This paper describes the development of a new measure of attitude towards science for use among secondary school pupils which operationalises the affective attitudinal domain. Item selection, the internal structure and reliability of the scale, content validity and construct validity were established on a sample of 2129 pupils in the third, fourth, fifth and lower sixth years of Protestant and Catholic grammar schools in Northern Ireland. Scale norms demonstrate that males record a more positive attitude towards science than females, and that younger pupils record a more positive attitude towards science than older pupils.  相似文献

The present study examined the development of morphological awareness and its contribution to vocabulary and reading comprehension among young Chinese-speaking English language learners (ELLs). We focused on two aspects of morphological awareness: derivational awareness and compound awareness. Participants included 46 kindergarteners (younger cohort) and 34 first graders (older cohort) of Chinese descent in Canada at the beginning of the study. Children were administered a battery of English measures including derivational awareness, compound awareness, phonological awareness, receptive vocabulary, and reading comprehension at two time points spaced 1?year apart. Results demonstrated a steady growth in Chinese-speaking ELL children??s derivational and compound awareness from kindergarten to Grade 2. Importantly, for the first graders, morphological awareness accounted for unique variance in vocabulary concurrently, and unique variance in both vocabulary and reading comprehension a year later. Generally speaking, the variance explained by morphological awareness increased with grade level, and derivational awareness accounted for more variance in vocabulary and reading comprehension than did compound awareness. These results underscore the emerging importance of morphological awareness, especially derivational awareness, in young Chinese-speaking ELL children??s English reading development.  相似文献

A central concern of persons in HIV education and prevention is whether a person testing positive tells sexual partners of this result. An accumulation of 51 studies across twenty years reveals that 40% of persons testing positive for HIV antibodies did not reveal this result to sexual partners (5287/8854). The impact of various factors (age, gender, date of the study, time since diagnosis, nature of the diagnosis, and sexual orientation) received consideration.  相似文献

The purpose of this study was to examine the impact demographic variables of gender and sales experience have on the performance of business‐to‐business (B2B) sales professionals. If a deeper understanding can be established of how gender and sales experience variables relate to B2B sales performance, human resource development (HRD) and human performance improvement (HPI) professionals can use these indicators during the hiring and selection process. This article reports findings of the study and offers implications to the field of HRD and HPI.  相似文献

Idiomatic communication is a strategic and unique form of communication that is indicative of a close relationship. The purpose of this study was to investigate the relationship between idiomatic communication with solidarity and satisfaction to validate Social Penetration Theory using Knapp's stages of escalation and de-escalation. The results of the study (N = 275) found that couples in de-escalation stages report less idioms, and use idioms with less frequency, than couples in the escalation stages. Couples in de-escalating stages use confrontation, nickname, and teasing insult idioms with more negative effects than escalating couples. Finally, the use of idiomatic communication is significantly related to solidarity and relational satisfaction.  相似文献

The purpose of this research was to determine whether or not a hypothesized Institutional orientation existed as a a learner orientation distinct from those previously identified by Houle (Goal, Activity, Learning) and Burgess (Religious). And if it exists, to what extent it played a significant role in determining the participatory behaviour of adult learners in three different adult education institutions (local church, community college, Red Cross). The data obtained from the 30‐item composite instrument (Reasons for participation in learning activities) were submitted to a one‐way ANOVA, the Scheffe‘t‐test and chi‐square analysis. The results indicated that the Institutional orientation does exist as a distinct adult learner orientation. Chi‐square analysis of the data indicated that the church‐sponsored group was significantly different from the other two groups in the degree to which the Institutional orientation of the adults affected participation, and in the reported degree of commitment to the sponsoring institution, as well as the reported frequency of attendance at educational activities sponsored by the institution. It was concluded that the Institutional orientation does play a significant role among some adult participants. Further, that sociological aspects of the study of adult participation need to be considered if we are to understand fully all of the dynamics at work that precipitate and sustain participation in voluntary educational activities.  相似文献

Pupil discomfort in sex education lessons is high, often manifesting itself in reluctance to participate constructively. Low levels of participation are problematic, jeopardizing effective learning. Teacher interview and lesson observation data, collected in 25 schools in the East of Scotland, reveal that there is much variation between classes with regard to pupils' participation. Class size and composition (e.g. in terms of sex, ability, maturity and age), pupils' interest in sexual health matters, the teacher's relationship with the class (e.g. in terms of teacher humour and discipline), the materials used, the time of the lesson, and the school catchment were all identified as important factors. Classes with the highest level of participation tended to be comprised predominantly of girls, were older, were headed by a teacher with a strong sense of humour and a tight disciplining style and who was new to the class that year, used material which the pupils appeared to find interesting and made use of methods with which they were comfortable, and were in schools with a mixed catchment.  相似文献

Situated at the intersection between child-led visual methods and sex education, this paper focuses on the potential of youth-led video making to enable young people to develop guiding principles to inform their own sexual behaviour. It draws on findings from a video-making project carried out with a group of South African young people, which engaged them in identifying and tackling critical issues of HIV and AIDS. By analysing one of the youth-generated videos using critical visual analysis, we conclude that youth-led video making can be an effective tool to allow young people to talk about their interests and concerns and to develop guiding principles for their own sexual behaviour. This tool is especially relevant to young people whose needs are not being met by the current sexual health curriculum and can be a fun medium through which to engage participants in ensuring that sex education needs are met.  相似文献

Foodborne illnesses remain a common problem in the United States. Focus group results indicated that lack of knowledge and improper handling of leftovers were common among food preparers in families with young children. The USDA‐recommended storage time for leftovers was used to develop and conduct a food safety social marketing campaign, 4 Day Throw Away using both traditional and social media. A procedural model for developing a theory‐based nutrition education intervention and the Health Belief Model were used to design, implement, and evaluate this campaign. The #4 mascot made numerous public appearances (in person and TV) to convey the 4 Day Throw Away message; 10000 magnets were distributed; and 500 posters with tear‐off note card were posted in the traditional campaign. Magnets and note card directed recipients to a website (4984 visits) with food safety information about leftovers. The social media campaign included 4 YouTube videos (11759 views); a Facebook page (166 users with over 21240 post views); and 51 followers on Twitter. The use of multiple media channels increased awareness and intention to change health behaviors especially among parents of children 10 and younger. Both traditional and social media methods in the 4 Day Throw Away campaign reached the intended audience suggesting that interventions using a mix of media channels broaden the reach and potential for intended behavior change.  相似文献
