课件制作工具：Authorware7.0 、photoshop9.0、Flash MX、绘声绘影8.0等
课件使用环境：
软件环境：安装windows2000、windowsxp或vista操作系统。
硬件环境：需要Celeron 400以上中央处理器、显卡、声卡、音响等。
制作思想：初中化学教学活动应该以学生为主体，激发学生学习兴趣，开阔视野，定性粗略研究化学现象，而要达到这一最低目标也并非易事，比如我们常因为班级人数过多，教师演示实验仪器太少，只能满足少部分人的学习要求，大部分人只能似是而非，一知半解，甚至根本看不到实验，听不着课。虽然以往说《氧气的获得》一节应重视实验操作，不宜多媒体演示，但事实证明只实验不能满足学生需要。本课件恰好能辅助正常课堂实验教学，对于难点和学生不易观察到的实验现象可反复演示，直到弄懂为止。“挑战擂台”部分还设有题库，可反复随机出5道题检验学生对已理解知识的掌握情况，并能实现自动评分，教师能得到较全面的信息反馈。“课堂小结”部分按照知识结构概述本课知识要点，使学生能记住知识的脉络框架和要点。最后的“资料链接”作为教师备课参考资料，也可以作为新课改教学课堂活动的素材，教师可出一关键词，让学生到网络上搜索，学生在参与搜索的过程中能产生向知性和学习的主动性。
教学内容说明
教学目标：
1.使学生掌握实验室制取氧气的方法和反应原理，了解工业制取氧气的基本方法和原理
2.知道实验室可用过氧化氢、高锰酸钾制取氧气及反应的原理、装置、检验、验满方法等
3.初步理解分解反应，了解催化剂和催化作用
实验用品
试管、带导管的橡皮塞、集气瓶、毛玻璃片、水槽、酒精灯、火柴、木条、铁架台（带铁夹）、试管夹、分液漏斗、药匙、高锰酸钾、过氧化氢、二氧化锰等。
教学过程及分析
创设问题情境——上一讲我们学了氧气那么多的用途， 那么些我们如何得到氧气呢？如何把氧气收集到这个集气瓶中呢？教师举起一个集气瓶向学生展示，这样开门见山把学生思维一下子拉到本课题中来。通过学生分组实验探究，观察现象，讨论对比，引入催化剂、实验室氧气制取的一般思路和分解反应的结论，一环扣一环，逐渐深入，从而达到本课是的教学目标。
互动交流——教师是学习的引导者，学生是学习的主体。大家都知道交流是教学和学习一种有效方式，是一种多项信息互通的活动，是在教师指导下通过问题引发学生查阅资料、提出假设、验证假设的过程，通过师生之间、生生之间为了某一共同目的而进行的沟通、对答、对话、理解的过程，从而解决问题的探究式学习活动。通过多媒体教学手段，让教与学的交流、互动，师生双方相互沟通、相互启发、相互补充，交流彼此的情感、体验与观念，丰富教学内容，求得新的发现，从而达到共识、共享、共进，实现教学相长和共同发展。
实验探究——探究是学习的一条重要途径，通过实验探究双氧水分解产生氧气的现象，引导学生去观察、分析、对比、讨论，师生之间、生生之间互动交流引导出催化剂概念，并选择实验方案进行实验，体验到制取氧气成功的喜悦。
总结反思——教学反思，是教师对自己已完成的教学实践活动有目的地进行审视，做出理性思考，并用以指导日后的教学。学完本节课后，教师和学生一起总结和反思。一方面，反思教材实验编排、实验药品、实验装置、实验步骤、操作过程、实验现象及实验失败或过失的原因。如：用燃着的木条伸入盛有双氧水和二氧化锰的试管中，木条也可能出现不复燃的情况；实验后二氧化锰质量没有改变，课本仅仅用一句话说明，课堂上可添加实验或将课堂实验延伸到课外让学生实验来说明；实验中氧气是否由二氧化锰放出等都值得进一步探究与实验。另一方面，教师依据整节课的环节，结合教材对全课及探究过程进行总结。
本节课的特点是理论学习与实践体验结合和基本操作与具体实验结合，我们采用多媒体辅助，问题教学、实验探究的方法。本节课内容较多，建议分两课时完成。XtrAgent Trial Version 2.0

2002.6FileIO Xtra for Macromedia Authorware 7.0
Copyright 2003 Macromedia, Inc.
