The influence of multiperspectivity in history texts on students’ representations of a historical event

School history textbook narratives of a nation’s past often present limited perspectives, which may impede the aim of teaching history from multiple perspectives. Less is known about the influence of including multiple perspectives on students’ representations of the past. This study examines the extent to which students include multiple perspectives when processing a schoolbook text that includes multiple perspectives compared to a schoolbook history text containing fewer perspectives. Tenth grade students (N = 104) in four schools were randomly assigned to read one of two texts on the Dutch Revolt and asked to make a summary. Multiperspectivity was analysed through the representation of actors, aspects of scale, dimensions and historiography. The students working with the text having high multiperspectivity showed more perspectives in their representations. In the summaries, these students included significantly more perspectives than did the students using the text with fewer perspectives. Moreover, these students’ representations of the main actors were more nuanced. The students using the text with high multiperspectivity situated the conflict in a broader international context and integrated more historiographical dimensions. The insights generated by these outcomes emphasize the important role of textbooks when aiming to teach history from multiple perspectives.

     

Parents’ perceptions of secondary school students’ motivation and well-being before and during the COVID-19 lockdown: the moderating role of student characteristics

During the COVID-19 lockdown of spring 2020, Dutch children were being homeschooled. We examined how parents’ (n = 470) perceptions of secondary school students’ (M_age = 14.23 years) need satisfaction, academic motivation and well-being differed before the lockdown (assessed retrospectively) and during the lockdown. Furthermore, we examined the differential impact of the lockdown for different groups of children based on parental educational level, academic track, gender and special educational needs (SEN). Results indicated that students’ motivation and well-being as perceived by parents decreased during the lockdown and this could be explained by decreases in need satisfaction. Most student characteristics did not moderate the effects of the lockdown, except for SEN. The lockdown effects were less negative for children with SEN, especially gifted children and children with behavioural disabilities, than for children without SEN. Results are discussed with regard to their practical implications after the lockdown and for future lockdowns.     

Individual characteristics of students in vocational education moderating the relationship between school engagement and vocational identity

In any country, there is a group of students who are at risk of dropping out of school without any qualifications. This is detrimental for many of those students, because failure to graduate increases risks of unemployment and societal exclusion. To reduce this risk, specialized curricula aim to prepare these students for their working life by fostering the development of a vocational identity, that is, how they define themselves as workers. As a prerequisite to achieving this goal, students need to attend school and feel engaged with school. The curricula seek ways to stimulate emotional school engagement, taking into account the heterogeneous target group of students they serve. To address potential consequences of individual differences, this questionnaire study (N=996) conducted in the Netherlands explored how various individual characteristics of students in these specialized curricula moderated the relationship between emotional school engagement and vocational identity. Results show that stronger school engagement always coincided with a stronger vocational identity; however, the strength of the relationship varied. Stimulating emotional school engagement was specifically important for the subgroups of students who are young, less agreeable, less motivated, and less resilient. In order to foster the vocational identity of their students, the specialized curricula are recommended to draw nuanced conclusions and formulate refined strategies to effectively respond to the heterogeneous group of students who are at risk of dropping out.

     

Ethical requirements for reconfigurable sensor technology: a challenge for value sensitive design

Information technology is widely used to fulfill societal goals such as safety and security. These application areas put ever changing demands on the functionality of the technology. Designing technological appliances to be reconfigurable, thereby keeping them open to functionalities yet to be determined, will possibly allow the technology to fulfill these changing demands in an efficient way. In this paper we present a first exploration of potential societal and moral issues of reconfigurable sensors developed for application in the safety and security domain, in the context of a large scale R&D-project in the Netherlands. We discuss the subtle distinction between the relevant notions of reconfigurability, function creep, and unrestricted or unforeseen technological affordances. We argue that the feature of reconfigurability makes context of use the central issue in the assessment of the societal and moral impact of the technology. It follows that the design of good policies for new application contexts has to be central in a value sensitive design approach to reconfigurable technology.     

Stability of pedalling mechanics during a prolonged cycling exercise performed at different cadences

The aim of this study was to analyse the effect of pedalling rate on the pattern of mechanical torque application and on neuromuscular fatigue during prolonged cycling exercise. Eleven well-trained individuals performed three 1-h pedalling sessions, at 50 rev?·?min^?1, 110 rev?·?min^?1 and a freely chosen cadence, at an intensity corresponding to 65% of their maximal aerobic power. The mechanical torque applied on the right pedal was recorded for 30?s every 5?min while pedalling. Contractile and neural properties of the quadriceps and hamstring muscles were analysed before and immediately after each of the three pedalling sessions. The post-exercise reduction in knee extensors maximal voluntary contraction was significant (P <?0.01) irrespective of the cadence, but no difference was found between cadences. The use of a particular cadence did not lead to preferentially central or peripheral fatigue. An increase in cadence resulted in greater positive and negative work generated during pedalling. The mechanical pattern was not altered during the exercise, whatever the selected cadence. The present study demonstrates that despite the occurrence of neuromuscular fatigue, trained individuals maintained a stable pedalling pattern throughout an endurance cycling exercise for cadences ranging from 50 to 110 rev?·?min^?1.     

A modified TRIMP to quantify the in-season training load of team sport players

Abstract

The aims of the study were to modify the training impulse (TRIMP) method of quantifying training load for use with intermittent team sports, and to examine the relationship between this modified TRIMP (TRIMP_MOD) and changes in the physiological profile of team sport players during a competitive season. Eight male field hockey players, participating in the English Premier Division, took part in the study (mean±s: age 26±4 years, body mass 80.8±5.2 kg, stature 1.82±0.04 m). Participants performed three treadmill exercise tests at the start of the competitive season and mid-season: a submaximal test to establish the treadmill speed at a blood lactate concentration of 4 mmol · l^?1; a maximal incremental test to determine maximal oxygen uptake ([Vdot]O_2max) and peak running speed; and an all-out constant-load test to determine time to exhaustion. Heart rate was recorded during all training sessions and match-play, from which TRIMP_MOD was calculated. Mean weekly TRIMP_MOD was correlated with the change in [Vdot]O_2max and treadmill speed at a blood lactate concentration of 4 mmol · l^?1 from the start of to mid-season (P<0.05). The results suggest that TRIMP_MOD is a means of quantifying training load in team sports and can be used to prescribe training for the maintenance or improvement of aerobic fitness during the competitive season.
