On the effect of using PPT to finish the blackboard writing

In Flash, through a lot of layers, frames and statements in the courseware table to achieve the effect of writing on the blackboard (that is, the contents of the other cells will not disappear when filling a box). This is difficult for teachers who are unfamiliar with flash software. In fact, this effect can be easily achieved with PowerPoint, not so many layers do not need to write any statements, even the computer level of the general teachers, as long as the master of this method, whether it is three columns four rows or six columns of eight rows of the table, as long as a slide, five minutes can be easily handled, to know how the details, Come with me, please.

2. Insert a text box in each pane of the table, enter text (Note: You cannot enter text directly in the table), and adjust the text size and color.

3. Set the animation of each text box with a custom animation (right-click or slide Show menu).

4. Draw a rectangle with a PowerPoint drawing tool that is equal to the size or slightly smaller of each cell in the table, the line (that is, the border) color is defined as "none", and what color is filled but must not be defined as "none", otherwise it cannot be used. Then click the right button to select "Format AutoShape" in the right menu, set the transparency of the fill to 100% (that is, full transparency), and to make it easier to see when you're done, you can set it to full transparency.

5. Copy the Painted rectangles (by the number of cells) and overlay them on each cell, where you remember the order of the copied rectangles for the following actions.

Open Custom Animation, select the text box you want to manipulate from the list of animations, click on the small triangle appearing on the right, select the Timer/trigger/Click Start effect from the menu that appears, and select the rectangle that is overlaid on the text in the small window that appears on the right ( It is automatically numbered in the order in which it is copied, which is why you should remember the order of replication, and then you can try it after clicking the (OK) button. Each of the other cells and so forth. If there is not a corresponding (that is, click on the cell will appear in another cell text), as long as the cell in the rectangle to swap.