FileIO provides a set of functions allowing users of Macromedia Authorware to programmatically access files using scripting.
Using FileIO
============
As an Xtra the FileIO Xtra must be in your application's Xtras folder.
Each instance of FileIO can reference a single open file. If multiple files are to be opened simultaneously, a new instance of FileIO is required for each opened file. A single instance can be used to open multiple files, as long as the file is closed before a new file is opened. To create a new instance use NewObject, defined below. To dispose of an instance, set the instance variable to 0. All functions that read from or write to the file must be called after the file has been opened using openFile. If a new file is to be opened using the same instance, the old file must first be closed using closeFile. Files can be opened in three different modes: Read, Write and Read/Write. When writing to a file, the contents of the file after the current position are overwritten.
Example Script:
-- Create an instance of FileIO
myFile := NewObject("fileio")
-- Display an "open" dialog and return the file name to Authorware
myFileName := CallObject(myFile, "displayOpen")
-- Open the file
CallObject(myFile, "openFile", myFileName, 1)
-- Read the file and return a string to Authorware
theFile := CallObject(myFile, "readFile")
-- Close the file
CallObject(myFile, "closeFile")
-- Dispose of the instance
myFile := 0
In this example, a new instance was created and stored in the variable myFile. Next, a call to displayOpen is used to display an open dialog to allow a file to be selected. The file name is returned as a fully qualified path string to Authorware. The file is then opened in read-only mode, the contents of the file are read, and the file is closed. Lastly, the instance is disposed.
There is also an Authorware Show Me (xtraio.a7p) which demonstrates how to use the Xtra. It can be found in the Show Mes installed with Authorware.
Known Problems
==============
The FileIO Xtra cannot use a net-based file when supplied with a URL for the file name. It is limited to accessing files available via file systems mounted on the local system.
Function Reference
==================
closeFile
CallObject(object, "closeFile")
Closes a file that has been previously opened using openFile.
createFile
CallObject(object, "createFile", "fileName")
Creates a file. The fileName must be either a fileName to be created in the current directory, or a fully qualified path and fileName. Relative paths are not supported. After creating the new file, the file must be opened before it can be written to.
delete
CallObject(object, "delete")
Deletes the currently opened file. The file must be open to use this function.
displayOpen
CallObject(object, "displayOpen")
Displays a platform specific "open" dialog allowing a user to select a file. Returns a fully qualified path and fileName to Authorware. The setFilterMask function can be used to control what file types are displayed in the dialog.
displaySave
CallObject(object, "displaySave", "title", "defaultFileName")
Displays a platform specific "save" dialog allowing a user to specify a file. Returns a fully qualified path and fileName to Authorware. The setFilterMask function can be used to control what file types are displayed in the dialog. The title and defaultFileName parameters allow you to specify a default filename to be displayed, as well as title text for the save dialog.
error
CallObject(object, "error", status)
Returns a readable error string. A numeric error code is passed in as the third argument. (Also refer to the 'status' function.) The errors returned can be any of the following:
"OK"
"Memory allocation failure"
"File directory full"
"Volume full"
"Volume not found"
"I/O Error"
"Bad file name"
"File not open"
"Too many files open"
"File not found"
"No such drive"
"No disk in drive"
"Directory not found"
"Instance has an open file"
"File already exists"
"File is opened read-only"
"File is opened write-only"
"Unknown error"
fileName
CallObject(object, "fileName")
Returns the file name string of the current open file. The file must be open use this function.
