Solar PV Powered Air Conditioner Analysis for an Office/Classroom in a Tropical Climate

This thesis focuses on using photovoltaic produced electricity to power air conditioners in a tropical climate. The study takes place in Surabaya, Indonesia at two different locations the classroom, located at the UBAYA campus and the home office, 10 km away. Indonesia has an average solar irradiation of about 4.8 kWh/m²/day (PWC Indonesia, 2013) which is for ideal conditions for these tests. At the home office, tests were conducted on different photovoltaic systems. A series of measuring devices recorded the performance of the 800 W PV system and the consumption of the 1.35 kW air conditioner (cooling capacity). To have an off grid system many of the components need to be oversized. The inverter has to be oversized to meet the startup load of the air conditioner, which can be 3 to 8 times the operating power (Rozenblat, 2013). High energy consumption of the air conditioner would require a large battery storage to provide one day of autonomy. The PV systems output must at least match the consumption of the air conditioner. A grid connect system provides a much better solution with the 800 W PV system providing 80 % of the 3.5 kWh load of the air conditioner, the other 20 % coming from the grid during periods of low irradiation. In this system the startup load is provided by the grid so the inverter does not need to be oversized. With the grid-connected system, the PV panel’s production does not need to match the consumption of the air conditioner, although a smaller PV array will mean a smaller percentage of the load will be covered by PV. Using the results from the home office tests and results from measurements made in the classroom. Two different PV systems (8 kW and 12 kW) were simulated to power both the current air conditioners (COP 2.78) and new air conditioners (COP 4.0). The payback period of the systems can vary greatly depending on if a feed in tariff is awarded or not. If the feed in tariff is awarded the best system is the 12 kW system, with a payback period of 4.3 years and a levelized cost of energy at -3,334 IDR/kWh. If the feed in tariff is not granted then the 8 kW system is the best choice with a lower payback period and lower levelized cost of energy than the 12 kW system under the same conditions.

Motivation genom sponsring : En studie som utvärderar sponsringens möjligheter till ökad motivation bland personalen i en organisation

Sponsring är ett utbyte och en marknadsföringsmetod som används av allt fler organisationer. Med syftet att påverka personalen i en organisation är sponsring en relativt oanvänd metod för marknadsföring. Trots detta så påverkar sponsring personalen oavsett organisationens målsättning med sponsring. Syftet med studien är att utvärdera om sponsring fungerar som ett verktyg för motivation i en specifik organisation, sedan utvärderas hur sponsring bidrar till motivation. För att besvara syftet genomfördes en kvantitativ studie i form av en enkätundersökning. Denna genomfördes hos vårt studieobjekt Länsförsäkringar i Gävleborg. Analysen av den insamlade datan har genomförts med stöd av den teoretiska referensramen. Resultatet av studien visar att sponsring kan användas till att motivera personalen på Länsförsäkringar. Dock så är organisationens nuvarande sponsring något som inte tydligt motiverar personalen. Länsförsäkringar vill med sin sponsring bidra till samhället och på så sätt skapa engagemang och stolthet bland personalen. Sponsring får personalen att känna stolthet men däremot inget tydligt engagemang. Länsförsäkringar är bra på att informera personalen om sponsring, däremot så är organisationen inte lika bra på att lyssna till personalens värderingar kring sponsring. Det bristande engagemanget skulle då kunna bero på att personalen inte får tycka till om organisationens sponsring.

