Student participation in peer interaction

2021

This study explores how students deal with material resources in their peer interaction when working in pairs in an open-ended problem-solving task. The productive use of material resources can be expected to support successful peer work. However, research into social phenomena in peer interaction is needed in order to identify and describe productive and less productive forms of dealing with material resources as students participate in open-ended problem-solving tasks. Consequently, this explorative study responds to this research need. Based on multimodal data, including video recordings, transcribed talk and the written contributions from four pairs of Year 7 students aged 12-13 years, …

A probabilistic long‐term framework for site‐specific erosion analysis of wind turbine blades: A case study of 31 Dutch sites

2021

Abstract Rain‐induced leading‐edge erosion (LEE) of wind turbine blades (WTBs) is associated with high repair and maintenance costs. The effects of LEE can be triggered in less than 1 to 2 years for some wind turbine sites, whereas it may take several years for others. In addition, the growth of erosion may also differ for different blades and turbines operating at the same site. Hence, LEE is a site‐ and turbine‐specific problem. In this paper, we propose a probabilistic long‐term framework for assessing site‐specific lifetime of a WTB coating system. Case studies are presented for 1.5 and 10 MW wind turbines, where geographic bubble charts for the leading‐edge lifetime and number of repai…

La Mediterrania: La Nostra Mar

1985

En 1984 organicé como director general de la Generalitat Valenciana los primeros encuentros sobre «La Mediterrania: La Nostra Mar», los días 28 y 29 de junio de 1984 en Valencia, como continuación de la campaña de difusión y concienciación sobre la situación del Mar Mediterráneo, iniciada con motivo de la celebración del Dia Mundial del Medio Ambiente, el 5 de junio. Como es bien conocido, esta fecha concreta fue elegida porque el 5 de junio de 1972 comenzó en Estocolmo la Conferencia de las Naciones Unidas sobre el Medio ambiente. Fruto de esta conferencia fue la creación del Programa de las Naciones Unidas para el Medio Ambiente (P.N.U.M.A.), con sede administrativa en Nairobi, que incluy…

Motivational predictors of students' participation in out-of-school learning activities and academic attainment in science : An application of the tr…

2018

Abstract Given the shortfall in students studying science, promotion of motivation and engagement in science education is a priority. The current study applied the trans-contextual model to study the motivational predictors of participation in science learning activities in secondary-school students . In a three-wave design, secondary-school students completed measures of perceived autonomy support, autonomous and controlled motivation, social-cognitive beliefs (attitudes, subjective norms, perceived control), intentions, and self-reported participation in out-of-school science learning activities. Five-weeks later, students self-reported their science learning activities. Students' science…

The relationship between behavior problems, gender, special education status and school performance in the early grades of school

2017

Liukkonen, Taru. 2017. The relationship between behavior problems, gender, special education status and school performance in the early grades of school. Master’s thesis in special education. University of Jyväskylä. Department of Education and Psychology. 41 pages. The purpose of this master’s thesis was to find out whether there are changes in the average level of behavior problems of pupils from 1st to 2nd grade and wheth-er gender or receiving part-time special education is related to the average level or possible change in behavior problems. Furthermore this study tested wheth-er behavior problems in the 1st grade predict the school performance in reading, writing and mathematics in th…

Visual cues improve students’ understanding of divergence and curl: Evidence from eye movements during reading and problem solving

2019

The coordination of multiple external representations is important for learning, but yet a difficult task for students, requiring instructional support. The subject in this study covers a typical relation in physics between abstract mathematical equations (definitions of divergence and curl) and a visual representation (vector field plot). To support the connection across both representations, two instructions with written explanations, equations, and visual representations (differing only in the presence of visual cues) were designed and their impact on students’ performance was tested. We captured students’ eye movements while they processed the written instruction and solved subsequent c…

Pair interactions in online assessments of collaborative problem solving: case-based portraits

2018

This exploratory case study focuses on how pairs of students can build a shared understanding and acquire collaborative problem-solving (CPS) practices during an online assessment of CPS skills, which is seen in the context of the CPS construct, in a symmetrical and asymmetrical task type. Even though CPS is widely recognised as a core twenty-first-century competency, its nature is not yet well understood. Also, until recently, most of studies have focused on the individual’s solution to a problem or on the skills individuals bring into a problem-solving space. This study extends from an individual- to group-level focus in CPS, emphasising the role and quality of the social aspects in CPS p…

Verbal counting skill predicts later math performance and difficulties in middle school

2019

This study examined the role of verbal counting skill as an early predictor of math performance and difficulties (at or below −1.5 standard deviation in basic math skills) in middle school. The role of fourth-grade level arithmetical skills (i.e., calculation fluency, multi-digit arithmetic i.e. procedural calculation, and word problem solving) as mediators was also investigated. The participants included 207 children in central Finland who were studied from kindergarten to the seventh grade. Path modeling showed that verbal counting in kindergarten is a strong predictor for basic math performance in seventh grade, explaining even 52% of the variance in these skills after controlling for th…

Olika profiler för exekutiva färdigheter bland elever i behov av stöd

2022

Svårigheter med exekutiva färdigheter är relativt vanliga i skolan och påverkar elevers arbetssätt och inlärning negativt. Kunskap om individuella uttryck av exekutiva svårigheter och beteende i skolan ger en bättre utgångspunkt för att planera och genomföra riktade och effektiva stödåtgärder. I den här studien fokuserar vi på hurdana olika profiler det finns gällande de exekutiva svårigheterna bland elever som erbjuds specialpedagogiskt stöd för koncentrationssvårigheter, samt hur dessa är relaterade till beteendeproblem, positivt socialt beteende och akademiska grundfärdigheter. I den här studien deltog 183 elever från två kohorter (medelålder = 9,57 år; modersmål svenska = 62,8 %, finska…
