Aktiviteter med bruk av fysiske konkreter for å arbeide med brøk
No full textDenne masteroppgaven handler om aktiviteter med bruk av fysiske konkreter for å arbeide med brøk på barneskolen. Masteroppgaven er en litteraturgjennomgang som har til hensikt å svare på problemstillingen;
«Hvilke aktiviteter med bruk av fysiske konkreter for å arbeide med brøk på barneskolen beskrives i litteraturen?».
Datamaterialet som brukes for å besvare problemstillingen er hentet fra 2 databaser; ERIC og Education Source. Det har blitt brukt inklusjons- og eksklusjonskriterier for utvelgelse av data. Datamaterialet består av 10 artikler, som til sammen beskriver 24 ulike aktiviteter. Analysen av datamaterialet handler om hvilke konkreter som brukes i aktivitetene og hvilken matematikk det jobbes med i aktivitetene. Funnene i masteroppgaven viser at det brukes varierte konkreter i aktivitetene. Konkretene har ulike egenskaper og utforming, og kan være hensiktsmessige i ulike situasjoner. Funnene viser også at aktivitetene i datamaterialet innebærer at elevene jobber med ulike brøkkonsepter. Flere av aktivitetene involverer arbeid med grunnleggende brøkkonsepter, som for eksempel lik oppdeling av en helhet, og sammenligning av ulike brøkers størrelser. Noen aktiviteter innebærer også at elevene arbeider med mer komplekse brøkkonsepter, som for eksempel uekte brøker og regning med brøk. Generelt kan aktivitetene bidra til å motarbeide eller forhindre vanlige misoppfatninger i brøk og utfordre heltallstenking
ANALISIS DAN PERANCANGAN SISTEM INFORMASI MANAJEMEN AKADEMIK PADA SMA GAJAH MADA 3 PALEMBANG
No full textThis thesis is basically to discuss the management of information systems at the high school
Gajah Mada 3 Palembang. The objectives to be achieved in this paper is to find problems that
are currently running on the system and the authors propose a new system design to solve
problems that are found. The design of the new system is useful to expedite and facilitate the
activities in schools both for now and the foreseeable future. The method used in the
manufacture of this thesis is a method of FAST (Framework for the Application of Systems
Thinking).This method is a combination of best practices are found in many reference and
commercial methodologies. In other words FAST is intelligent framework that is flexible enough
to provide the different types of projects and strategies. The writing is done by comparing the
execution of the old system with the theory of the book that the author learned in thesis writing.
The stage on the author include: analyze problems, conduct feasibility studies, implementation
and maintenance and evaluation. With this expected to help the company streamline and
streamline its workforce
Black education in South Africa : the case of the Qadi Tribal Area, Inanda Reserve, Kwa Zulu.
No full textThesis (M.Soc.Sci.)-University of Natal, Durban, 1984.This thesis is concerned with formal education for black South Africans.
Central to the argument is an appreciation of how formal educational systems
tend to foster specific ideologies and reproduce particular social relations
which protect the interests of the state and those class interests which
are most closely reflected by it. This is demonstrated at a general level
with reference to colonial and post colonial education in Africa (Chapter 1)
before proceeding to the South African situation (Chapter 2).
In this context educational inequalities in South Africa have been systematically
entrenched by the Nationalist government following its accession
to power in 1948 in accordance with apartheid ideology and the perceived
needs of capital. Specifically education has been deployed to: a) help
maintain the proclaimed unique identity of the Afrikaner - and more generally
the white South African; b) to perpetuate the myth of white supremacy;
and c) to maintain and reproduce the social relations of racial capitalism.
As such, it is a form of discrimination and social control (now drawing an
organised and often violent black response) which aims to 'prepare' black
South Africans for distinct and inferior roles within society. This is
discussed in some depth drawing on both the 'liberal' and 'Marxist' interpretations.
Whereas the broad contours of the apartheid educational system have been
well sketched by a variety of authors, comparatively little attention to
date has been directed towards its impact on the micro level. In view of
this a detailed survey of the education that is available to the Qadi tribal
area of Kwa Zulu's Inanda Reserve was conducted by the author. This forms
the kernel of the thesis (Chapter 3). The survey focused on both 'in-school'
and 'in-community' factors to examine educational deprivation in the area.
