Pedagogical Techniques Teachers Use to Bolster Extensive Reading Habits in Secondary Schools in Kenya

This study addresses the issue of pedagogical techniques for extensive reading in secondary schools in Kenya at a time when concern is being expressed about declining reading habits in the institutions of learning. Learners nowadays have taken to social and mass media and rarely read anything extra outside the prescribed texts. Even the wide spread national examination malpractice witnessed recently could be traced to the decline in reading interest and poor reading habits among secondary school learners. Effective use of pedagogical extensive reading techniques can greatly improve learners’ achievement in English and also enhance their reading habits. This study was prompted by the observed poor reading in English by secondary schools learners in Laikipia County in Kenya. Among some of the possible explanations for this scenario are that students in the County did not adequately read books extensively coupled with other determinants that influence their performance in English. The study investigated the pedagogical techniques used by teachers to bolster extensive and pleasure reading habits. The study was guided by The Schema Theory. The descriptive survey research design was used for this study. Fifteen secondary schools in Laikipia County were sampled by proportional stratified sampling technique in five sub-counties across the county. Purposive sampling was used to sample 30 out of 80 (37.5%) English language teachers. Simple random sampling was used to sample 327 students out of about 2670 students (12.24%) in form 2 and 3 in the County. The research instruments used for data collection included: questionnaire for students, interview guides for teachers and documents analysis guide. The instruments were pilot tested to ensure validity and reliability in a co-educational secondary school in the neighbouring county that was not included in the study. The reliability of the questionnaire and interview guide was estimated using Cronbach’s alpha coefficient which was 0.871 which met the recommended threshold of 0.7 and above.  Analysis of data was done using descriptive statistics such as frequency, tables and percentages. Qualitative data were organized according to the study themes and presented descriptively on the basis of the study objectives. The analyzed data revealed various reading pedagogical techniques which included analysis of the title and the blurb before reading, formation of mental images while reading and writing book reviews after reading. Acute shortage of reading resources was a major hindrance to engagement in extensive reading in schools. The study recommended that schools should ground learners on reading techniques and also come up with strong extensive reading policy to promote independent reading.

Role of Extensive Reading Habits in Students’ Acquisition of Composition Writing Skills in English in Kenya

Despite the important role reading proficiency plays in learners daily lives both within and outside school, there has been a lot of concern from educationist, researchers and media in Kenya who have reported a saddening trend on poor reading culture among many students in Kenya, This study was prompted by the observed poor reading and writing in English by secondary schools learners in Laikipia County in Kenya. The study therefore sought to establish whether there existed any relationship between extensive reading habits and composition writing amongst learners. The study was guided by Schmidt's (1975) Schema Theory. The descriptive survey research design was used for this study. Fifteen secondary schools in Laikipia County were sampled by proportional stratified sampling technique in five sub-counties across the county. Purposive sampling was used to sample 30 out of 80 (37.5%) English language teachers. Simple random sampling was used to sample 327 students out of about 2670 students (12.24%) in form 2 and 3 in the County. The research instruments used for data collection included: questionnaire for students, interview guides for teachers and composition writing test. The instruments were pilot tested to ensure validity and reliability in a co- educational secondary school in the neighbouring county that was not included in the study. The reliability of the questionnaire and interview guide was estimated using Cronbach’s alpha coefficient which was 0.871 which met the recommended threshold of 0.7 and above. Analysis of data was done using descriptive statistics such as frequency, tables and percentages. Analysis of Variance (ANOVA) was done at 95% confidence level (F(2) = 80.933, P = .001) to establish whether there was statistically significance difference between composition writing mean scores of different categories of school using (SPSS) version 17. Qualitative data were organized according to the study themes and presented descriptively on the basis of the study objective. It was found that learners who engaged actively in extensive reading performed better in composition writing than those who did not. However, it was established that acute shortage of reading resources was a major hindrance to engagement in extensive reading in schools. The study recommended that schools should come up with strong extensive reading policy to promote independent reading so as to improve their writing skills.

Effects of land use on trip generation in urban areas : comparison between estimated trip generation rates and planning practices in Dar es Salaam, Tanzania

In developing countries cities, the development of planned urban areas is associated with rapid changes in land uses. The number of vehicles trips generation in the planned area is related to the types, patterns and characteristics of land uses in that particular area. However, still it is unclear to what extent the change of land use affect trip generation rates in urban planned areas. This study has examined the effects of land use changes on trip generation rates for different residential land uses. A methodology for deriving trip generation rates for different residential land uses was developed. Additionally, the study made comparisons between vehicles trip generation rates provided in land use and transport planning manuals for local practitioners and rates obtained in the study area. Furthermore, the study identified the factors considered by planners and policy makers in order to reduce the effects of land use change in planned urban areas. This study therefore recommended the need of conducting site or city specific vehicle trip rates rather than adopting trip rates from different transport manuals.Paper presented at the 34th Annual Southern African Transport Conference 6-9 July 2015 "Working Together to Deliver - Sakha Sonke", CSIR International Convention Centre, Pretoria, South Africa.The Minister of Transport, South AfricaTransportation Research Board of the US

