A failure to obtain magnetic discrimination in the pigeon

Six pigeons were trained on a multiple-concurrent schedule. During both multiple-schedule components, two response keys were available. In Component 1, responses to the left key were reinforced on a variable-interval 45-sec schedule, whereas responses to the right key were not reinforced. In Component 2, these contingencies were reversed. Following each reinforcer, the component next presented was chosen randomly with equal probability. The two components were differentially signaled by presentation of various stimuli during Component 1. Over the course of the experiment, these stimuli were various intensities of light, a noise, and various fluctuating and static magnetic fields. While subjects showed good discrimination of the light and noise stimuli, no stimulus control using the magnetic fields was obtained.     

The double-edged sword: Critical reflections on traditional and modern technology in outdoor education

The outdoor education experience continues to be influenced by a proliferation of modern technological innovations, most of which have been accepted and even embraced by educators with little inquiry. Seldom do instructors of outdoor programmes consider the impact that modern techniques and equipment can have upon students' learning. This paper argues that in an unexamined adoption of this technology, some of the potential positive impacts for participants can be compromised, including a direct and meaningful connection to the natural world. As such, modern technology has become a possible mediating influence for participants in outdoor education programmes. The paper examines some of the pedagogical issues of modern technology as a mediator of experience as well as several elements of educating in the outdoors with traditional technology. Woven into the discussion is the question of whether modern technology encourages more people to become involved in outdoor activities or merely works toward the separation of humans from the rest of nature.     

Causes and consequences of student evaluation of instruction

Student evaluation of course quality was examined as an intervening variable in a path model with seven input variables and the following two output variables: (1) whether students would recommend the course to others, and (2) students' plans to take more courses in the discipline. Student evaluation of the lecturer was the most powerful input variable for the intervening variable course rating. Class format, defined as lecture or lecture with small groups, did not affect course ratingper se but did relate to students' attitudes toward taking more courses in the discipline. Lecturer and textbook evaluation had significant independent effects on whether the student would recommend the course to others. The major implication for university departments is that quality of instruction in introductory courses has impact on future enrollment plans.     

Complexity Science and Education: Reconceptualizing the Teacher’s Role in Learning

This writing is structured around the question, "What is teaching?" Drawing on complexity science, we first seek to demonstrate the tremendously conflicted character of contemporary discussions of teaching. Then we offer two examples of teaching that we use to illustrate the assertion that what teaching is can never be reduced to or understood in terms of what the teacher does or intends. Rather, teaching must be understood in terms of its complex contributions to new, as-yet-unimaginable collective possibilities.

Neuromuscular,biomechanical, and energetic adjustments following repeated bouts of downhill running

Purpose:This study used downhill running as a model to investigate the repeated bout effect(RBE) on neuromuscular performance,running biomechanics,and metabolic cost of running.Methods:Ten healthy recreational male runners performed two 30-min bouts of downhill running(DR1 and DR2) at a-20% slope and 2.8 m/s3 weeks apart.Neuromuscular fatigue,level running biomechanics during slow and fast running,and running economy parameters were recorded immediately before and after the downhill bouts,and at...     

Basic Irony: Examining the Foundations of School Mathematics With Preservice Teachers

This article reports on an inquiry into what tends to be taken for granted with regard to the teaching and learning of mathematics. The inquiry, undertaken in the context of a course on methods for mathematics teaching, was developed around an examination of the mathematical notions that infuse conventional theories of cognition and that permeate the structures and practices of school mathematics. In particular, concepts drawn from or aligned with Euclidean geometry were examined. Specifically, alternatives drawn from fractal geometry were explored. The importance of interrogating the often-transparent figurative underpinnings of our thinking about thinking is highlighted.
