Development and Validation of Teachers’ Assessment Belief of Mathematical Thinking Instrument

<p style="text-align: justify;">This study was conducted to corroborate in understanding the teachers’ beliefs about assessment practices. The prior studies related to teachers’ assessment beliefs in mathematics have been done to assess teachers’ beliefs in the general context of mathematics teaching. This study developed an instrument to assess teachers’ assessment beliefs of mathematical thinking. The research aimed to develop and validate a scale of assessment beliefs of mathematical thinking by using the confirmatory factor analysis. The first draft of the scale contained 25 items. The sample of the study consisted of 537 mathematics teachers from public schools in Oman. The instrument was a questionnaire with a 5-point Likert scale. The scale was validated by asking a number of experts in mathematics educational measurement and evaluation. Exploratory and confirmatory factor analysis was applied to test the model of assessment beliefs of mathematical thinking scale using AMOS 25.0. All constructs had acceptable reliability. The model had a good model fit for the assessment beliefs of mathematical thinking scale which obtainable from the fit indices tests. The findings revealed that all fit criteria indices were realized. The results also showed acceptable validity and construct reliability for the scale.</p>

First-year engineering students' computational reasoning abilities

Computational thinking is an essential skill set for today's students, given the digital age in which we live and work (CT). Without a precise definition, it is generally understood to be a collection of abilities and attitudes required to deal with difficulties in any aspect of life, whether or not a computer is involved. Measurement and evaluation of students' progress in CT abilities are critical, and this can only be done using instruments that have been tested and shown to work before. New students at the Basque Country's University of the Basque Country's Engineering Degrees are tested for critical thinking, algorithmic thinking, problem solving, cooperation and creativity using a previously proven tool.

Effect of a Misidentified Centre of a Type ASG Material Measure on the Determined Topographic Spatial Resolution of an Optical Point Sensor

The article presents the determination of the topographic spatial resolution of an optical point sensor. It is quantified by the lateral period limit DLIM measured on a type ASG material measure, also called (topographic) Siemens star, with a confocal sensor following both a radial measurement and evaluation, as proposed by ISO 25178-70, and the measurement and subsequent evaluation of two line scans, proposed by the NPL Good Practice Guide. As will be shown, for the latter, an only slightly misidentified target centre of the Siemens star leads to quite significant errors of the determined DLIM. Remarkably, a misidentified target centre does not necessarily result in an overestimation of DLIM, but lower values might also be obtained. Therefore, a modified Good Practice Guide is proposed to determine DLIM more accurately, as it includes a thorough determination of the centre of the Siemens star as well. While the measurement and evaluation effort is increased slightly compared to the NPL Good Practice Guide, it is still much faster than a complete radial measurement and evaluation.

The reasons for the gap between the results of the test of secondary school students in Taif and the results of the general and achievement test: أسباب الفجوة بين نتائج اختبار طلاب المرحلة الثانوية بالطائف وبين نتائج اختبار القدرات العامة والتحصيلي

The current study aimed at the reasons for the gap between the results of the test of high school students in Taif and the results of the general aptitude and achievement test from the viewpoint of students, teachers, educational supervisors and school leaders To achieve the objectives of the study, the researcher used the descriptive and analytical approach. Two questionnaires were prepared, a questionnaire for students, and the other was distributed to teachers, supervisors and educational leaders. The study sample reached (343) by (193) students and (150) teachers, an educational supervisor and a school leader. The gap regarding students is ranked according to importance as follows: In the first place, fear of the tests leads to failure to perform with an average of (4.1), and in the second place, "students were not trained in the school on tests similar to the aptitude and achievement tests" with an average of (3.97). With regard to teachers, educational supervisors and school leaders, arranged in order of importance as follows: In the first place is "deficiency in the inclusion of samples of aptitude tests and achievement tests in the curriculum" with an average of (4.49), and in the second place is a deficiency in conducting periodic experimental tests for students during the year for training on exams Achievement abilities and tests, with an average of (4.43). In light of the results of the study, the researcher presented a set of recommendations and proposals, the most important of which are: Exercise in awe, attract trainers of the offered mental skills specialists in measurement and evaluation, design tight training bags that specialize in testing general abilities.

Evaluation of Universities’ Distance Education by Students and Academicians in the Covid-19 (Coronavirus) Period: A Qualitative Research

The aim of the study is to evaluate the perspectives of students and academicians about distance education implemented by universities in the epidemic period and to determine the advantages and disadvantages of distance education to get an overall perspective. In the study, the data were obtained as a result of in-depth interviews with 12 students and 13 academicians. MAXQDA analysis program was used to analyze the data. The coded data were themed and analyzed. As a result of the analysis, concept maps were created and the analysis process was completed with interpretation. Conclusion of this study, the advantages and disadvantages of distance education applied by universities during the coronavirus period were evaluated. Recording the classes within the scope of distance education has given students the opportunity to review the classes. In this process, it is seen that education/training activities continue without any limitations on time and place. With distance education, it became possible to teach more than one class simultaneously. In this way, it became possible to reach more students in a shorter time. However, it has been found that the level of interaction between the academician and the student decreases in the distance education classes. As such, a decrease in motivation has been detected. Due to the COVID-19 pandemic, a rapid transition to distance education was made, and this rapid transition caused infrastructure and system problems. On the other hand, it is understood that a sound measurement and evaluation cannot be made in the exams applied in the distance education process.