Abilities and Cultural Understanding through Literature in the EFL Classroom : - A Literature Review

The English language can be seen as a lingua franca of contemporary times. Its spread and use in the globalized world has affected most levels of society and it can be argued that, in current times, English is synonymous with communication. This need for communication has shaped the English as a Foreign Language (EFL) syllabus, which is evident in the Swedish national steering documents for the educational system. For the upper secondary school these documents show an emphasis on communication, on cultural understanding, and also on the use of literature within the EFL classroom. The need to possess communicative abilities and cultural understanding, in connection with the use of literature, has sparked an interest to investigate if and how literature itself can be used as a tool to develop and improve EFL students’ communicative skills and cultural understanding. This literature review thesis analyzes five international research articles from different geographical parts of the Globe. The findings are categorized, compared, synthesized, and finally discussed in order to answer the research questions asked, and also compared with the English subject syllabus for the Swedish upper secondary school. The findings indicate that the analyzed articles share a consensus, to a varied degree, regarding the positive aspects of literature use in the EFL setting. The arguments are that communicative skills and cultural understanding are intertwined - enabling each other to exist, develop, and improve. One cannot exist fully without the other, and literature is a good tool to use to develop and improve these abilities. Literature can help develop all skills needed to acquire and produce both written and spoken English, and it also enables cultural understanding and a broadening of the mind. Where the articles differ somewhat is in the ideas of why literature is a good tool, how to implement literature in the classrooms, and what some of the negative aspects might be. The thesis also brings the lack of Swedish studies within EFL to the readers’ attention, as well as the need to do more research focusing on the students’ perspectives towards literature use in the EFL setting.

Reading That Matters : A Literature Review on Meaningful Reading Experiences in the EFL Classroom

This thesis is a literature review on literature reading in the English as a Foreign Language (EFL) and the English as a Second Language (ESL) classroom, of mainly upper secondary schools. The underlying objective for this work is that meaningful reading experiences can have a positive impact on a developing young individual on his or her way into adulthood. The aim of this thesis is to explore what theories and methods are used when trying to create prerequisites for meaningful reading experiences, and how these experiences actually are realized. Qualitative methods are mainly used, except for a small section of the methodology of finding the sources, which is quantitative in nature. Since very little previous research has been done in the field, the six sources used in this review are internationally spread over five continents. They are mainly analyzed from a theoretical background of reader response and critical literacy perspectives. The main findings show that a number of theoretical approaches and methodologies can be useful in creating meaningful reading experiences. What may have proven most effective was addressing actual problems in the students’ everyday lives through applied critical literacy.

Läsundervisningens organisation i grundskolans tidiga årskurser : En systematisk litteraturstudie om hur lärare i årskurserna F-3 arbetar för att utveckla elevers läsförmåga.

Syftet med denna litteraturstudie var att undersöka hur F-3 lärare organiserar och bedriverden tidiga läsundervisningen samt undersöka vilka faktorer som verkar påverkaundervisningen och dess innehåll. Metoden för arbetet är en systematisk litteraturstudie därtidigare empiriska forskningar har analyserats och presenterats. Litteraturen söktes genomsöktjänster och databaser tillgängliga via Högskolan Dalarnas bibliotek i form av LIBRISoch SUMMON. Resultatet visar att lärare ser avkodning och läsförståelse som viktiga delardå eleverna ska utveckla en god läsförmåga. Hur lärarna organiserar den tidigaläsundervisningen ser dock ut på olika sätt. Några olika läsinlärningsteorier speglas ilärarnas sätt att bedriva undervisningen men den främsta metoden verkar dock vara dentraditionella ljudningsmetoden där eleverna i ett tidigt stadium lär sig ords enskildabeståndsdelar. Något som verkar vara generellt i skolorna är att många lärare anordnartidiga läsförberedande aktiviteter för de yngre eleverna där de får möta skriftspråket ilekfulla former. Lärarens kunskaper inom läsinlärningsområdet visas vara en avgörandefaktor för den tidiga läsundervisningen och barnens utveckling av en god läsförmåga.

