Science teachers and scientific argumentation: Trends in views and practice     

Victor Sampson  Margaret R. Blanchard 《科学教学研究杂志》2012,49(9):1122-1148

Current research indicates that student engagement in scientific argumentation can foster a better understanding of the concepts and the processes of science. Yet opportunities for students to participate in authentic argumentation inside the science classroom are rare. There also is little known about science teachers' understandings of argumentation, their ability to participate in this complex practice, or their views about using argumentation as part of the teaching and learning of science. In this study, the researchers used a cognitive appraisal interview to examine how 30 secondary science teachers evaluate alternative explanations, generate an argument to support a specific explanation, and investigate their views about engaging students in argumentation. The analysis of the teachers' comments and actions during the interview indicates that these teachers relied primarily on their prior content knowledge to evaluate the validity of an explanation rather than using available data. Although some of the teachers included data and reasoning in their arguments, most of the teachers crafted an argument that simply expanded on a chosen explanation but provided no real support for it. The teachers also mentioned multiple barriers to the integration of argumentation into the teaching and learning of science, primarily related to their perceptions of students' ability levels, even though all of these teachers viewed argumentation as a way to help students understand science. © 2012 Wiley Periodicals, Inc.

Using Problem Solving to Assess Young Children’s Mathematics Knowledge     

Rosalind Charlesworth  Shirley A. Leali 《Early Childhood Education Journal》2012,39(6):373-382

Mathematics problem solving provides a means for obtaining a view of young children’s understanding of mathematics as they move through the early childhood concept development sequence. Assessment information can be obtained through observations and interviews as children develop problem solutions. Examples of preschool, kindergarten, and primary grade children’s approaches to problem solving are provided in the article. Prekindergarten and kindergarten age children discover problems during play. For example, they figure out how to use informal measurement to use construction materials such as unit blocks and Lego to build a desired building or make a desired object. Moldable materials such as clay and play dough provided shape experiences. The daily sequence of activities builds on their concept of time. Primary grade children solve adult- and child-generated problems. They may use manipulatives and/or drawings to generate problem solutions prior to using symbols and notation. Teacher and/or student devised rubrics can be used to guide evaluation.  相似文献   

Ethical issues associated with information and communication technology in counseling and guidance     

James P. Sampson Jr.  Julia Panke Makela 《International Journal for Educational and Vocational Guidance》2014,14(1):135-148

For more than 50 years, literature on the use of information and communication technology in counseling and guidance has presented ethical issues related to the development and use of technologies in practice. This paper reviews the ethical issues raised, organizing them into three categories: Social equity, resources, and services. Career professionals’ efforts to address these ethical issues are introduced via a discussion of ethical, credentialing, and accreditation standards. The article concludes with a call for additional standards development, training resources, and research to shape the use of rapidly changing technologies in ways that ethically and effectively enhance client services.  相似文献

Making the written word “speak”: Reflections on the teaching of correspondence courses     

Shirley Davis  Charles S. Elliott 《The American journal of distance education》2013,27(3):22-35

Abstract

Learning outcomes for an interactive television‐based distance learning course in introductory high school Japanese were evaluated in three successive years by comparing student achievement in the distance learning course to that in traditional classes. Year‐end achievement tests of listening and written language competency were administered to students in both the distance and face‐to‐face courses. Results in the first two years showed that test scores of students in the distance learning course were higher than those of students in the face‐to‐face classes; however, possible group differences in motivation, general ability, and experience as language learners could not be ruled out as explanations for the difference. Therefore, achievement measures were supplemented in the third year with data on students’ perceived efficacy as Japanese language users, their grades, and their previous foreign language learning experience. The achievement data again showed differences favoring the distance learning group; trends were consistent for students with differing levels of school success and amount of prior language learning experience. Factors that could account for these results are hypothesized and suggestions for future research are proposed.  相似文献   

Embedded Assessment in Project‐based Science Courses for the Gifted: Insights to inform teaching all students     

Shirley Miedijensky  Tali Tal 《International Journal of Science Education》2013,35(18):2411-2435

The present study of gifted students’ views of assessment is aimed at understanding how the employment of Embedded Assessment for Learning (EAfL) framework in science courses for the gifted affects the students’ views throughout the learning process. The participants were 86 students in three programmes for the gifted who elected project‐based science courses. The data included questionnaires, distributed at the beginning and at the end of the assessment processes in each science course, and in‐depth interviews with 12 students, which were analysed according to three main themes: general view of assessment; assessment modes; and relationships between assessment and learning. The students viewed the EAfL framework as an integral part of the learning process, and perceived it as a means of expressing autonomous learning and a range of performances; characteristics that correspond with the students’ unique needs. In addition, students addressed cognitive and social processes they had undergone. This implies that assessment which is explicitly designed to promote learning in science courses is a powerful tool for teachers as well as for students, and contributes to meaningful learning.  相似文献   

An end of innocence: African-American high school protest in the 1960s and 1970s     

John L. Rury  Shirley Hill 《History of education》2013,42(4):486-508

This paper considers African-American student protests in secondary schools during the 1960s and early 1970s. Taking a national perspective, it charts a growing sense of independence and militancy among black students as they made the schools a focal point of activism. Activist students challenged established civil rights organisations on a variety of questions. They also engaged in an escalating series of protest activities to make schools change. Much of this focused on curricular change, particularly adding black history courses and hiring African-American teachers and principals. Generally, these protests proved quite successful. Black students also protested against conditions encountered in integrated schools, where they often met hostility from whites. Distinct regional patterns characterised such activities, with more protest over school issues in the North and greater conflict regarding desegregation in the South. By the mid-1970s the era of black secondary student protest concluded, although its legacy continues to live.  相似文献
