ASSIGNMENT

1                     TEACHING METHODS IN TEACHING SCIENCE.

2                     LESSON PLAN IN TEACHING SCIENCE.

ANSWERS

1.     Lecture Method: This is the oldest method that has been used by the teachers to teach almost all the subjects of the curriculum at all grades and levels. It belongs to the category of autocratic strategy as the teacher plays a virtually the role of a monarch and autocrat, controlling each and every function of the classroom teaching. In simple meaning, this strategy may be defined as a mode or planned scheme devised and employed by the teacher for presenting a segment  or unit of the desired content material of a subject to a group of learners through  lecturing (verbal communication of ideas) aiming to attain specific teaching-learning objectives related particularly to the cognitive and affective domain of the learners behavior.

Advantages of Lecture Method

·        It provides a long rope to the teacher for controlling and monitoring the teaching-learning activities of the classroom by remaining the pivot of the teaching-learning process

·        It can help to realize not only the lower cognitive objects like information and development of understanding but also to attain higher cognitive objects like power of analysis, synthesis evaluation, reflective thinking.

·        It may provide experiences that inspire and its useful for large groups.

·        It is the most effective way to convey teacher spoken information.

Disadvantages of Lecture Methed

·        Proficient oral skills are not necessary.

·        The audiences are often put under pressure.

·        Learning is difficult to determine as the lecture progresses.

·        It is not appropriate for all level of learners.

2.     Group Discussion Method: This term refers to a discussion by a certain group of learners in the level for a specific instruction. The group discussion as a method of teaching science is defined as some sort of discussion i.e interchanging of ideas between students and teacher or among a group of students resulting into active learning for the realization of the predetermined teaching-learning objectives. This group discussion, in no way, occurs occasionally or incidentally but is planned and organized with deliberate efforts on the parts of the teacher and students for achieving the set goal.

Advantages of Group Discussion

·        It ensures active participation by the learners.

·        It trains the learners to carry out tasks in groups i.e team work.

·        It provides opportunities for the learners to be good listeners and good team leaders.

·        It enables the learners to be rational in nature.

Disadvantages of Group Discussion

·        It requires proper guidance by the teacher so the learners would not go out of track.

·        It may lead to conflict of interest by the learners

·        The shy learners would not want to contribute.

·        It may be dominated by some set of learners.

Other Methods of teaching science includes

ü Demonstration Method

ü Discovery or Heuristic Method

ü Project Method

ü Problem Solving Method

ü Question and Answering Method

ü Role-Play Method

ü Case-Study Method

ü Direct Teaching Method

ü Collaborative Method

ü Lecture Method

Question 2 lesson plan in science

OUTLINE OF LESSON

NAME OF TEACHER: OLOWOOKERE BUKOLA ROSE

NAME OF SCHOOL: FEDERAL SCIENCE AND TECHNICAL COLLEGE

YABA

CLASS: JSS2

SUBJECT: BASIC SCIENCE

TOPIC: CHANGES IN MATTER

PLAN FOR JUNIOR SECONDARY SCHOOL 2

PERIOD: 1 (1.40 -2.20 p.m)

DATE: 7/6/2014

BEHAVIOURAL OBJECTIVES: At the end of the lesson, students should be able to

1.     Define matter, give states of matter

2.     Observe and Group the changes in matter

3.     List 4 causes of change in matter

PREVIOUS KNOWLEDGE: students have been taught “Matter” in their previous class JSS1

PRESENTATION: the teacher presents the lesson by the following step;

INTRODUCTION: the teacher introduces his lesson by asking questions to confirm the level of students’ knowledge of the previous lesson and he introduces his new topic

STEP I: the teacher explains the concept of changes in matter

STEP II: the teacher gives states of matter with examples of each state

STEP III: the teacher gives the types of changes that occurs in matter with examples

STEP IV: The teacher gives the cause of change

INSTRUCTIONAL MATERIALS: Realia (desk, bag,  building etc)

INSTRUCTIONAL CONTENT:

Matter is anything in nature that has weight and occupies space. There are three states of matter namely, liquid, solid and gaseous. Matter can change from one state to another depending on which state it is subjected to a change, and the factors to which the matter is exposed.

Types of changes in matter

Changes in matter can be temporary (physical) or permanent (chemical) . the table below gives the differences between the change in matter

Sn

Temporary change

Permanent change

1

It is reversible

It is not reversible

2

The composition of the matter is not changed

The composition of matter is changed

3

It is also called physical change

It is also called chemical change

4

It does not involve any great heat to change

It requires great heat to change

Examples of changes in temporary and permanent changes

Sn

Temporary change

Permanent change

1

Freezing of water

Burning of wood

2

Melting of candle wax

Rusting of iron

3

Dissolving of sugar in water

Yellowing of leaves of plants

4

Mixing kerosene with water

Burning of chemical in air

Causes of Changes in Matter

For a change to occur in matter there must be causes. The cause occurs as a result of an alteration or a change in the environmental condition around the matter. There are many factors that can also affect the change in matter. They are

·        Temperature

·        Pressure

·        Light

·        Air and water (moisture)

·        Chemicals

·        Electricity

CLASS ACTIVITY: students and the teacher participated in class discussion.

EVALUATION:

1.     What is matter

2.     State two changes that matter?

3.     List three differences between temporary and permanent changes.

4.     Give two factors that affect the changes in matter

SUMMARY: the teacher summarizes the lesson by going through the main points of the lesson again

CONCLUSION: the teacher concludes the lesson and gives note of lesson to the students.

ASSIGNMENT: list and explain 2 types of physical changes.
