Covid-19 Pandemic had a dramatic effect on practicing everyday
routines including education. Due to the fatality the virus, schools are forced
to close and in many cases remote teaching has become a necessity. Although,
online teaching provides some solutions to the educational problems in
difficult times such as pandemic, natural disasters or people who lives in
remote areas, it does not develop still for the full capacity to meet the all
challenges of distance education. Therefore, there still a way to go for
effective online education. One of the most important challenges of online
education is the aces to the hands on activities which we have in face to face
education. In order to overcome this problem, we aimed in this study to
investigate the possibility of using developing hands on supplementary
materials and implement in during individualized education settings during
Covid-19 pandemic to teach symbolic language of the chemistry in high school.
It is hard to keep students’ motivation and interest high towards chemistry in
distance education. We thought providing supplementary hands on materials to
students may enhance their motivation and interest towards chemistry and this
may result more effective learning in individualized learning environment for
the high school students. Within this framework, this study particularly aimed
at examining the effect of video lessons supplemented with 3D hands on
materials on strong intramolecular interactions to ninth grade students in an individualized
instruction trial during Covid-19 lockdowns.
The design-based research approach has been implemented in
development of the 3D instructional supplementary materials while the
effectiveness study was designed as an intervention mixed design. Design-based
research combines teaching methods and techniques with designed teaching
materials and activities and produces products that have meet the teaching
needs. In addition, it is a method that enables the emergence of effective
teaching materials by making necessary evaluations in the application and
analysis of the designs that are related to learning theories and will be
developed in the research. This method is used in the design phase and will
help to create practical designs that can be used to describe the symbolic
language of chemistry by eliminating the deficiencies of the materials to be
designed. In the implementation phase, mixed research design with intervention
was used. This design is a research that provides a solution to the identified
problem by adding qualitative data to the research process by implementing an
intervention (experiment/treatment) program. During investigating the effectiveness
of the teaching qualitative data were also used to better understand the
effectiveness of the materials and their effect on success, as well as
quantitative data.
The study group of the research consists of five students and four
parents. After the materials designed and developed, produced with 3D printers,
and educational videos supporting them are prepared, a pre-test is given to
five students in the treatment group. The application has started with the
delivery of materials and videos to the students. The students have tried to
learn the subject on their own, that is, individually, by watching three videos
and using 18 supplementary 3Dmaterials. The process is completed with the application
of the post-test at the end of the application and the interviews with the
students and their parents took place. Pre and posttest data were subjected to
the gain score analysis and the interview data were content analyzed. The results
showed that video lessons supplemented with 3D materials are enhanced students’
understanding and long-term retention of the subject learned as well as
improved visual and spatial abilities. 3D supplementary materials embody
abstract concepts in chemistry. The results will be further discussed in the
presentation.
