Programming Templates: Professional Programmer Knowledge Needed By the Novice

Students first learning to program in any procedural language face the often difficult task of translating solution processes, which they are familiar with, into a form that is bug‐free from a computer standpoint. One element of the differences between the novice and the expert programmer is that the expert already has a set of mappings that allow him or her to translate common solution patterns. This article examines some of the most basic patterns and suggests that students be taught how to recognize them and translate them into code. It is argued that the patterns and the code requirements are similar across a whole range of imperative languages including C, Pascal, Basic, and Cobol.     

Effects of "On-Line" Test Feedback on the Seriousness of Subsequent Errors

The present study examined the effect of three modes of feedback on the seriousness of error types committed on a post-test. The measure of seriousness of error types, or wrong rules, indicates to what extent the wrong rules deviate from the right rule. An on-line, free-response, six-item pre-test covering addition of signed numbers was administered to 263 eighth graders. Upon completion of the pre-test, the students were randomly assigned to receive one of the following kinds of feedback to responses to a second six-item test: (a) information about whether or not the response was correct, (b) the correct answer, or (c) the correct rule for solving the problem. The effect of the feedback mode on the seriousness of errors committed on a third six-item test, the post-test, was found to be differential and dependent upon the seriousness of errors committed on the pre-test.     

George Washington Carver,A Modern Pioneer

One of the most difficult problems that educators face today is dealing with bullying. This pervasive issue occurs in classrooms, lunch rooms, unsupervised areas, on playgrounds, and through electronic media. Based on the principles of protecting the child and establishing a safe environment for all students, this paper investigates the causes and consequences of bullying, and provides information on essentials needed by schools and teachers for effectively dealing with bullying in schools.     

A Review of: “Seeing Beyond Blindness Shelley Kinash”

This project addresses the challenge of preparing educational leaders for future roles in administration in K–12 schools. Through a project-based learning scenario set in a 3-D virtual world, graduate students in school administration and instructional technology worked together in simulated school teams to develop proposals for integrating technology into a fictitious school. The scenario provided parameters within which each team developed a proposal to a superintendent for the use of iPads, which included developing plans for professional development, collaboration among faculty and staff, infrastructure to support the technology, alignment with curriculum, and budgets. Teams worked independently of classes to develop proposals that were then posted in the virtual world for review by instructors and other students. The simulation offered opportunities to develop shared leadership and skills in collaboration outside the usual comfort zone of graduate school classes. Student perception of the value of participation provided insight into the design of the project, which will inform future such collaborative efforts among faculty. Results of student surveys and written reflections are shared as examples of the types of data collected for this project.     

THE IMPACT OF A ‘CITIZEN AFFAIRS’ WORKSHOP ON ANOMIA,LIFE SATISFACTION AND INTERNAL‐EXTERNAL CONTROL IN A SELECTED GROUP OF OLDER ADULTS

An educational experience designed to increase knowledge of the political process, provide peer interaction, and promote civic involvement did appear to enhance internal locus of control in a selected sample of older adults. No significant changes in anomia or life satisfaction occurred. Implications of the findings for educational programming for older adults are discussed. It is suggested that the SRS model used in the study should be tested further for exploring the impact of educational programs upon internal‐external control.     

New approach to visual servo control using terminal constraints

A large class of visual servo controllers relies on an a priori obtained reference image, captured at the desired position and orientation (i.e., pose) of a camera, to yield control signals to regulate the camera from its current pose to a desired pose. In many applications, accessibility and economics of the operation may prohibit acquisition of such a reference image. This paper introduces a new visual servo control paradigm that enables control of the camera in the absence of reference image using a set of terminal constraints. Specifically, the desired pose is encoded using the angle of obliquity of the optical axis with respect to the object plane and its direction of arrival at the plane. A constrained convex optimization problem is formulated over a conic section defined by the terminal constraints to yield an error system for the control problem. Subsequently, this work introduces continuous terminal sliding mode visual servo controllers to regulate the camera to the desired pose. Lyapunov-based stability analysis guarantees that the origin is a finite-time-stable equilibrium of the system. Numerical simulation results are provided to verify the performance of the proposed visual servo controller.
