Microcomputer-Based Laboratory in Secondary School Chemistry Education
Stratilová Urválková, Eva ; Šmejkal, Petr (advisor) ; Bílek, Martin (referee) ; Nesměrák, Karel (referee)
Eva Stratilová Urválková; Dissertation Thesis Title: Microcomputer-Based Laboratory in Secondary School Chemistry Education Abstract School experimental practice should reflect the real laboratory practice so that school science keeps in touch with reality. Todays laboratories are fully equipped with instrumental devices that are often presented in media, so it is necessary that students have experience also with this way of experiments. For school purposes seem suitable probeware (school experimental systems), that combine modern technology with concept of student-centered learning (eg inquiry based science education) that should successfully prepare students for lifelong learning. During recent years probeware has become one of discussed topics in Czech science education, but there has been a lack of research examining whether both teachers and pupils are prepared to accept and implement probeware into school chemistry curriculum. Almost none research has been done in field search describing the way of using the probeware and microcomputer-based laboratory in Czech school curriculum. Presented mixed method research focuses on attitudes of chemistry teachers (N = 65), pre-service chemistry teachers (N = 38) and students (N = 50) regarding attitudes to general devices and measuring devices (or probeware) to...

Activities with Probeware for chemistry oriented vocational schools
Jenčuš, Henrich ; Šmejkal, Petr (advisor) ; Stratilová Urválková, Eva (referee)
Many of the experiments available for working with probeware are aimed at the grammar school level. However, with the proliferation of more sophisticated sensors, there is an opportunity to develop experiments for chemistry-oriented vocational schools (specialization Applied Chemistry). These experiments would benefit from the advantages of the vocational school - more time available in the laboratory, better instrumentation, and a wider range of learning topics allowing for more challenging experiments. However, these would also work as advanced experiments for grammar school level chemistry education. The theoretical part discusses probeware, its use for teaching chemistry, the range of different available sensors and their advantages and disadvantages, as well as sources of available experiments, their categorization and comparison with the Framework Education Programme education topics. This thesis introduces a set of 5 different, fully developed and laboratory-validated experiments selected in accordance with the requirements of the Framework Education Programme and School Education Programme for chemistry-oriented vocational schools. In addition to the write-up of the process of their design and validation in this thesis, the annex provides developed materials for direct use in school labs,...

Alternative devices for data collection and possibilities of employment in chemistry education
Staníček, Jan ; Šmejkal, Petr (advisor) ; Stratilová Urválková, Eva (referee)
Probeware already has a long history and it is now more recognised as an effective utility in chemistry education. One of the main obstacles for probeware to expand is the lack of the financial means which is one of the main reasons why they are still plenty of teachers that do not use probeware in chemistry education. To solve this issue it is important then to find a cheaper replacement for original probeware so every teacher can use it. The rise of e-shops and cheap international shipping led to the appearance of cheap alternatives to relatively expensive probeware and to professional devices for instrumental methods. It is then vital to find these alternatives and to test their potencial of becoming a fine replacement of the original probeware and that is also the main topic of this bachelor thesis. The results have shown that these cheaper devices already exist and by buying them a lot of financial means can be saved. This alternative probeware provides quality reproducible outputs based on real expectation which are not that much different from the outputs of the original probeware. They are also some disadvantages like long delivery time of goods from foreign e-shops and its complaint. As well as, advanced functions for data analysis are not available in the case of devices with autonomous...

Database of experiments with probeware fo secondary school
Jenčuš, Henrich ; Šmejkal, Petr (advisor) ; Stratilová Urválková, Eva (referee)
A new database of chemical experiments was proposed in this work. This database would be oriented on experiments done with probeware either as a demonstration in a class or as a microcomputer based laboratory. To gather information about the aspects of the experiments that are significant for the teachers choice of inclusion of the experiment into their class, a survey amongst the teacher has been done in two steps - a series of interviews and a questionnaire. A review of current experiment databases in czech language and the materials contained within was also conducted. As a part of this work, twelve sample experiments have been created to be added to the new database.
