While Hong Kong students excel at international tests in mathematics, they do not display corresponding attitudes toward mathematics learning. This study examined 10 Hong Kong Secondary 6 students' perceptions of learning mathematics (experiential curriculum) and their perceived factors that limited the development of students' positive attitudes toward mathematics learning in the New Senior Secondary mathematics curriculum by content analysis of their responses in the interviews. Although the participants in this study expected to learn mathematics by "conceptual learning" and the authentic applications of mathematics, they experienced rote-and-drilling-dominated learning approaches in mathematics education, which had succeeded in developing their numerical senses and problem-solving skills but failed to develop their sense of creativity and positive attitudes toward mathematics. The practical mentality and the examination-oriented culture in Hong Kong were the perceived factors that caused such situations.香港學生於不同的國際數學評測中都表現優越，但他們對學習數學並未展現出相應的態度。本研究探討10名香港中六學生對學習數學的看法。研究員對學生的訪問回應進行了內容分析，從中了解阻礙學生發展出對學習高中數學課程的良好態度的因素。學生雖然期望能透過概念學習和應用數學於日常環境來學習數學，但他們總是經歷死記硬背及不斷操練的方式來學習。此方式或許能有效發展學生的數感和解難能力，但未能幫助他們建立創意和良好的數學態度。務實心態和應試文化是學生最重視的因素。 Copyright © 2022 香港中文大學香港教育研究所.

By considering the example of proving the triangle postulate, this study aimed to explore Hong Kong preservice and novice teachers' knowledge competencies and their beliefs about preformal and formal proofs. The findings revealed that such teachers are not proficient in using preformal proofs and do not realize that preformal proofs are a useful tool for connecting abstract geometrical concepts with concrete meanings. We conclude by providing strategies for teachers to use preformal proofs effectively in their teaching of geometric propositions.
