Description
Technical Field
The invention relates to a physical teaching method for middle school, in particular to a method for automatically exploring a convex lens imaging rule by students in physical teaching for middle school.
Background
The study of convex lens imaging rules belongs to an experiment which is difficult to teach in middle school physics. On the one hand, the research experiments of the convex lens imaging rules are often developed in a verification experiment mode, and the problem of 'fake research' exists, namely, more teachers tell students how to experiment, how to analyze data and draw conclusions in teaching. Firstly, a teacher introduces a focal length when guiding students to explore the relation between the imaging of a convex lens and the size of an object, so that the students move a light source to the positions of 'u >2f, u=2f, 2f < f, u=f and u < f' to observe the imaging of the convex lens during experiments, and record data; second, when guiding students to analyze data, selecting a position where the object distance is equal to 2 times the focal length as a distinguishing point is usually proposed by a teacher, but it is not explained why 2 times the focal length is selected. The method takes the conclusion as a known condition, and more students are allowed to verify the imaging rule of the convex lens or finish the measuring link under the demonstration of a teacher instead of allowing the students to explore by themselves, so that the autonomous exploration of the students is weakened, and the scientific spirit culture is not facilitated.
On the other hand, students lack a convenient and applicable effective method for analyzing experimental data for exploring the imaging rule of the convex lens. The content required to be recorded in the experiment for exploring the convex lens imaging rule is various, and the quantitative digital recording and qualitative text description are available. Students first encounter this type of experimental data, and it is difficult to take a reasonable and efficient method to process. When students analyze data in actual teaching, a part of students can simulate the previous method for processing experimental data, multiply or add or subtract object distance and image distance, or simply describe the relation between the object distance and the image distance, so that the law of convex lens imaging is difficult to be completely obtained.
The method commonly used by teachers in teaching is to convert monotonically abstract data into 'graphic representation' by adopting an experimental data visualization mode so as to solve the problem that experimental data of a convex lens imaging rule are difficult to analyze. The specific method comprises the following steps: the object and the image are represented by "≡", the positive and the negative of the image are represented by an upward arrow "≡" and a downward arrow "≡", and the size of the object and the image are represented by the length of "≡". Admittedly, the method can solve the problem of complex experimental data of convex lens imaging to a certain extent, so that the method is relatively simple. However, the data table recorded in the observation experiment shows that the property of the image is described by adopting only 'size' in the experiment process, and the actual size of the image is not quantitatively measured, so that the property of the size of the image is difficult to accurately describe in the process of drawing and graphic representation, and the trend of the imaging change of the convex lens is not easy to show. In addition, the manual drawing mode is adopted in the course of the study of the classroom experiment, so that the data characteristics are not convenient to accurately represent, too much time is occupied, and precious classroom teaching time is wasted.

(3) The main purpose of the drawing graphic module is to introduce students how the graphic is drawn and the relation of the graphic features and the corresponding measurement data. After clicking the button "convex lens imaging experimental data graph" by the teacher, the teacher draws the first row of data of the first group of student experimental data (such as drawing the horizontal data with the number 1 in table 1), and sequentially draws the horizontal data with the numbers 1, 2, and 5 in table 1, and the graph is shown in fig. 3, where the content appearing in the graphical interface represents: intermediateRepresenting a convex lens; the area to the left of the convex lens represents the range of movement of the light source, and the area to the right of the convex lens represents the imaging area of the convex lens; inverting the arrow indicates inverting the object or image; the length of the arrow indicates the size of the image; the upper and lower dashed lines are contour lines, and represent positions equal to the object in size, and if the arrow of the image exceeds the dashed line, the position is larger than the object, otherwise, the position is smaller than the object.

Wherein the normal data is the same color (e.g., red), and when the measured image distance is greater than or less than 5% of the calculated image distance value from the current object distance theory, the image distance value is plotted with another color (e.g., pink). The image distance and the image become larger gradually as the object distance becomes smaller through the graphical observation. The more data is collected during the student's experiment, the more the trend is evident. According to the change trend of the diagram, the students are guided to guess whether a certain point exists so that the size of an image is equal to the size of an object, and analysis shows that when the object distance is equal to the image distance, the size of the image is equal to the size of the object, and the object distance is equal to 2 times of focal length, so that teaching of a convex lens imaging rule is continuously completed.

As shown in fig. 5, the light path image and the image of the first group of students at the second experimental object distance are drawn, and the position and the size of the image measured by the students are found to coincide, which indicates that the result measured by the students is more accurate. The student can understand the relation between the convex lens imaging and the focal length of the convex lens conveniently.
(6) Virtual experiments are rules that show convex lens imaging in the form of geometric lines. By clicking the button of the 'convex lens imaging dynamic light path diagram', a teacher can display a virtual convex lens imaging experiment, as shown in fig. 6, click a sliding bar to change the object distance, and the light path diagram and the size and position of an image under the object distance can be drawn. Through the light path diagram, students can understand the law of convex lens imaging real image and complete the teaching difficulty that the object distance is equal to the focal length and does not image. And guiding students to summarize complete convex lens imaging rules by utilizing the light path diagram: the object distance is more than 2 times of focal length, and the object distance is formed into an inverted reduced real image; the object distance is equal to 2 times of focal length, and the object distance is equal to an inverted real image; the object distance is larger than 1 time of focal length and smaller than 2 times of focal length, and the object distance is formed into an inverted reduced real image; the object distance is equal to1 time of focal length, and imaging is not performed; the object distance is less than 1 time of focal length, and the object distance is amplified to form an upright virtual image.
