CHEMISTRY EDUCATION PROJECT TOPICS AND MATERIALS

Testing has always been an integral part of the educational system since its inception. The concept (testing) can be viewed as a set of tasks presented to a person, the performance of which depends on the possession of a particular body of knowledge and skill. The emphasis being laid on continuous assessment in Nigeria’s educational system has therefore given a boost to the testing system in our educational institutions. The National Policy on Education (2004) emphasizes the importance of continuous assessment by stating that “Educational Assessment and Evaluation will be liberalized by basing them in whole or in part on continuous assessment of the progress of the individual”.

ABSTRACT This study was carried out to investigate the effects of teacher made models and students made models on the achievement and interest of senior secondary school II (SSII) students in organic chemistry. The study also investigated the effect of gender on academic achievement and interest of SS (II) students in Organic Chemistry. Four research questions and four hypotheses were formulated for the study. The researcher reviewed related literature. A quasi-experimental design, specifically, the non-equivalent control group design involving four intact classes were used. The population of the study comprised 2960 Senior Secondary II (SSII) students in the forty-eight secondary schools offering chemistry in Nsukka Zone. The sample for the study consisted of 140 senior secondary II chemistry students from two co-educational schools in Nsukka Local Government Area. A purposive random sampling technique was used to select two co-educational schools that have two chemistry intact classes. The classes were assigned to the two experimental groups, Teacher Made Model (TMM) and Students Made Model (SMM) by balloting. The regular chemistry teachers of the selected schools were trained and used for the study. The instruments for data collection included the Organic Chemistry Achievement Test (OCAT) and the Organic Chemistry Interest Inventory (OCII). The “OCAT” with a reliability Coefficient of 0.97 and the “OCII” of 0.77 were developed by the researcher and validated by two experts

Cheese, a popular food across many cultures has been subject of many studies. It’s of many variants, providing huge nutritional value to humans. One of those many nutrients is calcium. Calcium helps the body in building bone structures amongst other important functions. In this study, we aimed at determining the proportion of calcium content in cheese. Thus, recommending a daily intake of cheese for Recommended Dietary Allowances (RDAs) for calcium.

Abstract The relationship between chemical structure and physical and chemical properties is essential to chemistry. Studies have shown that students have difficulty using structural representations to predict properties, which is not surprising because of the sequence of inferences that are required for sense-making. However, obtaining a nuanced model of students’ understanding depends on how information is elicited. This study investigated how the phrasing of the question prompt may elicit students’ understanding of structure–property relationships. Students were given a two-part assessment: (1) four multiple-choice questions assessing students’ self-reported abilities to predict structure–property relationships, and (2) three questions requiring students to predict, argue, and explain a boiling point trend. Two groups of students were selected to determine the sensitivity of the instrument (one with less explicit instruction of structure–property relationships and one with more explicit instruction). We found that Part I of the assessment was able to differentiate between these two groups of students. The group with more explicit instruction was further analyzed to determine how their prediction on a boiling point task connected to their arguments and explanations of the phenomenon. Even though 64% of students answered the boiling point ranking task correctly, the students typically provided less complete arguments as to why that structure had a higher boiling point. Howev

The term “class” as used in this research refers to both theory classes and laboratory classes in secondary school. Thus, the scope of the present study will be limited to chemistry as experienced by students in secondary school chemistry classes. This study will be carried out in Yenagoa Local Government Area, one out of the Eight Local Government Areas in Bayelsa State. This local government is chosen because it comprises more secondary schools in the state being the capital of the state. The class of interest is Senior Secondary II (SSII) chemistry classes.
