Development of a computer-based adaptive training programme for the part-whole concept

Based on the development of a computer-based training programme for pupils at the end of primary school or at the beginning of lower secondary school, which is dedicated to the part-part-whole concept as a part of the basic arithmetic competencies of primary school mathematics, is empirically evaluated and can be implemented in regular mathematics lessons, this programme prototype is to be revised. The aim is to implement further requirements for the support programme. The support programme is to be used during individual (approx. 30-minute) work phases. The pupils receive support during regular math-lessons. In addition, the internet-based implementation on tablets can also create a spatial separation and thus avoid possible stigmatisation.

Evaluation of special schools with the special educational needs on mental development in the state of Brandenburg

The aim of the project is to evaluate schools with a special educational need on "mental development". Data-based findings are to be obtained as a basis for deriving possibilities for optimising the education of pupils with the special educational needs "mental development" in the state of Brandenburg at special schools as well as in joint teaching (GU). There are three central sub-objectives for this:

(1) To capture the organisation of the special schools with the special educational need "mental development" as well as the schools with pupils with the special educational need "mental development" in the common lessons with regard to the organisation of lessons and all-day lessons, the staff planning as well as the heterogeneity of the pupils.
(2) Furthermore, the composition of the student body at schools with the special educational need "mental development" as well as at schools with students with the special educational need "mental development" in the common education is to be captured.
(3) ultimately, to identify challenges and derive possibilities for optimising the organisation of special schools with the special educational need "mental development" as well as schools with pupils with the special educational need "mental development" in joint teaching.

  •  Target group: Headmasters and pedagogical staff at special schools with the special educational focus "mental development" at schools with pupils with the special educational needs "mental development" in joint teaching.

Professional development in inclusive schools under conditions of the Covid-19 pandemic

Based on theoretical concepts and research findings on leadership styles of school headmasters and professional competence facets of teachers, the present study aims to investigate to what extent profession-related experiences, attitudes and stresses of school headmasters and pedagogical staff have changed against the background of the Covid-19 pandemic. It is assumed that an increased cooperation orientation of school headmasters in particular leads to increased cooperative activities on the part of the teaching staff and thus causes fewer negative changes in the profession-related experiences of the teaching staff (e.g. stress) and learning-relevant characteristics of pupils (e.g. motivation).

Questionnaires will collect information on professional activities as well as the teaching and learning processes in distance learning settings from a retrospective and current perspective. Through the detailed assessment of cooperative activities and their effects on different groups of actors within the school, the study demonstrates under which conditions inclusive teaching and learning in distance learning settings can succeed. The knowledge gained will be applied in the area of teacher training and in-service training.

Scientific Evaluation "Common Learning and School Centres in the Federal State of Brandenburg

In the school years 2018/2019 and 2019/20, the evaluation of common learning schools and school centres in the federal state of Brandenburg will examine how common teaching in primary and secondary education affects the competence development of pupils and how this is related to teachers' professional characteristics, teaching characteristics and contextual characteristics. For this purpose, three different, interacting levels are taken into account: (1) the level of the pupils (analysis of individual developmental trajectories), (2) the class level (analysis of the contextual conditions of teaching, including the professional characteristics of the teachers) and (3) the school level (analysis of characteristics of the teaching staff and school organisational characteristics). The final report on the project is publicly available on the website of the Brandenburg Ministry of Education, Youth and Sport.

Lost in Math (LoMa) - Development of a diagnostic test to assess basic arithmetic competencies at the end of primary school (grade 4)

This test can be used to assess pupils from the end of grade 4 with regard to basic arithmetic competencies in primary school, which, according to scientific findings, are an absolute prerequisite for the acquisition of the mathematics of secondary school (from grade 5). It is a critical test with a representative sample (age group: 4th to 7th grade) which, after evaluation, creates a performance profile and reveals relevant support needs which, if they exist, should be addressed promptly. The test will consist of a screening and an in-depth test. Both the screening and the in-depth test are necessary to determine the achievement profile.

ELA - Development of Easy Tasks

The research project "ELA - Development of Easy Tasks" is dedicated to the construction and empirical testing of easy, diagnostically meaningful test tasks in the subjects German and mathematics for primary school children with special educational needs. Our aim is to better take into account the special needs of these children in the development of appropriate tasks and to adapt the graphic and linguistic design of the tasks accordingly. At the same time, we aim at the equivalent measurement of central constructs (e.g. reading competence) in large school performance studies in order to be able to make reliable statements about the quality of our educational system for these pupils as well.

Development of a working memory test and an examination procedure for mathematical competencies to test the influence of working memory according to Baddeley on mathematical skills of preschool children - Dissertation

Within the framework of a study of preschool children aged 4 to 6 years, a working memory test based on the model of Baddeley and Hitch (1974) was designed and an existing arithmetic test was further developed. The aim of the individual studies is to examine the influence of working memory, differentiated according to the individual components: phonological loop, visuo-spatial notepad and central executive, on the pre-school acquisition of mathematical competences.
