如何使用電子白板教學
1、電子白板(ban)需(xu)要(yao)配合投影機、電腦共(gong)同(tong)使用;
2、各設(she)備間物理連接完成(cheng)后(hou),需要(yao)在電腦(nao)上安(an)裝電子白板(ban)程序,進行(xing)定位校準操作,電子白板(ban)就相(xiang)當于一(yi)個大(da)的觸摸屏幕(mu)了(le);
3、電子(zi)白(bai)板有專用(yong)的操(cao)作(zuo)軟件,可以實現對PPT導入、批注、編輯、保存等操(cao)作(zuo),詳見軟件說明即(ji)可;
4、電(dian)子白板根(gen)據感(gan)應(ying)技術不同,實現觸屏(ping)(ping)操(cao)作的方式(shi)有不同,電(dian)磁(ci)(ci)需(xu)要專用(yong)電(dian)磁(ci)(ci)筆進行(xing)(xing)按壓(ya)操(cao)作,壓(ya)感(gan)無需(xu)專用(yong)筆直(zhi)接按壓(ya)操(cao)作,紅外等用(yong)手指等不透(tou)明物(wu)體即可實現觸屏(ping)(ping)功能無需(xu)觸及板面進行(xing)(xing)壓(ya)力感(gan)應(ying)操(cao)作。
電子白板的使用技巧
1、活用白板模式,實現熟練操作
交互式(shi)(shi)(shi)電(dian)子(zi)(zi)白(bai)(bai)(bai)板(ban)(ban)(ban)(ban)的(de)(de)(de)應(ying)用(yong)要在(zai)(zai)控(kong)(kong)(kong)制(zhi)、窗(chuang)(chuang)(chuang)(chuang)口(kou)和注(zhu)(zhu)解(jie)三種模(mo)(mo)(mo)(mo)式(shi)(shi)(shi)下靈活(huo)進(jin)行,熟練掌(zhang)握這三種模(mo)(mo)(mo)(mo)式(shi)(shi)(shi)的(de)(de)(de)特(te)點及切換方(fang)法是(shi)使(shi)用(yong)電(dian)子(zi)(zi)白(bai)(bai)(bai)板(ban)(ban)(ban)(ban)的(de)(de)(de)基礎。電(dian)子(zi)(zi)白(bai)(bai)(bai)板(ban)(ban)(ban)(ban)程序啟動后,默認的(de)(de)(de)是(shi)控(kong)(kong)(kong)制(zhi)模(mo)(mo)(mo)(mo)式(shi)(shi)(shi),在(zai)(zai)控(kong)(kong)(kong)制(zhi)模(mo)(mo)(mo)(mo)式(shi)(shi)(shi)下,電(dian)子(zi)(zi)筆相(xiang)當于鼠標(biao),可(ke)在(zai)(zai)白(bai)(bai)(bai)板(ban)(ban)(ban)(ban)上遠(yuan)距離操作電(dian)腦。通過控(kong)(kong)(kong)制(zhi)模(mo)(mo)(mo)(mo)式(shi)(shi)(shi)下的(de)(de)(de)模(mo)(mo)(mo)(mo)式(shi)(shi)(shi)切換工具能(neng)直接進(jin)入注(zhu)(zhu)解(jie)模(mo)(mo)(mo)(mo)式(shi)(shi)(shi),這時(shi)注(zhu)(zhu)解(jie)模(mo)(mo)(mo)(mo)式(shi)(shi)(shi)的(de)(de)(de)背景(jing)圖(tu)則(ze)是(shi)控(kong)(kong)(kong)制(zhi)模(mo)(mo)(mo)(mo)式(shi)(shi)(shi)中(zhong)顯示的(de)(de)(de)畫面(mian),現在(zai)(zai)方(fang)能(neng)實(shi)現電(dian)子(zi)(zi)白(bai)(bai)(bai)板(ban)(ban)(ban)(ban)的(de)(de)(de)書(shu)寫、繪圖(tu)、編(bian)輯(ji)等強(qiang)大(da)功能(neng)。如果此時(shi)再進(jin)入窗(chuang)(chuang)(chuang)(chuang)口(kou)模(mo)(mo)(mo)(mo)式(shi)(shi)(shi),就(jiu)會(hui)發現窗(chuang)(chuang)(chuang)(chuang)口(kou)模(mo)(mo)(mo)(mo)式(shi)(shi)(shi)中(zhong)并沒有新建一(yi)頁(ye)(ye),而是(shi)以注(zhu)(zhu)解(jie)模(mo)(mo)(mo)(mo)式(shi)(shi)(shi)下的(de)(de)(de)背景(jing)圖(tu)作為頁(ye)(ye)面(mian)背景(jing)。如果從控(kong)(kong)(kong)制(zhi)模(mo)(mo)(mo)(mo)式(shi)(shi)(shi)下第一(yi)次進(jin)入窗(chuang)(chuang)(chuang)(chuang)口(kou)模(mo)(mo)(mo)(mo)式(shi)(shi)(shi),則(ze)會(hui)自動新建一(yi)個空白(bai)(bai)(bai)頁(ye)(ye)。