The present invention relates to a method for indicating characteristic of problem and problem set, more particularly, to a method for indicating characteristic of problem and problem set, wherein characteristic of problem and problem set can be determined and can be visualized.
Learning through problem solving and status evaluation through problem solving are one of the most widely used learning methods to gauge learner's understanding after a learner learns new knowledge.
However, in order to effectively use the results of problem solving, it should be noted what is the weak point of the learner through relevant problems. For this, some workbooks describe which concept or which chapter each problem is based on.
Accordingly, learners solve problems, and then, they can note on which concept or on which chapter they have weak understanding through the concept and relevant information of such concept, which are related with the problems to which they made wrong answers. Learners can effectively supplement weak points through proceeding additional learning with respect to the noted weak concept or noted weak chapter.
Basic level problems are made based on only one concept, thus they can be solved through learning one chapter. However, applied or advanced problems are made based on a plurality of concepts and chapters.
Conventionally, problems made based on a plurality of concepts and chapters, were simply indicated as being based on concept or chapter, which is learned at the very last in a general course of study. Therefore, according to such prior art, learners could only obtain a simplified information regarding problems, and it was not easy to obtain a precise feedback.
For example, in case a learner solves a math problem indicated as being related to an integral calculus but makes a wrong answer due to a wrong understanding regarding a geometry, it can be noted that the learner lacks understanding on the integral calculus, which is learned after the geometry.
Further, according to prior art, learners were provided with a simple list of concepts and chapters related with problems, thus learners could obtain just a fragmentary information related with problems. Furthermore, according to prior art, it was not easy for learners to note overall characteristic (or tendency) of a set of a plurality of problems such as a college scholastic ability test or a mock examination.
As described above, because it was not easy to obtain precise information on characteristic of each problem according to prior art, it was not easy to obtain precise information on overall characteristic of a problem set, in which each problem contains a plurality of concepts variously.
For example, in case of a college scholastic ability test, the proportion among chapters has been maintained similarly every year, thus it can be analyzed that most college scholastic ability tests have similar characteristics when using prior art analysis method. However, the college scholastic ability test actually has different characteristic year by year, thus the analysis using prior art method cannot have high reliability.
Even in the case that the above-described simplified indication is not conducted with respect to problems made based on a plurality of concepts or chapters in prior art, the characteristic of a problem set can be a mere aggregation of concepts or chapters, on which each problem is based, according to prior art. According to such prior art, in the process of analyzing characteristic of a problem set, it is hard to distinguish problem 1, which is based on two combined concepts of limit and similarity of figures, from problem 2, which is based on separate concepts of limit and similarity of figures, thus precise analysis is hard to achieve.
An objective of present invention, which starts from recognition of above-described prior art problems, is to provide method for indicating characteristic of problem and problem set, in which characteristic of problem and problem set can be precisely noted using correlations between attributes.
A different objective of present invention is to provide method for indicating characteristic of problem and problem set, in which characteristic of problem and problem set can be visualized by indicating attributes as points and indicating correlations between attributes as lines.
A further different objective of present invention is to provide method for indicating characteristic of problem and problem set, in which the appearance of a point corresponding to a specific attribute becomes different according to frequency of accumulation of the specific attribute, and the appearance of a line corresponding to a specific correlations between attributes becomes different according to frequency of accumulation of the specific correlations between attributes, when the attributes are indicated as points and the correlations between attributes are indicated as lines.
A further different objective of present invention is to provide method for indicating characteristic of problem and problem set, in which the correlations between attributes related with characteristics of problems to which a learner makes a right answer is indicated as a different line in appearance from the correlations between attributes related with characteristics of problems to which a learner makes a wrong answer.
A further different objective of present invention is to provide method for indicating characteristic of problem and problem set, in which locations of points corresponding to specific attributes are fixed or variable on a screen, in case points corresponding to attributes are displayed on a screen.
Technical objectives of the present invention are not limited to the above-described objectives, and another technical objectives will be able to be clearly understood by a person skilled in the art with reference to the following description.

