![]() ![]() Because time is limited and fixed, wasted time on one topic will shorten the amount of time available to teach other topics. Below I discuss instances when the CCSS-M may lead to the numerator in Carroll’s model being significantly larger than the denominator-when teachers spend more time teaching a concept or skill than is necessary. Time is a limited resource that teachers deploy in the production of learning. They need more time.Īs applied to Common Core and instruction, one should also be aware of problems that arise from the inefficient distribution of time. When that happens, students don’t have an adequate opportunity to learn. Most applications of Carroll’s model have been interested in what happens when insufficient time is provided for learning-in other words, when the numerator of the ratio is significantly less than the denominator. Berliner notes that although both are typically described in terms of motivation, they can be measured empirically in increments of time. Carroll called this persistence, and Berliner links the construct to student engagement and time on task-topics of keen interest to researchers today. Berliner’s 1990 discussion of time includes an analysis of mediating variables in the numerator of Carroll’s model, including the amount of time students are willing to spend on learning. This is often referred to as “students working at their own pace,” and progress is measured by mastery of content rather than seat time. It is predicated on the idea that optimal learning occurs when time spent on learning-rather than content-is allowed to vary, providing to each student the individual amount of time he or she needs to learn a common curriculum. Benjamin Bloom’s “ mastery learning” was deeply influenced by Carroll. As of July 5, 2015, Google Scholar reported 2,931 citations of Carroll’s article. The model has had a profound influence on educational thought. There are also announcements over the PA system, stray dogs that may wander into the classroom, and other unscheduled encroachments on instructional time. Teachers allot time to instruction only after educational authorities have decided the number of hours in the school day, the number of days in the school year, the number of minutes in class periods in middle and high schools, and the amount of time set aside for lunch, recess, passing periods, various pull-out programs, pep rallies, and the like. Teachers obviously have limited control over the denominator of the ratio (they must take kids as they are) and less than one might think over the numerator. The source of that variation is largely irrelevant to the constraints placed on instructional decisions. Slice it ccss how to#He also spoke directly to a primary challenge of teaching: how to effectively produce learning in classrooms populated by students needing vastly different amounts of time to learn the exact same content. nurture) and the vocabulary that labels students as having more or less intelligence. ![]() ![]() By expressing aptitude as time needed to learn, Carroll refreshingly broke through his era’s debate about the origins of intelligence (nature vs. The denominator, time needed to learn, is synonymous with student aptitude. The numerator, time spent learning, has also been given the term opportunity to learn. Carroll proposed a parsimonious model of learning that expressed the degree of learning (or what today is commonly called achievement) as a function of the ratio of time spent on learning to the time needed to learn. Carroll published a short essay, “A Model of School Learning” in Teachers College Record. I dubbed the three-part examination of instruction “The Good, The Bad, and the Ugly.” Having discussed “the “good” in part one, I now turn to “the bad.” One particular aspect of the Common Core math standards-the treatment of standard algorithms in whole number arithmetic-will lead some teachers to waste instructional time. This is part two of my analysis of instruction and Common Core’s implementation. ![]()
