摘要近几十年来，科学概念的学习过程在许多研究中得到了研究和讨论。然而，对这一过程的理解可能会有所不同，这取决于所采用的心理教育方法。从概念轮廓的角度来看，同一个概念可以代表一种以上的思维模式和说话方式，然后可以组织成不同的区域。在这项研究中，我们报告了共价键的概念概况，它考虑了认识论和本体论的承诺。为此，我们进行了一个叙述性的概念的历史发展回顾，以及在文献中报道的化学键的误解进行了系统的回顾，并采用了问卷调查，以高等教育类化学。结果以语义矩阵的形式进行了汇编，其中包含19个含义，然后将其转化为四个区域：无差别连接，稳定吸引力，局部残留和系统性离域。该提案有助于讨论解释所研究内容的方法，特别是在化学教学中，考虑到其在学生学习中的多义性和演变。此外，它允许未来的教学单元和文本分析的规划。
ABSTRACT The learning process of scientific concepts has been investigated and discussed in several studies in recent decades. However, the understanding of this process may be different depending on the psycho-pedagogical approach adopted. From the perspective of the conceptual profile, the same concept can present more than one mode of thinking and way of speaking, which can then be organised into different zones. In this study, we report a conceptual profile of the covalent bond, which contemplates epistemological and ontological commitments. To this end, we conducted a narrative review of the historical development of the concept, as well as a systematic review of the misconceptions of chemical bond reported in the literature, and applied a questionnaire to a higher education class in Chemistry. The results were compiled in the form of a semantic matrix with nineteen meanings, which was then transformed into four zones: indiscriminate connectivity, stabilising attractiveness, localised remnant, and systematic delocalisation. The proposal contributes to the discussion of the approaches that explain the content under study, specifically in the teaching of chemistry, by considering its polysemy and evolution in the students’ learning. Additionally, it allows the future planning of teaching units and textual analyses.
