sample procedure development tool type judging performance Phase II: development stage Phase III test Reliabiltas and validity
Eureka Education . As done in development process preparation in the previous post, we give now the next level, development and testing instrument.
the development phase
at this stage assesman considering assesman terhadapa learning objectives be developed that are tailored to the competence of the services, receive participants learners . The purpose of the design phase Assesman prepare developed. When creating a performance-based assessment tools on, teachers should have a thorough understanding of the skills in learning to listen to be measured. Teachers need to consider the principles in the assessment / evaluation. So teachers can develop valid assessment tool, the listening skills of students can measure.
Assesaman that is developed based assesman assesman on performance or power. prepared Assesamn based on the performance and in the form of formative formative assesman as a guide for the learning process participant students developed. Assesman then during the learning process and pengelolahan class used
According to Mueller (05: 29-31). General principles in the evaluation include (1) classify clear what a considered priority in the evaluation process, (2) an evaluation process for their relevance to the character / should be measured aspects, (3) assessment / evaluation require comprehensive procedures vary selected (4) the assessment procedures are suitable for use, requires an awareness of the limits of the ability of students and (5) assessment is a way to put an end, not an end in itself. to use these principles is to provide based on the available power as an important guide in the development of the assessment.
phase test validity and reliability
In this phase is to test the validity of assesaman that was compiled previously is. there is on the validity of the tests three stages of the validity test konstark, test content validity testing and external validity test. The validity of the request expert assistance konstark testing menganai opinion kesusaian instrument memebrikan be measured with aspects. After passing the test the validity of experts, the next phase will be followed by a test of content validity with mencobakan assesaman that have been made in the research object.
Validation of experts a validation process logically Assesman-based performance management is done by five people Validator, namely: three lecturers and 2 high school teacher. Draft-products which have been validated to lecturers and assessors are to receive for improvement reviews and feedback in order before the trial to the area from the time. The results of the validation will be easier to make changes to the draft product. Once revised, the product can be re-validated, but only to professional teachers, so that it uses for field trials to get a good result for products.
test reliability carried out in conjunction with the test content validity. This test is done by mencobakan assesman on onjek research. This phase aims at the reliability and internal consistency that exist on a performance-based assessment to determine which was developed. At this stage there is a possibility duam assesaman tested elements on the field assesman assesman eligible and ineligible items. assesaman The next item on the position are not worthy to be revised and dilakuakn perbaiakan then checked again until the number of elements required assesamn enough.
stage trial products
Assesman the use of performance-based learning test will be carried out in high school physics class XI IPA program. Interest and trial is designed Assesman and operationalize the necessary learning materials. The results of this study will be used as inputs or final improvements Assesman. Field trials, in addition to the final product Asseman operationalize also the result of the application of Assesman determine Physics in learning, the feasibility Assesman in learning physics in students .
