This study investigates consistent and inconsistent respondents to mixed-worded questionnaire scales in large-scale assessments. Mixed-worded scales contain both positively and negatively worded items and are universally applied in different survey and content areas. Due to the changing wording, these scales require a more careful reading and answering process than scales with only one type of wording (Marsh, 1986; Schmitt & Stults, 1985). Especially poor readers might not notice the changing item wording (Marsh, 1986). Therefore, using mixed-worded scales can have unintended consequences, because not all respondents answer positively and negatively worded items in a consistent way. This study assumes and aims to identify two distinct groups of respondents to mixed-worded scales, consistent and inconsistent respondents. We argue that this population heterogeneity underlies the common phenomenon of wording-related effects in mixed-worded scales (Gnambs & Schroeders, 2017; Marsh, 1986). We investigated five datasets from three large-scale assessments. At first we included n = 4,799 15-year-old students from the USA who were surveyed in PISA (Programme for International Student Assessment) 2015, second n = 5,943 fourth-graders from Australia who participated in both TIMSS (Trends in International Mathematics and Science Study) and PIRLS (Progress in International Reading Literacy Study) 2011, and third n = 4,989 fifth- and n = 4,791 ninth-graders from Germany who participated in NEPS (National Educational Panel Study) in 2010/2011 and 2014/2015. The mixed-worded scales measured the reading self-concept in PISA and PIRLS, the mathematics self-concept in TIMSS, and the global self-esteem in NEPS. In order to identify two unobserved groups of respondents to the different mixed-worded scales, we formulated a constrained factor mixture model (e.g., Masyn et al., 2010) that operationalized these two assumed classes of respondents. We modeled the consistent class to show a response pattern that implies changing the side of the response scale (i.e. agree with positively worded items and disagree with negatively worded items or vice versa) and the inconsistent class to show the same response pattern to both item types (i.e. agreeing or disagreeing to all items). The findings of this study have different implications for the use of mixed-worded questionnaire scales in large-scale assessments as well as for future research in the field of interactions between survey instruments and respondents. The study further connects two strands of previously unrelated research, research on the detection of inconsistent/careless respondents and research on the reasons for unexpected item intercorrelation patterns in mixed-worded scales. In all five datasets, the estimated parameter patterns were in line with theoretical expectations and the mixture models consistently outperformed more traditional two-dimensional confirmatory factor analysis models. Between 7% and 20% of respondents were found to belong to the inconsistent classes. To further substantiate and validate the interpretation of the proposed model, class membership was related to a theoretically relevant characteristic of the respondents, the reading achievement. Conform with expectations, the reading achievement scores were lower in the classes of inconsistent respondents than in the classes of consistent respondents in all five datasets.

Short videos, also known as micro-videos, have emerged as a platform for sharing ideas, experiences, and life events on online social networks. This paper shares preliminary results of a study involving students from two universities who created six-second videos using the Vine mobile app to explain or illustrate technology concepts. An analysis of their videos shows that the six-second constraint often inspires creativity and critical thinking, as students need to carefully consider the message they wish to convey, and how they can do so effectively in a compelling micro-video. The creation of such videos provides a way to demonstrate student learning. [For full proceedings, see ED571430.]

Drawing on survey data from over 2000 parents, this paper explores the possibility of early-years swimming to add mathematical capital to young children. Using developmental milestones as the basis, it was found that parents reported significantly earlier achievement on many of these milestones. Such data suggest that the early years swim environment may offer enhanced opportunities for learning skills that help transition young children into formal schooling. This paper explores those milestones that are related to early mathematics.

Many studies on intercultural communication introduced how their collaborative projects were conducted. There are also several studies that discuss how intercultural collaborative activities can be integrated into a foreign language curriculum, as well as a big project (the INTENT project) that helps teachers integrate collaborative activities into their language curricula. Nonetheless, intercultural collaborative projects have not yet been mainstreamed for various reasons, such as insufficient pedagogical support from their institutions and a lack of interest in getting involved in projects among colleagues. We need to continuously examine and develop activities that can be relatively easily integrated into language curricula and that are appealing to more teachers to get involved in collaborative projects. Starting in the fall of 2013, we have been conducting a three-year experimental Facebook video project with learners of English in Japan and those of Japanese in the US. This paper will provide a brief overview of the Facebook collaboration projects and present the outcomes. [For full proceedings, see ED564162.]

Technological development offers language teachers a myriad of options for collaborative activities. Learners, in turn, benefit from increased opportunities to interact with people who can speak their target language. Research has previously highlighted the importance of developing learners' intercultural competence through such activities. The researchers implemented verbal and non-verbal activities in an intercultural collaboration project for learners of English in Japan and learners of Japanese in the U.S. This paper will detail the project activities and provide a comprehensive summary of the results, especially as they pertain to interaction with native speakers of the target language to develop verbal and non-verbal communication skills.

