1 REASONS FOR CHOOSING THE TOPIC
The world is entering the 21st century, the century of a rushing development of science and technology The Knowledge economy requires education sector to innovate to meet the need of training human resources, which is in line with the development of the society In the comprehensive education reforming progress, reforming teaching methods receives significant decisions in all subjects and grade levels One of these is applying active teaching methods, which have been the world's advanced practices, to the case of Vietnam Those are the modern learner–centered teaching methods to promote awareness capability, independent creative ability to detect and solve the problem of the learners
Project–based Learning (PBL) is a modern teaching method, fully meets the requirements that need advanced education, in accordance with Article 28.2 of the Education Law of Vietnam and can be applied in our schools in the present conditions
In Vietnam, Intel Vietnam and the Ministry of Education and Training of Vietnam officially put PBL into implementation in high schools from 6 December, 2005 Vietnam – Belgian Project had been launched in 4.5 years from 2004 to 2009 in 14 northern mountainous provinces
Chemistry subject has links with other science subjects such as Biology, Geography, Physics, so the application of chemical knowledge is very rich
in life, involving many sectors of society These are favorable conditions for the application of PBL through the integration of knowledge of this subject However, at present, the application of PBL in teaching chemistry at high school has not been commensurate with its importance So far there is no deep research on systems theory and application of PBL in general chemistry published
For the reasons above, we choose and study the topic: “Applying the
project-based learning in teaching inorganic chemistry in high school” for

Chapter 1 THEORETICAL AND PRACTICAL BASIS
OF APPLYING PROJECT-BASED LEARNING
IN TEACHING CHEMISTRY HIGH SCHOOL
1.1 LITERATURE REVIEW
1.1.1 The project–based learning in the world (1)
Derived from Europe but PBL is a genuine product of the progressive education movement America William Heard Kilpatrick is the first detailed description this approach in the article “Project method” (1918) PBL can be divided into five major periods: 1590 – 1765 (The beginnings of project work
at architectural schools in Europe), 1765 – 1880 (The project as a regular teaching method and its transplantation to America), 1880 – 1915 (Work on projects in manual training and in general public schools), 1915 – 1965 (Redefinition of the project method and its transplantation from America back to Europe), 1965 – today (Rediscovery of the project idea and the third wave of its international dissemination)
Nowadays, PBL is very common in use in all levels of education in developed countries of the world, in many different subjects
1.1.2 The project–based learning in Vietnam
(1) Knoll, M (1997) The project method: Its vocational education origin and international development Journal of Industrial
Teacher Education, 34(3), 59 – 80
Trang 4In Vietnam, PBL has been used in technical colleges and universities via students’ graduation thesis Through the Vietnam – Belgian Project, Intel Program and Universities of Education, PBL has come to teachers and pupils
in secondary schools, but high school students do not have access to PBL and PBL is also considered as a new teaching method
The academic research on PBL has included several authors mentioned in some articles and books such as Nguyen Van Cuong, Nguyen Thi Dieu Thao, Tran Viet Cuong, Do Huong Tra, Nguyen Lang Binh, Pham Thi Phu, Nguyen Thi Huong, Tran Van Thanh, However, researches applied PBL in each subject is still limited, particularly in chemistry Some graduation thesis, master thesis, doctoral thesis and papers on applying PBL in Chemistry from
2008 up to now has only been generally and modestly carried out on this particular issue
1.2 TRENDS OF INNOVATING TEACHING METHODS
1.2.1 The need for innovating teaching methods
1.2.2 Trends of innovating teaching methods in Vietnam
1.2.3 Innovations of teaching methods in teaching chemistry at high schools
To innovate teaching methods in Chemistry, teachers need to:
– Use the positive factors in recent chemistry teaching methods
– Select some perspective and positive approachs in modern education in several developed countries
– Select methods that promote students' positivities and are suitable to the objectives and contents of each certain chemical lesson, specific students and conditions of each region and locality
– Coordinate reasonably different teaching methods and modern teaching facilities
1.2.4 Orientation innovative methods of teaching and learning (1)
