H.E.S.S. is an array of five Imaging Atmospheric Cherenkov Telescopes located in Namibia. It is designed for observations of astrophysical sources emitting very-high-energy (VHE) gamma rays in the energy range from a few ten GeVs to several ten TeVs. The H.E.S.S. instrument consists of four identical 12 m diameter telescopes and a 28 m diameter telescope placed at the center of the array. An ambitious Astroparticle Physics program is being carried out by the H.E.S.S. collaboration searching for New Physics in the VHE gamma-ray sky. The program includes the search for WIMP dark matter and axion-like particles, tests of Lorentz invariance, cosmic-ray electron measurements, and search for intergalactic magnetic fields. I will present the latest results on dark matter search from the observations of the Galactic Centre region, the search for Lorentz invariance violation with the 2014 flare observation of Markarian 501, and the first measurement of the cosmic-ray electron spectrum up to 20 TeV. The future of the H.E.S.S. Astroparticle Physics program will be discussed.

Background. Spatial ability (SA) is a robust predictor of academic and occupational achievement. The present study investigated the psychometric properties of 10 tests for measuring of SA in a sample of talented schoolchildren. Objective. Our purpose was to identify the most suitable measurements for SA for the purpose of talent identification, educational assessment, and support. Design. Our sample consisted of 1479 schoolchildren who had demonstrated high achievement in Science, Arts, or Sports. Several criteria were applied to evaluate the measurements, including an absence of floor and ceiling effects, low redundancy, high reliability, and external validity. Results. Based on these criteria, we included the following four tests in an Online Short Spatial Ability Battery “OSSAB”: Pattern Assembly; Mechanical Reasoning; Paper Folding; and Shape Rotation. Further analysis found differences in spatial ability across the three groups of gifted adolescents. The Science track showed the highest results in all four tests. Conclusion. Overall, the study suggested that the Online Short Spatial Ability Battery (OSSAB) can be used for talent identification, educational assessment, and support. The analysis showed a unifactorial structure of spatial abilities. Future research is needed to evaluate the use of this battery with other specific samples and unselected populations.

Objectives: To improve processes of ambulatory care for patients with type 2 diabetes in a nationwide program.Methods: Interrupted time-series analysis with audits of practice. To implement selected recommendations of national guidelines, educational outreach visits (office visits or phone discussions) were offered to all French physicians who diagnosed one case of type 2 diabetes during a six-month intervention period. Outcome measures were the number of HBA1c measurements recorded monthly in the medical insurance computer database and the proportion of diabetic patients for whom one test had been reimbursed during the previous six months (HBA1c, fasting blood glucose) or previous twelve months (serum cholesterol, serum creatinine, urine microalbumin, electrocardiogram, ophthalmologic examination).Results: A total of 15,522 office visits and 9,062 telephone discussions were performed among 22,940 physicians. The increase in the monthly proportion of the number of HBA1c tests to the total number of laboratory tests was higher during the intervention period than during the preintervention (p value<.0001) and postintervention periods (p value<.001). Between the first audit (n=651,574) and the third audit (n=911,871), HBA1c measurements increased from 41.2% to 60.5% and blood glucose measurements performed alone decreased from 38.8% to 18.7%. Urine microalbumin measurements increased from 10.6% before to 15.3% after intervention. Only a slight increase was observed for other tests.Conclusions: Physician to physician outreach visits can be an effective way to improve the processes of care for diabetes and to routinize nationwide use of practice guidelines.

Full textAbstract:
The authors undertook research on the proper strategy of operation of educational building with gravitational ventilation in historic city center with high concentration of particulate matter PM10 and PM 2.5. In this facility the momentary increase in carbon dioxide concentration is often very high, and at the same time health requirements regarding atmospheric aerosol should be absolutely met. That is why long-term measurements of PM concentration outside and inside, as well as carbon dioxide concentration inside were carried out. CO2 was used also as a tracer gas for measurement of air change intensity. The article presents the first results of these tests and a correlation that occurs between the external and internal concentration of particulate matter PM 10 and PM 2.5. Due to a significant filtration effect of the external building envelope and particle deposition a potential conflict between required gravitational ventilation intensity and internal air pollution with particulate matters was partially reduced.

