Abstract

The purpose of this study is to analyze the probability and uncertainty of electron linear momentum in with the Heisenberg uncertainty approach. Measurement of the position and momentum of atomic electrons is probabilistic. The probability and uncertainty of electron linear momentum are analysed analytically, and simulations of hydrogenic atoms' normalized radial wave function are performed.  they can be viewed as hydrogenic atoms with only one electron orbital. The probability and uncertainty of electron linear momentum in decrease with increasing values of the principal quantum number n ≤ 3. While the uncertainty of the electron position is increasing.  The results of this study are in accordance with the characteristics of position and linear momentum that are not commutable. The increase in the value of the main quantum number means that the electron's position against this is getting farther, and the speed in the orbital is getting smaller.

Abstract

This study aimed to identify the conceptual understanding and types of misconceptions demonstrated by senior high school students in dynamic electricity using a web-based Four-Tier Diagnostic Test. The study employed a quantitative descriptive design involving 91 twelfth-grade students from a public senior high school in Jember, Indonesia, selected through purposive sampling. The validated instrument consisted of 30 items, each comprising a conceptual answer, answer-confidence rating, supporting reason, and reason-confidence rating. Expert validation yielded an overall feasibility score of 96%, indicating that the instrument was feasible for use. Students’ responses were classified as understanding the concept, not understanding the concept, misconception, or error based on the combinations of answers, reasons, and confidence levels. Across the student-item responses, 18% were classified as understanding the concept, 27% as not understanding the concept, 42% as misconceptions, and 13% as errors. Among the misconception-classified responses, theoretical misconceptions accounted for the largest proportion at 19.3%, followed by correlational misconceptions at 17.8%, calculation misconceptions at 16.9%, basic misconceptions at 16.4%, language-interpretation misconceptions at 15.3%, and systematic misconceptions at 14.3%. These findings show that students experienced substantial difficulties in understanding fundamental principles and connecting related concepts in dynamic electricity. The instrument can provide teachers with diagnostic information for designing targeted instructional and remedial activities.
