METHOD OF PREDICTIVE ASSESSMENT

RELATED APPLICATIONS The present non-provisional patent application claims priority benefit with regard to all common subject matter of an earlier-filed copending provisional patent application titled EDUCATIONAL METHOD, SOFTWARE, AND SYSTEM, Serial No. 60/510,692, filed October 10, 2003 and of an earlier-filed copending provisional patent application titled EDUCATIONAL METHOD, SOFTWARE, AND SYSTEM, Serial No. 60/513,875, filed October 22, 2003. The identified provisional patent application is hereby incorporated by reference into the present non- provisional patent application.

BACKGROUND OF THE INVENTION 1. FIELD OF THE INVENTION The present invention relates broadly to methods and techniques for teaching and testing. More specifically, the present invention concerns a method of predictive assessment that merges learning and testing by teaching through repeated assessment in order to instill in a user an intuitive understanding of a concept or conceptual relationship. The method makes use of an Educational Object that is abstracted from an epistemic model. Broadly, a user adjusts a characteristic of a Trial Object in an attempt to match the characteristic with that of a Target Object. An Evaluation Function determines the results of and updates the Trial Object to reflect the user's adjustments, and an Assessment Metric compiles data on the user's attempts to achieve a match. 2. DESCRIPTION OF THE PRIOR ART It is often desirable or necessary to reliably teach or test understanding of a concept or conceptual relationship from an epistemic body of knowledge. Currently, however, there are no standardized mechanisms ortechniques in the field of education for assessing such knowledge. Instead, an ad hoc system of testing is used that typically involves a plurality of multiple choice questions that test recognition and recollection rather than true understanding and mastery of the knowledge. Even the most sophisticated of these prior art testing techniques involves little more than regurgitation of memorized material. Furthermore, students or other test-takers have traditionally devised ways to make it appear to instructors or other evaluators that they understand concepts, even when they do not. Due to these and other problems and disadvantages in the prior art, a need exists for an improved method of teaching and testing.

SUMMARY OF THE INVENTION The present invention overcomes the above-described and other problems and disadvantages in the prior art by providing a method of predictive assessment that merges learning and testing by teaching through repeated assessment. The method instills in a user an intuitive understanding, and provides assessment records that allow an evaluator to easily determine whether the user is actually learning and, if not, how best to provide individualized assistance to the user in order to achieve learning and mastery of the subject. The method makes use of an Educational Object, which is an assessment and learning tool that models a concept or a simple or complex conceptual relationship present within an epistemic model. The Educational Object broadly comprises a Target Object; one or more Target Controls; a Trial Object; one or more Trial Controls; an Evaluation Function; and an Assessment Metric. The Target Object represents a result or other goal that the user must achieve by developing an understanding of the underlying concept or conceptual relationship. The Target Controls allow the evaluatorto initially configure the characteristics of the Target Object. The Trial Object is the user's vehicle for conducting predictive experimentation in order to learn and demonstrate knowledge of the concept or conceptual relationship by adjusting the characteristics of the Trial Object to match those of the Target Object. The Trial Controls allow the user to make these adjustments to the characteristics of the Trial Object. The Evaluation Function receives and evaluates the adjustments to determine whether a successful match has been achieved. The Evaluation Function also updates or changes the Trial Object to reflect the adjustments so that the user can see the effects of the adjustments. If the result is not a match, then another adjustment is called for, with the user's next adjustment being applied to the previously adjusted Trial Object. The Assessment Metric is a record of the user's performance in attempting to match the Target and Trial Objects. The Assessment Metric may include such data as, for example, the number of attempts required by the user to achieve a match, the elapsed time, and the particular adjustments or pattern of adjustments employed by the user. In use and operation, the characteristics of the Target Object are first configured, the user is presented with the Target Object, and the predictive assessment process begins. The user is allowed to make an adjustment to the Trial Controls in an attempt to match the characteristics of the Trial Object with those of the Target Object. Once the user indicates he or she is finished with an adjustment, the result of the adjustment is revealed by changing or otherwise updating the Trial Object to reflect the adjustment. If the result is not a match, then the user is allowed to make another adjustment. This next adjustment is facilitated by the user visually or otherwise comparing the adjusted Trial Object with the Target Object, and taking note of the effect of the previous adjustment. During this process of adjustment and readjustment, assessment data of the user's attempts to match the Target and Trial Objects is compiled. After one or more iterations of this process of adjustment, assessment, and readjustment, the user should begin to develop an intuitive understanding of the concept or conceptual relationship involved and be able to predict the results of further adjustments to achieve a match with the Target Object. When the user can match the Trial Object to the Target Object within a pre-established acceptable amount of time and using no more than a pre-established maximum number of adjustments, then the user is considered to understand and be proficient in the task. Educational Objects can be authored or created to model a variety of concepts or conceptual relationships. Possibilities include, for example, teaching Ohm's Law and wire gauge selection wherein the user develops an intuitive understanding of Ohm's Law and uses this knowledge to make appropriate wire gauge selections; teaching a process of color matching wherein the user adjusts color components of the Trial Object until its color matches the color of the Target Object; or teaching a process of spatial or geometric recognition wherein the user adjusts side, length, and angle components of the Trial Object until its shape matches the shape of the Target Object. Thus, it will be appreciated that the present invention provides a number of substantial advantages over the prior art, including, for example, merging learning and assessment to provide dramatically improved understanding of essential concepts. Testing has shown that the method of the present invention allows users to learn essential concepts in approximately one quarter of the time required by traditional teaching techniques. Furthermore, the method of the present invention also advantageously provides a standardized mechanism for evaluating user understanding or performance; allows for criterion referenced assessment using multiple configurations of the Educational Object; and allows for team predictive performance assessment. These and other important features of the present invention are more fully described in the section titled DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT, below.

