ABSTRAK

 

Kajian berkaitan dengan salah konsep pelajar dalam kursus fizik kuantum  jarang dilakukan, kerana tidak ramai pelajar yang terlibat dalan kursus berkenaan. Kajian ini dijalankan bagi membantu mengenal pasti salah konsep pelajar pada tahap awal. Kajian ini bertujuan untuk membina ujian diagnostik yang boleh mendiagnosis salah konsep pelajar sains dan menggunakan dapatan kajian bagi membaiki kaedah Pengajaran dan Pembelajaran kursus fizik kuantum. Ujian Diagnostik Fizik kuantum (UDFK) aneka pilihan yang merangkumi konsep cahaya, model atom, sifat keduaan gelombang-zarah, fungsi gelombang dan graf tenaga keupayaan kuantum, dilakukan kepada 200 pelajar universiti. Kajian menunjukkan bahawa ramai pelajar menggunakan konsep klasik untuk menjelaskan fenomena kuantum. Sebagai contoh pelajar menjelaskan bahawa cahaya adalah gelombang, elektron adalah zarah, dan struktur atom selari dengan sistem suria. Bagi mengatasi masalah ini, dicadangkan agar pensyarah mengambil masa lebih untuk menjelaskan takrifan asas dan kaedah penggunaan analogi dalam pengajaran fizik kuantum.

 

Kata kunci: Cahaya; keduaan gelombang-zarah; model atom; ujian diagnostik; salah konsep

 

ABSTRACT

 

A study on students’ misconceptions on quantum physics is rarely being done, because the target audience is quite small. It is important to understand quantum physics concepts correctly especially for science students. This study was under taken to help students identify their misconceptions at the early stage. The aim of this study is to develop a diagnostic test which can access the students’ misconceptions, and use the findings for the benefits of quantum physics courses. A multiple-choice Quantum Physics Diagnostic Test (QPDT), that involves concepts of light, atomic model, particle-wave dualism, wave function, and potential energy, was administered to 200 university students. The results shows that many students use the classical concepts to describe the quantum phenomenon. For example students describe light only as a wave, an electron only as a particle, and that the atomic structure is parallel to the solar system. To overcome these problems, it is suggested that lecturers spend more time in explaining the basic definitions and using analogies in quantum physics teaching. 

 

Keywords: Atomic model; diagnostic test; light; misconception; particle-wave dualism .