Comparisons were also made with a neighbouring white area to illustrate the
depth of the inequalities that obtain under the apartheid framework. In
addition, an attempt was made to evaluate the potential for education related
unrest in the area by analysing pupils' aspirations and expectations.
The results of this survey highlight the urgent need for remedial action.
Consequently, Chapter 4 - taking note of the various recommendations of
inter alia the HSRC and Buthelezi Commissions - is devoted to a discussion
of possible interim measures for alleviating hardship in the educational
system. It is stressed that any attempt to adequately rectify inequality is dependent on structural change within the wider political economy.
Nevertheless, given that fundamental apartheid structures such as those
in education are unlikely to disintegrate in the immediate future, a
number of suggestions for improving black education within the present
context are considered
The application of a participatory evaluation method to the public library : the case of Tholulwazi Library, Besters Camp, Inanda, Durban.
No full textThesis (M.I.S.)-University of Natal, Pietermaritzburg, 1997.A participatory evaluation method used to evaluate development projects is
applied to the public library. The Tholulwazi Library, Besters Camp, Inanda - the first library established by the Durban Municipal Library service in an informal settlement - is the case used in the study. The developmental context of public libraries in South Africa in the 1990s provided part of the justification for this approach. This context relates to community demands for libraries along with other development services, as well as claims of developmental and educational benefit used to motivate for public library funding. Diminishing public budgets and calls for efficiency and effectiveness in the public service, suggest the need to evaluate and demonstrate impact and community benefit. In addition a survey of the literature on library evaluation since the 1970s indicates that useful, easily applicable methods of library evaluation are unavailable to the practitioner, hence the justification for considering models developed in other sectors. This thesis surveys the library evaluation literature, and then looks to trends in the evaluation of social service and development projects and programmes. An approach which combines a systematic and objectives-oriented approach, effected by a participatory methodology is selected and applied to the Tholulwazi Library.
The evaluation takes place via a questionnaire survey of a group of library
users (students), a use register and library counter-based survey;
supplemented by existing population data on the Besters area. A work group
consisting of library staff and user representatives, facilitated by the author,
conducted the evaluation. The evaluation results reflect on the validity of library planning, and quantify
and qualify the extent and type of use of students users, and the benefit
derived. These results are analysed in relation to library objectives, and the
coincidence or deviation commented upon. Recommendations for action in the
management of Tholulwazi Library are given, as well as recommendations
applicable to the planning and establishment of new libraries in other informal
settlements and townships.
Suggestions as to further use of this evaluation approach are given, in addition
to comments on the relevance and applicability of the methodology. These
focus on the strategic and managerial benefit of demonstrating a link between
library resources and activities (funded by public moneys), to use and user
benefit. The use of a participatory methodology is shown to be technically
necessary in demonstrating this link, as well as politically strategic. Valid and appropriate decision-making by management needs input from all levels, hence
the value of utilising 'multiple realities' of all groupings involved with delivery at
a particular service point, in such an evaluation.
The approach used suggests a more conscious approach to management of
libraries generally. It points to specific, periodic reflection on and analysis of the
role of the library as a social institution and the societal problems addressed.
