1 Urgency of the theme

The fourth scientific and technological revolution (CMCN 4.0) has impactedand made a great change to the life, economy, society and education of most countries

in the world Industrial revolution 4.0 requires education to apply IT in the educationprocess, changing the thinking and approach, methods and means of teaching andlearning in the direction of education 4.0 (transforming the way education from thetransmission of knowledge into development of qualities and abilities for students:creative ability, language ability, and ability to establish relationships or teamworkskills) in order to adapt to changes in social practice

Education of Vietnam before the 4.0 era, in front of the need to innovate The

Central Resolution II, Session VIII affirmed: "Reform education - training methods,

overcome the one - way transmission, training into the creative thinking of learners Step by step applying the advanced methods and modern methods in the teaching process, ensuring conditions and time for self-study, self-study for students " Thus,

the general orientation of teaching method innovation is the diversified and reasonableuse of teaching methods in the direction of promoting activeness, initiative andcreativity of students, transforming the teaching form of transmissing knowledge intothe form of teachers organizing activities for students to perceive independently

In recent years, education of Vietnam has the development steps but there aremany limitations, especially the education of history Students do not know and do notlike to study, the quality of history is reduced, not meet the requirements of socialreality Therefore, the improvement and renewal of content and teaching methods ofthis subject is an urgent matter which must be conducted regularly and synchronously.The graph has been the best means of teaching in many fields and in manyfields of education in Vietnam However, in the teaching practice in general, historyteaching in particular, teachers only use the graph as a visual means to support theteaching process but not use it as an active teaching method Moreover, the process ofdesigning, using the graph is mainly in single direction, teachers are the person whobuild and use the graph according to the experience of individual, students are theobject to receive the graph models passively In particular, the constructing andreading skills and graph using skills of students are very weak Besides, the use ofgraph in teaching has not followed a certain principle, teachers have not maximizedthe positive, initiative of students in the learning process so the efficiency is not veryhigh

The history of Vietnam from 1919 to 1975 at High School is the focus contentwith many important events through three periods: the Communist Party of Vietnamwas established in 1930; The successful August Revolution led to the establishment ofthe Democratic Republic of Vietnam (1945); The anti-French resistance ended withthe historic victory of Dien Bien Phu (1954); The anti-American resistance saved thecountry in the joy in Spring 1975 With three historical periods, long knowledgevolume, many events are difficult for students to learn and remember so it is thechallenge for teachers and students Using the knowledge diagramatizing method toteach this part, it helps to minimize difficulties in students' perceptions and helpsstudents to generalize the basic knowledge contents in a systematic way, especially

Trang 6

students can compare and contrast contents of knowledge in two French and American wars From there, students will know the development period of nationalhistory through each important event that is expressed in the form of graph.

anti-Based on the theoretical and practical basis as mentioned above, we selected

orientations for this author to continue studying to solve problems in chapter 2,chapter 3 and chapter 4 of this thesis

1.3 General assessment of research result of the published documents and the arisen issues for this thesis to continue solving

Firstly, basing on the study of the documentation sources, we continue to build

and perfect the theoretical foundation system of knowledge diagramatizingmethodologies in the teaching in general and teaching history at high school inparticular

Secondly, investigate and survey the actual state of teaching history and the use

of knowledge diagrams to assess the feasibility and efficiency when applying theknowledge diaramatizing method in teaching history at high schools

Thirdly, learn about contents of Vietnamese history program (1919-1975) to

determine content of basic knowledge that may be designed knowledge diagrams tohelp students to acquire quickly and efficiently during their learning period

Fourthly, study and put forth the process and steps for designing knowledge

diagrams in teaching history at high schools

Fifthly, suggest the pedagogic method groups when using knowledge diagrams

in teaching history of Vietnam (1919-1975) at high schools

Trang 10

Sixthly, prepare lessons and implement the pedagogic experiment (each part

and total parts) at grade 12, thus, generalize the suggested methods when using theknowledge diagramatizing method in teaching history at high schools

Chapter 2 KNOWLEDGE DIAGRAMATIZING METHOD IN TEACHING HISTORY AT

HIGH SCHOOL: THEORY AND PRACTICE 2.1 Theoretical basis

2.1.1 Conception of the knowledge diagramatizing method in teaching

history * Graph, diagramatizing

Graph means a kind of conventional visual instrument that is used in the

teaching process Graph is the system of keywords and images of the same systemcombining with symbols to reflect the object during the awareness process

