The National Research Council’s Framework for K-12 Science Education and the Next Generation Science Standards (NGSS Lead States in Next Generation Science Standards: For states, by states. The National Academies Press, Washington, 2013) move teaching away from covering many isolated facts to a focus on a smaller number of disciplinary core ideas (DCIs) and crosscutting concepts that can be used to explain phenomena and solve problems by engaging in science and engineering practices. The NGSS present standards as knowledge-in-use by expressing them as performance expectations (PEs) that integrate all three dimensions from the Framework for K-12 Science Education. This integration of core ideas, practices, and crosscutting concepts is referred to as three-dimensional learning (NRC in Division of Behavioral and Social Sciences and Education. The National Academies Press, Washington, 2014). PEs state what students can be assessed on at the end of grade level for K-5 and at the end of grade band for 6–8 and 9–12. PEs do not specify how instruction should be developed nor do they serve as objectives for individual lessons. To support students in developing proficiency in the PEs, the elements of the DCIs will need to be blended with various practices and crosscutting concepts. In this paper, we examine how to design instruction to support students in meeting a cluster or “bundle” of PEs and how to blend the three dimensions to develop lesson level PEs that can be used for guiding instruction. We provide a ten-step process and an example of that process that teachers and curriculum designers can use to design lessons that meet the intent of the Next Generation of Science Standards. 相似文献

Background:Literature searches underlie the foundations of systematic reviews and related review types. Yet, the literature searching component of systematic reviews and related review types is often poorly reported. Guidance for literature search reporting has been diverse and, in many cases, does not offer enough detail to authors who need more specific information about reporting search methods and information sources in a clear, reproducible way. This document presents the PRISMA-S (Preferred Reporting Items for Systematic reviews and Meta-Analyses literature search extension) checklist, and explanation and elaboration.Methods:The checklist was developed using a three-stage Delphi survey process, followed by a consensus conference and public review process.Results:The final checklist includes sixteen reporting items, each of which is detailed with exemplar reporting and rationale.Conclusions:The intent of PRISMA-S is to complement the PRISMA Statement and its extensions by providing a checklist that could be used by interdisciplinary authors, editors, and peer reviewers to verify that each component of a search is completely reported and, therefore, reproducible. 相似文献

AbstractEnglish-only college education in non-English speaking countries is a rapidly growing phenomenon that has been dubbed as the most important trend in higher education internationalization. Despite worldwide popularity, there is little empirical evidence about how the transition to English-only instruction affects students’ academic outcomes. Using a natural experiment at a selective university in Central Asia and a difference-in-differences strategy, we estimate the causal effect of switching to English-only instruction on students’ college outcomes. We find that the introduction of English-only instruction led to a decrease of GPAs and probability of graduation and an increase in the number of failed course credits. Although negative, the effects were short-lived. The difference-in-differences estimates and the examination of potential mechanisms suggest that at least in selective universities in non-English speaking countries, the switch to English-only instruction may affect college outcomes negatively at the time of transition but may not necessarily imply longer-run negative effects. 相似文献

Peace education has been recognized as an important aspect of social education for the past three decades. The critical literature
as well as official documents, however, have given little attention to its philosophical foundations. This essay explores
these foundations in the ethics of (1) virtue, (2) consequentialism, (3) aesthetics, (4) conservative politics and (5) care.
Each of these alone composes a significant element of peace education, although ultimately its solid basis can only be established
through an integrative approach encouraging a culture of peace. The more complete development and articulation of the philosophical
rationale of peace education is yet to be accomplished and remains a task for the future. 相似文献

