Abstract
Science educators have for years, stressed on the importance of science activities to help students understand the theory and practice of science, as it influences everything about the life of an individual to that of an entire community. This chapter would like to do a conceptual and attitudinal analysis to assess the possibilities that the mass adoption of the small-scale equipment could afford Ghanaian students. Apart from the unavailability of science equipment and risks factors involved in using them, lack of electricity, water and conventional fragile equipment (some of which require training before use) have been found to be other factors that limit teachers‘ desires to organise practical activities for their students. This study seeks to present the conceptual and attitudinal changing nature of adopting micro-scale science equipment by analysing six laboratory activities from first year under graduate courses in Ghana. The main objective would be to create an awareness of the existence and possibility of using micro-scale equipment in science practical activities among teacher trainees, science educators and curriculum developers of science education in Ghana. This is likely to ensure that meaningful, safer, sustainable and concept-based science practical activities are performed in schools.

Abstract
The study was based on Piaget’s theory of Cognitive development and the main aim of the study was to find out if Piaget’s theory holds for Ghanaian early children. One hundred and eight (108) Early School children were randomly selected from three (3) public and two (3) private schools purposively selected from schools in the Winneba Municipality.The procedure used was mainly interview method using some of Piaget’s tasks to test for conservation of number. The 7-8 years old were identified to be conservers of number than the 3-6 years old. Generally, the results supported Piaget’s theory of cognitive development where the older children (7-8 years) performed better than the younger children (3-4 years; 5-6 years) at the number tasks. In conclusion, the results of this study agree with Piaget’s theory of Cognitive development that the concrete operational stage marks the development of conservation.

Hanson, R., (2018). An investigation into teacher trainees' understanding of chemical stability and its implications. C. A. Shoniregun Canada International Conference on Education (CICE-2018). UK: Infonomics Society.
Abstract
This paper portrays the way some higher education learners perceive the concept of chemical. It assesses the nature and possible origins of these conceptions. One hundred and thirty-eight teacher trainees in a teaching university, who were purposely selected, participated in this case study. These teacher trainees had exhibited persistent inabilities in deciphering between stable and reactive species in a periodic chemistry course. Instruments used in gathering data were worksheets and focus group discussions, which were analysed quantitatively and qualitatively. Records of the discussions were transcribed after thematic descriptions. It was found that more than half the trainees’ concepts of a full shell and increased nuclear charge connoting stability were the genesis for their observed alternative conceptions about chemical stability. These findings will contribute and add to existing knowledge among the science learning community. Further remediation was recommended to enable the trainees to form proper mental models of the concept of chemical stability and its application through innovative teaching.

Phyllis Forster1,*, Rosemary Quarcoo1, Elizabeth Lani Ashong1 & Victoria Ghanney1 (2017). Views of Teacher-Trainees on Clothing and Textiles Education in two Teacher Education Universities in Ghana. World Journal of Education, 7,
Abstract
The study explored the views of teacher-trainees on Clothing and Textiles (C&T) education in two teacher education universities in Ghana. The objectives were to find out whether pre-tertiary Sewing/C&T lessons provided them with small-scale business skills, and foundation for higher education, they could teach Sewing/C&T competently on internship, identify their sources of motivation, and elicit their suggestions to improve on the subject. Data collected revealed that one-tenth and two-thirds acquired small-scale business skills from their lessons at basic and secondary levels respectively. About 71% indicated they taught the subject competently on internship and career intention was their main motivating factor for the subject. For improvement, there is need to provide adequate modern facilities and competent teachers with current ideas in content and pedagogy, and good teacher relationship with students and industry. Other suggestions were, students should remain focused and attract others to the subject through their dressing. Feed-back from the teacher trainees indicates that Sewing/C&T education in Ghana provides occupational skills and foundation for further studies. Keywords: trainee-teachers; internship; clothing and textiles; home economics; teacher education; interns

