Common Acid and Alkali Class 2 Teaching Reflection
Acid and base were two common substances in chemistry. In the teaching of "Common Acid and Base" lesson 2, the following aspects were worth reflecting on. In terms of teaching methods, it was more appropriate to use the combination of teacher's enlightening explanation and student's experimental exploration. Teachers should play the role of organizer, guide, and collaborator, guiding students to think and guide experimental exploration. For example, in the experimental exploration segment, students should be guided in the experimental plan, and the students should be standardized in the experimental process and guided to observe the phenomenon correctly to ensure that the students could completely and accurately describe the experimental phenomenon. This would help to cultivate students 'rigorous scientific attitude. At the same time, in terms of the cultivation of students 'emotions, attitudes, and values, the results of the students' experiments should be encouraged or guided in a timely manner, so that the students pay attention to the scientific methods in the experimental process. For the content of the teaching materials, setting different knowledge points according to the situation was an effective teaching method. For example, using stories or life scenes to introduce new lessons, such as using the story of " The Witch's Trickery " to set up suspense and introduce the knowledge of acid and base with common sense of daily life, could stimulate students 'interest. When exploring the acid and base properties of substances, games were used. Some students played different substances, while others played indicators to carry out experiments. The images were vivid and the students 'main position was highlighted. In terms of specific teaching content, the physical properties of concentrated sulfuric acid and concentrated sulfuric acid could be demonstrated by the teacher, especially when the weather was cold. The phenomenon of white fog at the mouth of the concentrated sulfuric acid bottle needed to be observed carefully by the students. As for the characteristics of concentrated sulfuric acid, students could understand its corrosiveness by showing pictures of hurting people, and then show the harmful scene of improper thinning of concentrated sulfuric acid through the textbook to guide students to think about the rational use of acid and master the correct thinning steps. As for the chemical properties of dilute sulfuric acid and dilute sulfuric acid, the students were first asked to carry out exploratory experiments in groups to understand their chemical properties and write chemical equations. Then, they would consolidate their knowledge through discussion, induction, and practice. During this process, they would design contrast experiments to deepen the students 'understanding of knowledge. For example, the contrast experiment of three different metals reacting in the same acid, the contrast experiment of the same metal reacting with dilute sulfuric acid and dilute sulfuric acid, etc. Read more exciting novels for free