The confluence theory, which hypothesizes a relationship between intellectual development birth order, and family size, was examined in a colombian study of more than 36,000 college applicants. The results of the study did not support the confluence theory. The confluence theory states that the intellectual development of a child is related to average mental age of the members of his family at the time of his birth. The mental age of the parents is always assigned a value of 30 and siblings are given scores equivalent to their chronological age at the birth of the subject. Therefore, the average mental age of family members for a 1st born child is 30, or 60 divided by 2. If a subject is born into a family consisting of 2 parents and a 6-year old sibling, the average mental age of family members tends, therefore, to decrease with each birth order. The hypothesis derived from the confluence theory states that there is a positive relationship between average mental age of a subject's family and the subject's performance on intelligence tests. In the Colombian study, data on family size, birth order and socioeconomic status was derived from college application forms. Intelligence test scores for each subject was obtained from college entrance exams. The mental age of each applicant's family at the time of the applicant's birth was calculated. Multiple correlation analysis and path analysis were used to assess the relationship. Results were 1) the test scores of subjects from families with 2,3,4, and 5 children were higher than test scores of the 1st born subjects; 2) the rank order of intelligence by family size was 3,4,5,2,6,1 instead of the hypothesized 1,2,3,4,5,6; and 3) only 1% of the variability in test scores was explained by the variables of birth order and family size. Further analysis indicated that socioeconomic status was a far more powerful explanatory variable than family size. 相似文献

This paper examines some instructional practices concerning the non‐optimal uses of video, films and other mass media in the K–12 classroom. Based on a six‐year process of observing and interviewing teachers regularly in two school districts in Massachusetts, USA, this paper presents a typology of seven common patterns of non‐optimal media use, instructional practices that diminish or weaken the value of film and video viewing as a learning tool. A telephone survey was conducted with a purposive sample of 130 middle‐school and high‐school teachers to provide additional evidence concerning teacher perceptions of the frequency of their colleagues' non‐optimal use of video. Teachers in the USA report that their colleagues frequently use media for non‐educational purposes, including to fill time, to keep students quiet, as a break from learning, or as a reward for good behavior. The implications of non‐optimal media use are considered in light of renewed interest in integrating media literacy into K–12 instruction. 相似文献

US school libraries are required to ensure that schoolchildren and school staff with disabilities have equal opportunity to use and benefit from library facilities and information services under federal law. However, evidence indicates teacher‐librarians (TLs) often lack the training, knowledge and skills to provide programmes and services that meet the needs of students with disabilities. Project ENABLE (Expanding Nondiscriminatory Access by Librarians Everywhere) was created to respond to this shortfall by designing, implementing and evaluating a professional development programme in New York State. The project applies a social model of disability to help 100 TLs, special educators and general educators further develop their skills and resources by teaming together to create an inclusive environment for all students. This is achieved through the use of universal design principles, appropriate assistive and other technologies, an emphasis on person‐first language and sensitivity simulations, a focus on inclusive lesson planning, and by developing collaboration capacity among participant teams. Curriculum development, data collection and analyses are presented. The effect of the Project ENABLE trainings was significant in terms of higher levels of skill and knowledge reported by participants for creating accessible library programmes, advancing inclusive education and building effective collaborations. Drawing from their workshop learning and resources, participant teams developed action plans to implement during the 2011–2012 school year. This project underscores the importance of TLs in the education of all students, including those with disabilities. Higher education and local professional development programmes must place greater emphasis on preparing TLs to perform this role effectively and confidently. 相似文献

In this report, we adapt and extend a methodology for documenting the collective production of meaning in a classroom community.
A cornerstone of the methodological approach that we develop is a close examination of classroom discourse. Our efforts to
analyze the collective production of meaning by examining classroom interaction are compatible with the relatively recent
emphasis in mathematics and science education research that focuses on how communities of learners establish ideas through
discourse and inquiry. The methodological approach we take builds on and extends an approach from mathematics education that
uses Toulmin’s argumentation model to document and analyze students’ conceptual progress. Our modification introduces a new
criterion for empirically demonstrating when particular ways of reasoning become part of the normative practices of the community.
An example from an undergraduate course in physical chemistry is used to illustrate the methodology. 相似文献
