Information Communication Technology Pedagogical Integration in Mathematics Instruction among Teachers in Secondary Schools in Kenya

This paper reports finding of the study that sought to ascertain the extent of ICT-pedagogical integration in mathematics instruction among secondary school teachers in Kenya. Information was sought on professional development experiences and needs in computer technology use in mathematics instruction, the type of computer software used in mathematics curriculum content delivery, the influence of accessibility to ICT infrastructure and technical support, teachers’ competence and confidence on ICT integration in mathematics teaching and learning. This was a descriptive survey of explanatory nature that involved 200 mathematics teachers from schools who were selected using proportionate stratified sampling techniques. Data was collected using questionnaires, interview and observation schedules. The data collected was analyzed using descriptive statistics involving computation of frequencies and percentages and inferential statistics that included Pearson correlation and multiple regression analysis. Results show that there is limited use of ICTs in mathematics instruction which is attributed to low self confidence and incompetence in use of ICTs and inaccessibility to appropriate software materials and technical support. There is need to equip schools with the necessary ICT infrastructure including content specific software and technical support. There is also need for professional development of teachers in ICT pedagogy as they require the knowledge and skills to put these tools in practice.

MATHEMATICS TEACHERS' CONCEPTIONS ABOUT PROBLEM SOLVING AND ITS INFLUENCE ON THEIR CLASSROOM PRACTICES IN SECONDARY SCHOOLS IN KENYA

The study investigated secondary school mathematics teachers’ conceptions of problem solving and their classroom practices. The study was based on theoretical frameworks represented by Anderson (1996), Ernest (1991) and Bernardo (2002). The study was conducted in selected secondary schools in Uasin Gishu County, Kenya. Simple random and stratified sampling techniques were used to select 20 teachers from twenty schools. Data was collected using questionnaires, interview schedule and classroom observation checklist. Both descriptive and inferential statistics were used to analyze the data. In general, the results of this study indicated that there was no significant correlation between teachers’ conceptions about problem solving and their classroom practice. The results of this study also showed that teachers tend to hold strong conceptions about problem solving that are consistent with the instrumental view. In view of the findings, it was recommended that in-order to gradually challenge the teachers’ negative conceptions about mathematical problem-solving, adequate educational interventions should be planned and implemented in teacher education programmes and that teacher educators should assist and support teachers in concretizing these conceptions by undertaking reforms at both the pre-service and in-service training levels.  Article visualizations

Examining User Acceptance of Computer Technology: An Empirical Study of Student-Teachers in Kenya

The use of computer technology in schools has made slow progress even though the government has been generous in funding as evidenced in the Kenya Education Sector Support Programme (KESSP). It is therefore important to understand how and when teachers use computer technology in order to devise implementation strategies to encourage them. This study investigated student teachers’ perceptions of computer technology in relation to their intention to use computers. The purpose is to shed light on more effective ways to promote the use of computer technology in schools. Based on an expanded variation of the Technology Acceptance Model, a survey of student teachers’ perceptions were collected at local universities in Kenya. Overall, the results indicated that: (1) student teachers perceived usefulness of computer technology had a direct significant effect on their intention to use it; (2) student teachers perceived ease of use had only an indirect significant effect on intention to use; however, (3) student teachers’ subjective norm, that is the possible influence of external expectations, did not have any direct or indirect significant effects on their intention to use computer technology

Pedagogical Factors Affecting Integration of Computers in Mathematics Instruction in Secondary Schools in Kenya

The paper reports findings of a study which sought to examine the pedagogical factors that affect the integration of computers in mathematics instruction as perceived by teachers in secondary schools in Kenya. This study was based on the Technology Acceptance Model (TAM). A descriptive survey design was used for this study. Stratified and simple random sampling techniques were used to select a sample of 200 teachers that was drawn independently and randomly from the stratum of secondary schools. Questionnaires, interview and observation schedules were used to collect data from respondents. Data was analyzed using descriptive statistics frequencies and percentages and inferential statistics including one way analysis of variance and regression analysis. The results indicate that mathematics teachers’ use of computer technology is significantly related to pedagogical factors such as knowledge and skills in computer, perceived usefulness, access to hardware and software and technical support and pedagogical routine practice. The study provides a basis upon which recommendations on appropriate remedies can be formulated to enhance the integration of computers in mathematics instruction by teachers. This also provides a guideline for the selection of sound instructional approaches in mathematics instruction in secondary schools.

Evaluation of a modified multipurpose cassava processing machine for size reduction

The production of cassava (Manihot esculenta) is considered an important alternative to a reduction in food scarcity around the world. Kenya is rapidly gaining prominence due to the declining production of staple foods, especially maize and wheat. Though still considered a poor man’s food, the usage of cassava has greatly diversified in terms of both industrial and domestic applications. This coupled with the introduction of improved varieties and better farming options calls for innovative ways of handling the increasing volumes of fresh cassava tubers to minimize post-harvest losses. One of the important postharvest processes is size reduction which is achieved by either chipping or grating. Improved production methods alone are not adequate to solve the issues of field losses in cassava production. Factors affecting the efficiency of size reduction operation include operator experience, disc type, disc speed, cutting clearance and moisture content. Conventionally, this has been done manually but due to the inherent problems, the use of machines is being encouraged through the development and adoption of chipping/grating machines. In this study, the machine developed was dual-powered and allowed conversion from a chipper to a grater and vice versa as need be. It has a capacity of 162.15kg/h and 81.62 kg/h when chipping and grating respectively. The chipping process consumed less power averaging 0.0034 kW/kg compared to 0.0075 kW/kg used in the grating and these chips dried faster than manually worked cassava.

Revisiting the modified Baermann extraction method: extraction efficiency of Radopholus similis using different extraction materials

Open Access Article; 29 Sept 2021In order to determine the threat that plant-parasitic nematodes pose to crop production, it is essential to establish an accurate estimation of their presence. The extraction efficiency from soil, therefore, is a critical step in establishing disease pressures presented by nematodes or the conditions of soil health. To achieve high nematode extraction efficiency, various methods and modifications have been developed over time (Oostenbrink, 1954; Seinhorst, 1956; Harrison & Green, 1976; Viaene et al., 2021) with variations being introduced locally, depending on the availability or access to certain materials
