• Learning can and often does take place without the benefit of teaching – and sometimes even in spite of it – but there is no such thing as effective teaching in the absence of learning. Teaching without learning is just talking. (p. 3) • Classroom Assessment is an approach designed to help teachers find out what students are learning in the classroom and(More)
1. What is "Classroom Assessment"? "Classroom Assessment" is a formative rather than a summative approach to assessment. Its purpose is to improve the quality of student learning, not to provide evidence for evaluating or grading students. It provides faculty with feedback about their effectiveness as teachers, and it gives students a measure of their(More)
The instruction that we provide, the intellectual climate that we create, and the policy decisions that we make should all start with the question, "But will it improve students' learning?" Basic to any answer is the state of our knowledge about learning. A spate of recent research has resulted in comprehensive and lengthy reviews of surveys of research on(More)
The descending contralateral movement detector (DCMD) is a high-performance interneuron in locusts with an axon capable of transmitting action potentials (AP) at more than 500 Hz. We investigated biophysical mechanisms for fidelity of high-frequency transmission in this axon. We measured conduction velocities (CVs) at room temperature during exposure to 10(More)
We compared how different metabolic stressors, anoxic coma and food deprivation, affected signaling in neural tissue. We used the locust's Descending Contralateral Movement Detector (DCMD) interneuron because its large axon, high firing frequencies, and rapid conduction velocity make it energetically expensive. We exposed locusts to a 30min anoxic coma or(More)

Many of us have some skepticism about the enterprise of assessment, which is fairly new as a systematic, campus-wide effort at Knox. We have been asked by the Higher Learning Commission to join the mainstream of higher education by turning our ongoing attention and efforts to assessment at both the program and the college levels. On behalf of your fellow(More)
Mechanisms that could mitigate the effects of hypoxia on neuronal signaling are incompletely understood. We show that axonal performance of a locust visual interneuron varied depending on oxygen availability. To induce hypoxia, tracheae supplying the thoracic nervous system were surgically lesioned and action potentials in the axon of the descending(More)
