Age of teachers Vs ICT use in Tanzanian secondary schools: A case of Dodoma municipality
(Foundation of Computer Science, 2015) Mazoya, Adam; Ismail, Abbas; Manyilizu, Majuto
The use of Information and Communication Technology (ICT) in teaching and learning has been the main target for public and private schools in Tanzania since the beginning of the 21st century. Since then, however, the achievement of using ICT on teaching and learning has been relatively unsatisfactory due to several reasons including incompetence and poor understanding of teachers on ICT. This study intends to understand ICT literacy level, use of ICT tools in delivering contents, and readiness to adopt new methods of teaching and learning using ICT among secondary schools teachers with respect to their ages and level of education. The study was carried out in Dodoma municipality in central Tanzania for both government and private secondary schools. Questionnaires facilitated the survey methodology by involving sixteen (16) government and private secondary schools with study sample of 231 teachers. The results show that there is a positive relationship on age of teachers towards their ICT literacy. Furthermore, the study reveals that there is a significant difference between age of teachers and their highest level of education. Contrary, the findings reveal that; age is not a factor on teachers’ use of ICT tools in delivering contents, and the readiness of teachers in adopting new methods of teaching and learning using ICT. Such results provide school administration and Tanzania government a clear way on how to use and build capacity of teachers in different ways of using ICT by considering teachers' age.
Biophysical modelling of coastal upwelling variability and circulation along the Tanzanian and Kenyan coasts
(Western Indian Ocean Marine Science Association, 2020) Halo, Issufo; Sagero, Philip; Manyilizu, Majuto; Mahongo, Shigalla B.
Ocean circulation, upwelling phenomena and chlorophyll-a concentrations were investigated within the framework of numerical model simulations with 1/12 nested horizontal grid-size, in the tropical western Indian Ocean, along the coasts of Tanzania and Kenya. Ekman driven upwelling exhibited high levels of spatial and temporal variability in the region, characterized by a more vigorous occurrence/intensification during the Northeast than the Southwest Monsoon season. A similar trend was observed for chlorophyll-a distribution, but with an additional strong contribution during the inter-monsoon period from March to April. Trend analysis of a SST-derived coastal upwelling index (CUI) computed over the Pemba Channel and offshore of the East African Coastal Current (EACC), for 24 years (1990-2013), revealed a general linear relation of the form CUI (yr)= 2.4 x10-7 yr–285, with a steady small annual increase of the upwelling phenomena by 0.0024/year≃ 4% during the whole period of the simulation, which could be attributed to documented increasing trends of wind intensity and water volume transport in the region. The CUI exhibited the two most dominant peaks of variabilities on the range of annual and semi-annual timescales. The wind-stress southward component and the easting/westing veering of the northward EACC at 6 S revealed that these parameters were moderate and significantly correlated with the CUI (r=-0.53 and 0.52, p< 0.05) respectively, further suggesting its intensification during the Northeast Monsoon season.
A comparative study of ocean surface interannual variability in Northern Tanzania and the Northern Kenya bank
(WIOMSA, 2020) Manyilizu, Majuto; Sagero, Philip; Halo, Issufo; Mahongo, Shigalla B.
The livelihoods of most residents of Tanga (Northern Tanzania) and Malindi (Northern Kenya), rely strongly on fish¬ing activities in the East African shelf region. Thus, understanding variations in sea surface temperature (SST) and its related parameters such as thermocline depths and upper ocean circulation are crucial. This study applies a regional model to understand interannual spatial relationships between ocean circulation and SST off Northern Tanzania and on the Northern Kenya Bank. The results indicate slight differences in variations off the Northern Tanzanian shelf region and the Northern Kenya Bank. Such small variations might have local impacts on the human popula¬tion through influencing primary productivity and fisheries. The coastal waters off Malindi indicate stronger varia¬tions, particularly in 1997 (cold SST) and 1998 (warm SST), than those off Tanga region. The SST anomalies seem to be associated with thermocline and sea surface height (SSH) off Malindi, while off Tanga they relate only to SSH. This information provides further understanding of parameters that may affect fishing activities in these regions and can be used for planning and management processes.
Curriculum materials as a barrier to the use of communicative approach to English language teaching in EFL context: examples from Tanzania
(Politeknik Negeri Bali, 2020) Biseko, John Misana; Manyilizu, Majuto; Mwaipape, Joshua; Nyinge, Daud; Utenga, Adriano
This paper examines how curriculum materials act as a barrier to implementation of communicative Language Teaching (CLT) in English as a Foreign Language (EFL) context. It has been noted that several studies report some challenges of CLT in English language teaching. Consequently, some authors conclude that CLT is useless while others observe that the reported challenges are external weaknesses caused by users of the approach. In light of this debate, this study was conducted. Two questions were the focus of the study: how do curriculum materials respond to CLT? How does the actual use of the developed curriculum materials respond to principles of CLT? Drawing on the data obtained, authors of this study argue that curriculum materials are missing essential tasks which would facilitate a smooth implementation of CLT. Consequently, features of the traditional methods are dominating the practices. Authors advocate that it is unfair to argue that CLT is useless in EFL context but we have failed to design for it. Following the noted weaknesses, researchers recommend the adoption of task-based curriculum material design to ensure rich communicative activities in textbooks and classrooms as well.
