Automatic item generation represents a relatively new but rapidly evolving research area where cognitive and psychometric theories are used to produce tests that include items generated using computer technology. Automatic item generation requires two steps. First, test development specialists create item models, which are comparable to templates…

This article discusses audience responses to a children's soap opera produced and broadcast in Kenya. It examines the evaluation process in relation to qualitative audience research within Cultural Studies. It challenges an Entertainment-Education model of media as vehicles for messages and links strongly with Communication for Social Change…

For a period, in the run up to the election (2007-2008) and the months after the election, the name "Obama" signified hope for millions, not just in America but across the world. As the hope turned to disappointment, the financial crisis deepened and the Arab Spring renewed a call for a "humanity" that could transcend the differences of nations…

As a fifth-grade mathematics teacher, the author tries to create authentic problem-solving activities that connect to the world in which his students live. He discovered a natural connection to his students' real world at a computer camp. A friend introduced him to Alice, a computer application developed at Carnegie Mellon, under the leadership of…

Maps such as concept maps and knowledge maps are often used as learning materials. These maps have nodes and links, nodes as key concepts and links as relationships between key concepts. From a map, the user can recognize the important concepts and the relationships between them. To build concept or knowledge maps, domain experts are needed.…

This study investigates whether a curriculum supplement organized as a sequence of teacher-led literacy activities using digital content from public educational television programs can improve early literacy outcomes of low-income preschoolers. The study sample was 436 children in 80 preschool classrooms in California and New York. Preschool…

Software has an important role in supporting scientific work. This dissertation studies teams that build scientific software, focusing on the way that they determine what the software should do. These requirements engineering processes are investigated through three case studies of climate science software projects. The Earth System Modeling…

Communication underwater is challenging because of the inherent characteristics of the media. First, common radio frequency (RF) signals utilized in wireless communications cannot be used under water. RF signals are attenuated in such as way that RF communication underwater is restricted to very few meters. As a result, acoustic-based…

The purpose of the course presented here is to introduce freshmen to embedded systems using LEGO Mindstorms, under an ANSI-C programming environment. The students build their own LEGO robots, make programs for them using ANSI-C, and operate them. By creating these LEGO robots, the students become more motivated, learning the basic concepts of…

jGRASP has three integrated approaches for interacting with its dynamic viewers for data structures: debugger, workbench, and text-based interactions that allow individual Java statements and expressions to be executed/evaluated. These approaches can be used together to provide a complementary set of interactions with the dynamic viewers. Data…

Almost all collegiate programs in Computer Science offer an introductory course in programming primarily devoted to communicating the foundational principles of software design and development. The ACM designates this introduction to computer programming course for first-year students as CS1, during which methodologies for solving problems within…

Various systems development life cycles and business development models have been popularized by information systems researchers and practitioners over a number of decades. In the case of systems development life cycles, these have been targeted at software development projects within an organization, typically involving analysis, design,…

The Computer Science department at SHSU is currently employing student mentors to assist with recruitment and retention. The primary purpose of these students is to help frustrated new majors in the beginning programming course realize that they are not alone in their struggles and to assist the students over hurdles in their learning and skill…

Dynamic/interactive graphing applets can be used to supplement standard computer algebra systems such as Maple, Mathematica, Derive, or TI calculators, in courses such as Calculus, Differential Equations, and Dynamical Systems. The addition of this type of software can lead to discovery learning, with students developing their own conjectures, and…

Confidence is an important issue for biology students in handling computational concepts. This paper describes a practical in which honours-level bioscience students simulate complex animal behaviour using StarLogo TNG, a freely-available graphical programming environment. The practical consists of two sessions, the first of which guides students…
