The use of information and communication technologies in the process of learning through technological resources can be strongly motivating for students. The use of appropriate digital content through simulations and animations can facilitate the understanding of complex content. In this work, the incidence of the use of technological devices by students of the mathematics subject in Secondary Education in Madrid (Spain) is presented. Specifically, in relation to the use of an explanatory video made with the Camtasia application. The sample was of 31 students with a low level of competence in the subject. A quasi-experimental method of pretest/posttest design was used through an experimental group and a control group. Specific materials were designed and produced for this research. All these materials were subjected to expert judgement. The results show that the use of the instructional video was more than positive in the different variables under study.

技术资源对高中数学能力发展的影响

在通过技术资源进行学习的过程中使用信息和通信技术可以极大地激励学生。通过模拟和动画使用适当的数字内容可以促进对复杂内容的理解。在这项工作中，介绍了马德里（西班牙）中学数学专业学生对技术设备的使用情况。具体而言，关于使用Camtasia应用程序制作的解释性视频。样本来自31名在该学科中能力低下的学生。通过实验组和对照组采用准实验的前测/后测设计方法。为这项研究设计和生产了特定的材料。所有这些材料均经过专家判断。