BRIEF DESCRIPTION OF THE DRAWINGS A preferred embodiment of the present invention is described in detail below with reference to the attached drawing figures, wherein: FIG. 1 is a high-level representation of a process of creating an Educational Object based upon an epistemic model, wherein the Educational Object is a primary component in the method of the present invention; FIG. 2 is a block diagram showing components of a preferred embodiment of the Educational Object of the present invention; FIG. 3 is a flowchart of steps involved in practicing a preferred embodiment of the method of the present invention; FIG. 4 is a block diagram showing certain components of the Educational

Object adapted for team predictive performance assessment; and FIG. 5 is a depiction of a user interface associated with an exemplary and illustrative Educational Object specifically adapted for teaching or testing concepts and conceptual relationships related to Ohm's Law and wire gauge selection.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT With reference to the figures, a method of predictive assessment is described, shown, and otherwise disclosed in accordance with a preferred embodiment of the present invention. Broadly, the method merges learning and testing by teaching through repeated assessment. Because the method may be used to merely teach, teach and test, or merely test, as used herein "evaluator" should be understood to refer to any person or entity (e.g., teacher, instructor, supervisor, proctor) with control over the process of predictive assessment, while "user" should be understood to refer to any person or entity (e.g., student, test-taker, candidate) undergoing the process of predictive assessment. In that light, the method provides a technique for instilling within the user an intuitive understanding, and provides assessment records that allow the evaluator to easily determine whether the user is actually learning and, if not, how best to provide individualized assistance to the user in order to achieve learning and mastery of the subject. Referring particularly to FIGs. 1 and 2, the method makes use of an Educational Object 10 which is an assessment and learning tool that models a concept or a simple or complex conceptual relationship present within an epistemic model 12. Such a conceptual relationship typically involves a concept, value, or function that is either modified by or that modifies another concept, value, or function. Because the Educational Object 10 is an abstraction of the epistemic model 12, it allows for assessing both the user's understanding of the concept or conceptual relationship and the user's cognitive processes in learning the concept or conceptual relationship. Thus, both the user's grasp of the information and their ability to "figure out how it works" are assessed. Furthermore, because epistemic models 12 are universally accepted, performance can be consistently measured, and the Educational Object 10 establishes standardized assessment criteria. The method is preferably implemented in a computer program written in REBOL (Relative Expression-Based Object Language). Alternatively, any suitable or otherwise desirable programming language may be used. REBOL, however, was designed specifically for distributed Internet applications and data exchange across all platforms. REBOL/IOS provides an X-lnternet ("executable Internet") framework that allows the Educational Object 10 to be distributed easily across networks and into classrooms or organizations or used as a platform for distance learning. REBOL/IOS X-lnternet software provides several advantages over other platforms, including, for example, that the Education Object 10 can be written as a tiny application called a "reblet", distributed instantly, and connected for real-time interaction between multiple users. Furthermore, X-lnternettechnology ensures that even when widely-distributed the Educational Object 10 is responsive and secure, 5 and that only properly authenticated users are able to access a closed group. In that light, the method of the present invention may be implemented in a variety of ways and scales. For example, the method may be implemented for use in a traditional classroom environment, or to facilitate distance learning across a wide area network (WAN) such has the Internet. Thus, the present invention could

