This study examined how specific guidelines and heuristics have been used to identify methodological rigor associated with single‐case research designs based on quality indicators developed by Horner et al. Specifically, this article describes how literature reviews have applied Horner et al.'s quality indicators and evidence‐based criteria. Ten literature reviews were examined to ascertain how literature review teams (a) used the criteria recommended by Horner et al. as meeting the 5‐3‐20 evidence‐based practice (EBP) thresholds (five studies conducted across three different research teams that include a minimum of 20 participants) to assess single‐case methodological rigor; and (b) applied the 5‐3‐20 thresholds to determine whether the independent variables reviewed qualified as potential effective practices. The 10 literature reviews included 120 single‐case designs. This study found that 33% of the reviewed single‐case designs met Horner et al.'s quality indicator criteria. Three of the literature reviews concluded that examined practices met criteria to qualify as an EBP. Recommendations related to quality indicator criteria and EBP established by the literature review teams as well as directions for future research are discussed.  相似文献

Abstract

In this article, we share a model of flipped instruction that allowed us to gain a window into our students’ mathematical thinking. We depict how that increased awareness of student thinking shaped our mathematics instruction in productive ways. Drawing on our experiences with students in our own classrooms, we show how flipped instruction can be used to design experiences that help students make sense of mathematics during class sessions.  相似文献

The Franklin Institute, Philadelphia, Pennsylvania, awards the 2010 Benjamin Franklin Medal in Computer and Cognitive Science to Professor Shafrira Goldwasser for fundamental work contributing to the theoretical foundation of modern cryptography and leading to techniques that mathematically guarantee secure access to the internet. More precisely, she is recognized for key contributions in provable security and in particular for interactive and zero-knowledge proofs and their application to cryptography and complexity theory.  相似文献

Intermediation and the role of intermediaries in innovation   总被引:5,自引:0,他引:5  
This paper investigates the issue of intermediation and the role of intermediaries in the innovation process. The aim of this paper is three-fold. Firstly, to review and synthesis the literature in this field; from this to develop a typology and framework of the different roles and functions of the intermediation process within innovation; lastly to try and operationalise the typology within the context of UK using case study material.  相似文献

Objectives of a project-oriented mechanical engineering course, Engineering Design, were achieved through a design project, where students designed, built and demonstrated an extreme version of a basic Theo Jansen device. Through this project, junior students in the University of Louisiana fully developed the capability of applying mathematic and kinematic knowledge in the analysis and design of mechanisms. Students also developed oral and written communication skills, which would be used in design environments, through the presentation of results in both oral and written forms. An assessment of the design project indicated that effective teaching and learning spread through the semester, with the junior students acting as project managers and experiencing design practices. An example of a student-designed Theo Jansen device is presented in this paper to show the study results achieved by the students.  相似文献

There have been a number of earlier investigations, using differing methodologies, into the extent to which teachers in the secondary school interact with boys and girls and the results have suggested an imbalance in the teachers’ verbal behaviour towards the genders that is quite similar to the imbalance found in teachers’ behaviour in the primary school. The main aim of this study was to devise an investigation using the same methodology as that used in a recent primary school investigation in order to be able to make a fair comparison between the two levels. The results showed considerable differences in the teachers’ verbal behaviour towards the genders in the secondary school from that of teachers in the primary school. Where the primary school data showed teachers interacting more with the boys than the girls and the boys being less on‐task than the girls, the secondary school data showed no such differences.  相似文献