This paper reports on an analyis of data from a novel "Peer Instruction" application, named DALITE. The Peer Instruction paradigm is well suited to take advantage of peer-input in web-based learning environments. DALITE implements an asynchronous instantiation of peer instruction: after submitting their answer to a multiple-choice question, students are asked to write a rationale for their choice. Then, they can compare their answer to other students' answers, and are asked to choose the best peer-submitted rationale among those displayed. We engaged in an analysis of student behaviour and learning outcomes in the DALITE learning environment. Specifically, we focus our investigation on the relationship between student proficiency, how students change their answers after reading each others' writings, and the peer-votes they earn in DALITE. Key results include: i) peer-votes earned is a significant predictor of success in the course; ii) there are no significant differences between strong and weak students in how often they switch from the correct answer to a wrong answer after consulting peer-rationales, or vice versa; iii) even though males outscore females in conceptual physics questions, females earn as many votes from their peers as males do for the content they produce when justifying their answer choices.

This document contains four papers from a symposium on work ethic and values in human resource development (HRD). "Value Priorities of HRD Scholars and Practitioners" (Reid Bates, Hsin Chih Chen, Tim Hatcher) presents the results of a study that identified and analyzed six HRD values reflecting two value facets (locus of HRD influence and HRD outcomes) and a seventh value reflecting a perceived normative component in all HRD activity. "The Development of a Research Instrument to Compare Working Values across Different Cultures Based on Hofstede's VSM (Value Survey Module) Questionnaire" (Salwa Yousef Al-Sharqawi, Sally Anne Sambrook) discusses an exploratory research approach used to adapt Hofstede's Value Survey Module for use in a doctoral research project examining work values in public and private banks in Kuwait and replicating Hofstede's study of cultural dimensions. "An Examination of the Viability of the Work Ethic Construct" (Sharon S. Naquin, Elwood F. Holton) examines the protestant work ethic (PWE) literature and presents an exploratory and confirmatory factor analysis of leading composite measures of PWE constructs. "Cost Analysis of E-Learning: A Case Study of a University Program" (Tim L. Wentling, Ji-Hye Park) examines cost drivers of e-learning programs and analyzes the University of Illinois' online human resource education program. All four papers include substantial bibliographies. (MN)

This research study provides a comparative understanding of instructional design e-practice in an Australian and an American university. This comparative study identifies information relating to the current status of instructional design e-practice that will be of assistance to Australian universities to improve their existing online programs. The study investigated two universities using a quantitative methodological approach. Participants were students, lecturers and admins of one Faculty in an Australian university and one Faculty in an American university engaged with e-learning programs. The instructional design variables, namely clarifying expectations, personalization, learning scenarios, organizing resources and accuracy of materials were investigated for e-practice. The results showed that there were no significant differences in evaluation of the sub factors between Australian and American students and lecturers. American admins evaluated the sub factors of personalization, organizing resources, and accuracy of materials higher than Australians; however, Australian admins evaluated the sub factor of clarifying expectations higher than the Americans. The evaluations of instructional design practice and its sub factors were above average in general in both countries; however, the sub factor of organizing resources was evaluated as poor in the Australian sample and poor and average in the American sample. This indicates that this sub factor needs to improve in both countries. [For the complete proceedings, see ED579335.]

The concept of physical and chemical change is far from being the clearest and most self-explanatory concept in the world. If a number of chemists are asked to define physical and chemical change, there may well appear to be a fair degree of uniformity in their answers, until a few examples are suggested. When chemists are asked to place a variety of changes into the category of physical or chemical change, then differences inevitably arise. It is not difficult to demonstrate this by viewing school textbooks and articles about the topic. In spite of this, physical and chemical change is still taught in most in most secondary school courses. The problem arises from the definition and the historical layers of meaning that have grown around the concept, almost by accretion, without teachers being aware of their significance. The purpose of this paper is to describe the answers given by experienced educators to a questionnaire, which attempted to find out what the views of science educators/chemists worldwide about physical and chemical change now are. Four appendixes present: (1) List of Respondents; (2) List of Questionnaires Returned; (3) Physical and Chemical Change: An Information Sheet; and (4) Full Questionnaire: Interview Protocol or Basis for Written Response.

