Stepping into other people’s shoes proves to be a difficult task for high school students: assessing historical empathy through simulation exercise

In 2011, the Finnish National Board of Education assessed the learning outcomes of history with a study whose results raised doubts about the fulfilment of the goals of history education. This article seeks to expand awareness about Finnish adolescents’ understanding of historical empathy. The study assessed twenty-two 16–17-year-old high school students’ ability to understand predecessors’ actions in particular historical situations. The study also examined how well a simulation exercise works as a tool of empathy teaching and evaluation. Students participated in the simulation and afterwards the students were interviewed. They also participated in a survey that measured their attitudes before and after the exercise, and wrote an essay at the end of the course. The results of the study show that most of the high school students did not reach the goals set for history teaching. The weak performance of students is explained by the strong tradition of history teaching which has been continuing in Finnish schools despite the curriculum reform. Teaching still concentrates on passing a meta-narrative on to students who have not yet enough experience of explaining historical events from a multiperspective point of view.     

Self Organising Wayfinding Support for Lifelong Learners

Lifelong learning puts learner self-direction centre-stage. However, increased responsibility should not come at the price of over-burdening or abandonment of learners as they progress along their learning journey. This paper introduces an approach to wayfinding support for lifelong learners based on self-organisation theory. It describes an architecture which supports the recording, processing and presentation of collective learner behaviour designed to create a feedback loop informing learners of successful paths towards the attainment of learning goals. The approach is presented as an alternative to methods of achieving adaptation in hypermedia-based learning environments which involve learner modelling. The article concludes with a discussion of the questions being addressed in our ongoing research.     

Developmental Pathways to Preference and Popularity in Middle Childhood

This study examined the associations between children's early life experiences with parents, ego resiliency and ego undercontrol, and peer group social status in a longitudinal, multimethod study from infancy to middle childhood. Participants were 129 children (52% boys) who were followed from 15 months of age to 9 years and their primary caregivers from the Nijmegen Longitudinal Study on Infant and Child Development. The measurements included observations of parent–child interaction, teacher ratings of ego resiliency and ego undercontrol, and peer‐reported social status. Quality of parental interactive behavior was associated with ego resiliency and ego undercontrol. Ego resiliency and ego undercontrol were uniquely related to preference and popularity. The findings provide insight into the developmental pathways leading to the two distinct types of social status.     

Interactive lectures in engineering education

This article discusses an alternative approach to lecturing: the interactive lecture. In the literature, interactive teaching is forwarded as a means to increase the effectiveness of lectures. Members of lecturing staff still seem, however, reluctant to incorporate interactive teaching in their classes,as interaction reduces the time they can devote to explaining subject matter. Lecturers often voice the concern that they will not get enough material across in interactive lectures and that this consequently will negatively affect student learning. In order to establish whether or not the concerns of lecturers could be empirically verified, an experimental study was conducted. This study examined the effects of interactive teaching in lectures, using an interactive voting system and peer instruction, on: the attainment of learning objectives; student motivation; and student perception of the instruction offered. From the results a complex picture emerges. Results suggest that students may learn as much in interactive lectures compared with traditional lectures, but a traditional lecture may also result in active student involvement. The study indicated that interactive teaching will not automatically result in students who are more activated, and provided additional insight into conditions for successful interactive teaching. Finally, interactive teaching was shown to influence positively student motivation.     

The completeness property of the set of real numbers in the transition from calculus to analysis

This paper focuses on teaching and learning the set of real numbers R and its completeness property at the university level. It studies, in particular, the opportunities for understanding this property that students are offered in four undergraduate correlative courses in Calculus and Analysis. The theoretical framework used in the study draws on concepts developed in the Anthropological Theory of Didactics, especially the notions of praxeology and mathematical organization. The paper shows different expectations concerning the same notion (R and its completeness) through different school levels, and intends to bring up some reflections about the transition from Calculus to Analysis.

Rapid microfluidic solid-phase extraction system for hyper-methylated DNA enrichment and epigenetic analysis

Genetic sequence and hyper-methylation profile information from the promoter regions of tumor suppressor genes are important for cancer disease investigation. Since hyper-methylated DNA (hm-DNA) is typically present in ultra-low concentrations in biological samples, such as stool, urine, and saliva, sample enrichment and amplification is typically required before detection. We present a rapid microfluidic solid phase extraction (μSPE) system for the capture and elution of low concentrations of hm-DNA (≤1 ng ml⁻¹), based on a protein-DNA capture surface, into small volumes using a passive microfluidic lab-on-a-chip platform. All assay steps have been qualitatively characterized using a real-time surface plasmon resonance (SPR) biosensor, and quantitatively characterized using fluorescence spectroscopy. The hm-DNA capture/elution process requires less than 5 min with an efficiency of 71% using a 25 μl elution volume and 92% efficiency using a 100 μl elution volume.     

INTRODUCTORY ADDRESS

The participants in the workshop are welcomed and the rationale for the workshop and its objectives are stated. As the diversification of higher education structures is necessary and is taking place spontaneously throughout eastern and central Europe, the need has arisen to give it some direction, above all to ensure that higher education evolves in ways compatible with the transition to democracy and a market economy.

The Kinetic-Molecular and Thermodynamic Approaches to Osmotic Pressure: A Study of Dispute in Physical Chemistry and the Implications for Chemistry Education

Osmotic pressure proves to be a useful topic for illustrating the disputes brought to bear on the chemistry profession when mathematics was introduced into its discipline. Some chemists of the late 19th century thought that the introduction of mathematics would destroy that chemical feeling or experience so necessary to the practice of chemistry. These chemists were critical of the suggestion that mathematically analogous expressions for macroscopic phenomena implied similar kinetic-molecular processes at the microscopic level because they believed that a chemical phenomenon discovered by chemical experience through experiment was a more reliable guide to molecular processes than was mathematics. In general physical chemists of the modern era are also critical of the suggestion that mathematically analogous expressions for macroscopic phenomena imply similar kinetic-molecular processes at the microscopic level but for different reasons. The mathematical analogy between the van’t Hoff law and the ideal gas law is regarded as an artefact of the mathematical thermodynamic treatment of osmosis and not as a result of a correlation of kinetic-molecular processes. Some chemists however, albeit a minority, while agreeing with the thermodynamic treatment of osmotic pressure suggest that the mathematical analogy is more significant than being simply a mathematical artefact. They propose a controversial kinetic-molecular model of osmotic pressure which they believe has more educational value than the thermodynamic model. The significance of mathematically analogous expressions for different chemical properties and the desirability of highlighting unifying chemical principles for the teaching and learning of tertiary level chemistry are discussed predominantly in the context of historical osmotic studies.     

The Dissertation Process and Mentor Relationships for African American and Latina/o Students in an Online Program

To examine the problem of underrepresentation of minority students in doctoral programs, the author utilized a mixed-methods case study of an online doctoral program in which large numbers of African American and Latina/o students were enrolled. Themes uncovered in the study centered on specific academic and nonacademic challenges, the important role of mentors, and the impact of degree completion on students. Recommendations include effective mentor–mentee matching and increased sensitivity to particular challenges for underrepresented minority students in doctoral programs.
