Science process
skills are overall scientific skills that can be used to find a concept or
theory. One method to train the learning process of students is through the
guided discovery learning method. Guided discovery-based learning can be
applied using student worksheet which is oriented towards scientific discovery
activities. This study was designed to produce valid and practical student
worksheet based on guided discovery to train integrated science process skills
in Enzyme Sub materials. The study was conducted in October 2019 to March 2020
in the Biology Department, Faculty of Mathematics and Natural Science, State
University of Surabaya. The type of this research is development research using
the ADDIE development model (Analysis, Design, Development, Implementation, and
Evaluation). At the time of analysis, it is done by analyzing the curriculum,
students, concepts, and assignments. The design stage is completed with
designing the student worksheet which is adapted to the syntax of the guided
discovery. Further development (including) development, review, and revision,
as well as validation of the student worksheet. Later the evaluation
(Evaluation) of the validation results will be analyzed and evaluated. Validity
is the feasibility of student worksheet which is determined by three validators
given by lecturers of materials, education teachers, and high school biology
teachers. The validity of the student worksheet was reviewed in terms of
content validity, presentation, language, the suitability of the guided
discovery method, and integrated science process skills. The method used in
this study is the questionnaire method, validation method, and readability
test. The instruments used were validation sheets and readability test sheets.
Data analysis in the form of descriptive qualitative. The results showed that
the guided discovery student worksheet was declared empirically feasible for
use in XII high school students, and was declared valid with an average score of
validation results of 3.81 with a very valid category and can be
used in the learning process.