其實(shi)注(zhu)(zhu)解(jie)模(mo)(mo)(mo)(mo)式(shi)(shi)(shi)可(ke)以理解(jie)為是(shi)窗(chuang)(chuang)(chuang)(chuang)口(kou)模(mo)(mo)(mo)(mo)式(shi)(shi)(shi)的(de)(de)(de)全屏(ping)顯示,在(zai)(zai)窗(chuang)(chuang)(chuang)(chuang)口(kou)模(mo)(mo)(mo)(mo)式(shi)(shi)(shi)中(zhong)能(neng)完(wan)成的(de)(de)(de)操作,在(zai)(zai)注(zhu)(zhu)解(jie)模(mo)(mo)(mo)(mo)式(shi)(shi)(shi)中(zhong)也(ye)能(neng)完(wan)成。
2、應用屏幕批注,增強課堂互動
用PPt或Flash等課件進行(xing)教學,填空、判斷題的答案和解題過程都是教師課前設置好的,不是師生互動產生的,這是對學生思維的越俎代庖。交互式電子白板能在各種課件、文本、圖片的畫面上進行無痕書寫涂畫。利用這一功能可以對白板呈現的重點內容進行批注,可以實時展現構建知識的過程,可以呈現師生互動交流的成果。這種環境下,知識在互動中生成,方法在互動中掌握,學生的主體意識在不斷增強。平時使用電子白板,多是在PPt畫面上寫寫畫畫,這便要求制作PPt時不能設置答案,要留足批注空間。應用方法是:控制模式下打開PPt課件的某張幻燈片,然后進入到注解模式下完成書寫、繪圖等操作。如要在下一張幻燈片上進行批注,須回到控制模式下再次播放幻燈片。
3、利用新建頁面,靈活展現板書
注解或窗口模式(shi)下(xia),新建的空(kong)白(bai)頁(ye)(ye)(ye)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)(mian)相(xiang)當于(yu)黑(hei)板,用電子(zi)筆可(ke)(ke)(ke)以進行自由地(di)(di)書寫,可(ke)(ke)(ke)以插入(ru)、編輯(ji)多媒體(ti)元素,也(ye)可(ke)(ke)(ke)以鏈接原始的圖片、音視頻文件。需(xu)(xu)(xu)要(yao)改變背(bei)景(jing)色(se),則要(yao)從格式(shi)菜(cai)單的“背(bei)景(jing)顏(yan)色(se)”中選擇需(xu)(xu)(xu)要(yao)的頁(ye)(ye)(ye)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)(mian)顏(yan)色(se)。如果默(mo)認頁(ye)(ye)(ye)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)(mian)不夠用時(shi),可(ke)(ke)(ke)在當前頁(ye)(ye)(ye)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)(mian)最下(xia)方點擊“擴(kuo)展頁(ye)(ye)(ye)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)(mian)”,當“擴(kuo)展頁(ye)(ye)(ye)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)(mian)”字(zi)體(ti)變灰時(shi)頁(ye)(ye)(ye)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)(mian)不再(zai)向下(xia)擴(kuo)展。這時(shi)還需(xu)(xu)(xu)要(yao)增(zeng)加板書,就(jiu)要(yao)點擊菜(cai)單上的“插入(ru)頁(ye)(ye)(ye)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)(mian)”再(zai)新建空(kong)白(bai)頁(ye)(ye)(ye)。電子(zi)白(bai)板會把使用過(guo)的頁(ye)(ye)(ye)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)(mian)內容自動記錄(lu)了下(xia)來,打(da)開頁(ye)(ye)(ye)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)(mian)預覽,可(ke)(ke)(ke)以看到所有使用過(guo)的頁(ye)(ye)(ye)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)(mian)。