10 be adopted as a mechanism for both teaching and certifying professionals or tradesmen, such as electricians. The Educational Object 10 broadly comprises a Target Object 16; one or more Target Controls 18; a Trial Object 20; one or more Trial Controls 22; an Evaluation Function 24; and an Assessment Metric 26. The Target Object 16

15 represents a result or other goal that the user must achieve by developing an understanding of the underlying concept or conceptual relationship. The Target Controls 18 allow the evaluator to initially configure the characteristics of the Target Object 16. Alternatively, these characteristics can be randomly generated, requiring no action by the evaluator. The Trial Object 20 is the user's vehicle for conducting

20 predictive experimentation in order to learn and demonstrate knowledge of the concept or conceptual relationship by adjusting the characteristics of the Trial Object 20 to match those of the Target Object 16. The Trial Controls 22 allow the user to make these adjustments to the Trial Object 20. Thus, the nature of the Trial Controls 22 will depend upon the nature of the Educational Object and of the concept or

25 conceptual relationship involved, but may include, for example, any number or combination of real or virtual switches, buttons, sliding switches, or data input fields. The Evaluation Function 24 receives and evaluates the adjustments made by the user to determine whether a successful match has been achieved. The Evaluation Function 24 also updates or changes the Trial Object

30 20 to reflect the adjustments so that the user can see the effects the adjustments. If the result is not a match, then another adjustment is called for, with the user's next adjustment being applied to the previously adjusted Trial Object 20. The Assessment Metric 26 is a record of the user's performance in attempting to match the Target and Trial Objects 16,20. The Assessment Metric 26 may include such data as, for example, the number of attempts required by the user to achieve a match, the elapsed time, and the particular adjustments or pattern of adjustments employed by the user (e.g., high, low, high, low, match, or high, high, high, high, match). This data can be presented in text or graph form, as desired, and can be used to determine additional useful information, including, for example, the cognitive processes employed by the user during the process. Referring also to FIG. 3, in use and operation the method proceeds broadly as follows. The characteristics of the Target Object are first configured, either by the evaluator using the Target Controls or automatically, as depicted in box 100. If manually configured, the Target and Trial Objects 16,20 are communicated from the evaluator's computer to the user's computer via X-lnternet delivery using file-set synchronization and messaging. The user is then presented with the Target Object 16 and the predictive assessment process begins. The user is allowed to make an adjustment to the Trial Controls 22 in an attempt to match the characteristics of the Trial Object 20 with those of the Target Object 16, as depicted in box 102. Once the user indicates he or she is finished with an adjustment, as depicted in box 104, the result of the adjustment is revealed by changing or otherwise updating the Trial Object 20 to reflect the adjustment, as depicted in box 106. If the result is not a match, then the user is allowed to make another adjustment, as depicted in box 108. The result of the previous adjustment remains presented, and this next adjustment is applied to the previously adjusted Trial Object 20 and not to the Trial Object 20 as it was initially generated. The next adjustment is facilitated by the user visually or otherwise comparing the adjusted Trial Object 20 with the Target Object 16 and taking into consideration the effects of the previous adjustment. During this process of adjustment and readjustment, assessment data of the user's attempts to match the Target and Trial Objects 16,20 is compiled, as depicted in box 110. After one or more iterations of this process of adjustment, assessment, and readjustment, the user should begin to develop an intuitive understanding of the concept or conceptual relationship involved and be able to predict the results of further adjustments to achieve a match with the Target Object 16. When the user can match the Trial Object 20 to the Target Object 16 within a pre-established acceptable amount of time and using no more than a pre-established maximum number of adjustments, then the user is considered to understand and be proficient in the task. As desired, the user may be provided with any appropriate real or virtual tools or resources necessary to achieve or assist in achieving the match. These tools might include, for example, calculators, templates, protractors, and graphing tools. The user's use of these tools is preferably recorded and incorporated into the assessment statistics and other data so that the evaluator can later review such use in order to determine where any mistakes may