In the 21st
century, the competence of instructional technological design is important for
pre-service physics teachers. This case study described the pre-service physics
teachers' design of optical spreadsheet simulation and evaluated teaching and
learning the task in the classroom. In this
case, participants were three pre-service teachers (two male and one female)
chosen from 30 Physics students of Yogyakarta State University. They have been
attending optics course for 14 weeks in 6th semester of the academic year 2016.
They aged 23 to 26 years old. All of them have followed basic computer program
like Word, PowerPoint, and Excel.
A bonded
system explored basic knowledge and integration ability of the pre-service
teacher. In addition, peers assessed the simulated performance of pre-service
teachers by using Spreadsheet-Technological Pedagogical Content Knowledge
(S-TPACK). Pre-service teachers transform the topic into a unique spreadsheet
simulation. One of them designed with high complexity, but the others are not.
However, they demonstrated different the intensity and integrity of teaching
strategies, the depth of optical topics, and interactive spreadsheets. In the
future, the design of instructional technology will need to pay attention to
the basic knowledge of TPACK, problem-solving, and self-efficacy.
This case study has three implications
in design and spreadsheet simulation. The first, the study recommends using
spreadsheets for easy, cheap and flexible purposes in designing physics topics.
Three pre-service teachers have proven that they have designed different
optical topics with different forms and interactive. Second, design activities
require knowledge, skills, and attitudes. (1) Basic knowledge is required as
the main capital in the design that is knowledge of appropriate physics topic,
technological expertise, and pedagogical knowledge. (2)
Creativity design helps in integrating technological skills into
the knowledge of physics topics and pedagogical knowledge at once. Design
creativity requires problem-solving and decision-making skills in brainstorming
conditions. Strong imagination also helps to get a unique design. (3)
Self-efficacy, self-believe, or confidence is required to assure the ability to
achieve an optimal design. Finally, simulation activities can be evaluated
using S-TPACK and peer comments. S-TPACK helps pre-service and instructor to
know the intensity of PK, CK, and TK from the diagram. In addition, S TPACK can
show PCK, TCK, and PTK based on PK, CK, and TK diagram intersections.
