We investigated pictorial versus contextual support effects over and above teaching of definitions on children's word learning and retention as well as the moderating role of reading comprehension. In a between-subject pre-post-retention test control group design, Dutch fourth graders learned concrete and abstract Dutch words. The context group…

This longitudinal randomized trial study investigated the effects of phonological specificity training on second language (L2) vocabulary learning. Eighty-six Dutch secondary-school students participated in one of two experimental conditions or in an animacy judgment (active control) condition. Participants in the phonological specificity training…

The teaching of historical time is an important aspect in elementary school curricula. This study focuses on the effects of a curriculum intervention with "Timewise," a teaching approach developed to improve students' understanding of historical time using timelines as a basis with which students can develop their understanding of…

Research has demonstrated that teachers working in early childhood education and care (ECEC) are proficient in offering emotional support to young children, but markedly weaker when it comes to instructional support. We conducted a controlled experimental study in the Netherlands, to investigate the effects of targeted in-service training on…

Professional development of teachers has become an essential condition in today's knowledge-based society to sustain the quality of teaching. Therefore, the Dutch government promotes this professional development. As a result, Professional Development Plans (PDPs) are now increasingly used to stimulate and support the professional development of…

Data-based decision making (DBDM) is an important element of educational policy in many countries, as it is assumed that student achievement will improve if teachers worked in a data-based way. However, studies that evaluate rigorously the effects of DBDM on student achievement are scarce. In this study, the effects of an intensive…

This study investigated the long-term effects of a professional development intervention for beginning urban teachers and explored which characteristics and activities in school organisations contributed to the sustainability of these effects. A quasi-experimental study (n = 72) investigated whether the positive effects of the programme were…

This study used an experimental, pretest-posttest control group design to investigate whether participation in a large-scale inquiry project would improve primary teachers' attitudes towards teaching science and towards conducting inquiry. The inquiry project positively affected several elements of teachers' attitudes. Teachers felt less anxious…

We examined the effects of adaptive word retrieval intervention on a classroom vocabulary program on children's vocabulary acquisition in kindergarten. In the experimental condition, word retrieval was provided in a classroom vocabulary program, combining implicit and explicit vocabulary instructions. Children performed extra word retrieval…

We investigated effects of listening to single or multiple storybook readings versus testing with and without feedback on children's breadth (i.e., the number of words) and depth (i.e., the quality of word knowledge) of vocabulary learning. Kindergartners (n = 125) were divided into 3 intervention and 1 control conditions. Children in the control…

This study investigated to what extent self-efficacy, learning behavior, and performance outcomes relate to each other and how they can be positively influenced by students asking for and seeking feedback within a problem-based learning (PBL) environment in order to meet today's requirements of marketing graduates. An experimental…

A dialogic storybook-based intervention integrating dialogic storybook reading with early literacy activities is studied with a longitudinal quasi-experimental study design. The effects of this intervention, in addition to a regular early childhood education (ECE) program, on kindergartners' vocabulary and phonological awareness development are…

In this paper, we investigated whether student reading comprehension could be improved with help of a teacher Professional Development (PD) program targeting goals, data use, and instruction. The effect of this PD program on 2nd- and 3rd-grade student achievement was examined using a pretest-posttest control group design. Applying propensity score…

This study tested effects of a program that offers teachers universal classroom management strategies, on teachers' burnout symptoms and self-efficacy, and their teaching behaviors. Data were collected from 147 teachers (mean age = 38.4 years, SD = 10.8) in 15 special secondary education schools for students with emotional and behavioral problems,…

This study aimed to evaluate a training programme for Dutch teachers in six institutes for nursing education to support students' reflection skills. The research question was: what are the feasibility, quality and effects of the programme? The training programme focused on four competences of teachers regarding instructing, guiding, giving…
