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…

This article explores how concept maps and mind maps can be used as data collection tools in mixed methods research to combine the clarity of quantitative counts with the nuance of qualitative reflections. Based on more traditional mixed methods approaches, this article details how the use of pre/post concept maps can be used to design qualitative…

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 the United States Department of Education's (the Department) Fiscal Year (FY) 2017 "Agency Financial Report" (AFR) is to inform Congress, the President, other external stakeholders, and the American people on how the Department used the federal resources entrusted to it to promote student achievement and preparation for…

In the first part of this dissertation, I document wiki usage in U.S. K-12 settings by analyzing data on a representative sample drawn from a population of nearly 180,000 wikis. My research group, which I lead and managed, measured the opportunities wikis provide for students to develop 21st century skills such as expert thinking, complex…

For years California has been a leader in public education. In 1999, the state implemented some of the strongest content standards in the country through its main accountability metric, the Academic Performance Index (API). The state has also signed onto the Common Core State Standards, taking important steps to ensure its students are college-…

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…

National Assessment of Educational Progress (NAEP) has expended considerable effort to ensure high quality in data collection by developing standardized materials and survey operation procedures and using well-trained professional administrators. However, schools are allowed to minimize the disruption associated with pulling students out of…

Students should have exposure to social justice education (SJE) through the content-based curriculum or through cocurricular learning opportunities. This program evaluation study used qualitative data collection and analysis procedures to determine how to best improve the cocurricular SJE program, Lead for Diversity (LFD), which is used in high…

The Common Core of Data (CCD) nonfiscal surveys consist of data submitted annually to the National Center for Education Statistics (NCES) by state education agencies (SEAs) in the 50 states, the District of Columbia, Puerto Rico, the four U.S. Island Areas (American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the U.S. Virgin…

We develop an Easy Java Simulation (EJS) model for students to experience the physics of idealized one-dimensional collision carts. The physics model is described and simulated by both continuous dynamics and discrete transition during collision. In designing the simulations, we discuss briefly three pedagogical considerations namely (1) a…

Predicting the future is now in the hands of K12 administrators. While for years districts have collected thousands of pieces of student data, educators have been using them only for data-driven decision-making or formative assessments, which give a "rear-view" perspective only. Now, using predictive analysis--the pulling together of data over…
