Career and educational opportunities in food science and food safety are underrecognized by K‐12 students and educators. Additionally, misperceptions regarding nature of science understanding persist in K‐12 students despite being emphasized as an important component of science education for over 100 y. In an effort to increase awareness concerning career and educational opportunities in food science and food safety and to improve the nature of science understanding among K‐12 students, a series of problem‐based learning modules was developed and pilot tested with a total of 61 K‐12 students. Results of pre‐ and postevaluations and assessments indicated that (1) interest in science, food science, and food safety increased and (2) content knowledge related to the nature of science, food science, and food safety was improved. We further suggest that these modules provide opportunities for educators in traditional as well as extracurricular settings to demonstrate important concepts contained in the newly released Next Generation Science Standards. 相似文献

The present project embarked on an educational intervention, consisting of a series of online ethics learning modules, to
aid international graduate students in overcoming the acculturation barriers to understanding and inculcating normative ethical
obligations associated with engineering practice and research in the United States. A fundamental initial step in the process
of helping international, as well as domestic, engineering graduate students embrace ethical obligations is to provide clear
instruction on fundamental engineering ethical principles and values relevant in the United States. Most institutes of higher
education do not have a cohesive approach to basic graduate engineering ethics instruction, much less materials that have
been calibrated for international students (National Science Foundation, , 2009). Herein the authors describe our instructional intervention, as well as to document the development, design, and assessment
of the learning modules intended to provide students with a framework for learning ethical precepts and applying them in the
engineering field. Think-Aloud Protocol and Cognitive Task Analysis results were used to improve the content modules and learning
experience. Initial pilot findings indicate that the content modules increased student knowledge acquisition compared to pre-test
performance, indicating a step-forward in the formulation of a useful learning tool for graduate engineering ethics instruction. 相似文献

Historical excurse was suggested as a beneficial form of using the history and philosophy of science in the modules of learning materials developed within the History and Philosophy in Science Teaching project. The paper briefly describes the theoretical framework of the produced modules, addressing ontological and epistemological aspects of historical changes in physics knowledge with regard to several particular concepts relevant to school course of physics. It is argued that such excurses create Cultural Content Knowledge which improves the Pedagogical Content Knowledge in teachers and are appropriate to facilitate the meaningful learning by students. The modules illustrate the new aspect of the scientific knowledge not sufficiently addressed in the current science educational discourse??the constructive diachronic discourse that took place in the history. Historical excurse makes explicit the paradigmatic conceptual changes in physics knowledge and thus creates the space of learning in which the ??correct?? knowledge (type I) emerges in a discourse with the alternates (type II knowledge). Some of the previous conceptions show certain similarity to students?? misconceptions which further motivates essential use of both types of scientific knowledge to support the meaningful learning of physics curriculum. The epistemological aspects of the developed materials illuminate the nature of scientific knowledge and its major features: objectiveness and cumulative nature. Teachers found the developed modules interesting, important but challenging their background and requiring special preparation. 相似文献

The development of transferrable skillsets, articulated in statements of graduate learning outcomes, is emphasised in undergraduate science degree programmes. Science students enrolled in dual (double) degrees comprise a significant minority of Australian science undergraduates. Research comparing perceptions of single and dual degree students on their science learning outcomes has rarely been explored. The Science Students Skills Inventory was used to compare the perceptions of single (n = 640) and dual (n = 266) degree undergraduate science students. The instrument explored science graduate learning outcomes across six indicators: importance; the extent to which outcomes were included; the extent to which they were assessed; improvement; confidence; and likely future use. Analysis of findings, employing the planned–enacted–experienced curricula framework, offers insight into potential avenues towards coherence of the experienced curriculum by arguing the need for shared perceptions of graduate learning outcomes for single and dual degree science students. The key contribution of this study is a shift towards progressive curriculum development that draws on both single and dual degree student perspectives to achieve graduate learning outcomes. Recommendations include: whole-of-programmes curricular pathways premised on progressive development of learning outcomes that are inclusive of dual degree students, explicit interdisciplinary learning opportunities, and adoption of dual/single status as a demographic variable reported in future research. 相似文献

The BIO2010 report provided a compelling argument for the need to create learning experiences for undergraduate biology students that are more authentic to modern science. The report acknowledged the need for research that could help practitioners successfully create and reform biology curricula with this goal in mind. Our objective in this article was to explore how a set of six design heuristics could be used to evaluate the potential of curricula to support productive learning experiences for science students. We drew on data collected during a long-term study of an undergraduate traineeship that introduced students to mathematical modeling in the context of modern biological problems. We present illustrative examples from this curriculum that highlight the ways in which three heuristics—instructor role-modeling, holding students to scientific norms, and providing students with opportunities to practice these norms—consistently supported learning across the curriculum. We present a more detailed comparison of two different curricular modules and explain how differences in student authority, problem structure, and access to resources contributed to differences in productive engagement by students in these modules. We hope that our analysis will help practitioners think in more concrete terms about how to achieve the goals set forth by BIO2010. 相似文献

