Evaluation of a randomized intervention to delay sexual initiation among fifth-graders followed through the sixth grade

US adolescents initiate sex at increasingly younger ages, yet few pregnancy prevention interventions for children as young as 10-12 years old have been evaluated. Sixteen Washington, DC schools were randomly assigned to intervention versus control conditions. Beginning in 2001/02 with fifth-grade students and continuing during the sixth grade, students completed pre-intervention and post-intervention surveys each school year. Each year, the intervention included 10-13 classroom sessions related to delaying sexual initiation. Linear hierarchical models compared outcome changes between intervention and control groups by gender over time. Results show the intervention significantly decreased a rise over time in the anticipation of having sex in the next 12 months among intervention boys versus control boys, but it had no other outcome effects. Among girls, the intervention had no significant outcome effects. One exception is that for both genders, compared with control students, intervention students increased their pubertal knowledge. In conclusion, a school-based curriculum to delay sexual involvement among fifth-grade and sixth-grade high-risk youths had limited impact. Additional research is necessary to outline effective interventions, and more intensive, comprehensive interventions may be required to counteract adverse circumstances in students' lives and pervasive influences toward early sex.ClinicalTrials. gov identifier: NCT00341471.     

Creating an information-rich learning environment to enhance design student learning: challenges and approaches

The use of technology with engineering design students is well established, with shared workspaces being particularly supportive of the collaborative design process. This paper reports on a study where a design knowledge framework involving three learning loops was used to analyse the effectiveness of shared workspaces and digital repositories in supporting design education. The issues discussed include the relationship between knowledge and information structures, the importance of integrating information literacy support, and the need for different systems within the learning environment to support formal and informal storage of resources. These issues are explored within the context of experiences of working in a multidisciplinary team with different approaches, research methodologies, and discourses.     

Sexual abuse and suicidality: gender differences in a large community sample of adolescents

OBJECTIVE: A cross-sectional study of gender specific relationships between self-reported child sexual abuse and suicidality in a community sample of adolescents. METHOD: Students aged 14 years on average (N = 2,485) from 27 schools in South Australia completed a questionnaire including items on sexual abuse and suicidality, and measures of depression (Centre for Epidemiological Studies Depression Scale), hopelessness (Beck Hopelessness Scale), and family functioning (McMaster Family Assessment Device General Functioning Subscale). Data analysis included logistic regression. RESULTS: In boys, self-report sexual abuse is strongly and independently associated with suicidal thoughts, plans, threats, deliberate self-injury, and suicide attempts, after controlling for current levels of depression, hopelessness, and family dysfunction. In girls, the relationship between sexual abuse and suicidality is mediated fully by depression, hopelessness, and family dysfunction. Girls who report current high distress about sexual abuse, however, have a threefold increased risk of suicidal thoughts and plans, compared to non-abused girls. Boys who report current high distress about sexual abuse have 10-fold increased risk for suicidal plans and threats, and 15-fold increased risk for suicide attempts, compared to non-abused boys. Fifty-five percent (n = 15) of sexually abused boys attempted suicide versus 29% (n = 17) girls. CONCLUSIONS: A history of sexual abuse should alert clinicians, professionals and carers in contact with adolescents, to greatly increased risks of suicidal behavior and attempts in boys, even in the absence of depression and hopelessness. Distress following sexual abuse, along with depression and hopelessness indicate increased risk of suicidal behavior in girls, as well as boys.     

Constraints to UPE: More than a question of supply?

The traditional approach to universal primary education (UPE) in developing countries has emphasised supply factors of schooling systems, such as the construction of schools and teacher training facilities, revisions to curricula and improvements in teaching materials. No doubt all these factors have played an important part in encouraging the growth of enrolment ratios throughout the developing world during the past two decades. But the profile of absentees from school, and the disproportionate enrolment of boys and girls in school suggest that this approach is unlikely to achieve full UPE. This paper calls for consideration of demand factors which may prevent children from attending school. Focusing on the household as the relevant unit, it examines the costs incurred when a child attends school in the developing world, and the benefits to be gained from school attendance. The paper then goes on to consider the case of Botswana, where, within the context of the goal of UPE, the government is investing vast resources in the expansion and improvement of the primary school system. Yet substantial numbers of children, boys in particular, continue to be withheld from school. After an analysis of the demand factors which prevent children from attending school in rural Botswana, the paper concludes with a discussion of the additional policies the Botswana government might find necessary to employ in order to achieve full UPE.     

