Trang 3INTRODUCTION
1 Reasons to select topic
The development of Science and Technology today has created a multitude
of high quality products for society in general and in particular education It requires each country to be always creative, adapt promptly to the continuous transformation of life and technology In order to address these challenges, the Education and Training sector should take the lead and undertake the mission to raise the people's intellectual standards, detect and foster talent towards raising the value of gray matter Capacity development, especially self-study capacity (SSC) is becoming the trend in the teaching innovation of many countries around the world
With the rapid development of information technology (IT), digital devices have partly met the needs of teaching and learning in general and Chemistry in particular The Ministry of Education and Training proposed in the Comprehensive General Program that the capacity to apply informatics is one of the ten core competencies which students need to acquire by completing a general education program For this reason, teachers need to form and develop the capacity and application of IT for the students in their own department However, the application of IT itself in teaching and learning especially in the process of self-training, the development of students’ thinking has been limited, have not exploited the strengths of IT
Chemistry is a science with theoretical knowledge and extensive and varied empirical data Learning to understand, remember and use them is always the pressure for the majority of students in high school If there is a software to look
up knowledge and empirical data, it will help students facilitate the use of them to solve assignments as well as to complete other learning tasks Thereby it can help students develop SSC by applying electronic learning and creating excitement for students in learning chemistry
Because of these reasons, we choose and implement the research topic:
"Design and use of chemical knowledge lookup software to develop self-study capacity for students in high school”

Trang 6school has been studied effectively such as effectiveness in applying ICT in
teaching, difficulties in applying ICT in teaching, solutions to improve the efficiency of ICT application in teaching, etc There have been some studies on the factors affecting the ICT application efficiency for teachers and students
However, the problem of determining the ICT application capacity and proposed measures to develop this capacity for students in the high school are still less concerned
1.2 Innovation of Vietnamese education
- The trend of educational development in Vietnam: according to author Jacques Delors ' analysis of UNESCO's reports on education for the XXI century, the world education model of the XXI century is based on four pillars, which is learning to know, learning to do, learning to live together and learning
to be
Due to the extensive impact of science and technology, in the context of a world of information boom and competition to develop, the daily knowledge increase is multipliation, in which multimedia engineering is the type of technique being the most noticeable According to the development momentum
of multimedia engineering, a new teaching form is formed-the appearance of the multimedia computer teaching system Multimedia techniques will greatly alter the curriculum and the judgment The curriculum is not only the print books, but also the type of e-textbooks that have all the letters and channels
- Orientation for the innovation of the general education program: programs and textbooks in the direction of developing the capacity to positively impact the determination of educational objectives and the walls that illustrate those goals by the standard output described by the system of General forces and specialized competenability
- Renewal of high school teaching methodology: innovation of teaching methodology is making a move from the education program to access the
Trang 7content to the learning of the student, that is, from the place of interest to students learn something to the place of interest What the students are doing by learning
1.3 Application of IT for teaching and learning chemistry
IT which is applied in teaching and learning is very popular today as:
- Compiling lectures, electronic lessons
- Applying utility software in teaching and learning
1.4 ICT capacity of teachers and students
Many countries in the world have been implementing electronic education development projects Through the project, teachers are fostering technological knowledge In Vietnam, there have been many training facilities equipped with modern computer systems, many projects to build computer networks connecting education units on a nationwide scale are being deployed However, many units have not yet made the most of the ability of the information equipment to use in teaching to improve efficiency and innovation
1.5.2 Self-study
- Concept: self-study is a scientific solution that solves the conflict
between the massive amount of knowledge with a time-free fund while studying at the school Self-study helps to create sustainable knowledge for each person because it is the result of excitement, search, research and choice
- Role: student's self-study plays an important role in the request for
education and training innovation, improving training quality in schools The innovative teaching method in the direction of positive learning will promote positive, self-awareness, initiative and creativity of the students in the field of
Trang 8scientific knowledge Therefore, self-study is the path of development in accordance with the rules of evolution of humanity and is the right pedagogical measure that should be promoted in the high schools