The two core factors of the innovation–oriented method of teaching and learning in a positive way are: a sense of comfort and active participation of students
1.3 ACTIVE TEACHING – LEARNING
1.3.1 Positiveness (2)
Positiveness is an inherent quality in human social life Forming and developing positiveness are one of the major tasks of education Positive

Chemistry, Vietnam – Belgium Project
Trang 5learning is closely related to independent thinking Thinking and independence are the seeds of creativity, thereby develop self–awareness, foster the excitement and motivation to learn
1.3.2 Active teaching methods in teaching chemistry
1.3.2.1 The concept of active teaching methods
Active teaching methods in teaching chemistry are holding learning activities to develop learners' creative ability, problem solving ability and through the operation of the school, to dominate the knowledge and build qualities of workers The teacher plays the role of a facilitator, who guides students and coaches learning activities efficiently
1.3.2.2 Features of active teaching methods in teaching chemistry
1.4 PROJECT–BASED LEARNING – AN ACTIVE TEACHING METHOD The term “project” is derived from Latin, means a proposal, a draft or a plan which should be implemented to achieve its goals In education, in the early
20th century, American educators had developed the theoretical basis for PBL and considered this approach to be important to point out “student–centered” Today, PBL is widely used in schools and universities around the world,
particularly in developed countries
1.4.1 The concept of project–based learning
PBL provides complex tasks based on challenging questions or problems that involve the students' problem solving, making decision, investigative skills, and reflection that include teacher’s facilitation, but not direction Group is the basic form of PBL work
1.4.2 Classification learning project
There are many ways of classifying learning projects, such as: subject, learner participation, the involvement of teachers, timescale, and tasks
1.4.3 Scientific basis of project–based learning
1.4.3.1 Center physiological characteristics of high school students
High school students’age belong to a common of period 15 – 18 years old, they have achieved a mature physical development and high–level thinking, have a role in family life and society; the growth has been driven career in their own future
1.4.3.2 Philosophical basis of project–based learning (1)
According to John Dewey (U.S.), philosophical foundations of PBL is the unity between theory and practice, thought and action, sensory perception and cognitive rationality and the rule received Lenin's formula
(1)Dewey, J (1933), How we think: A restatement of the relation of reflective thinking to the educative process
The later works of John Dewey (Vol 8) Carbondale: Southern Illinois University Press, pp 105 –352.
Trang 61.4.3.3 The school's educational basis of project–based learning
PBL is in accordance with the opinion of tectonic theory and interactional pedagogic
1.4.3.4 Psychological basis of project–based learning
Based on activity theory, PBL is with primary thesis “Human psychology
is formated and revealed through operation”, and based on the theory of tectonic perspective “through self–action, students can self–absorb and create knowledge”
1.4.3.5 Differentiated viewpoint in project–based learning
Differentiated teaching is a teaching philosophy, allows teachers to design lessons that appropriate to the needs, capacities, different learning styles of each student in the class to make all students become interested in learning and achieve the highest efficiency
Differentiated teaching is primarily in PBL at the micro level, centered on student's excitement and capability
1.4.4 Characteristics of project–based teaching
– Real world orientation – Orientation for learner's interest – Action orientation – Multiple presentation
– Flexible skills orientation – Learner's self–studying
– Complex tasks – Collaboration
1.4.5 Framework
– According to the documentation (1), PBL process consists of 6 steps: + Step 1 Choosing project work topic
+ Step 2 Scheduling
+ Step 3 Gathering information
+ Step 4 Processing Information
+ Step 5 Demonstrating
+ Step 6 Assessing results
Generally, three phases can be suggested in conducting PBL: planning, creating and implementing, and processing
– This thesis chooses PBL process in 5 steps by Dr Do Huong Tra
1 Choosing project work topic
Teacher facilitates student to propose project ideas, make themes
decisions, define objectives

1.4.6 Assessment learning outcomes in project–based learning
Assessment of student learning outcomes in PBL consists of knowledge, skills (through knowledge tests), competency assessment and students' attitudes during project implementation (through the checklist, observation),
