Vulnerabilities of web applications
Žák, Vojtěch ; Mareš, Martin (advisor) ; Parízek, Pavel (referee)
Se stále dostupnějším připojením k internetu roste i počet webových aplikací a jejich uživatelů. S tímto nárůstem - jak už to bývá se vším - se zvětšuje i počet lidí, kteří se snaží nedostatky v těchto aplikacích zneužít. V této práci si ukážeme, jak nejčastější zranitelnosti webových aplikací fungují, a jak se jich jako vývojáři můžeme vyvarovat. Zaměříme se i na to, jak odhalit zranitelnosti aplikací jako uživatelé, a jak provést útoky zneužívající tyto zranitelnosti. Součástí této bakalářské práce je také projekt Vulnerability Presentation Server (Vul- pes), který vznikal ve spolupráci se společností CZ.NIC. Jedná se o soubor webových aplikací, ve kterých jsou za účelem jejich demonstrace záměrně ponechány zranitelnosti zmíněné v tomto textu. 1
Starting points for a new physics curriculum
Kolář, Petr ; Žák, Vojtěch (advisor)
This thesis presents starting and supporting points for a new secondary school physics curricu- lum and the methodology which was used. The research design was inspired mainly by the objectivist grounded theory. 29 in-depth semistructured interviews were conducted with elite Czech physicists and there were identified 79 ideas about a secondary school physics curricu- lum. After approximately two years, 56 ideas were used in the questionnaire survey where re- spondents expressed on a Likert scale their degree of agreement with the ideas. Respondents were natural scientists (non-physicists), experts on didactics of physics, secondary school phys- ics teachers and 26 of 29 physicists who were also participants of the interviews. In the ques- tionnaire survey, there were identified ideas on which all groups of respondents agreed and which are stable in time in the group of physicists.

Assessment of Physics Tuition Quality Parametrs
Žák, Vojtěch ; Kolářová, Růžena (advisor) ; Svoboda, Emanuel (referee) ; Janík, Tomáš (referee)
This thesis deals with acquisition and evaluation of parameters of the physics tuition quality at high schools. Mapping the existing approaches to the education quality and tuition quality, the work includes also description of the progress and results of an expert investigation, contributing to creation of a new technique for monitoring the physics tuition and assessing its quality. Following chapters describe details of the research assessing the quality of the physics tuition performed by ten teachers at seven Prague high schools, discussing the validity and reliability of the technique created. Within the thesis, didactic preparation has been elaborated based on results of the research, usable for teaching the physical topic titled "Energy and Conservation Laws in Mechanics". I have taught this topic and the tuition has been assessed using the new technique. The thesis includes also a manual for future users of the monitoring and assessment technique.
Laboratory works in physics for upper secondary schools
Koutská, Barbora ; Žák, Vojtěch (advisor) ; Kekule, Martina (referee)
This Bachelor thesis is dealing with laboratory classes at secondary schools. Thesis offers ideas for five laboratory classes which were carried out during regular teaching at the secondary school. Besides other things there are work sheets here to be used with given classes and for the teachers there are metodical instructions which have arisen from implementation in classes and from subsequent reflection. Laboratory classes are thematically focused on the field of vibration and interference which run through different fields of physics. The aim of these classes is mainly to develop students' creativity in solving problems, their practical skills during preparation of experiments, also to develop critical attitude to the information and the discussion about mistakes and negligencies which emerged during measuring and working on the computer. As it turned out in research dedicated to motivation in learning physics, laboratory classes prepared in this way - i.e. experiments carried out by students themselves and using computers in processing data - are loved by students and because of that they have a great motivational capacity.

Attitudes of czech students toward science subjects and teaching methods used in this subjects (Data analysis of TIMSS research)
Harapesová, Tereza ; Mandíková, Dana (advisor) ; Žák, Vojtěch (referee)
In the presented work I study czech students attitudes toward science subjects, especially physics, and science teachers attitudes toward their job and teaching methods in science subjects and also their trends consequent upon data analysis of TIMSS 2007. Results were compared with data from previous surveys in years 1995 and 1999 and data from PISA research. My thesis is built on my previous bachelor thesis from 2008 that studied student attitudes toward science subjects upon data analysis of TIMSS 1995 and 1999 and PISA.
Field Trip Activities to IQpark
Zajacová, Blanka ; Kekule, Martina (advisor) ; Žák, Vojtěch (referee)
Title: Field Trip Activities to iQpark Author: Blanka Zajacová Department: Department of Physics Education Supervisor: RNDr. Martina Kekule, PhD., Department of Physics Education Abstract: This thesis deals with preparation of physically oriented worksheets and methodical sheets for pupils and teachers of secondary and high schools who visit the iQpark science centre. The theoretical part describes some teaching methods and forms and their classification. Further it sums up the results of research of materials for pupils and teachers that are published on the web sites of ten science centres in Europe and USA. Six physical field trip activities to iQpark for high school students and four for secondary school students were prepared as a part of the thesis. One worksheet for pupils and one methodical sheet for accompanying teachers were prepared for each field trip. A pilot study of the worksheets was carried out in cooperation with instructors of iQpark. 284 pupils from 20 different secondary schools and 407 students from 22 different high schools participated in the pilot study. Individual tasks were finalized on the basis of an analysis of pupils' responses that was carried out after the first testing. A pilot study of the methodical sheets was also carried out. 18 pedagogical workers expressed their...
Solved problems in mechanics
Soukup, Marek ; Mandíková, Dana (advisor) ; Žák, Vojtěch (referee)
: In terms of the thesis an electronic collection of solved problems was created. The solved problems embrace the mechanics of solid object theme. There are total 17 of solved problems in the collection. The problems cover the level from secondary school to introductory university lectures on classical mechanics. The problems are selected from existing collection and publications. Every problem contains an assigment, a structured help. a detailed solution and a result. In the first part of the thesis a problem and an aim of the thesis are specified. Next, the overview of the subject matter which is teached in primary schools, secondary schools and at university follows. The common schoolbooks are also described. The last part of the thesis describes the characteristics, the technical solution, the structure and the content of the electronic collection of solved problems. In the conclusion the results of work and the future perspective are summerized. An attachment includes 5 solved problems. All solved problems and the text of the thesis are included in the electronic form on the enclosed CD.