- Skill: includes 3 groups of skills: self-study orientation skill Group; skill
groups performing self-learning activities; self-Test skill group, self-study assessment
- SSC: self-study is a process by which a person is able to perform
academic activities, may need or not need the support of others, predict their learning needs, identify learning objectives, detect resources, and people helping with the learning process, know the options and implement the learning strategy and evaluate the results of implementation
- SSC chemistry: chemistry can form, develop the students ' chemical
competency; thanks to the other subjects and the other educational activities,Chemistry gives a hand with forming, developing the principal qualities and the general capacity of the students, especially the world of science and interest; interest in learning, research; honesty; attitude respects to the laws of nature, behaves with nature in accordance with the requirements of sustainable development; the ability to choose a career that suits your competence and interests, conditions and circumstances
1.6 Teaching capacity development orientation
Educating the orientation of developing capacity to ensure the output quality of teaching, implementing the goal of comprehensive development of personality qualities, paying attention to applying knowledge in practical situations to prepare for Human resources solve situations of life and career This program emphasizes the role of learners as the subject of the cognitive process Thus, teaching the orientation of developmental orientation advocates helping learners not only memorize, memorize but also have to know how to do through specific activities, using the learned knowledge to solve situations due
to life sets out In other words, it must be associated with real life
1.7 Some methods of teaching the development of academic ability
In the scope of the thesis, we have analyzed a number of teaching methods for the development of students such as: teaching discovery and problem solving; teaching differentiation; using experiments in teaching; teaching under the project; WebQuest teaching methodology
Trang 91.8 The situation of using information technology to develop self-study capacity for students in high school
- The situation of the application of information technology: we
conducted survey on 76 chemistry teachers in domestic high schools The resulting figures are given some results:
+ The schools surveyed are mainly non-specialised public schools (reaching 3,9 points) and students with a major academic capacity (according to academic rating figures)
+ The school has a projector system, computer room is of good quality but the level of interest and encouragement to the application of IT of the secondary schools is still low average; and only rarely has seminar on application of IT in teaching been organized This is obviously a huge barrier to the faculty of teachers in exploiting and applying information technology to his teaching work
+ Most teachers have realised that the application of IT in teaching work is positive and necessary However the application of IT in teaching is not common and they only attend the training classes when required It can be seen that the application of IT in the teaching is the serious problem of the teachers themselves
+ The preparation of a teaching application of IT to the teacher is not easy
so that they should be well-appreciated for the lessons, which is the correct result for their efforts
However, the preparation of the teacher has almost stopped at composing, looking for information to show the students and focusing mainly on the teaching practice rather than being creative in the creation of teaching utensils
- The situation on the development of self-study capacity of students in schools: we have conducted surveys on 22 chemistry teachers and 237 students
in high school in the country The resulting figures are given some results:
+ 100% of both teachers and students believe that it is necessary for them
to maintain and develop SSC for students daily, and teachers have made efforts
to conduct SSC development for students in each lesson
+ While students ' study capacity is appreciated on average, the degree of completion of student self-study focuses primarily on the review and application of old knowledge and drastically reduced to the level of new knowledge
Trang 10+ The current resources are abundant but they are concentrated mainly in textbooks
+ The development of SSC of the students has been frequent but mainly also focused on reviewing and using the old knowledge in the study papers, textbooks and almost no self-study and use new knowledge
+ The process of delivery and check the student's work is conducted steadily in each lesson, and its content, however, its impact is almost exclusively focused on the study of old knowledge only
+ It can be seen that learning capacity is limited, self-study is not high, but students have realised the big impact of self-study to the content of the lessons
in the classroom They come to conclusion that the development of SSC of students needs to be deployed and developed regularly in every article, each learning content
Chapter 1 conclusion
We have an overview of the research situation in the world and in Viet Nam, systematize theoretical and practical issues which are the basis of capacity and SSC for high school students, investigation of the status of the application of IT and the development of self capacity school These are the basis for us to propose SSC structure for students as well as propose measures and procedures to develop this capacity for students
