Action Research in Education
'This structured and accessible book, with excellent case studies, will give confidence to anyone embarking on an action research project'-Professor Ken Jones, Dean of Humanities, Swansea Metropolitan University 'Masterly in its lucidity, this text contextualises Action Research in the fiedl of Education Practice; and is therefore a valuable resource in both professional learning and improved professional practice'-Effie Maclellan, Research Professor in Education, University of Strathclyde, Glasgow 'An engaging, clearly written, and helpfully structured articulation of how AR can be implemented and practised in order to make a difference within educational contexts'-Dr Stephen Parker, University of Worcester 'Will assist practitioner researchers to develop a profound and critical understanding of this approach'-Professor Marion Jones, Liverpool John Moores University This hands-on and user-friendly book uses illustrative case studies to demonstrate and explore the potential for change in real social situations.This book seeks to assert the academic integrity of action research and to de-mystify the process. Each chapter includes: - a 'how to' section based on concrete examples and dilemmas - commentary that relates examples to the broader field - a discussion of the underlying theoretical approach - discussion and exploration of quality issues - discussion of ethical and pragmatic decision-making The mix of theoretical grounding and focus on real issues will be of benefit to Master's level or advanced undergraduate students on Education and Research Methods courses or those undertaking Action Research as part of professional development activities. Mary McAteer is Director of the Mathematics Specialist Teacher (MaST) programme at Edge Hill University Research Methods in Education series: Each book in this series maps the territory of a key research approach or topic in order to help readers progress from beginner to advanced researcher. Each book aims to provide a definitive, market-leading overview and to present a blend of theory and practice with a critical edge.All titles in the series are written for Master's-level students anywhere and are intended to be useful to the many diverse constituencies interested in research on education and related areas. Other books in the series: - Using Case Study in Education Research -Qualitative Research in Education, Atkins and Wallace - Ethnography in Education, Mills and Morton

How does an action potential occur?
An action potential occurs when a neuron receives a stimulus that causes a change in its membrane potential. This change in membrane potential triggers the opening of voltage-gated ion channels, allowing an influx of sodium ions into the cell. This influx of sodium ions depolarizes the cell, causing the membrane potential to become more positive. Once the membrane potential reaches a certain threshold, it triggers the opening of more voltage-gated ion channels, leading to a rapid depolarization of the cell and the generation of an action potential. After the action potential, the cell repolarizes and returns to its resting state.
-
What is the difference between action potential and resting potential?
Resting potential is the electrical charge across the cell membrane of a neuron when it is not sending signals. It is typically around -70 millivolts. Action potential, on the other hand, is a brief electrical impulse that travels down the axon of a neuron when it is stimulated. It is a rapid change in the membrane potential from negative to positive, and it is the basis for neural communication. In summary, resting potential is the baseline electrical charge of a neuron, while action potential is the transient change in electrical charge that allows for communication between neurons.
-
Why is a resting potential necessary for an action potential?
A resting potential is necessary for an action potential because it provides the baseline electrical charge that allows the neuron to respond to stimuli. The resting potential is a stable negative charge inside the neuron, which is maintained by the sodium-potassium pump and potassium leak channels. This stable charge allows the neuron to quickly and efficiently respond to incoming signals by generating an action potential when the threshold is reached. Without a resting potential, the neuron would not be able to effectively transmit and process information.

What is the difference between resting potential and action potential?
Resting potential is the electrical charge across the cell membrane of a neuron when it is not actively sending a signal. It is typically around -70 millivolts and is maintained by the sodium-potassium pump. Action potential, on the other hand, is a brief reversal of the electrical charge that occurs when a neuron is sending a signal. It is a rapid depolarization and repolarization of the cell membrane, resulting in the transmission of an electrical impulse along the neuron.

What is the action potential for dummies?
The action potential is a brief electrical impulse that travels down the axon of a neuron. It is the fundamental unit of communication in the nervous system, allowing neurons to transmit information to other neurons, muscles, and glands. The action potential is generated when the neuron receives a strong enough signal from its surroundings, causing a rapid change in the neuron's membrane potential. This change in membrane potential triggers the opening of voltage-gated ion channels, leading to the propagation of the action potential down the length of the neuron.

What is an action potential in neurobiology?
An action potential is a brief electrical signal that travels along the membrane of a neuron. It is generated when the neuron receives a strong enough stimulus, causing a rapid change in the neuron's membrane potential. This change in membrane potential triggers the opening of voltage-gated ion channels, allowing an influx of positively charged ions into the neuron, which then propagates the electrical signal down the length of the neuron. Action potentials are essential for communication between neurons and are the basis for the transmission of information in the nervous system.

Why is receptor potential referred to in rods and not action potential?
Receptor potential is referred to in rods because rods are specialized sensory cells in the retina that are responsible for detecting light. When light strikes the rods, it triggers a change in their membrane potential, known as the receptor potential. This change in membrane potential is a graded response that reflects the intensity of the light stimulus, and it is not strong enough to trigger an action potential. Action potentials are typically generated in neurons and are a more dramatic change in membrane potential that allows for long-distance signaling.

What is the difference between resting potential and action potential in neurobiology?
Resting potential is the electrical charge across the cell membrane of a neuron when it is not being stimulated. It is typically around -70 millivolts and is maintained by the unequal distribution of ions inside and outside the cell. Action potential, on the other hand, is a brief electrical impulse that travels down the axon of a neuron when it is stimulated. This occurs when the membrane potential reaches a certain threshold, causing a rapid depolarization and repolarization of the cell membrane. In summary, resting potential is the baseline electrical state of a neuron, while action potential is the transient electrical signal that allows neurons to communicate with each other.
