The undergraduates in the major of Environmental Science and Environmental Engineering frequently ignored the importance of identifying pollution sources for water environment monitoring and knew little about the techniques of identifying pollution sources. Thus, a laboratory experiment which focused on pollution sources identification in a water…

Students' epistemologies of experimental physics refer to how they understand the role of experimentation as well as the experimental operation and design and communication of results in physics. This research aimed to find whether students in inquiry-based physics laboratory activities show more expert-like epistemologies of experimental physics…

A research-style laboratory experiment composed of the synthesis of MOF-74 materials, related structural characterization, and the cutting-edge application of electrocatalytic oxygen evolution reaction (OER) has been designed toward advanced undergraduates at East China University of Technology (ECUT). The desired monometallic MOF-74 (Ni-MOF-74…

A comprehensive laboratory-style teaching activity involving the synthesis, characterization, and analysis of structure-activity relationships of metal-organic framework (MOF) nanozymes was developed specifically for undergraduates at Tianjin University. The students acquired familiarity with the general approach in synthesizing MOFs by…

Although strokes are the smallest identifiable units in Chinese words, the fact that they are often embedded within larger units (i.e., radicals and/or characters that comprise Chinese words) raises questions about "how" and even "if" strokes are separately represented in lexical memory. The present experiment examined these…

Experimental courses for undergraduate students majoring in biochemistry or related subjects often do not provide students with systematic and research-based experiences. To help students develop abilities related to laboratory techniques, data analysis, and systematic thought in biology, we performed an exploratory program that employs…

With the increasing importance in the application of the molecular biological detection technology in the field of food safety, strengthening education in molecular biology experimental techniques is more necessary for the culture of the students in food quality and safety major. However, molecular biology experiments are not always in curricula…

To introduce the randomness of a physical process to students, a chaotic pendulum experiment was opened in East China University of Science and Technology (ECUST) on the undergraduate level in the physics department. It was shown chaotic motion could be initiated through adjusting the operation of a chaotic pendulum. By using the data of the…

The COVID-19 outbreak has created turbulence and uncertainty into multiple aspects of life in countries around the world. In China, the pandemic continues to pose a great challenge to the nature of traditional in-class education in schools. Chinese education has faced the difficult decision of whether to resume in-person teaching in an…

An investigation was carried out into laboratory practical skills development and students' specific challenges in transition from laboratory chemistry at Chinese High School (HS) to a fully English style university laboratory course. To the best of our knowledge this is the first study of its type investigating practical laboratory skills for a…

This study examines scientific practices associated with scientific writing in organic chemistry in China. Although there is rapidly growing literature on the features and strategies of scientific writing, further research in this area is needed to recognize and treat scientific writing as a social endeavor to evaluate it in a more comprehensive…

This experiment is dedicated to second-year and above undergraduates who are in their experimental session of the analytical chemistry course. Grouped students are required to use a TiO[subscript 2] photocatalytic oxidation process to treat the methanol-containing wastewater that resulted from their previous HPLC experiments. Students learn to…

Embedded system is an interdisciplinary, profound foundation and practice-oriented course; at present, in the traditional teaching mode, embedded systems in colleges and universities generally have problems such as disconnected theory and practice, outdated assessment methods, and low enthusiasm of students. Arming to cultivate compound embedded…

Recent research on video lectures has indicated that the instructor's pointing gestures facilitate learning performance. This study examined whether the instructor's pointing gestures were superior to nonhuman cues in enhancing video lectures learning, and second, if there was a positive effect, what the underlying mechanisms of the effect might…

Evidence from a range of fields indicates that inventions are often inspired by drawing a parallel to solutions found in nature. However, the cognitive mechanism of this process is not well understood. The cognitive mechanism of heuristic prototype in scientific innovation was tested with 3 experiments. First, 84 historical accounts of important…
