The implication of the soliton solutions attained with arbitrary constants can be substantial to interpret the involuted phenomena. The established soliton solutions show that the approach is broad-spectrum, efficient, and algebraic computing friendly and it may be used to classify a variety of wave shapes. We analyze the achieved solitons by sketching figures for distinct values of the associated parame...

One hundred and seven students from6th grade and 48 students from 8th grade were selected randomly from three middle schools forthe study. A questionnaire, which was developed by the first researcher, including two openended questions, eleven multiple choice questions, and one true-false question was prepared foreach group. Students solved each question and explained how they solved them. Also, it wasrequested verbally to fill in the solutions. Besides these questions, it was requested from thestudents to answer how they use the subjects of multiplication and factors in their daily lives andhow these subjects affected their attitudes and treatments towards mathematics. According to theevaluations of this research, some suggestions were made for students’ learning difficulties andconcept misunderstanding about multipliers and factors. </p

For the definite values of the parameters, some well-established and advanced solutions are accessible from the general solution. The solutions have been analysed by means of diagrams to understand the intricate internal structures. It can be asserted that the method can be used to compute solitary wave solutions to other fractional nonlinear differential equations by means of fraction...

By utilizing the oncoming - expansion technique, a series of novel exact solutions in terms of rational, periodic, and hyperbolic functions for the fractional cases are derived. These types of long-wave propagation phenomena played a dynamic role to interpret the water waves as well as mathematical physics. Here, the form of the accomplished solutions containing the hyperbolic, rational, an...

As a symbolic calculator, the TI-92 is equipped with Derive which is a symbolic calculation program and Cabri which is a geometry program. This study only dealt with the part concerned with the program Derive. First of all we determined the potentials and limitations, then we seek a response to the question which «benefits» can we expect at the learning level of the students?

TI-92 hesap makinesi bir sembolik hesap programı olan Derive ve bir geometri programı olan Cabri programlarıyla donatılmıştır. Bu araştırmada sadece Derive programı ile ilgili olan kısmı incelenmiştir. İlk olarak yeterliliklerini ve sınırlılıklarını belirledikten sonra, öğrencilerin öğrenme aşamasında, ne gibi « faydalarını » bekleyebiliriz sorusuna cevap arayacağız.

The research sample consists of 43 prospective elementary teachers from an education faculty of a state university in Turkey. The data were obtained from the answers the prospective elementary teachers wrote on the working papers that include various styles (multiple choice, true–false judgments selection, and open-ended) of questions. Both quantitative and qualitative assessment tools were employed in the analysis of the data.