在頁(ye)(ye)(ye)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)(mian)預覽中可(ke)(ke)(ke)以拖動調整頁(ye)(ye)(ye)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)(mian)順序,可(ke)(ke)(ke)以更改頁(ye)(ye)(ye)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)(mian)標識,可(ke)(ke)(ke)以克隆、刪(shan)除頁(ye)(ye)(ye)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)(mian),教學(xue)時(shi)能(neng)方便地(di)(di)調用某張頁(ye)(ye)(ye)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)(mian)。根據需(xu)(xu)(xu)要(yao)也(ye)可(ke)(ke)(ke)以將頁(ye)(ye)(ye)面(mian)(mian)(mian)(mian)(mian)(mian)(mian)(mian)導出(chu)為圖片、網(wang)頁(ye)(ye)(ye)或資源。
4、巧用繪圖功能,強化圖形教學
電(dian)子白板(ban)提供的(de)(de)(de)幾何圖(tu)(tu)(tu)(tu)形(xing)(xing)(xing)、直(zhi)線、智能(neng)(neng)畫(hua)筆、三(san)角(jiao)尺、網格(ge)等工具(ju),可(ke)廣泛應(ying)用(yong)在空(kong)間與圖(tu)(tu)(tu)(tu)形(xing)(xing)(xing)領域(yu)的(de)(de)(de)教學(xue)(xue)中,它不(bu)但減少了(le)過去耗(hao)時(shi)耗(hao)力的(de)(de)(de)課前準備,還能(neng)(neng)使(shi)(shi)教學(xue)(xue)更(geng)加(jia)形(xing)(xing)(xing)象直(zhi)觀(guan)。如:教學(xue)(xue)《對稱(cheng)和平(ping)(ping)移(yi)》,首先在注解(jie)或全屏(ping)模式下(xia)新(xin)建空(kong)白頁(ye),設置并打開頁(ye)面網格(ge),然后(hou)用(yong)直(zhi)線工具(ju)畫(hua)一(yi)(yi)個(ge)(ge)圖(tu)(tu)(tu)(tu)形(xing)(xing)(xing),再將(jiang)線條(tiao)組合,當然也可(ke)以從幾何圖(tu)(tu)(tu)(tu)形(xing)(xing)(xing)中選擇(ze)(ze)一(yi)(yi)個(ge)(ge)圖(tu)(tu)(tu)(tu)形(xing)(xing)(xing)改變其(qi)形(xing)(xing)(xing)狀和大小。之后(hou)再克隆(long)出一(yi)(yi)個(ge)(ge)相同的(de)(de)(de)圖(tu)(tu)(tu)(tu)形(xing)(xing)(xing),接著就可(ke)以一(yi)(yi)格(ge)一(yi)(yi)格(ge)地拖動克隆(long)后(hou)的(de)(de)(de)圖(tu)(tu)(tu)(tu)形(xing)(xing)(xing),這樣(yang)學(xue)(xue)生(sheng)就清楚地觀(guan)察到了(le)圖(tu)(tu)(tu)(tu)形(xing)(xing)(xing)向什么(me)方向平(ping)(ping)移(yi)了(le)幾格(ge)。如需(xu)要展示軸對稱(cheng)圖(tu)(tu)(tu)(tu)形(xing)(xing)(xing),則可(ke)以把其(qi)中一(yi)(yi)個(ge)(ge)圖(tu)(tu)(tu)(tu)形(xing)(xing)(xing)進(jin)行水平(ping)(ping)翻轉。如果要刪除(chu)某個(ge)(ge)圖(tu)(tu)(tu)(tu)形(xing)(xing)(xing),橡皮擦(ca)無法使(shi)(shi)用(yong),需(xu)使(shi)(shi)用(yong)選擇(ze)(ze)對象工具(ju)選取圖(tu)(tu)(tu)(tu)形(xing)(xing)(xing)后(hou)進(jin)行刪除(chu)。教學(xue)(xue)中如能(neng)(neng)靈活應(ying)用(yong)電(dian)子白板(ban)的(de)(de)(de)各(ge)項功能(neng)(neng),可(ke)使(shi)(shi)空(kong)間與圖(tu)(tu)(tu)(tu)形(xing)(xing)(xing)的(de)(de)(de)教學(xue)(xue)更(geng)加(jia)形(xing)(xing)(xing)象化(hua)、清晰化(hua)。
5、采用工具作圖,提升課堂效率
