Effect of Know-Want-Learn (KWL) Differentiation and Jigsaw Cooperative Learning Strategies on Students’ Performance in Social Studies (Published)
The study investigated effects of Know-Want-Learn (KWL) differentiation and Jigsaw Cooperative Learning (JCL) strategies on the performance of Social Studies students at the Junior Secondary School (JSS) level in Port Harcourt Local Government Area of Rivers State. Two research questions and two corresponding hypotheses guided. The study adopted the quasi-experimental pre-test post-test control group design. The study involved three groups. Two experimental groups (Know-Want-Learn (KWL) differentiation learning strategy and Jigsaw Cooperative Learning (JCL) strategy) and a control group taught with traditional learning strategy. The sample consisted of 177 (90 male students and 87 female students) Junior Secondary School II (JSS II) students drawn from three Government Co-educational Secondary Schools. A 25 multiple choice test items, title “Social Studies Achievement Test (SOSAT)” developed by the researchers which covers two topics: Meaning and Consequences of Drug Abuse and Harmful Substances, and Dangers of Drug Trafficking in the Junior Secondary School II Social Studies Curriculum Scheme of Work was the research instrument. The instrument was validated and had reliability coefficient of 0.84 via Kuder Richardson (KR-21) for a measure of its internal consistency. The relevant data gathered were analyzed with mean, standard deviation, graphical plot associated with Analysis of Co-variance (ANCOVA). The findings of the study showed that Know-Want-Learn (KWL) differentiation and Jigsaw Cooperative Learning (JCL) strategies could improve the performance of junior secondary school students in Social Studies. However, the interaction effect of Know-Want-Learn (KWL) differentiation, Jigsaw Cooperative Learning (JCL) strategies and gender on students’ performance in Social Studies was not significant. Hence, it was recommended among others that teacher training workshops should be organized and sustained for Social Studies teachers across the country, exposing them to innovative strategies that encourage active learning and teaching for the 21st century learner and teacher.
There is a growing need today for teachers to tailor their instructions to meet the different learner profile and learning styles in the classroom. The ESL teacher has greater challenges given that the English language has become a global language, and that most ESL classrooms include students with a wide variety of academic needs, cultural backgrounds, learning styles, and languages. Differentiated instruction is the panacea to cater for all these challenges faced by the ESL teacher in this globalized era. In a differentiated classroom, the teacher closely assesses and monitors skills, knowledge levels and interests to determine effective ways for all students to learn; thereby ensuring learner-centredness, equity and inclusive education. This paper explores how content, method, material and assessment can be differentiated in a Reading Comprehension English as a Second Language class. The issues in this paper are based on the social development theory as propounded by Vygotsky (1978)
GENERIC STRATEGIES EMPLOYED BY FOOD AND BEVERAGE FIRMS IN KENYA AND THEIR EFFECTS ON SUSTAINABLE COMPETITIVE ADVANTAGE (Published)
The focus of this study was on competitive strategies that firms adopt in the Kenya beverage industry in order to create above average performance. The fundamental basis of above industry performance is sustainable competitive advantage which is either created by low cost or differentiation strategy. The study aimed at establishing the generic strategies food and beverage firms in Kenya employ for sustainable competitive advantage. This research entailed a descriptive study design. Descriptive design uses a set of scientific methods to collect raw data and create data structures that are used to describe the existing characteristics of a defined target population. This study sought to do that among the F & B firms in Kenya. The study population consisted of 138 food and beverage manufacturing firms in Kenya registered with the Kenya Association of Manufacturers (KAM) by 2011. The data was tested for central tendency and dispersion after confirmation of normal distribution by appropriate tests of normality. Since the sample size was 32 (over the minimum 30 required for statistical analysis), regression analysis was carried out and interpretation of results of tests of hypothesis done. The research showed that 56.2 percent of the firms embrace duo strategies of cost leadership and differentiation simultaneously while 25 percent were exclusively on cost leadership and 18.8 percent were exclusively using differentiation. The use of dual strategies is a company survival tactic in terms of diversification of risks especially in very competitive environments like that of the Kenyan F&B industry. Results from Pearson’s rank correlation coefficient between the dependent variable Y and the independent variables X1 and X2 gave coefficients of 0.653 and 0.279 respectively which was an indication of positive correlation.