In this article, the authors, students in an instructional technology graduate course, describe a process to create an online tutorial for teaching software. They created the tutorial for a cyber school's use. Five tutorial modules were linked together through one menu screen using the MenuBuilder feature in the Adobe Captivate program. The separate modules allowed the cyber school's students to customize their learning, whereas the entire tutorial allowed teachers to concentrate class time on teaching lesson objectives, rather than software. 相似文献

The University of Rochester's Graduate Experience in Science Education (GESE) course familiarizes biomedical science graduate students interested in pursuing academic career tracks with a fundamental understanding of some of the theory, principles, and concepts of science education. This one-semester elective course provides graduate students with practical teaching and communication skills to help them better relate science content to, and increase their confidence in, their own teaching abilities. The 2-h weekly sessions include an introduction to cognitive hierarchies, learning styles, and multiple intelligences; modeling and coaching some practical aspects of science education pedagogy; lesson-planning skills; an introduction to instructional methods such as case studies and problem-based learning; and use of computer-based instructional technologies. It is hoped that the early development of knowledge and skills about teaching and learning will encourage graduate students to continue their growth as educators throughout their careers. This article summarizes the GESE course and presents evidence on the effectiveness of this course in providing graduate students with information about teaching and learning that they will use throughout their careers. 相似文献

With the rapid expansion of graduate education in China, graduate curriculum evaluation has aroused great concern from the administrators and researchers. Many colleges and universities have developed their graduate curriculum evaluation system based on educational policy, job analysis or discussions of school administrators. To date, very few systemic studies in this field have been done in China, and little is known about students’ view on the evaluation system. In this study, 30 second-year graduate students from a comprehensive university were selected to participate in a semi-structured interview. It was found that graduate students attached more importance to the following 5 aspects: 1) The curriculum objectives should be employment-oriented and in line with students’ need of future employment and long-term development; 2) The curriculum content should be up to date and its breadth and depth of coverage are appropriate; 3) The instructor's teaching approaches should be flexible and varied, emphasizing student participation and teacher-student interaction; 4) The learning evaluation should be conducted fairly and reasonably in various ways; 5) The curriculum should be able to effectively promote students’ mastery of knowledge and capacities. This study will provide the evidence for rethinking and improving graduate curriculum evaluation system. 相似文献

This paper reports a test on the feasibility and educational value of probeware and associated instructional materials in middle school science education. We addressed feasibility through consideration of costs, teacher professional development, and instructional design. In order to test our approach, we developed 2 middle school science curriculum units, 6 low-cost probes that interface between handheld Palm computers, and CCLabBook software for the Palms that presents the curriculum, interfaces with the probes for data collection and visualization, and supports guided exploration. The materials were tested by 30 teachers in the first year, and in a follow-up study by 8 of those teachers the second year. We found that teachers were able to conduct the investigations successfully in their classrooms, and that student learning was enhanced through the use of the probes and handhelds. Specifically, students experienced the physical correlation between phenomenon and modeling, which helped them to develop understanding and to confront misconceptions. 相似文献

ABSTRACTThis study investigated students’ perceptions of their graduate learning outcomes including content knowledge, communication, writing, teamwork, quantitative skills, and ethical thinking in two Australian universities. One university has a traditional discipline-orientated curriculum and the other, an interdisciplinary curriculum in the entry semester of first year. The Science Students Skills Inventory asked students (n?=?613) in first and final years to rate their perceptions of the importance of developing graduate learning outcomes within the programme; how much they improved their graduate learning outcomes throughout their undergraduate science programme; how much they saw learning outcomes included in the programme; and how confident they were about their learning outcomes. A framework of progressive curriculum development was adopted to interpret results. Students in the discipline-oriented degree programme reported higher perceptions of scientific content knowledge and ethical thinking while students from the interdisciplinary curriculum indicated higher perceptions of oral communication and teamwork. Implications for curriculum development include ensuring progressive development from first to third years, a need for enhanced focus on scientific ethics, and career opportunities from first year onwards. 相似文献

Children with developmental language disorder (DLD) exhibit weaknesses in the syntactic aspects of language that affect their spoken language (i.e., speaking and listening) and written language (i.e., reading and writing). Speech-language pathologists (SLP) who work with children with DLD are the team member with the greatest expertise in syntax. However, emerging data suggest that speech-language pathology (SLP) students and SLPs have limitations in their explicit syntax knowledge that may affect how they assess and treat the language and literacy knowledge and skills of children with DLD. Additionally, there is a lack of data on the outcomes of professional development specific to syntax. This paper reports on the effects of self-paced, online learning modules on SLP graduate students’ explicit syntax knowledge. Thirty-six SLP graduate students completed online syntax learning modules that taught four pairs of syntactic structures. SLP graduate students experienced a treatment effect from two of the four online training modules. Treatment effects seemed to be influenced by the syntactic skill being treated, by prior knowledge of that particular syntactic structure, and by other environmental factors, including training program. Although future studies should explore these factors further, the outcomes of this pilot study are the first to report on a way to improve SLP graduate students’, and potentially SLPs’, explicit syntax knowledge.