日常教(jiao)學(xue)(xue)中,用(yong)三角(jiao)(jiao)(jiao)(jiao)(jiao)尺或(huo)量(liang)角(jiao)(jiao)(jiao)(jiao)(jiao)器在(zai)黑(hei)板上作(zuo)圖(tu),自(zi)己(ji)的(de)(de)身體(ti)往往遮住了(le)(le)(le)學(xue)(xue)生(sheng)的(de)(de)視線,學(xue)(xue)生(sheng)不能(neng)觀察到(dao)作(zuo)圖(tu)全過(guo)程(cheng)。電子白板提供(gong)了(le)(le)(le)圓規(gui)、三角(jiao)(jiao)(jiao)(jiao)(jiao)板、量(liang)角(jiao)(jiao)(jiao)(jiao)(jiao)器、直尺、智能(neng)畫(hua)筆等多種(zhong)工具,利(li)用(yong)這(zhe)些工具,教(jiao)師就(jiu)能(neng)在(zai)白板上輕松準確地畫(hua)出各類圖(tu)形(xing)。這(zhe)樣逼真的(de)(de)操(cao)作(zuo),增(zeng)強了(le)(le)(le)直觀感知,提升了(le)(le)(le)課堂效率。如(ru)(ru):教(jiao)學(xue)(xue)《畫(hua)角(jiao)(jiao)(jiao)(jiao)(jiao)》時,運用(yong)量(liang)角(jiao)(jiao)(jiao)(jiao)(jiao)器和(he)畫(hua)筆工具可以畫(hua)出任意度數的(de)(de)角(jiao)(jiao)(jiao)(jiao)(jiao),作(zuo)圖(tu)過(guo)程(cheng)學(xue)(xue)生(sheng)一(yi)目了(le)(le)(le)然(ran)。如(ru)(ru)要加深理解(jie),可以用(yong)頁面回(hui)放功(gong)能(neng)播放剛才畫(hua)角(jiao)(jiao)(jiao)(jiao)(jiao)的(de)(de)過(guo)程(cheng)。用(yong)兩個(ge)(ge)(ge)三角(jiao)(jiao)(jiao)(jiao)(jiao)板組合畫(hua)角(jiao)(jiao)(jiao)(jiao)(jiao)在(zai)黑(hei)板上演示較為(wei)困(kun)難,但在(zai)白板上完成(cheng)就(jiu)靈活自(zi)如(ru)(ru)了(le)(le)(le)。如(ru)(ru):畫(hua)一(yi)個(ge)(ge)(ge)75°的(de)(de)角(jiao)(jiao)(jiao)(jiao)(jiao),先從三角(jiao)(jiao)(jiao)(jiao)(jiao)板工具的(de)(de)功(gong)能(neng)菜(cai)單中選取(qu)45°的(de)(de)三角(jiao)(jiao)(jiao)(jiao)(jiao)板,之后再從功(gong)能(neng)菜(cai)單中選取(qu)30°的(de)(de)三角(jiao)(jiao)(jiao)(jiao)(jiao)板,這(zhe)時屏幕上出現了(le)(le)(le)兩個(ge)(ge)(ge)不同形(xing)狀的(de)(de)三角(jiao)(jiao)(jiao)(jiao)(jiao)板,通過(guo)拖(tuo)動旋轉,就(jiu)能(neng)組成(cheng)一(yi)個(ge)(ge)(ge)75°的(de)(de)角(jiao)(jiao)(jiao)(jiao)(jiao)。
6、運用相機功能,輕松裁剪圖片
制作課件時,我們常需要對一些圖片進行裁剪,利用Fireworks和Photoshop等軟件可以完成裁剪,但這對一些教師來說無疑是一個難題。電子白板的(de)(de)照相機(ji)功能,可以(yi)隨時完成對圖(tu)(tu)片(pian)(pian)的(de)(de)裁剪。比如要裁剪一張教材中(zhong)(zhong)的(de)(de)圖(tu)(tu)片(pian)(pian),先從電子教材中(zhong)(zhong)下載所需圖(tu)(tu)片(pian)(pian)并在(zai)控制模式下打(da)開,然后(hou)點擊照相機(ji)區(qu)域快照按鈕,拖(tuo)動光標選(xuan)擇需要裁剪的(de)(de)區(qu)域,再次點擊光標后(hou)區(qu)域中(zhong)(zhong)的(de)(de)照片(pian)(pian)就自動粘貼到了空白頁(ye)或(huo)(huo)最后(hou)使用(yong)(yong)過的(de)(de)頁(ye)面(mian)上。這時可以(yi)對裁剪后(hou)的(de)(de)圖(tu)(tu)片(pian)(pian)進(jin)行(xing)移動、放大或(huo)(huo)縮(suo)小等操作,當(dang)然也可將(jiang)裁剪后(hou)的(de)(de)圖(tu)(tu)片(pian)(pian)添加到圖(tu)(tu)庫或(huo)(huo)復制到其它程序使用(yong)(yong)。運用(yong)(yong)相機(ji)功能,我們(men)也可以(yi)將(jiang)網頁(ye)、Word文檔或(huo)(huo)課件上的(de)(de)有用(yong)(yong)內容(rong)進(jin)行(xing)裁剪使用(yong)(yong)。
