簡介：中文中文5130字簡介本文就高等院校的體育教育質量管理系統(tǒng)的現狀和發(fā)展策略的實施展開簡介本文就高等院校的體育教育質量管理系統(tǒng)的現狀和發(fā)展策略的實施展開了深入的探索和研究，從其基本特征、目前的實施情況以及影響因素等方面，了深入的探索和研究，從其基本特征、目前的實施情況以及影響因素等方面，調查分析了高等院校的體育教育質量管理系統(tǒng)，并分析了普通高等院校的體育調查分析了高等院校的體育教育質量管理系統(tǒng)，并分析了普通高等院校的體育教育質量管理系統(tǒng)的運行子系統(tǒng)，同時結合子系統(tǒng)來調查現狀來進行最優(yōu)設教育質量管理系統(tǒng)的運行子系統(tǒng)，同時結合子系統(tǒng)來調查現狀來進行最優(yōu)設計。本文還進一步提出了發(fā)展策略的建議，為該領域未來的探索和研究提供了計。本文還進一步提出了發(fā)展策略的建議，為該領域未來的探索和研究提供了參考。參考。關鍵詞高等院校；體育教學；教育質量管理關鍵詞高等院校；體育教學；教育質量管理對于改革和發(fā)展高等教育而言，建立和發(fā)展教育質量管理系統(tǒng)非常必要。高等教育質量的核心是人才培訓的質量，任何領域的人才培訓均以良好的身體及精神健康作為先決條件。因此，在高校建立一個有效的體育教育質量質量管理體系為輸送社會建設人才和培養(yǎng)一生的體育鍛煉習慣提供了堅實的保證。一．高等院校的體育教育質量管理體系的現狀高校體育教育質量管理體系的總體發(fā)展狀況在接受調查的23所高校當中，15所高校實行體育教育質量管理體系，6所高校沒有實行，2所高校準備實行（見表1），實行的高校和沒有實行的高校的比例約為21。表1高等院校體育教育質量管理體系的總體實行情況實行情況實行沒有實行準備實行高校1562比例6522260969調查問卷2683比例702721628111998年，全國高校招收108萬名新生，在校生達340名。到1999年，全國高校招收160萬名新生，比1998年增加520,000名，增長率為47；到2004年，全國高校的在招生數量達447萬，在校生為1333萬；各類高校的總規(guī)模達2千萬，高等教育的毛入學率增長了191,2。在1999年到2004年之勵和發(fā)展社會中介評估組織（例如學科協(xié)會和相關企業(yè)的專家評估團隊等）來積極參與高等院校體育教育質量管理體系的鑒定活動。強化宏觀、中介和微觀管理機構之間的協(xié)調重視高等院校的內部管理部門以形成上下級機構、縱向和橫向組織、水平和交叉線組織之間的互相信任、互相協(xié)調和信息共享。這主要針對國家高等教育行政部門來建立相對的國家級組織和機構，并相繼在高校建立內部信息接收機構、傳輸機構等，以便將所發(fā)布的體育教育質量管理的相關信息源傳輸到下級；在每級組織內部建立信息分享平臺來進行信息的傳輸和交流每個高校必須通過委派資訊主任和其他方式來從高層權威機構接收信息、快速接收信息并準確傳輸到基層組織，同時也便于開展工作。充分發(fā)揮體育教育質量管理主體的主觀能動性充分發(fā)揮體育教育質量管理主體的主觀能動性是有效實行管理體系的關鍵，主要通過培訓管理主體的管理能力，約束訓管理主體的管理行為，提高管理主體（如領導、教師、學生以及相關工作人員等）的可信性和誠實度。約束管理行為是培訓和提高管理主體的管理能力的關鍵補充，也是驅使管理主體發(fā)揮主觀能動性的外力。它從自然意識出發(fā)來培訓體育教育質量管理主體的管理能力該管理能力需在長期的教學當中逐漸形成和培養(yǎng)，因此，它具有可塑性，其培訓應關注長期特征和持續(xù)性。這主要通過加強教育培訓、提高管理意識及提升教師的管理熱情；建立教育場景，訓練并考察教師在教學過程中的敏感性以及學生的學習成果，來提高自我反饋和評估的能力；通過哲學、心理學和其他基本學科來實施學校的基本培訓，訓練管理主體的辯證思維和自省思維能力；與此同時，提高一系列過程的指導工作，如學習、檢查、進步和進一步的自省。約束管理行為并促進體育教育質量管理主體的管理能力的形成管理行為時管理能力的外在表現，因此，在具有一定質量意識的基礎上，通過約束管理行為來進一步促進管理主體的管理能力的形成。通過形成行為準則、監(jiān)督體系和約束機制，來約束領導、管理人、教師和學生中各管理主體的自控行為和相控行為。這主要集中在體育教師在教學準備過程中的管理行為、方式方法的使用以及口頭的和非口頭的交流等具體環(huán)節(jié)7，并通過課堂教學來實施措施。嚴格控制管理主體的可信性和誠實度以保證管理行為的有效性首先，在管理過程中保障該可信性和誠實度，確保管理主體明確可信性和誠實度，并具有可信性和誠實度的意識；對管理和服務工作人員，定期檢查其可信性和誠實度，及其可信性和誠實度的記錄和評估；通過加強典型榜樣教育、示范教育和廣泛宣傳，創(chuàng)造一個教師可信性和誠實度的良好