at various times and combined evaluation of teachers and students, by the designed specific tools, including: a) observation checklist implementation process project, b) project monitoring book (Book of PBL), c) checklist evaluation study, d) attitude scale
1.4.7 Advantages and challenges of project–based learning
1.4.7.1 Advantages
* Learners: – Encouraged learning interest
– Combined theory and practical learning
– Promoting self–reliance, responsibility, creativity
– Increased problem–solving ability
– Increased collaboration and communication skills
– Increased persistence, patience
– Improved media research skills
– Improved assess skills
– Encouraged friendship
* Teachers: – Improved assess skills (observation, questioning):
assessment for learning, in learning and results
– Concerned and engaged student's potential
– Improved media research skills
– Increased knowledge and studying
Trang 81.4.7.2 Challenges
– PBL cannot be applied to all lessons
– PBL is a form of supplement to the traditional teaching methods, not a substitution for the oral and practice method
– PBL often takes longer than usual
– Classroom management: In order for students to work productively, teachers must balance the need to allow students to work on their own with the need to maintain order (1)
– Teachers have difficulty in designing assessments that require students to demonstrate their understanding
– PBL requires physical media and financial, especially needs the help of
IT, software applications and the Internet, the modern technical media (multimedia)
1.4.8 Conditions for project–based learning in chemistry education in efficiency
– Define clearly learning goals: What knowledge, skills, attitudes learners gain through projects Science and practical aspects are concerned in both chemistry and complex projects
– Content and topic of project must be associated with real life that relate
to lessons
– Other student characteristic variables include age, sex, demographic characteristics, ability must be paid attention to in order to promote individuals
– Teacher, school and family must create a friendly, positive environment, support and assist the physical conditions (technical means of information technology, Internet) and mental, time for new learning methods of students (learner–centered environment)
– Teachers must develop innovative assessments and always act as facilitators – Teachers need formating and training of higher–level thinkings and the skills required as good mirrors
1.5 SOME ACTIVE TEACHING TECHNIQUES TO SUPPORT PROJECT–BASED LEARNING
Include the followings: Group learning, Technique tablecloth, Mindmap, 5W1H questioning; Using some software, Internet, interview skills, using the camera, filming, setting the table, chart, comparing and contrasting, presentations, roling plays

Trang 91.6 THE REALITY OF USING PROJECT–BASED LEARNING IN TEACHING HIGH SCHOOL CHEMISTRY NOWADAYS
1.6.1 The survey conducted on teachers
Survey in 185 teachers of 51 provinces, conducted 3 times, from 8/2010 to 8/2012 showed that:
– These teachers in survey all have university degree (69.73%) and postgraduate (25.95%) Almost all of them are at the age of qualified good information technology and it is convenient to apply modern teaching methods using information technology: 35.14% of them over 5 year work, 50.27% of 10 – 20 years and 11.89% over 20 years of experience
– 71.35% teachers have understood and applied PBL, but not often
– 80.77% teachers said projects make learners be excited and very interested in 28.65% teachers still have not known about PBL, more than half of them (16.98%) are 20–year experienced teachers 98.92% teachers have desired to learn and apply PBL in teaching chemistry in high schools From the resulted show should continue broadly popular PBL for teachers and students
1.6.2 The survey conducted on students
The survey on 331 students, 35 teachers of 5 high schools in Hanoi city and Hai Duong province from 2009 to 2012 shows the results as follows:
– Awareness of PBL: 100% of students did not know about PBL
– Some skills needed to apply PBL in learning: those skills were still weak and lacking, shown in both teachers and students' self–assessment
– Students's attitudes: Awareness of the importance of chemistry with the life is low (18.95%), awareness of the right and responsibility to people and the environment is not full (21.02%) The relationships between the members
of the class are local (35.39% “good") They have no self–discipline, no initiative, positive learning and action (39.07%) Ratio of loving–chemistry students is small (14.88%)
– Students's innovative capabilities: They have limited chances to present creative capabilities in subject in general and chemistry in particular
