The use of still images in instruction has a long history in the field of education. With the widespread use of microcomputers and the development of graphic software, the ability to create and use animated images has greatly increased; today many people use animated images in their teaching and training activities. Since the use of different types of images in instruction has various influences on students'learning results, the different effects between animated images and still images have been studied widely among researchers. However, the research results are not consistent. Some research results show that animated images are more effective than still images and some show no difference or less effective results. This experimental study explores the effects of animated images and still images on college students' learning of motion-related tasks and non-motion related tasks, with the students possessing different levels of field dependence-independence. This study found that: For learning tasks involving motion and/or change, animated images were more effective than still images for college students, and field dependent students benefited more from animated images than did the field independent students. However, for learning tasks that did not involve motion or change, there was no difference in learning results from the use of still images as opposed to animated images. In addition, for such learning tasks, there was no difference in the learning benefits of still images to field dependent versus field independent learners. / Ph. D.

<p> Increasing evidence indicates that giving individuals control over their practice schedule facilitates motor learning (Titzer, Shea, & Romack, 1993; Wu & Magill, 2004, 2005). A recent study within cognitive psychology (Son, 2004) found that individuals massed practice on tasks they judged as hard but spaced practice on tasks they judged as easy. The purpose of this experiment was to examine how self-regulated practice impacts motor learning and the strategies used by individuals as a function of task complexity. Participants were required to move a mouse-driven cursor through a pattern of coloured squares, pausing only long enough in each square to make an appropriate button press (white square=left button, black square=right button). Task complexity (4 easy and 4 hard patterns) was determined by the combined effects of the arrangement of the grid of squares and the hand used to manipulate the mouse (easy =dominant hand, hard=non-dominant hand). Participants were randomly assigned to one of eight groups: blocked, random, self-regulated, and yoked to self-regulated, performing either the easy or hard tasks. The number of switches between patterns were recorded as well as temporal and accuracy measures. The self-regulated groups were ineffective in acquisition, but showed the most stable and improved performance in retention, irrespective of task difficulty. Moreover, although switch strategies of the self-regulated groups differed between and within task complexity, the motor learning advantage was generalized. Taken together, these results reveal that an individual's strategic approach to practice may change as a function of task complexity, with no detriment to motor learning and adds to the growing body of literature that suggests self-regulated practice is an important variable for effective motor learning.</p> / Thesis / Master of Science (MSc)

The main goal of this dissertation was to create and verify own multicomponent tasks of interdisciplinary character based on analysis of types of tasks occured in international research. Newly created multicomponent learning tasks were classified by task type, solution form, cognitive demands and task variety. Tasks of the same form were ordered to pairs, their difficultness, vulnerability and rate of success were verified. Multicomponent learning tasks were assigned verbally or nonverbally (charts, tables or pictures). Closed jobs (ordering items, matching items, multiple choice questions, true/false questions) and open jobs (wide-answer items, short-answer items) were used in complex of tasks. Rate of success of individual tasks was processed by non-parmetric statistical Wilcoxon test based on form, gender and type of study. Research survey was complemented by pupils' self- reflection questionnaires and teachers'questionnaires about testing process. Key words Multicomponent learning task, taxonomy of learning task, scientific literacy, reading literacy, self-reflective questionnaire.