Embodiments of the present invention will be described hereinafter with reference to the accompanying drawings, in which some embodiments are shown. Advantages and features of some embodiments and methods of accomplishing the same are hereinafter detailed with reference to the accompanying drawings. The present invention is embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure shall be thorough and complete, and shall fully convey the scope of the present invention to those skilled in the art. The present invention is only defined by the category of the following claims. The same reference numbers indicate the same components throughout the specification.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention belongs. Further, unless defined otherwise, all terms defined in generally used dictionaries may not be overly interpreted.
The terms used in the present disclosure are merely for illustration of embodiments, and are not for limiting the present invention. In this disclosure, the use of the terms “a” and “an” and “the” and similar referents in the context of describing the present invention is to be construed to cover both the singular and the plural, unless indicated otherwise. The term “comprising” is to be construed as open-ended terms (i.e., meaning “including, but not limited to,”) unless otherwise indicated.
Hereinafter, the method for indicating characteristic of problem and problem set according to embodiments of the present invention will be described with reference to the drawings. The method for indicating characteristic of problem set will be described first, and then the method for indicating characteristics of problems will be described.
The method for indicating characteristic of problem set according to the first embodiment of the present invention will be set forth with reference to
However, in some embodiments, a method for indicating characteristic of problem set, which includes less steps or more steps than the steps depicted in
In the method for indicating characteristic of problem set according to the first embodiment of the present invention, the problem set only needs to include a plurality of problems, and there is no other limitation. For example, the problem set can be a problem sheet edited for one time use such as a problem sheet of the college scholastic ability test, but is not limited thereto. The problem set can be defined as a plurality of problems selected for analysis. A plurality of problems that a learner has already finished solving can also be a problem set.
Because the problem set includes a plurality of problems, the characteristic of the problem set can be determined as a union of characteristics of all problems included in the problem set. As such, because the characteristic of the problem set can be defined as a union of characteristics of all problems included in the problem set, the characteristic of the problem set can be understood as an extended concept of the below described characteristic of problem, and can include a union concept.
According to the method for indicating characteristic of problem set according to present embodiment, since it is possible to correctly indicate the characteristic of the problem set including a plurality of problems, it becomes possible to easily understand the tendency of the problem set and so forth. For example, the method for the present embodiment can be used to understand a learning history of a learner.
In the meantime, for convenience of explanation, examples of math problems or a problem set including math problems are made for explaining the method for indicating characteristic of problem set according to the present embodiment, but it is apparent to those skilled in the art that the method for indicating characteristic of problem set according to the present embodiment is not applied only to the math problem set, but it can be applied to various subjects such as literature or English, and it can also be applied to various subjects, which are not included in a curriculum.
First, with reference to
Characteristics of problems can be expressed using attributes. The attributes can be evaluation elements that the problem maker tries to evaluate through the problems, or can be defined as specified elements which are expected to be necessary for a learner to solve the problem set or problems, but are not limited thereto. Here, attributes are directed, for example, to concepts that are used or learned in related subjects, or to learners' ability (for example, ability in memory work, understanding and application), or to chapters of a subject, or to specific terms or expressions constituting problems, but are not limited thereto as long as they meet the definition described above.
Also, the attributes defined in the present step (S10) are not just for expressing a characteristic of one problem. The union of attributes for expressing characteristics of all problems included in the problem set or characteristics of all problems which can be made with regard to the subjects or chapters related to the problem set, can be defined. For this, in the present step (S10), a plurality of attributes can be defined.
A step for defining a plurality of attributes can consider subjects, chapters and so on of the problems included in the problem set. In case the problems included in the problem set are math problems, a plurality of attributes can be defined as a plurality of attributes related with math. For example, sequence, limit, similarity of figures and so on can be defined as a part of a plurality of attributes, but are not limited thereto.
The method for indicating characteristic of problem set according to present embodiment can be implemented, for example, by a system indicating characteristics of problems or characteristic of problem set described below. Therefore, the attributes defined in the present step (S10), can be indicated as corresponding codes. Here, the codes can be formed as combination of characters, numbers and so on, but are not limited thereto. For example, the code corresponding to the equation and inequality can be “C426,” and the code corresponding to the sequence can be “C382,” but is not limited thereto.
