This study compares work time data collected by the German Time Use Survey (GTUS) using the diary method with stylized work time estimates from the GTUS, the German Socio-Economic Panel, and the German Microcensus. Although on average the differences between the time-diary data and the interview data is not large, our results show that significant…

The authors make a case for using wiki technology in qualitative research. A wiki is an online database that allows users to create, edit, and/or reflect on the content of a web page. Thus, wiki technology can support qualitative research that attempts to understand the shared thinking of participants. To illustrate the use of the wiki for this…

The mathematics of information processing and the Internet can be organized around four fundamental themes: (1) access (finding information easily); (2) security (keeping information confidential); (3) accuracy (ensuring accurate information); and (4) efficiency (data compression). In this article, the author discusses each theme with reference to…

In the following pages, we examine some common methodological challenges in educational technology research and highlight new data collection approaches using examples from the literature and our own work. Given that surveys and questionnaires remain widespread and dominant tools across nearly all studies of educational technology, we first…

Piezoelectric actuators (or piezoactuators) are known for their nanoresolution and high-speed positioning capabilities. Therefore, they are used in scanning probe microscopes and in the design of innovative surgical tools and biomedical devices. The expected growth of engineering jobs in the nano- and bio-related fields, in which piezoactuators…

Decentralization in the education system has become a trend in many developing countries. However, it is not a solution to the many problems in education faced by these countries. One of the adverse effects of decentralization is disparity between regions or schools in terms of educational achievement. This paper offers a justification for such a…

Cell water relationships are important topics to be included in cell biology courses. Differences exist in the control of water relationships in plant cells relative to control in animal cells. One important reason for these differences is that turgor pressure is a consideration in plant cells. Diffusion and osmosis are the underlying factors…

Purpose: The American Speech-Language-Hearing Association's (ASHA's) National Outcomes Measurement System (NOMS) was developed in the late 1990s. The primary purpose was to serve as a source of data for speech-language pathologists (SLPs) who found themselves called on to provide empirical evidence of the functional outcomes associated with their…

The purpose of this study is to determine how to build a democratic classroom in terms of teachers' views. In this study, the qualitative research technique is applied. In addition, the semi-structured interview technique is used as a method of data collection. The data obtained are coded into Nvivo2 and then the following themes are established:…

Both the National Science Education Standards (NSES) and the National Council of Teachers of Mathematics (NCTM) recommend appropriately incorporating mathematics into other disciplines (NRC 1996; NRC 2003; NCTM 2000). With this in mind, an interdisciplinary, inquiry-based project was undertaken to incorporate mathematical analysis of data into a…

This report presents findings on the numbers and types of public elementary and secondary local education agencies (LEAs) in the United States and other jurisdictions in the 2007-08 school year, using data from the Local Education Agency Universe Survey of the Common Core of Data (CCD) survey system. The CCD is an annual collection of data that…

There are multiple ways to gather information from families receiving early intervention services (J. J. Woods & D. P. Lindeman, 2008). In this article, we discuss a specific strategy for doing this through information-gathering conversations with families. The routines-based interview (RBI; R. A. McWilliam, 1992, 2005a) was developed to meet a…

This article has three goals. The first goal is to clarify the role that the consequences of test score use play in validity judgments by reviewing the role that modern writers on validity have ascribed for consequences in supporting validity judgments. The second goal is to summarize current views on who is responsible for collecting evidence of…

The concept of "teacher quality" has undergone a profound transformation in the last decade. Through the late 1990s, most policymakers assumed that educator effectiveness was immeasurable and that our only hopes to increase it were tied to classroom experience and academic credentials. Yet since 2001, through a series of notable research…

In times of economic uncertainty, community colleges have consistently turned to the experience of past generations as an avenue toward innovation and the modernization of their programs and services. Community colleges have been able to continuously reinvent themselves to serve the ever-changing needs of society. With President Obama's increased…