Swedish Primary Teachers' Attitudes towards Integrating Gaming in the EFL Classroom

A current topic in Swedish schools is the use of computer games and gaming. One reason is because computers are becoming more and more integrated into the schools, and the technology plays a large role in the everyday lives of the pupils. Since teachers should integrate pupils’ interests in the formal teaching, it is of interest to know what attitudes teachers have towards gaming. Therefore the aim of this empirical study is to gain an insight into the attitudes Swedish primary teachers have towards online and offline computer games in the EFL classroom. An additional aim is to investigate to what extent teachers use games. Five interviews were conducted with teachers in different Swedish schools in a small to medium-sized municipality. After the interviews were transcribed, the results were analyzed and discussed in relation to relevant research and the sociocultural theory. The results show that teachers are positive towards games and gaming, mostly because gaming often contains interaction with others and learning from peers is a main component in sociocultural theory. However, only one out of the five participants had at some point used games. The conclusion is that teachers are unsure about how to use games in their teaching and that training and courses in this area would be valuable. More research is needed within this area, and it would be of value to investigate what suggested courses would contain and also to investigate exactly how games can be used in teaching.

Learning by Reading : A literature study on the use of authentic texts in the EFL upper elementary classroom

The English language is widely used throughout the world and has become a core subject in many countries, especially for students in the upper elementary classroom. While textbooks have been the preferred EFL teaching method for a long time, this belief has seemingly changed within the last few years. Therefore, this study looks at what prior research says about the use of authentic texts in the EFL upper elementary classroom with an aim to answer research questions on how teachers can work with authentic texts, what the potential benefits of using authentic texts are and what teachers and students say about the use of authentic texts in the EFL classroom. While this thesis is written from a Swedish perspective, it is recognized that many countries teach EFL. Therefore, international results have also been taken into consideration and seven previous research studies have been analyzed in order to gain a better understanding of the use of authentic texts in the EFL classroom. Results indicate that the use of authentic texts is beneficial in teaching EFL. However, many teachers are still reluctant to use these, mainly because of time constraints and the belief that such texts are too difficult for their students. Since these findings are mainly focused on areas outside of Sweden, additional research is needed before conclusions can be drawn on the use of authentic texts in the Swedish upper elementary EFL classroom.

English as the target language : A literature study on teachers’ and L2 learners’ language use in the upper elementary classroom

Even though English is a subject where Swedish pupils do well compared to pupils in other countries, research indicates that pupils are not always motivated to learn in the English classroom. Therefore, the aim of this study is to find research relating to the use of the target language in classrooms for pupils at the upper elementary level, particularly language learners in Sweden. The focus of this thesis is to find out what benefits and challenges accompany the use of the target language during English lessons, as well as what pupils’ opinions are on the consistent use of the target language in the classroom. This literature review of five research articles shows that it is beneficial for pupils’ language development to have lessons where mainly the target language is used. It is for example beneficial for pupils’ ability to speak, their pronunciation, vocabulary and ability to use language strategies. The results show that there are challenges as well, especially for the teachers, since use of the target language presumes that the teacher has good language skills and is capable of scaffolding each pupil at their individual level and in their zone of proximal development. Furthermore, there are challenges like differences in pupils’ skill level, creating tasks that both motivate and stimulate, and creating a safe learning environment. Even though the results in this thesis are limited, it is still obvious that it is an important area, where more research is necessary in order to assist teachers in how to teach English as effectively as possible.

The power of literature : A literature review on the incorporation of children’s literature in the lower-elementary English as a Second- Language classroom.

The use of children’s literature in the English as a Second language (ESL) classroom is a widely used teaching method. This study aims to find research relating to the incorporation of children’s literature in the lower elementary English as a secondlanguage classroom. The main questions are how children’s literature can be used in the classroom and what potential benefits it has. A systematic literature review was carried out and research from six studies was included. The included studies, analyzed in this thesis, involved children aged 6-9, who are learning a second language. The results reveal multiple benefits with the use of children’s literature in the lower elementary ESL classroom, such as vocabulary gains, improved speaking and listening skills, increased motivation and better pronunciation. The results also present a few suggestions on how to incorporate the literature in the classroom, where reading aloud to the students appears to be the most common practice. It also appears common to have post-reading sessions that include discussions about what has been read.

