Abstract

The aim of this research was the creation and validation of a procedure for determining the cognitive complexity of problem tasks in the field of salt hydrolysis. The procedure created included an assessment of the difficulty of concepts and an assessment of their interactivity. One of the research tasks was to determine whether there were misconceptions by students that might have influenced their achievement. There were 50 Bachelor of Science in Chemistry students who participated in the study. A knowledge test was used as a research instrument to assess the performance and a seven-point Likert scale to evaluate the invested mental effort. The validity of this instrument for the assessment of cognitive complexity was confirmed by a series of regression analyses, where acceptable and statistically significant correlation coefficients were obtained among the examined variables: student performance and invested mental effort as dependent variables and cognitive complexity as independent variable

认知复杂性评估程序：“盐的水解”专题的发展和实施

本研究的目的是创建和验证一种程序，用于确定盐水解领域问题任务的认知复杂性。创建的程序包括对概念难度的评估和对其互动性的评估。研究任务之一是确定学生是否存在可能影响他们成绩的误解。有50名化学理学学士学生参与了这项研究。使用知识测试作为评估绩效的研究工具，并使用七点Likert量表来评估投入的心理努力。该工具用于评估认知复杂性的有效性通过一系列回归分析得到了证实，其中在被测变量之间获得了可接受且具有统计学意义的相关系数：学生表现和投入的脑力劳动作为因变量，认知复杂性作为自变量

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
