Dynamische Probleml?sekompetenz

This article is about the importance and validity of dynamic problem solving (DPS) in predicting technical problem solving performances. In addition to DPS, fluid intelligence and technical knowledge were included in the study. Assessing DPS and fluid intelligence simultaneously also allowed for testing the empirical distinction between both constructs. Results are based on data of a sample of car mechatronics (n?=?129) and electronics technicians (n?=?88) and showed that DPS and fluid intelligence were empirically separable. In the first sample (electronics technicians) DPS explained technical problem solving performance best, although fluid intelligence showed incremental validity too. In the second sample (car mechatronics) fluid intelligence was weakly related to the criterion whereas DPS was not at all. When technical knowledge was added to the prediction, both DPS and fluid intelligence did not predict technical problem solving performance. However, in the sample of the electronics technicians fluid intelligence indirectly affected the criterion through technical knowledge. A discussion of the somewhat contradictory results, the different results patterns in the two samples and a theoretical explanation of the results are provided.     

The Power of Expectation

Abstract In 1999, the first author and his colleagues at the Smithsonian Institution published an article in Curator: The Museum Journal introducing research on the experiences visitors find satisfying in museums. Subsequent data collection has expanded on these findings, as this Research Note will elucidate. In general, the team found that experiences that visitors were looking forward to on entrance tended to have a distribution similar to that of the experiences they found satisfying on exit. The aim of this note is to present data that demonstrates this consistency, and to observe that visitors’ expectations that they would have certain types of experiences upon entering a museum or exhibition were a much larger factor in determining their responses than were minor differences in museum or exhibition content or presentation. In other words, on the whole they came in knowing what experiences they expected, and they left having found them, regardless of what museum personnel presented to them inside.     

Philosophy and Ethics in Western Australian Secondary Schools

Abstract

The introduction of Philosophy and Ethics to the Western Australian Certificate of Education courses in 2008 brought philosophy into the Western Australian secondary school curriculum for the first time. How philosophy came to be included is part of a larger story about the commitment and perseverance of a relatively small number of Australian educators and their belief in the value of introducing philosophical communities of inquiry into school classrooms through a revised pedagogy which could sit comfortably with an outcomes-based education system.     

Religious socialization of youth involved in child welfare

Increased religiosity is associated with a variety of improved outcomes, especially for youth in disadvantaged contexts. Although youth involved in child welfare may experience protective effects of religious participation or values, little is known about the impact of maltreatment on religious development. Using the National Survey of Child and Adolescent Well-Being, a nationally representative study of child welfare involved families, correlates of religious attendance and importance of religion for youth were investigated using weighted logistic regression at two waves 18 months apart. Youth self-reports of religious attendance and their ratings of its importance were associated with religious attendance of their caregivers, whether birth-parents or foster parents. Foster parents were more likely to attend religious services than birth parents. Increases in youth attendance from Wave 1 to Wave 2 were associated with high youth religious importance at Wave 1, whereas decreases in attendance were associated with moving between home and foster placements. Increases in religious importance from Wave 1 to Wave 2 were associated with religious attendance at Wave 1 and with the youth being Black.     

Information management and learning in computer conferences: Coping with irrelevant and unconnected messages

The present study examines how learnersinteract with one another within the context ofa computer conference for the purposes ofpassing a test. In a faked computer conferencewith predetermined messages, both the number ofmessages irrelevant to the topic, and theexplicit threading of messages were varied in a2 × 2 design (n = 54). Subjects participated in anasynchronous fashion over a course of fourlog-in sessions. In general, learners indicateda fairly consistent pattern of reception. Theyopened virtually all messages, grouped them ina non-chronological order, and processed themaccording to their topic relevance. Thispattern was also mediated by the conferencecharacteristics. Explicit threading led tosequences of message readings that were morecontent oriented. Similarly, fewer irrelevantmessages lead to prolonged reading times ofrelevant messages. Whereas learning success wasnot affected by conference characteristics,explicitly threaded messages decreased theperceived cognitive demands.

Academic growth trajectories of ELLs in NAEP data: The case of fourth- and eighth-grade ELLs and non-ELLs on mathematics and reading tests

Utilizing the National Assessment of Educational Progress (NAEP) data, this study examined (1) how fourth and eighth-grade ELLs' mathematics and reading scores on national tests compared to their non-ELL peers' scores over the testing period between 2003 and 2011, and (2) if gender and ethnicity contributed to variation in the growth patterns among the student groups across grade levels and content areas. Since the NAEP data, which provides a national sample of 10,000–20,000 students, is collected using a probability sample design, sampling weights are adjusted so inferences can be appropriately made. Sample sizes within NAEP are large enough to generate adequate power for statistical significance. Thus, to display the data in a multivariate mode, Tableau 8.0.0 software was used. Results suggested that the achievement gap between non-ELLs and ELLs is either steady or slightly widening in both mathematics and reading, with multiple paths across the content areas, grade levels, and gender and ethnic groups.     

Learning from scientific texts: personalizing the text increases transfer performance and task involvement

In an experiment with 65 high-school students, we tested the hypothesis that personalizing learning materials would increase students’ learning performance and motivation to study the learning materials. Students studied either a 915-word standard text on the anatomy and functionality of the human eye or a personalized version of the same text in which 60 definite articles (e.g., “the eye”) were replaced with 60 second-person possessive pronouns (e.g., “your eye”). Afterwards, participants answered comprehension and transfer questions. One week later, the participants were asked to restudy the text and to answer the same questions again with the aim to improve their performance. In the personalized text condition, students showed higher transfer performance, spent more time on restudying the text, and reported being more motivated than students in the standard text condition. However, only duration of restudying (not self-reported motivation) mediated the effect of personalization on transfer performance.
