasis on MR assessments may be an important component in MR instruction that effectively moves novices toward more expert MR understanding. 相似文献

The present study examined the comparative effects of a prediction/discussion‐based learning cycle, conceptual change text (CCT), and traditional instructions on students' understanding of genetics concepts. A quasi‐experimental research design of the pre‐test–post‐test non‐equivalent control group was adopted. The three intact classes, taught by the same science teacher, were randomly assigned as prediction/discussion‐based learning cycle class (N = 30), CCT class (N = 25), and traditional class (N = 26). Participants completed the genetics concept test as pre‐test, post‐test, and delayed post‐test to examine the effects of instructional strategies on their genetics understanding and retention. While the dependent variable of this study was students' understanding of genetics, the independent variables were time (Time 1, Time 2, and Time 3) and mode of instruction. The mixed between‐within subjects analysis of variance revealed that students in both prediction/discussion‐based learning cycle and CCT groups understood the genetics concepts and retained their knowledge significantly better than students in the traditional instruction group. 相似文献

The authors explored the credibility of using informal reading inventories and writing samples for 138 students (K–4) to evaluate the effectiveness of a summer literacy program. Running Records (a measure of a child's reading level) and teacher experience during daily reading instruction were used to estimate the reliability of the more formal Developmental Reading Assessment scores. Training of scorers was used to increase the reliability of writing scores; a second scoring was used to estimate the reliability of the scores. The results suggested that with minimal modifications to administration and scoring procedures, scores from both reading inventories and writing samples can be a dependable source of data for teachers, administrators, and policy makers. This result is significant because it suggests that formative literacy assessments can be reliably used instead of standardized multiple-choice tests to make more credible summative decisions without taking time away from instruction, and can truly match curriculum, instruction, and assessment. 相似文献
