Ability grouping is a common practice in today's classrooms, which involves using intelligence tests to place individuals into certain academic groups with others who have the same abilities. Two types of ability grouping include between-class grouping and within-class grouping, which provides both benefits and obstacles in a classroom setting. When a school or teacher groups students "according to their ability or achievement," the school practices cross-class ability. grouping (Santrock 125). In many cases, ability grouping across classes is used in a high school setting as a way to group students with similar goals and abilities. At first glance, ability grouping across classes appears to benefit all students because it allows teachers to better teach students in a more targeted way. However, researchers have determined that this form of grouping harms those in a lower-ability group (125). Recently, when I was helping out at a lower-achieving high school, this form of grouping was clearly evident. Students were clearly divided into classes based on their abilities. Each class reviewed the same material, but each teacher taught the material differently to meet the needs of that group of students. The history classroom, considered an advanced placement class, ran much more smoothly and students had a good understanding of the topic and appropriate behavior. However, “average” history lessons were a little more chaotic and students had little to no interest in the topic. This example I witnessed showed how skill grouping across classes benefits those on a “higher path” and leaves those in lower classes behind. Students in “low track” classes commonly belong to a middle class… and. Much of school, especially in the early grades, is helping children understand how to express emotions appropriately. This strategy helps all students, but especially emotional students, because they need to understand how to convey to the teacher and other classmates what they feel without the explosion of any specific emotion. As a teacher it is important to adopt many of the strategies to help teach. children based on different temperaments. When teaching different temperaments, it is important to show attention to all students individually, which is of great benefit to students of all temperaments. Given the many individual traits of children, a teacher has the diverse task of educating each individual child in the best way. Works Cited Santrock, John. Educational psychology. 5th ed.
