as shown in fig1 , an interactive computer system for instructor - student teaching and assessment of preschool children in accordance with one embodiment of the invention is employed in a computer network having a plurality of computer stations 30 along with a server station 32 interconnected by a network 34 . each computer station 30 typically includes a central processing unit 36 which is connected to a keyboard 38 , a mouse 40 , a monitor 46 , a speaker 42 and a printer 44 . the central unit 36 typically includes a read / write removable media device such as floppy disk drive 46 , a read only removable media device such as a cd - rom or dvd reader ( or reader / writer ) 48 and a mass storage device such as a hard drive 50 . the server station 32 is similar to the computer stations but has a server unit 52 which contains storage units for holding a large quantity of files which are accessed by the computer stations 30 through the network 34 . the network 34 in one preferred embodiment is the world wide web ( sometimes called the internet ) but could alternatively be one of a variety of other possible network configurations . where the educational management system is employed in a single school or closely distanced schools , the network 34 can be a hardwired internal network or connected through dedicated lines ( sometimes called an intranet ). the interactive computer system for instructor - student teaching and assessment of preschool children is formed by one or more software programs which control and operate the computers 30 and server 32 . in the program shown in fig2 , the user enters a user name and password to gain access to the program . next the window of fig3 is displayed with options “ curriculum resources ” 64 , “ assessment ” 66 and “ instruction ” 68 for the user to select . in step 70 if the user selects “ curriculum resources ” the program calls a curriculum resources procedure 72 in which the user can retrieve documents , background information , support information , and other information about the invention . if assessment 66 is selected , step 74 branches to the assessment procedure 76 of fig4 , 7 and 11 and if instruction 68 is selected , step 78 branches to the instruction procedure 80 of fig1 . in the assessment procedure 76 , the window 84 , fig5 , is initially displayed to instruct the teacher that no feedback regarding right or wrong answers should be given to the student during the assessment procedure . next the window 86 , fig6 , is displayed . this window 86 contains a scale selection window 88 , a knowledge area selection window 90 and a window 92 listing the animated activities , descriptions of the corresponding activities and the goals to be achieved by the corresponding activities along with check boxes 94 by which the user can select a particular animated activity of assessment . after the user has selected the scale to be assessed in step 100 it is determined if the user has elected to assess a single knowledge area in step 102 . selection of a single knowledge area in step 104 reduces the number of activities displayed in window 92 to those activities relating to the selected single knowledge area instead of a listing of all activities relating to the selected scale . in step 106 , the user clicks on one of the check boxes 94 to select an animated activity for child assessment . clicking on the next button 108 in fig6 calls the next procedure 110 in fig7 . in the second portion of the assessment procedure 110 of fig7 , the window 112 of fig8 is displayed . this window contains a class selection window 114 and a child selection window 116 . the user in step 118 uses the window 114 to select a class containing the child to be assessed and in step 120 uses the window 116 to select the child to be assessed . after selection of the child , step 122 displays a list 124 of the goals of the selected activity and the achievement status of these goals by the selected child . then clicking on the start button 128 calls the third portion ( start ) 130 , fig9 , of the assessment procedure . the selected animation activity is downloaded , if on the internet , and an initial screen ( not shown ) with another start activity button ( not shown ). then in step 132 the procedure determines if the user has clicked on the start activity button and , if true , proceeds to step 134 where the activity is played . playing the activity results in animated display of a cartoon in the upper portion of the display which contains a plurality of components which are readily recognizable by a preschool age child . for example the screens of fig1 - 15 contain scenes from separate animated acts in an activity call “ guess the action ” containing components including cartoon characters 140 ( argus the alligator ) and 142 ( belle the bunny ), play items such as balls 144 and 146 , other items such as square 148 , pizza 150 , glass of ice 152 , red shirt 154 , blue shirt 156 , desk 158 and bunk bed 160 . in step 162 the instructor guides the child in the activity . on the lower portion of the screen a written instruction 164 is displayed for providing instruction and guidance to the instructor while monitoring or helping the child . during play of each act , the vocal story requests selection of one of