Using English as a global communicating tool makes Taiwanese people have to speak in English in diverse international situations. However, consonants and vowels in English are not all effortless for them to articulate. This phonological reduction study explores concepts about phonological (articulating system) approximation. From Taiwanese folks' perspectives, it analyzes phonological type, rate, and their associations with 2 genders. This quantitative research discovers Taiwanese people's vocalization problems and their facilitating solutions by articulating lessening. In other words, this study explains how English emerging as a global language can be adapted and fluently articulated by Taiwanese. It was conducted at National Changhwa University of Education from 2010 fall to 2011 spring, investigating Taiwanese university students' phonological lessening systems. It reveals how they face the phonetics challenges during interactions and give speeches by ways of phonological lessening. Taiwanese folks' lessening patterns belong to simplified pronouncing methods, being evolved through Mandarin, Hakka, and Holo phonetic patterns. This genre of facilitated articulation can be also titled as transformed or approximate methods of articulating formula. In this investigation, 59 students according to their individual articulating experiences provided their perceptions, based on their observations in their own English articulation systems. Statistics graphs analyzed by Statistical Package for the Social Sciences (SPSS) display 4 consonants and 4 vowels that have been reduced and adapted. Moreover, the gender factor was taken into consideration, revealing male's and female's dissimilar difficulties in pronunciation. More specifically, this empirical study investigated the correlation between elements of gender and phonological reduction. Through statistical analysis, 8 intricate vowels and consonants are compared and contrasted based on Taiwanese students' perfections and difficulty-confessions in articulating them. Simplified phonetic patterns with Taiwanese accents involved into the articulating lessening system in Taiwanese students' English utterances were provided by the instructor. Based on 2 variables of female gender and male gender, the study discovered the lessening sequences in 8 phonetics. The significance of this study is its contribution to giving confidence to English speakers in Taiwan. Although they are non-native speakers, they still can resolve the pronunciation difficulty and talk with fluency by their created phonological reduction system. Appended are: (1) Survey (Instrument); and (2) Vowel diversities. (Contains 1 table and 2 graphs.

(Purpose) The purpose of this study was to examine the correlation between certain characteristics of US states and their budgeting systems for higher education (HE), and to derive implications for Japanese HE budgeting policy from the results. (Methodology) The US's State Higher Education Executive Officers (SHEEO) conducted a 30-item questionnaire survey on state higher education budgeting for all 50 states from January to March in 2008 (response rate: 78%). Following general and simple analyses, the following four hypotheses were formed and examined with empirical analyses: (H1) there is a significant correlation between the importance of HE budget in the overall state budget and the adoption of funding formulae; (H2) inflation and fluctuation in enrolment affect whether the funding formula approach or the baseline-incremental approach is selected; (H3) justifications of public financing to the state HE sector are influenced by the cost-sharing status between households and the state government; and (H4) the governors' budget proposal and the legislative passed budget are influenced by certain external factors. (Results) H1 was proved with satisfactory statistical significance. However, H2 showed a result opposite to that originally expected, and H3 could not be proved statistically. These results indicate that the funding formula approach is used more frequently by states which recognize their HE budget as more important comparative to other states and which have experienced greater fluctuations in inflation than the other states over recent years. With regards to H4, the financial burden of households did not affect the justifications selected. Governors' proposals were significantly influenced by the budget volume of primary and secondary education, while legislative passed budgets were largely determined by state unemployment rate. (Conclusions) The results show that funding formulae are in use in more unstable situations and that the decision makers executive and legislative branches do not recognize the importance of the bases of budgeting requests and justifications on the providers' side. (Recommendations) The budgeting system for Japanese national universities is simply dominated by fiscal reform measures, and has much to learn from the strategic decision-making involved in US state HE budgeting systems.

Competitions are used by many teachers at the grass roots level to develop the talents of their gifted students. Each year the top Math, Chemistry, and Physics Olympiad students are identified and assembled into national teams that compete against teams from around the world. This article summarizes findings from the American Olympiad study. Our investigators analyzed data from 345 adult Olympians and found that 52% earned doctorates, and these individuals pursued careers in technical areas that benefit the nation. So far these Olympians have published 8,629 publications, and many of the Olympians have assumed positions in universities or research institutions that contribute to the productivity of the United States. Their success supports competitions as a viable alternative for developing the talents of the gifted. (Contains 1 figure and 6 tables.)

This Delphi study examined what the role of an academic library will be and what skills an academic librarian will need in the year 2005. The study involved two rounds of questions and was conducted between December 1998 and April 1999. Responses were received from 23 experts in 10 countries. In the first round of the study, the experts were asked to answer open-type questions, and the following common issues were identified: (1) impact factors--finance policy, information technology progress, changes in higher education, cooperation/regionalization, and law regulations/public issues; (2) library activities--involvement in teaching/education, information management/access, building collections and making them accessible, managing, creating electronic libraries, cooperation/resource sharing, support for research/reference, and social activities; (3) skills of librarians--communication/training, information technology, managerial, commitment, and subject knowledge/profiling; and (4) problems with new technologies/electronic media--managing electronic information, dealing with change, legal, finance, people, and competitiveness. Based on analysis of first-round results, the second questionnaire was prepared containing 12 closed-type and one open-type question. A vision of the academic library, library activities, and librarians in the year 2005 was formulated. Appendices include: an outline of issues appearing in answers to first-round questions; the second-round questionnaire; and a list of experts surveyed. (MES)

