多媒體教室主要有哪些設備?

2019-06-28

多媒體教室是指在教學過程中,根據教學目標和教學對象的特點,通過教學設計,合理選擇和運用現代教學媒體,并與傳統教學手段有機組合,共同參與教學全過程,以多種媒體信息作用于學生,形成合理的教學過程結構,達到較優化的教學效果。多媒體是現代教育以計算機、投影儀、幻燈、展示臺、錄像、廣播、電影、電子白板、計算機 等現代教育技術教育不可缺少的設備概念,運用現代教育理論和技術,通過對教學過程和資源的設計、開發、應用、管理和評價,以實現教學現代化的理論與實踐。

一、含有以下設備:中控主機、投影機、納米黑板、交互式一體機、電腦(可選項)、IP廣播、音響等多種設備。一個標準多媒體視聽教室,基本上應包含多媒體計算機系統、投影顯示系統、數字視頻系統、音響設備、環境設備和集中控制等6大系統組成。

1、多媒體計算機系統:既可以直接進行計算機教學、培訓和演示,也可以通過各種軟件來制作不同學科的教學資料,計算機系統可以使用臺式機,也可使用筆記本電腦。

2、投影顯示系統:由高亮度、高解析度的多媒體液晶投影機(或納米黑板)、視頻展示臺、投影屏幕等組成,完成對各種圖文資訊的大屏幕顯示。

3、數字視頻系統:主要包括影音播放設備如VCD、DVD、高清跟蹤攝像機、錄音機等。

4、音響設備:主要由會議擴聲系統和多媒體音視頻系統組成。包括IP廣播、傳聲設備如麥克風,無線麥克風系統,擴聲設備如功放、音箱,有的學校還加有調音設備如調音臺、混響器等。實現多媒體電教室的現場擴音、播音,配合大屏幕投影系統,提供優良的視聽效果。

5、環境設備主要指可調燈光、電動窗簾、空調設備等,以保證良好的教學環境。

6、中央集中控制系統是結合計算機技術、網絡技術新成果,將整個多媒體教室中的全部媒體設備都由中央控制系統集中管理控制。它的很大的特點就是讓復雜繁瑣的操作過程簡單化,讓使用者在使用各種設備的過程中輕松、從容。通過多年的發展和使用,集中控制的觀念已被教師們所接受。中央集中控制系統已經成為多媒體電教室不可或缺的設備。

二、在選擇控制系統時應注意以下幾個方面 

1、首先系統要穩定可靠。安裝控制系統的目的為了簡化操作,讓老師能輕松自如控制各種設備,達到事半功倍的效果,如果系統不穩定不僅不能簡化操作,反而會影響老師教學效果。因此在選擇是應把質量放在第一位而不是價格。 

2、其次要注意系統的開放性和兼容性。安裝簡單、升級容易,添加、更換設備不麻煩;控制界面簡單明快、邏輯清楚,操作方便、快捷。

3、最后應注意要有多種控制操作方式。目前大多數控制系統均有觸摸屏、軟件、手動控制面板和手持遙控器。學校老師的計算機操作水平是不一致的,有些老師對計算機操作不熟,可以使用手動控制面板。有了遙控器,老師離開講臺后,同樣可以輕松自如的控制各種設備。

綜上所述,要建立一個完整的多媒體電教室,它應該涉及到聲、光、電等各個方面,應充分考慮老師在使用過程中的問題,一方面既要考慮到學校的資金狀況。另一方面要考慮到老師的實際操作情況,簡單、快捷、方便,要讓對計算機使用不太熟悉的老師在教學中敢于使用多媒體設備,提高使用效率,達到事半功倍的效果。如果為多媒體教室配置所選的電教設備不完全符合實際需要的,不但造成資金的浪費,還會令設備冗余。因此,在構建學校多媒體教室時要確定多媒體教室需要哪些設備,應從實際需要出發,盡量符合"少而精"的配置原則。如配置影音系統時,在多功能廳或大型會議廳,調音臺是否必需設備,但單間綜合電教室需要考慮有無必要配置調音臺等音響效果設備。

三、一個標準的多媒體教室設備投入

1、多媒體中央控制系統(中控主機+控制軟件,1000-5000不等時功能而定)。

2、投影機(8000左右,太便宜的效果不好,并且燈泡使用時間短)。

3、投影幕布(800左右,根據教師選擇120寸或更大)。

4、投影吊架(100左右,有的直接送)

5、多媒體智能講臺(1000-2000左右,現在一種鋼制講臺,貴一點,但很好用)

6、電腦一套(3000-5000,自己選擇)

7、功放一臺(800-2000左右)

8、音箱一對(500左右)

9、可選配件:,無線話筒或吊麥一套(500-800左右)

上面是很普通的一個多媒體教室的基本配置,如果要求高或預算不多,可根據情況增減部分設備。更先進的多媒體教室可以選擇用互動一體機(可不需要投影機),還有帶觸摸功能的納米黑板,可以實現投影圖像的互動(價格稍微貴一點)。
