A secondary school physical education teacher uses a Web site to keep parents informed about key activities. What purpose does this technology primarily serve?

The use of a website to keep parents informed about key activities primarily serves the purpose of communication and enhancing student learning. By providing a platform where parents can access important information, updates, and resources related to their children's physical education, the teacher facilitates a crucial connection between home and school.

Effective communication with parents helps to foster an understanding of the curriculum and activities, which can lead to increased engagement and support for students' health and physical education. This involvement can positively influence students' attitudes towards physical activity and foster a supportive environment for learning. By enhancing communication in this way, the teacher is effectively enriching the educational experience of the students.

Other options might seem related, such as increasing student participation or reducing paperwork, but they are secondary to the core function of enhancing communication and learning through direct engagement with parents and guardians. This aspect of communication is key to building a supportive educational community that benefits students' overall learning experiences.
