LIFE AND EARTH SCIENCES CURRICULUM - INTERMEDIATE LEVEL

INTRODUCTION

The beginning of the twenty first century witnesses a considerable progress in science and technology, as well as, their applications to man's service. This progress, thus, requires the necessity of a new orientation of teaching in response to the needs of the contemporary world. For this reason, a curriculum of clearly defined objectives, updated knowledge, new teaching methods and approaches, and varied evaluation techniques, is a primary concern of education.

The program tends to establish a relationship between technology and society with which the student has strong ties. Moreover, the program deals with a global perspective about health and the environment. This helps the student to maintain his health and the health of others, to develop a responsible behavior towards the environment, and to comprehend scientific messages transmitted by media.

By focusing on teaching scientific processes, the student becomes an active participant in a problem situation. Further, it allows the learner to acquire skills of: scientific reasoning, communication, observation and experimentation techniques, and transferring prior knowledge to new situations.

The curriculum clearly defines methodological, technical, and cognitive objectives. The latter, is selected and developed according to a vertical and a progressive coherence. The focus is on considering the students' background in order to meet their needs. The use of different approaches encourages them to construct their knowledge themselves. In this perspective, it is emphasized that evaluation must not be limited to recalled information but should also assess the skills required to be achieved.

The curriculum fosters the development of autonomy and responsibility of personal behavior in learners that are characteristics of a free citizen.

 

OBJECTIVES

The actual progress of biology and its fundamental knowledge, as well as, the technology of life, and their applications for man's service requires a new orientation of teaching at the intermediate level to cope with the contemporary world requirements. Such teaching should:

-        Reinforce and complete what has been acquired previously at the primary level.

-        Provide students with a scientific culture necessary to help them in continuing their studies at the secondary level, or to be vocationally oriented.

-        Permit students to acquire scientific processes, specifically by developing an experimental approach and problem solving activities.

-        Develop in students a scientific attitude and motivate them to acquire a better autonomy.

-        Encourage students to appreciate the role of empirical proofs and models in science as well as to consider and accept uncertainties of explanations and interpretations related to the observed phenomena.

-        Permit students to conduct scientific messages; make scientific arguments; master the techniques of observation, experimentation, and analysis; and acquire scientific accuracy and critical thinking.

-        Develop a sensibility towards bioethical issues.

-        Initiate in students progressively and continually a scientific knowledge, technical performances and actual research in science and technology.

-        Permit students to have tolerance and intellectual honesty while dealing with social, cultural, and environmental problems of the contemporary world.

-        Permit the student to identify integrated domains within different disciplines and be able to transfer them to different fields.

-        Allow the students to aquire a package of scientific knowledge necessary for the comprehension of the contemporary world and its changes with respect to life and environmental resources. This knowledge corresponds to fundamental notions emerging from biological and geological concepts covered at the intermediate level: behavior, nutrition and metabolism, biological renewal, reproduction and genetics, interdependence of living things, and dynamics of the earth.

-        Foster in students the understanding of the most common manifestations of the human functioning and adopting a behavioral attitude towards hygiene and prevention according to aquired knowledge.

-        Allow the student to identify the essential biological, physical, and geological components of the environment and to understand their relations that initiate the development of an open and a responsible behavior toward environmental problems: management of media and resources, preservation of species, and risk prevention.

-        Make the student aware of the organization of the living world, its unity and diversity.

 

CONTENTS:

Grade Seven

1)      Nutrition

This part deals with the behavioral aspects of animals related to how they recognize, obtain and consume their food.

The study about food consumption is limited to the transformation of food into nutrients that can be utilized by the organism.

The organic matter produced by chlorophyllic plants or consumed by non-chlorophyllic plants and animals is used for body construction.

The study of transfer of matter between the producers, consumers and decomposers will be the first entry to provoke the students' sensibilities toward the environment.

§   Relation between environmental conditions, body activities, and nutrition

-        Relationships between food energy and body activity requirements.

-        From passive to active life : hibernation and germination.

 

§   Nutrition and respiration: vital requirements

-        Importance of nutrition and respiration at the level of the organism.

-        Importance of nutrition and respiration at the level of the habitat.

 

2)      Reproduction

This part clarifies the significance of sexual reproduction in contrast to vegetative reproduction.

The study of different modes of sexual reproduction in animals is exposed in a behavioral way.

§   Animal reproduction

-        Courtship in animals during sexual reproduction.

-        Fertilization

-        Development

3)      Inter-relationships between living things

This part deals with the relationships between living things and the influence of environmental factors.

The study of food webs leads to the concept of transformation and cycling of matter.

The multiple applications of productivity (agriculture, animal raising) focuses on Man‘s responsabilities towards the management of dynamic equilibrium in nature.
