The purpose of this study was to investigate the impact of imagery interventions on the vocabulary acquisition abilities of
second grade students. A total of 15 students were randomly assigned to three different intervention conditions: Word Only,
which involves the simple verbal presentation of a vocabulary word; Dual Coding, in which a picture was paired with the vocabulary
word, and Image Creation, in which students were told to create a mental picture of the vocabulary word in their mind and
draw it on paper. These students were taught a total of 21 vocabulary words: seven animal and habitat words, seven musical
instrument terms, and seven science terms. A Latin square design was used, in which each group of students rotated through
each of the interventions, being exposed to a different treatment condition for each category of words. Participants were
measured on the number of words they were successfully able to acquire through the use of experimenter designed comprehension
measures. While no statistical significance was shown between the interventions across the word categories, a significant
difference was found between the Image Creation and Word Only interventions within the science terms category. Students also
reported that the imagery interventions facilitated the ease with which they learned the words. The findings have implications
for increasing the success of classroom instruction, specifically for presenting novel vocabulary words to early elementary
learners using imagery methods. 相似文献

Queries submitted to search engines can be classified according to the user goals into three distinct categories: navigational, informational, and transactional. Such classification may be useful, for instance, as additional information for advertisement selection algorithms and for search engine ranking functions, among other possible applications. This paper presents a study about the impact of using several features extracted from the document collection and query logs on the task of automatically identifying the users’ goals behind their queries. We propose the use of new features not previously reported in literature and study their impact on the quality of the query classification task. Further, we study the impact of each feature on different web collections, showing that the choice of the best set of features may change according to the target collection. 相似文献

Objective:The researchers used the flipped classroom model to develop and conduct a systematic review course for librarians.Setting:The research took place at an academic health sciences library.Method:A team of informationists developed and conducted a pilot course. Assessment informed changes to both course components; a second course addressed gaps in the pilot.Conclusion:The flipped classroom model can be successful in developing and implementing a course that is well rated by students. 相似文献

Located in Lafayette, Indiana, Purdue University has a well‐established history as a land‐grant university with strong science, technology, engineering, and math (STEM) programs. Purdue’s learning design and technology (LDT) program resides in the Department of Curriculum and Instruction within the College of Education. Residential PhD and master’s programs as well as fully available online master’s programs are provided. The LDT program has specialized offerings in a corporate or education track for their master’s students, embracing various needs and interest in corporate, government, and non‐profit settings as well as K‐12 and higher education settings, respectively. The LDT program has 10 full‐time well‐established faculty members, and they are actively involved in research and development activities, often involving students. The program is working on developing the knowledge and skills of the program’s graduates by incorporating innovative approaches such as competency‐based programs, badging, and portfolios. –Yeol Huh, PhD, and Sung “Pil” Kang, PhD, column editors 相似文献

This study used data from the Head Start Family and Child Experiences Survey (FACES) 2009 4-year-old cohort to examine associations among family characteristics, home and classroom environments, and the emergent literacy skills of Head Start children. Results from hierarchical linear models suggest that both family and classroom contexts play a unique and interactive role in supporting Head Start children's development of different sets of emergent literacy skills. Parental warmth was positively related to children's oral language skills (i.e., receptive and expressive vocabulary knowledge), and teachers' educational level and the quality of instructional support in the classroom were significantly associated with children's code-related skills (i.e., letter-name and letter-sound knowledge). Further, high-quality instructional support in the classroom buffered the negative influence of low maternal education on children's oral language skills. Interventions focusing on enhancing the quality of parent-child interactions, in addition to professional development for teachers designed to improve the quality of instructional support, may contribute to promoting the development of emergent literacy skills of young children from low-income families. 相似文献

This essay is concerned with organisational learning and, in particular, policy learning. Sometimes, organisations learn; sometimes they do not. Sometimes they use their acquired knowledge, but this is, not always the case. 相似文献
