Students’ perceptions of assessment: a comparative analysis between Portugal and Sweden

This paper aims at investigating students’ perceptions about assessment, especially the ways in which it is put into practice. Data were collected through questionnaires in different programmes in Portugal and Sweden. In total, 173 students from Portugal and 72 from Sweden participated in the study. Findings showed that students had similar ideas about assessment, such as verification of knowledge and learning, tests and grades. Their experiences of assessment methods used varied in the two countries, which can partly be explained by differences in national education systems. A learner-oriented perspective is prominent in the use of assessment methods, but at the same time student influence on assessment is perceived as low in both countries. Implications of the findings are analysed, namely issues regarding a learner-oriented perspective and the effectiveness, influence, trust, times and methods of assessment.     

Isolated Obesity Is Not Enough to Impair Cardiac Autonomic Modulation in Metabolically Healthy Men

Purpose: To evaluate whether excess body mass influences the heart rate variability (HRV) indexes at rest, and to correlate adiposity indicators and the aerobic fitness with cardiac autonomic variables in metabolically healthy young adults. Method: In all, 41 untrained males (M_age = 21.80, SD = 2.14 years), 14 normal weight (M_BMI = 22.28, SD = 1.86 kg?m^?2), 11 overweight (M_BMI = 26.95, SD = 1.43 kg?m^?2), and 16 obese (M_BMI = 33.58, SD = 3.06 kg?m^?2) metabolically healthy (normal values of blood pressure, fasting blood glucose, triglycerides, and total cholesterol), underwent evaluations of the HRV at rest and of the peak oxygen consumption (VO₂ peak) during maximal exercise on a cycle ergometer. Results: Blood pressure, heart rate, HRV indexes, casual blood glucose, oxidative stress, and antioxidant activity did not differ among the groups. The VO₂ peak (mL?kg^?1?min^?1) was lower in the obese group compared with the normal weight and overweight groups. The body mass (r = ?.40 to ?.45) and abdominal circumference (r = ?.39 to ?.52) were slightly to moderately correlated with SD1, SD2, RMSSD, SDNN, pNN50, LF, and HF indexes and total power. The VO₂ peak (mL?kg^?1?min^?1) was slightly to moderately correlated (r = .48 to .51) with SD2, SDNN, and LF indexes in the individuals with excess body mass. Conclusion: Cardiac autonomic modulation at rest was preserved in metabolically healthy obese young men. However, the indicators of adiposity, as well as the aerobic fitness were correlated with cardiac autonomic modulation in the individuals with excess body mass.     

Book and Material Reviews

The time has come for us to shift the dominant paradigm for schoolbased consultation from a behavioral to an ecobehavioral perspective. Although a thorough examination of this issue is precluded by the space limitations of this article, there is sufficient room to initiate the discussion and suggest that we begin a process of transition by adopting this new mind-set to describe and guide our consultation behaviors. Rather than precipitating a radical break with current practice, an ecobehavioral world view should help direct us toward evolutionary changes that move the field forward without having to sacrifice the wisdom gleaned thus far from our collective past.     

Preschoolers' Relational Aggression with Siblings and with Friends

As part of a longitudinal study examining sibling and friend relationships in early and middle childhood, relational aggression by 4-year-olds and their interaction partners in semi-structured free play sessions with siblings and friends was examined during sibling sessions involving both same-gender and mixed-gender sibling pairs. Identifiable acts of relational aggression occurred during many of the interactions observed, but there was also a wide range in the amount of relational aggression produced. Both boys and girls used relational aggression with their siblings much more than they did with their friends. Although boys' and girls' relationally aggressive behaviors occurred at similar rates, the form and function of their relational aggression varied depending on the age and gender of their sibling.     

The educational nature of different ways teachers communicate with children about natural phenomena

This empirical study analyses the qualitatively different ways in which teachers approach children's learning in and about nature. The empirical data consists of video observations of children and teachers communicating with one another around natural phenomena found during excursions into a forest. Variation theory is presented as a framework for analysing the opportunities teachers provide for children's learning. The study identifies three qualitatively different ways in which teachers communicate with children: one based on the principle of opening up dimensions of variation, the second building on presumed shared previous experience as a resource for making sense of a novel observation and the third involving children through using a make-believe playful approach. The implications of these three different approaches for children's learning are discussed.