Diagramatizing means the action takes place in thinking to modelize a thing,

the phenomenon of nature and society in a schematic language to make it easy toperceive it Diagramatizing is considered as a teaching method to express knowledgecontent in a diagrammatic language The schematic language is a system of symbols,cubes, colors, dimensions, scales used to specify or generalize the knowledgecontent shown on the diagram

*Knowledge, historical knowledge

Historical knowledge means the basic knowledge in the history subject that is

confirmed by science, selected by scientists and recorded in the historical textbook ofhigh school Historical knowledge includes events, phenomena, rules, concepts, time,places, characters, etc Through this, it impacts on historical awareness and makes thehistorical awareness to be specific, comprehensive and systematic

*Knowledge diagramatizing, history knowledge diagramatizing

Knowledge diagramatizing is the form to arrange knowledge according to the system of symbols, cubes, colours This arrangement should be based on specific

purposes, content, requirements and principles and it is categorized into diagrammaticforms

*Diagramatizing method

Diagramatizing method means the forms and uses of graph to organize the

teaching with certain purpose and plans in order to improve the efficiency of lessonsand quality in teaching subjects

2.1.2 Knowledge diagramatizing types in teaching history at high

schools * Flow charts

Flow chart was researched and used by American engineers, namely Frank andGibreth since 1921 This is a chart form using simple cubes, symbols, logo, colour toarrange the system according to a detailed chart Each cube expresses an unit ofknowledge and combines with each other by links to describe relationship amongcubes in this system Sometimes, it is also called process chart, process diagram

Trang 11

Figure 2.1: Flow chart

* Mindmap

Mindmap is the act of arranging ideas, knowledge content to create images inthinking for a problem or a content from familiar images, which are captured in theform of maps Mindmap can break down the phenomenon into details orgeneralizations of the details into the system while retaining the linkage andsystematization of the problem

Figure 2.2: Mindmap

* Fishbone diagram

Fishbone diagram is an action that uses a simple drawings and symbols tosort according to a fish bone-like system The fishbone diagram is used to identify thecause of the problem, to analyze the cause, to categorize the cause in order to provide

a specific solution to solve the problem

Figure 2.3: Fishbone diagram

* Venn diargam

Schematic diagram or Venn diagram was built by Jonh Venn in about 1880

circles; each circle contains all the elements of a set Usually two or three circles, morecircles, the problem becomes more complicated Similarity among the groups, ideas,and problems are shown in the overlapping parts of the circle, the differences areshown in the non-overlapping part of the circle

Trang 12

Figure 2.4: Venn diagram

* Timeline

It is called as Timeline, English-Vietnamese dictionary defines: Timelinemeans progress In Vietnamese, the timeline is understood as the way in which thingsare arranged in chronological order by diagrams In practice, it is possible to use atimeline to list typical events in chronological order to determine the location of theevent, the phenomenon at a particular time, or to understand the overall development

of events in a period or process

The classification of the above map is only relative, based on the characteristics

of the timeline, the design should be based on the purpose, requirements, tasks andcontents of the knowledge so that the use process is effective and suitable with thelevel of awareness of students

2.1.3 Characteristics of knowledge mapping in history teaching at High Schools

Knowledge mapping in teaching history includes the following characteristics:Objectivity and subjectivity; Generalization; Logic, system; Basicity, nature; Intuitive;High transferability; Flexibility

2.1.4 The advantage of the method of mapping knowledge in teaching history in high school

Theoretically: The transformation of the mathematical diagram method intothe method of knowledge mapping in teaching will help to arrange knowledge in alesson, a chapter, a process into a system with close relationship together help studentsunderstand the nature of the knowledge arranged in diagrams In addition, the method

of knowledge mapping also helps teachers and students use knowledge diagrams toorganize teaching activities in the direction of positive student learning activities,thereby contributing to improving efficiency lesson

Trang 13

In practical terms, when using the method of mapping knowledge to teach, it will firstdraw attention to students; The method of teacher knowledge mapping can incorporatemany different teaching methods; The method of knowledge mapping has advantages

in organizing various forms of teaching and diversity; The method of knowledgemapping also helps students orient learning methods; Methods of mapping knowledgecombined with teaching techniques modeled in the form of activity diagram willmobilize all students in the class to participate in learning activities under theorganization and guidance of teachers Teaching by mapping the knowledge, teachersand students does not take too much time on writing, drawing and deleting on theboard