In some embodiments, with regard to each subject or each chapter, a plurality of attributes can be defined and saved in advance. In such a case, the present step (S10) can be skipped while implementing the method for indicating characteristic of problem set according to the present embodiment.
Subsequently, with reference to
In the present step (S20), with regard to all problems included in the problem set, the characteristic of each problem can be determined. That is, for each problem, the present step (S20) can be repeated, and the characteristic of each problem can be determined by attributes related with each problem and correlations between the attributes. Specifically, in case the number of attributes related with certain problem is more than one and the number of correlations between the attributes is more than one, the characteristic of that problem can be determined as a union of attributes related with that problem and a union of the correlations between the attributes.
For this, with reference to
First, with reference to
Here, attributes related with each problem are selected since they are identified as being related with each problem among a plurality of attributes defined in the previous step (S10). The description that some attributes are related with a problem can mean that those attributes are necessary for a learner to solve the problem or that those attributes are used in the formation of the problem. Here, in case that the number of attributes related with each problem is more than one, a plurality of attributes can be identified.
For example, with reference to
With reference to
Here, the correlations between the identified attributes can be found by determining whether there exist correlated attributes between attributes related with the problem. In case a plurality of attributes need to be applied at the same or different time in order to solve the problem, it can be defined that these plurality of attributes are correlated with one another. Further, in case a plurality of attributes need to be applied at the same or different time in order to create the problem, it can be defined that these plurality of attributes are correlated with one another. Therefore, according to the method for the present embodiment, the analysis can be conducted not only by using the attributes, but also by using the correlations between the attributes, which leads to a more precise analysis result.
For example, with reference to
Between identified attributes, a plurality of correlations may be found. In this case, after finding the plurality of correlations between the identified attributes, the characteristic of a problem can be determined by the identified attributes and the plurality of correlations. For example, with reference to
As described in the above example, the correlation can exist only between parts of identified attributes. For example, with reference to
In the meantime, in some embodiments, when a plurality of attributes are identified, the correlations can exist between all of the identified attributes. For example, in case the first to third attributes are identified, which are related with a specific problem, the correlations can exist between all combinations of the first to third attributes. That is, all of the correlations between the first attribute and the second attribute, between the second attribute and the third attribute and between the third and the first attribute exist.
It should be noted that when there is only one attribute related with a problem, the correlation cannot exist. Only when there exist a plurality of attributes, the correlation can be found. For example, when there is only one attribute related with a problem, the characteristic of this problem can be determined only by the attribute related with the problem.
According to the method for indicating characteristic of problem set according to the first embodiment of the present invention, the characteristic of each problem can be more precisely indicated, since the correlations between the identified attributes are used in determining the characteristic of each problem.
Subsequently, with reference to
In the method for indicating characteristic of problem set according to the present embodiment, the characteristic of problem set can be determined as a union of attributes of each problem. Since the characteristic of a problem is determined by the attributes related with the problem and the correlations between the attributes, the characteristic of problem set including a plurality of problems is not merely comprised of a union of the attributes, but can include a union of all correlations included in the characteristic of each problem.
For example, with reference to
Therefore, according to the method for indicating characteristic of problem set according to the first embodiment of the present invention, it can be easily noted how a problem included in the problem set is structured through the characteristic of the problem set. A more specific information than prior art technology is available.
Subsequently, with reference to
Specifically, the attributes included in the determined characteristic of problem set are indicated as points on a screen and the correlations between the attributes are indicated as lines on a screen, when the determined characteristic of problem set is visualized on a screen. Here, the attributes can be indicated on a screen, for example, as points on a screen, but are not limited thereto. They can also be indicated by various marks other than a point.
For example, with reference to
Therefore, according to the method for indicating characteristic of problem set according to the first embodiment of the present invention, a learner or a user can easily note the characteristic of problem set through the visualized screen. That is, a learner or a user can easily understand which attributes are used in the problem set and how the attributes are combined with each other for use.
