Urban High School Students’ IT/STEM Learning: Findings from a Collaborative Inquiry- and Design-Based Afterschool Program

This exploratory study examines the impact of a collaborative inquiry- and design-based afterschool program on urban high school students’ IT/STEM learning—using information technology (IT) within the context of science, technology, engineering, and mathematics (STEM). The study used a mixed methods design, involving 77 participants within two cohort groups, each participating in an eighteen-month intervention period. Data were collected from the pre- and post-surveys, analysis of the participants’ IT/STEM projects, external evaluation reports, and follow-up interviews. Findings indicate that the program had a significant impact on students’ technology and IT/STEM skills, frequency of technology use, and understanding of IT use in STEM-oriented fields. Some degree of impact on attitude changes toward IT/STEM and career aspirations in these fields was also in evidence. The study demonstrates that IT/STEM experiences supported through technology-enhanced, inquiry- and design-based collaborative learning strategies have significant impact on urban high school students’ IT/STEM learning. Effect of afterschool programs on attitude changes and IT/STEM-related career aspirations of urban high school students are recommended areas of further investigation.     

Using meta-reflection to improve learning and throughput: redesigning assessment procedures in a political science course on power

The aim of this article is to contribute to the discussion on how examinations can be designed to enhance students’ learning and increase throughput in terms of the number of students who sit, and pass, the course examination. The context of the study is a basic level political science course on power analysis, which initially suffered from low throughput. The contribution of the article is to demonstrate that no other changes to the course than the introduction of an element of meta-reflection in the take-home examination – a so-called ‘reflection exercise’ – helped increase throughput by 70–80%. The aggregated performance of the students was thus significantly enhanced after they were explicitly encouraged to meta-reflect on problems posed in the take-home examination, and on different strategies for tackling these problems. The introduction of another meta-reflection exercise in the mandatory seminars did not further increase throughput, but made a qualitative difference in terms of the positive feedback that students received on their work.     

PBL and CDIO: complementary models for engineering education development

This paper compares two models for reforming engineering education, problem/project-based learning (PBL), and conceive–design–implement–operate (CDIO), identifying and explaining similarities and differences. PBL and CDIO are defined and contrasted in terms of their history, community, definitions, curriculum design, relation to disciplines, engineering projects, and change strategy. The structured comparison is intended as an introduction for learning about any of these models. It also invites reflection to support the understanding and evolution of PBL and CDIO, and indicates specifically what the communities can learn from each other. It is noted that while the two approaches share many underlying values, they only partially overlap as strategies for educational reform. The conclusions are that practitioners have much to learn from each other's experiences through a dialogue between the communities, and that PBL and CDIO can play compatible and mutually reinforcing roles, and thus can be fruitfully combined to reform engineering education.     

The impact of reading material’s lexical accessibility on text fading effects in children’s reading performance

The acceleration phenomenon (AP) is defined by improvements in reading speed and reading comprehension, induced by an artificial text fading procedure corresponding to the previously determined fastest individual reading rate. Recent results, however, indicated that fading that is slower than the self-paced reading rate can produce comparable reading enhancements. As reading performance can be strongly influenced by the reading material, this study aimed at investigating to which extent reading enhancements induced by text fading depend on the reading material’s characteristics. We confronted 39 German third graders with a previously utilized text fading procedure, which was slower than their self-paced reading rate. Included text varied regarding to the lexical accessibility (LA), representing how well information can be accessed from the mental lexicon. Children’s reading rates increased statistically significant due to text fading for all LA levels. However, reading comprehension was sensitive to the text material’s characteristics: Reading comprehension enhancements were observable for easily accessible reading material, but not for material with intermediate or difficult levels of LA. Material that was difficult to retrieve from the mental lexicon even resulted in reduced reading comprehension in the fading condition. Possible influences on immediate lexical access, the impact of working memory capacity and implications for future AP research are discussed.     

Trivializing the News? Affective Context Effects of Commercials on the Perception of Television News

This study examined whether affect induced by television commercials influences the perception of news programming. An experiment showed that viewers in positive moods generated by television commercials perceive news stories viewed both after and before watching the commercials as more entertaining, relaxing, realistic, and more credible than viewers exposed to neutral commercials do. Of interest, viewers in positive mood, as compared to neutral mood, perceived the topic presented in the news story as less important and serious.