This case study reports on collaborative activities among four fourth grade teachers and their students over a year and explores the effectiveness of distance learning for international team teaching. Two classes in Mexico City conducted school activities with two classes in College Station (Texas). Researchers examined: school activities that successfully bring children of Mexican and Texan cultures together to learn with, about, and from each other; similarities and differences in language skills and pastimes between the children of both cultures; and prevailing impressions Mexican and Texan children had of each other prior to their distance learning activities. Activities were designed to help the students understand each other's cultures by walking in each other's footsteps. The investigation relied on arts-based case study methods. Content analyses were conducted of lesson plans and observations, students' poems about the other nation, students' stories about a day in the life of a child in the other culture, student questionnaires, students' collages, and student self-profiles. Mexican children had enough experience of U.S. culture to accurately describe it in poetry. Most Texan children had little knowledge of Mexico and had to write about their own culture, create an imaginary place, or refer to stereotypes in order to create a poem. (Author/ MES)

This pilot study was conducted with a sample of 25 female administrators. Fourteen of the participants are employed in Alabama public schools, while seven work in international schools in the United States, and the remaining four are administrators in international schools in Mexico. The international schools in the study are listed in the "ISS (International School Services) Directory of Overseas Schools." It examines the perceptions that female administrators have in relation to the barriers confronting them in striving for upward mobility. A Cronbach's alpha analysis was used to determine the reliability of the instrument. In addition, a principal components analysis with a varimax rotation was performed. This identified four factors, which are described as: (1) support systems barriers; (2) social barriers; (3) self-imposed barriers; and (4) cultural barriers. (Contains 4 tables and 69 references.)

This study examined the psychometric characteristics of a 62-item parenting questionnaire completed by parents from the United States, Australia, China, and Russia. Factor analyses yielded three global parenting dimensions for each culture which were consistent with D. Baumrind's (1971) authoritative, authoritarian, and permissive typologies. The global parenting dimensions were subsequently analyzed to assess their internal structures. For each of the three global dimensions, a number of specific parenting practice factors were identified and compared cross-culturally. The internal factors for the authoritative style were: (1) warmth and involvement; (2) reasoning/induction; (3) democratic participation; and (4) good natured/easy going. The factors for the authoritarian style were: (1) verbal hostility; (2) corporal punishment; (3) non-reasoning, punitive strategies; and (4) directiveness. The factors for the permissive style were: (1) follow through; (2) ignoring misbehavior; (3) and self-confidence. Quite similar parenting practice factors were found for authoritative parenting across cultures; for authoritarian and permissive styles there were substantial cross-cultural differences among the specific parenting practices. Factor scores of the global parenting styles and specific practices were correlated with preschool behavioral problem outcomes to assess the validity of the instrument's cross-cultural use. For the United States and Australian families, mother and father authoritativeness and authoritarianism were related to child preschool behavioral problem outcomes. (KDFB)

In this study, a questionnaire was designed to assess Montessori teachers' reported likelihood of intervention in some 25 common situations in Montessori classrooms for 3-6 year olds, as well as to obtain limited background information on the teachers. Subjects were 422 Montessori teachers including 30 from Trinidad (where the questionnaire was first designed and field tested), 9 from Haiti, 362 from the United States, and 21 from Canada. Care was taken to ensure that each of the major Montessori teacher training organizations was represented in the sample. The primary research question to be answered was whether or not Montessori teachers say that they intervene in children's use of materials that require seriation or classification. Additional questions examined reported likelihood of intervention in fantasy play, math errors, language errors, general errors of fact, disruption, and dangerous activities. Findings showed that in the area of seriation and classification activities, Montessori teachers are quite consistent in reporting that they are not likely to intervene, while in the area of math and language, teachers are more likely to respond to errors. In the area of fantasy play results show that Montessori teachers are much more variable in their responses. While this could indicate that Montessori teachers are working to individualize their responses to each child in each situation, in fact it probably means that many teachers are uncertain how to respond to fantasy play in the Montessori classroom.

A study examined teachers' actual use of media and pictures in their teaching of geography in the secondary schools of five countries (a previous study focused on representations). About 180 teachers from Australia, Greece, Japan, Sweden, and the United States responded to a questionnaire concerning how often they used various types of media or equipment, what kinds of pictures they used, and the reasons for using the pictures. Results indicated that: (1) there was a substantial difference in media use by individual teachers; (2) the blackboard and geography textbooks were used often by teachers in most countries; (3) wall maps are most used in Japan, used weekly in Australia, Sweden, and the United States, and monthly in Greece; and (4) geographical or print media was used much more than audio-visual media. Findings suggest that geography teaching is still very much an oral activity with very little media support. (Six tables of data are included; the questionnaire is attached.) (RS)
