Reconfigurations in sustainability transitions : a systematic and critical review
2021
Two streams of literature have become especially prominent in understanding social change toward sustainability within the past decades: the research on socio-technical transitions and applications of social practice theory. The aim of this article is to contribute to efforts to create dialogue between these two approaches. We do this by focusing on the concept of reconfiguration, which has become a much-used, but poorly defined notion in the discussion on sustainability transitions. To understand what is defined as reconfiguration in systems and practices, and how the understanding of reconfiguration in regimes could benefit from insights about reconfiguration in practices, we conducted a …
Physical Activity, Sedentary Behavior, and Academic Performance in Finnish Children
2013
Purpose: This study aimed to determine the relationships between objectively measured and self-reported physical activity, sedentary behavior, and academic performance in Finnish children. Methods: Two hundred and seventy-seven children from five schools in the Jyväskylä school district in Finland (58% of the 475 eligible students, mean age = 12.2 yr, 56% girls) participated in the study in the spring of 2011. Self-reported physical activity and screen time were evaluated with questions used in the WHO Health Behavior in School-Aged Children study. Children’s physical activity and sedentary time were measured objectively by using an ActiGraph GT1M/GT3X accelerometer for seven consecutive da…
Individual differences in processes of lifestyle changes among people with obesity: an acceptance and commitment therapy (ACT) intervention in a prim…
2020
Abstract Aim: To explore what thoughts, feelings, and learning processes were involved in obese participants’ lifestyle change during an acceptance and commitment therapy (ACT) lifestyle intervention delivered in primary health care. Background: Previous studies have revealed that lifestyle interventions are effective at promoting initial weight loss, but reduced weight is often difficult to sustain because of the failure to maintain healthy lifestyle changes. Achieving and maintaining lifestyle changes requires to learn self-regulation skills. ACT-based lifestyle interventions combine many self-regulatory skill factors, and the results from previous studies are promising. Research on the i…
3.13 Carbohydrate Derived Auxiliaries: Amino Sugar and Glycosylamine Auxiliaries
2012
The stereodifferentiating potential of carbohydrate auxiliaries is illustrated by examples of oxazolidinones derived from amino sugars and aldimines of glycosylamines. Taking advantage of the bicyclic structure of amino sugar-derived oxazolidinones, reactions of their unsaturated or deprotonated N -acyl derivatives show an efficient exo - versus endo -differentiation. High diastereoselectivity is achieved in the syntheses of β -branched or α -substituted carboxylic acid derivatives. Imines of glycosylamines, in particular of 2,3,4,6-tetra- O -pivaloyl- β - d -galactopyranosylamine, are characterized by a conformation stabilized through the exo -anomeric effect and by their ability to coordi…
Supporting struggling readers with digital game-based learning
2019
This study investigates the effectiveness of a digital game—GraphoLearn (GL)—in supporting second-grade students who have persistent difficulties with acquiring accurate and fluent reading skills. The participants (N = 37) were randomly assigned either to a 6-week intervention including sessions with GL, in addition to school-provided support, or a control group receiving only school-provided support. The intervention took place at the students’ homes and schools under the supervision of their parents and teachers. The results showed that the children who received the GL intervention developed significantly faster in word reading than the control group. Moreover, their reading development w…
Assessing the effectiveness of a game‐based phonics intervention for first and second grade English language learners in India: A randomized controll…
2021
Background In 2018, it was found that only a quarter of Grade 3 children in India were reading at grade level. A growing demand for English education has further limited children's literacy achievement. Despite a strong evidence base in favour of using systematic phonics for building English literacy skills, many teachers in India continue to use rote-methods of literacy instruction. Objectives We aimed to examine the efficacy of GraphoLearn (GL) English Rime, a computer-assisted reading intervention, in improving the foundational literacy skills of 1st and 2nd grade students who were attending an English medium school in India. Methods A total of 136 students across 6 classrooms were rando…
A mobile game as a support tool for children with severe difficulties in reading and spelling
2020
We used a randomized controlled trial to investigate if a mobile game, GraphoLearn (GL), could effectively support the learning of first graders (N = 70), who have severe difficulties in reading and spelling. We studied the effects of two versions of the game: GL Reading, which focused on training letter-sound correspondence and word reading; and GL Spelling, which included additional training in phonological skills and spelling. During the spring of first grade, the children trained with tablet computers which they could carry with them during the six-week intervention. The average exposure time to training was 5 hr 44 min. The results revealed no differences in the development of reading …
Assessing the effectiveness of GraphoLearn combined with classroom instruction on phonics : a randomised control trial
2023
Proficiency in reading is a gateway for learning. However, the literacy rate in India stands at only 73% today. Many children studying in English-medium public schools often face a learning disadvantage through the schooling years since they struggle in learning to read in English which manifests into a struggle with reading to learn in later years. This disadvantage is more pronounced in children living in poverty. Thus, consistent efforts towards building foundational literacy skills of these children when developmentally appropriate is important to overcome the learning crisis. The aim of this study was to determine whether GraphoLearn, a computer assisted learning tool, combined with Gr…
GraphoLearn India : The Effectiveness of a Computer-Assisted Reading Intervention in Supporting Struggling Readers of English
2018
India, a country with a population of more than 1.3 billion individuals, houses the world’s second largest educational system. Despite this, 100 of millions of individuals in India are still illiterate. As English medium education sweeps the country, many are forced to learn in a language which is foreign to them. Those living in poverty further struggle to learn English as it tends to be a language which they have no prior exposure to and no support at home for. Low-quality schools and poor instructional methods further exacerbate the problem. Without access to quality education, these individuals continue to struggle and are ultimately never given the chance to break the cycle of poverty.…
Game learning analytics for understanding reading skills in transparent writing system
2020
Serious games are designed to improve learning instead of providing only entertainment. Serious games analytics can be used for understanding and enhancing the quality of learning with serious games. One challenge in developing computerized support for learning is that learning of skills varies between players. Appropriate algorithms are needed for analyzing the performance of individual players. This paper presents a novel clustering-based profiling method for analyzing serious games learners. GraphoLearn, a game for training connections between speech sounds and letters, serves as the game-based learning environment. The proposed clustering method was designed to group the learners into p…