Design of land administration and title registration model based on blockchain technology
(Materials and Energy Research Center, 2017) Kombe, Cleverence; Manyilizu, Majuto; Mvuma, Aloys
Land administration and title registration system is the system for storing land title information and managing transactions involving land titles. Due to the sensitivity of land issues, land administration and title registration system should be strong to avoid any document forgery, available all the time, and take a short time to complete tasks. Thus, this study aims at designing a model for such system based on blockchain technology. The proposed model is designed using UML diagrams and then tested for verification using statistical usage models (Markov chains). The proposed model integrates the Integrated Land Management Information System (ILMIS) with factom and bitcoin blockchains which enables encryption of information from ILMIS to get the fingerprint information of each land title and store it to the blockchains. The model further encrypts the land information from ILMIS when needed and then compare it with fingerprints from blockchains for verification. Such implementation of the proposed model will help ILMIS to have the capability of providing tamper proof for stored data, providing the self-notarization mechanism, and availability of evidence for the land title from distributed databases. Furthermore, the society is expected to benefit from this study as the time and cost for registering land title will decrease and the possibilities of a piece of land having more than one owner will not be there.
ICT usage readiness for private and public secondary schools in Tanzania: A case of Dodoma municipality
(Foundation of Computer Science, 2015) Malero, Augustine; Ismail, Abbas; Manyilizu, Majuto
The use of ICT in education has been proved to be a key milestone in improving the learning process in different levels of education. To tap this opportunity, the government of Tanzania has implemented a number of projects aimed at introducing and using ICT in different levels of education. There have been similar initiatives in the private institutions as well. However, such initiatives have been facing different challenges particularly on the readiness of using ICT for education for private and public secondary schools. Thus, this study seeks to understand ICT usage readiness between public and private schools. Results from the Pearson’s Chi Square distribution reveal that there is a relationship between the types of school with the readiness to adopt the use of ICT in teaching with private school being favored. The study has revealed that private secondary schools in Dodoma municipality are better off than public secondary schools in ICT usage readiness. Challenges for ICT usage readiness affecting the two types of schools are identified, and mitigation mechanisms to close the gap between the two types of schools are proposed. This study is significant in that it informs schools' readiness to use ICT for teaching and administrative use. It also shades light on the comparison of ICT usage between private and public schools.
Support of ICT use in Tanzania secondary schools the case of Dodoma municipality
(Foundation of Computer Science, 2016) Crallet, Victor; Ismail, Abbas; Manyilizu, Majuto
Information and Communication Technology (ICT) is a tool that changes the way education operates in terms of teaching and learning. However, the analysis available for ICT facilities in schools provides stakeholders with support at those schools. This study aims at investigating the support of ICT use in Tanzania secondary schools. The findings show that Tanzania secondary schools are lagging behind at the level of application of ICT in the teaching-learning process. The ICT facilities are lacking in schools as well as the capacity for using ICT by both teachers and students is also very low. In order to fit into the new scientific order, it is necessary for Tanzania institutions and individuals alike to develop a society and culture that places a high value on information and communication technology. The government and other education stakeholder should increase funding for the entire educational sector with emphasis on using ICT. This emphasis will help improve the level of ICT facilities in the schools. There should also be continuous and periodic training of teachers on ICT skills acquisition. Such efforts will enhance support on using ICT in education resulting to socio-economic development in the country.
The use of ICT between male and female teachers in secondary schools in Tanzania: A case of Dodoma municipality
(Contemporary Research Center, 2015) Manyilizu, Majuto; Gilbert, M. Gilbert
This paper presents the results of the study of the use of ICT between male and female teachers of secondary schools in Tanzania, where Dodoma municipality was used as a case study. The main aim was to establish the differences between male and female teachers in awareness and using ICT and attending ICT short trainings. The data were collected using questionnaires in which 231teachers from 16 secondary schools were randomly sampled. Using Chi-square tests as measure of association with p-values, the study found there is a gender imbalance of the use of ICT tools and ICT course attendance in Tanzania. Results also revealed on the comparable awareness and use of ICT applications between the groups of teachers but with larger number of male teachers seems to use ICT tools than females in both science and non-science subjects. Teachers with more than 30 years of experience demonstrated higher usage of ICT tools but seemed to find difficulties in the use of ICT applications. Understanding gender distribution on ICT areas among secondary school teachers is very important in order to utilize the ICT properly. This knowledge provides with government and stakeholder an understanding on how to balance and promote gender issues in education sectors for the betterment of the general public.