In a step of visualizing the determined characteristic of problem set on a screen (S40), it is not limited to indicate only the attributes included in the determined characteristic of problem set on a screen. It is also possible to indicate all of attributes defined in the attribute defining step (S10) on a screen other than the attributes included in the determined characteristic of problem set.
For example, with reference to
As such, according to the method for indicating characteristic of problem set according to the first embodiment of the present invention, the characteristic of problem set can be correctly indicated through the correlations between attributes, and such characteristic of problem set can be visualized, thus a learner or a user can intuitively understand the characteristic of problem set.
Specifically, with reference to
Moreover, with reference to
For example, with reference to
Hereinafter, with reference to
Differently from the method for indicating characteristic of problem set according to the first embodiment of the present invention, in the step of visualizing determined characteristic of problem set, the attributes included in the determined characteristic of the problem set and the correlations between the attributes can be visualized on a screen in sequence in a unit of each problem's characteristic.
That is, in the method for indicating characteristic of problem set according to the second embodiment of the present invention, characteristics of all problems of a problem set are not simultaneously visualized on a screen at one time, but a characteristic of one problem of a problem set is visualized on a screen and a characteristic of the other problem in the same problem set is visualized thereafter.
For example, with reference to
According to the method for indicating characteristic of problem set according to the second embodiment of the present invention, since the characteristics of problems are displayed separately from each other, the characteristic of each problem can be sequentially noted.
Hereinafter, with reference to
Differently from the method for indicating characteristic of problem set according to the second embodiment of the present invention, in the step of visualizing determined characteristic of problem set according to the method for indicating characteristic of problem set according to the third embodiment of the present invention, the attributes included in the determined characteristic of the problem set and the correlations between the attributes can be visualized on a screen accumulatively in a unit of each problem's characteristic.
Specifically, according to the frequency of accumulation of an attribute, the appearance of the point corresponding to the attribute can become different, and according to the frequency of accumulation of a correlation between attributes, the appearance of the line corresponding to the correlation can become different. Here, the appearance of the point can mean the size, shape, color and the like, and the appearance of the line can mean the thickness, shape, color and the like, but is not limited thereto.
For example, with reference to
According to the method for indicating characteristic of problem set according to the third embodiment of the present invention, the characteristic of problem set visually displayed on a screen can be accumulatively indicated, thus a learner or a user can easily and directly understand the frequency of the attributes and the frequency of the correlations between the attributes, which leads to a more precise and easier analysis of the characteristic of problem set.
Hereinafter, with reference to
Differently from the method for indicating characteristic of problem set according to the first embodiment of the present invention, appearance of a point corresponding to a specific attribute becomes different according to the frequency of the specific attribute included in the determined problem set, and appearance of a line corresponding to a correlation between specific attributes becomes different according to the frequency of the correlation between the specific attributes included in the determined problem set, in the step of visualizing determined characteristic of problem set on a screen, according to the method for indicating characteristic of problem set according to the fourth embodiment of the present invention.
That is, with reference to
In contrast, with reference to
Specifically, with reference to
According to the method for indicating characteristic of problem set according to the fourth embodiment of the present invention, since the frequency of attributes and the frequency of correlations between attributes can be intuitively understood through the accumulative indication of characteristic of problem set, which is visually displayed on a screen, a more precise understanding of characteristic of problem set is possible.
When using the method for indicating characteristic of problem set according to the above-described embodiments of the present invention, since the characteristic of problem set learned by a learner can be indicated, the current status of a learner or the learning history of a learner can be visually understood.
Hereinafter, with reference to
With reference to
According to this, with reference to
For example, the correlations between attributes related with the third problem, which is found to be right solution according to the marking result, can be displayed as a blue line. Also, the correlations between attributes related with the first problem, which is found to be wrong solution according to the marking result, can be displayed as a red line. It should be noted that the color of a line corresponding to the correlation related with the problem of right solution only needs to be different from that of a line corresponding to the correlation related with the problem of wrong solution, thus the color is not limited to blue or red.