簡介：1大學生自我職業(yè)生涯規(guī)劃探析摘要職業(yè)規(guī)劃是人力資源管理領域的重要課題之一，職業(yè)規(guī)劃是個人發(fā)展的主體需要，一個人要成就一番事業(yè)就必須有對自身清醒的認識和明確的人生規(guī)劃；同時個體的職業(yè)規(guī)劃又是整體社會發(fā)展的客觀要求，大學生是社會構成的特殊群體，更是推動社會進步的生力軍，這一群體是否有明確的職業(yè)生涯規(guī)劃，能否在激烈的社會競爭中找到合適的位置貢獻自己的力量，具有非常重要的現實意義。而我國針對大學生的職業(yè)規(guī)劃教育和研究才剛剛起步，在機構和服務上都遠遠滿足不了需求，所以大學生提高自我職業(yè)規(guī)劃意識，積極的進行自己的人生規(guī)劃是很有必要也是迫在眉睫的。以下論述在導師悉心的指導下，相應借鑒文獻資料結合心理測評工具，提出了適合大學生提高自我認知，合理規(guī)劃職業(yè)生涯的理論方法和建議，希望能給當前大學生在職業(yè)生涯規(guī)劃應用方面提供些許幫助。關鍵詞關鍵詞大學生自我認知職業(yè)生涯規(guī)劃ABSTRACTCAREERPLANNINGISANIMPORTANTRESEARCHPROJECTOFTHEHUMANRESOURCESMANAGEMENTTOPICAREA，CAREERPLANNINGISONEPERSONDEVELOPMENTNEEDS，APERSONTOACAREER，YOUMUSTHAVEACLEARANDDEFINITELIFEPLANNING，WHILETHEINDIVIDUALCAREERPLANNINGISTHEOBJECTIVEREQUIREMENTOFTHEDEVELOPMENTOFTHEWHOLESOCIETYCOLLEGESTUDENTSARESPECIALSOCIALGROUP，ANDTHEYARETHEMAINFORCEOFTHESOCIALPROGRESS，THISGROUPHAVECLEARCAREERPLANNING，WHETHERINTHEFIERCECOMPETITIONINTHESOCIETYTOFINDASUITABLELOCATIONTOCONTRIBUTETHEIRSTRENGTH，HASVERYIMPORTANTPRACTICALSIGNIFICANCEANDOURCOUNTRYACCORDINGTOTHECOLLEGESTUDENTSEDUCATIONANDRESEARCHOFCAREERPLANNINGHASJUSTSTARTED，THEORGANIZATIONANDTHESERVICEISCANTSATISFYTHEDEMAND，SOSTUDENTSIMPROVESELFAWARENESS，MAKECAREERPLANNINGFORHISLIFEOFACTIVELYPLANNINGISVERYNECESSARYANDIMMINENTFOLLOWINGTHETEACHERCAREFULLY，UNDERTHEGUIDEOFCORRESPONDINGREFERENCELITERATURECOMBININGPSYCHOLOGICALEVALUATIONTOOLFORCOLLEGESTUDENTS，ANDPUTSFORWARDIMPROVINGEGOCOGNITION，RATIONALPLANNINGCAREERTHEORYMETHODSANDSUGGESTIONS，IHOPINGINCAREERPLANNINGAPPLICATIONSITCANPROVIDESOMEHELPFORCOLLEGESTUDENTSKEYWORDSUNDERGRADUATESCAREERPLANNINGSELFPERCEPTION1前言大學時代是精彩人生的黃金起點，現代文明的今天，為大學生提供了實現人生理想與價值的機會和空間，同時也提出了更高層次的要求與挑戰(zhàn)。我國高校經過擴招，高等教育逐步普及，使每年大學畢業(yè)生幾乎成倍增長，而許多大學生對于走出校門，開始自己的職業(yè)生涯充滿盲目和迷惑，導致‘畢業(yè)等于失業(yè)’、頻繁跳槽現象普遍存在，究其原因，大部分大學生沒有一個明晰的職業(yè)生涯規(guī)劃是很重要的一點。每個人都會有自己的夢想，憧憬著光輝燦爛的未來，向往著如花似錦的前程。面對嚴峻的就業(yè)形勢，如何明確了解自己，認清自己的位置與方向，規(guī)劃適合自己的道路，是每一位大學生值得深思的問題。如果大學生能盡早的進行個人的職業(yè)生涯規(guī)劃，在畢業(yè)時就能有一個合適的選擇方向，在未來職業(yè)生涯中就能充分體現自我價值，大學生應把握機遇，在大學期間對自己的職業(yè)生涯進行科學系統(tǒng)的規(guī)劃，只有明確自己的目標，有針對性的不斷充實與完善自己，才能把握鍛煉自己塑造自己的每一次機遇，才能謀求一個令自己充滿活力的發(fā)展空間，為夢想插上翅膀，在未來的天空中自由翱翔。在21世紀經濟與科技高速發(fā)展的今天，人力資本無可爭議的成為企業(yè)乃至國家在競爭中保持優(yōu)勢的關鍵，而大學生正是企業(yè)和國家人力資本大軍的后續(xù)隊，大學生規(guī)劃科學明確的職業(yè)生涯，不僅對自己人生發(fā)展有著導向的作用，而且對優(yōu)化整個國家的人力資源結構推動社會進步發(fā)展也有著重要的意義。下文將對大學生提高自我認知，進行合理職業(yè)生涯規(guī)劃方面提出粗淺的認識，旨在幫助大學生以自己的實際行動，認識自己了解自己，做出合理的職業(yè)生涯規(guī)劃，為自己未來的發(fā)展打下良好的基礎，可以充分實現自身價值，為社會做出應有的貢獻。1大學生職業(yè)生涯規(guī)劃概述職業(yè)生涯規(guī)劃學說起始于20世紀60年代，作為人力資源管理理論的重要內容之一，職業(yè)生涯規(guī)劃專業(yè)研究是在美國興起的，隨后又被引入到其他歐美國家，并得到了快速發(fā)展。20世紀70年代在美國又興起了職業(yè)生涯規(guī)劃教育，許多高校開始著眼于為
