The improvement of science education in accord with the current science reform agenda requires the development of sophisticated instructional strategies that are grounded in a clear recognition of student understanding. We describe a pedagogical strategy, the assessment conversation, that helps teachers elicit student understanding and then use elicited and diverse student understanding as the instructional basis for achieving conceptual and reasoning goals in the classroom. We then illustrate the potential and challenges of using the assessment conversation through examples that have emerged from Science Education through Portfolio Instruction and Assessment (SEPIA), a project attempting to reform practices of assessment and instruction in middle school science classrooms. We conclude with a discussion of issues facing any substantial reform of science education.  相似文献

This mixed methodology action research study examined the impact of a curricular innovation designed to provide an authentic science inquiry learning experience for 15 secondary science teacher candidates enrolled in a master’s level initial certification program. The class investigated the question “How can peak autumn color in New England be determined?” The project goals were to help teacher candidates acquire the skills, knowledge, and dispositions necessary to foster learning through inquiry in their respective content areas as defined by teacher preparation professional standards. Though the teacher candidates were successful at identifying a likely answer to the question, the project failed to achieve its learning goals. Reasons for the project’s failure and implications for the science education community are discussed.  相似文献

Social work programs undertake to educate competent professionals and to promote critical thinking among students who are expected to become lifelong learners. In addition, programs are called on to develop reliable and valid measures for assessing student learning outcomes and to use assessment results to reflect upon and strengthen curriculum. This study explores the use of a graduate integrative seminar to accomplish these goals. The authors describe the learning and assessment processes of the seminar. The authors used a mixed-method research design to analyze data from students over a 3-year period regarding the effectiveness of the seminar as well as from graduate faculty regarding student achievement of curricular objectives. Results indicate that formative assessment processes promote student learning in a manner that mobilizes students to strive for excellence, and that an embedded measure of learning outcomes in the form of a final integrative project may serve as a rigorous assessment tool.  相似文献

Throughout the United States, various summer science programs for precollege students are conducted with an aim toward increasing the involvement of young people in science. Most of these programs are perceived as successful by teachers and scientists because they involve students in hands-on science activities, improve their scientific skills and confidence, and allow them the opportunity to use science to answer questions and solve problems. The work described here involves a detailed assessment of a summer National Science Foundation (NSF) Young Scholars Program, which was carried out over 2 summers. Student participants were entering 9th and 10th grade. The data used for this assessment included journals kept by teaching assistants, questionnaires administered to the participants and parents, and interviews with the participants. Analysis revealed that students perceived program success differently from teachers and program organizers. Their perception of the success of a program is directly related to whether or not their individual research project met its goals, regardless of other project activities. Designing projects that have a high likelihood of success from this perspective can be complex, but this work identified six variables that must be incorporated appropriately into the design of a project to ensure its success: (1) extent of project structure and who structures the project, faculty or student; (2) project relevance; (3) project flexibility; (4) project background research; (5) tangible results; and (6) project introduction.  相似文献

Needs assessment is a systematic and systemic process intended to identify and define gaps between current performance and desired performance. Needs assessments are most beneficial if they address issues that affect successful accomplishment of operational or tactical processes as well as outcomes that allow an organization to meet its overall strategic goals. A team of graduate students took on a needs assessment project to ascertain the causes of declining accuracy in a key task in an aerospace manufacturing process. The project encountered numerous barriers within the client organization, but the team systematically applied human performance technology methods in multiple stages to gather and analyze the available data. The end result was a set of identified root causes and recommended interventions focused on improving performance.  相似文献

The National Committee on Science Education Standards and Assessment (1994 draft) viewed several science processes as important to an understanding of science as inquiry: formulating usable questions, planning experiments, conducting systematic observations, interpreting and analyzing data, drawing conclusions, communicating, and coordinating and implementing a full investigation. This study is one of three undertaken to develop research rubrics for a performance assessment of science processes and to evaluate seventh-grade science students' ability to perform them. Specifically, this article focuses on the processes of recording data, analyzing data, drawing conclusions, and providing evidence. A total of 364 students field tested the Alternative Assessment of Science Process Skills. Their responses were used to develop a research rubric, and then this rubric was used to determine response patterns that could inform both instruction and assessment of science process skills. Only 61% of students performed the activity and recorded data successfully. Sixty-nine percent of students did not attend to the hypothesis in drawing their conclusions. Eighty-one percent did not provide specific evidence for their conclusions. These results were discussed in light of relevant theories and models as well as their implications for instruction and assessment. © 1996 John Wiley & Sons, Inc.  相似文献

