The magnetocaloric effect (MCE) and the giant magnetocaloric effect (GMCE) are not included in the conventional educative programs of sciences and engineering. We consider that MCE and the magnetic systems are an interesting motivation for effective learning in the interdisciplinary field of the Electromagnetism and Thermodynamics. In this work a didactic sequence is proposed, in which science and...
The authors describe a series of implementations of a multisensory, interactive eTextbook in computational physics with multiple executable elements and various ways to include text, computational laboratories, demonstrations, and video-based lecture modules. The authors also discuss advances and setbacks in the realizations of their original vision, as well as modifications instigated by changing...
This study focuses on special requirements on MOOC adoption of Chinese higher education student group (CHESG). Firstly the factors that will affect MOOC adoption of CHESG are analyzed based on the technology adoption model (TAM). Then structural equation model is built, and ten hypotheses are proposed. In the model, the correlations between perceived usefulness, perceived reputation, willingness to...
The fuzzy rules for changing of complexity level at adaptive testing were designed. Using of fussy rules for learning objects optimal selection for generation of individual learning path is proposed. Since the limits of student's knowledge assessment is difficult to determine, it is proposed to use the fuzzy approach. There is proved that using of fuzzy approach simplifies the evaluation of student's...
Development of engineering systems brought great changes in lifecycle modeling of products. These changes widened the area of model definition, made engineering processes more conform to new demands at communication with engineers, enhanced representation of knowledge, and resulted smart functions of product model such as self adaptive characteristic. It is inevitable that development of model based...
The objectives of this research was to analyze whether the problem based learning model has a better effect than the direct instructional model towards physics learning outcomes. It also aims at using the problem based learning model for analyzing the student learning activity in an experimental class. The populations used in this research are three classes of high school students in SMAN 2 Balige,...
Teaching Quality Evaluation is an important process in all higher education institutes and is carried out after each semester. However, it is not fully reliable as students don't always fill the form with no bias whatsoever. The problem is too complex to be solved using present evaluation system. So, the main purpose of this paper is to show how to use machine learning techniques so that the system...
Aim of this article was to describe the role of 3D technologies in education. Thus, possible to understand why these technologies will help to promote the level of knowledge, and why they are needed. Whether, there are schools that teach to the same technologies in Republic of Kazakhstan. What advantages of education of 3D technologies are in?
A new Runge-Kutta method, with phase-fitted and amplification-fitted is constructed for solving first-order ordinary differential equations with periodic solutions. This new method is based on the Runge-Kutta 3/8 Rule with fourth algebraic order. In the numerical results the new method is compared with the existing method; which show that the new method is more efficient.
In this paper, a variable step size and variable order strategy ( VSVO) used in the block method is developed for solving directly the second order two-point boundary value problems (BVPs). The variable step size and variable order strategy managed to reduce the total step and assure the accuracy of the method. The proposed block method can compute the solutions at two points simultaneously and adapted...
From being video repositories of courseware to dynamic adaptive e-learning models, the Massive Online Open Courseware (MOOC) ecosystem has matured significantly leading to a wider taxonomy of MOOCs. The most recent taxonomy of MOOCs captures eight broad classifications of MOOCs. Learners have different motivational drivers to choose and consume the different categories of MOOCs. There have been in-depth...
Credit risk theory for valuation corporate bond is usually expressed as zero coupon bond. In real bond trading, the most common form of debt is coupon bond. This paper developed model of multiperiods coupon bond with classical approach as default time rule. It means that default occurs when the firm cannot fulfill its payment obligation at coupon date and/or at the maturity date. Some assumptions...
This paper will implement the use of two-point block method in the form of predictor-corrector Adams-Moulton to solve first order neutral delay differential equations (NDDES) of pantograph type. This two-point block method will compute the numerical solution at two points simultaneously. This method will approximate the solutions using constant step size. The delay solutions for the unknown function...
This paper is concerned with a mathematical derivation of the nonlinear time-discrete Technology Emission Means (TEM) model that discuss its behavior from the perspective of discrete dynamical systems. Nonlinear time-discrete dynamics tends to chaotic behavior. The addition of a control parameter into the dynamics of this model has led to new results in the field of time-discrete control systems....
Mathematical thinking involves mental operations that are facilitated by the learners' mathematics knowledge and their positive disposition towards mathematical problem solving. It improves problem solving process by adapting various heuristic strategies as well as monitoring and controlling their outcomes in meta-cognitive manner. Thus, it is vital to identify the mathematical thinking level of pre-university...

The formulae for the extended two and extended three point implicit one-step block methods will be derived using Lagrange interpolation polynomial. The stability polynomials for the methods are...
Oil palm industry is well-established in Malaysia as well in Indonesia. The industry is facing a devastating crop disease which is Ganoderma Basal Stem Rot Disease (BSR) or popularly known as Ganoderma disease caused by a fungal called as Ganoderma boninense. The objective of this study is to develop a yield loss model of oil palm due to the disease. Backward elimination based regression method was...
An alternative option pricing model is proposed, in which the asset prices follow the jump-diffusion model with stochastic volatility and stochastic intensity. The stochastic volatility follows the jump-diffusion. We find a formulation for the European-style option in terms of characteristic functions. The closed-form formulae of pricing for option are derived.
Modeling of certain complex problems in science and engineering involve fuzzy differential equations. Many fuzzy differential equations cannot be solved analytically because of the complexity of the modeled problems. In this paper, a multistep block method is proposed for numerically solving first order fuzzy differential equations using Hukuhara differentiability. The convergence of the proposed...
The study of soliton scattering of the Nonlinear Schrodinger Equation (NLSE) has brought a wide focus by researchers especially in physics field such as Bose-Einstein condensates, nonlinear optics, plasma physics, condensed matter physics, etc. This paper concentrates on the effect of potentials to the soliton scattering in the generalized NLSE, Cubic-Quintic Nonlinear Schrodinger Equation (CQNLSE)...