Science Teachers’ Misconceptions in Science and Engineering Distinctions: Reflections on Modern Research Examples

The aim of this exploratory study was to learn about the misconceptions that may arise for elementary and high school science teachers in their reflections on science and engineering practice. Using readings and videos of real science and engineering work, teachers’ reflections were used to uncover the underpinnings of their understandings. This knowledge ultimately provides information about supporting professional development (PD) for science teachers’ knowledge of engineering. Six science teachers (two elementary and four high school teachers) participated in the study as part of an online PD experience. Cunningham and Carlsen’s (Journal of Science Teacher Education 25:197–210, 2014) relative emphases of science and engineering practices were used to frame the design of PD activities and the analyses of teachers’ views. Analyses suggest misconceptions within the eight practices of science and engineering from the US Next Generation Science Standards in four areas. These are that: (1) the nature of the practices in both science and engineering research is determined by the long-term implications of the research regardless of the nature of the immediate work, (2) engineering and science are hierarchical, (3) creativity is inappropriate, and (4) research outcomes cannot be processes. We discuss the nature of these understandings among participants and the implications for engineering education PD for science teachers.     

Web-based learning: Challenges in using the Internet in the undergraduate curriculum.

Often compared to Gutenberg's introduction of the printing press in the 1450s, the use of the Internet in education, and especially within the undergraduate curriculum is ubiquitous. Yet the development and presentation of electronic undergraduate curriculum specifically on the Internet is a relatively new venture. Although guidelines for course development are emerging as quickly as the technology is introduced, several problems associated with i) style (appropriateness and effectiveness), ii) process (mechanistic and communication based), and iii) edited content of relevant information, continue to exist in the typical undergraduate applications. This paper describes the development of electronic curriculum in two undergraduate courses. The courses were an Introduction to Quantitative Methods, and an Introduction to Epidemiology; both of which typically use computers and as such, the introduction of advanced technology was not expected to have been an issue. In addition to the successes and shortcomings experienced in the presentation of these courses, the paper discusses an underlying theoretical framework upon which the development of the Internet components of the courses were based.     

Rats’ responses to molar and local schedule constraints

Three experiments explored responses to molar and local schedule constraints. Thirsty rats pressed a lever for access to a water spout. In Experiment 1, response totals were unaffected by two local schedule characteristics—the variability of the instrumental requirement and the variability of the magnitude of contingent reward. Experiment 2 manipulated the correlation between the instrumental requirement and the magnitude of reward. This correlation did not affect the behavioral price ratio (presses per lick) at a molar level. At a local level, the positive correlation created a lower mean lick price than did the negative correlation. The rats licked more, and licked less efficiently, under the positive correlation than under the negative correlation. Experiment 3 compared two ways of manipulating the molar presses/lick ratio: The instrumental (contingent) series varied the instrumental (contingent) requirement, but held the other requirement constant. As the ratio increased, total leverpresses increased, and total licks decreased linearly; the two series did not differ significantly. At higher lick prices, the rats licked more efficiently and made more extra licks at the spout as it closed. The results help delimit the applicability of molar models of the organism’s response to schedule constraints.     

Information Technology in Public Libraries in Kuwait: A First Study

This study examines the availability and use of information technology in public libraries in Kuwait. Specific areas addressed are (1) hardware/software, (2) patterns of connectivity such as LANs, Internet, etc., (3) training and development activities in support of information technology, and (4) future projections regarding the use of information technology. The study provides policy-makers and information professionals with previously unavailable baseline data concerning the use of computers and access to telecommunications networks in public libraries in Kuwait. A questionnaire sent to all public libraries (N=25) yielded a 92% response. Interviews with libraries' administrators and authorities were also undertaken to gather additional data. The results of the study reveal that many information technology inequalities exist among the libraries. Only eight libraries make use of computers and 15 are without any type of IT-related technology. The study shows that few libraries have connectivity, limited use of applications, and the implementation of an automated library system are slow moving. Factors impeding the development of information technology are planning, funding, human resources, and building structure. Recommendations are made with the intention to encourage the public library sector and information professionals in Kuwait to take a proactive position in overcoming the forces that hinder the development of IT.     

A Theoretical and Empirical Exploration of Intrinsic Problems in Designing Inquiry Activities

A central concern in science education is promoting inquiry activities, and a significant amount of research in science education has addressed what inhibits this goal. However, this research has tended to be focused on implementation issues. Levels of implementation are correlated with extrinsic barriers such as time, resources and teacher knowledge, but the internal structure of inquiry remains unexamined. However, are there also some ways in which inquiry based instruction is intrinsically difficult? That is, given perfect conditions for implementation, is devising inquiry activities a non-trivial matter, and are there patterns to the difficulties in doing so? The aim of this paper is to provide both a theoretical and empirical basis for the intrinsic problems associated with the construction of inquiry activities. We present a theoretical framework that connects contemporary studies of science to the classroom context. We then examine a case study of teacher education students designing inquiry-based instruction to demonstrate empirical evidence of intrinsic problems. Our ultimate goal is to improve our ability as teacher educators to guide science teachers in fulfilling this central task of their work.
