Polarization of light experimental kit: new design

Polarization is an important property of light that has numerous applications in science and technology. It refers to the orientation of the electric field vector of a light wave as it propagates through space. Polarization is one of the topics that have been taught in the Foundation Physics course. Time constraints and a lack of appropriate laboratory apparatus are the two main reasons why this topic is only being taught theoretically, making it difficult for students to grasp the concept. Due to these constraints, a group of physics lecturers at the Centre of Foundation Studies UiTM Dengkil introduced and developed a simple experimental kit called the “Polarization of Light Experimental Kit” as an initiative to help students’ understanding by visualising the polarization process. This kit is portable, mobile, and easy to handle. Thus, it will attract students' interest and serve as an interesting hands-on activity for them. A preliminary questionnaire survey was distributed to Foundation Science and Engineering students at UiTM Dengkil back in 2017 to assess their understanding on the polarization concept before and after using previous design of this experimental kit in their learning process. From the analysis, about 58% from 120 students agreed that this experimental kit was able to enhance their understanding on polarization of light concept and their interest in learning Physics. The design of this kit is being improvised to make it more practical and attractive to be marketable. Recently, a new survey has been distributed by introducing our new design of the Polarization of Light Experimental kit to a sample of 126 foundation students at Centre of Foundation Studies to assess their understanding on the polarization concept before classroom session, during classroom session and after using the new design experimental kit in classroom learning process. From the analysis, the percentage of the students that agreed the new design experimental kit gave them a better impact on enhancing their understanding and interest on polarization of light concept has increased to 70%. This experimental kit has a high potential to be commercialized as a useful teaching aid for educators and students who want to gain a deeper understanding of the polarization of light concept and its applications.
