We contribute to possibilities of quantifying shifts in pupils' and students' attitudes toward the field of science, specifically biology, and present the Czech translation of the Colorado Learning Attitudes about Science Survey modified for biology (CLASS-Bio). In addition to quantifying the attitudes, the survey also includes the expression of th...

Digitising and aggregating local floristic data is a critical step in the study of biodiversity. The integrative web-based platform Pladias, designed to cover a wide range of data on vascular plants, was recently developed in the Czech Republic. The combination of occurrence data with species characteristics opens many opportunities for data analys...

We examined how upper secondary school students perceive the usefulness and difficulty of biology disciplines. Czech students (N = 192) from three schools answered a questionnaire with 5-point Likert scales. We tested the influence of gender and experience with the individual biological disciplines at upper secondary school on the perception of the...

Národní časopisy jsou důležitým prostředkem pro pěstování dialogu o směřování jednotlivých oborů. Členové redakčních rad těchto časopisů mohou ovlivnit kodifikaci měřítek prací publikovaných v daném oboru, bývají proto označováni jako gatekeepers, tedy „strážci brány vybírající, který obsah a forma vědeckého sdělení jsou přijatelné“. Abychom si vyt...

The Pladias (Plant Diversity Analysis and Synthesis) Database of the Czech Flora and Vegetation was developed by the Pladias project team in 2014-2018 and has been continuously updated since then. The flora section of the database contains critically revised information on the Czech vascular flora, including 13.6 million plant occurrence records, w...

As motivation is one of the crucial keys to better education, we explored the motivation of New Zealand students toward studying Science. We used the Science Motivation Questionnaire [1] to measure the motivation score of 648 students from 14 different high schools. To be able to identify and confirm latent components of the Science Motivation Ques...

We investigated attitudes Czech high school students' toward genetically modified organisms (GMOs) and their knowledge about GMOs. The objectives were to investigate students' attitudes toward, and knowledge of GMO and find possible relations. 185 Czech students from 6 high schools completed the survey. The attitudes of students toward GMOs were po...

Background: Genetic testing rapidly penetrates into all medical specialties and medical students must acquire skills in this area. However, many of them consider it difficult. Furthermore, many find these topics less appealing and not connected to their future specialization in different fields of clinical medicine. Student-centred strategies such...

It is generally acknowledged that land-use structure and its changes influence levels of invasion by alien plants across the landscape. In this study, we asked how land-use changes over the last 180 years influenced spatial patterns of alien plant invasions in the Czech Republic. We hypothesize that (i) dynamically changing landscapes with a high l...

Recently available extensive datasets on plant distributions across the whole national floras and on functional traits of such floras, and increasing availability of fine-scale information on the abiotic environment make it possible to explore the trends in plant traits across geographical space and explain them as a function of large-scale environ...
Article
This paper is dedicated to horse chesnut as a suitable model organism for teaching botany at all levels of our schools. Horse chestnut is literally predisposed to didacticisation in botany teaching due to its general distribution, large and conspicuous organs; we are basically sure that pupils really know it. The paper focuses mainly on the morphol...

Research on the Czech flora has a long tradition and yielded a large number of records on the occurrence of plants. Several independent electronic databases were established during the last three decades in order to collect and manage these records. However, this fragmentation and the different characteristics of each database strongly limit the ut...

Opakovaně se objevují apely, že škola má žáky vést mimo jiné ke kritickému myšlení, práci s literárními zdroji, badatelsky orientované výuce a plánování experimentů. Těmi, kdo má tyto přístupy a metody zprostředkovávat, jsou učitelé. Je proto důležité, aby budoucí učitelé rozeznávali důvěryhodné zdroje literatury, kriticky vyhodnocovali informace a...

The science field trips in educational practice publication intends to examine various aspects of the topic of field trips at schools and to interconnect all these approaches. The book is a result of collaboration of respected experts in various fields of science as well as educational theorists attempting to find common language in order to produc...
Conference Paper
We test various features for recognition of leaves of wooden species. We compare Fourier descriptors, Zernike moments, Legendre moments and Chebyshev moments. All the features are computed from the leaf boundary only. Experimental evaluation on real data indicates that Fourier descriptors slightly outperform the other tested features.
Article
A system for recognition of woody species in Central Europe according to the images of their leaves is described. Our own data set, which includes 151 species at this moment, with at least 50 leaves per species was used. After segmentation, the contour of the leaf was traced. Fourier descriptors normalised to translation, rotation, scaling and star...