Full textAbstract:
Airtightness is a major issue in architectural design and it has a significant impact on the energy performance of buildings. Moreover, the energy behaviour of built heritage is due, to its singular characteristics, still a great unknown. The aim of this study is to establish a better knowledge of the airtightness of historical buildings, based on an in depth field study using blower-door tests. A set of 37 enclosures were analyzed inside eight buildings located in historical areas of a Spanish city with a significant built heritage. They were constructed between 1882 and 1919 and include diverse construction typologies applied for many building uses such as residential, cultural, educational, administrative and emblematic. The results indicate lower values compared to other previous airtightness studies of historical buildings. The average air change rate was found to be n50 = 9.03 h−1 and the airtightness of the enclosures presented a wide range of between 0.68 and 37.12 h−1. Three main levels of airtightness were identified with two thirds of the tested samples belonging to the intermediate level between 3–20 h−1. To conclude, several correlations have been developed which provide a method to estimate air leakage and could serve as a basis for energy performance studies of these kinds of building.

This study has aimed to measure the effect of electronic tests on the academic achievements of middle school students in Arabic course. The sample has been divided into two groups; the experimental group and the non-experimental group after using the mixed experimental method. Statistical measurements had been used before, and after, the experiment for both groups; whereas, study tools were consisted of achievements test and focus group. The results have assured the existence of statistical differences between the experimental group and non-experimental group in the (language classification) category marks. The results have shown no statistical differences on the audio comprehension, reading comprehension, writing, handwriting skills, language style, grammatical function and writing expression categories marks, which give preferences to use the electronic test rather than the traditional (pen and paper) test. The study has concluded that teachers must be encouraged to perform continuous evaluation throughout the academic semester by applying electronic tests. They must emphasize on the importance of grounding rules and regulations to apply electronic tests in the educational institutions.

Full textAbstract:
In the last three decades, important progress has been made toward more efficient statistical techniques for detecting Differential Item Functioning (DIF). However, the findings are scant when it comes to explaining DIF. Multilevel regression models can expand the knowledge of DIF causes, specifying a DIF parameter that varies randomly over items and testing hypotheses on sources of DIF shared by item bundles. The present study uses multilevel logistic regression to identify the item characteristics that could explain the presence of DIF in short tests or questionnaires, which are usually used in psychological and educational assessment. The usefulness of the approach is tested on measurements of the attitudes toward science of Spanish and English pupils obtained from the OECD Programme for International Student Assessment database.

Full textAbstract:
Many Namibian teachers experience difficulties in actualising the principles of learner-centred education, one of which being continuous assessment. Continuous assessment serves important formative purposes. That is, it can inform education stakeholders and help improve learners’ progress in the teaching and learning environment. Although a great deal is known about continuous assessment in general, not much is yet known about how Namibian lower primary teachers actually understand and implement continuous assessment in the classroom. This study investigates the assessment practices of three Grade Three teachers in a school in Oshana Region of Namibia. The study found that although the teachers who participated in the investigation have a reasonably sound knowledge of continuous assessment in theory, they lack implementation skills. They were unable to effectively transfer what they know to what they actually do. This study found that as much as training of teachers is important, the ongoing professional development of teachers is more appropriate for enhancing a complex understanding of issues related to learner-centred education that will help them to manage continuous assessment more effectively.

Full textAbstract:
The primary purpose of this study was to capture Natural Science teachers’ perceptions of the national standardised achievement tests (SATs), with a view to illuminating whether or not they were able to interpret and use the SATs reports to inform their practice and for improvement purposes as envisaged in the standardised tests’ objectives. It further sought to investigate how the grade 7 Natural Science teachers were teaching the subject matter, with a view to understanding the performance of learners as illustrated in the 2010 SATs results. The study mainly used qualitative methods such as observations, interviews and document analysis. These were complemented by quantitative methods through the use of the questionnaires, which were used to capture the general perceptions and experiences of Natural Science teachers. Thirty-five questionnaires were sent out and ten responses were received. Quantitative data from the questionnaires were analysed by tabulation to ascertain the frequencies of responses regarding teachers’ perceptions and experiences of SATs, as indicated in different scales per indicator. Furthermore, data generated through video-taped lessons, analysis of learners’ written notes, interviews and open-ended questions from the questionnaires were inductively analyzed. The findings of the study revealed that teachers had positive perceptions towards the ideals of SATs. However, their use of the SATs reports in their teaching was inconclusive. The study also revealed that there were no policy imperatives on SATs, in particular, to guide their use in schools. It was also found that teachers were not teaching the syllabus competencies fully and their Natural Science content knowledge was inadequate. The principal recommendation is that teachers need to acquaint themselves sufficiently with the SATs reports to enable them to use the reports for their intended purposes. Furthermore, teachers need to engage in continuous professional development programmes to improve their Natural Science content knowledge, especially with regard to making information in the textbooks accessible to learners in terms of addressing competencies in the syllabus. Finally, there is a need for policy intervention from the Ministry of Education in Namibia so that the existing tensions between policy formulation and implementation are addressed.