The aim of the research reported in this licentiate thesis was to create an environment that could support students’ learning about logarithms. To develop such a learning environment, Davydov’s ‘learning activity’ was used as a theoretical framework for the design. A new tool was created, that was used by the students to unfold and single out some of the unique properties of logarithms when solving different learning tasks. The construction of the model was inspired by Napiers original idea from 1614, i.e. exactly 400 years ago, by using two number lines; one arithmetic (i.e. based on addition) and one geometric (i.e. based on multiplication). The research approach used was learning study where teachers and researcher worked collaboratively in an iterative process to refine the research lesson. The study was conducted in six groups with six teachers in upper secondary school in a major city in Sweden. The sample comprised about 150 students and data were collected by filming lessons and by interviews with some of the students. The data were analysed using an analytic framework derived from ‘learning activity’ and the results show what supports, but also what does not support, the creation of an environment for supporting students’ learning of logarithms. The results from the study are related to former research regarding instrumental/procedural vis-à-vis relational/conceptual understanding and also about research about students’ ‘errors and misconceptions’. It is argued that the formal definition of logarithms, y = 10x &lt;-&gt; x = lgy (y &gt; 0), should not be used to introduce the concept, instead a new way is proposed. One conclusion is that it is possible to reconstruct logarithms without using the definition as a tool. The results from the analysed lessons show how students looked for ways to solve learning tasks using the new tool. The definition and the identities regarding logarithms appear as bi-products of the students learning activity. When analysing students actions, they rarely over-generalised mathematical rules, e.g. used the distributive law, or separated log-expressions, e.g. adding log expressions part by part, that seemed to be an issue according to former research.

Real-world learning tasks present a range of issues for learning systems. Learning tasks can be complex and the training data noisy. When operating as part of a larger system, there may be limitations on available memory and computational resources. Learners may also be required to provide results from a stream. This thesis investigates the problem of incremental, relational learning from imperfect data with constrained time and memory resources. The learning process involves incremental update of a theory when an example is presented that contradicts the theory. Contradictions occur if there is an incorrect theory or noisy data. The learner cannot discriminate between the two possibilities, so both are considered and the better possibility used. Additionally, all changes to the theory must have support from multiple examples. These two principles allow learning from imperfect data. The Minimum Description Length principle is used for selection between possible worlds and determining appropriate levels of additional justification. A new encoding scheme allows the use of MDL within the framework of Inductive Logic Programming. Examples must be stored to provide additional justification for revisions without violating resource requirements. A new algorithm determines when to discard examples, minimising total usage while ensuring sufficient storage for justifications. Searching for revisions is the most computationally expensive part of the process, yet not all searches are successful. Another new algorithm uses a notion of theory stability as a guide to occasionally disallow entire searches to reduce overall time. The approach has been implemented as a learner called NILE. Empirical tests include two challenging domains where this type of learner acts as one component of a larger task. The first of these involves recognition of behavior activation conditions in another agent as part of an opponent modeling task. The second, more challenging task is learning to identify objects in visual images by recognising relationships between image features. These experiments highlight NILE'S strengths and limitations as well as providing new n domains for future work in ILP.

The objective of the dissertation was to assess the suitability of the scientific literacy development by using learning tasks in chemistry classes for ISCED 2. By comparing the learning tasks types in commercial workbooks and in the international assessment PISA, a significant difference in their structure was found out. Although the Czech Republic has undertaken to participate in the PISA project, Czech teachers have a different type of teaching tasks commonly available in their workbooks than the pupils afterwards solve in the PISA project. PISA's released and author's learning tasks were compiled into authentic workbooks. They were used in chemistry classes during the school year 2016/2017. Based on the pupils' results in the final assignments, all groups of grammar school pupils from experimental groups achieved better results in solving multicomponent learning tasks than the control group. However, the results of elementary schools pupils were significantly worse at final test scores than at initial ones, which was explained by the entire loss of their motivation to study. Pupils rated motivation to work with multicomponent tasks above average. They were fully aware of the importance and usefulness of solving multicomponent learning tasks, and, therefore, they solved them with proper...

