Cluster grouping is an educational process in which four to six gifted and talented (GT) or high-achieving students or both are assigned to an otherwise heterogeneous classroom within their grade to be instructed by a teacher who has had specialized training in differentiating for gifted learners.

There are eight basic learning centers in an early childhood/elementary classroom, according to the Stephen F. Austin State University Charter School program, each structured to expand the students’ experiences in a variety of meaningful and effective ways. Each center is constructed to encompass numerous objectives, including state and ...
Regular classroom teachers should not schedule tests, special events, or new topics during the pull-out. [14] Pull-out students can prove their mastery of the regular classroom material by answering a small subset of the problems containing the most challenging material. [15] A single, larger block of time is preferable to two or more smaller ...
are arranged around the chiral center carbon atom. With the hydrogen atom away from the viewer, if the arrangement of the CO→R→N groups around the carbon atom as center is counter-clockwise, then it is the L form. [14] If the arrangement is clockwise, it is the D form. As usual, if the molecule itself is oriented differently, for example ...
The 21st Century Community Learning Centers (21st CCLC) initiative is the only federal funding source dedicated exclusively to afterschool programs. The No Child Left Behind Act (NCLB) reauthorized 21st CCLC in 2002, transferring the administration of the grants from the U.S. Department of Education to the state education agencies .
A chiral molecule is a type of molecule that has a non-superposable mirror image. The feature that is most often the cause of chirality in molecules is the presence of an asymmetric carbon atom. [16] [17] The term "chiral" in general is used to describe the object that is non-superposable on its mirror image. [18]
Chiral molecules will usually have a stereogenic element from which chirality arises. The most common type of stereogenic element is a stereogenic center, or stereocenter. In the case of organic compounds, stereocenters most frequently take the form of a carbon atom with four distinct (different) groups attached to it in a tetrahedral geometry.
The students were to engage in the math or reading activities as teams. Paying attention, engaging in the lessons or activity, was the "good behavior". If students engaged in actions that interfered with the lesson (e.g., getting out their seat, interrupting), that was a penalty point against the team—much like playing a sport.
