Temporal Trajectory Analysis of Lake Surface Area: Case study on Lake Tana, Ethiopia | Author : Abrham Zelalem , Eyaya Belay and Abel Markos | Abstract | Full Text | Abstract :Lakes are facing challenges due to climatic and anthropogenic activities with slow changes causing
unnoticed damages over a long time. The long term historic data provides concrete evidence of change.
The earth observation satellites which include both geostationary and polar orbiting satellite provide
different types of environmental data. The main aim of this paper is to evaluate the temporal trajectory
change of the lake surface area of LakeTana from 1985
– 2015 using geospatial technologies. The
study
uses seven Landsat TM and ETM+ images to detect the lake surface area change. The change
was
examined using modified normalized difference of Water index (MNDWI) method. This was attained
by making use of ERDAS Imagine 2014 and ArcGIS10.1 software. The results of this study
indicate that within the past three decades, the lake area has shown a significant decrease–about
362.74 sq.km. The area calculated from bathymetric surveys and the ccorresponding results from other
alternative methods were gathered and computed with the findings of this study. The results portray
that there is strong relationship between the estimates of lake surface area results of MNDWI with NDVI
alongside the bathymetry results. Hence, lake surface area quantification and characterization using
remote sensing and GIS techniques enables resource managers to project realistic change scenarios
helpful for lake surface area management. |
| Challenges in Assessment Methods and Practices across Departments by Secondary School Teachers in the South West Shoa Zone, Ethiopia | Author : Aschalew Terefe Refu and Aemero Asmamaw Chalachew | Abstract | Full Text | Abstract :This study was conducted to assess the most widely used assessment methods and practices across
departments and the challenges that hinder high school teachers’ classroom assessment. To this end,
it employed descriptive survey design. Data were collected from 197 teachers’ by using questionnaire
adapted from Zhang and Burry-Stock (2003) assessment practice inventory, and some open-ended
items developed to measure challenges. The data was analyzed using quantitative data analysis methods.
Moreover,
the
findings
regarding
challenges
in
classroom
assessment
practices
from
the
qualitative
open-ended questions were analyzed and presented by content analysis using words and sentences.
The result indicated that teachers mostly use traditional assessment
methods than alternative
assessment.
It also revealed that there were statistically significant differences across departments
in constructing test items, F (2,172) = 190.849, p < .05, communicating assessment results, F (2, 172)
= 208.963, p < .05, and grading, F (2, 172) = 63.935, p < .05. In contrast, no statistically significant
differences were found across departments in analyzing test results and test revisions and using performance
assessment practices. Furthermore, teachers’ attitude and belief, shortage
of time, lack
of
resources,
assessment
training
gap
and
large
class
size
were
major
identified
challenges.
Eventually,
the
researchers would like to suggest that teachers should focus on using the alternative forms of assessment
than traditional assessment methods. |

| The Perplexity of Scholars: Media Relationships in Ethiopia: Exploring the Implications of the Democratization of the Nation | Author : Asmamaw Addis Amera and Mustofa Worku Jemal | Abstract | Full Text | Abstract :he role of media in democracy has been understood in terms of providing the general public with
information on what the voters have for the public, how politicians behave, and how citizens increase
their political participation. Scholars’ media participation has been insignificant in the democratization
process of Ethiopia despite its divergent interpretations in previous studies. Scholars’ media participation
in Ethiopia highly waning and waxing from time
to
time. Therefore,
the objective of
this exploratory
research
is to
examine
the
intricate
relationships
between
scholars
and
media in
Ethiopia.
The
research
is
mainly qualitative: Sixteen key informants were interviewed from both media people and public-
scholars.
And three FGDs were held with journalists and public-scholars. The findings have shown
that the scholar-media relationship has been weakening because of the following major factors: media
credibility went down, there are abusive uses of scholars’ opinions and expressions by the media,
there is intolerance of criticisms by the government, and thus polarized political ideologies have been
practiced by many scholars and the media. |
| Land Use/Land Cover Dynamics and Driving Forces in Simien Mountains National Park, Amhara Region, Ethiopia | Author : Ebrahim Esa Hassen | Abstract | Full Text | Abstract :The Simien Mountains National Park (SMNP) was inscribed by UNESCO as world heritage site in 1978
due to its unique landscapes and rich biodiversity resources. However, many parts of the park have
been farmed for more than 2,000 years and is seriously degraded due to unsustainable land utilization.
The
main
purpose
of
this
study
is to
quantify
the
magnitude
and
rate of
change
of major
land
use/land
cover (LULC) types by identifying the
major drivers
of
change
in SMNP
using GIS and
remote
sensing
techniques.
Three
Landsat
images
of
the
periods
between
1985
and
2015
were
classified
and
analyzed
using Erdas Emagine 13 and ArcGIS 10.1.
The results of
LULC analysis indicated that a
remarkable
expansion was observed in shrubs cover by 110.8% (79 ha/y) followed by
farmland and
settlements
by
53.7% (81 ha/y) between 1985 and 2015 although some portions of their original
extent
were
converted into other LULC classes.