Are individuals willing to pay for community-based eco-friendly malaria vector control strategies? A case of mosquito larviciding using plant-based biopesticides in Kenya

This study was carried out to assess individuals’ willingness to pay (WTP) for UZIMAX, a novel plant-based biopesticide developed for malaria vector control. The biopesticide is estimated to kill up to 100% of Anopheles larvae within 48 h of application and poses no risks to human health and the environment. However, scaling-up of its adoption requires clear evidence of its acceptance by individuals in malaria-prone areas. We conducted Becker-DeGroot-Marschak (BDM) revealed preference auctions with 204 participants to determine their willingness to pay (WTP) for community-based application of the biopesticide to control malaria vectors. Nearly all participants were willing to pay at the lowest bid price of the biopesticide, and the majority of them expressed great interest in pooling resources to facilitate biopesticide application. Household per capita income and building capacity of households through training significantly increased WTP. These findings imply high adoption potential of the technology and the need to devise inclusive policy tools, especially those that enhance collective action, resource mobilization and capacity building to empower both men and women and stimulate investment in eco-friendly technologies for malaria prevention. Financial and labor resource mechanisms managed by the community could potentially spur adoption of the biopesticides, and in turn, generate health, environmental and economic benefits to households in malaria-prone communities.The Biovision Foundation Switzerland.

Estimating the proportion of clinically suspected cholera cases that are true Vibrio cholerae infections: A systematic review and meta-analysis

Background Cholera: surveillance relies on clinical diagnosis of acute watery : diarrhea. Suspected cholera case definitions have high sensitivity but low specificity, challenging our ability to characterize cholera burden and epidemiology. Our objective was to estimate the proportion of clinically suspected cholera that are true Vibrio cholerae infections and identify factors that explain variation in positivity. Methods and findings We conducted a systematic review of studies that tested ≥10 suspected cholera cases for V. cholerae O1/O139 using culture, PCR, and/or a rapid diagnostic test. We searched PubMed, Embase, Scopus, and Google Scholar for studies that sampled at least one suspected case between January 1, 2000 and April 19, 2023, to reflect contemporary patterns in V. cholerae positivity. We estimated diagnostic test sensitivity and specificity using a latent class meta-analysis. We estimated V. cholerae positivity using a random-effects meta-analysis, adjusting for test performance. We included 119 studies from 30 countries. V. cholerae positivity was lower in studies with representative sampling and in studies that set minimum ages in suspected case definitions. After adjusting for test performance, on average, 52% (95% credible interval (CrI): 24%, 80%) of suspected cases represented true V. cholerae infections. After adjusting for test performance and study methodology, the odds of a suspected case having a true infection were 5.71 (odds ratio 95% CrI: 1.53, 15.43) times higher when surveillance was initiated in response to an outbreak than in non-outbreak settings. Variation across studies was high, and a limitation of our approach was that we were unable to explain all the heterogeneity with study-level attributes, including diagnostic test used, setting, and case definitions. Conclusions In this study, we found that burden estimates based on suspected cases alone may overestimate the incidence of medically attended cholera by 2-fold. However, accounting for cases missed by traditional clinical surveillance is key to unbiased cholera : burden estimates. Given the substantial variability in positivity between settings, extrapolations from suspected to confirmed cases, which is necessary to estimate cholera incidence rates without exhaustive testing, should be based on local data

Differences in avoidable mortality between migrants and the native Dutch in the Netherlands

BACKGROUND: The quality of the healthcare system and its role in influencing mortality of migrant groups can be explored by examining ethnic variations in 'avoidable' mortality. This study investigates the association between the level of mortality from 'avoidable' causes and ethnic origin in the Netherlands and identifies social factors that contribute to this association. METHODS: Data were obtained from cause of death and population registries in the period 1995–2000. We compared mortality rates for selected 'avoidable' conditions for Turkish, Moroccan, Surinamese and Antillean/Aruban groups to native Dutch. RESULTS: We found slightly elevated risk in total 'avoidable' mortality for migrant populations (RR = 1.13). Higher risks of death among migrants were observed from almost all infectious diseases (most RR > 3.00) and several chronic conditions including asthma, diabetes and cerebro-vascular disorders (most RR > 1.70). Migrant women experienced a higher risk of death from maternity-related conditions (RR = 3.37). Surinamese and Antillean/Aruban population had a higher mortality risk (RR = 1.65 and 1.31 respectively), while Turkish and Moroccans experienced a lower risk of death (RR = 0.93 and 0.77 respectively) from all 'avoidable' conditions compared to native Dutch. Control for demographic and socioeconomic factors explained a substantial part of ethnic differences in 'avoidable' mortality. CONCLUSION: Compared to the native Dutch population, total 'avoidable' mortality was slightly elevated for all migrants combined. Mortality risks varied greatly by cause of death and ethnic origin. The substantial differences in mortality for a few 'avoidable' conditions suggest opportunities for quality improvement within specific areas of the healthcare system targeted to disadvantaged groups
