At the node learning characteristic in the learning process of this study node, node evaluation is carried out to the node learning characteristic, according to
Node evaluation result generates the corresponding new learning path of study individual again.
(1) based on test topic, if the associated topics of one of b, student all answers correct, and result is all
It is " correct：It is very determining ", illustrate that student grasps this key node completely, then will remove in the B in adaptive content
This b is " correct if there is removing：It is very determining " outer other result types, then b still retain in B, to ensure to allow as possible
Raw abundant mastery learning content.
(2) initial learning characteristic is exactly the answer result of each b associations topic.
(3) these learning characteristics are used for judging which b can remove before adaptive learning in B, to save student
The time is practised, learning efficiency is promoted.
(1) which data (learning characteristic) of acquisition study individual：Two data, one is total of this study node
The time is practised, the other is this learns the answer result of topic in node.
(2) analysis method (algorithm)：According to learning characteristic, there are two as a result, study passes through and learn not lead to for meeting after analysis
It crosses.
The case where study passes through：If without topic in node, no less than teacher's preset minimum duration when study,
As pass through；If there is topic in node, topic is completely correct, no matter whether study duration is more than minimum duration, all sentences
To pass through；If there is topic in node, topic is not totally wrong, and learns duration and be no less than minimum duration, is judged to pass through.
The case where study does not pass through：If being less than teacher's preset minimum duration when learning without topic in node,
It is judged to not pass through；If node has topic, the complete mistake of topic to be judged to not pass through；If node has topic, topic endless
Total correctness, and learn duration and be less than minimum duration, it is judged to not pass through；If there is topic, topic whole mistake, no matter learn duration
Whether it is no less than minimum duration, is all judged to not pass through.
(3) new learning path is obtained according to feature：
Divide two ways：A. being inserted into after b. key nodes have learnt without assessment page after key node has learnt has assessment page to insert
Enter
a：It is inserted into without assessment page, the learning characteristic for being completely dependent on key node b carries out adaptive path planning
If being judged to pass through according to feature, the study of next key node is entered directly into.
If being judged to not pass through according to feature, it is inserted into additional study node.
b：There is assessment page to be inserted into, then the assessment result for being completely dependent on assessment page carries out adaptive path planning
Preceding test question of the content with push of page is assessed, difference lies in topic only has around the key node b just learnt
Content, be not related to the relevant topic of other key nodes.
Appraisal procedure is different from preceding test, regular relative loose：The submission of only whole topics is combined as " correct：Very
Determine " and it is " correct：Be not sure " when judge pass through, be otherwise all judged as not passing through.
If being judged to pass through according to assessment page, the study of next key node is entered directly into.
If being judged to not pass through according to assessment page, it is inserted into additional study node.
The operation principle of Adaptable System includes：
It is pre-created or splices micro- class；
The crucial micro- class of selection, creates adaptive micro- class；
The crucial micro- class of importing or addition content pages, selecting suitable position to be inserted into assessment page or select has adaptation function
Single choice；
Assessment page is inserted into test topic or selectes with the option adaptively guided；
Score section delimited to be associated with micro- class or be associated with micro- class after particular options.
Further, learning path is the screening displaying to learning node and permutation and combination, it is therefore desirable to learning Content
Carry out node.A kind of common form of node is exactly the knowledge mapping of the course.But the granularity of knowledge mapping is relatively adaptive
It is still higher for should learning, therefore more fine-grained node can also be done.Most suitable granularity is that a study node exists
Be not suitable for being further continued for dividing on learning path：Content order i.e. in node does not have the meaning of permutatation, all the elements
It is impossible to delete or do again the additional supplement being not necessarily to.Certainly, under requirement adaptive in various degree, the rule of node
Mould can also rise, for example can also meet certain adaptive requirement using the granularity of knowledge mapping as study node.
