The editorial above provides us a problem solving strategy after the information collecting and certain analysis 分析:1、促銷策略提出的前提是前兩年銷售量的下降。
3 . how to select problem solving strategy and which to select greatly affect high school students " chemical problem solving's quickness and accuracy 怎樣選擇問題解決策略和選擇怎樣的策略解決問題,對(duì)于快捷、正確地解決中學(xué)化學(xué)問題有著重要影響。
(2 ) the majority of senior middle school students have not mastered the effective organization strategy and problem solving strategy and they are not good at using social strategy (2)大多數(shù)高一學(xué)生未掌握有效的組織策略和問題解決策略,不善于運(yùn)用社會(huì)性策略。
Being armed at the characters of variant design for complex mechanical products, the combination of case-based reasoning ( cbr ) and rule-based reasoning ( rbr ) is adopted as the problem solving strategy . the implementation technology of cbr is deeply researched on 針對(duì)復(fù)雜機(jī)械產(chǎn)品變型設(shè)計(jì)的特點(diǎn),采用了基于實(shí)例的推理(case-basedreasoning,簡(jiǎn)稱cbr)和基于規(guī)則的推理(rule-basedreasoning,簡(jiǎn)稱rbr)相結(jié)合的問題求解策略。
The objects of this article are high school students in jiangsu province, and we've based on the high school chemical problem solving, using reference analysis, questionnaire investigation, sample analysis and think-aloud method etc to study the current situation of students " chemical problem solving, investigate the process and features of students " chemical problem solving and analyze the problem representation and the action in problem solving strategy application in the course of students " problem solving 本文以江蘇地區(qū)的高中學(xué)生為研究對(duì)象,以中學(xué)化學(xué)問題的解決為研究載體,利用文獻(xiàn)分析法、問卷調(diào)查法、個(gè)案分析法、出聲思維法等研究方法,了解中學(xué)生化學(xué)問題解決的現(xiàn)狀,研究中學(xué)生化學(xué)問題解決的過程和特點(diǎn),分析學(xué)生問題解決過程中的問題表征和問題解決策略應(yīng)用中的行為。
The paper surveyed the historical origin of the idea and the backgrounds of the rise of the learning strategy research, and reviewed some facets such as its concept, structure, feature and teaching; the paper investigated and analyzed the present status of the learning strategy, the learning habits and the thinking process of problem solving of senior middle school students; the paper also committed a theorical and practical study about the instruction and training of chemistry concepts learning and problem solving strategy in senior middle school students 文章追述了學(xué)習(xí)策略思想的歷史淵源,學(xué)習(xí)策略研究興起的時(shí)代背景,對(duì)學(xué)習(xí)策略的涵義、結(jié)構(gòu)、特征、學(xué)習(xí)方法、學(xué)習(xí)策略的教學(xué)等進(jìn)行了綜述;對(duì)高一學(xué)生學(xué)習(xí)策略的應(yīng)用現(xiàn)狀、學(xué)習(xí)習(xí)慣及解題思維過程進(jìn)行了調(diào)查分析;對(duì)在高一化學(xué)中實(shí)施化學(xué)概念學(xué)習(xí)策略和化學(xué)解題策略的教學(xué)與訓(xùn)練進(jìn)行了理論及實(shí)踐研究。
Here a suggestion is presented that the mental process of senior chemistry experimental problem-solving can be divided into four periods such as problem confirming, problem parsing, experiment design and experiment operation, and there are six representation patterns of chemistry experimental problem, for instance, character representation, chemistry representation, sample representation, visualization representation, skill representation and mathematic representation . at the same time, problem solving strategies also can be divided into principle guide, sample guide, environment guide and blind attempt 作者提出高中學(xué)生解決化學(xué)實(shí)驗(yàn)問題的心理過程可分為問題確認(rèn)、問題解析、實(shí)驗(yàn)設(shè)計(jì)和實(shí)驗(yàn)操作四個(gè)階段,他們對(duì)化學(xué)實(shí)驗(yàn)問題的表征方式有字面表征、化學(xué)表征、樣例表征、形象表征、技能表征和數(shù)學(xué)表征等六種,而解決策略則可分為原理導(dǎo)向、樣例導(dǎo)向、情境導(dǎo)向和盲目嘗試四種。
2 . this paper proposes agent-based imis after a careful study of imis, designs system architecture, and the innate structure and conceptualization of agent, discusses in detail the implementation procedure and methodology . based on previous research related with agent, this paper suggests agent-based imis coordination method, complex problem solving strategy and agent " s communication mechanism 通過對(duì)智能管理信息系統(tǒng)的系統(tǒng)分析,提出基于agent技術(shù)實(shí)現(xiàn)智能管理信息系統(tǒng)的方法,設(shè)計(jì)整個(gè)系統(tǒng)的體系結(jié)構(gòu)和agent的內(nèi)部結(jié)構(gòu)并給出agent的定義,分析了整個(gè)系統(tǒng)的設(shè)計(jì)實(shí)現(xiàn)的過程與方法,研究了管理信息系統(tǒng)中agent之間的協(xié)調(diào)機(jī)制、復(fù)雜問題的求解機(jī)制和多agent系統(tǒng)的通訊機(jī)制。
