Second, short answer questions (this big question is 2 small questions, 2 1 question 12 points, 22 questions 13 points, a total of 25 points)
2 1. In the curriculum standard, the goal of chemistry is to develop students' ability. The right figure shows the solubility curve (the solubility curve of sodium chloride and potassium nitrate is 60 g at 60℃) (1). What information can you get from the correct picture?
(2) Please briefly describe the advantages of using charts in chemistry teaching.
22. Materials: Chemical concept learning can include concept formation strategy, concept assimilation strategy and concept map strategy. The concept formation strategy includes three stages.
(1) Take the law of conservation of mass as an example, briefly describe the application of concept formation strategy.
(2) Briefly describe the main contents of concept assimilation strategy and concept map strategy.
Third, the diagnosis question (this big question is 1, and the score is 15)
23. A class of students use the device shown in the figure to measure the oxygen content in the air. After the experiment, student A's water level in the jar is obviously less than 1/5 of the air volume in the jar, and student B is obviously greater than 1/5 of the air volume in the jar. The following explanation of these two phenomena is reasonable ().
(1) A student may not use enough red phosphorus and the oxygen in the bottle is not used up.
(2) A student may not plug the cork, and the outside air enters the bottle when the red phosphorus is extinguished and cooled.
(3) Student B may not have clamped the spring clip, and part of the air in the bottle escaped from the conduit when the red phosphorus burned.
(4) Student B may insert the burning spoon too slowly, and some air will escape from the bottle when heated before the cork is plugged.
A.①③ B.③④ C.①②③ D.①②③④
(1) What should I choose for this option?
(2) Why did the students choose the wrong one? Please analyze them one by one.
(3) What knowledge and skills did the students learn?
Iv. Case analysis (this topic 1 subtopic, 20 points in total)
24. The students studied molecules and atoms in physics. The teacher asked them to recall. Three students said that one student said that it might be the fragrance of flowers, one was diffusion, and the third was that two lead blocks would melt together if they were put together for a long time. The teacher led them to do three experiments, experiment 1: add ammonia water to the water with a beaker; Experiment 2: adding ammonia water and phenolphthalein into a beaker filled with water; Experiment 3: Cover two small beakers with a big glass cover. One beaker contains concentrated ammonia and the other beaker contains phenolphthalein solution. Then the teacher and students concluded that molecules are constantly moving and there are gaps between them. Some students asked: why do you cover two small beakers with a big glass cover, one of which changes color and the other does not? The teacher advised the students to consult the materials after class.
(1) What are the positions of molecules and atoms in chemistry teaching?
(2) What is the teacher's role in doing three groups of experiments? What kind of scientific methods did the teacher use?
(3) What teaching philosophy did the teacher use?
