A non-speech response mode similar to the one used by Prepack (1971) to teach language to a chimpanzee was utilized to teach two simple language functions to three autistic children. The response mode consisted of picking up a geometric symbol and placing it on a response tray. The geometric symbol was the basic unit in this language system. The symbols were used to represent objects in the environment and relationships between the objects.

The problem with which this study is concerned is that of comparing the results of teaching community college students enrolled in a transferable mathematics sequence for business and economics majors by a computer-aided instructional program and by the traditional lecture method. In order to effectively resolve this problem, an A Programming Language System 360 (APL/360)-aided instructional program was developed and an experimental study was conducted. The APL/360-aided instructional program consisted of three sets of materials.: a manuscript on APL/360, a list of APL programs defining operators relevant to a computer-aided study of calculus, and a collection of problems based on these programs and calculus concepts. The subjects for the experiment were forty-four students enrolled in three sections of Mathematics 112 at Mountain View College of the Dallas County Community College District. The control group, students taught by the traditional lecture method, consisted of twenty-one students. The experimental group, students taught by the APL/360-aided instructional program, consisted of twenty-three students. The same instructor taught all students. The essential difference in the two teaching methods was the use of the computer as a teaching-learning aid in the computer-aided instructional program. The computer was a course supplement to classroom instruction and aided students in obtaining insight into the nature of mathematical concepts as well as serving as a computational aid.

The youngest word class type used to arouse great interest and discussions when entering the grammar; in some countries (e. g. in Germany) particles have been an object of systematic research. However, many other languages still lack a complex description of particles as a class on its own - they represent an appropriate material also for comparative researches. Differences in functioning and theoretical treatment of particles have been present in typologically different languages but they can emerge also in related languages, even in the case of Slovak and Czech. Lexicographical and grammar descriptions of these languages provide only small sets of particles (in Slovak roughly amounting to 400, in Czech exceeding 200) and are usually divided by authors into small groups and further on into even smaller subgroups. Due to specific features as well as to paradigmatic and syntagmatic relations with other language or speech phenomena even one particle or a couple of them or a narrowly defined group of particles can become an object of individual scientific and research projects. Step by step, our thesis presents the development of attitudes towards particles as an independent word class in general and in Russian linguistics in particular, grammar descriptions of particles in Slovak, Czech and other...

Diploma thesis "Principles of popularization of scientific knowledge on the Czech and American news servers" evaluates and compares news published during three month period in scientific sections of news servers in the Czech Republic and the United States of America. The thesis follows room provided for scientific topics, the audiovisual features and theme agenda on NYTimes.com, USAToday.com, iDnes.cz and Novinky.cz. The results are accomplished through the quantitative content analysis which is supplemented by the qualitative semiotic analysis. The semiotic analysis determins compositional and narrative structures and the language features in the articles. It is very important to be concerned about the scientific journalism, as science is important in people's lives and, furthermore, it is the public who helps to support scientific efforts financially. Thus, scientists should be concerned about and aware of science communication in media.