In this article, we compare two recent university reform projects: the Korean Brain Korea 21 project and the German Universities Excellence Initiative. We describe and compare both projects’ goals, selection processes, and preliminary outcomes. While the Korean project is characterized by a relatively high level of political intervention and can be seen as mainly a human resources development program with clearly defined strategic goals, the German tradition of university autonomy is also reflected in the reform project analyzed here. The project goal is more vaguely defined for the German project, but lies mainly in the field of research capacity building. Another key difference is the time horizons in both projects and the resulting incentives for publication and chosen research projects: while the Korean projects are evaluated on a yearly basis, the German projects have a longer time horizon for evaluation. A preliminary evaluation shows that both programs have succeeded in increasing publication output in the respective countries. However, an analysis of the quality of the new publications by, for example, their citation numbers, remains to be done in the future.  相似文献

Differential item functioning (DIF) analyses are a routine part of the development of large-scale assessments. Less common are studies to understand the potential sources of DIF. The goals of this study were (a) to identify gender DIF in a large-scale science assessment and (b) to look for trends in the DIF and non-DIF items due to content, cognitive demands, item type, item text, and visual-spatial or reference factors. To facilitate the analyses, DIF studies were conducted at 3 grade levels and for 2 randomly equivalent forms of the science assessment at each grade level (administered in different years). The DIF procedure itself was a variant of the "standardization procedure" of Dorans and Kulick (1986) and was applied to very large sets of data (6 sets of data, each involving 60,000 students). It has the advantages of being easy to understand and to explain to practitioners. Several findings emerged from the study that would be useful to pass on to test development committees. For example, when there was DIF in science items, MC items tended to favor male examinees and OR items tended to favor female examinees. Compiling DIF information across multiple grades and years increases the likelihood that important trends in the data will be identified and that item writing practices will be informed by more than anecdotal reports about DIF.  相似文献

Designed-based research principles guided the study of 51 secondary-science teachers in the second year of a 3-year professional development project. The project entailed the creation of student-centered, inquiry-based, science, video games. A professional development model appropriate for infusing innovative technologies into standards-based curricula was employed to determine how science teacher’s attitudes and efficacy where impacted while designing science-based video games. The study’s mixed-method design ascertained teacher efficacy on five factors (General computer use, Science Learning, Inquiry Teaching and Learning, Synchronous chat/text, and Playing Video Games) related to technology and gaming using a web-based survey). Qualitative data in the form of online blog posts was gathered during the project to assist in the triangulation and assessment of teacher efficacy. Data analyses consisted of an Analysis of Variance and serial coding of teacher reflective responses. Results indicated participants who used computers daily have higher efficacy while using inquiry-based teaching methods and science teaching and learning. Additional emergent findings revealed possible motivating factors for efficacy. This professional development project was focused on inquiry as a pedagogical strategy, standard-based science learning as means to develop content knowledge, and creating video games as technological knowledge. The project was consistent with the Technological Pedagogical Content Knowledge (TPCK) framework where overlapping circles of the three components indicates development of an integrated understanding of the suggested relationships. Findings provide suggestions for development of standards-based science education software, its integration into the curriculum and, strategies for implementing technology into teaching practices.  相似文献

Higher education is becoming a major driver of economic competitiveness in an increasingly knowledge-driven global economy. Maintaining the competitive edge has seen an increase in public accountability of higher education institutions through the mechanism of ranking universities based on the quality of their teaching and learning outcomes. As a result, assessment processes are under scrutiny, creating tensions between standardisation and measurability and the development of creative and reflective learners. These tensions are further highlighted in the context of large undergraduate subjects, learner diversity and time-poor academics and students. Research suggests that high level and complex learning is best developed when assessment, combined with effective feedback practices, involves students as partners in these processes. This article reports on a four-phase, cross-institution and cross-discipline project designed to embed peer-review processes as part of the assessment in two large, under-graduate accounting classes. Using a social constructivist view of learning, which emphasises the role of both teacher and learner in the development of complex cognitive understandings, we undertook an iterative process of peer review. Successive phases built upon students’ feedback and achievements and input from language/learning and curriculum experts to improve the teaching and learning outcomes.  相似文献

A challenge for urban systemic reform initiatives in science education has been to achieve local, state, and national standards for teaching and learning. We have collaborated with teachers in the Detroit Public School System to design project‐based curriculum materials that contextualize the learning of science in meaningful real‐world problems, engage students in science inquiry, and use learning technologies. We present a sixth grade project‐based science unit in which students explored the driving question “How Do Machines Help Me Build Big Things?” and address the science learning goals of balanced and unbalanced forces, simple and complex machines, and mechanical advantage. Twenty‐four teachers and over 2500 students in Detroit participated in enactments of this project over 4 years. Student learning outcomes were determined for the three learning goals and inquiry process skills using pre‐ and postachievement tests. Achievement outcomes as measured by the pre/posttest show significant and consistently high learning gains, even as participation in the project increased to include greater numbers of teachers and students in successive enactments, and leadership of the professional development support for this project transitioned from university researchers to district teacher leaders. These results illustrate that materials which contextualize learning and support student inquiry as part of an urban systemic reform effort can promote learning of important and meaningful science content aligned with standards. © 2004 Wiley Periodicals, Inc.

