Appendix (100 pages) CHAPTER THEORETICAL AND PRACTICAL BASIS ON CAPACITY DEVELOPMENT SELF-STUDY FOR STUDENTS AT HIGH SCHOOL 1.1 History of research issues on developing self-study capacity for high school students 1.1.1 Studies in the world Foreign research works have all confirmed the role of self-study in learners’ learning activities, which point out some basic self-study skills and note down the role of teachers in organizing teaching process to promote independence, selfawareness, creativity of learners, Through typical studies of self-study and selfstudy capacity from educators and psychologists in the world, we realize that selfstudy is a decisive factor for the life-long learning trend of every individual in this modern society The development of self-study capacity is extremely necessary, greatly and directly affects learners' learning while studying in high school as well as throughout their later lives 1.1.2 Domestic research works Thus, the issue of self-study and self-study capacity development for students has been mentioned in a number of books, research works and theses Most of the authors affirmed the important role of self-study in general and the development of self-study capacity for students in particular in improving the quality of learning, practicing the ability to think independently and increasing creativity in learners At the same time, the authors propose measures to improve the quality of self-study This is a valuable resource for us to continue in-depth study and to find solutions to develop self-study capacity for students in the process of teaching Chemistry at high school However, there has not been any specific research project on developing self-studying capacity for students through teaching Organic Chemistry at high schools, so we affirm that this is a new and valuable direction in terms of theoretical and practical aspects 1.2 Competence and self-study ability of high school students 1.2.1 Overview of capacity 1.2.1.1 Capacity concept In the thesis, we put forward the concept of competency as follows: “Capacity is the ability to mobilize knowledge, skills, attitudes and apply them appropriately to successfully carry out an activity in a certain context” 1.2.1.2 Structure of capacity 1.2.2.2 The purpose of capacity assessment 1.2.2.3 Several capacity assessment tools 1.2.3 Overview of self-study 1.2.3.1 Concept of self-study In summary, when summarizing the conception of self-study of the authors and in accordance with the research direction of the thesis, we give self-study this following direction: Self-study is being self-thinking, self-conscious, active, selfreliant and is to possess knowledge purpose, to form skills and learning attitudes 1.2.3.2 Forms of self-study 1.2.4 Self-studying ability of high school students 1.2.4.1 The concept of self-study capacity We define the research-oriented self-study capacity for the thesis as follows: Self-study capacity of high school students is the ability to plan self-study activities scientifically, and implement them effectively, then self-assess the achieved results and adjust the process with the support of teachers 1.2.4.2 The structure of self-study capacity 1.3 Some learning theories guide the development of self-study ability 1.3.1 Some basic learning theories guide self-study capacity development 1.3.1.1 Theory of operation 1.3.1.2 Cognitive theory 1.3.1.3 Constructivist theory 1.4 Some teaching methods and models of teaching methods which orientates the self-study capacity of students 1.4.1 Teaching method by contract 1.3.2.1 The concept of teaching by contract 1.3.2.2 Teaching process by contract 1.3.2.3 Advantages and limitations 1.4.2 Using self-study materials 1.4.2.1 Definition of self-study guide 1.4.2.2 Develop self-study guide 1.4.3 Blended learning model 1.4.3.1 The concept of "integrated teaching" 1.4.3.2 Combined teaching model 1.4.3.3 Moodle learning management system 1.5 Situation of self-studying and developing self-studying capacity for students in teaching Organic Chemistry in High School 1.5.1 Purpose of investigation 1.5.2 Investigated subject We conducted surveys at 19 high schools in the Central and Southern regions with the number of 131 high school teachers and 1150 students in grade 11 and grade 12 1.5.3 Content and method of investigation 1.5.3.1 Content of the investigation 1.5.3.2 Investigation method 1.5.4 Survey results 1.5.4.1 Survey results for teachers - The frequency of regular use of teaching methods and techniques towards developing self-study capacity in chemistry teaching - The frequency of using assessment tools in teaching chemistry - Organizational methods for students to self-study in teaching Chemistry (for teachers who use teaching methods to develop self-study capacity) - Teachers' awareness of self-study capacity in teaching Chemistry - The reality of students' self-study capacity is assessed by teachers 10 1.5.4.2 The survey results for students We used the questionnaire on students' self-study method in learning Chemistry and common difficulties of students during self-study process, specifically as follows: 1.5.5 General comment Most teachers realize that the development of self-study capacity for students is very necessary and important, but the use of positive teaching methods to develop selfstudy capacity for students is still limited Actual results stem from the following reasons: - The volume of Chemistry knowledge is quite huge added with new knowledge make it difficult to for teachers to teach due to the time constraint, so students have a lot of difficulties in learning Chemistry - Teachers still limit the use of positive teaching methods in the teaching process - Students still not have the habit of self-study as well as have any effective selfstudy methods Also, lack of guidance from teachers and self-study materials can make them feel difficult in self-study Thus, to overcome the current situation for teachers, it is necessary to think of some measures to develop self-study capacity effectively for students so they may not have any difficulty in the process of self-study This may also help them form and practice the habit of self-study and which contributes to improving the quality of teaching CONCLUSION OF CHAPTER Upon the overview of the research situation across the country and in the world, we realize that the development of self-study capacity in teaching chemistry for high school students is an important and urgent issue in meeting the needs of educational innovation and training as a whole Following that direction in chapter 1, we have studied the theoretical basis of developing self-study capacity for high school students and systemize some theoretical issues on: self-study, study capacity, self-study capacity, assessment of capacity, teaching methods and teaching models contributed to the development of self-study capacity for students We also conducted a survey on 131 teachers, 1150 students in grade 11 and grade 12 at 19 high schools in the central and southern region of Vietnam, which shows that the use of positive teaching methods to the development of self-studying