Principal Quantum Number Definition

Principal Quantum Number Definition The principal quantum number is the  quantum number denoted by n and which indirectly describes the size of the electron orbital.  It is always assigned an integer value (e.g., n 1, 2, 3...), but its value may never be 0.  An orbital for which n 2 is larger, for example, than an orbital for which n 1. Energy must be absorbed in order for an electron to be excited from an orbital near the nucleus (n 1) to get to an orbital further from the nucleus (n 2). The principal quantum number is cited first in the set of four quantum numbers associated with an electron. The principal quantum number  has the greatest effect on the energy of the electron. It was first designed to distinguish between different energy levels in the Bohr model of the atom  but remains applicable to the modern atomic orbital theory. Source Andrew, A. V. (2006). 2.

Building a Complete School Retention Form

Building a Complete School Retention Form Student retention is always highly debated. There are clear-cut pros and cons that teachers and parents must take into consideration when making such an important decision. Teachers and parents should work together to come up with a consensus as to whether or not retention is the right decision for a particular student. Retention will not work for every student.   You must have strong parental support and an individualized academic plan that promotes an alternative to how that student is taught as compared to previous years. Each retention decision should be made on an individual basis. No two students are alike, thus retention must be examined taking into account the strengths and weaknesses of each individual student.   Teachers and parents must examine a wide array of factors before deciding whether or not retention is the right decision.   Once a retention decision has been made, it is important to explore how the students individual needs are going to be met at a deeper level than before. If the decision is made to retain, it is important that you adhere to all guidelines laid out in the districts retention policy. If you have a retention policy, it is equally important that you have a retention form that gives a brief description of the reasons the teacher believes the student should be retained. The form should also provide a place for to sign and then either agree or disagree with the teachers placement decision. The retention form should summarize placement concerns. However, teachers are strongly encouraged to add additional documentation to support their decision including work samples, test scores, teacher notes, etc. Sample Retention Form The primary goal of Any Where Public Schools is to educate and prepare our students for a brighter tomorrow. We know that each child develops physically, mentally, emotionally, and socially at an individual rate. Additionally, not all children will complete twelve grades levels of work according to the same pace and at the same time. Grade level placement will be based on the child’s maturity (emotional, social, mental and physical), chronological age, school attendance, effort, and marks achieved. Standardized testing results can be used as one means of the judging process. The grade marks earned, direct observations made by the teacher, and academic progress made by the student throughout the year shall reflect the probable assignment for the coming year.
