| Scientific inquiry is the key content of the new curriculum concept, is the key of the chemistry teaching reform direction..And hand-held technology as a symbol of modern technology into the subject teaching, providing a new thought and method to the traditional teaching activity. Chemistry is based on the experimental subject, With hand-held technology as inquiry experiment in the teaching design of tools to help students establish subject knowledge, And cultivate the students to learn knowledge in the process of learning, to explore the method and develop its own inquiry ability.This research includes two parts content, The first part is the experimental research, the design of two experiments:One is sodium carbonate and sodium bicarbonate of the nature of inquiry experiment, including dissolution when the temperature changes, and the size of the alkaline, and hydrochloric acid reaction speed and thermal decomposition capability, etc. Another is the dissolve of the indissolve electrolyte balance concept establishment, sediment’s transfer and sediment’s change into. Experiments using handheld technology to explore, through the experiment of visual images in the process of rendering to help students understand the content; The second part is the teaching and research, According to the first two parts to explore the reasonable arrangement of the content of the experiment in the teaching design, in the teaching activities, concerned with the problem of students before the experiment to guess and decision;the operation of experiment and observation;after the experiment analysis and conclusion, etc. Let the students find the nature of the problem at the same time and grasp the exploration methods. Handheld technology based on real-time, intuitive, quantitative characteristics is used to explore the teaching, not only make students effective understand the knowledge, control the knowledge, in the process of learning more about their ability to find problems, there is obvious improvement in the ability to solve the problem. |