The results also indicated that the reduction of areas under
forests
and
grassland covers by about 56.4% (98 ha/y) and 49% (142 ha/y) were evident. The major
institutional
and policy factors identified in the study area were civil war between 1976 and 1991,
changes in political structure and land reform of 1997. However, population pressure in the park was
the most important human factor of land use and land cover change. Therefore, sustainable management
in the park is vital to curb the biodiversity depletion and loss of tourist attractions in the area. |
| Multivariate Analysis of the Predictors of Women’s Delivery at a Health Facility: Evidence from 2016 Ethiopian Demography and Health Survey | Author : Kassahun Tegegne | Abstract | Full Text | Abstract :The prevalence of women’s health institutional delivery in developing countries, particularly in Ethiopia
is very low. The empirical data show that migration and socio-demographic factors are responsible
for low institutional deliveries in developing countries. Therefore, the overall objective of the study
was to establish whether there were differences in women’s access to delivery facilities across the
different migration status and socio-demographic factors. To achieve this objective, a cross-sectional
analysis of data from 2016 Ethiopian Demographic and Health Survey (EDHS) was
conducted.
The
2016 EDHS interviewed a total of 15, 683 women,
aged 15
to 49 years both in rural and urban
areas. Out of
the 15,683 interviewed women, only 7590 women who had live birth(s)
in
the last
five
years preceding the survey were taken as a study participant. The bivariate and multivariate
analysis results show that urban to urban migrants and urban to rural migrants were more likely
to deliver at a health facility than those from other migration status. In relation to socio-demographic
factors, women who live in rural areas, women with no education, non-working women, older women,
women with high birth order and women in the poorest wealth index were less likely to deliver
at a health institution. Therefore, maternal health remains a public health concern due to lack of
sufficient access to delivery facilities. Attention should be given on migration and socio-demographic
factors
that are responsible to inhibit women’s
institutional
delivery.
The
government should target
the most vulnerable groups such as rural women, non-working women, women in the poorest
wealth category and women with high birth order to further reduce maternal mortality in the country. |
| Attitude of Junior and Secondary School Students towards Basic Science Subjects in North Gondar, Ethiopia | Author : Missaye Mulatie | Abstract | Full Text | Abstract :Education has become one of the most powerful weapons to reduce inequality and poverty (UNESCO,
2000). The main purpose of this study was to investigate attitude of junior, secondary and preparatory
school
students towards basic
science subjects
in
North
Gondar. The
study used a quantitative
research
approach with
cross-sectional survey design. To this end, 150 junior/secondary and preparatory
school students who were selected from North Gondar zone to attend kiremt (rainy season)
STEM
(Science, Technology,
Engineering and Mathematics) training
at
University
of
Gondar
participated
in the study. Data were collected through self-report questionnaire
and analyzed using inferential
and
descriptive statistics.
The
results indicated that those students scored high on attitude towards
basic
science subjects (chemistry,
biology
and
physics) and
had excellent Grade
Point Average.
Besides,
there
was
no
significant
difference
in
attitude
towards
basic
sciences
between
male
and
female
students.
Most
importantly,
attitude
towards
science
significantly
influenced
Grade
Point
Average
on
chemistry
and
biology subjects.
Here,
career
interest
was
found
to be
the
most
important
predictor
of
achievement
in biology. But, the adoption of positive attitude toward science was the most important
factor
to explain achievement in chemistry. Career interest and adoption of scientific attitudes are vital
dimensions
influencing
students’
achievement
in
chemistry
and
biology
respectively.
Overall, this
study concludes that attitude towards science has a collosal influence on students’ achievement in
chemistry, biology and physics. Therefore, institutions such as the Ministry of Education, teachers, and
parents should plan and work in tandem to maximize students’ positive attitude towards chemistry,
biology and physics education. |
| Historicizing Urbanism: The socio- economic and cultural pattern of the city of Gondar, Ethiopia | Author : Muluken Fikadie, Sisay Sahile, Busha Taa | Abstract | Full Text | Abstract :The establishment of Gondar in the 17th century marked a very promising chapter in the history of the
Ethiopian urbanization. This research aimed at exploring the meaning of urban space, the change of
meaning through time and effects of displacement on the social bonds. In doing so, qualitative method
(document analysis, interview, observation, photo voices) were used for thematic analysis. Various social
institutions
such
as
religion,
market,
monarchy,
and
long-distance trade
promoted
the
Gondarian
urban
development. All
the three Abrahamic religions, namely,
Christian, Islam,
and
Judaism were
developed
in urban Gondar. Although these religions meant
to divide the communities, the
Gondarian
Markets
served to unite and glue the believers of
these religions together.
However,
the
residential
places
were segregated on the basis of religions, leading
to sprawling. The sprawling was ensued by
unplanned
urban expansion, triggering
developmental
imbalances
across
the
city.
The
corrective remedy
of redevelopment injected by the municipality also caused slums
of despair. Despite these shortcomings,
urbanization marshalled with holistic
goals
of making Gondar one of the icons of the Ethiopian
centers
of religion and culture tinorder to promote and maintain national unity. |
