Science Journals in the Preschool Classroom

We believe that science journals can be used in the preschool classroom as tools for supporting and assessing children’s learning of science- and literacy-relevant content and procedures. To support this argument, we review changes in attitudes about the cognitive competencies of preschoolers and in teaching and learning expectations for early childhood education. We describe practical aspects of using science notebooks with this age group and discuss specific ways that journals support children’s learning. Finally, the role of journals in assessment is discussed.     

Sex differences in self‐estimation of multiple intelligences among Portuguese adolescents

This study investigated the relationship among sex, attitude toward intelligence, and self‐estimation of multiple intelligences for self and parents among Portuguese adolescents in secondary schools. Two hundred and forty‐two adolescents estimated their own and their parents' IQ scores on each of Gardner's 10 multiple intelligences: verbal (linguistic), logical (mathematical), spatial, musical, body‐kinesthetic, interpersonal, intrapersonal, existential, spiritual, and naturalistic. They also answered six simple questions concerning intelligence and intelligence tests. There were various sex differences in self‐estimated IQ: males rated themselves higher on overall, mathematical, spatial, intrapersonal, spiritual, and naturalistic IQ compared with females. Multiple regressions indicated that verbal, logical, and intrapersonal intelligence were significant predictors for self and parents overall IQ estimations. Factor analysis of the 10, the 8, and the 7 self‐estimates scores did not confirm Gardner's classification of multiple intelligences. Males were more likely to believe in sex differences in intelligence than females. Results are discussed in terms of the growing literature in the self‐estimates of intelligence, as well as limitations of that approach.     

TransFormers in knowledge production: building science–practice collaborations

This article places action learning in the context of system innovation, as it studies the potential use of action learning for system change. In order to effect such system change, collaboration between actors from different institutional backgrounds is essential. To gain insight into if and how action learning can be applied for system change, we study three system change projects in Dutch agriculture. We focus specifically on the approaches developed by the project leaders for collaboration between the scientists and the entrepreneurs and analyse how the interaction between these two contributed to the learning process within the project. This article concludes with guiding concepts for action learning for system change in the field of sustainable development of agriculture and beyond.     

From teaching from the heart to teaching with a heart: Segmenting filipino college students’ views of their teachers’ caring behavior and their orientations as cared-for individuals

Caring, as a universal human phenomenon, should permeate elementary, secondary and tertiary level instruction. The practice of teaching, especially at the tertiary level, is not only substantial and procedural but relational as well. To teach with a heart is the essence that makes teaching a form of caring. When teaching is viewed as a form of caring, teachers become relational geniuses in their own right. This study is an attempt to segment Filipino college students’ views (n=1000) of their teachers’ caring behavior and their orientations as cared-for individuals. The identified clusters of teacher roles that indicate caring behavior imply that acts of teaching become acts of caring depending on how the teachers, theefficient cause of education, perform their ordinary tasks in the context ofextraordinariness. Such extraordinariness spells out a big difference in the way teachers practice the so-calledsingle loop caring or caring visibility anddouble- loop caring or caring presence. The former refers to teaching from the heart while the latter pertains to teaching with a heart. Interestingly, the extent to which teachers’ caring behavior is felt and experienced by the students positively shapes their orientations as cared-for individuals.     

Cinematic Rendering in Anatomy: A Crossover Study Comparing a Novel 3D Reconstruction Technique to Conventional Computed Tomography

Integration of medical imaging into preclinical anatomy courses is already underway in many medical schools. However, interpretation of two-dimensional grayscale images is difficult and conventional volume rendering techniques provide only images of limited quality. In this regard, a more photorealistic visualization provided by Cinematic Rendering (CR) may be more suitable for anatomical education. A randomized, two-period crossover study was conducted from July to December 2018, at the University Hospital of Erlangen, Germany to compare CR and conventional computed tomography (CT) imaging for speed and comprehension of anatomy. Sixteen students were randomized into two assessment sequences. During each assessment period, participants had to answer 15 anatomy-related questions that were divided into three categories: parenchymal, musculoskeletal, and vascular anatomy. After a washout period of 14 days, assessments were crossed over to the respective second reconstruction technique. The mean interperiod differences for the time to answer differed significantly between the CR–CT sequence (−204.21 ± 156.0 seconds) and the CT–CR sequence (243.33 ± 113.83 seconds; P < 0.001). Overall time reduction by CR was 65.56%. Cinematic Rendering visualization of musculoskeletal and vascular anatomy was higher rated compared to CT visualization (P < 0.001 and P = 0.003), whereas CT visualization of parenchymal anatomy received a higher scoring than CR visualization (P < 0.001). No carryover effects were observed. A questionnaire revealed that students consider CR to be beneficial for medical education. These results suggest that CR has a potential to enhance knowledge acquisition and transfer from medical imaging data in medical education.

Impressions of disadvantage: II-Monitoring and assisting the student at risk

Two studies on monitoring and assisting students at risk are presented against a contemporary perspective in higher education: that of monitoring and developing the quality of student learning. A basis for risk categorisation at an individual level is outlined, and the effects of an intervention aimed at students at risk are evaluated in two contrasting settings. At risk in the present study represents, in conceptual terms, a relatively extreme set of learning behaviours.The first study approximates an ideal set of circumstances in which an individual-level intervention for students conceptually at risk is described. The second study reflects the uncompromising reality of a large first-year service course, in which a reduced form of the same intervention was pragmatically attempted. In both interventions the emphasis was on assisting students to engage manifestations of their own self-reported, contextualised study behaviour. This was the starting point of a developmental and reflective programme in which students were not taught study skills, but were rather assisted to develop deeper contextual perceptions, metalearning awareness, and internal locus.The targeted students in these studies, and the basic nature of the intervention employed, differ considerably from those used in other intervention studies. The first study produced positive results, while the second study did not. An overall conclusion is that, while interventions of the type described can assist students to develop their learning potential, they can only do so in carefully managed circumstances that are sensitive to individual students' learning problems and the discipline-specific context in which these occur.     

The Sensitivity of Value-Added Teacher Effect Estimates to Different Mathematics Achievement Measures

Using longitudinal data from a cohort of middle school students from a large school district, we estimate separate "value-added" teacher effects for two subscales of a mathematics assessment under a variety of statistical models varying in form and degree of control for student background characteristics. We find that the variation in estimated effects resulting from the different mathematics achievement measures is large relative to variation resulting from choices about model specification, and that the variation within teachers across achievement measures is larger than the variation across teachers. These results suggest that conclusions about individual teachers' performance based on value-added models can be sensitive to the ways in which student achievement is measured.
