This paper reports the effect of continuous summative assessment on the behaviour and learning environment of students. Assessing the performance of students is considered to be the most important thing a teacher can do for their students and it can have a profound effect on their learning. Continuous summative assessment was introduced as a form of assessment on a module within an undergraduate degree at a UK university. Student perceptions of the process were sought via a questionnaire and interviews. The paper describes the effect the assessment had on student motivation, their approach to learning and the change to their learning environment. The conclusion reached is that while continuous summative assessment may be time‐consuming to administer, the rewards of an enhanced learning environment for students outweigh the additional burden on staff. The results should be of interest to those academics who are concerned with assessment and its impact on behaviour.  相似文献

Teachers need more clarity about effective teaching practices as they strive to help their low-achieving students understand mathematics. Our study describes the instructional practices used by two teachers who, by value-added metrics, would be considered “highly effective teachers” in classrooms with a majority of students who were English learners. We used quantitative data to select two fifth-grade classrooms where students, on average, made large gains on a mathematics achievement test, and then examined teaching practices and contextual factors present in each classroom. Participants included two teachers from a mid-Atlantic district and their students who were 67% English learners and 68% economically disadvantaged. We found that the use of multiple representations of mathematics concepts, attention to vocabulary building, individual and group checks for understanding and error analysis were prevalent practices in both high gains classrooms. Also, class sizes ranged from 12–19 students. Discussion focuses on whether observed practices are aligned with recommended teaching practices for English learner students.  相似文献

Simulations on computers can allow many experiments to be conducted quickly to help students develop an understanding of statistical topics. We used a simulation of a challenging problem in statistics as the focus of an exploration of situations where members of a problem‐solving group are physically separated then reconnected via combinations of computer and communications technology to work collaboratively on the simulation. The particular focus in this work was on trying to understand how students could use a system which allowed them to conduct variable based practical experiments in order to help them develop their knowledge and understanding of a statistics topic. We wished to develop an understanding of the virtual space created by shared simulations and video communication tools for supporting collaborative work between people at a distance. The paper reports on an experiment involving 48 subjects using this virtual space to establish the impact on their statistics understanding and to map their use of this distributed environment for learning. It establishes that the virtual space is effective for learning, and that the video conferencing condition which allows for eye contact between the pairs has some advantages for successful problem‐solving with the simulation. In addition the experimental setting provided some opportunities for exploring subjects' understanding of statistical and experimental concepts.  相似文献

Third, fifth, and seventh graders, most of them Mexican-American, were exposed to an empirically based and culturally sensitive AIDS curriculum designed to replace their intuitive theories with a coherent, scientific account of the causal processes that lead from risk behavior to AIDS symptomatology. Compared to students in control classes, experimental students knew more about AIDS risk factors and AIDS generally, displayed more conceptual understanding of the causes of AIDS and flu, and were more willing to interact with people who have AIDS (although not less worried about AIDS) at posttest and typically at follow-up 10–11 months later. The findings point to the potential value of adopting an intuitive theories approach in assessing and modifying children's concepts of health and illness and suggest, contrary to Piagetian formulations, that even relatively young children can, with appropriate instruction, grasp scientific theories of disease.  相似文献

Conclusion The goals of this project were to design and implement a series of courses that would better prepare elementary school teachers to teach science and would promote positive attitudes toward science and science teaching. The initial offering of the first series of courses met with moderate success. Although the courses fostered an increase in cognitive knowledge, the magnitude of the improvement was not what we had anticipated. There was no significant improvement in the attitudes of the students toward science or science teaching. The science course has been revised and is currently being offered for both preservice and inservice teachers. The revisions include lengthening the class time, so that the material can be covered at a more relaxed pace, and increasing the amount of active team teaching by the instructors to further emphasize the interrelations between chemistry and biology and to eliminate the fragmentation of the course. It is hoped that these changes will also have a positive impact on the students’ attitudes toward the course and thus toward science in general.  相似文献

This article introduces a new international model that focuses on culture while including familiar elements of human performance technology (HPT). HPT adaptation for cultural differences is an essential part of our profession. We must be sensitive and flexible to succeed in an ever‐changing global environment.  相似文献

In the current UK policy context increased attention is being given to the use of continuing professional development (CPD) as a mechanism for reforming and redefining the professionalism of teachers in the schools' sector. This, in turn, has focused attention on measuring the impact of professional development on practice and, in particular, pupil outcomes. This is a difficult task even where a CPD initiative is focused on changing classroom practice. It becomes even more difficult where programmes focus on the development of school leaders and managers. Nor does measuring impact, in itself a thorny issue, necessarily help us to understand why and how experienced practitioners change their practice. Without some further understanding of what 'impact' entails and the processes involved in achieving it we are unlikely to move further forward in designing and providing effective learning opportunities for serving teachers.  相似文献

In putting together the NASIG strategy session “Cooperative Trends in Digital Archiving,” the three panelists, Daviess Menefee (Elsevier), Eileen Fenton (Portico), and Marilyn Geller (Lesley University), discussed issues they faced in their own organizations. All three panelists shared concerns about the need for archiving in general and for archiving born digital journals specifically, and about core organizational values that led them to pursue digital archiving. They had common concerns about who should be involved in digital archiving projects and how it should be accomplished. There were some interesting parallels in the decision making process within each organization. In this presentation, each of the panelists discussed how and why they came to their decisions, and how they all relied on the CLIR report, E-Journal Archiving Metes and Bounds, 1 1.
