Yes / In March, the Department of Health (DH) released the Learning from Mistakes League, in which NHS organisations are ranked by levels of openness and transparency (DH, 2016). While a welcome first step toward the centralised and open promotion of learning since the publication of the Francis and Berwick reports three years earlier, unfortunately, the league can be considered misleading for a number of reasons.

In our diploma thesis we deal with mistakes in written discourse of Russian speakers. We are trying to explore the mistakes of Russian speakers on the materials of the Czech language and create several lingvodidactic recommendations about how to interpret the topic and how to prevent mistakes. We indtroduce a plentifully used communicative method for teaching foreign languagues and discribe four basic language skills. Key words: communicative method, basic language skills, written discourse, written communication, mistake, classification of mistakes, causes of mistakes, evaluation of mistakes.

The purpose of this study was to investigate the prospective teachers&rsquo / knowledge of mistakes held by elementary students in fractions and their proposed strategies to overcome those mistakes. The data were collected from 149 prospective elementary mathematics teachers enrolled in the elementary mathematics education programs from a public university in Central Anatolian Region. Fraction Knowledge Questionnaire was used to accomplish the purpose of the study. The data collection tool included nine open ended questions, and each question had two sub-tasks. In this study, the items in the &ldquo / Fraction Knowledge Questionnaire&rdquo / were analyzed in-depth in order to reach a detailed description of prospective teachers&rsquo / knowledge about students&rsquo / mistakes on fractions. The results of this study revealed that prospective elementary mathematics teachers mostly could identify the students&rsquo / mistakes. However, although prospective teachers could notice the students&rsquo / mistakes, they could give superficial reasons for these mistakes. Furthermore, verbal explanations, using area representation, using real life model, reviewing prior knowledge, teaching standard algorithm, asking guided questions, using simple examples, using counter examples, using drill and practice, making students aware of their mistakes, and increasing students&rsquo / motivation were the suggested strategies by prospective teachers in order to overcome students&rsquo / mistakes in fractions.

This work explores the techniques of printing and preparation, in combination with technical mistakes. It aims to show how to use technical mistakes in different printing and preparation techniques as a design method to find accidental aesthetic expressions using the stripe as a tool to enhance and clarify the methods modification. The method confronts today’s textile industry by showing how these mistakes could develop into new expressions within textile design when fast -fashion is no longer an obligation. The stripe is a common shape, and is explored to clarify the method ans show how different techniques can change the stripes in various ways. This resulted in to three pieces each representing a technique; one transfer printed, one digital printed and one with the starting point in screen print. They present examples of how more time for developing mistakes in textile design can lead to development of the common shape of a stripe, broaden the technical limitations, and give a value to mistakes in the textile industry. By taking the method further more mistakes could be developed, and how to produce the developed designs in the industry could be investigated.

TITLE: Developing activity and creativity in teaching fractions in grades 6 to 7 AUTHOR: Bc. Lenka Svobodová DEPARTMENT: Department of Mathematics and Mathematical Education SUPERVISOR: Mgr. Marie Tichá, CSc. ABSTRACT: The thesis consists of a theoretical and an empirical part. The theoretical part looks at the cognitive process of pupils and possible ways of their motivation during fractions teaching. Furthermore, it outlines causes of lack of understanding of fractions and re-education interventions. The empirical part is based on a qualitative research whose main objective was to determine how the pupils are able to solve fractions exercises independently and creatively and what mistakes they make. Various methods of data collection were used, such as interview with teachers on issues of fractions teaching in elementary schools, non- standardised test with fractions exercises and additional interview with the tested pupils. This part also describes the preparation of the research, the research itself and its results KEYWORDS: fractions, interpretations, representations, models, misunderstandings, mistakes, teaching approaches

The thesis focuses on mistakes and problems in manipulations with the algebraic expressions occurring to pupils at the second level of Elementary school. The thesis is divided into a theoretical and experimental part. The theoretical part contains description of manipulations with algebraic expressions, selected results of international comparative surveys, and an analysis of related foreign research. Analysis of three series of textbooks, according to which pupils involved in the experimental project are taught, is essential for understanding of possible origins of their mistakes. The classification of mistakes in manipulations with algebraic expressions is included. At the core of the work is the experimental part aiming to identify problems and mistakes of pupils when manipulating and working with algebraic expressions. The participants of the research consisted of six third-grade pupils of an eight-year Grammar school (13-14 years old) and eight ninth-grade pupils of an Elementary school (14-15 years old). Test used for my experiment came from the GA ČR project Critical parts of mathematics in primary school. The investigation was carried out individually with each pupil by the method of monitoring clinical interviews over the solution of the test tasks. The obtained data was qualitatively...

(anglicky) Fractions are one of the critical areas of mathematics at the primary school. The aim of this diploma thesis is to describe didactic practices used when teaching fractions (focusing in particular on additive operations with fractions) and find out what strategies are used by pupils at selected tasks focusing on fractions, what difficulties are an obstacle in their successful solutions and what images of fractions the pupils have. The theoretical part contains considerations about the teaching and learning of mathematics, the overview of the historical development of the concept of fraction and operations with fractions and also selected research related to fractions. The practical part begins with the analysis of the textbooks where their semantic and structural models used for fractions are identified as well as ways of teaching operations with fractions. My own research consists of semi-structured interviews with five experienced teachers (one of whom is not qualified) on the topic of teaching fractions, the difficulties of pupils with fractions and of clinical interviews with three pupils from different primary schools. Interviews with the pupils were focused on the solution of the diagnostic tasks in the field of fractions. Transcripts of both interviews were analyzed by techniques...

Title: Pupils' problems when solving problems requiring substitution Abstract: The work focuses on 8th and 9th graders' difficulties and mistakes when solving problems using substitution. The theoretical part defines the used concepts and discusses selected results from international comparative studies and studies focusing on substitution. The main goal of the work is to identify pupils' difficulties and mistakes they make when solving problems using substitution and to discover their origin or cause. To achieve this goal the empirical part begins with an analysis of three sets of textbooks used by pupils involved in this research study. This is followed by a description of conducting and subsequent analysis of fifteen clinical interviews on problems with substitution with 14 to 15 year old pupils (9th graders from elementary schools and 3rd graders from lower secondary grammar schools). In the final part the most common mistakes are summarised and relations to their possible origin in the set of textbooks used looked for. The conclusion is that pupils do not have problems with substitution as such when substituting natural numbers into first power variables. However, this does not hold for substitution of variable in the second power. Pupils have problems when substituting for a variable with a negative...