Students’ Perspectives on Extensive Literature : Using Literature to Enhance Communicative Competence and Cultural Understanding in the EFL-Classroom

The aim of this thesis is to investigate the use of literature within the Swedish Upper Secondary EFL-classroom from the students’ perspective. How do the students in the study relate to literature and its use to enhance and enable their communicative competence and cultural understanding? Also, how do their answers compare with their teacher’s and the adult perspectives and findings from previous international research? The empirical data obtained from the study has been analysed from the perspectives of sociocultural and motivational theory, and the findings show that the participating students believe literature to be a good didactic tool to apply in the EFL-classroom, both in order to enhance their communicative competence and their cultural understanding. The students prefer to have a sociocultural approach to their literature-learning, with group-discussions of various sizes. The key for the students in this respect is interesting, relevant and engaging subject-matter, as well as a positive and motivational teacher. The responses given by the students correlate with those given by their teacher as well as previous international research. The students regard literature as a way of gaining new perspectives, as well as experiencing language in use. Where they diverge somewhat from the international research is in regard to literature’s use for enhancing their competence to speak in class, and that some students seem to think that communication and cultural understanding are separable. Future studies within this field might include the conducting of a larger and more in-depth survey regarding the students’ ideas about literature, culture and communication. Why do so many of the student respondents neither agree nor disagree with the statement concerning communication and cultural understanding being inseparable? This can be an important issue to investigate in today’s global climate of cross-cultural and intercultural experiences, especially in view of the political climate of diverse attitudes towards refugees, immigrants and emigration

An Empirical Study on Teachers’ Choice of Extensive Literature in the Swedish Upper Secondary EFL Classroom

The importance of extensive literature reading in the English as a Foreign Language (EFL) context has been given increasing attention in recent research. Literature reading is also a required part of the national syllabi of the (EFL) courses offered to both adolescents and adults at Upper Secondary level in Sweden. This thesis aims to investigate the teachers’ process of making literature choices for extensive reading in upper secondary EFL courses in Sweden. Eight teachers of three different student groups took part in the study, representing adolescent university preparatory programs and vocational programs, as well as programs for adult students. Questionnaires were used and the data was analyzed for patterns revealing three main factors affecting teachers’ literature choice: language proficiency, reading experience and contextual factors. These three factors were fitted into the theoretical framework of psycholinguistic and sociolinguistic reading models, with the addition of a perspective of motivational research. The results of this survey underline the importance of extensive reading, according to teachers, and that motivation for literature choice can be primarily related to factors associated with psycholinguistic reading models. The survey also points to the need for further investigating of teachers’ own experiences of literature reading, searching for deeper motivational factors which influence teaching choices. Another future field of research is the choice of reading activities assigned together with the chosen literature, which probably also influence teachers’ choices in the Swedish EFL classroom.

L1 Use in the EFL-classroom : A Literature Review on Teachers’ Use of the L1 in the EFL-classroom on Upper Secondary Level

Even though English should mainly be used in the EFL-classroom according to the Swedish national curriculum, some recent scholars have argued that a judicious use of the students’ L1 by the teachers in some particular situations may benefit the learning environment there. From this context, this thesis examines what research says about in what particular situations the L1 is used by teachers in upper secondary EFL-classrooms as well as the teachers’ and the students’ attitudes towards this practice. The method used was a systematic literature review, where seven articles from all across the globe were analyzed, compared and synthesized. The results show that the L1 was mainly used by the teachers when managing discipline, when explaining grammar and when teaching vocabulary. However, the articles did not conclude how the L1 could be used strategically by the teachers. Concerning the teachers’ and students’ attitudes, the majority of these were positive towards L1 use by the teacher in the above mentioned situations. However, the teachers were not aware of how the L1 could be used by them in a judicious and a strategic way. Lastly, it can be concluded that more research is needed on how the L1 can be used more strategically by the teachers as well as on the students’ perspective on this.

