Background

This Learners' Handbook contains information on Biology Integrated with Technology activities related to topics in the UCE Biology Curriculum. The practical activities in this Handbook provide an economical product or provide a service. Comparing it to a number of Biology textbooks, that have the conventional practical activities, most of which are done in school laboratories, do not directly relate to everyday life experiences.

Foreword

It should be appreciated that Science and Mathematics are key learning aspects that play a vital part in our lifestyle. At home, within a community, national and internationally learners meet with Science and Mathematics functional knowledge. Therefore, the need to broaden an understanding and skill development is of paramount importance for sustainable development. We find it easier to carry out scientific and Mathematics activities outside the classroom for example making garments, bread, alcohol, ice cream and furniture. All these activities are directly related to what is learnt in Sciences and Mathematics at school but no reference to them is done thus making these subjects abstract and less interesting. This is to appeal to the users of this book to avoid neglecting innovations that guide learning but embrace all the Science/ Mathematics concepts in the curriculum.

Preface

The major reason for undertaking this new approach to teachinglearning Sciences and Mathematics at O level is to improve the academic achievements and interest of learners. The idea of integrating Technology into Sciences and Mathematics at lower secondary education was conceived after realizing that Science and Mathematics teaching at this level hardly generated interest in the learners. In addition, these learners were lacking in practical skills and rarely applied Science and Mathematics to everyday life situations. The National Curriculum Development Centre (NCDC) has developed this new approach of teaching Science and Mathematics by including practical activities that enable learners to come up with products or be able to offer services to the community leading to national sustainable development by generating their own income.