have occurred. It will be appreciated that the method of the present invention advantageously allows for criterion referenced assessment. Criterion referenced assessment requires that specific outcomes be met by a large population of test- takers using multiple assessment instruments. The criterion exists external to the assessments that reference it. More specifically, commonly accepted epistemic models establish the criterion that the Educational Objects 10 reference. Multiple configurations of the Educational Object 10 meet the multiple assessment requirement. The same Educational Object 10 can be used by many users, thereby creating a criterion referenced assessment. Referring to FIG.4, it will also be appreciated that the present invention allows for team predictive performance assessment. Predictive performance assessment for teams involves multiple users working to achieve a single objective or multiple related objectives. More specifically, the method can be used to test teams by linking multiple users to the same Educational Object 10, multiple instances of the same Educational Object 10 in different configurations, or multiple Educational Objects 10 that affect each other. Delta Functions 28 placed between the Trial Controls 22 and the Trial Object 20 allow attributes of the Trial Object 20 to be controlled by multiple users. The evaluator controls the number of users, the number and configuration of Target Objects 16, and the Assessment Metrics 26 to be displayed and collected. The Delta Functions 28 permit team assessment by allowing the Trial Controls 22 of any similar Educational Object 10 to control the attributes of another or of several other Educational Objects 10. Target and Trial Objects 16,20 can be configured to control other objects through these Delta Functions 28, creating one-to- many, many-to-one, and many-to-many relationships. Any X-lnternet or other convenient method of linking Trial Controls 22 to the Delta Functions 28 can be employed. Assessment data can be collected for individual team members as well as for the aggregate team. Thus, any configuration of identical, similar, or different Educational Objects 10 can be related through the Delta Functions 28, thereby establishing a platform for standardized team assessment. As mentioned, the method of the present invention allows for online delivery of education through X-lnternet distribution of the Educational Objects 10. The X-lnternet consists of executable code distributed across networks and digital constructs passed across networks between applications providing functional peer- to-peer real-time interactivity. Educational Objects 10, when distributed through X- Internet systems, create a medium of communication between evaluators and users. The aforementioned Delta Functions 28 allow multiple users to control the same Target and Trial Objects 16,20. The resulting changes allow for responses and communication is established which constitutes online delivery of education. The method of the present invention is adaptable to teach or test a wide variety of different concepts or conceptual relationships. Referring also to FIG. 5, what follows is a non-limiting description of an exemplary and illustrative application of the method to teach and test electrical knowledge. It is necessary for practitioners of the electrical arts to master certain laws of electricity, including, for example, Ohm's law and its impact on the selection of proper wire gauges for electrical circuits. If the gauge is too large, unnecessary expense results; if the gauge is too small, excessive voltage drop can result which may damage motors or other devices in the circuit, and, if the current exceeds the ampacity of the wire, electrical fires can result. Use of the present invention all but assures that the user will become familiar with Ohm's Law and its application to electrical circuits, including mastering wire gauge selection, even for circuits that will be subjected to any of a number of environmental variables (e.g., high or low ambient temperatures). This dramatically improves understanding and enhances certification and licensing. In short, the user learns to accurately predict the effects or results of using different wire gauges in the circuit using knowledge of Ohm's Law and the NEC code book as they attempt to match the target wire gauge. Referring also to FIG. 5, preliminarily one or more interfaces are created to communicate components of the Educational Object 10 to the evaluator and the user. With regard to the user's interface 232, at least two different modes are contemplated: Assessment Mode in which the process of predictive assessment takes place, and Interactive Mode in which online help is displayed or otherwise provided. Preferably, Interactive Mode can be disabled by the evaluator, as desired. In this example, there are preferably three levels of assessment. Level

1 Assessment Mode allows the user to select and adjust voltage and resistance values in an attempt to match a target current value of the Target Object 216. Level