the displayed components which have a predefined aspect related to a goal being assessed . for example in the scene of fig1 , selection of the character standing on something square is requested . the program activates screen regions on the characters as buttons which can be clicked or alternatively touched in the case a touch screen is used and waits until a selection is made . use of the mouse 40 to move the pointer 166 and clicking on the character standing on the square 148 by the child or by the instructor in response to the child pointing to the character indicates that the child has achieved an understanding of the word “ square ”. in the scenes of fig1 - 15 the understanding of other words or aspects are assessed ; in fig1 - - - “ hot ”, in fig1 , - - - “ blue ”, in fig1 - - - “ next to ”, in fig1 - - - “ behind ”, and in fig1 - - - “ bottom ”. following the play and completion of selections in the scenes of the activity , step 170 displays the window 172 in fig1 which displays the results of the assessment activity just played . correct selection of the displayed components having the requested predefined aspects in the scenes of fig1 - 15 results in the indication that the goals of the activity have been achieved , i . e . “ learned ”. incorrect selection of one or more components results in an indication that one or more goals of the activity have not been achieved i . e ., “ not learned ”. the combination of the display of an assessment activity by the computer on a first portion of the screen in a format such as a cartoon which is attractive to preschool children with the display of written instructions for the teacher on a second portion of the screen provides for the unique interaction between a child and the teacher resulting in improved learning by the child . the child is readily instructed in the use of the mouse and can independently perform the activity after learning its use . the teacher by reading the written instructions is assisted in providing guidance , such as repeating a request , to a child . referring back to fig9 , step 174 permits the instructor to request repeating the assessment activity , steps 134 , 162 and 170 so that multiple children can be assessed using the same assessment activity . step 176 responds to clicking on an exit button ( not shown ) to return the program to the procedure of fig7 . when the instruction button 68 of fig3 is selected , the procedure of fig1 is called and the window 180 of fig1 is displayed . in step 182 , a scale and a knowledge area are selected using the scale select window 184 and the knowledge area select window 186 which results in the display of a listing 188 of the instruction activities relating to the selected scale and knowledge area . step 190 provides to the selection of a print name tag button 192 calling a name tag printing procedure 194 . an instruction activity is selected from the list 188 in the step 196 by clicking on a check box 198 associated with the selected activity . similar to the assessment activities , the animated cartoon of the instruction activity is accessed or downloaded if on the internet and an initial screen with a start or play button is displayed . clicking on the start button , step 200 , plays the cartoon . the instruction activity can have interactive portions similar to assessment activities or can be simply instructive . instructional activities can be played individually or by a class or group of children . guidance for the instructor can also be displayed on the screen , step 202 , in promoting interaction with a child or children . scenes of fig1 and 20 illustrate an instructional activity relates to the use of letters to form words . in the first scene of fig1 the vocal story describes the magician argus magically displaying the word “ cap ” on the front side of a box . sliding the front side upward shows a cap inside the box . the story requests that each letter , successively highlighted , be clicked on by a child or instructor , whereupon the phonetic sound of the letter is broadcast on the speaker . then in the second scene of fig2 the story tells of argus magically changing the letter “ c ” to “ m ”. again the story requests clicking on each letter of the new word and broadcasts the phonetic sounds of each letter followed by raising the front side and display of a map inside the box . a screen 204 of another instruction activity shows the upper portion 206 where a cartoon shows a plate with letters to be selected by the child to form a word or name . a lower portion 208 of the screen contains written instructions for the instructor in promoting learning and interaction with the child . step 210 in fig1 illustrates that the user can click on the close button in any window to close that window . the above description of detailed description of the invention and the accompanying drawings are only illustrative of one embodiment of the invention and only illustrate a small portion of an extensive library of assessment activities and instruction activities . many modifications , changes in detail and variations can be devised without departing from the scope and spirit of the invention . it will be obvious to those having skill in the art that many changes may be made to the details of the above -
