Research On The Influence Of Digital Blackboard Writing In Students' Domain Knowledge Learning

Contextualization is the essential attribute of knowledge.The knowledge cannot be out of context,otherwise it will turn to be normal information.When learners try to extract knowledge,they must reconstruct the previous learning situation.In the traditional classroom,blackboard as a teaching resource which is full of contextualiald information haven't been given enough attention,even if a well-designed writing on the blackboard will be erased due to its inconvenient in storage,let alone to use it as a significant learning resource during review period.Digital Blackboard Writing is a unique way of knowledge contextualization,it could store the situational elements of each class,and provide a new clues of extracting knowledge,this kind of digital blackboard writing are often consists of situational message from both teachers and students on the class,which could offer students a significant way to remember what they have learned at that class,thereby promoting their academic level.The research aims to prove that digital blackboard writing could be a significant influence on students' learning under the new technical learning conditions.This research direction has been neglected by most research scholars.Through the literature research,research analyses current research of digital blackboard writing and the deeply understands the concept of digital blackboard writing and domain knowledge learning,memory mechanism and other related theories.Under consideration of the digital blackboard writing reality,paper comes up with the main types and the implementation of the digital blackboard writing.In view of the present situation of teaching,together with the questionnaire carried out for teachers and students,research aims to find out problems in current teaching and learning in information technology subject.Through the use of Delphi method and cognitive operation method,research intends to determine the domain knowledge structure of "algorithm and its implementation".In order to give convincing results,research invited experts and experienced teachers in information technology subject to construct the domain knowledge learning of this section from the angle of declarative knowledge,procedural knowledge and conditional knowledge,as well as declare the operational description of the schema.Followed by a three-month group experiment,the study concluded that:Firstly,digital blackboard writing could cause a significantly positive impact on students' learning in domain knowledge learning,such as:1.Students in the experimental group have achieved much better score in overall academic performance than the students in control group.2.Compared to students in control group,students in the experimental group have performed much better in the learning of three types of knowledge(declarative knowledge,procedural knowledge,conditional knowledge).Secondly,digital blackboard writing could cause a significant impact on the different levels of students in the field of domain knowledge learning,such as:1.In the case of Learning-gifted students,digital blackboard writing could have a significant and positive influence on its entire domain knowledge learning,procedural knowledge learning and conditional knowledge learning,but there is no remarkable difference in the study of declarative knowledge.2.In the case of middle-level students,digital blackboard writing have the overall positive influence on its domain knowledge learning,but no impact on the other three kinds of learning.3.In case of learning-disabled students,digital blackboard writing has a significant and positive influence on its overall domain knowledge learning and the other three kinds of learning.In summary,the study puts forward the technical realization method of digital blackboard writing,and confirms that digital blackboard writing can have a significant impact on students' learning in the field of domain knowledge learning.As a consequence,research suggests that teachers should digitalize their blackboard writing in the traditional teaching environment,so as to promote the students' memory and learning.
