Unit: The Strategy of defense and treatment         Duration: 15 minutes
Topic: The different types of WBCs.


Objective

          The different types of white blood cells are described using power point presentation.

Content Summary

          Based on the presence or absence of granules WBCs are classified into granulocytes and agranulocytes. Granulocytes have large granules in the cytoplasm. This includes neutrophils, eosinophils and basophils. Agranulocytes donot have granules in the cytoplasm. This includes lymphocytes and monocytes.

          Neutrophil has several lobes and form 65% of WBC count. It is involved in phagocytosis. Eosinophils have two lobes in the nucleus. It forms 2-5% of WBC count. It is involved in allergic reactions. Basophils are least in number. It contains histamine.

          Lymphocytes are smallest WBC. Presence of large nuclei. Account for 25% of WBC count. It produces antibodies. Monocyte is the largest of WBC. Dark kidney shaped nucleus. Highly phagocytic cells.

INTRODUCTION

Kerala views education as a crucial path for shaping its future. To face the challenges of the present day world, we have to envision a progressive and comprehensive education system. However a close look at society indicates the existence of a section of people who have an intense desire to gain social and financial supremacy. Another group is striving hard to free itself from the clutches of poverty and procure the basic necessities of life.
    The Government of Kerala, after the formation of the state, set the direction for the educational system by declaring that the state would provide for:
§       Compulsory primary education for all.
§       Educational expenditure of all children.
§       Free text books and lunch for the needy.
 The policies followed by the successive governments in Kerala made formal education more accessible to its common folk. Some of the major initiatives taken include:
§       Providing text books at low prices.
§       Withdrawing tuition fee
§       Allowing concessional rate for student’s conveyance.
§       Providing free lunch in schools.
§       Ensuring at least one high school in every Panchayath.
§       Adopting new approach for promotions to higher classes.
§       Expanding vocational and technical education.
§       Taking steps for ensuring higher secondary education for all.
§       Bringing higher secondary within the fold of school education
§       Envisioning IT as a part of the curriculum.
§       Launching of EDUSAT and VICTERS channels.
§       Strengthening the school library system.

Quality education
                National Policy on Education- 1986 laid stress on universal enrolment and retention along with quality education. The following initiatives of central and state governments mark their commitment to provide quality education.
§       Launching Operation Blackboard scheme
§       Launching Special Orientation for Primary Teachers
§       Establishing State Council of Educational and training.
§       Setting up District Institutes of Educational and Training.
§       Establishing Colleges of Teacher education and Institute of Advanced Studies in Education.
        The curriculum reform was based on the vision of education as a social process. The methodology outlined by the curriculum stresses on activity based process oriented learning. It also stresses on enquiry based learning and liberal democratic learner- friendly approach that leads to the overall development of the learner. 
The aims of education in our society can be stated as:
§       Social justice
The education system that is envisaged should be capable of promoting a social order based on equality and justice.
§        Awareness on environment
We need to develop an attitude in our learners to see meaning in all developmental activities in tune with the environment.
§       Citizenship
There is a need for empowering each child to grow up and develop as a responsible citizen of the society.
§       Nationalism
Creating a generation upholding nationalism rooted in a Universal vision.
§       Awareness of one’s rights
Education needs to actualize the rights ensured in our constitution and also the rights enumerated in UN conventions on children’s rights, women’s rights.
§       Awareness of Science and Technology
All learners should get opportunity to acquire current developments in the fields of science and technology and apply the same in real life situations.
§       Scientific temper
There is a need to differentiate between science and pseudo science. Education should play a key role in freeing the society from superstitions and prejudices and should propagate the need for a scientific outlook the need for a scientific outlook in life.
§       Cultural identity
Regional and traditional forms of knowledge can be utilized for the development of the society.
§       Vocational skills
Education should focus on the development of a positive attitude to labour and inculcate in all children the ability to work.
§       Democratic values
Education should help the learner in imbibing democratic values.
§       Resistance
Strength to resist all sorts of invasions and desirable tendencies triggered by globalization.
§       Construction of knowledge
The process of education must develop in learners, the ability to construct knowledge through interaction and sharing.
§       Critical education
The education should have the space for learners to engage in critical dialogue. The educational system should prepare the learners to shift from the position of passive listeners to active constructors of knowledge.
Socially and culturally marginalized
General education must accommodate all children who are socially and culturally deprived.

