Investigating the Influence of Motivational Factors on Conceptual Change in a Digital Learning Context Using the Dual‐Situated Learning Model

This study examines the relationship between the learning motivation and conceptual change of 127 eighth graders, after they have learned the acid, base, and salt concept in a digital learning context, designed according to the dual‐situated learning model (DSLM). Two instruments—the students’ motivation towards science learning (SMTSL) questionnaire and the acid‐base‐salt concept diagnostic test (CDT)—were used in the study. The questionnaire and the test were given to students in pre‐test, post‐test, and delayed post‐test. Based on their motivation questionnaire scores, 18 students were selected from various scoring ranges for semi‐structural interviews. Results showed that, after experiencing DSLM digital learning, students’ post‐CDT and delay‐CDT scores were significantly higher than pre‐CDT scores (p < 0.001, p < 0.01). Furthermore, Pearson correlation analysis indicated that students’ conceptual change (ΔCDT) was significantly correlated with motivational factors such as self‐efficacy (SE), active learning strategy (ALS), science learning value (SLV), achievement goal (AG), and learning environment stimulation (LES) (p < 0.05). Interviews also supported students’ motivational correlation to ΔCDT, particularly for SE, ALS, and AG.     

考研要花多长时间准备

刚动了考研念头的低年级同学对考研的整个过程和细节十分模糊,他们更多的是一种愿望,冲劲.由于对细节的认识不清楚,同学们经常会提一些不好回答的问题,最经常的在bbs上看到的是这样一条:各位大虾,我是一名刚上大学的新生,我想毕业时考研究生,但对此一无所知(或说知甚少),谁能给我一些建议吗(或谁能给我指点迷津)?     

Using the results of a satisfaction survey to demonstrate the impact of a new library service model

Background: In 2005, the University of Calgary entered into a contract to provide library services to the staff and physicians of Alberta Health Services Calgary Zone (AHS CZ), creating the Health Information Network Calgary (HINC). Objectives: A user satisfaction survey was contractually required to determine whether the new library service model created through the agreement with the University of Calgary was successful. Our additional objective was to determine whether information and resources provided through the HINC were making an impact on patient care. Methods: A user satisfaction survey of 18 questions was created in collaboration with AHS CZ contract partners and distributed using the snowball or convenience sample method. Results: Six hundred and ninety-four surveys were returned. Of respondents, 75% use the HINC library services. More importantly, 43% of respondents indicated that search results provided by library staff had a direct impact on patient care decisions. Conclusions: Alberta Health Services Calgary Zone staff are satisfied with the new service delivery model, they are taking advantage of the services offered, and using library provided information to improve patient care.     

Television news is government news in Taiwan patterns of television news sources selection and presentation

Based on a content analysis of evening newscasts by the three television stations in Taiwan, this study examines the patterns of news sources selection and presentation in television news. The results of this study show that television news relies heavily on government officials who are primarily middle‐aged men in executive positions located in the capital city of Taipei. These findings suggest that the central government officials in Taipei appear to be the primary definers of social reality. TV news portrays only a very limited view of the society. In conclusion, this study suggests that with the management and content tightly controlled by the state, Taiwan's television news consists primarily of official rituals.     

Editorial

Twelve focus groups were conducted with African-American and Latino youth (age 14-19) in Washington, DC to inform the development of a program to postpone sexual involvement among younger teens (age 12-14). The study's objectives were to uncover the prime motivators for early sexual involvement, examine attitudes towards pregnancy and contraception, explore peer and family influences on sexual decision-making, and identify the youth's preferred sources of information and advice on sexual matters. The data suggest that sex is a peer norm for these youth and generally begins by age 15 or before. The prime motivator for early sex among the young women appears to be social pressures from boyfriends, peers and even older siblings. In contrast, young men seem to be more motivated by physical desire, and draw a clear distinction between relationships that are exclusively sexual and those that are more serious and romantic. Early pregnancy was universally viewed as undesirable, but not always as a hindrance to one's future. While motivation to avoid pregnancy appears to be less pronounced among the African-American youth, potential barriers to contraceptive use seem prominent in both groups due to strong negative opinions about the safety and efficacy of various methods. Condoms are viewed as being appropriate for casual sexual encounters, but not for longer, more established relationships. Parents received mixed reviews as sources of information and guidance on sexual matters. Latino youth were more likely than African-Americans to view parents as being influential in their sexual decision-making, but appear less likely to rely on them for information and advice. All youth preferred clinics to schools for sex education and related services. Overall, these data signal the need for interventions that generate peer support for delaying sex and pregnancy, correct misinformation about contraceptives, and encourage frank, open discussions between youth and their parents or other caring adults.     

GROWING AS TEACHER EDUCATORS: Learning New Professional Development Practices

This article examines the ways that, in Holocaust education in Jewish schools in Melbourne and New York at the beginning of the 21st century, knowledge of the Holocaust is transferred to students in chronological form. It begins by asking: What work do chronological narratives do within the Holocaust historical narratives offered within Jewish high school classrooms? In order to explore this question, examples from curricula and interviews with the teachers are explored. It is argued that while the use of chronological narratives within the high-school classroom to narrate historical events is not unique to the teaching of the Holocaust, the work which this narrative form does is particular to the negotiation of the traumatic aftermath of the Holocaust.     

Dump-and-Chase: The Effectiveness of Persistence as a Sequential Request Compliance-Gaining Strategy

Two field experiments were performed assessing the effectiveness of the dump-and-chase, a compliance-gaining technique employing strategic persistence. These two experiments demonstrate the effectiveness of the dump-and-chase relative to other known compliance-gaining techniques. Experiment 1 found the dump-and-chase more effective than pooled data from the door-in-the-face and placebic information technique. Experiment 2 found the dump-and-chase more effective than the door-in-the-face, placebic information, and foot-in-the-door. The dump-and-chase produced consistently higher compliance-gaining proportions across experiments. Moreover, because the contextual features of two experiments differed substantially, the effect was robust to important contextual differences.     

Interpreting relational meanings: The influence of sex and gender‐role

This study addresses three types of sex differences in relational communication. Male and female respondents completed an assessment of gender‐role measuring agency and communion and read four scenarios with messages attributed to male and female sources. Respondents rated the relational dimensions of affiliation and dominance. Female sources are judged higher in affiliation. Sex and agency interact with situation for perceptions of affiliation. Situation and communion affect judgments of dominance. Individuals higher in communion perceive less dominance. The results provide insight into dominance and affiliation as competing frames for interpreting situations.     

Differences in the Scientific Epistemological Views of Undergraduate Students

The purpose of this study was to examine whether science and non‐science major students have different scientific epistemological views (SEVs). A multidimensional instrument previously developed by the authors was used to assess differences in college students’ SEV of various aspects. A total of 220 freshmen (42% science and 58% non‐science majors) attending two public universities participated in this investigation. Results indicated that the science majors have less sophisticated beliefs in the theory‐laden and cultural‐dependent aspects of science than non‐science majors. Analysis of variance results further revealed significant differences in SEV dimensions among the three major fields: non‐science, pure science, and science education. Science education students gained the lowest scores on the entire scale among the groups. Findings of this study imply that science major (including science education) students might be involved longer in such an epistemic environment that described scientific knowledge as objective and universal. It is also possible that beliefs about certainty and objectivity lead these students to select science as their major field. Implications for future research and science teacher education are discussed.
