    ABSTRACT

    The study was conducted to identify students’ levels of conceptions of three-dimensional (3-D) organic molecular structures in Chemistry, in senior secondary schools (SS III) in Agbani education zone of Enugu State. Three research questions and two null hypotheses guided the study. Descriptive survey research design was employed for the study. The population for the study was 660 students comprising of 341 males and 319 females. Multi- stage sampling techniques were used to sample 310 respondents.

    The instrument for data collection was a diagnostic test to identify students’ levels of conceptions (DTISLC) in 3-D organic molecular structures. To ensure the validity of the instruments, the instruments were face validated by two expert from Chemistry Education and two experts from Measurement and Evaluation, all in Department of Science Education, University of Nigeria Nsukka. The data generated from the trial testing was analyzed using Kindal coefficient of concordance, and the reliability index of 0.91 was obtained.

    Frequency and percentages were used to answer research questions, while Chi-square was used to test the null hypothesis at 0.05 level of significance. Findings of the study showed that many students have partial conceptions of IUPAC nomenclature of branched or substituted 3-D organic molecular structures in chemistry. Many students also have correct conceptions of numbering of unbranched parent carbon chain, drawing of structures of simple unsubstituted molecules and differentiating between isomers and transformation of formulas. The study also found that gender has no significant influence on students’ levels of conceptions in four groups (1, 2,5and 6) out the six groups under which the concepts were discussed. The influence of school location is significant only in one group

    (3) out of the six groups. Based on the findings, the study recommended among others, that students should be kept abreast of time in chemical nomenclature of organic molecular structures through regular assignments, class quiz, etc to help them grasp that fundamental concept.


    Students’ Conceptions of Three - Dimensional Organic Molecular Structures in Chemistry

    CHAPTER ONE

    Introduction

    1.1 Background to the Study

    In Nigeria education system, science is so important that it’s teaching and learning has been greatly emphasized. Chemistry is one of the most important branches of science; which enables learners to understand what happens around them. Chemistry is a core subject for Medical Sciences, Textile Science, Agricultural Science, Synthetic industry, printing technology, Pharmacy, Chemical technology etc (Jegede, 2007). Chemistry is one of the science subjects in science curriculum that is important for any given progress in technology. It occupies a central position among all sciences (Ahiakwo, 2012). The current West African School Certificate Examination (WASCE) and National Examination Council (NECO) syllabus in chemistry contains topics in physical, inorganic, analytical and organic chemistry which is the basic focus of this study.

    Defense Procedure for Education Researchers

    In preparation for defending a project or seminar on Students' Conceptions of Three - Dimensional Organic Molecular Structures in Chemistry, it is imperative that as a nursing student, you demonstrate comprehensive knowledge of your research. The defense process is structured to include presenting your work, answering questions, and illustrating its pertinence. Initially, provide a succinct yet thorough introduction to your research topic, emphasizing its importance and the objectives, ensuring that both the audience and the External Examiner can understand the scope of your study.

    Prior to your defense, be thoroughly acquainted with your research abstract and the critical elements of Chapter One, including motivation for embarking on this research, problem statement, objectives, and significance. In Chapter Two, be ready to cite at least two references from the literature review. For Chapter Three, you should be equipped to discuss the methodologies, tools, and techniques utilized. In Chapter Four, defend your research by justifying the findings and linking them to your research objectives.

    Conclude your defense by succinctly summarizing the study and offering insightful, evidence-based recommendations. A professional dress code, such as wearing a suit and tie, is vital to create a favorable impression and elevate your presentation.

    During the question and answer segment, the External Examiner may pose questions pertaining to your research. If confronted with a challenging or irrelevant question, respond diplomatically with, “Sorry, Sir/Madam, the question asked is beyond the scope of my study.” Whenever possible, direct your answers back to your research findings to reinforce your expertise.