High-quality professional development is needed to prepare teachers to help students learn how to conduct online academic research and meet Common Core State Standards for English Language Arts. This study created and evaluated a Web-based professional development program with five instructional modules designed to prepare middle-school teachers to teach their students nine strategies for conducting academic research online. The online professional development program was specifically created to help teachers implement the previously developed online SOAR Student Toolkit curriculum with all students in inclusive classrooms. Results of a 2015–2016 pilot study conducted with 13 teachers and 477 students in sixth to eighth grades indicated that most teachers perceived the professional development program to be of high quality and relevant in helping them teach online research skills to their students. Students significantly improved online research skills after learning from trained teachers (27 percentage points improvement, from 18% at pretest to 45% at posttest). 相似文献

This study reports a collective case study of five science education graduate students to highlight the role of culture as an influential component within their conceptual understandings of urban science education. Conceptual change theory was used as a theoretical framework to explore the negotiations that five graduate students experienced during a semester-long ‘Urban and Multicultural Science Education’ course geared toward increasing conceptual complexity (i.e., the ways students make connections between concepts). Negotiation—the way these students’ adopted, resisted, or considered new inter-conceptual complexity—was studied through how these learners activated and applied their understandings. Findings support that culture influenced the development of conceptual complexity for the themes studied by increasing the permeability of concepts to connect to one another—coined here as conceptual porosity. This complexity is represented through the inter-conceptual connectivity that developed temporally during learning experiences. Implications for these findings are discussed, as well.

This project addresses the challenge of preparing educational leaders for future roles in administration in K–12 schools. Through a project-based learning scenario set in a 3-D virtual world, graduate students in school administration and instructional technology worked together in simulated school teams to develop proposals for integrating technology into a fictitious school. The scenario provided parameters within which each team developed a proposal to a superintendent for the use of iPads, which included developing plans for professional development, collaboration among faculty and staff, infrastructure to support the technology, alignment with curriculum, and budgets. Teams worked independently of classes to develop proposals that were then posted in the virtual world for review by instructors and other students. The simulation offered opportunities to develop shared leadership and skills in collaboration outside the usual comfort zone of graduate school classes. Student perception of the value of participation provided insight into the design of the project, which will inform future such collaborative efforts among faculty. Results of student surveys and written reflections are shared as examples of the types of data collected for this project. 相似文献

Where you live should have something to do with what you teach. In the Arctic, the idea of place-based education – teaching
and sharing knowledge that is needed to live well – is central to the UARCTIC consortium and the 4th International Polar Year educational reform effort. A place-based issue oriented context can engage students in chemistry
concepts when it intersects with their experience and lives. This article examines the rationale and means of integrating
local concerns such as world view, culture, traditional knowledge, and policy into both general and specialized chemistry
courses. More broadly, capacious placebased issues should be widely adapted by all curriculum reform efforts to demonstrate
the connectivity between science and societal understanding of technological options. A case in point is the inclusion of
indigenous perspectives in a non-majors general chemistry course when the concepts of scientific method, ice and water resources,
genetic engineering, and so forth are discussed. In a specialized course on radioactivity in the north, topics connected nuclear
chemistry and radioactivity to people and energy. The local landscape should be central to science courses and involve issues
relevant to stewardship, a component of the indigenous world view. The historical issues can be connected to current nuclear
energy and uranium mining as they relate to the risks and benefits for the local community. This article will make the case
that curriculum reform that focuses on real-world topics will not only engage students so that they perform well in class
but also spark their interest so that they continue learning after the course is over. 相似文献

Nanocourses: a short course format as an educational tool in a biological sciences graduate curriculum 
下载免费PDF全文
下载免费PDF全文 Traditional courses for graduate students in the biological sciences typically span a semester, are organized around the fundamental concepts of a single discipline, and are aimed at the needs of incoming students. Such courses demand significant time commitment from both faculty and course participants; thus, they are avoided by a subset of the academic science community. Course length and the high barrier to course development are inhibitory to the creation of new courses, especially in emerging areas of biology that may not merit a full-semester approach. Here, we describe the implementation of a new, graduate-level course format, created to allow for rapid development of courses, provide meaningful educational experiences for both junior and senior graduate students and other members of our community, and increase the breadth of faculty involvement in teaching. These courses are greatly abbreviated, and thus termed “nanocourses.” Based on experience from the first three semesters, nanocourses seem to accomplish the initial goals that we set. Importantly, nanocourses engaged students, postdoctoral fellows, faculty, and others, thus providing a new mechanism to educate our community in response to rapid advances in biology. In our view, nanocourses are a useful tool that can supplement graduate-level curricula in varied ways. 相似文献
