| At present, our core philosophy of the new curriculum reform is to cultivate students’ scientific literacy, and in three dimensions, including attitudes and values, processes and methods, knowledge and skills to achieve teaching objectives. Knowledge can be receptive by learn to get, but the values, attitudes, skills and methods are hard to come by teaching indoctrination, only the establishment of learner-centered learning environment, providing practical activities scene, before they can reach the New Curriculum Teaching the three-dimensional object.Current research situation of domestic chemistry teaching model focused on "Chemical<Required 1>" and "Chemical<Required 2>" relevant content, there is rarely found in research on teaching elective "Chemistry and Technology," the situation. In addition, research and exploration in the context of teaching theory has been more in-depth and systematic study, but teaching cases and situations specific situations gathering material remains to be further studied.In this paper, according to the new curriculum standards advocated by the "development of students’ ideas, theoretical guidance is situated cognition and learning theory and construct learning theory, on the basis of previous studies have been made on the results of the chemical situation teaching conducted a preliminary exploration. For the teaching content "Chemistry and Life" module focuses on the use of chemical facts, science stories, experiment, create situations of daily life issues, combined with the multimedia technology in the teaching process, created to help students thinking and practice of active scene, promote the comprehensive development of the individual student.This paper is divided into the following five sections:The first part, as an introduction to explore the issues raised in the background, the research purpose, significance and methods. Implement situation teaching is to ask the new chemistry curriculum standards and new Concept, is elective, "Chemistry and Technology" course content requirements, or the students ’interest in learning, to enhance students’ scientific literacy needs.The second part of the theoretical basis of this paper to make a note, paper situation, contextual teaching and teaching situations and other related concepts made a detailed definition and a brief description of the role of these theories in this paper from the guidance, such as the construct learning theory, situated cognition and learning theory, and so the core content.The third and fourth parts, specifically discusses the practice of implementing the teaching situation, the two parts of the core content of this paper is to analyze the current situation, "Chemistry and Technology" situation teaching, characteristics of teaching situation, situation teaching and ideas create scenarios, illustrating the method of teaching situations and cases. In order to make this paper has more targeted and effective, and I designed the "Chemistry and Technology" situation teaching status questionnaire. Based on the findings, Xi’an, selected key high school high and one (1) class and high school (2) classes for the study, conducted situation teaching quiz. At the same time before and after the experiment, respectively, the experimental classes and control classes of students interested in learning chemistry questionnaire, and statistics and analysis of the two classes of chemical results.The fifth part, the basis of the previous four-part discussion, summarize the conclusions of the Institute. |