Assessment can be conducted in various ways in school, and has also different purposes. In this paper the focus is on pupil assessment during project work. The article touches on the aim of assessment that has ranking and certificating purposes, but its main focus is on assessment as a learning device. Dialogues from the classroom are used as illustrations of authentic assessment that takes place during the work processes. These dialogues show that assessment is conducted by the teacher, by the pupils of each other and the pupils of themselves. The paper ends with a discussion bringing the assessment discussion further by focusing on criteria and goals as important ingredients in the assessment processes.  相似文献

Professional Learning Communities (PLCs) are frequently being used as a vehicle to transform science education. This study explored elementary teachers' perceptions about the impact of participating in a science PLC on their own professional development. With the use of The Science Professional Learning Communities Survey and a semi-structured interview protocol, elementary teachers' perceptions of the goals of science PLCs, the constraints and benefits of participation in PLCs, and reported differences in the impact of PLC participation on novice and experienced teachers were examined. Sixty-five elementary teachers who participated in a science PLC were surveyed about their experiences, and a subsample of 16 teachers was interviewed. Results showed that most of the teachers reported their science PLC emphasized sharing ideas with other teachers as well as working to improve students' science standardized test scores. Teachers noted that the PLCs had impacted their science assessment practices as well as their lesson planning. However, a majority of the participants reported a differential impact of PLCs depending on a teacher's level of experience. PLCs were reported as being more beneficial to new teachers than experienced teachers. The interview results demonstrated that there were often competing goals and in some cases a loss of autonomy in planning science lessons. A significant concern was the impact of problematic interpersonal relationships and communication styles on the group functioning. The role of the PLC in addressing issues related to obtaining science resources and enhancing science content knowledge for elementary science teachers is discussed.  相似文献

The purpose of this study was to understand what personal epistemologies and science teaching goals preservice secondary science teachers of a teacher education program in the USA bring with them to their learning to teach and how they translate such beliefs into actions. A set of essay questions, developed through a pilot study, was used to identify preservice teachers’ personal epistemologies and teaching goals at the beginning of science methods instruction. Classroom observation reports, video recorded teaching episodes, lesson plans and self-video reflections were collected to identify connections between their epistemologies, teaching goals, and practice of teaching. Relational and ontological dimensions of epistemological beliefs were found to be useful for understanding preservice teachers’ personal epistemologies and teaching practices. The data suggests that the participants’ espoused teaching goals were relevant to their personal epistemologies when differentiating naïve personal epistemologies from the sophisticated, and their emerging teaching practices demonstrated shifts in personal epistemologies and potential for further development in teaching practices. Findings indicate sources of how teaching practices are shaped. Implications for teacher education include needs for addressing ways to deal with teaching constraints for constructivist teaching approaches, collaboration with content course instructors, critical reflection on field experience, and developing induction programs that support continuing development of emerging teaching practices.  相似文献

This case study examines ideas on a thinking curriculum and learning to learn in the context of secondary education, by exploring one subject area- computing studies- at the Scottish secondary 3/4 (S3/S4) level with 14- to 16-year-olds. The infusion approach used in this project combines direct teaching on problem solving strategies, modeling of solution processes, on-going formative assessment, and developing metacognition through processes of reflection, articulation and exploration. The case study provides an example of how these approaches can be interweaved within a problem-based learning methodology for teaching computer programming at an introductory level. The study demonstrates how an appropriate balance can be struck between content objectives and broader educational goals within an infusion approach, resulting in the achievement of successful learning outcomes. Extending the approach to other subject domains could greatly enhance the connectedness of the secondary curriculum, thus enabling students to learn more efficiently. This would require cross-curricular collaborations and a reformulation of existing curricula.  相似文献

BIO2010 advocates enhancing the interdisciplinary, mathematics, and physical science components of the undergraduate biology curriculum. The Department of Chemistry and Life Science at West Point responded by developing a required physical chemistry course tailored to the interests of life science majors. To overcome student resistance to physical chemistry, students were enabled as long-term stakeholders who would shape the syllabus by selecting life science topics of interest to them. The initial 2 yr of assessment indicates that students have a positive view of the course, feel they have succeeded in achieving course outcome goals, and that the course is relevant to their professional future. Instructor assessment of student outcome goal achievement via performance on exams and labs is comparable to that of students in traditional physical chemistry courses. Perhaps more noteworthy, both student and instructor assessment indicate positive trends from year 1 to year 2, presumably due to the student stakeholder effect.  相似文献
