The Validity of A Leaner Based Worksheets Based Discovery Learning on The Matter of Biology For Grade 8 VII Students Of Junior High School

Abstract

During the learning of the students already use worksheets. The worksheets are used by learners only contains the steps work or experiment. Besides the learning process simply involves an explanation of the teacher and gives only a question or FAQ on learners so that the learners are less able to develop problems contained in the learning material. At the time of an activity on a worksheet learners are less actively involved in the learning process. At the time of an activity on a worksheet learners are less actively involved in the learning process, learners passive and rely solely on his friend to work. For addressing these problems, then developed a worksheet learners Based Discovery learning. The purpose of this research is to develop a worksheet-based Discovery learning learners and to know the criteria validitasnya. This type of research is the development by using model Plomp. Development model Plomp consists of three stages of development, namely: the initial investigation phase, a phase of development and prototyping phase and the phase of assessment.  data-collecting instrument used is the instrument the validity of student worksheets. Learner worksheets based Discovery learning validated by four experts. The results showed that the feasibility aspect of content, presentation and language and graphical aspects of the obtained score of 75.00%, 78.69%, 76.19% 78.57%, and with a valid category. So it can be inferred that a worksheet-based Discovery learning students acquire a valid category so that viable use for the learning process and expected can improve student learning outcomes.
