Health professionals and policymakers are asking educators to place more emphasis on food and nutrition education. Integrating these topics into science curricula using hand‐on, food‐based activities may strengthen students’ understanding of science concepts. The Food, Math, and Science Teaching Enhancement Resource (FoodMASTER) Initiative is a compilation of programs aimed at using food as a tool to teach mathematics and science. Previous studies have shown that students experiencing the FoodMASTER curriculum were very excited about the activities, became increasingly interested in the subject matter of food, and were able to conduct scientific observations. The purpose of this study was to: (1) assess 4th graders food‐related multidisciplinary science knowledge, and (2) compare gains in food‐related science knowledge after implementation of an integrated, food‐based curriculum. During the 2009–2010 school year, FoodMASTER researchers implemented a hands‐on, food‐based intermediate curriculum in eighteen 4th grade classrooms in Ohio (n = 9) and North Carolina (n = 9). Sixteen classrooms in Ohio (n = 8) and North Carolina (n = 8), following their standard science curricula, served as comparison classrooms. Students completed a researcher‐developed science knowledge exam, consisting of 13 multiple‐choice questions administered pre‐ and post‐test. Only subjects with pre‐ and post‐test scores were entered into the sample (Intervention n = 343; Control n = 237). No significant differences were observed between groups at pre‐test. At post‐test, the intervention group scored (9.95 ± 2.00) significantly higher (p = 0.000) than the control group (8.84 ± 2.37) on a 13‐point scale. These findings suggest the FoodMASTER intermediate curriculum is more effective than a standard science curriculum in increasing students’ multidisciplinary science knowledge related to food.  相似文献

A variance analysis of the relation between the amount of time students spent experiencing hands-on science and science achievement was performed. Data collected by the National Education Longitudinal Study of 1988 on a nationally representative sample of eighth-grade students were analyzed. Student achievement in science was measured by a cognitive test battery developed by the Educational Testing Service. Information regarding the frequency of hands-on experience was collected through a self-administered teacher questionnaire, which included a series of questions specific to the science curriculum. From the analysis it was concluded that significant differences existed across the hands-on frequency variable with respect to science achievement. Specifically, students who engaged in hands-on activities every day or once a week scored significantly higher on a standardized test of science achievement than students who engaged in hands-on activities once a month, less than once a month, or never. © 1996 John Wiley & Sons, Inc.  相似文献

Summary Science teachers naturally rely on their university science experiences as a foundation for teaching middle school science. This foundation consists of knowledge far too complex for the middle level students to comprehend. In order for middle school science teachers to utilize their university science training they must search for ways to adapt their college experiences into appropriate middle school learning experience. The criteria set forth above provide broad-based guidelines for translating university science laboratory experiences into middle school activities. These guidelines are used by preservice teachers in our project as they identify, test, and organize a resource file of hands-on inquiry activities for use in their first year classrooms. It is anticipated that this file will provide a basis for future curriculum development as the teacher becomes more comfortable and more experienced in teaching hands-on science. The presentation of these guidelines is not meant to preclude any other criteria or considerations which a teacher or science department deems important. This is merely one example of how teachers may proceed to utilize their advanced science training as a basis for teaching middle school science.  相似文献

ABSTRACT:  Providing effective food safety education to young consumers is a national health priority to combat the nearly 76 million cases of foodborne illness in the United States annually. With the tremendous pressures on teachers for accountability in core subject areas, the focus of classrooms is on covering concepts that are tested on state performance examinations. As a result, topics such as food safety are rarely addressed in middle school classrooms. Middle school is an ideal time to teach food safety because adolescents are in the process of setting lifelong behaviors; therefore, they are more likely to synthesize new food safety knowledge in a way that will lead to the development of lifelong behaviors. The purpose of this study was to scientifically validate an educational resource that provides a method for classroom teachers to involve young consumers in food safety education while meeting state content area curriculum standards. An interdisciplinary curriculum targeted at middle school students and correlated directly to state content standards was designed to include highly effective instructional strategies that teach food safety concepts through all core subject classes (science, math, social studies, and language arts). The curriculum was pilot tested in 5 schools using a pretest, posttest, and follow-up test assessment model. The results showed that the curriculum was highly effective at raising student knowledge (21% gain) and improving students' food handling behaviors (8.47% gain) from pretests to posttests. In addition, 6 wk after implementation, students retained 86% of their total knowledge gain as measured by a follow-up assessment.  相似文献

