PLEASANT VALLEY SCHOOL DISTRICT



Brodheadsville, Pennsylvania 18322



PLANNED COURSE ADAPTATIONS/MODIFICATIONS
 



Introduction
 

 The instructional adaptations that follow are provided as suggestions to be implemented with all students, particularly with those in need of special education services including the gifted. This listing is in no way intended to be exhaustive. Rather, it is reflective of some major considerations in the area of curriculum adaptations/modifications.
 
These instructional adaptations will work with any student, but are especially beneficial to those in need of learning support. Some may argue that these modifications are simply good teaching. Indeed, modifications of this type do represent good teaching. These principles of good teaching become instructional modifications whenever: (1) certain students in a particular class require such modifications above and beyond what is typically required by most students in that class and (2) without these modifications, these same students would not succeed.
 
Assessment is an integral part of instruction reflecting student progress as well as achievement. Therefore, also included are suggestions for assessment modifications.
 
 
§   Peer Support
§   Cooperative learning among peers
§   Modeling
§   Development of Information Organizer
§   Development of Graphic Organizer
§   Development of structured study guides
§   Student selection of instructional material (i.e., reading, writing, math)
§   Taped lessons
§   Copy notes (peer or teacher)
§   Student conferencing
§   Combine and vary modes of lesson presentation
§   Adjust language level to match the developmental and intellectual levels of students
§   Let student practice given examples first. Then assign tasks to be completed.
§   Provide opportunity for guided and independent practice in a variety of situations
§   Limit number and length of directions
§   Have students repeat/review directions (i.e., peer to peer, student to teacher)
§   Give feedback that is as immediate, specific, and objective as possible
§   Clarify error responses so that students do not make the same errors over and over again
§   Reinforce progress towards desired outcomes
§   Breakdown complex tasks into smaller, more manageable units
§   Use verbal prompts to elicit desired results
§   Use manual guidance (i.e., hand over hand) to facilitate correct responses
§   Computer assisted instruction
§   Assessment based upon teacher observation of student performance (i.e., daily work, portfolio, artifacts, projects)
Extended test time
§   Test read to student by teacher or peer
§   Oral testing (i.e., student retelling of information)
§   Open book/note test
§   Alternate testing (any demonstration of a student's understanding of concepts)
§   Retesting
§   Reduce the number of responses required on tests
§   Use of curriculum based assessment
§   Vary test format

PREFACE
 

 
 
Users and information seekers should familiarize themselves with the purpose and terminology of this Planned Course
Curriculum Guide (PCCG). We suggest that you first read the following:
 
 
            • PCCG PURPOSE AND INTENT



           • PCCG DEFINITIONS
 
 
  The PCCG specifies the unit lesson outcome, essential content, standards, activities, resources, and evaluation of student performance. This sector provides the means to initiate the learning activities to attain the program goal as identified in the course description and intent.
 
 The standards and outcomes are minimal expectations; further embellishment of the course is discretionary with the instructor depending upon the capability of the students.
 
 This PCCG is designed as an ACTIVE document capable of technological modification as required.
 
 The instructional delivery of this curriculum is quality controlled through the lesson plan development of the teacher.

PURPOSE AND INTENT
 

   
The Planned Course Curriculum Guide (PCCG) is a multi-purpose document:
    
All staff, particularly new teachers, can understand instructional expectations through the WRITTEN curriculum
A continuing district-wide instructional process and scope and sequence of subject matter are enhanced. The WRITTEN curriculum is delivered through the TAUGHT curriculum [instructional content and learning activities] and is evaluated through the TESTED curriculum [expected levels of student achievement - learning outcomes]
Priority student-centered outcomes are identified and attained through suggested learning activities and content designed to help insure a balanced and comprehensive basic curriculum
Essential content and course standards provide an efficient basis for selecting appropriate instructional materials and resources
           
Staff development areas for curriculum improvement are provided
The PCCG conforms with current Pennsylvania Department of Education curriculum regulations and serves the dual feature of providing both an administrative document and an instructional guide
Content and subject format remain flexible and adaptable to modification - an “active” document
Special Pennsylvania Department of Education [PDE] legislation is identified
Parents and students are provided with an overview of the instructional program and each course in particular
