Abstract :
This research aims to:(1) develop a practical guide books with psycomotor
assessment instrument based science process skills for student IX grade junior
high school subject of dynamic electricity, (2) knowing the quality practical
guide books with psycomotor assessment instrument based science process skills
for student IX grade junior high school subject of dynamic electricity, (3)
knowing the students respense to practical guide books and enforceability of
practical guide books with psycomotor assessment instrument based science
process skills for student IX grade junior high school subject of dynamic
electricity.
This research is a R&D using procedural modeling. Procedure
development research refers to research procedures puslitjaknov team involving 5
main steps: (1) analizing the products that will be developed, (2) developing the
initial product, (3) expert validation and revision, (4) small-scale field trials and
product revision, (5) and large field trials and the final product. This research
instrument in the form of sheets validation, assessment sheets, and student
response sheets. Assessment of product quality and student responses using 4
likert scale is made in the form of a checklist. Whereas, enforceabiity sheets
product using descriptive statement.
This result of this research are: (1) produced a practical guide books
dynamic electrical containing 3 trial and produced psychomotor assessment
instruments. This product was developed based on the characteristics of
integrated science process skills approach, (2) quality products developed shows
that the practical guide books based on an expert assesssment of material, phsics
teacher junioe high school first stage, and a physics teacher Junior High School 1
Mlati the second stage is very good, with a mean scoresequentially by 3.46; 3.38;
3.65 and psychomotor assessment instrument is very good, with a mean score
sequentially by 3,40 ;3,64; 3,53. (3) student’s response to practical guide books in
small-scale field trials in order are agreed and strongly agreed, with a mean score
sequentially by 3,21 and 3,31. Enforceability of overall product can be done well.
