This study explores undergraduate course instructors’ stated beliefs and practices toward student-centered learning. In-depth interviews with four undergraduate course instructors in a variety of disciplines in the United States revealed their beliefs about the roles of instructors’ and students’ as well as student-centered learning. Also, the instructors’ teaching styles are measured and compared with their stated beliefs and practices. Through thematic analysis and deductive and inductive...

Cobalt was electrodeposited onto chemical vapor deposition (CVD) graphene/Si/SiO2 substrates, during different time intervals, using an electrolyte solution containing a low concentration of cobalt sulfate. The intention was to investigate the details of the deposition process (and the dissolution process) and the resulting magnetic properties of the Co deposits on graphene. During and after electrodeposition, in-situ magnetic measurements were performed using an (AGFM). These were followed by...

As a replacement for activated carbon, biochar was synthesized and used for the adsorptive removal of formaldehyde and nitrogen oxide. Biochar was produced from the fast pyrolysis of the red marine macro alga, Pyropia tenera. The P. tenera char was then activated with steam, ammonia and KOH to alter its characteristics. The adsorption of formaldehyde, which is one of the main indoor air pollutants, onto the seaweed char was performed using 1-ppm formaldehyde and the char was activated using a...

Refuse-derived fuel (RDF) produced using municipal solid waste was pyrolyzed to produce RDF char. For the first time, the RDF char was used to remove aqueous copper, a representative heavy metal water pollutant. Activation of the RDF char using steam and KOH treatments was performed to change the specific surface area, pore volume, and the metal cation quantity of the char. N2 sorption, Inductively Coupled Plasma-Atomic Emission Spectrometer (ICP-AES), and Fourier transform infrared spectroscopy...

The objective of this study is to develop an assessment tool for measuring the social interactions of preschool children with autism-spectrum disorders (ASD) in an individual music therapy setting. In order to draft a questionnaire as an assessment tool, we researched the current literature, performed direct observations of preschool children with ASD, and conducted in-depth interviews with experts in the field. The drafted questionnaire went through preliminary tests and a content validity...