Full textAbstract:
Since independence in 1990, Namibia’s Ministry of Education Sport and Culture has focused on curriculum and assessment reforms. The introduction of Continuous Assessment (CA) for appraising learners’ achievement was considered to be a very important aspect of teaching and learning. This study focused on the implementation of CA in schools. The study explores how the selected grade 7 Social Studies teachers understand and implement CA. This study was conducted in the Oshana region of Namibia. Four grade 7 Social Studies teachers participated from two different schools. This study was done through a case study to gain insight into the implementation of CA in schools. Semi-structured interviews, observations and document analysis were the research methods used to collect the data. The findings indicate that these teachers have a theoretical understanding of what CA implies and what role it plays and are aware of assessment strategies. However these theoretical perspectives are not translated into practice. This implies a limited understanding of CA and reflects a gap between the teachers’ theoretical understanding of CA and its practical implementation. The study also identified various systemic factors that hamper the implementation of CA, which include overcrowded classrooms, increased teachers’ workload by CA, shortages of resources such as textbooks and lack of professional development. The nature of pre-service teacher education the participants went through, professional development programmes that are given to teachers as in-service training and a lack of guidelines in the syllabus on how to approach continuous assessment are clearly evident in the findings as factors that contribute to the teachers’ gap between theory and practice. The study concludes that even though a number of workshops on continuous assessment were conducted, the teachers still could not implement it as expected. The study findings inform my professional context as an Advisory Teacher and that of my colleagues. Therefore it made me realize what the teachers’ needs are and what kind of support they require.

Full textAbstract:
Changes in assessment practice in education are a global issue. Colleges of Education in Namibia also need to accommodate these changes in their training programs for student teachers, to model their practice of all modes of assessment in teaching and learning. Emphasis should be placed on assessment for learning, which is formative in nature. This qualitative case study investigated the following questions: How do teacher educators understand the principles and strategies of formative assessment and how do teacher educators implement formative assessment in their own teaching, which in turn serves as an example to their student teachers. I used three methods of collecting data: interviews, observation and document analysis. The data identify a range of findings in the teacher educators' professed understanding of formative assessment and how it is implemented in their own practice. The data also identify challenges facing the teacher educators in terms of setting a good example to their student teachers in the area of formative assessment. This study also offers suggestions for further studies on formative assessment. These include a suggestion for teacher educators to look at their own practice of formative assessment principles and strategies. A major cross department study could be conducted that includes teacher educators from different subject areas to see to how the implementation of formative assessment in the college varies from one department to another. A third possibility suggests a study involving student teachers from various areas of specialization in the college to see to what extent the implementation of formative assessment in the college affects their future assessment practices.

Full textAbstract:
This study researched the nature of tasks used in Grade 10 mathematics tests and end-of-year national examinations. The study was carried out in three, purposively selected, Grade 10 schools in the Ohangwena region in Northern Namibia. For the purpose of this study, a mixed method approach was employed to analyse a combination of both quantitative and qualitative data. A sample of three tests per mathematics teacher from the three participating schools and national examinations question papers for the past three consecutive years (2011-2013) were analysed using Stein, Smith, Henningsen, & Silver’s (2000) framework of cognitive demand. The study was divided into two phases. Phase 1 was the analysis of teacher test items and national examination items in terms of their cognitive demand. Phase 2 involved semi-structured interviews with three selected teachers to probe their views and find out their basis for selecting test items. The findings of this study revealed that there was no substantial difference in the distribution of the levels of cognitive demand in both tests and national examinations items. The study, however, showed that mainly tasks requiring only procedures without connections dominated the tests and the examinations. The number of higher level tasks in both tests and examinations analysed was low. There was no single task coded at level 4 in any of the teachers’ tests. Only 2% of tasks could be classified at level 4 in the examination items. The study also revealed that since tests and examinations assess the same learning objectives from the syllabus, most of the test items set by teachers were extracted from the national examinations question papers. The paper recommends that more tasks at a higher level category need to be included in assessment tasks to promote critical thinking amongst learners.