Node is related to the specific content of courses, thus node judgement and structure can in person have been participated in by faculty
At.If knowledge mapping can refine to certain granularity, at the same all teaching materials can be referred to it is every on knowledge mapping
A node simultaneously stamps type label, then the work of node can also be automatically performed by system.The node of the content of courses is
Content basis based on path adaptive learning.
Further, instructional objective can also be split according to the thought of learning Content node, generate several compared with
For specific Small object.Under explicitly teaching Small object, the adaptive learning path being built by study node must be one
The path that item is limited in scope will not completely disengage instructional objective, while can cover some key nodes again.Here cannot jump
It crosses the node for having to learn and is referred to as key node b.It for all key nodes, is indicated with set B, B can also be,
There is no any key node under the learning objective.
There may be the front and back dependences on learning sequence between node and node, for there is clear front and back dependence in B
Node can be indicated with critical path BF.For the difference set of B and BF --- it must be learned by but without the section relied on exact sequence
Point can be inserted by certain rule on the path of BF, can also be by adaptive mode according to the learning characteristic of learner
Selectively it is inserted into more particularly suitable position.In view of all extremely key can not be rejected the learning Content in B, and B interior joints
Put in order and be also easy to generate a subjective Rational Path, therefore the present invention path final to B is simplified ---
It is the identical set of element that all nodes, which have ordinal relation to each other, i.e. B and BF, in acquiescence B, while in the base of B
BF also includes a fixed path relation of sequence on plinth.
Further, it can be considered additional nodes except the learning Content other than BF, be denoted as A, additional nodes structure on BF
The path built out is considered as extra path, is denoted as AF.Therefore the present invention is discussed adaptive, and emphasis is based on additional on BF
The adaptive problem of path AF.When BF is skyOr BF is very short and Instructional Design of faculty focus primarily on AF when
It waits, comparatively the adaptive degree for the adaptive learning that the present invention is discussed can greatly improve.No matter but any journey be increased to
Degree, the adaptive learning that the present invention discusses is all based on do not depart from clear instructional objective under the premise of be unfolded it is adaptive.
A is the supplement of B, for example consolidates, enhancing, extends.For instructional objective, A can help learning ability weaker
Learner preferably reach target, or allow be easy to reach learning objective learner obtain surmount it is more outside set objective
Learning Content and better learning effect.It is exactly the form of AF and BF specific to learning path.There are one usual instructional objectives
Judge the baseline passed, but more than after baseline, is an effect section in fact.Outstanding faculty usually will not only meet
Pass as a result, but obtaining better teaching efficiency in controlled conditions as far as possible.So A have for B it is more important
Meaning, and AF also has very important significance for the adaptive of BF.Perhaps, supplement and promotion are only adaptively most
Big value.
Evaluation point of the present invention is the assessment to assessing section, and assessment section can be that (micro- class is by page for one or more pages
Face is constituted), consider from form consistency, evaluation point can also be shown with an independent page.If assessment is specific
Operate it is fairly simple clear, such as only assessment user which option is had submitted in the page, then evaluation point can not need yet
It is individually shown with a page.
From the dimension of assessment object, assessment is comprising objective and two kinds subjective.Objective i.e. completeness, accuracy, completion
Time, submission the information such as option.Subjectivity can directly allow user to do topic and investigate or test, and the study to obtain user is commented
Valence.
From the purpose dimension of assessment, for example purpose is to find the point of interest of student, then can directly be carried from user
The number duration of the option of friendship or each page browsing determines.
Assessment needs to integrate various data, has certain complexity, therefore still to focus and really use field
Scape and operational effect are adjusted.
To the behavioral data of study：Completeness, duration, submission option, accuracy etc. count, and can be used as objective item
The assessment that mesh is automated.In addition to this it is possible to provide important supplement of the test as assessment.From evaluation learning effect
For purpose, it is the most effective means for comparing other modes to pass a test and carry out assessment.
For learning effect：It is assessed in evaluation point addition test, different AF is guided according to test result.
For user behavior：Corresponding AF is directly linked to after the option of multiple-choice question.
