ABSTRACT
This study evaluated the effects of experiential teaching approach on pupils’ achievement in basic science and technology in selected primary schools in Onueke Education Zone of Ebonyi State. The study adopted a pretest post test, quasi experimental research design. Three research questions and three null hypotheses guided the study. A total of 426 pupils from 6 intact classes were used for the study. Three intact classes were assigned to treatment group while the other three intact classes were assigned to the control group. The treatment group was taught Basic Science and Technology (BST) using the experiential teaching method while control group was taught using the conventional teaching method. A basic Science and Technology Achievement Test (BSAT) developed by the researcher with spear man reliability co-efficient of 0.77 and internal consistency of 0.87 determined using the KR20 approach was used for data collection. and Analysis of Covariance (ANCOVA) to test the hypotheses. The research questions were answered using adjusted mean and standard deviations. The result revealed that there was a significant different between pupils taught basic science and technology using experiential teaching approach and those taught basic science and technology using the traditional (Conventional) teaching approach with experiential teaching approach being more facilitative. Again, there was no significant difference between male and female pupils taught basic science and technology using experiential teaching approach. Finally, it was found that there were no interaction effects between gender and methods on achievement in basic science and technology. It was therefore recommended among others that teachers of primary schools should adopt experiential teaching approach in teaching basic science and technology in the study area to ensure hands-on-activities and thereby contributing to enhanced achievement.

Simple machines |
At the end of the lesson pupils should be able to: Define simple machine (experience the activity |
Definition of simple machines. (a) makes work easier (b) increase the speed with which work is done (c) changes direction of force The facilitator asks some pupils to open a bottle with opener, and others to open without opener, cut a stick with knife or cut without knife etc. |
The pupils explain simple machines based on activities carried out or prior knowledge. This they do collaboratively as they work in groups. |
Explain classes of simple machines. |
There are three types of major classes of simple machines. But generally machines can be classified into simple and complex machines. But we want to concentrate here on classes of simple machines. Examples of simple machines are; spoon, fork, can opener, broom, harmer, cutlass, pliers, etc. hence simple machines can be classified into three main groups; first class, second class and third class simple machines. The simple machine machines are divided into three major parts: the load, the effort and the fulcrum (turning point). The classification of simple machines into those three classes is based on the position of the load, effort and fulcrum. |
The pupils work in groups, examine the different materials given by the facilitators, describe it and agree on a consensus opinion. The facilitators move round the groups and ask questions to guide the pupils. |
|
Give examples of simple machine |
Based on the instructional materials which were provided or supplied by pupils, they identify the following types of simple machines.
1. The lever: The lever has three Parts. – Fulcrum (b) the load (c) the efforts specific examples of lever include: the wheel barrow (b) the sugar tong (c) bar and wedge. The pulley: This is a machine used to lift heavy objects by applying a little force relative to the load. There are simple pulleys and movable pulleys etc. |
Pupil share the experiences, describe, results publicity, individual or by groups. |
|
(Process) mention the uses of simple machines. |
The facilitator will organize activities and – Opening of bottle cork such as fanta or coke e.g opener – driving nails into wood by carpenters e.g harmer. – Carrying load e.g barrow etc. |
Pupils describe the uses of simple machines based on activities carried out in the class |
|
(Generalize) state the advantages of using simple machines. |
The pupils should compare using simple machines with using bare hand and therefore find out that: It makes work easier It enables large work to be done It saves man’s energy etc. |
Based on the activities done by pupils they will provide the answers while teachers guide them. |
|
(Apply) mention places where machines are used to do work. |
– farmers use hoes to turn the soil before planting seeds. – Carpenters use harmer to drive nails into wood. – Children use broom to sweep classrooms. – Mothers use kitchen knife to cut vegetables at home |
Pupils relate what was learned to situations outside the classroom. |
|
Evaluation: |
Mention two examples of simple machines used at homes (2) How do we make our work to be easier? (3) Mention two types of first class machines used at your homes? |
||
Friction |
At the end of the lesson pupils should be able to: |
||
Define friction (experience the activity) |
Facilitator (teacher) arranges series of activity that will lead the learners (pupils) discover that friction is the force which makes moving things to slow down and stop moving. The force is important as it helps us walk without falling. It produces heat. It causes rubbing parts to wear out or get damaged. |
Pupils are provided with different instructional materials and directed on activities to perform by teacher, which will lead them to define friction. They may also define it based on prior knowledge. |
|
(share) mention the heat caused by friction |
Based on the simple activities which the facilitator (teacher) must have asked the pupils to perform, such as rubbing of their shoes on the ground the pupils will be able to state that: friction produces a lot of heat. When one rubs two palms together for some time they become hot etc. |
Children share to the entire class the group activity, from which they draw their conclusions. |
|
(Process) state the harmful effects of friction. |
Based on activities carried out by the various groups, they will mention that friction: wears off the sole of our shoes, sandals and slippers. – It wears off tyres of bicycles, cars and motorcycles. It also wears of metal surface such as knifes and make them blunt. It damages parts of machines etc. |
Teachers guide pupils through short structured questions while they work in groups to find out answers. Pupils give out the answer. |
|
(generalize) |
Facilitator through structured questions should guide the pupils to state that, whenever two surfaces rub together, it causes frictional forces which produces heat and wears away the materials, these damages the two object hence there is need to reduce such rubbing together. These can be done by: lubrication, application of oil or grease to two surfaces that move together. (b) Use of ball-bearing – A ball bearing is a round part of a machine that allows a moving part to turn against a fixed part smoothly. (c) Use of chain drive belt etc |
The pupils draw the generalization through the help of the teacher who guides them on what to do in their various groups |
|
(Apply) pupils state application of frictional force in real life. |
The pupils will be able to state that without frictional force man cannot walk. Mechanics apply grease to two car parts that rub together to reduce their wearing away due to frictional force. Kitchen knives wear out their surface because they rub together with object they are cutting etc. |
Teachers guide pupils through structured questions to mention situations outside schools where the effect of friction is felt. |
|
EVALUATION |
Why do your sandals wear off their soles? (2) Mention one advantage of frictional force. (3) How do we reduce the Frictional force between two parts of simple machine. |
||
Living and non-living objects |
At the end of the lesson pupils should be able to: |
||
Define living and non-living things (Experience the activity) |
Definition of living and non-living things. Based on activities carried out by pupils they will discover that living things are objects that are alive. There are two types of living thing animals and plants. They can grow, they can eat, they produce young ones, they die, they respond to changes in their surrounding. Examples of living things are teachers pupils, lizards, birds fish, mango trees, grasses in the field, goats etc. Non-living things on the other hand are things that are not alive. They do not do what living objectives do, such as eat, grow, respond to changes in the environment etc. examples are stone, woods, water, sand, cars, bicycles, chalkboard, table, pencil etc. |
Pupils are taken out of the classroom or are presented with some objects by the facilitators and are asked to carryout some activities designed by the facilitator. |
|
(share) differentiate living and non-living things |
Based on the activities carried out by the children in their different groups, they are able to state that, mango trees grow and bear fruits for example. It is a living thing. Other living things include: fish, dog, goat, teacher, pupils, parents etc. While non-living things, because they do not grow, eat, reproduce are non-living things e.g stone, table, biro, pencil etc. |
Pupils differentiate living and non-living things based on activities carried out in their various groups. |
|
(process) classify objects into living and non-living thing |
Pupils based on the activities carried out by them in the various groups are able to state categorically which objects can be classified as either living or non-living things. They also mention that living objects can become non living object. While non-living objects can not be a living objects. They are able to state those characters that make an object to be classified as living or non-living objects. |
Pupils classify objects into living and non-living. They also mention the characteristics of living and non-living things. |
|
Generalize |
Pupils are able to mention other objects outside the classroom and are either living or non-living objects. |
Pupils are able to generalize the knowledge learnt in the classroom to situations outside the classroom. |
|
(apply) Pupils are asked to mention objects in their homes, and communities and classify them into living and non-living things. |
Pupils carry out the task as directed by the facilitator (teacher) and were able to mention different objects in their homes and are able to classify them. Such objects include spoons, raw yam, boiled rice, tables, river, water, mosquito, termites, wooden gong etc. this stage enhances transfer of learning |
Pupils mention and classify these objects into living and non- living things. |
|
Evaluation : |
Mention three objects in your home that are living things. 2. Mention one characteristic of a non-living thing. 3. Mention two objects in your community that are non-living things? |

