Student learning activities is an active, full of personality and creative process, students also thinking activities throughout. In the process of learning science in both scientific problems raised, abstract measure, observation of scientific phenomena, scientific model of scientific data, a scientific concept, the establishment of induction and scientific theory of scientific goals, or solve practical problems with scientific theories , they are inseparable from thinking of the students involved. How to make first-year students thinking in science learning activities more effective, more scientific, so as to achieve better teaching results, is the goal of our efforts, but also the purpose of this paper.

The core of teaching is thinking, which is an important part of the cultivation of students' scientific literacy. Students' learning activities are an active, individual and creative process, and students' thinking activities are always carried out. In the process of learning science, the participation of students' thinking cannot be separated from the introduction of scientific problems, the measurement of scientific data, the observation of scientific phenomena, the abstraction of scientific models, the formation of scientific concepts, the induction of scientific goals and the establishment of scientific theories, or the use of scientific theories to solve practical problems. How to make first-year students in scientific learning activities more effective thinking, more scientific, so as to achieve better teaching results, is the goal of our efforts, but also the purpose of this study.

The core of teaching is thinking. For the cultivation of students' scientific literacy, the cultivation of scientific thinking is an important part. Students' learning activity is an active, individual and creative process, and students' thinking activity runs through the whole process. In the process of learning science, whether it is the proposal of scientific problems, the measurement of scientific data, the observation of scientific phenomena, the abstraction of scientific models, the formation of scientific concepts, the induction of scientific objectives and the establishment of scientific theories, or the use of scientific theories to solve practical problems, it is inseparable from the participation of students' thinking. How to make the first grade students' thinking more effective and scientific in scientific learning activities, so as to achieve better teaching effect, is our goal and the purpose of this paper.<br>
