Testa din inlärningsstil : En utredning om VAK i undervisning av det andra inhemska språket

This thesis is an investigation of the significance of VAK, i.e. the visual, auditory and kinaesthetic learning styles, for language education. The research part evaluates the predictive validity of a VAK test commonly used in Finnish education. The results of the test were compared, respectively, with the results of a visual, an auditory and a kinaesthetic word test. 62 dyslexic language leaners participated in the tests. There was no statistically significant link between the results of the VAK test and the word tests. On the grounds of a voluntary questionnaire, most of the students did however consider it important that they are taught according to their personal learning style: visual, auditory or kinaesthetic. One of the goals of the study was to investigate the theoretical background of VAK. VAK does not seem to have a consistent theoretical basis, but combines various elements such as NLP pedagogy and Dunn's and Prashnig's learning style models that have previously been sharply criticized by scholars. The study leaves it open whether individual learning styles do exist, and how they could be diagnosed.

Konstruktioner i interaktion. : de e som resurs i samtal

This study concerns the most common word pair in spoken Swedish, de e (it is, third person pronoun + copula-verb in present tense). The aim of the study is twofold, with an empirical aim and a theoretical aim. The empirical aim is to investigate if and how the string de e can be understood and described as a construction in its own right with characteristics that distinguishes it from other structures and resources in spoken Swedish. The theoretical aim is to test how two different linguistic theories and methods, interactional linguistics and construction grammar, can be combined and used to describe and explain patterns in languaging that traditional grammar does take into account. The empirical analysis is done within the interactional linguistic framework with sequence analyses of excerpts from authentic conversation data. The data consists of approximately ten hours of recorded conversation from Finland and Sweden. The sequence analysis suggests that the string de e really is used as a resource in its own right. In most cases, the string is also used in ways consistent with abstract grammatical patterns described by traditional grammar. Nevertheless, there are instances where de e is used in ways not described before: with numerals and infinitive phrases as complements, without any complements at all and together with certain complements (bra, de) in idiomatic ways. Furthermore, in the instances where de e is used according to known grammatical patterns the function of the particular string de e is clearly contextually specific and in various ways linked to the micro-context in which it is used. A new model is suggested for understanding and concluding the results from the sequence analyses. It consists of two different types of constructions grammatical and interactional. The grammatical constructions show how the string is used in eleven structurally different ways. The interactional constructions show seven different sequential positions and functions in which the string occurs. The two types of constructions are also linked to each other as potentials. This is a new way to describe how interactants use and responds to a concrete string like de e in conversation.

Using a botanic garden collection to test a bioclimatic vegetation scheme

Vegetation maps and bioclimatic zone classifications communicate the vegetation of an area and are used to explain how the environment regulates the occurrence of plants on large scales. Many practises and methods for dividing the world’s vegetation into smaller entities have been presented. Climatic parameters, floristic characteristics, or edaphic features have been relied upon as decisive factors, and plant species have been used as indicators for vegetation types or zones. Systems depicting vegetation patterns that mainly reflect climatic variation are termed ‘bioclimatic’ vegetation maps. Based on these it has been judged logical to deduce that plants moved between corresponding bioclimatic areas should thrive in the target location, whereas plants moved from a different zone should languish. This principle is routinely applied in forestry and horticulture but actual tests of the validity of bioclimatic maps in this sense seem scanty. In this study I tested the Finnish bioclimatic vegetation zone system (BZS). Relying on the plant collection of Helsinki University Botanic Garden’s Kumpula collection, which according to the BZS is situated at the northern limit of the hemiboreal zone, I aimed to test how the plants’ survival depends on their provenance. My expectation was that plants from the hemiboreal or southern boreal zones should do best in Kumpula, whereas plants from more southern and more northern zones should show progressively lower survival probabilities. I estimated probability of survival using collection database information of plant accessions of known wild origin grown in Kumpula since the mid 1990s, and logistic regression models. The total number of accessions I included in the analyses was 494. Because of problems with some accessions I chose to separately analyse a subset of the complete data, which included 379 accessions. I also analysed different growth forms separately in order to identify differences in probability of survival due to different life strategies. In most analyses accessions of temperate and hemiarctic origin showed lower survival probability than those originating from any of the boreal subzones, which among them exhibited rather evenly high probabilities. Exceptionally mild and wet winters during the study period may have killed off hemiarctic plants. Some winters may have been too harsh for temperate accessions. Trees behaved differently: they showed an almost steadily increasing survival probability from temperate to northern boreal origins. Various factors that could not be controlled for may have affected the results, some of which were difficult to interpret. This was the case in particular with herbs, for which the reliability of the analysis suffered because of difficulties in managing their curatorial data. In all, the results gave some support to the BZS, and especially its hierarchical zonation. However, I question the validity of the formulation of the hypothesis I tested since it may not be entirely justified by the BZS, which was designed for intercontinental comparison of vegetation zones, but not specifically for transcontinental provenance trials. I conclude that botanic gardens should pay due attention to information management and curational practices to ensure the widest possible applicability of their plant collections.