The Role of Motivational Strategies in the Upper Elementary Classroom : A systematic literature review about teacher strategies that promote self-confidence, motivation and a conducive learning environment

The aim of this literature review is to investigate which strategies teachers use to motivate pupils to communicate orally in English. The literature review also investigates how these teacher strategies affect pupils. The methodology used for this investigation is a systematic literature review. Various databases have been used when searching for literature. Scientific articles and theses have been searched for. They have also been read and analyzed before they have become a part of this review. The results indicate that some teachers feel insecure when speaking English. Therefore Swedish is spoken in many language classrooms. Teachers speaking in front of the class is the traditional way of teaching, and it does not seem to be a strategy who influences pupils positively. If teachers speak the target language among pupils they often get more motivated and focused pupils who feel comfortable speaking English. Young pupils are fast learners. By exposing them to the English language in early ages they receive great opportunities to learn a foreign language and strengthen their self-confidence. Drama, songs and rhymes are preferable strategies to use when teaching young learners. What position teachers decide to take in the classroom is also a significant element when teaching foreign languages.

LVU -politikerns eller professionens beslut? : En studie som syftar att undersöka hur socialsekreterarna ser på sin roll i LVU-ärenden i en politiskt styrd organisation

Allt eftersom professionen tar allt större plats på den politiska arenan förändras politikernas roll vilket kan åsidosätta de demokratiska aspekterna. I studien tar vi oss an socialsekreteraren och åskådliggör dess komplexa yrkesroll i en politiskt styrd organisation vilket bidrar till svårigheter när beslut om LVU skall fattas. För att uppnå detta har kvantitativ metod i form av enkätfrågor använts. Resultatet visar att både politiker och tjänstemän har en hög tilltro till socialsekreterarens roll och dess beslutsfattande inom LVU. Socialsekreteraren anser att det är de som har inflytandet över och tar det avgörande besluten om LVU vilket även förstås då återremitteringar sällan sker.

Forskningscirkeln en arbetsform för att utveckla skolan mot en lärande organisationlärande organisation?

När samhället blir mera komplext ställs generellt sett allt större krav på enskilda individer och organisationer. Detta innebär också att t ex kraven på skolan som organisation ökar i motsva-rande grad. Om förändringar i skolan skall lyckas måste lärarna involveras (Hargreaves, 1998). Förändringen måste helt enkelt utgå från lärarna själva. “It is teachers who, in the end, will change the world of the school by understanding it“ (Lawrence Stenhouse, citerad i Egerbladh & Tiller, 1998). För många lärare är kärnpunkten när verksamheten skall förändras om den går att genomföra i praktiken. På det sätt som lärare förstår hur skolan fungerar kan även antas ha betydelse för hur de utför sina arbetsuppgifter. Det är mot en sådan bakgrund som s k forskningscirklar, som ett forum för ett möte mellan lärare och forskare, blir av intresse. Kan då också s k lärande organisationer innehålla forskningscirklar som en möjlig arbetsform för att både förstå och att utveckla skolans verksamhet i praktiken? Med utgångspunkt från den bakgrund som skisserats upp är syftet med detta paper sålunda att diskutera: a) Under vilka förutsättningar är det möjligt att tala om skolan som en lärande organisa-tion?b) Är det möjligt att betrakta forskningscirkeln som ett, av flera tänkbara, medel för att utveckla skolan mot en lärande organisation?Jag utgår från två av Senges (1995) huvudkriterier, personlig utveckling (Personal Mastery) och team-lärande, för att diskutera några aspekter av de frågeställningar som anges i syftet. För att ge en mer fullständig bild skulle det självfallet ha varit att föredra att de tre övriga kriterierna som Senge använder hade kunnat behandlas på ett motsvarande sätt. Jag väljer dock bort dessa då det inte finns möjlighet att klara av en sådan uppgift inom den begränsade ram som ett paper av den här typen ger utrymme för.