Define friction |
Definition of friction: This is the force which makes moving things slow down and stops moving. The force is important as it helps us to walk without falling. It produces heat. It cause rubbing parts to wearing out or get damaged. For instance the wearing out of our slippers or soles. |
The teacher explains this to the pupils. |
|
Mention Heat caused by friction |
Friction produces a lot of heat when a machine works for some time some of its parts become hot, because these parts are rubbing against each other |
The teacher explains this to the pupils while the pupils listen. |
|
State the harmful effects of friction |
(1) It wears off the soles of our shoes (2) it wears off the tyres of cars. (3) motorcycles and bicycles tyres (4) surfaces of machines wear out (5) it wears away kitchen knives and make it burnt |
The teacher lists these effects while the pupils listens attentively |
|
States ways to reduce friction |
Friction can be reduced by (1) Application of lubricants such as oil or grease. This is done to two surfaces that move against each other. 2. reducing friction with ball-bearing. A ball bearing is a round part of a machine that allows a moving part to turn against a fixed part smoothly. 3. reducing friction using a simple belt drive 4. reducing friction by chain drive etc. |
The teacher explains while the pupils listens and write down notes. |

Living and non-living objects |
At the end of the lesson. Pupils should be able to: |
||
Define living and non- living objects |
Living things are objects that are alive. There are two types of living things:- animals and plants. We know living things by what they do: (1) they can grow, they can move, they can eat, they produce young ones, they die and, they respond to changes in their surroundings e.g teacher, bird, lizard, fish, mango tree, grass, goat, mosquito etc Non-living things are things that are not alive. They cannot do what living objects do. Such as grow, etc, move around, reproduce, die, respond to changes in their environment etc. |
The teachers define living and non-living things and gives example. |
|
Differentiate living and non-ling things. |
The following are some example of living things: – mango trees, grasses, teachers, pupils, fathers and mothers, fish, dogs, cows, etc while the following are examples of non-living things: stones, water, black board, pencil, biro, kitchen knives, table, cloths etc. |
