Teaching Secondary Mathematics Textbook

On Friday, September 25, , Nigeria unfolded the draft document of Vision The document anchored on two principal targets that will be achieved by the year The targets are: As we face global planetary, social and economic issues it falls on science and technology education to stand to the test of time in appreciating what has come to be their responsibility. Our society, therefore, depends on its science and technology education program for sustainable development.

Chemistry is one of the courses that are central to studies in science and technology. Chemistry is a branch of science that deals with the scientific study of the composition, properties and reactions chemical behaviours of chemical elements and their compounds. Its importance in technological development cannot be over emphasized. Chemistry was among the three basic sciences introduced into the secondary schools by the colonial government.

It is taught at the post basic level of education while at the basic level classes they had general science, which was renamed integrated science and then basic sciences with the emergence of the millennium goals. Credit level pass in chemistry at the ordinary level certificate examination is a requisite for subsequent specialist studies in pure chemistry, chemistry Education, Biochemistry, medicine, zoology, Botany, Geology, and other vocationally oriented programmes such as industrial chemistry, Pharmacy, Agricultural science, Engineering and Metallurgy.

Considering the indispensability of chemistry in technological development, one would expect a better performance and interest of students in the subject. Surprisingly available reports WAEC, ; Udo reveal that the performance of the Nigerian secondary school students in chemistry is dwindling.

Textbooks stand out at the heart of educational enterprises.

The Free High School Science Texts:

Teachers rely on them to set the parameters of instruction and to impart basic educational content. Textbooks constitute the base of knowledge, particularly in the third world countries where there is a chronic shortage of qualified teachers, and online educational services Naiz, Since textbooks are very important in teaching and learning processes, they need to be critically evaluated to see whether they are meeting the expected goals of the National policy on Education FRN, or that of the National policy on science and Technology.

In Nigeria today, there are many chemistry textbooks written by different authors, published and pushed into the market and schools. In Nigeria, the following chemistry textbooks were recommended by the ministries of education for the post basic level: New school chemistry for senior secondary schools students by Osei Yam Ababio ii.

Senior secondary chemistry BK3 by S. Bajah iii. Chemistry for senior secondary school certificate by V. Oyeyiola iv. Pure chemistry for west African schools by B. Oluba, B. A New Certificate Chemistry By Holderness and Lambert The fact is that these textbooks were never properly evaluated by specialists before recommending them for use in schools.

Consequently, the students may find them counterproductive with the devastating consequences of loss of interest and mass failure in chemistry examinations. There is, therefore an urgent need to evaluate the chemistry textbooks in use in our secondary schools, to determine their appropriateness so as to provide the basis and guides for their revision.

Objectives of the Study The major purpose of this study is to evaluate chemistry textbooks in use in secondary schools in Nigeria.

Specifically this study: Determined the adequacy of the content of the chemistry textbooks in use in the secondary schools 2. Determined adequacy of the learning activities of each of the chemistry textbooks in use in the senior secondary schools.

Determined the appropriateness of the study questions in each of the textbooks. Examined the readability levels of the textbooks. Assessed the population under-representation index of the chemistry textbooks.

Assessed the teacher perception index of the textbooks Research Questions The following research questions guided the study: How do the contents of chemistry textbooks in use in Nigerian secondary schools reflect the content specified in the core-curriculum? How adequate are the learning activities of the chemistry textbooks in use in Nigerian secondary schools?

How appropriate are the chapter summaries of the chemistry textbooks in use in Nigerian secondary schools? How adequate are the study questions of the chemistry textbooks in use in Nigerian secondary schools? What is the illustration index of the chemistry textbooks in use in Nigerian secondary schools? What are the readability indices of the chemistry textbooks in use in Nigeria secondary schools? What is the under representation population index of the chemistry textbooks in use in Nigerian secondary schools?

What is the teacher perception index of the chemistry textbooks in use in Nigerian secondary schools? Method This study employed the naturalistic evaluation design which according to wolf is the act of gathering information and juxtaposing it with some set of criteria to make judgment regarding the strength and weakness, merits or worth of an educational innovation, materials, programmes or products.

The researchers found this design useful because it involves making value judgment about chemistry textbooks in use in secondary schools in Nigeria. The instrument that was used for data collection is the 8 — point quantitative evaluation model for science textbooks. It was developed by Emerole in The 8-point model evaluates science textbooks using the following indices: Topical coverage Index TCI ii.

Learning activities index LAI iii. Study questions index SQI iv. Illustration index ILI v. Chapter summary index CSI vi. Under — representation population index UPI vi. Readability and comprehensibility index RCI viii. This was necessary because the researchers used five chemistry teachers in the evaluation exercise. A concordance of 0.

Results The results of the study are presented in the tables in line with the research questions that guided this study.

Research Question 1 How do the contents of chemistry textbooks in use in Nigerian Secondary Schools reflect the content specified of the core curriculum? Based on the data collected from the textbooks the ITC index of topical coverage was determined as presented in Table 1.

In the table Tt represents Number of topics sufficiently covered by the textbook, Ts is number of topics specified in the syllabus, St is number of subtopics sufficiently covered by the text while Ss is number of subtopics in the syllabus.

Table 1: Bajah et al 3 Chemistry for senior secondary 70 89 88 0. Oyeyiola et al 4 Pure chemistry for west African 67 96 90 0. C et al 5 A New Certificate Chemistry 7th 90 98 0. It is however necessary to note that Chemistry for senior secondary school certificate by V.

Oyeyiola and Pure chemistry for west African schools by B.

Oluba fall below the baseline. Bajah was adjudged to have attained minimum standard, there is a serious need for upgrade of the text. Research Question 2 How adequate are the learning activities of the chemistry textbooks in use in Nigeria Secondary Schools? Based on the data obtained from the textbooks, the learning activity index LAI was calculated and presented in Table 2.

Note that A represents number of sentences requiring the learner to perform some activity while P is number of sentences requiring the learner only to receive information with no other activity.

Table 2: Bajah et al 30 0. This implies that none of the five chemistry textbooks contained learning activities as specified in the core — chemistry curriculum. Research Question 3 How appropriate are the chapter summaries of the chemistry textbooks in use in Nigeria Secondary Schools?

In Table 3 Js is number of statements in the summary which re-present major points covered in the chapter, Jc is number of major points covered in the chapter, Ns is number of statements in the summary which re-present minor points covered in the chapter while Nc is number of minor points covered in the chapter Table 3: The results reveal that all the five chemistry textbooks evaluated are within the acceptance range of chapter summary. Research Question 4 How adequate are the study questions of the chemistry textbooks in use in Nigeria Secondary Schools?

The data obtained from the textbooks were used for the computation of the study questions index SQI. As you can imagine, having different units in use from place to place makes scientific communication very difficult.

This was the motivation for adopting a set of internationally agreed upon units. Natural Units This is the most sophisticated choice of units. Here the most fundamental discovered quantities such as the speed of light are set equal to 1. The argument for this choice is that all other quantities should be built from these fundamental units.

This system of units is used in high energy physics and quantum mechanics. The exception to this rule is if the unit is named after a person, then the symbol is a capital letter.

For example, the kelvin was named after Lord Kelvin and its symbol is K. If the abbreviation of the unit that is named after a person has two letters, the second letter is lowercase, for example Hz for hertz.

Exercise: Naming of Units For the following symbols of units that you will come across later in this book, write whether you think the unit is named after a person or not.

J joule 5. C coulomb 2.

N newton 7. UNITS 2. Table 2. Do not be concerned if the formulae look unfamiliar at this stage - we will deal with each in detail in the chapters ahead as well as many others!Journal of the Science Teachers Association of Nigeria, 36 1 and 2 , The project aimed to promote physics not only to scientists but also to the industry, schools, students and any individuals interested in physics and natural science.

Bajah etal 76 25 0. Here you will find exhibits about calculations, computers, virtual reality, the history of science, and much more. This is a simple change but it means that all units derived from these two are changed.

Table 5: All the imperial base units, except for the measure of time, are different to those of SI units.
