An assessment approach that tailors to children’s instructional needs

In this thesis, dynamic testing principles were applied to examine young children's potential for learning. Our studies focused on the role of cognitive flexibility, to further increase our understanding of the cognitive processes involved in children's ability to learn from instruction and feedback,…

Within Leiden University, we sometimes conduct research with laboratory animals. We only do this when when we cannot answer the research question in any other way.

Can metabolomic profiling be used to predict resistance against insect herbivores in plants?

The examination service delivers efficient and accurate processing of written tests and digital exams in platforms such as ANS and Remindo. Additionally, we offer guidance in interpreting statistical analyses of exam outcomes.

If gifted children are experts in using strategies, why do they experience problems with learning? Why do they underachieve?

Children with a specific phobia are excessively afraid of certain objects, animals or situations. Specific phobias are common in children, but they can make the child’s life at home, school and outside quite difficult. Together with a large international team, we developed the KibA-program to help children…

Can dynamic testing provide us with insight in children’s potential for learning?

What is the relationship between outcomes of dynamic testing and cognitive flexibility in young children?

Read all the study choice tips and take the tests to get to know more about yourself. These tests can give you insight into your interests, competences, values and personality. That can help you make your study choice.

Jaroslaw Kantorowicz, assistant professor at the Institute of Security and Global Affairs, isolated the reaction of the public to the potential breach of constitutional fiscal rules from the reaction of other players, such as the opposition, media and civil society organizations.

Subproject of the NWO Smart Culture Grant research project 'The Critical Visitor'.

What are the 'dark' components of the universe?

Statistical considerations guide the design and implementation of the experiments that scientists perform. For instance, in a clinical trial about a the efficacy of a treatment, its effect in a certain minimum amount of patients has to be observed in order to make confident assertions about the efficacy…

Can process-oriented dynamic testing be applied to everyday educational practice?

What is the effect of a dynamic training in children’s inductive reasoning skills and how is it related to children’s school performances and language development.

This thesis investigates durational aspects of the Italian mobile diphthongs with respect to other rising diphthongs and monophthongs and it shows to what extent the monophthong/diphthong alternation still occurs in contemporary Italian.

Uncovering task solving processes in dynamic testing

The quality of vaccines is still often tested by using laboratory animals. That has to change, according to researchers from Leiden University and the vaccinological institute Intravacc. Together they went searching for a test method that makes animal testing unnecessary. The first promising results…

Testing chemical substances without using animals. It seems a utopia, but a European team is going to develop a way to make this a reality. The RISK-HUNT3R project, led by Leiden professor Bob van de Water, received 23 million euros from the European Commission for this purpose. The project was launched…

Thanks in part to the persistence of a Leiden research group, cancer could be detected in the near future with just a single drop of blood. Not only can the diagnosis be determined at an earlier stage, but the blood test is also cheap, fast and patient friendly. The first results of this method seem…

Songbirds apparently use mnemonics rather than more complex grammatical rules to recognise structures in which they have been trained. Leiden behavioural biologist Caroline van Heijningen published an article on this subject on Tuesday 17 November in PNAS.

Nonadiabatic energy transfer from the translational motion (T) of a molecule impinging on metal surface to the metal’s electrons may determine whether the molecule can lose enough energy to adsorb or react.

Bioprinters that enable scientists to engineer complex tissues and organs. It sounds like science-fiction, but not for the scientists of the Alireza Mashaghi lab at the Leiden Academic Centre for Drug Research. The lab has recently been equipped with two state-of-the-art bioprinters: BioX and LumenX+.…

The Bolivian people will make their opinion known on a change to the constitution in a referendum on 21 February. Leiden University organised a symposium on the referendum on 11 February. The aim of the change is to allow President Evo Morales to remain in power until 2025.

Pushing the limits and trying things out. The academic year of the Honours Academy started on 10 October and all the speakers encouraged students to jump in at the deep end.

Researchers from the Leiden University Medical Center (LUMC) are working on the first diagnostic test for leprosy that can be used outside a laboratory. This will not only reliably diagnose leprosy, but also be cheap and easy to use. Leprosy mainly occurs in low-income countries. A double challenge…

Researchers at Leiden University Medical Center (LUMC) and Radboud university medical center have been given the green light to deliberately infect volunteers with malaria in order to test a highly promising vaccine on them.

Toxys, Leiden University and Leiden University Medical Center have agreed immediately to commercialise and also develop further the ToxProfiler technology invented at the two institutions. ToxProfiler allows for rapid toxicity hazard identification of novel and existing drugs, chemicals, and other substances.…

To check whether the classroom scanners are secure, a ‘pen test’ was performed in the Lipsius building on Monday 28 March. This involved switching on the person counters for a day so that ethical hackers could try to gain access to the system.

When an employee returns from an area considered to be a corona risk, can their employer require them to have a corona test? This is a complicated issue if you consider labour law and legislation in relation to privacy of employees. However in some cases Barend Barentsen, Professor of Labour Law, believes…

On 11 May the House of Representatives voted in favour of a law that will enable some sectors to reopen sooner than planned with the aid of test certificates. Political philosopher Josette Daemen is critical of the new legislation. ‘Just because we get used to measures doesn’t make them desirable.’

Leiden University Medical Center (LUMC) and the Centre for Human Drug Research (CHDR) are taking part in the phase 2 clinical trial of Janssen Vaccines’ candidate coronavirus vaccine. The vaccine will be tested on 45 test participants in Leiden from 14 September onwards.

Interest group Animal Rights has started a test case to prompt the Netherlands Food and Consumer Product Safety Authority (NVWA) to tackle farmers who do not adequately protect their livestock against wolves. The test case concerns a rejected enforcement request to the NVWA. In it, the NVWA were called…

It is the spring of Arts and Science! On Tuesday April 16, Young Academy Leiden organized an interfaculty lunch during the Spring of Arts and Science, a season of interdisciplinarity that is being organized together with Jong Universiteit Leiden (JUL). This first event was a visit to Rijksmuseum Boe…

A full overview of all loans and debts between banks would help preventing a new financial collapse. But banks do not provide this information. An econophysics model by Diego Garlaschelli and collaborators reconstructs the most probable situation and finishes first place in two independent tests.

How can we reduce CO2 emissions from industry? Leiden psychologists Emma Mors and Christine Boomsma are examining the public perception and acceptance around the capture and storage of carbon dioxide. This is part of the ALIGN CCUS European research programme.

Researchers from the Plant Ecology and Phytochemistry group at the Institute of Biology Leiden (IBL) received an STW (Stichting Technologische Wetenschappen) grant for applied studies in plant herbivore resistance with potential for a novel resistance test.

Children could do better at school if they exercise during their maths, English and science lessons, a study has suggested. Researchers reviewed 42 studies that looked at the benefits of physical activity in the classroom for youngsters.

In this paper, Kantorowicz argues that reverse party favoritism exists. He exploits the fact that during the SARS-CoV-2 pandemic crisis, the Polish government was keen to launch postal voting in the presidential elections scheduled for May 2020.
