This paper begins with a brief historical overview that provides a context for understanding approaches to story reading in U.S. preschools. It also discusses factors that have prompted a new trend in story reading, one emphasizing story comprehension directly, not as a vehicle for developing only oral vocabulary and print-related literacy skills. This backdrop, as well as discussions of new research and achievement difficulties in school-age children, sets the stage for the author’s suggestion...

The purpose of this hermeneutic phenomenological study, conducted in southern Virginia, United States, was to understand six teachers' own images through the experiences teaching preschoolers from diverse cultural and linguistic backgrounds. Semistructured interviews were conducted with six teachers from two day care and development centers. Observations of classroom teaching added vital information to the data collected through interviews. Other tools for data collection included field notes...

Teacher education programs must provide opportunities for student teachers to explore their teaching aptitude early in the program and help them to strengthen their areas of weaknesses to prepare them for the realities of teaching. This study employed the cognitive diagnostic assessment framework, which is known to be effective in providing profiles of multidimensional and inter-related attributes, such as the teaching aptitude. The attribute mastery profiles of 1,111 participants from 6 South...

본 연구는 중학생의 컴퓨터·정보 소양과 컴퓨팅 사고력 관련 주요 변수를 탐색하고, 주요 변수가컴퓨터·정보 소양 및 컴퓨팅 사고력에 미치는 영향력을 검증하고자 하였다. 이를 위해 ICILS 2018 자료를 활용하였으며, 학생이 학교에 내재된 다층자료의 구조를 반영할 수 있도록 혼합효과 랜덤포레스트(mixed-effect random forest)와 다층모형 분석을 적용하였다. 연구 결과, 첫째, 혼합효과 랜덤포레스트는 5개 유의측정값을 활용한 반복 분석에서 매번 전통적인 랜덤포레스트에 비해 예측오차가 낮은 것으로 나타났다. 둘째,...

Graphite fibers are materials with a high specific modulus that have attracted much interest in the aerospace industry, but their high manufacturing cost and low yield are still problems that prevent their wide applications in practice. This paper presents a laser-based process for graphitization of carbon fiber (CF) and explores the effect of laser radiation on the microstructure of CF. The obtained Raman spectra indicate that the outer surface of CF evolves from turbostratic structures into a...

The aim of this work was to evaluate the dielectric properties of impregnated and activated palm kernel shells (PKSs) samples using two activating agents, potassium carbonate (K2CO3) and sodium hydroxide (NaOH), at three impregnation ratios. The materials were characterized by moisture content, carbon content, ash content, thermal profile and functional groups. The dielectric properties were examined using an open-ended coaxial probe method at various microwave frequencies (1?6 GHz) and...

Carbon micropatterns (CMs) were fabricated from a negative-type SU-8 photoresist by proton ion beam lithography and pyrolysis. Well-defined negative-type SU-8 micropatterns were formed by proton ion beam lithography at the optimized fluence of 1×1015 ions cm?2 and then pyrolyzed to form CMs. The crosslinked network structures formed by proton irradiation were converted to pseudo-graphitic structures by pyrolysis. The fabricated CMs showed a good electrical conductivity of 1.58×102 S cm?1 and a...

Multiwall carbon nanotubes (MWCNT) with two different (L/D) aspect ratios (7±2 μm/140±30 nm and 0.5?2 μm/8?15 nm) were surface treated using nitric acid (HNO3) and polyethyleneimine (PEI) prior to their deposition on carbon fibers (CF). Before the hierarchical reinforcement with CF-MWCNT, the CFs were treated with 3-glycidoxypropyltrimethoxysilane, a coupling agent (Z6040) and with poly(amidoamine) (PAMAM) a dendrimer containing an ethylenediamine core and amine surface groups. The MWCNT...
