INTRODUCTION
 Evaluation is a process of making judgements to be used as a
  basis for planning.
 It  consists of establishing    goals, collecting evidence
  concerning growth towards goals, making judgements about
  the evidence and revising procedures and goals in the light of
   judgements.
 Itis for improving the product, the process and even the
  goals in themselves.
 Evaluationis the process of determining to what extend the
  educational objectives are being realized - Ralph Tyler

TYPES OF EVALUATION
 FORMATIVE EVALUATION
            - (process evaluation)
 SUMMATIVE EVALUATION
             -(product evaluation)
FORMATIVE EVALUATION
 Itrefers to evaluation taking place during the program or
  learning activity.
 It is conducted while the event to be evaluated is
  occurring and focuses on identifying the progress towards
  purposes, objectives, or outcomes to improve the
  activities, course, curriculum, program or teaching and
  student.
 Formative  evaluation is also useful in analyzing learning
  materials, student learning and achievements, and
  teacher effectiveness.
Types
 needs assessment
 Evaluability assessment
 structured conceptualization
 Implementation evaluation
 Process evaluation
Advantages
 Emphasize the parts instead the entity
 The events are recent thus of marking accuracy and
 preventing distortion by time
 The   results can be used to improve student
  performance, program of instruction, or learning
  outcome before the program or course has concluded
Disadvantages
 Making judgment before the activity is completed and
  not being able to see results before judgments are
  made intrusive.
 Interrupt the flow of outcomes.
 Chance for a false sense of security when formative
  evaluation is positive and the final results are not
  positive as predicted earlier.
SUMMATIVE EVALUATION
 Summative evaluations,   examine the effects or outcomes
  of some object.
 A summative evaluation (sometimes referred to as external)
  is a method of judging the worth of a program at the end of
  the program activities (summation). The focus is on the
  outcome.
 Summative evaluation refers to assigning a grade for
  students achievement at the end of the course or
  instructional program.
Types
   outcome evaluations
   impact evaluation
   cost-effectiveness and cost-benefit analysis
   secondary analysis
   meta-analysis
Advantages
All work has been completed and the findings
 of evaluation is that nothing can be done to
 alter the results.