capacity for students is still limited and students still have difficulty in self-studying Chemistry These are important theoretical and practical basis for us to propose the structure of self-study capacity as well as to take measures to develop self-study capacity for high school students in Chapter 13 this activity, students develop self-study capacity such as: - Capacity to set up a plan to conduct experiments: determine the objectives, methods, means and duration of experiment - Capacity to carry out experiments plan: prepare chemicals, tools and conduct experiments Observe, describe and make conclusion on solubility, color and odor of organic matter Or teachers can ask questions for students to relate the actual solubility, color, smell of some common substances in life For example: Question Question Do research experiments on solubility, color, smell of alkanes: Conduct experiment for ml of gasoline (including a mixture of saturated hydrocarbons) in 50 ml of water and add (g) lubricant in ml of gasoline From the results of the experiment, we can comment on whether the alkane solubility in water and whether alkanes can dissolve oil or fat Expression of self-study capacity Question - Capacity to develop self-study plans: + Determining goals and self-learning content: Test the solubility of gasoline in water and grease in gasoline + Identify testing methods and facilities: Take gasoline and lubricant at home or buy at the store Chemicals: gasoline, grease, water Tools: glass cup, stirring rod + Determining time for experiments - Capacity to implement self-study plan + Search information source: Prepare the above chemicals and tools + Analysis and information processing: Conduct experiments according to the instructions + Solve learning tasks: Observe, describe the phenomenon and draw conclusions about the solubility, color, smell of gasoline (5) Questions to guide self-study about the chemical properties of organic matter (6) Self-directed questionnaire on application and modulation c Designing a system of questions and chemical exercises to guide students in self-study and practice In the study, we designed a system of questions and chemical exercises to guide students in self-study exercises and review according to the learning contract 14 2.3.1.4 The process of organizing self-study activities according to the selfstudy guides From the structure of self-study capacity presented in Table 2.1 and studying the relationship between teaching and learning in organizing self-study activities of students, we propose the process of self-study activities in chemistry teaching Organic learning includes activities corresponding to the components of selfstudy component as shown in Picture 2.2 Activity Selfstudy planning Activity .Implement a self-study plan Activity Assess selfstudy results and adjust the selfstudy process TEACHERS Teachers give out self-study materials, use instructions and ask students to plan for selfstudy Hình STUDENTS Determine the content to self-study, methods, means and time of self-study Support students to implement the self-study plan with guidance materials Search, process information and apply knowledge and skills to solve learning tasks Organize learning activities in class: evaluate the results of self-study after using documents, supplement knowledge, correct troubleshooting and let students Report self-study results, ask questions, discuss and solve classroom learning tasks Self-assessment, adjustment and lessons learned 2.3.1.5 Use self-study materials guide to study new materials We designed self-study guide on Hydrocarbon included chapters with lessons to study new materials (9 periods) and practice exercises (4 periods) as follows: The 11th hydrocarbon portion Lesson Lesson 25 Ankan (2 periods) Chapter Saturated hydrocarbons Lesson 27 Practicing alkanes (2 periods) Lesson 29 Anken (2 periods) Chapter Unsaturated Lesson 30 Ankadien (1 periods) Lesson 32 Ankin (1 periods) hydrocarbons Lesson 33 Practicing Ankin (2 periods) Chapter Aromatic Lesson 35 Benzene and peers Some other 15 hydrocarbons Source of natural hydrocarbons Systematize on aromatic hydrocarbons (3 periods) hydrocarbons a Self-study guide and lesson plan in new material study lesson Example: Self-study guide and self-study activity lesson 25 Ankan We design experimental lesson plans as follows: -

The fact of developing self-study capacity for students in teaching Organic Chemistry at high schools is necessary, in accordance with the requirements of fundamental and comprehensive renovation of education that Resolution 29 has identified - The majority of teachers are not fully and exactly aware of the development of self-study capacity which is a strategic capacity for students in life-long learning 27 Therefore, the use of teaching methods to develop self-study capacity and assessment tools is very limited In addition, students not have the habit of self-study as well as having no effective self-study methods or lack of teacher guidance and self-study materials 1.2 From the results of theoretical and practical research, we propose the concept and structure of students' self-study capacity including component competencies and criteria, detailing levels corresponding to of these criteria This is the scientific basis of proposing a set of tools for evaluating self-study ability for students including: teacher evaluation form, teacher questionnaire, student selfevaluation sheet, test, and the foundation for us to propose two measures to develop self-study capacity for students is: Design and use of guidance materials for teaching Organic Chemistry of grade 11th in high schools; Design online courses on moodle system and apply Blended learning model in teaching We have designed Lesson Plans to illustrate methods to develop self-study ability 1.3 The content of the proposal was conducted on a pedagogical experiment in high schools in provinces/cities through experimental rounds with the participation of teachers and 712 students Collecting data from 4704 teacher questionnaires, 588 student self-evaluations and 1182 tests Qualitative and quantitative results have proved the feasibility and effectiveness of measures to develop self-study capacity for students in teaching Organic Chemistry in high schools, thereby confirming the correctness of Scientific hypotheses have been set The results of the thesis have achieved the goals: Developing self-study capacity for students through teaching Organic Chemistry at high schools, contributing to innovating teaching-oriented methods & directions based on learners’ capacity of the Ministry of Education and Training Recommendations For the Ministry of Education and Training: The research results of the topic should be continued to be applied and widely applied in teaching Chemistry at Vietnamese high schools For high schools: Schools need to pay attention, focus on developing selfstudying capacity for students in teaching Chemistry through applying: Contract teaching method, method design, self-study guide usage, online course design on moodle system and applying Blended learning model in teaching ...