Researchers have explored how different balances of first language (L1) and target language (TL) use in a foreign language classroom impact students' fluency and proficiency in TL acquisition. Research has shown that the use of the L1 in a foreign language classroom is done in order to determine the most effective way to raise the proficiency of second language learners to the level that is expected within their classrooms (Lee & Muncie, 2006). The use of the L1 is not something that is uncommon, even in the highest levels of foreign language instruction, although some believe it could inhibit learner growth in target language (TL) acquisition (Tanveer, 2007). Some scholars contend that there is a place for the L1 to be used in a second language classroom, rather than relying on complete usage of the TL (Biggs, 1999). Results have been mixed when it comes to whether or not the L1 should be used as much as the TL, and studies have seldom investigated what students and teachers believe regarding that matter. To this end, the present study examines the impact of the use of the L1 vs the use of the TL on 50 students at different levels in the French language classroom. Subjects were all enrolled in French classes ranging from the 101-level to the 201-level, and the 8 student instructors teaching these levels also participated in this study. Both a student survey and a teacher survey were administered at the end of the semester in order to look at the use of the TL vs the use of the L1 among students and teachers in their classrooms. Results show that the utilization of the L1 in foreign language classrooms is preferred by the students but that it is not fully justified. Numerous proponents of L1 use (Atkinson, 1987; Cook 2001; Swain & Lapkin, 2000; Wells, 1999) have cautioned against excessive use, instead recommending that it be used judiciously, and according to learner need. Future researchers might consider surveying students who are learning in an environment where L1 use is similar to student demand on this survey (very high, especially for things like giving instructions), as well as surveying students who are exclusively using TL in their learning environment.

The aim of the thesis is based on the existing approaches to the assessment of the difficulty of the task of teaching with a focus on ICT and computer science to design a methodology for determining the difficulty of the task and verify it on the model examples for elementary schools. The methodology will be to respond to the theoretical background, which are based, in particular, of the parameters, forms, functions, and the specifics of teaching jobs. Other theoretical basis for the analysis of the teaching jobs are from the known taxonomies, Focus group research method and statistical data processing. The empirical part qualitative research including the multi-round testing pupils Elementary school and the analysis of the data obtained.

Ce travail a pour principal objet d’étude la dynamique sociale développée dans le cadre des activités d’apprentissage des langues en ligne en contexte institutionnel. En s’appuyant sur les propositions faites par la théorie de l’activité, cette thèse présente une analyse de la finalité, du cadre instrumental et du cadre social de l’activité d’apprentissage des langues en ligne en contexte institutionnel et de leur évolution dans le système de l’activité.Cette recherche fournit également une méthode d’analyse permettant d’évaluer l’impact de différents types de tâches et d’environnements virtuels d’apprentissage sur l’intensité de la dynamique sociale développée au sein des groupes d’apprenants d’une langue en ligne en contexte institutionnel. La méthode d’analyse utilisée s’appuie aussi bien sur l’analyse quantitative des traces écrites des communications/productions des apprenants que sur l’analyse du contenu de ces traces.Nous montrons qu’il est possible de développer une dynamique sociale de communauté virtuelle au sein de groupes d’apprenants d’une langue en ligne en contexte institutionnel. Le développement d’une telle dynamique est favorisé par la mise en œuvre de tâches d’apprentissage des langues et d’environnements virtuels d’apprentissage permettant l’action sociale authentique dans des cadres sociaux qui dépassent le cadre formel de l’institution éducative. / Drawing on the proposals made by the activity theory, in this study, we considered learning as a conscious act directed toward a goal. This goal can be achieved through the use of appropriate artifacts and the participation of the individual within a social community. In this perspective, we studied the purpose, the instrumental framework and the social framework of online language learning activities in institutional context and their evolutions in the activity system.We showed that the evolution of the purpose of the act of language learning (development of language competence) inevitably involves the evolution of educational artifacts (language learning tasks), that of technical artifacts (virtual learning environments), as well as the nature of the social dynamics of the learning activity.We particularly focused on social dynamics developed in online language learning activities in the institutional context. In this perspective, we conducted a field study to analyze the intensity of the social dynamics developed through three learning activities involving three different combinations of tasks and virtual environments. The results of the field study confirmed the theoretical foundation of our thesis. Indeed, the types of tasks and virtual learning environments that we presented in the theoretical part as consistent with learning through authentic social action proved to promote significantly more intense social dynamics in the specific context of our field study.