getFinderInfo
CallObject(object, "getFinderInfo")
Returns the Type and Creator of the current file as a string. This function does nothing when used under Windows. The file must be open to use this function.
getLength
CallObject(object, "getLength")
Gets the length of the currently opened file. Returned as an integer. The file must be open to use this function. The value returned is the length of the file in bytes.
getOSDirectory
getOSDirectory()
A function that returns the full path to either the Windows directory, or the System Folder depending on which OS is currently being used. Does not require a child instance to call.
getPosition
CallObject(object, "getPosition")
Gets the file position of the current open file. Returned as an integer. The file must be open to use this function.
NewObject
NewObject("fileio")
This is called to create a new instance of FileIO. It returns an instance variable used to reference the instance.
openFile
CallObject(object, "openFile", "fileName", mode)
Opens the named file. This call must be used before any read/write operations can take place. The filename can be either a fully qualified path and filename, or a relative filename. The openMode parameter specifies whether to open the file in Read, Write or Read Write mode. Valid Flags are: 0 Read/Write, 1 Read, 2 Write.
readChar
CallObject(object, "readChar")
Reads the character (either single or double-byte) at the current position and then increments the position. The character is returned to Authorware as a string. The file must be open in read or read/write mode to use this function.
readFile
CallObject(object, "readFile")
Reads from the current position to the end of the file and returns the file to Authorware as a string. The file must be open in read or read/write mode to use this function.
readLine
CallObject(object, "readLine")
Reads from the current position up to and including the next Return, increments the position, and returns the string to Authorware. The file must be open in read or read/write mode to use this function.
readToken
CallObject(object, "readToken", "skip", "break")
Reads the next 'token' starting at the current position. Characters matching the 'skip' parameter are "skipped" and the file is read until 'break' is encountered. The file must be open in read or read/write mode to use this function. This function will read double-byte tokens as long as the skip and break are single-byte characters. It will not detect double-byte skip or break characters.
readWord
CallObject(object, "readWord")
Reads the next word starting at the current position. The file must be open in read or read/write mode to use this function.
setFilterMask
Sets the filter mask used by calls to displayOpen and displaySave. The filter mask determines what files to show when displaying an "open" or "save" dialog. The third parameter is a string representing the filter mask to set.
On Windows, this is a comma-separated string of file types and associated extensions (e.g. "All Files,*.*,Text Files,*.TXT"), and a string of types on the Macintosh (e.g. "TEXTPICT"). On Windows, the filter mask string is limited to 256 characters.
If a file type has more than one associated extension, separate the extensions with a semi-colon, rather than a comma (e.g. "All Available Sound,*.WAV;*.MP3;*.SWA;*.VOX").
On the Macintosh, you are limited to four four-character types.
When a new instance of FileIO is created, the filter masks defaults to all files. To reset the filter mask to display all files after it has been set, just pass in an empty string, e.g. CallObject(object, "setFilterMask", "").
setFinderInfo
CallObject(object, "setFinderInfo", "attributes")
Sets the Type and Creator of the current file. The string takes the form of a space-separated set of TYPE and CREATOR codes (e.g. "TEXT TTXT"). This function does nothing when used under Windows. The file must be open to use this function.
setPosition
CallObject(object, "setPosition", position)
Sets the file position of the current open file. The file must be open to use this function.
status
CallObject(object, "status")
Returns the error code returned by the last function called. The value is returned as an integer. (Also refer to the 'error' function.)
version
CallParentObject("fileio", "version")
Returns FileIO version and build information. Useful when filing bug reports, or determining installed version while authoring. No practical use beyond this.
writeChar
CallObject(object, "writeChar", "theChar")
Writes a single character to the file at the current position. The file must be open in write or read/write mode to use this function.
writeString
CallObject(object, "writeString", "theString")
Writes a string to the file at the current position. The file must be open in write or read/write mode to use this function.
