Abstract STEAM education is a new concept in the field of education that focuses on fostering students' critical thinking, creative problem-solving skills, and corporation skills, which are all essential for students to succeed in the modern workforce. The integration of STEAM concept into the physics curriculum can help students solve practical problems using interdisciplinary knowledge, which helps students form core discipline literacy. This article takes the friction in "Motion and Force" in the senior one physics course as an example, takes "the Changeable Road" as the project theme, based on the 6E Design Learning Model including the process of "Scientific Inquiry" and "Engineering Design", and incorporates the concept of STEAM for the production of physics curriculum projects. The concept of the physics curriculum project is designed to provide a reference paradigm for the implementation of STEAM education in secondary schools.

Abstract In China, the most famous four normal universities setting a special curriculum for a long time which combine general education and teacher education for normal students. In this study, we used the Colorado Learning Attitude about Science Survey (CLASS) to study the learning attitudes about science changes of the normal students in the curriculum structure from 8 CLASS dimensions. The results show that: (a) the learning attitudes about science of the normal students increase with the grade increasing; (b) in the curriculum structure, the general education has a little effect on improving the learning attitudes about science of the normal students, and they gain a lot after teacher education; (c)comparing with masters of education, the undergraduates education needs to strengthen in some aspects.

Abstract To overcome the drawback that conventional dust removing method, such as electrostatic suspension or direct wiping with special lens paper, can cause damage to precision instruments and their dependence on specific dust particle properties, we present a novel acoustic-levitation device design which incorporates an initial design of a multi-axis levitation device by Marzo.A with our enhancement model based on the variation of transducers numbers and their spacing to achieve the dust removing efficiency and feasibility in real dust removal process. In this work, modeling simulation in COMSOL Multiphysics and light absorbance experiment are utilized to evaluate the distribution of acoustic fields, movement trajectory of dust particles, and dust removing efficiency. With the manufactured device based on our design, further work is carried out to characterize the varying factors that may influence the removing efficiency when output voltage generated onto motor driven board is altered, experiment shows 27.5 V is the most efficient voltage output with highest dust removal proportion in actual removing operations. The study demonstrates our design achieves higher dust removing efficiency comparing to conventional methods. Whereas our design serves the purpose to solve a practical industrial problem, this paper also shows how it can be taken into the classroom as an demonstration experiment, providing an animated way to visualize the nodes and antinodes by the levitation position of particles thus to help the students in not only understanding the physical properties of standing waves but also the connection from a classroom lab to an industrial solution.

Abstract Abstract: A course selection (CS) model is constructed based on the course enrollment database from a Chinese university in this research. By using big-data analysis on the database, we study the factors that may determine the students’ CS and we investigate how to optimize allocation of course resources. Our results reveal that the allocation of course resources (type of courses) and the recent revision of academic programs will significantly influence students’ CS. Courses on natural science and engineering (type-b courses), as well as on literature and art (type-d courses), are becoming most popular in course enrollment, which are followed by practical employment-related courses (type-c courses) such as law and management. The core courses of the major (type-a courses) are least selected. Since the new academic program was implemented, type-b courses have been becoming more popular but type-c and type-d courses are less enrolled than before. Our findings can be referenced by policy makers to improve the allocation of course resources in universities, which will benefit the students’ CS and satisfy the demands from society. Our results will also serve as important information for improving education efficiency.