2.1.5 Orientation of innovation in teaching history at High School

At present, innovation of education in our country is concretized through theInstructions, Resolutions of the Party, the National Assembly and the Government;Education Law in 2009; Resolutions of the 8th Party Central Committee – Session XI

on the radical renewal of Education and Training after 2015 Therefore, the use ofmapping method in teaching history will be one of the important measures to raisequality of subject It contributes to enrich the method system of teaching history athigh schools in order to carry out the renovative task of teaching methods at highschool in our country in this period

2.1.6 Role, significance of knowledge mapping in teaching history at high schools

Based on the objectives of subject, content of knowledge and the purposes,requirements of teaching, the mapping method has the following role: Knowledgemapping is the visual means of teaching history; Knowledge mapping is a way torenovate the history teaching methods; Knowledge mapping is both a teaching tooland an active teaching method

The use of knowledge mapping is not only meaningful in all three aspects ofbringingup, education and development, but also it forms general abilities in thestudents, specific abilities of subject, contributing to the form and development in ourchildren with the core qualities, in line with the objectives of general education

2.2 Practical basis

2.2.1 Purpose, location and object of the survey

Purpose: Understanding the actual state of teaching history, the use of

knowledge mapping methods in teaching history at high schools; suggesting themethod of using knowledge mapping in teaching history at high schools

Location: Some high schools in three regions: North, Central region and

South However, to make convenience for this process, we conducted to teach theexperimental lessons and we focused on survey in the Northwest

Object of the survey: We conducted a survey of 117 history teachers and 1,548

students of 36 classes in 19 high schools across the country

2.2.2 Content, period and method of survey

Content of survey focuses on 4 groups of questions as follows: Perception of

teacher and student about history at some high schools across the country; Practicaluse of knowledge mapping in teaching history at high schools; Construction processand measures using knowledge mapping in teaching history at high school;Difficulties, recommendations when using the knowledge mapping method in teaching

Trang 14

history The survey period is performed during the school year 2016-2017, and school year 2017-2018 Survey method: Use the questionnaire developed by the question

system to collect the answers; data analysis through survey results; interviews forteachers and students; attendance; consult experts

2.2.3 Evaluation of survey results

Through investigation, practical survey shows that the use of diagrams asteaching aids, not using the diagrams as an active teaching method, most teachers areconfused in the design and flexible use in the teaching process, students use thediagrams to observe, take notes, but do not use mapping as an effective learningmethod Based on theoretical and practical research, we found that the choice of types

of diagrams to organize learning activities is a positive measure contributing to theinnovation of teaching methods in general and history teaching methods in particular

at high schools

Chapter 3 KNOWLEDGE MAPPING IN TEACHING VIETNAMESE HISTORY

(1919 – 1975) AT HIGH SCHOOLS 3.1 Location, target and basic contents of Vietnamese history program (1919 – 1975) at high schools

Location: Vietnamese History Curriculum (1919-1975) is part of the 12th grade

history program at high school level History program of grade 12 consists of twocourses: World history section and Vietnamese history section are taught in 52.5periods Vietnamese history from 1919 to 2000 was followed by the modern worldhistory from 1945 to 2000 The historical period from 1919 to 1975 was composed of

12 lessons, occupying 30 periods, not including 5 periods of review and test

Target: Based on the program of general education in History and based on the

program of history textbooks in grade 12 at high school, standards of knowledge, skillsand attitudes in History as regulated by the Ministry of Education and Training,teaching the Vietnamese historical module from 1919 to 1975 to achieve the goals ofknowledge, skills, attitudes and development of general abilities and specific abilitiesfor students

Basic knowledge contents of Vietnamese history (1919-1975) at high school

Vietnamese history (1919-2000) according to the instructions of knowledgestandard, skills of History of grade 12, divides into 5 periods: 1919-1930; 1930-1945;1945-1954; 1954- 1974 and 1975- 2000 Within the research scope of this theme, wesumarize the basic knowledge contents from 1919 to 1975

3.2 Design of knowledge mapping types in teaching Vietnamese history (1919 – 1975) at high school

Basic requirements for designing the knowledge map in teaching history:Ensure the knowledge volume to build diagrams; To agree on the objectives,contents and teaching method; Ensuring scientific integrity; In accordance with thelevel of awareness, promote the positive, initiative, creative in learning of students;Ensure the consistency of symbols, colors, and cubes those are conventionally plotted

on the diagram

The knowledge mapping process for historical lessons at high school consists

of 5 steps, which are concretized in the diagram below:
