据笔者统计,科学学科中,学生探究实验课占了总课时的半数以上。动手探究实验能有效激发学生爱科学的兴趣,培养其探究能力,提高科学素养。近几年来,随着课程改革的日益深入,我们注重了学生学习科学的过程,努力构建一种探究的过程,让学生变被动为主动。学生经历发现问题、提出问题、做出猜测与假设、设计实验、进行观察作出记录、进行数据分析、得出结论、科学应用诸多过程。这都是符合新课改精神的,是科学课公认的教学模式。然而,笔者观察了许多公开课、优质 According to the author’s statistics, scientific research, students explore experimental class accounted for more than half of the total class hours. A hands-on exploration experiment can effectively stimulate students’ interest in science, develop their inquiry skills and improve their scientific literacy. In recent years, with the deepening of curriculum reform, we have focused on students’ learning of science and strive to establish a process of inquiry so that students become passive and active. Students experience problems, ask questions, make assumptions and assumptions, design experiments, make observations and make records, analyze data, come to conclusions, and apply many processes in science. This is in line with the spirit of the new curriculum reform, which is a recognized teaching mode in science class. However, I observed many open classes, high quality