This study investigated changes in Korean science teachers' perceptions of creativity and science teaching after participating in an overseas professional development program. Participants were 35 secondary science teachers. Data were collected from open-ended questionnaires and interviews. Results indicated that participants showed a growing awareness that creativity can be expressed by every student; creativity can be enhanced; science has a much wider range of activities that foster creativity; and creativity-centered science teaching can be implemented in Korea. The major elements of the professional program that promoted these perceptual changes included hands-on creativity activities, observation of creativity-centered classrooms, and discussion with other teachers. Follow-up study revealed that their perceptual changes have been reflected in their teaching practices.  相似文献

The study examined the impact of curriculum reform on teaching practice in primary mathematics in mainland China. The participants included 58 fifth grade mathematics teachers from 20 schools. Thirty-two of the classrooms had utilized a reform curriculum for 5 years prior to conducting the study, and the remaining 26 had been using the conventional curriculum. Each of the 58 teachers was videotaped for 3 of his/her classes during a 3-day period and the videotaped class sessions provided the data source for the study. The focus of the study was on the instructional tasks that were implemented in the classrooms and on the teacher and student interaction. Results indicated that a greater proportion of high cognitive level tasks were implemented in the reform classrooms when compared to those in the non-reform classrooms. Numerical symbolic representation as well as single-solution strategies were dominant in the instructional tasks for both groups. However, in the reform classes a higher proportion of instructional tasks were used that involved visual illustrations and hands-on manipulation and multiple-solution strategies. An analysis of classroom discourse showed that most of the teacher questions were related to memorizing exercises and explanations of answers. However, the teachers from the reform classrooms were more likely to ask students to describe the procedure that led to an answer and to inquire further into students’ responses. The results indicated positive changes in classroom practice resulting from implementation of the new curriculum.  相似文献

An integrative curriculum strategy emphasizing science process skills and hands-on activities expanded the time allocated for in-depth science instruction by replacing a district-adopted basal reading program with science-content reading designed to facilitate applied comprehension skills. This study investigated the combined effect of these curricular components (i.e., in-depth science, science-content-based reading) upon student achievement, attitudes, and self-confidence in both science and reading over the school year. In doing so, teachers in three fourth-grade classrooms each incorporated applied reading (and language arts) objectives into science reading activities as part of a daily, expanded, in-depth science teaching block that encompassed the total instructional time originally allocated to reading and science. Using multivariate covariance analysis, results showed that the students in the experimental group, compared to demographically similar controls, not only displayed significantly greater standardized test achievement as measured by the Iowa Tests of Basic Skills reading subtest and the Metropolitan Achievement Test science subtest, but also displayed a more positive attitude toward science and reading and greater self-confidence in learning science. Implications of the strategy for future curriculum research in science education are discussed.  相似文献

High school students’ prevalence as food‐service industry employees and their lack of food safety knowledge make them prime candidates for food safety education. The researchers developed a food‐safety‐focused curriculum for high school students aligned with Indiana Academic Standards for Agriculture, Advanced Life Science: Food. The curriculum was designed to provide students with fundamental food safety concepts through experiential learning and incorporation of science, technology, engineering, agriculture, and mathematics (STEAM) activities in the context of different careers related to agriculture, especially in food science. This study uses the Delphi technique to evaluate the food safety curriculum, including the identification of barriers to incorporating the curriculum into classrooms. The Delphi technique uses an expert panel to generate consensus related to a topic. A panel of experts in the field of education evaluated the curriculum through three rounds of surveys containing questions related to six curriculum assessment topics. Experts rated the degree to which they agreed with statements about the curriculum using a 5‐point Likert scale and multiple‐choice questions. At the conclusion of the study, the cost to purchase materials for cooking labs was the only identified barrier to curriculum incorporation (62.5%). Experts agreed that the curriculum addressed academic standards (100%), was engaging for students (100.0%), was easy for teachers to use (89.5%), and successfully incorporated STEAM (100.0%), experiential learning (89.5%), and career‐education (78.9%). This study highlights the feasibility of providing food safety education to high school students in less traditional disciplines while promoting career development through the incorporation of experiential learning, STEAM, and career‐education components.  相似文献

This article reports on analyses of the instructional practices of six middle- and high-school science teachers in the United States who participated in a research-practice partnership that aims to support reform science education goals at scale. All six teachers were well qualified, experienced, and locally successful—respected by students, parents, colleagues, and administrators—but they differed in their success in supporting students' three-dimensional learning. Our goal is to understand how the teachers' instructional practices contributed to their similarities in achieving local success and to differences in enabling students' learning, and to consider the implications of these findings for research-practice partnerships. Data sources included classroom videos supplemented by interviews with teachers and focus students and examples of student work. We also compared students' learning gains by teacher using pre–post assessments that elicited three-dimensional performances. Analyses of classroom videos showed how all six teachers achieved local success—they led effectively managed classrooms, covered the curriculum by teaching almost all unit activities, and assessed students' work in fair and efficient ways. There were important differences, however, in how teachers engaged students in science practices. Teachers in classrooms where students achieved lower learning gains followed a pattern of practice we describe as activity-based teaching, in which students completed investigations and hands-on activities with few opportunities for sensemaking discussions or three-dimensional science performances. Teachers whose students achieved higher learning gains combined the social stability characteristic of local classroom success with more demanding instructional practices associated with scientific sensemaking and cognitive apprenticeship. We conclude with a discussion of implications for research-practice partnerships, highlighting how partnerships need to support all teachers in achieving both local and standards-based success.  相似文献

