Secondary School Science And Technology Activities, Lesson Teaching Mode And Evaluation System

Technological Activity Lesson" is one of kind of "Activity course", Itsaim is to raise scientific quality of students in middle and elementary school,including: scientific and culture quality, scientific consciousness, scientificmethod, scientific process and creation spirit. Because this kind of lesson wasjust offered in China as well as overseas, there is not a systematic expositionabout its teaching mode and estimation method.In this paper, by wholly holding the course system of "TechnoloicalActivity Lesson", integrating the achievements from "constructivism"teaching theory of J Piaget, cognition psycholo y, creation psychology,information theory, epistemology, system theory, t~e theory foundation orthe teaching mode of "Technological Activity Lesson" was thoroughlyanalyzed, and on the base of the concept of teaching mode, some factors, suchas the framework, characteristics, operation procedure, remark principle, werediscussed in this paper. According to the results from experiment in fourmiddle schools at Guiyang in grade one and grade two for entire an academicyear, a new teaching mode an classroom teaching estimation standard for the"Technological Activity Lesson was suggested. Its teaching mode wasmainly showed as following:A.Framework of The Modea.Topic Factor: The subject education thought, success educationiii(C-Abstractthought, character education thought in whole technological activities.b.Target Factor:Emotion target Learn how to care for others, take part in activity,cooperate, develop himself.Ability target Develop some ability, such as how to consider andsolve problem in independent, operate,investigate, research, create, communicate,manage and so on.Knowledge target Utilize knowledge Synthetically, innovative anderudite in knowledge.c. Condition factor: All kinds of teaching condition before class.d. Procedure factor: It is a performance successively sequence thatorganizes teaching activity by use of mode.The main procedure was the "Preparationbefore class Circumstance question show -Guidance and conception Hint andteach to creation Assess and feedback inClass" . Moreover, there were some sub-sequences according to different lessons.2. Estimation factor:c Estimation principle ---- Principles about Scientific nature andObjectivity, Practice nature and Creativity,Independence and Oriented, Qualitativeanalysis and Quantitative analysis,Synthetic and Open, Overall.QEstimation contentsAt stage before class: preparation about materials and spirit.At stage during activity procedure:Circumstance stimulation (Target invert --- perceive newknowledge) Activity case(The case of that the studentspositively study and investigateon their own initiative, co-operate with others to learn, thecase of that teachers teach andinstruct students, the case ofthat students associate ofthought and creation for newidea, they do something notonly by hands but also withbrain etc.)At the stage of activity effect:Contrast and communication,deduction and sum up, find updisparity and select the best.R Estimation way ---- Students estimate by themselves, bycombining with students and byteachers.cEstimation index ---- The index was determined according toestimation list of classroom teac inmode, estimation items, estimation theiv4main points and mark value.cEstimation functionDiagnose ?Guidance ?Excitation --Trend.Characteristics of mode in educationa.Put enlighten and investigate learning in first place.b.Alternate learning.c.Multi-course knowledge intercross solution and creative learning.d.learning with Diversification, personality and cooperation.e.Teacher is the instructor and hinter for student learmng.f.Synthesis Estimation based on acti...
