Affective Competencies

A mathematics framework was developed to integrate problem-solving that incorporated simulation of real-life problems in the classrooms. The framework coined as the RECCE-MODEL emphasised understanding and thinking with a view on mathematics embedded in real-life. The RECCE which stands for Realistic, Educational, Contextual, Cognitive, and Evaluation encompass the underlying principles of teaching problem solving and guide teachers in planning, designing, developing, and facilitating real-life activity tasks in developing students’ problem-solving competencies in mathematics lessons. It also explores students’ cognitive competency in their application of abstract mathematical knowledge into real-life problems based on students’ developmental status of their thinking and reasoning skills correlating to Meanings, Organise, Develop, Execute and Link (MODEL). This study investigated the affective development of the students through activity tasks developed by the sampled teachers using the principles within the framework. In total, 94 students from two high schools in Brunei Darussalam responded to a students’ questionnaire constructed to address the MODEL aspect of the framework. In particular, the analyses involved the students’ affective competencies that corresponded to a 19-item instrument within the questionnaire.  The findings showed that Brunei high school students have stimulated beliefs and positive attitudes towards non-routine problem-solving in the learning of mathematics. Meanwhile, meaningful activities developed by the teachers encouraged the development of cognitive-metacognitive and affective competencies of the students. The RECCE-MODEL framework paved the way towards understanding the relationships between effective pedagogical approaches and students’ learning, and between attitudes and cognitive abilities, and also for teachers to make better-informed decisions in the delivery of the curriculum.

Uji Alpha dilakukan untuk mengetahui tingkat kevalidan e-module dengan melibatkan tiga orang ahli untuk mereview dan menilai aspek isi (konten), aspek kebahasaan, serta aspek dasain dan fitur dari e-module yang dikembangkan. Sedangkan uji Beta dilakukan untuk mengetahui tingkat kepraktisan e-module dengan melibatkan enam orang siswa dengan kemampuan kognitif yang berbeda untuk mereview dan menilai aspek kelayakan isi (konten), aspek penyajian, aspek dasain dan fitur, beserta aspek manfaat dari e-module yang dikembangkan. Berdasarkan hasil uji Alpha yang dilakukan oleh tiga orang ahli diperoleh rerata hasil penilaian masing-masing sebesar 4,90; 4,75; dan 4,51; sedangkan melalui uji Beta yang dilakukan oleh enam orang siswa diperoleh rerata hasil penilaian masing-masing sebasar 4,97; 4,78; 4,60; 4,65; 4,81; dan 4,78. Berdasarkan hasil uji Alpha dan uji Beta tersebut maka e-module pada materi suhu, pemuaian, dan kalor yang dikembangkan dinyatakan sangat valid dan sangat praktis. E-Module pada materi suhu, pemuaian, dan kalor yang telah dikembangkan dapat dimanfaatkan oleh siswa dan guru sebagai sarana pembelajaran di sekolah serta sebagai sarana belajar mandiri oleh siswa dirumah.  This study aims to develop an e-module on the material of temperature, expansion, and heat that is valid and practical. The methodology of development used in this research is the development model consisting of three stages: the planning stage, the design stage, and the development stage. E-Module was developed using the Flip PDF Professional program on the material of temperature, expansion, and heat. After going through the planning and design stages, the researcher conducted Alpha and Beta tests on the development stage. The Alpha test was conducted to determine the level of validity of the e-module by involving three experts to review and assess the aspects of the content, the linguistic, and the design and features of the developed e-module. Meanwhile, the Beta test was conducted to determine the level of practicality of the e-module by involving six students with different cognitive abilities to review and assess the eligibility of the content, the aspects of presentation, the design, the features, and the benefits of the developed e-module as well. Based on the Alpha test results conducted by three experts, each obtained an average result of 4.90, 4.75, and 4.51. However, the Beta test results were conducted by six students, each obtained an average result of 4.97, 4.78, 4.60, 4.65, 4.81, and 4.78. In conclusion, the Alpha and Beta test results show that the developed e-module on the material of temperature, expansion, and heat is declared to be very valid and very practical. So, e-module has been developed to benefit students and teachers as a learning tool at school and as a means of independent learning by students at home.

Artificial Neural Networks (ANNs) have proven to be a powerful tool for solving a wide variety of real-life problems. The possibility of using them for forecasting phenomena occurring in nature, especially weather indicators, has been widely discussed. However, the various areas of the world differ in terms of their difficulty and ability in preparing accurate weather forecasts. Poland lies in a zone with a moderate transition climate, which is characterized by seasonality and the inflow of many types of air masses from different directions, which, combined with the compound terrain, causes climate variability and makes it difficult to accurately predict the weather. For this reason, it is necessary to adapt the model to the prediction of weather conditions and verify its effectiveness on real data. The principal aim of this study is to present the use of a regressive model based on a unidirectional multilayer neural network, also called a Multilayer Perceptron (MLP), to predict selected weather indicators for the city of Szczecin in Poland. The forecast of the model we implemented was effective in determining the daily parameters at 96% compliance with the actual measurements for the prediction of the minimum and maximum temperature for the next day and 83.27% for the prediction of atmospheric pressure.

There is no doubt that the fourth-order King’s family is one of the important ones among its counterparts. However, it has two major problems: the first one is the calculation of the first-order derivative; secondly, it has a linear order of convergence in the case of multiple roots. In order to improve these complications, we suggested a new King’s family of iterative methods. The main features of our scheme are the optimal convergence order, being free from derivatives, and working for multiple roots (m≥2). In addition, we proposed a main theorem that illustrated the fourth order of convergence. It also satisfied the optimal Kung–Traub conjecture of iterative methods without memory. We compared our scheme with the latest iterative methods of the same order of convergence on several real-life problems. In accordance with the computational results, we concluded that our method showed superior behavior compared to the existing methods.

Some of industrial and real life problems are difficult to be solved by traditional methods, because they need exponential number of calculations. As an example, we can mention decision-making problems. They can be defined as optimization problems. Ant Colony Optimization (ACO) is between the best methods, that solves combinatorial optimization problems. The method mimics behavior of the ants in the nature, when they look for a food. One of the algorithm parameters is called pheromone, and it is updated every iteration according quality of the achieved solutions. The intuitionistic fuzzy (propositional) logic was introduced as an extension of Zadeh’s fuzzy logic. In it, each proposition is estimated by two values: degree of validity and degree of non-validity. In this paper, we propose two variants of intuitionistic fuzzy pheromone updating. We apply our ideas on Multiple-Constraint Knapsack Problem (MKP) and compare achieved results with traditional ACO.
