PENGEMBANGAN PANDUAN PRAKTIKUM SPEKTROSKOPI PADA MATA KULIAH FISIKA MODERN
Abstrak: This study aims
produces a spectroscopic laboratory manual of modern physics, which is valid
and practical. This is the development research that uses 4D (four-D model)
which is modified into a 3D stage. 4D development model that used includes the
steps are defining (define), stage design (design) and stage of development
(develop) combined with Tessmer formative evaluation phase which includes the
step of self-evaluation, expert review, one-to-one and small group evaluation.
laboratory manual based on criteria developed practical guides consisting of
the title experiments, experimental purposes, the basic theory, tools and
materials, experimental procedure, observation data, data analysis and
conclusions. Spectroscopic laboratory manual with a simple tool modification
has been success developed that divided into four trials that determine the
Rydberg constant of the hydrogen atom, determine the energy transition Helium
atom, and determines the wavelength of the optical spectrum and the
determination of the frequency of the laser beam. Data collected through
interviews, expert validation, observation and questionnaire responses of
students. Results of the validation test of the three aspects of assessment
validator average gain of 4.53 with the category of very valid and the results
of the questionnaire responses of students gained an average percentage of
89.28% with a very practical category. The weakness in this study is the lack
of prior knowledge of students in using Matlab software and the limitations of
the tool so that the pilot phase of respondents using practical tools
alternately on each trial. aboratory manual that have been developed can be
used by the student in the learning activities by using practical methods,
especially in the matter of atomic theories of modern physics course.