We describe a model professional development intervention currently being implemented to support 3rd- through 5th-grade teachers’ science instruction in 9 urban elementary schools with high numbers of English language learners. The intervention consists of curriculum materials for students and teachers, as well as teacher workshops throughout the school year. The curriculum materials and workshops are designed to complement and reinforce each other in improving teachers’ knowledge, beliefs, and practices in science instruction and English language development for ELL students. In addition to these primary goals, secondary goals of the intervention included supporting mathematical understanding, improving scientific reasoning, capitalizing on students’ home language and culture, and preparing students for high-stakes science testing and accountability through hands-on, inquiry-based learning experiences.  相似文献

As part of a project to identify opportunities for reasoning that occur in good but typical science classrooms, this study focuses on how sixth graders reason about the goals and strategies of experimentation and laboratory activities in school. Collaborating with teachers, we explore whether reasoning can be deepened by developing instruction that capitalizes more effectively on the classroom opportunities that arise for fostering complex thinking and understanding. The design of the study includes (a) a baseline interview probing students' understanding of experimentation in the context of a standard, 40-min "hands-on" activity that is part of the standard sixth-grade curriculum; (b) a 3-week teaching study, in which five teachers, informed by the cognitive science research concerning the development of scientific reasoning, designed and taught a special experimentation unit in their classrooms; and (c) a series of follow-up interviews, in which students' understanding of experimentation was reexamined. The findings from the two learning contexts-one more supportive of student reasoning than the other-inform us about the kinds of reasoning that are developing in middle-school students and the forms of instruction best suited to exercising those developing skills.  相似文献

Two studies of a new science programme called WEE Science were conducted in two fifth-grade classrooms. The studies lasted for seven days in one of the classrooms and nine days in the other. At the beginning of the programme the students chose a science trade book from among the many that were selected and brought to the classroom. The students then formed groups based on the topics of the books and asked questions (Wondering) about the content. After choosing one of the 'wonderments' to pursue further, the students formed and implemented a plan for investigating (Exploring). In each classroom, each student explored, working in cooperating groups of two or more. The students then explained (Explaining) to a group of their peers what they had wondered and what and how they had explored. The students' wonderments, activities, plans, and explanations were recorded in a science notebook that had been designed for that purpose. In addition, the classrooms were videotaped while WEE Science was in progress. While the studies were successful in that most students eagerly participated in all phases of the project, some problems were encountered which created another round of wondering for the researchers. Some of these were: evaluating students' work, responding to science misconceptions of students, teaching some students to record observations in their notebooks, deciding where WEE Science would fit best in the curriculum, and anticipating its reception in the science education community.  相似文献

Throughout the history of education, debate has existed between the relative merits of instructed versus constructed knowledge. In this article, we review our program of research in science education for students with disabilities in order to reveal some insights into this debate. We review research in science curriculum, mnemonic strategies, text-processing strategies, hands-on approaches, coached elaborations, “discovery” learning, correlates of effective inclusive science classrooms, and class-wide peer tutoring with differentiated curriculum enhancements. Overall, both instructed and constructed knowledge are important and can be facilitated with appropriate instructional strategies. Implications for practice and future research are provided.  相似文献

We examined curricular orientations that graduate students in science and mathematics fields held as they experienced urban high‐school science and mathematics classrooms. We analyzed how these educators (called Fellows) saw themselves, students, teachers, schools, education, and the sense they made of mathematics and science education in urban, challenging settings in the light of experiences they brought with them into the project and experiences they designed and engaged in as they worked in classrooms for 1 or 2 years. We used Schubert's (Schubert (1997) Curriculum: Perspective, paradigm, and possibility. New Jersey: Prentice‐Hall, Inc.) four curricular orientations—intellectual traditionalism, social behaviorism, experientialism, and critical reconstructionism—to analyze the Fellows' journals, and to explore ways in which the positions they portrayed relative to curriculum, instruction, assessment, social justice, discipline, student involvement, teacher's role, subject‐matter nature, etc., shaped and were shaped by who they were before and during their classroom work. Our qualitative analysis revealed various relationships including: experientialists engaged in more open‐ended projects, relevant to students, with explicit connections to everyday‐life experiences; social behaviorists paid more attention to designing “good” labs and activities that taught students appropriate content, led them through various steps, and modeled good science and mathematics; and critical reconstructionists hyped up student knowledge and awareness of science issues that affect students' lives, such as asthma and HIV epidemic. Categorizing orientations and identifying relationships between experiences, actions, and orientations may help us articulate and explicate goals, priorities, and commitments that we have, or ought to have, when we work in urban classrooms. © 2008 Wiley Periodicals, Inc.

