Abstract

Background : Astrometry is a field of study that integrates the procedures necessary to determine the position and movements of celestial bodies, which is why it uses concepts typical of the natural sciences that could be used in scientific education. Objective : To identify scientific concepts related to astrometry in rural secondary basic education contexts. Design : The sequence of activities consisted of Diagnosis of Prior Knowledge , Didactic Intervention , and Assessment . Setting and Participants: 65 students from three rural educational institutions (field schools) of the Department of Boyacá in Colombia participated. Data Collection and Analysis : Two questionnaires were implemented to assess students’ prior concepts and strengthened concepts, which were validated by the judgment of experts in the area. The data was grouped into two categories of analysis: Astrometric Concepts and Astrometric Techniques and Methods . Results: The learning of astrometric concepts such as stellar evolution, parallax, classification, and principles of spectroscopy was favoured, in addition to concepts from physics such as electromagnetic spectrum, brightness, luminosity, temperature-colour ratio, and mathematical concepts, some trigonometric relationships and astronomical units. However, difficulties were evidenced in relation to knowledge of the celestial vault, movements of the stars, and management of astronomical models. Conclusions: The students had little previous knowledge about astrometry, strengthened through didactic intervention, enabling the association of physics, mathematical, and astronomical concepts in the classroom.
野外教学环境下恒星天体测量学教学的教学干预
背景:天体测量学是一个研究领域,它整合了确定天体位置和运动所需的程序,这就是为什么它使用了可以用于科学教育的典型自然科学概念。目的:识别农村中等基础教育背景下天体测量学的相关科学概念。设计:活动顺序包括先验知识诊断、教学干预和评估。项目设置和参与者:来自哥伦比亚boyacac省三所农村教育机构(田间学校)的65名学生参加。数据收集与分析:通过两份问卷对学生的先验概念和强化概念进行评估,并由该领域专家的判断进行验证。数据分析分为两类:天体测量概念和天体测量技术与方法。结果:除了电磁波谱、亮度、光度、温色比等物理概念、数学概念、一些三角关系和天文单位等物理概念外,还有利于学习恒星演化、视差、分类、光谱学原理等天体计量学概念。然而,在天穹的知识、恒星的运动和天文模型的管理方面,困难是显而易见的。结论:学生先前对天体测量的知识很少,通过教学干预加强,使物理,数学和天文学概念在课堂上联系起来。