Full textAbstract:
This study is about Continuous Assessment (CA) in teaching and learning, a new concept and approach in independent Namibia. The country's education system was reformed shortly after independence in 1990 to fulfill the intention for Education for All. The Namibian education system then moved from a behaviorist to constructivist philosophy of education. The move made from one philosophy to another resulted in many changes in teaching and learning including changes in assessment in education. CA is born out of a constructivist philosophy. It is believed to facilitate learning with understanding. In this study I explored the understanding of Oshikwanyama teachers and their practice of CA in teaching and learning. Interviews, classroom observations and document analysis were used. The research focused on 10 participants in the Ohangwena and Oshana regions. The participants ranged from a Head of Department to members of the curriculum panel, subject advisors and Oshikwanyama subject facilitators as well as teachers at the classroom level. It was revealed that generally speaking, CA as a term is understood, but the practice is not well implemented. In the practice of CA, instead of learners being assessed for further learning, the emphasis is on scored marks without further assistance in learning. Further, the collection of marks during CA is often seen as largely for the purpose of contributing to the marks for summative final marks. Informal assessment which is part of CA was not given attention, which is a key factor preventing the effective use of CA in teaching and learning. Methods such as marking grids that are provided in the syllabus, as well as portfolios and learners' profiles, were not mentioned in the interviews nor observed as being in use. Participants in the study did acknowledge that they did not fully understand how best to implement CA. Overall, the evidence pointed to a conclusion that the identified shortcomings in the implementation of formative assessment is limiting the realization of the rich potential for CA as a day-to-day tool to facilitate learning for understanding in the observed classes.

Full textAbstract:
This study was carried out to investigate how Grade 10 Life Science teachers in three schools in the Omusati region of Namibia are including Environmental Learning (EL) in terms of the curriculum policy. A qualitative approach was used to generate data through document analysis, interviews and classroom observations to investigate the application of the policy of including environmental learning in classroom curriculum practice. The research was primarily directed towards examining constraints and enabling factors in the context of the three schools that participated in the study. The study revealed that teaching strategies for the inclusion of environmental learning were not widely evident, suggesting disparities between the policy of enabling environmental education through the inclusion of environmental learning across the curriculum. It was notable that teacher knowledge and interest in environmental education influence how they include environmental learning and that assessment practices narrow the scope of environmental learning in ways that do not include critical thinking and problem solving skills. The study concludes that despite diverse constraints inhibiting inclusion, the evidence suggests that the inclusion of environmental learning in Namibia’s Life Science curriculum can enable environmental education. The above main findings are used to make recommendations toward strengthening environmental content knowledge of teachers and to improve assessment practices. It was also noted that some of the environmental learning constraints could be transformed into enablers with more teacher support and by making a better link between environmental learning theories and practices. This will involve a redirection of the curriculum documents as well as the provision of other learning support materials to support environmental learning. The study has enabled me to conclude that what is happening should be encouraged so that it continues and is strengthened although the implementation of environmental learning is not as clear as the policy had mapped out.

Full textAbstract:
The relevance of our research is that for the successful development of the country in the nearest future, it is necessary to assess adequately the situation reflecting the level of knowledge of Ukrainian schoolchildren in comparison with other countries. The progress and economy of countries is very dependent on the quality of the educational system and the scientific complex. A competition in education began to exist among the traditional forms of competitions among the states. Developed countries make attempts to attract the best youth from other countries that’s why the purpose of the study is to investigate the problem of pedagogical measuring. The objective of our study is to analyze and compare students’ educational achievements in international measurements. There are many reasons to determine the importance of qualitative and quantitative measuring of educational systems and for this purpose, developed countries have organized the international testing of pupils of all ages. The article focuses on reading skills among pupils of elementary school (PIRLS testing), knowledge of pupils of the 4th and 8th forms in mathematics and sciences of nature (TIMSS testing), and a complex measuring of the «readiness for life – XXI» of 15-year-old students (PISA) – Programme for International Student Assessment). Ukraine took part for the first time in the international PISA-2018 test – a comprehensive measurement of the readiness for life of Generation-Z students born in 2002. We offer an analysis of the reaction of Ukrainian educational administrators and experts to the results of intensive two-hour measurements of knowledge and abilities of many hundreds of our adolescents from secondary and vocational schools posted on the Internet. We provide data for all tests 2000-2018 years for the first time in the pedagogical press of Ukraine. They will allow readers to evaluate their own evolution of the results of all tests. So you can find ways to improve their professional activities based on a combination of administratively recommended and own conclusions. We point to the beginning of changes in higher education and in the content of university quality ratings. The new rating (Impact Rankings 2020) also focuses on protecting humanity and environmental problems.