Medición y evaluación de la comunicación en empresas seleccionadas del gremio de comunicadores de Cancún / Measurement and evaluation of communication in selected companies of the Cancun communicators union

This paper inquired about how some selected professionals from the guild of communicators in Cancún grouped in the Association of Public Relations of Mexican Caribbean (ARPCM for its initials in Spanish) use measurement and evaluation. The research approach is qualitative, since the interest was to deepen in the phenomenon studied. A bibliographic and documentary review was used to form the theorical basis, as well as a semi-structured interview conducted virtually (which was recorded and subsequently transcribed) to a non-probabilistic purposive sample. Twenty-two subjects belonging to the ARPCM were chosen who met the following conditions: to be an active member of the Association in June 2021, that the terms Public Relations, Communication or Institutional Image appeared in the title of their position, and that they had been in the position for more than three years. Out of a population of 70 active members, 22 were selected: 2 belonging to civil associations, 5 to consulting agencies, 2 to hotels, 2 to restaurants, 3 to recreational parks, 2 to real estate agencies. 2 to travel agencies and 4 representing universities, from which 13 were women and 9 were men. Among the issues on which the interview focused were their conception of measurement and evaluation, whether they were doing it, and their satisfaction with the way in which they were currently carrying out this measurement and evaluation process. Also, there were inquiries about the indicators they used and if they were associated with their communication objectives, the main methods and the use given to the results, as well as the evaluation of the internal communication, indicators employed, among others. The results showed that they give the importance that these issues deserved, but are not completely satisfied with the way they put them into practice. On the other hand, they have evaluation indicators associated with their communication objectives, but the prevalence is on the measurement of products and effects, instead of results and impacts of communication; as well as they focus on reporting activities instead of goals, objectives and results that are correlated with those of the organization. At times of the so-called “new normality”, priority has been given to actions, messages, new media, but there is still something to be done for improvement in their evaluation; which is why, in the future, emphasis will have to be placed on this. Particularly, in improving knowledge about planning, goals, objectives, metrics, indicators, and their scope, as well as the possibilities to determine effects on the organization´s audiences. In view of the above, it is concluded that there is still a long way to go for the guild of communicators in Cancún in this regard.

Virtual water flows and economic water productivity of Italian fair-trade: the case of bananas, cocoa and coffee

PurposeIn a globalized economic system, the role of agrifood production is to ensure at the same time both the population's livelihood and environmental resource conservation. The present study aims at expanding the debate on the potentials of the fair-trade in terms of environmental sustainability.Design/methodology/approachThe research presents a methodology divided into three phases: (1) the identification of the water footprint values associated with the production of bananas, cocoa and coffee imported from developing countries to Italy; (2) the calculation of the virtual water volumes used to produce the crops imported from developing countries to Italy through fair-trade; (3) the analysis of the economic water productivity, obtained by the fair-trade premium, for bananas, cocoa and coffee.FindingsThe results of this study identified and measured the amount of virtual water flows and water savings or losses deriving from the fair-trade of bananas, cocoa and coffee. The average virtual water flow related to the fair-trade imports in Italy amounts to 7.27 million m3 for bananas, 22,275 m3 for cocoa and 14,334 m3 for coffee. The research findings also highlight that fair-trade and the related premium ensures at the same time the achievement of social and institutional purposes but also the remuneration of virtual water used within the life cycle of the imported crops.Originality/valuePrevious scientific literature showed that fair-trade premium has commonly been used to finance environmental protection. No study has evaluated the environmental impacts associated with fair-trade, nor the monetary value associated with the natural resources exploited to produce crops to be exported. This empirical paper fills a literature gap in terms of identification, measurement and evaluation of virtual water flows along the supply chain processes of some fair-traded crops, also providing, through the economic water productivity approach, a useful tool for decision-makers.

Non-Destructive Measurement and Evaluation of Surface Cracks Using Ultrasonic Rayleigh Waves – A Review

Quality control and inspection methods have become a critical challenge in everyday situations of the engineering profession. This is due to the evolution of the materials used today in industry and also increasingly complex and critical nature of many of the products and structures produced with them. Ultrasonic measurement is widely used especially in oil and gas and aerospace industries. This method is used because it is effective and not involving damaging the original parts. In ultrasonic measurement there are few types of waves emitted and where one of it is Rayleigh wave or mostly known as surface wave. Surface waves are generated when longitudinal waves intersects a surface near to the second critical angle. This review paper will describe about the types of waves emitted and produce and also some of the research that has been done related to the surface wave. This research can contribute to green environment because it reduces waste by suggesting the uses of Perspex.
