    EFFECT OF ADVANCE ORGANIZER TEACHING STRATEGY ON SECONDARY SCHOOL STUDENTS’ CONCEPTUAL UNDERSTANDING OF STATISTICS TOPICS IN MATHEMATICS IN MERU SOUTH, KENYA
    (Chuka University, 2022) Wairambu, Kithinji Rugendo; Wanja, Mercy; Jagero, Nelson
    This study investigated the effect of advance organizers teaching strategy on the secondary students’ conceptual understanding of topic statistics in mathematics, in Meru South, Kenya. The learning requirement in the 21st centuary is to develop life long learners who are able to cope with emerging issues in life. Mathematical knowledge and skills are required especially in high technological advancements in society. They are made of of principles, theories, constructs and concepts that need to be developed to meet emerging challenges. Topics in mathematics have unique level of learning challenges. This has made many students to perceive the subject as difficult leading to poor performance as compared to sciences such as biology, physics and chemistry. Mathematics instructional methods have been identified among the factors contributing to the problem of poor performance in secondary schools mathematics in Kenya. This study, therefore, sought to reverse this trend in performance. The research was based on constructivists’ theory pioneered by Ausubel. Solomon four quasi- experimental research design was used. Students in the experimental groups (E1 and E2) were taught using advance organizer teaching strategy and students in the control groups (C1 and C2) were taught using convectional teaching methods. The target population was all Form two students in 56 public secondary school of Meru. Purposive sampling was used to draw four Co educational schools in Meru South. Assignment of the schools to either experimental or control group was done through simple random sampling. The sample size of the study was 168 students.’ The instrument was Mathematics Conceptual Understanding Achievement Test (MCUAT). The research instrument was pilot-tested in a school in a secondary school with similar characteristics as the study sample in Maara Sub - County. Reliability was estimated using cronbach coefficient alpha method. The instrument yielded a reliability coefficient of 0.75. Data was analyzed using descriptive statistics (mean and standard deviation) and inferential statistics (t-test, One-way ANOVA and Post-Hoc) analysis which was undertaken using Statistical Package for Social Sciences version 25.0 at 0.05. The findings established that students taught using advance organizers had a higher level of conceptual understanding of statistics topic than those taught using conventional teaching methods. Thus mathematics teachers should ensure there is proper planning and preparation of learning materials to be presented prior to lesson presentation.

    Influence of ISO 9001:2008 quality management system on the tangibility of services offered in public universities in Kenya
    (Educational Research International, 2017-08) Mbaka, Peter Kimanthi; Jagero, Nelson; Njagi, Mercy Wanja; Omolo, Jonathan
    Universities in Kenya sought ISO 9001: 2008 Quality Management Systems to guarantee adherence to the University’s processes and procedures, to ensure excellence in the pursuit of their objectives and to meet customer’s requirements on quality service delivery. The purpose of this study was to determine the influence of ISO 9001:2008 Quality management systems on the tangibility of services offered in Kenyan Universities. The study adopted a descriptive research design. The study population comprised of 305, 214 members of academic staff, administrative staff and students from 30 public universities in Kenya chartered by 2016. Simple random sampling was used to select 9 public universities from 30 public universities. From the selected 9 public universities, proportionate sampling was used to select 72 members of academic staff, 90 members of administrative staff and 222 students. The study established that tangibility of service is to a great extent influenced by adoption of ISO 9001:2008 QMS in public universities. The study recommends that public universities should investigate the possibility of a gap between service quality requirements in standard operating procedures of ISO 9001:2008 QMS on tangibles of work to minimize role uncertainty which requires that the correct facilities be provided to all staff enabling them to offer quality service.
