The purpose of this study was to determine the effect of the use of calculators on the responses of undergraduate nursing students to items on a dosage calculations examination. The study sought to determine if calculator use had any influence on both the arithmetic and conceptual skills associated with the solving of calculations problems. The population consisted of all students enrolled in a pharmacology course in a baccalaureate nursing program. An experimental repeated measures design was used in which all participants completed two parallel forms of a calculations examination, one form with a calculator and one form without a calculator. Findings of the study revealed that there was significant difference in both arithmetic and conceptual skills ability using a calculator. Use of a calculator was associated with improved arithmetic skills performance and diminished conceptual skills performance. A major factor underlying both arithmetic skills and conceptual skills performance, independent of the calculator effect, was the pre-admission arithmetic skills ability of the subject.
本研究的目的是确定使用计算器对本科护理专业学生在剂量计算考试中答题的影响。该研究旨在确定使用计算器是否对与解决计算问题相关的算术和概念技能有任何影响。研究对象为所有参加本科护理专业药理学课程的学生。采用实验性重复测量设计，所有参与者完成两种平行形式的计算考试，一种形式使用计算器，另一种形式不使用计算器。研究结果表明，使用计算器在算术和概念技能能力方面存在显著差异。使用计算器与算术技能表现的提高和概念技能表现的下降有关。独立于计算器效应之外，算术技能和概念技能表现的一个主要因素是受试者入学前的算术技能能力。