This includes analysis of the library environment, focusing on existing and
potential target groups. The analysis applies in relation to conscious planning
procedures, as well as ongoing monitoring and periodic evaluation of
endeavours
A predictive view on Durbans flood safety: The Golden Mile protected in style
No full textDurban is the third largest city of South-Africa, located in the province of KwaZulu-Natal. The city suffers from severe floods from time to time, finding its cause in both the Indian ocean as well as the Umgeni river. The eThekwini municipality wishes a better insight in the occurrence of these floods and searches for a structural solution to protect the coastline. The eThekwini municipality has models in operation to predict the hydraulic characteristics in the ocean and the river. However, the existing models don’t represent the reality sufficiently, since the interaction between the Indian ocean and the Umgeni river is not modelled properly yet. An analysis on the area of interest has been executed. The conclusion was drawn that the Umgeni river delta was (partly) tide-dominant, meaning that the Indian ocean imposes the downstream water level. Furthermore, the wave climate was observed, as well as a look into present coastal protections. The link between the Indian ocean and the Umgeni river has been modelled using Delft3D. Since the Indian ocean imposes a downstream boundary condition (in terms of a water level) for the Umgeni river, a backwater curve might occur. First, the link is made by extending the Delft3D-model which was present for the Indian ocean only. The model has been extended all the way up to the Inanda dam. The part of the river included in the new model is approximately 32 푘푚 long. When comparing the models output at the river mouth, at the same location as a measurement point, similar behaviour can be observed. The same phase (lag) is observed, contrary to the tidal range. The tidal range in the model differs from reality, but this is due to a lack of calibration in the amplitudes of the different tidal constituents taken into account. Hence, the renewed model seems to work, but more validation still has to be done. This was not possible yet, as there is a lack of measurement stations along the river. Next to an extension of the Delft3D model, a script has been written in Python. This script is based on the empirical fit of Bresse and shows an elegant function. The results from the function in Python and the model in Delft3D are similar in a qualitative and a quantitative way. Both the models show an influence of the Indian Ocean, reaching easily to about 12 푘푚 upstream of the river mouth. This can be explained by the mild bed slope in this part. A structural solution for the flooding on the promenade at the height of North Beach was found in the form of a seawall. The most important design demand is to protect against a high water level of a 200 year return period combined with a 50 year return period wave height. These storm conditions are input for the ocean-river model, which delivers wave characteristics at the beach front, linking the structural design to the ocean-river model. After a pre-selection on design options, a Multi Criteria Analysis is carried out for the remaining eight design options. Grading is done based on criteria, representing the viewpoints of the many stakeholders involved and leading to a highest grading of a seawall in combination with an emergency barrier. Following, the water-retaining height for a vertical wall is determined. Given the the ground level height of the promenade to be 푀푆퐿 + 2.2 푚 and a total water-retaining height of 푀푆퐿 + 2.944 푚 this leads a practical construction height of 0.80 푚. Due to the limited height a reinforced concrete seawall is designed with emergency barriers for the beach entrances. The emergency barriers are designed of pinewood. Additionally, in order the fit properly in the surroundings, an integrated design is added with features like benches, thatch umbrellas and plants to disguise the construction and protect the Golden Mile in style.MDP266Civil Engineerin
Exochaenium natalense Kissling & K. W. Grieve
No full text<i>Exochaenium natalense</i> (Schinz) Kissling & K.W.Grieve, <i> <i>combinatio nova</i>.</i> <p> <i>Basionym</i>:— <i>Belmontia natalensis</i> Schinz (1894: 220).</p> <p> <i>Homotypic synonyms</i>:— <i>Exochaenium grande</i> var. <i>homostylum</i> Hill (1908: 338).</p> <p> <i>Sebaea natalensis</i> (Schinz) Schinz (1906:782), <i>nom. illeg.</i> [non <i>Sebaea natalensis</i> Schinz (1896:442)].</p> <p> Type:— SOUTHAFRICA. KwaZulu-Natal, Clairmont, 5 Aug. 1893, <i>Schlechter 3060</i> (Lectotype Z [Z000070706]!, <i>hic designatus</i>; isolectotype Z [Z000070705]!).</p> <p> <b>Nomenclatural notes:</b> —There are two sheets of <i>Schlechter 3060</i> at Herb. Z. One [Z000070706] contains five stems each with a single flower, whereas the other [Z000070705] contains a single stem from which the flower is removed and stored in a pocket. These two specimens should be considered as duplicates and thus a lectotype needed to be chosen, in accordance with the <i>International Code of Nomenclature for algae, fungi and plants</i> Arts 8.2 and 8.3 (Turland <i>et al.