2 Assessment Mode allows the user to select and adjust load and wire gauge values in an attempt to match target current, voltage, and wire length values of the Target Object 216. Level 3 Assessment Mode allows the user to adjust voltage and gauge values in an attempt to match target current, power load, and temperature values of the Target Object 216. Thus, the teaching and assessment process proceeds from theory in Level 1 to practical application in Level 3. In Level 1 Assessment Mode, the user is present with a first circuit diagram 234 including the Target Object 216; a first virtual amperage gauge 236; a second circuit diagram 238 including the Trial Object 220; a second virtual amperage gauge 240; the Trial Controls 222; three virtual buttons 242; a level indicator 244; and an assessment panel 246. The first and second circuit diagrams 234,238 are identical, each being a simple closed loop including a virtual voltage source and the Target Object 216 or Trial Object 220, respectively, which are, in this example, virtual lightbulbs. The brightness of the light bulbs depends on the amperage of the electric current within the electric circuit. The first and second virtual amperage gauges 236,240 provide more quantitative indications of the amperage in each electric circuit. The Trial Controls 222 comprise a first virtual sliding switch 222a that controls and allows for adjusting the electrical resistance (in Ohms) of the light bulb, and a second virtual sliding switch 222b that controls and allows for adjusting the DC voltage (in Volts) applied to the light bulb. The three virtual buttons 242 include a Test button 242a selectable by the user to cause the computer program to call the Evaluation Function 24 to assess any adjustment made by the user to the Trial Controls 222 and to update the Trial Object 220 to reflect such adjustment; an Assessment button 242b selectable by the user to call the Assessment Metric 26 to cause a record of the user's performance to be displayed in the assessment panel 246; and a Help button 242c selectable by the user to cause the interface 232 to switch to Interface Mode and display online help in the form of visual, audible, or other assistance for using the interface 232. The level indicator 244 communicates which level the of assessment is being performed. The assessment panel 246 displays the aforementioned record of the user's performance, including the number of tries required to reach a match. In this example, an additional resource, a virtual calculator 250, is provided for the user for performing Ohm's Law calculations. As mentioned, the Interactive Mode provides online help for the user. This help may include, for example, a simulation of the process that occurs in the Assessment Mode. Interactive Mode also provides a non-assessment feature that allows the user to experience and familiarize him or herself with the process occurring in the Assessment Mode without being assessed. With this feature, adjustments made to the Trial Controls 222 are reflected in the Target Object 216 in real-time, which allows the user to gain a preliminary understanding of the effects of different manipulations of the Trial Controls 222 before entering the Assessment Mode and having his or her performance assessed. In this example, there are preferably three levels of non-assessment interactivity. Level 1 1nteractive Mode presents an interface that is similar or identical to the interface 232 presented in Level 1 Assessment Mode except that, as mentioned, the user's adjustments are reflected in real-time (the Test button 242a has no effect in this mode). This allows the user to explore the implications and effects of Ohm's Law. Level 2 Interactive Mode presents an interface that is similar or identical to the interface presented in Level 2 Assessment Mode except that, as mentioned, the user's adjustments are reflected in real-time. Thus, the user is provided with load, wire gauge, wire length, and voltage controls. This allows the user to explore the effect of Ohm's Law on voltage drop. Level 3 Interactive Mode presents an interface that is similar or identical to the interface presented in Level 3 Assessment Mode except that, as mentioned, the user's adjustments are reflected in real-time. Thus, the user is provided with current, load, wire gauge, wire length, voltage, and temperature controls. This effectively provides the user with a wire gauge "calculator" that allows him or her to explore the varying relationships between a number of real-world factors and considerations. As mentioned, it will be appreciated that Educational Objects 10 can be authored or created to model a variety of concepts or conceptual relationships present within epistemic models. In addition to the Ohm's Law and wire gauge example described above, other possibilities include, for example, teaching a process of color matching wherein the user adjusts color components of the Trial Object until its color matches the color of the Target Object, or teaching a process of spatial or geometric recognition wherein the user adjusts side, length, and angle components of the Trial Object until its shape matches the shape of the Target Object. From the preceding discussion it will be appreciated that the present invention provides a number of substantial advantages over the prior art, including, for example, merging learning and assessment to provide dramatically improved understanding of essential concepts. Testing has shown that the method of the present invention allows users to learn essential concepts in approximately one quarter of the time required by traditional teaching techniques. Furthermore, the method of the present invention also advantageously provides a standardized mechanism for evaluating user understanding or performance; allows for criterion referenced assessment using multiple configurations of the Educational Object; and allows for team predictive performance assessment. Although the invention has been described with reference to the preferred embodiments illustrated in the attached drawings, it is noted that equivalents may be employed and substitutions made herein without departing from the scope of the invention as recited in the claims. It will be appreciated, for example, that the specific details of each Educational Object and its various components will vary substantially depending on the concept or conceptual relationship involved. Having thus described the preferred embodiment of the invention, what is claimed as new and desired to be protected by Letters Patent includes the following:
