Impact Of Laboratory Practical On Senior Secondary School Student Academic Achievement In SS2 Biology, Chemistry And Mathematics In Enugu North Local Government Area Of Enugu State


Abstract


This project work was carried out to determine the impact of laboratory practical on senior secondary school academic achievement in SS 2 Biology, Chemistry and Mathematics in Enugu North Local Government Area of Enugu State. The long held motion is that practical offers students a more realistic experience in science but Lunetta (2008), reported that some educators have begun to question seriously the impartation and the role of laboratory practical, they opined that practical method of teaching is not self-evident as it once seemed. The result obtained from the sample school, showed that biology chemistry and mathematics practical has a positive impact on academic performance of student. In all case that was tested, practical method of teaching biology, chemistry and mathematics was found to be superior to traditional theoretical methods. Chapter one and two is the background of the study and the review of related literature respectively. In chapter three the research method and overall design of the study was presented. Chapter four dealt with data presentation and analysis. The educational complication of the study recommendation and summary


Chapter One


Introduction

1.1 Background of the Study

According to Oxford Advance Learners dictionary (2001), “impact” means (1) A change produced by an action or cause a result or an outcome. (2) An act of one object hitting another or noticeable effect (3) An impression created in the mind of a spectator, reader etc while watching a play, listening to music or looking at a painting, impact as used in this research topic can then be defined as a positive change produced by an action, a described outcome or a result.

Laboratory is experienced as a well-equipped room for scientific experimentation (Opera mini Dictionary 2007). Where as the oxford Dictionary (2000), defined laboratory as a building used for scientific research.

The word” Practical” means connection with real situation rather than with ideas or theories (oxford Advanced Learners Dictionary, 2001). Similarly, Opera mini Dictionary (2008), Defined practical as knowledge acquired through practical or action rather than theory. Opuh, Eze and Ezemagu (2008), explained practical as a scientific study or an experimental set-up rather than dwelling in the theory and ideas on the introduction to the international senior secondary School certificate examination syllabus. West African Examination council (1998-2003) emphasized the necessity of practicals in learning science courses. (Under study in secondary schools.)

The Syllabus was designed to assess students in,

  1. Acquisition of adequate laboratory and field skill in laboratory practical
  2. Acquisition of important scientific skills, such as observation, stating of problems in the science subjects under study, great importance should be attached to experimental work and that whenever there is need for practical on any science course under study, students should be properly informed, get involved and they should apply it to what they are studying.

The national policy on education (2004), Defined secondary school or secondary education as the education received after primary education and before the tertiary stage. According to the post primary School management Board (PPSMB) Statistical records (2009) there are nine Government Secondary School in Enugu North Local Government Area.

Academic connected with education especially studying in school (oxford Dictionary 2000). According to the oxford advanced learners dictionary (2001) “achievement is defined as a thing that somebody has done successfully especially using his/her own effort and skill, web site Opera mini Dictionary (2008) defined academic achievement as something one does or achieve at school, college or university, in a laboratory class or field work.

From the foregoing, we can understand that academic achievement of student depends on the effect of laboratory practical. By providing student with practical laboratory lesson that are academically stimulating, student are more likely to engage meaningfully with tasks and subsequently may achieve higher in assessment grades (Karen et al 2009). Opuh, Eze and Ezemagu (2008), Observed in line with Addeye that “Schools which are involved in practical classes perform better in examination than those that neglect practical work’. In a nutshell, it can be understood that Biology, Chemistry, and mathematics practical have a positive effect on academic performance of student in ss2.

Okolo (2008), Defined science as the study of natural things around us which simply means the investigation of nature. Biology being a branch of science involves the study of living things (sarogini 2001). This can be proven with its following usefulness;

  1. It helps scientific research and development of new tools and techniques which invariably improve the quality of our lives.
  2. Finding application in medicine, agriculture, veterinary science and horticulture.
  3. Biotechnology, which include field, like genetic engineering and hybridism technology.
  4. Dealing with ecology problems such as overpopulation, food storage, erosion etc the study of Biology has a lot impact of reference to the b building of our nation for example,
    • The use of animal in scientific research had solved many family problems, childlessness by production of test tube babies.
    • It also stimulate our interest in the lives of living organisms and increased the enjoyment of our surroundings etc (Okolo, 2008).

Chemistry is a branch of science concerns with nature of substances and how they react with each other (Opera mini Dictionary 1997). Attraction or interaction between two people traditionally, chemistry is divided into four branches, which includes; physical chemistry, industrial chemistry, organic chemistry and inorganic chemistry (Idah. N 2008). The reference of chemistry to the building of our nation includes;

  1. Development of new tools and techniques to improve the quality of life through the production of vaccines, new drugs, new food storage system etc.
  2. Development of scientific weapons which serves as agents destroying crop pests and diseases.
    Mathematic is the study of number quantities and space.

According to Nnamonu, (2003)

  1. Students perform poorly in laboratory practical
  2. Leading to their failure in examination similarly
  3. WACE Chief Examiner (2005) report that
  4. Performance of candidate in Biology, chemistry and
  5. Mathematics fell below expectation

The report attributed candidate weakness under the following sub-heading

  1. Poor spelling
  2. Poor mathematical skills
  3. Poor dedication reasoning
  4. Poor observation
  5. Misinterpretation of question and
  6. Poor knowledge of biology, chemistry and mathematics.

The examiner lamented that “there were many candidates who could not answer correctly a single question in section A in most cases, they have mild guesses and quite unrelated answer that were sometimes unscientific based on the poor academic achievement, Obidiwe (2005), stated that the objectives of laboratory practical are not being realized to a satisfactory extent. He pointed out that the poor academic achievement are caused by lack of well equipped laboratory, lack of qualified teachers, limited time table hours, poor observation, poor clearing and poor comparison of specimen etc. This poor state of affairs is disturbing.

From the website (2010), opined that chemistry and mathematics practical have impacts on the academic achievement of SS2 students because they help:

  1. In harnessing the power of numbers, which makes life easier.
  2. To know that everything they see around in a matter.
  3. To be creative since mathematics involves a creative process (Steven Strogatz, 2010).
  4. In the use of variety of strategies in problem solving including calculation. Measurement of term and analysation of figures (website. 2010) .

In this research work, there are two variables, which are to be noted. The dependent and independent variables. The academic achievement of students is dependent variables, which depends or relies on laboratory practical, which is the independent variable for support.

Enugu North Local government Area is in Enugu East Senatorial District of Enugu State, Nigeria. The area is predominantly on urban settlement with a few rural communities. Some of the communities in Enugu North Local Government Area includes; Enugu Ngwo, GRA, Coal Camp, lva-Valley, independent Layout, Ogui and Asata.

This study was on impact of laboratory practical on senior secondary school student academic achievement in SS2 biology. Four objectives were raised which included: Laboratory practical affect or impact the academic achievement of SS2 student in biology, Chemistry and mathematics equally or otherwise, Laboratory practical have positive impact on SS2 students academic achievement in biology, chemistry and mathematics equally or otherwise, girls achieve more academically than boys after laboratory practical lesson/ experience in biology, chemistry and mathematics, Student knows the scientific skills they ought to acquire from practical lesson in the three science subject under study, how academic lesson achievement of student from rural school compare with those of their counterparts from urban schools following practical lesson experience in biology, chemistry and mathematics respectively. In line with these objectives, two research hypotheses were formulated and two null hypotheses were posited. The total population for the study is 200 staff of selected secondary schools in Enugu North local government of Enugu State. The researcher used questionnaires as the instrument for the data collection.

Descriptive Survey research design was adopted for this study. A total of 133 respondents made up principals, vice principals administration, senior staff and junior staff was used for the study. The data collected were presented in tables and analyzed using simple percentages and frequencies


5.3 Conclusion

From the results obtained in the study on the effects of modes of laboratory activities on students’ achievement in science, it was found out that: Students taught biology, chemistry and mathematics using group laboratory activity performed better than their counterparts, taught biology, chemistry and mathematics using individual laboratory activity. Male students performed better than their female counterparts in science subject achievement test but that was due to chance factors as the difference was not statistically significant. There was no significant interaction effect of mode of laboratory activities and gender on students’ mean achievement score in science.


5.4 Recommendation

Based on the findings of this study, and their implications, the following recommendations were made.

  1. Science teachers should be trained on how best to involve students into group laboratory activity during science practical instructions so as to facilitate students’ achievement in the lesson. This could be achieved through seminars and workshops for teachers in secondary schools.
  2. Teachers should make teaching and learning of biology gender friendly.
  3. The curriculum planners should ensure that they laboratory activity approach in science curriculum, as it will help to promote students’ achievement in the subject.
  4. In view of the fact that group laboratory activity was more effective in enhancing student’s achievement in science practical than individual laboratory activity, the Ministries of Education should ensure that textbook authors should incorporate group laboratory activity in the instructional methods for secondary schools biology practical.
