Enhancing Direct Instruction on Introductory Physics for Supporting Students’ Mental-Modeling Ability
Authors: Mansyur Jusman , Darsikin Darsikin
Published: May 2016

This paper describes an instructional design for introductory physics that integrates previous research results of physics problem-solving and the use of external representation into direct instruction (DI). The research is a part of research in obtaining an established instructional design to support mental-modeling ability. By integrating with the previous research results of problem-solving and external representation with the characteristics of DI, we obtained stages of a hypothetical design. The hypothetical design has been developed by implementing phases of formative research to obtain a final model of enhanced direct instruction (EDI). Results of experimental phase showed that EDI can support the students’ mental-modeling ability.
Humidity effects on tribochemical removal of GaAs surfaces
Authors: Yu Bingjun , Gao Jian , Jin Chenning , Xiao Chen , Wu Jiang , Liu Huiyun , Jiang Shulan , Chen Lei , Qian Linmao
Published: May 2016

Defect-free tribochemical removal of gallium arsenide (GaAs) was demonstrated in vacuum, dry air, and various humidity environments by scratching with a SiO2 tip. The removal depth increases with increasing relative humidity (1–90%), and reaches its maximum value in water. A perfect crystal matrix without defects was observed in the cross section of the scratched groove using a transmission electron microscope. A model based on reactive tip scratching-induced oxidation, water solubility of debris, and adhesion effect was proposed to interpret tribochemical removal of GaAs surface. This study provides new insights into defect-free and site-controlled nanofabrication of GaAs.
Land surface and atmospheric conditions associated with heat waves over the Chickasaw Nation in the South Central United States
Authors: Lee Eungul , Bieda Rahama , Shanmugasundaram Jothiganesh , Basara Richter Heather
Published: May 2016

Exposure to extreme heat was reconstructed based on regional land‐atmosphere processes from 1979 to 2010 in the South Central U.S. The study region surrounds the Chickasaw Nation (CN), a predominantly Native American population with a highly prevalent burden of climate‐sensitive chronic diseases. Land surface and atmospheric conditions for summer heat waves were analyzed during spring (March‐April‐May, MAM) and summer (June‐July‐August, JJA) based on the Climate and Ocean: Variability, Predictability, and Change maximum temperature definition for heat wave frequency (HWF). The spatial‐temporal pattern of HWF was determined using empirical orthogonal function (EOF) analysis and the corresponding principle component time series of the first EOF of HWF. Statistically significant analyses of observed conditions indicated that sensible heat increased and latent heat fluxes decreased with high HWF in the South Central U.S. The largest positive correlations of sensible heat flux to HWF and the largest negative correlations of latent heat flux to HWF were specifically observed over the CN. This is a significantly different energy transfer regime due to less available soil moisture during the antecedent MAM and JJA. The higher sensible heat from dry soil could cause significant warming from the near surface (>2.0°C) to the lower troposphere (>1.5°C), and accumulated boundary layer heat could induce the significant patterns of higher geopotential height and enhance anticyclonic circulations (negative vorticity anomaly) at the midtroposphere. Results suggested a positive land‐atmosphere feedback associated with heat waves and called attention to the need for region‐specific climate adaptation planning.
Preparation of 1,2,4,5‐tetrasubstituted imidazoles over magnetic core–shell titanium dioxide nanoparticles
Authors: Khazaei Ardeshir , Moosavi‐Zare Ahmad Reza , Gholami Fatemeh , Khakyzadeh Vahid
Published: May 2016

Magnetic core–shell titanium dioxide nanoparticles (Fe3O4@SiO2@TiO2) were applied for the efficient preparation of 1,2,4,5‐tetrasubstituted imidazole derivatives by the one‐pot multi‐component condensation of benzil with aldehydes, primary amines and ammonium acetate under solvent‐free conditions. The catalyst was synthesized and studied using several techniques including X‐ray diffraction, transmission electron microscopy, field‐emission scanning electron microscopy and energy‐dispersive X‐ray spectroscopy.

The use of educational comics in learning anatomy among multiple student groups
Authors: Kim Jiyoon , Chung Min Suk , Jang Hae Gwon , Chung Beom Sun
Published: May 2016

Understanding basic human anatomy can be beneficial for all students, regardless of when, or if, they will later undertake a formal course in the subject. For students who are preparing to undertake a formal anatomy course, educational comics on basic anatomy can serve as a concise and approachable review of the material. For other students, these comics can serve as a helpful and fun introduction to the human body. The objective of the comics in this study was to promote an understanding of fundamental human anatomy through self‐learning among students. Based on the authors' previous teaching experience, these anatomy comics were produced in a simple, direct style. The comics were titled after the two main characters, “Anna” (a girl) and “Tommy” (a boy). These comics were then presented to groups of elementary school students, high school students, premedical students, and medical students to assess the comics' ability to enhance student interest and comprehension of basic anatomy. Quiz scores among high school students and premedical students were significantly higher among participants who read the educational comics, indicating a deeper comprehension of the subject. Among medical students, close reading of the comics was associated with improved course grades. These educational anatomy comics may be helpful tools to enrich a broad spectrum of different students in learning basic human anatomy.