Current issues
§       Non availability of schools within easy reach for tribal children.
§       Poverty remains a roadblock in educating such children.
§       Non availability of educational concessions on time.
§       Lack of a conductive home environment.
§       Inadequate facilities in institutions.
§       Lack of learning materials that suit the different languages of tribal groups.
§       Discriminations that prevail among them.
§       Superstitious practices that prevail among them.
§       Inferiority feeling arising out of the marginalized status.
§       Children being left alone at home as parents cannot adjust their working hours according to the school time.
§       Lack of awareness among parents regarding the emotional support to be accorded to children.
All these create hurdles in the educational progress of the marginalized.
Learning Science
        While handling over the wealth of science to the next generation, it is important that the following ideas are considered.
§       The process oriented method of learning helps the learner construct new forms of knowledge.
§       Concepts and ideas in science that the learner constructs should have linkage with real life situations.
§       Considering the nature of content, science is organized in terms physics, chemistry and biology.
§       The prevailing dichotomy of theory and practices needs to be replaced by creating opportunity to form theory based on practical experience.
§       The study of science in a competitive society should enable the learner to realize his/her identity.
§       Science education should aim at equipping the learner against the misuse of science.

Awareness of science
        It accounts for:
§       The ability to observe things in a minute and perfect manner without prejudice.
§       The skill to measure and document a piece of sample information.
§       The ability to analyze and interpret data.
§       The skill to arrive at certain conclusions according to the data collected.
§       Approval of the right to question and to be questioned.
§       Insistence on decision making according to the evidence gathered.
§       The readiness to reexamine the conclusions.
§       The ability to identify what is unscientific.
§       Broadmindedness.
§       A respect for the right of others to take a different stance.
§       The commitment towards logical reasoning and factual enquiry.

Major criticisms
§       There is a notion that the aim of science education is to transmit knowledge that has already been gathered.
§       The learning process is neither process oriented nor learner centered thus the learners do not have the opportunity to engage in learning activities and construct knowledge.
§       There is a tendency to promote rote learning of concepts in science to excel in examination.
§       The innate curiosity and scientific temperament of the learner are yet to find space.
§       Examination centric text books and learning process.
§       Incongruence between the content and the level of the learner.
§        Scientific temperament and literacy are not addressed adequately.
§       Learning of science fails to become interesting and challenging to the learner.
§       Construction of knowledge has not been duly recognized.
§       Science education has yet to become life related.
§       Mechanisms for empowering learners in the pedagogic practices are yet to be strengthened.
§       The assessment of effectiveness of teaching science is completely neglected.

IT Assisted Education
            The present status of IT education in high schools in Kerala helps only to develop certain fundamental IT skills. The learning process of different subjects can make use of IT to make learning effective and meaningful. IT can also help in teacher empowerment.

Social Issues

§       Lack of scientific land water management.
§       Issues related to agriculture
§       Lack of cohesive universal vision.
§       Lack of human resource development.
§       Lack of cultural consciousness
§       Lack of eco friendly industrialization & urbanization.
§       The issues of the marginalized.
§       Issues related to health and public health.

                                          CONCLUSION

        Based on the National Curriculum Framework 2005, efforts to revise the Kerala School Curriculum began in August, 2006. The first phase of the revision process is culminated by the publication of the Kerala Curriculum Framework 2007. The process of curriculum framing is envisioned in a democratic manner. Large scale action programmes that are related to the development of Kerala have been designed.
        Kerala could display the active working model of a learning process that has its foundation in the principles of Constructivism and a learner-centered, activity-based and process-oriented pedagogy. The curriculum that has been designed, along with the learning materials prepared, has much to claim on the grounds of quality.
