Acellus could change your school

The Movement that is Changing Education

Acellus is changing the face of education as we know it. Schools using Acellus vastly expand the educational opportunities available to each student, leverage teachers’ personalized attention to every learner, and empower teachers to facilitate every student with individualized instruction.

Acellus empowers learners to study at their own pace, adapts core educational experiences to the learner, and personalizes instruction to address students’ individual and unique learning styles. Acellus also ensures that all instructors have access to high-quality educational material, while greatly reducing repetitive, time-consuming tasks that impede their methods and techniques of teaching.

Acellus systematically reviews the science behind the learning process, studies the delivery of curriculum, discovers innovative solutions to teach more effectively, and empowers students to be college ready and career prepared. Acellus has become a significant dynamic in enabling schools to implement blended learning into their curriculum. The Acellus Learning Program is expanding rapidly, currently reaching more than 2.5 million students in all 50 states as well as 47 countries worldwide.

Why Acellus Works - Applying the Scientific Method

Swiss Cheese Problems

Acellus delivers short video lessons taught by some of our nation’s greatest teachers.  After each lesson, students receive practice problems to reinforce their understanding of the concepts.  Acellus uses Deficiency Diagnostics (DD) to assess any areas of weakness in their knowledge and give more help and practice in these areas through customized personal instruction (CPI).  By recognizing deficiencies and personalizing the learning process, Acellus is able to fill in holes in students’ understanding for a strong academic foundation.

In Acellus, we create special problems for the purpose of identifying where a student has a hole in their background knowledge that’s making it hard for them to learn a particular concept. This special kind of a problem in Acellus we call a “Swiss Cheese Problem,” because it helps us find holes in a student’s understanding.

Helping Every Student Succeed

According to the “Success Zone” philosophy developed by Dr. Roger Billings, 100 percent of the students in a class CAN succeed in learning. The challenge is to transform “stuck” students into successful learners.  One of the principle missions of Acellus is to empower the teacher in helping each student find their Success Zone.

  • The “Student Success Zone” is an education strategy that helps students succeed by getting into the right courses, at the right levels, to consistently progress. We call this being in their “Success Zone.” On the Acellus Learning platform, the following aids are provided to teachers:
  • Live monitoring of students as they work in the Acellus environment. Teachers can see exactly what every student is working on at any given moment, down to specific problems and the student’s responses
  • Monitoring of overall student progress within a course and notifications to the teacher when students need intervention
  • Data-backed suggestions of intervention options
  • Streamlined implementation of interventions selected by the teacher with a simple click of a button

Student Success Zone

Sometimes the intervention needed is just extra encouragement or help with a specific problem, which is performed by the teacher. However, in cases where students need more extensive intervention, such as having the difficulty of a course increased or reduced, or moving a student to a more basic or more advanced course, the Success Zone provides a “select and click” way to implement.
