Every child has a biological father, but if the parents are not married, the child has no legal father, and the biological father has no rights or responsibilities to the child. In order for the biological father to be the legal father, the parents must establish paternity for the child.
Dr. Rick DuFour defines a professional learning community (PLC) as âa group of people working interdependently toward the same goal.â1 Interdependence is an essential element because it:
Problems that can be localized to a specific I/O module or even a specific input or output device are usually external, while internal problems normally result in large groups of failures, globally erratic behavior, or even total failure of the PLC system. Let's look first at the possible causes for internal problems. The first thing to check is the integrity of the PLC's power and ground. Visually inspect the power and ground wiring, looking for loose, corroded, or otherwise questionable connections. The integrity of the ground can be electrically checked by measuring the voltage between the PLC ground terminal and a known ground.