In some embodiments, the appearance of a line corresponding to correlations between attributes does not become different according to the result of right or wrong solution in a unit of problem. The right or wrong solution can be determined in a unit of correlation between attributes. For example, in a case that a user selects an answer identified when he or she does not correctly understand correlation between specific attributes, his or her selection may be found to be wrong solution with respect to the correlation between the specific attributes, but it may be found to be right solution with respect to correlation between different attributes in the same problem. For example, with reference to
Specifically, with reference to
As such, according to the method for indicating characteristic of problem set according to the fifth embodiment of the present invention, the color of lines corresponding to the correlations related with the problem of right solution differs from the color of lines corresponding to the correlations related with the problem of wrong solution. Thus, when focusing on the color of lines related with the problem of wrong solution, the weak points of a learner can be easily identified. Moreover, it can be easily identified how many times a learner made right or wrong solutions with respect to a single correlation, thus a more precise analysis of a learner becomes possible.
Hereinafter, with respect to
With reference to
That is, when the population of the attributes are determined, it can be determined on which location of a screen the point corresponding to each attribute is indicated. As such, the characteristic of problem set can be visualized while the location of a point corresponding to specific attribute is fixed.
Therefore, according to the method for indicating characteristic of problem set according to the sixth embodiment of the present invention, when comparison is made between different problem sets, different problem sets can be indicated in identical coordinates. Thus, with reference to
Hereinafter, with respect to
According to the method for indicating characteristic of problem set according to the seventh embodiment of the present invention, in a step of visualizing determined characteristic of problem set, the location of a point corresponding to specific attribute can be variable, non-fixed type or movable on a screen. For example, the attributes having a lot of correlations or found to be important can be indicated as collection of points on a screen. Also, the frequently included attributes may be indicated collectively in the middle of a screen. That is, the location of a point corresponding to specific attribute is not fixed on a screen, thus the visualization according to characteristic of each problem set becomes easier for a user to understand.
Hereinafter, with respect to
According to the method for indicating characteristic of problem set according to one embodiment of the present invention, as depicted in
However, it should be noted that the attributes defined in this step (S10) are not for expressing characteristic of a specific problem. In this step (S10), a population of attributes can be defined for expressing characteristics of all problems, which can be set as exam problems with respect to a subject or a topic related with those problems. For this, a plurality of attributes can be defined in this step (S10).
Thereafter, with reference to
Thereafter, with reference to
Therefore, according to the method for indicating characteristic of problem according to one embodiment of the present invention, both of attributes related with the problem and the correlations between attributes are considered to determine characteristic of the problem, thus precise analysis regarding the characteristic of problem becomes possible. Moreover, according to the method for the present embodiment, since the determined characteristic of problem is expressed visually, intuitive analysis of problem becomes possible.
Hereinafter, with reference to
With reference to
The attribute defining part (10) can define a plurality of attributes for expressing characteristic of problems included in problem set or for expressing characteristic of problem. The defined plurality of attributes can be stored in an attribute database (11) included in the attribute defining part (10).
In some embodiments, a plurality of attributes can be pre-stored in the attribute database (11), but is not limited thereto.
The problem characteristic determining part (20) can determine characteristic of each problem included in problem set, or can determine characteristic of a single problem. The characteristic of each problem can be determined by attributes related with the problem and correlations between the attributes.
Specifically, the problem characteristic determining part (20) can include an attribute identifying part (21), which identifies attributes related with problem, and a correlation identifying part (22), which identifies correlations between identified attributes.
The problem set characteristic determining part (30) can determine characteristic of problem set. It determines characteristic of problem set as a union of characteristics of all problems included in the problem set. The characteristic of problem set can be determined by attributes related with all problems and correlations between the attributes.
The visualization part (40) can visualize determined characteristic of problem set or characteristic of problem on a screen (not depicted).
The embodiments of the present invention are described with reference to the accompanying figures, but a person having ordinary skill in the field of the present invention may understand that the present invention can be implemented differently without changing the technical concept or essential elements. Therefore, the above-described embodiments are exemplary and not restrictive in all aspects.