A cost-effective test rig is presented that allows for the experimental investigation of supersonic flows for educational purposes. The individual units for the test rig were designed and built by students as part of their degrees. The test rig allows for operating times up to 10 seconds and features a nozzle test section, that can house different test objects. The divergent part of the de Laval nozzle geometry is designed using the method of characteristics for planar two-dimensional supersonic flow. State of the art 3D printing technology has been utilized to manufacture the nozzle geometry. Both optical and pneumatic measurement techniques have been adopted for the current setup. A z-type schlieren setup with two parabolic mirrors is used to perform flow visualization. The entire run can be recorded with a digital high speed camera. Stagnation pressure and temperature are measured in the pressure reservoir. Measurements are used to demonstrate basic thermodynamic effects such as the depressurization of gas-filled pressure vessels. Schlieren photography is used to graphically derive the Mach number and some aspects of Mach waves, oblique shock waves, and expansion waves are discussed. Finally, some effects of surface roughness on the flow field are addressed in this paper. Initial tests with the untreated nozzle geometry led to a fine pattern of very weak oblique shock waves in the supersonic part of the nozzle, that were caused by the finite layer thickness of the printer.

Full textAbstract:
The underlying model for most formal educational measurement (e.g. standardised tests) is based on a very simple model: the student takes a test (possibly alongside other students). The complications of there being an instructional plan, actual instruction, interpretation of the outcome, and formulation of next steps, are all bypassed in considering how to model the process of measurement. There are some standard exceptions, of course: a pre-test/post-test context will involve two measurements, and attention to gain score, or similar. However, if we wish to design measurement to hold to Lehrer’s (2021) definition of ‘accountable assessment’ – as ‘actionable information for improving classroom instruction’ – then this narrow conceptualisation must be extended. In this presentation, I will posit a simple model that reflects the simple one-test context described above, and then elaborate on it by adding in a) a framework for design of the assessments that is keyed to educational interpretation, b) further rounds of data collection that can indicate changes in a student’s underlying ability, and c) provision for varied assessment modes that will allow for i) classroom-independent tasks that operate at the summative and meso levels, and ii) classroom-dependent tasks that operate at the micro level. The former are designed to provide a basis for triangulating student responses across different contexts, and the latter are designed to closely track the variation of student performance over time in a classroom instructional context. This framing will be exemplified in a in a K–5 elementary school that is seeking to improve the quality of instruction and students’ understandings of measure and arithmetic. The different levels of data collection will be instantiated by two different pieces of software, which operate at the micro level and the meso/summative levels respectively.

Full textAbstract:
Engine testing is a necessary but nonetheless expensive and time consuming process. Most of the facilities used to test an engine at sea level static conditions are enclosed test beds. In these facilities the existence of secondary mass flow within the test chamber and around the engine gives rise to various drag components that affect the thrust measurements. For this reason, the net thrust measured in an indoor test bed is lower than the true gross thrust delivered by the engine and measured during outdoor tests. Thrust correction factors, therefore, need to be calculated and applied. For the past five years Cranfield University has been involved in a research study evaluating the performance of gas turbines in test beds, and this work continues. Recently, Cranfield purchased a small gas turbine and invested in the design and construction of a small test bed facility that provides experimental data for the support of the analytical computational fluid dynamics (CFD) analysis. The purpose of this micro-turbojet and test bed facility is to mimic large scale facilities and provide appropriate experimental data for calculating thrust correction factors. The data are also used together with three dimensional CFD models to provide a better understanding of the aerodynamic and engine performance issues involved. Tests have been completed successfully and the facility is capable of detecting the small thrust differences between indoor and outdoor test. Thrust correction factors have been derived through a back to back process. This is an excellent result showing that the equipment is performing as designed. In addition to providing useful results and conclusions in support of ongoing research the facility is also used for postgraduate projects focusing on the performance of small engines in test beds. Analytical design tolls such as commercial CFD and in house engine performance programs are used to predict engine performance and parameters. The results are then validated against the test data. This paper describes the present state of technical progress, which is under development. Its other purpose is to describe the educational value of the analytical and experimental techniques, the objective of which is to mimic the overall engine development process.