</i> 2018). The first author (JK) has studied the type material in detail and confirmed that both sheets represent the same taxon. The sheet with five stems contains more and better material and is consequently chosen here as lectotype.</p> <p> When Schinz transferred <i>Belmontia natalensis</i> to the genus <i>Sebaea</i> in 1906, he clearly forgot that he had already described a different and currently still accepted species, as <i>Sebaea natalensis</i> in 1896. Thus, should <i>Exochaenium natalense</i> ever be transferred to the genus <i>Sebaea</i>, it will need a new name.</p> <p> <b>Diagnosis:</b> —This species is morphologically closely allied to <i>Exochaenium grande</i> (E.Mey.) Griseb., but is markedly different in terms of its much smaller flower size of <i>c.</i> 0.8–1.5 cm diameter (<i>vs c.</i> 3.0– 4.5 cm for <i>E. grande</i>) and the arrangement of the reproductive organs, with anthers positioned at the same level as the stigma (<i>vs</i> distyly in <i>E. grande</i>), possibly indicating differences in pollination strategies. The species can also be differentiated on the basis of their ecological preferences.</p> <p> <b>Description:</b> —Annual, erect herbs, 15–20 cm tall. <i>Stems</i> simple, rarely branched from base, sometimes branched above, 4-ridged. <i>Leaves</i> sessile, opposite, 7–20 mm long, 3–6 mm broad, lanceolate, acute at apex, base narrowed, margin entire, basal leaves sometimes reduced. <i>Inflorescence</i> corymbose, lax, single to several flowered. <i>Calyx</i> of 4 or 5 free sepals, each 7–16 mm long, 3–5 mm broad, ovate-lanceolate, acuminate, with conspicuous keel-wing, 2–3 mm broad at semi-cordate base, hyaline, presence of colleters on inside base. <i>Corolla</i> pure white; tube 9.0– 14.5 mm long, infundibuliform; corolla lobes suborbicular, 5.0– 8.5 mm long, 4–5 mm broad, margins entire, apex acuminate. <i>Stamens</i> inserted ± half way up tube, at same level as stigma. <i>Filaments</i> 6.0– 9.5 mm long; <i>anthers</i>, <i>c.</i> 1–2 mm long, each with apical and 2 tiny stipitate basal glands. <i>Ovary</i> ovoid, <i>c.</i> 2–6 × 2–4 mm, bilocular, placentation axile, ovules numerous. <i>Style</i> and <i>stigma</i> 4–18 mm long, filiform. <i>Stigma</i> slightly clavate, papillose. <i>Fruit</i> and <i>seed</i> not seen.</p> <p> <b>Iconography:</b> — Hill (1908: 317, plate G). See also drawing accompanying plate K000195293 (<i>J.M.Wood 541</i>) from Royal Botanic Gardens Kew.</p> <p> <b>Distribution:</b> —This species occurs along a section of the eastern coastal region of South Africa. It is found mainly in the Port Edward district, on the border between the Eastern Cape and southern KwaZulu-Natal, South Africa. The range extends northwards to Port Shepstone (Oribi Flats) and uMzinto districts in KwaZulu-Natal. There are historical records from the greater eThekwini [Durban] area and Zululand, localities that have been transformed by urban development and agriculture. The species has been observed by the second and third authors along the eastern seaboard of the Eastern Cape, known as the Pondoland coast, between Port St Johns and the Umtamvuna River, although no specimens have been collected from this region as yet.</p> <p> <b>Ecology and habitat:</b> — The species inhabits the Indian Ocean Coastal Belt biome, in particular Pondoland-Ugu Coastal Sourveld (CB4) and KwaZulu-Natal Coastal Belt Sandstone Sourveld (CB3) (Mucina & Rutherford 2006). These vegetation types are characterised by undulating coastal plains, species-rich grasslands, rocky outcrops and forested gullies, at elevations up to 600 m. The area receives mostly summer rainfall with some rain in winter.</p> <p> <i>Exochaenium natalense</i> and <i>E. grande</i> occur sympatrically although the latter has a much wider distribution. The two species also have different ecological preferences—whereas <i>E. grande</i> is usually found in well drained grassland, <i>E. natalense</i> is always found in seasonally wet to moist grassland (sometimes even in water).</p> <p> <b>Etymology:</b> —This taxon was named by Schinz (1894), after its geographical origin, previously named Natal and now KwaZulu-Natal, in South Africa.</p> <p> <b>Conservation status:</b> —This species has a restricted distribution and is endemic to the southwestern region of KwaZulu-Natal. A small part of the region is statutorily conserved and the rest is transformed by agriculture and subsistence farming, infrastructure development and urban sprawl and for these reasons, the area is regarded as being of conservation concern (Mucina & Rutherford 2006). <i>Exochaenium natalense</i> is a habitat specialist and is fairly uncommon within this region of <i>c.</i> 1230 km 2. Because the extent of occurrence of the species is estimated to be less than 5000 km 2, based on historical collections and the authors’ observations, and because populations seem to be fragmented, and population decline is projected due to habitat loss and degradation, it is suggested that this species should be regarded as Endangered: B1ab(i–iv).</p> <p> <b>Representative specimens examined:</b> — SOUTH AFRICA.
