In this paper, we present a functional variable method for finding periodic wave and solitary wave solutions of complex nonlinear evolution equations in mathematical physics and engineering sciences. The proposed technique is tested on the generalized Zakharov equation and higher-order nonlinear Schrödinger equations. The method is straightforward and concise, and it can also be applied to other nonlinear evolution equations in applied mathematics.  相似文献

This research was carried out to investigate the effect of the 5E learning method and 5E method enriched with REACT strategy on student achievement in science education. The research was carried out with 64 first-year students (30 in the experimental groups, 34 in the control groups) in the Department of Primary Education at a state university in the spring semester of 2017–2018 in the context of “Acids, Bases and Salts”. The pre-test/post-test quasi-experimental design with a control group was used in this study. In the experimental group, the 5E method enriched with the REACT strategy was used while the computer-assisted 5E instruction method was used in the control group. The data were collected by means of a “Subject Achievement Test”, consisting of open-ended questions. The dependent t test results of the experimental and control group revealed a significant difference in favour of the post-test in both groups. According to the independent t test results of the groups, the 5E method enriched with REACT strategy was found to be more effective in order to improve student achievement compared to computer-assisted 5E learning method.

This study explored the structural relationships among secondary school students’ conceptions, self-regulation, and strategies of learning science in mainland China. Three questionnaires, namely conceptions of learning science (COLS), self-regulation of learning science (SROLS), and strategies of learning science (SLS) were developed for investigating 333 Chinese high school learners’ conceptions, metacognitive self-regulation, and strategies in science. The confirmatory factor analysis results verified the validity of the three surveys. Moreover, the path analyses revealed a series of interesting findings. Learners with lower-level COLS, namely “memorizing,” “testing,” and “practicing and calculating,” tended to use surface learning strategies such as “minimizing scope of the study” and “rote learning.” However, learners’ higher-level COLS, namely “increase of knowledge,” “applying,” “understanding,” and “seeing in a new way,” had complicated connections with their SROLS and SLS. On the one hand, learners’ higher-level COLS had negative relations to “minimizing scope of the study” and “rote learning.” On the other hand, their higher-level COLS were powerful predicators for their metacognitive self-regulation and further affected their use of “deep strategy” and “rote learning.” Though Chinese secondary students with higher-level COLS usually have a negative view of “rote learning,” the functioning of their metacognitive self-regulation may change their initial attitudes towards the surface strategy. Learners with higher-level COLS still used “rote learning” as a prior step for achieving deep learning. Therefore, we concluded that the SROLS played an important mediating role between the COLS and SLS and may change learners’ original intention to utilize learning strategies.  相似文献

ABSTRACT: A math review exam, written and administered in conjunction with the Quantitative Assessment Program at the Univ. of Wisconsin-Madison, is used at the beginning of the 1st food engineering course to evaluate math skills needed for successful completion of the course. Students who do not score well on the math exam are targeted for individual remedial work to help bring their math skills up to a level that allows successful completion of the food engineering course.  相似文献

Acoustic micromanipulation technologies are a set of versatile tools enabling unparalleled micromanipulation capabilities. Several characteristics put the acoustic micromanipulation technologies ahead of most of the other tweezing methods. For example, acoustic tweezers can be adapted as non-invasive platforms to handle single cells gently or as probes to stimulate or damage tissues. Besides, the nature of the interactions of acoustic waves with solids and liquids eliminates labeling requirements. Considering the importance of highly functional tools in biomedical research for empowering important discoveries, acoustic micromanipulation can be valuable for researchers in biology and medicine. Herein, we discuss the potential of acoustic micromanipulation technologies from technical and application points of view in biomedical research.  相似文献

In this paper, we study higher-order boundary value problems for higher-order nonlinear differential equations having convolution terms. We extend and prove some theorems for nonlinear differential equations by using the differential transform method.  相似文献
