摘要

本研究的目的是分析学生解决以符号和数字表示的线性运动运动学问题的能力。研究采用横断面设计调查法。研究对象包括玛琅一所州立大学物理学专业的26名一年级本科生，其中包括10名男性和16名女性。研究工具是用符号和数字表示的线性运动运动学问题的开放式检验，可靠性为0,807。研究数据使用描述性和非参数推理统计进行分析。结果表明，学生对线性运动运动学问题的符号化和数值化解题能力一般。学生们在用符号和数字表示解决物理问题时都有困难。研究还发现，对于学生来说，符号表示的线性运动运动学问题比数字表示更难解决。该研究建议进一步研究，以更真实地探索学生困难的原因，例如通过面试或自言自语。

The ability to solve physics problems in symbolic and numeric representations

The aim of this study is to analyze the ability of students to solve the problems of linear motion kinematics expressed in symbolic and numeric representation. Research was survey with cross-sectional design. Research subjects included 26 first year undergraduate students in physics at one of the State Universities in Malang which was consisted of 10 men and 16 women. The research instrument was open-ended test of linear motion kinematics problems expressed in symbolic and numeric representations with a reability of 0,807 The research data were analyzed using descriptive and non-parametric inferential statistics. The results showed that the ability of students to solve linear motion kinematics problems in both symbolic and numeric representation was medium. Students had difficulty solving physical problems in both symbolic and numeric representations. It was also found that the problems of linear motion kinematics in symbolic representations were more difficult for students to solve than numeric representations. The study suggested further research to explore the causes of student difficulties more authentically, e.g. by interviewing or thinking aloud.

期刊介绍： The Revista Mexicana de Física (Rev. Mex. Fis.) publishes original papers of interest to our readers from the physical science com unity. Language may be English or Spanish, however, given the nature of our readers, English is recommended. Articles are classified as follows: Research. Articles reporting original results in physical science. Instrumentation. Articles reporting original contributions on design and construction of scientific instruments. They should present new instruments and techniques oriented to physical science problems solutions. They must also report measurements performed with the described instrument. Reviews. Critical surveys of specific physical science topics in which recent published information is analyzed and discussed. They should be accessible to physics graduate students and non specialists, and provide valuable bibliography to the specialist. Comments. Short papers (four pages maximum) that assess critically papers by others authors previously published in the Revista Mexicana de Física. A comment should state clearly to which paper it refers.
