AbstractDesigning problems and learning activities is a key factor to initiating students’ engagement with the course material and influencing their reasoning processes. Although tasks and problems are a central part of teaching and assessments in the chemistry classroom, they may not engage students in deep reasoning or in a way that is intended through a task. Some problems may cause an algorithmic or a surface approach. Even with designing clever problems, students may not use a larger variety of chemistry ideas and connect them in meaningful ways. Here the idea of scaffolding students’ answering process comes into play. Structuring students’ reasoning process through instructional prompts or structured worksheets supports students in activating and connecting knowledge pieces in a more meaningful way and positively slows down their fast decision-making process. This paper will discuss the importance of asking questions in chemistry teaching and highlights the idea of contrasting cases, drawn from cognitive psychology, as a task design principle. In addition to having contrasting cases as a good problem format, the idea of scaffolding students’ reasoning while solving contrasting cases through the use of instructional prompts that scaffold the reasoning process will be exemplarily showcased for mechanistic reasoning in organic chemistry.

AbstractRecent scholarship on Pentecostalism in Africa has debated issues of transnationalism, globalisation and localisation. Building on Bayart's notion of extraversion, this scholarship has highlighted Pentecostals' far-flung networks as resources in the growth and consolidation of particular movements and leaders. This article examines strategies of extraversion among independent Pentecostal churches. The aim is less to assess the historical validity of claims to independency than to account for its appeal as a popular idiom. The findings from fieldwork in a Malawian township show that half of the Pentecostal churches there regard themselves as 'independent'. Although claims to independency arise from betrayals of the Pentecostal promise of radical equality in the Holy Spirit, independency does sustain Pentecostals' desire for membership in a global community of believers. Pentecostal independency thus provides a perspective on African engagements with the apparent marginalisation of the sub-continent in the contemporary world. Two contrasting cases of Pentecostal independency reveal similar aspirations and point out the need to appreciate the religious forms of extraversion. Crucial to Pentecostal extraversions are believers' attempts to subject themselves to a spiritually justified hierarchy.

SummaryAs a contemporary development in welfare policy, contractualism stipulates discretionary rights and obligations for each client, some of whom are quite vulnerable. The contractual design promotes empowerment, but entails sanctions for non-compliance. This article investigates how rationales of empowerment and discipline shape social work practice and uses a Foucauldian governmentality perspective to investigate interrelations between political objectives and individual practices. Two contrasting cases are used to explicate how rationales of empowerment and discipline simultaneously operate in social work within the contractual design.FindingsWith its emphasis on clients’ responsibility and empowerment, contractualism is a subtle yet efficient mode of governance, but disciplinary actions both rely on and undermine objectives of empowerment.ApplicationsSocial workers and clients must manoeuvre complexities as they exert empowering and disciplinary practices. These rationales of governance should be explicit and subject to professional and ethical considerations in the same way as other forms of professional authority directed at reliant, vulnerable clients.

Mountainous areas require appropriate measurement strategies to cover the full spectrum of details concerning the energy exchange at the Earth’s surface and to capture the spatiotemporal distribution of atmospheric dynamic and thermodynamic fields over them. This includes the range from turbulence to mesoscale processes and its interaction. The surface energy balance needs appropriate measurement strategies as well. In this paper, we present an overview of important experiments performed over mountainous terrain and summarize the available techniques for flow and energy measurements in complex terrain. The description includes ground-based and airborne in situ observations as well as ground-based and airborne remote sensing (passive and active) observations. Emphasis is placed on systems which retrieve spatiotemporal information on mesoscale and smaller scales, fitting mountainous terrain research needs. Finally, we conclude with a short list summarizing challenges and gaps one faces when dealing with measurements over complex terrain.
