Plants and soils from natural ecosystems harbor great diversity of soil microorganisms, which could potentially contribute to the sustainability of horticulture. The knowledge about using wild plant species and soil from natural ecosystem to improve the crop health will advance the application of ecological…

We examine how soil inoculation influences aboveground organisms (i) directly, and indirectly via (ii) its effects on plant chemistry or volatile emission, or via (iii) mediating the effects of belowground pathogens on aboveground organisms via the shared plant.

Feedback from fellow students on academic writing is as informative as that of teachers.

The soil ecosystem consists of the largest reservoir of biodiversity on Earth.

We examine how soil-derived legacy effects of plants structure natural ecosystems, determine aboveground plant insect interactions, and how we can use soil legacy effects to restore degraded ecosystems.

Research has shown that the impact of feedback can be very powerful on second language acquisition. However, how to provide adaptive feedback on speaking skills in foreign languages and how to provide differentiated support in secondary schools in regular secondary schools classes of often 25-30 students?…

To what extent can contingent, formative feedback in lectures, facilitated by web-based ICT, increase students’ self-efficacy and (academic, behavioral, and cognitive) engagement? And how are self-efficacy and engagement influencing students’ performance and course evaluations?

By growing in a soil plants change the biotic and abiotic properties of the soil in which they grow.

Feedback from fellow students on academic writing is as informative as that of teachers. That is one of the findings in Bart Huisman's (ICLON) dissertation. Defence on 12 September.

As soon as young children are introduced to rules and start to learn to obey to those rules, it can be difficult for parents to remain sensitive when their children try to bend or break those rules. The short-term (preventive) VIPP-SD intervention aims at enhancing parental sensitivity in interaction…

The mission of the Plant Science research programme is to contribute to the sustainable production of high quality crops, flowers and high-value bio-based products. This is realised by generating fundamental knowledge of basic biological processes related to development of plants and their interaction…

Children and adolescents really do use their ‘smart’ brain areas. This has been confirmed by an extensive and long-running study of the brain carried out by developmental psychologist Sabine Peters . Her findings can have important consequences for education. PhD defence 27 January.

Restoring a natural plant environment on exhausted agricultural lands and in nature areas is difficult. We can speed this up by steering the soils towards the desired situation. This is what Martijn Bezemer, newly appointed Professor of Ecology of Plant-Microbe-Insect interactions at Leiden University’s…

Parents appear to be extremely sensitive to feedback they receive about their child. Just how sensitive depends on the (‘rose-tinted’) glasses through which they look at their child. All this can be seen in the brain. Neuroscientist Lisanne van Houtum and her Leiden colleagues published on this issue…

Seven master’s students had lunch in the characteristic Humanities Faculty Room with Faculty Board members Mirjam de Baar (vice dean) and Aurelie van ’t Slot (student board member) and gave feedback about their experiences at Leiden University.

Can positive peer feedback break the cycle of negative self-relevant cognitive processes and reduce self-reported anxiety in early adolescents?

What are the global relationships between environmental conditions and abundance of distinct types of mycorrhizal fungi in soil and plant roots?

How can we organise society so as to keep our planet habitable for us and for all other life forms around us? To answer this question, Leiden researchers collaborate across disciplines, from biology to data science, and from environmental economy to archaeology.

The origin and evolution of galaxies are closely tied to the cyclic feedback processes between stars and the interstellar medium (ISM).

How can video on professional practices in university courses be used in a valid and useful way for assessment and feedback?

Helping first-year students at the Faculty of Governance and Global Affairs find their way in a rapidly changing university world because of Covid-19. That was the goal of the mentor project that has been running since this academic year. At the end of January, the first phase ends and in February new…

The aim of this research is to gain insight into the approaches of learning to teach. Teacher learning processes, feedback in novice-expert interaction and the impact of the interaction are explored.

Participation in the matching module is a compulsory part of the admission and application procedure for all applying students of this programme.

Systems pharmacology aims to apply techniques from systems biology to pharmacological models.

Fundamental insights into the working of the adolescent brain help lecturers and parents to teach adolescents to function better. Professor Eveline Crone studies executive functions – such as planning and behaviour – in the adolescent brain.