Recent research reveals that students' interest in school science begins to decline at an early age. As this lack of interest could result in fewer individuals qualified for scientific careers and a population unprepared to engage with scientific societal issues, it is imperative to investigate ways in which interest in school science can be increased. Studies have suggested that inquiry learning is one way to increase interest in science. Inquiry learning forms the core of the primary syllabus in Singapore; as such, we examine how inquiry practices may shape students' perceptions of science and school science. This study investigates how classroom inquiry activities relate to students' interest in school science. Data were collected from 425 grade 4 students who responded to a questionnaire and 27 students who participated in follow-up focus group interviews conducted in 14 classrooms in Singapore. Results indicate that students have a high interest in science class. Additionally, self-efficacy and leisure-time science activities, but not gender, were significantly associated with an increased interest in school science. Interestingly, while hands-on activities are viewed as fun and interesting, connecting learning to real-life and discussing ideas with their peers had a greater relation to student interest in school science. These findings suggest that inquiry learning can increase Singaporean students' interest in school science; however, simply engaging students in hands-on activities is insufficient. Instead, student interest may be increased by ensuring that classroom activities emphasize the everyday applications of science and allow for peer discussion.  相似文献

How can classrooms become communities of inquiry that connect intellectually challenging science content with language-based activities (opportunities to talk, listen, read, and write) especially in settings with diverse populations? This question guided a 3-year mixed-methods research study using the Science Writing Heuristic (SWH) approach in cooperation with 2 universities, area education agencies, 6 school districts, 32 elementary teachers, and over 700 students each year. The participating teachers engaged in a yearly summer institute, planned units, implemented this curriculum in the classroom, and contributed to ongoing data collection and analysis. Findings demonstrate that critical embedded language opportunities contribute to an increase in student Iowa Tests of Basic Skills (ITBS) scores in science and language based on level of implementation particularly for elementary students who receive free and reduced lunch (an indicator of living at the poverty level).  相似文献

The Department of Neuroscience at the University of Minnesota and the Science Museum of Minnesota have developed and implemented a successful program for middle school (grades 5-8) science teachers and their students, called Brain Science on the Move. The overall goals have been to bring neuroscience education to underserved schools, excite students about science, improve their understanding of neuroscience, and foster partnerships between scientists and educators. The program includes BrainU, a teacher professional development institute; Explain Your Brain Assembly and Exhibit Stations, multimedia large-group presentation and hands-on activities designed to stimulate student thinking about the brain; Class Activities, in-depth inquiry-based investigations; and Brain Trunks, materials and resources related to class activities. Formal evaluation of the program indicated that teacher neuroscience knowledge, self-confidence, and use of inquiry-based strategies and neuroscience in their classrooms have increased. Participating teachers increased the time spent teaching neuroscience and devoted more time to "inquiry-based" teaching versus "lecture-based teaching." Teachers appreciated in-depth discussions of pedagogy and science and opportunities for collegial interactions with world-class researchers. Student interest in the brain and in science increased. Since attending BrainU, participating teachers have reported increased enthusiasm about teaching and have become local neuroscience experts within their school communities.  相似文献

A qualitative biomechanics (functional anatomy) course is a typical course in kinesiology curriculum. Most evidence suggests that biomechanics learning could be improved with the inclusion of laboratory experiences. However, implementing laboratories into biomechanics curriculum is difficult due to cost and time constraints. This study was conducted to evaluate whether hands-on activities in lecture improve qualitative biomechanics learning. A lecture format was compared to the same course with guided and unguided hands-on activities included during lecture. Test performance and student evaluations were compared between lecture formats to determine if hands-on experiences improve learning. The hands-on group performed better on the same test questions and they evaluated their overall course activities as beneficial to their learning. The findings suggest that guided hands-on experiences may improve learning compared to unguided activities. The hands-on experiences seem to provide an embodied cognitive learning experience, facilitating retention of learned material through three-dimensional and tactile mental representations. Findings from this research are currently shaping how biomechanics is taught to students at this university and could at other universities as well.  相似文献
