Change in Fluid and Crystallized Intelligence and Student Achievement: The Role of Intellectual Engagement

Intellectual engagement (IE) refers to enjoyment of intellectual activities and is proposed as causal for knowledge acquisition. The role of IE for cognitive development was examined utilizing 2‐year longitudinal data from 112 ninth graders (average baseline age: 14.7 years). Higher baseline IE predicted higher baseline crystallized ability but not changes therein, and was not associated with fluid ability. Furthermore, IE predicted change in school grades in language but not in mathematics grades or in standardized tests. These findings suggest that IE is not a major predictor of knowledge acquisition in adolescence, where degree of self‐determination in intellectual behaviors may be relatively limited. Open questions for future research are addressed, including reciprocal longitudinal associations between IE and academic and cognitive development.     

PREFERENCES AND ASSESSMENT OF MATHEMATICALLY HIGHLY ABLE YOUNG STUDENTS

Giftedness is commonly regarded as potential for extraordinary performance within a given area, e.g. academic, artistic, or manual, that develops in a field of interacting internal and external factors and unfolds in individual stages. Gender related and culturally dependent influences affect the dynamic processes through which a child acquires and expands its competence. Admittedly, a particular talent for a special intellectual activity, e.g. mathematics and sciences, is essential, but such a talent alone is not necessarily sufficient to explain why young students devote themselves to particular subject matter, thereby acquiring a high level of ability.

     

Alternative assessment of knee joint muscle balance of soccer players through total work-based hamstring: quadriceps ratios

Isokinetic hamstring-to-quadriceps (H:Q) ratios are frequently used to assess knee muscle strength imbalances and risk of injuries/re-injuries. The use of peak torque (PT) or total work (TW) to estimate joint stability may lead to different results because of the differences between these two neuromuscular variables. Thus, the current study aimed to compare the conventional and functional H:Q ratios calculated by PT and TW. Ninety-three male professional soccer players from Brazilian first division teams performed isokinetic concentric and eccentric contractions of the quadriceps and the hamstrings at 60°/s. Muscle strength balance was calculated using the conventional torque ratio (CTR) and conventional work ratio (CWR), functional torque ratio (FTR) and functional work ratio (FWR) were highly and moderately correlated between them (r?=?0.83 and r?=?0.73, respectively). The Wilcoxon statistical test revealed significant differences between CTR and CWR, as well as FTR and FWR (p?T-test demonstrated significant differences in mean CTR–CWR and FTR–FWR, whereas Bland–Altman plots showed non-consistent bias. In addition, the chi-square test demonstrated significant differences between players below the conventional reference values and functional reference values (p?相似文献   

A mixed methods comparison of teachers' lunar modeling lesson implementation and student learning outcomes

The authors compare three teachers' adaptations and implementation of a lunar modeling lesson to explain marked differences in student learning outcomes on a spatial-scientific lunar assessment. They used a modified version of the Practices of Science Observation Protocol (P-SOP; Forbes, Biggers, &; Zangori, 2013 Forbes C., Biggers, M., &; Zangori, L. (2013). Investigating essential characteristics of scientific practices in elementary science learning environments: The practices of science observation protocol (P-SOP). School Science and Mathematics, 113, 180–190.[Crossref] , [Google Scholar]) to identify ways in which features of inquiry were emphasized in each classroom. Additionally, classroom communities of practice were categorized as task-based or practice-based (Riel &; Polin, 2004 Riel, M. &; Polin, L. (2004). Learning communities: Common ground and critical differences in designing technical support. In S. Barab, R. Kling, &; J. Gray (Eds.), Designing for virtual communities in the service of learning (pp. 16–52). Cambridge, MA: Cambridge University Press.[Crossref] , [Google Scholar]). The authors found that student learning outcomes were related to the fidelity with which the teachers implemented the lesson. Teachers with higher P-SOP scores fostered more of a practice-based learning community than task-based one, which also paralleled greater student learning gains. Although the students' scores did not differ by teacher on the preassessment, they did differ significantly on the postassessment, indicating that the curricular choices and learning communities developed by the teachers impacted what students were able to learn.     

Statistical Techniques for the Study of Institutional Differences

David P. Ausubel, in his theory of meaningful, verbal reception learning, espouses the presentation of appropriate subsumers (organizers) to students prior to the presentation of the learning task. The question to be answered in the present study was: Are there significant differences in learning when students are presented organizers before the learning passages (pre-organizers), after the learning passages (post-organizers), or when they are presented only the learning passages (no-organizers). An analysis of covariance, using reading vocabulary achievement as the covariate, was used to compare adjusted treatment group means. No significant differences were found among adjusted means (p<. 15) in the available pool of third- and sixth-grade classes. Organizers do not facilitate learning when presented to similar classes using similar social studies materials.

An Investigation of How Well People in Denmark, Norway and Sweden Understand Each Other's Written and Spoken Languages. Scand. J. educ. Res. 20, 49‐72. Soldiers in the three countries were exposed to spoken and written texts in the two other Scandinavian languages and their comprehension was tested by asking them questions about the contents and by asking them to translate certain central words in the texts into their own language. Questions about certain important non‐linguistic factors such as education level, domicile, travels to the other Scandinavian countries, reading in the other Scandinavian languages, exposure to radio and television programs from the other Scandinavian countries, own estimation of other Scandinavian language comprehension and attitudes towards these languages were also included. The answers to these questions were used to throw light on the results of the language test.     

Becoming Qualitative Researchers: A Collaborative Approach to Faculty Development

Five junior scholars, representing two departments and four program areas in the College of Education at the University of North Texas, committed themselves to a long-term, systematic, research-based learning program in order to further their knowledge and skills as qualitative researchers. In this essay, this community of learners describes their collaborative efforts to develop more effective skills in one method of qualitative research, in-depth, oral history interviewing. Through their cross-discipline, research-based, faculty development model, the authors offer helpful direction to other higher education faculty who seek to improve their ability to conduct and also to guide students in qualitative investigations.