Phyllis Forster., Magdalene Aba Aggrey and Adwoa Nyantakyiwaa Amoah (2018). Menopause and food among women in a perl-urban community in ghana. International Journal of Current Advanced Research, 7,
Abstract
In a descriptive survey, this study explored menopausal symptoms of 120 women aged 40-60 years and the food they ate among the Six Food Groups of Ghana. Questionnaire was used to collect the data which were analysed with the SPSS to generate frequencies and percentage tables for discussion. More than half of the menopausal women experienced mood swings; hot flashes; reduced work output; fatigue; sleeplessness; and weight gain.The main vegetables consumed by all the women were tomatoes, onions, pepper, garden eggs and kontomire (cocoyam leaves). Majority ate fish; maize; mango, orange, apples, pear, banana, and palm oil. A moderate percentage ate rice, wheat, cow peas, soy oil and frytol; minority ate animal foods other than fish; starchy roots and plantain; beans, nuts and oily seeds, carrots cabbage, cucumber, French beans and spring onions, green pepper and lettuce; beverage, fruit drink and fresh fruit juice. The women restricted themselves to a few of the nutritious local foods among the Ghana six food groups that they could take advantage of to reduce or prevent their menopausal challenges. The researchers recommend that menopausal women increase the variety, frequency and portions of fruits and vegetables consumed especially because of their phyto-estrogen, boron and fibre content; topics on nutrition and menopause should be included in the Home Economics curriculum; and Home Economists and Nutritionists in the community should organize talks on Nutrition and Menopause for women groups

Quarcoo,R (2018). Factors Influencing Low Performance of Pupils in BDT Sewing at a Junior High School in Efutu Municipality. International Journal of Innovative Research and Development, 7,
Abstract
Abstract: The study design was a descriptive survey which sought to get answers to the following research questions: ‘What factors accounts for the low performance of pupils in BDT sewing at a particular JHS in Efutu Municipality, Ghana?’ How can pupil’s interest in BDT (Sewing) be enhanced? A purposive sampling technique was used to get a sample size of 100 respondents. A questionnaire was used to collect data and descriptive statistical tools were used to analyze the close ended questions and a thematic approach was adopted for analyzing the open ended questions. Majority of the respondents agreed that, factors influencing the low performance of pupils in BDT (Sewing) include, students consider it unimportant, teaching and learning of BDT sewing is boring, many topics in BDT sewing are difficult. The provision of teaching and learning resources, the effective use of teaching learning resources and strategies, organization of fieldtrips, allocation of more time to BDT ( Home Economics) were suggested as ways of enhancing students’ interest in BDT(Sewing). Keywords: Factors, low performance, pupils, basic design and technology (BDT), sewing

Quarcoo, R., & Tounaa, G. (2017). The Use of instructional Materials and selected Activity Methods of Teaching: A Tool for Improving the Performance of Clothing and Textiles Students.. International Journal of Innovative Research and Development., 6,
Abstract
Abstract: An action was taken to improve upon the performance of Clothing and Textiles students in a selected Senior High Technical School in Ghana using instructional materials and selected activity methods. The objectives were: To arouse and sustain students’ interest in Clothing and Textiles through the use of realia, charts, pictures and illustrations.; Use practical or demonstration to assist students to understand the concept learnt better and set standards for their individual practical.; Use group projects to improve their learning. Forty two SHS two Clothing and Textiles students were purposively sampled and observational guide, questionnaire, class exercises, quizzes and examinations were used for the data collection. Interventions such as vigorous use of instructional materials, hands on practice (practical), encouraging continuous learning by giving practical project work to students and constantly giving prompt feedback to students after an evaluation were put in place. The data was analysed using frequency distribution and percentages. The results showed a tremendous improvement in student’s performance. It is recommended that Clothing Laboratory and other resources needed for teaching and learning of Clothing and Textiles should be provided for the school and Clothing and Textiles teachers should use varied methods for teaching the subject and insist on practical approaches since the subject is a practical- oriented one. Keywords: Instructional materials, activity methods, improving, performance, clothing and textiles
