    Neuro-Psychology of Learning Differences

    This hybrid online course offers full, up-to-the-minute research findings in the brain functions underlying learning, with emphasis on language-learning. Participants will learn about the history of psychology, brain structure, brain development, and neurological anomalies that produce learning differences.

    The course will discuss how to use different intervention strategies based on a better understanding of how neurological conditions affect learning. Specifically, participants will learn how to respond to behaviors and create more effective learning environments both in a one-to-one teaching environment as well as in the classroom.

    Participants will also learn how to read and analyze neuro-psychological testing to design the most effective learning interventions. This class is ideal for all teachers, academic therapists, tutors and parents who wish to better understand the neurological strengths and weaknesses of their learners.

    Dates: September 18- December 11, 2025

    Cost: $975

    Multisensory Math 1 Online

    Instructor: Marilyn Zecher

    Based on the Orton-Gillingham philosophy of teaching, Marilyn Zecher's Multisensory Mathematics I applies the research-based Concrete-Representation-Abstract (CRA) approach to teaching mathematics as advocated by the National Math Panel and the NCTM. Participants learn to apply this methodology in guiding students from foundation skills and numeracy to place value, operations, fractions and decimals. Participants learn to use manipulatives effectively to reinforce concepts, aid memory and enhance performance for all students. Strategies for helping students learn and retrieve math facts are stressed as well as structured procedures for computational accuracy. This approach is especially effective with students who learn differently, inclusion classes and ESL learners. The approach is effective for initial instruction as well as remedial work at all levels and is compatible with all curricula and programs.

    Program Dates:
    September 26, 2025 - December 29, 2025

    With two 90 minute online sessions  with instructors - evening and weekend options available. Scheduling of online sessions will occur after the start of the class.

    You will receive instructions to login to the course on the first day of the course. 

    You will receive your math manual  by the first day of the class. Please provide a SECURE mailing address for delivery of your math manual.

    Refund Policy

    Courses: 50% if withdrawal is at least ten working days before the start of class. No refunds are available less than 10 days prior to the start of class. If a course is sold out, ASDEC will not refund payment at any time.  For more payment details please go to: http://www.asdec.org/ASDEC_payment

    MSM 2 Online 

    Marilyn Zecher presents the follow-up course to Multisensory Math 1. Based on the Orton-Gillingham philosophy of teaching, Multisensory Mathematics II applies the research-based Concrete-Representation-Abstract (CRA) approach to teaching mathematics as advocated by the National Math Panel and the National Council of Teachers of Math (NCTM). Participants learn to apply this methodology in guiding students from foundation skills such as multiplication, division and fractions to operations in upper levels of math including Pre-Algebra, Algebra I, Algebra II and Geometry. This approach is especially effective with students who learn differently, inclusion classes and ELL learners. The approach is effective for initial instruction as well as remedial work at all levels and is compatible with all curricula and programs.


    Online meetings: Dates to be determined with instructor after the course opens.

    Successful completion of Multisensory Math 1 is required prior to enrolling in Math 2.
