(2024·南昌市高三一模)
Students and Technology in the Classroom
I love my iPhone — it's my little connection to the larger world that can go anywhere with me. I also love my laptop computer, as it holds all of my writing and thoughts. Despite this love of technology, I know that there is time when I need to move away from these devices and truly communicate with others.
On occasion, I teach a course called History Matters for a group of higher education managers. My goals for the class include a full discussion of historical themes and ideas. Because I want students to thoroughly study the material and exchange their ideas with each other in the classroom. I have a rule — no laptops, iPads, phones, etc. When students were told my rule in advance of the class, some of them were not happy.
Most students assume that my reasons for this rule include unpleasant experiences in the past with students misusing technology. There's a bit of truth to that. Some students assume that I am antitechnology. There's no truth in that at all. I love technology and try to keep up with it so I can relate to my students.
The real reason why I ask students to leave technology at the door is that I think there are very few places in which we can have deep conversations and truly engage in complex ideas. Interruptions by technology often break concentration and allow for too much dependence on outside information for ideas. I want students to dig deep within themselves for inspiration and ideas. I want them to push each other to think differently and to make connections between the course, the material and the class discussion.
I've been teaching my history class in this way for many years and the education reflects students' satisfaction with the environment that I create. Students realize that with deep conversations and challenges, they learn at a level that helps them keep the course material beyond the classroom.
I'm not saying that I won't ever change my mind about technology use in my history class, but until I hear a really good reason for the change. I'm sticking to my plan. A few hours of technologyfree dialogue is just too sweet to give up.
1．Some of the students in the history class were unhappy with ________.
A．the course material
B．others' misuse of technology
C．the author's class regulation
D．discussion topics
解析：选C 细节理解题。根据第二段的最后一句可知，历史课上一些学生不开心的原因是老师定的课堂规则，故选C项。
2．According to the author, the use of technology in the classroom may ________.
A．keep students from doing independent thinking
B．encourage students to have indepth conversations
C．help students to better understand complex themes
D．affect students' concentration on course evaluation
解析：选A 细节理解题。根据第四段的第一、二句可知，作者不让学生在课堂上使用技术设备的原因是担心学生们过于依赖电子技术来获取信息，从而丧失了独立思考的能力，故选A项。
