Online Research and Comprehension Performance Profiles Among Sixth-Grade Students, Including Those with Reading Difficulties and/or Attention and Exe…

2022

This study identified online research and comprehension (ORC) performance profiles of 436 sixth-grade students (206 girls) aged 12–13 years. We included learner groups with different learning-related difficulties and explored how students’ reading habits were represented in various performance profiles. First, students’ ORC performance was examined with a validated web-based assessment measuring their skills in locating, evaluating, synthesizing, and communicating information. Second, reading fluency and teacher-rated attention and executive function (EF) difficulty scores were used to form learner groups: (1) students with reading difficulties, (2) students with attention and EF difficulti…

Literacy Skills and Online Research and Comprehension : Struggling Readers Face Difficulties

2019

The present study evaluated the extent to which literacy skills (reading fluency, written spelling, and reading comprehension), together with nonverbal reasoning, prior knowledge, and gender, are related to students’ online research and comprehension (ORC) performance. The ORC skills of 426 sixth graders were measured using a Finnish adaptation of the Online Research and Comprehension Assessment. Results of a structural equation model showed that these ORC skills were divided into six highly correlated factors, and that they formed a common factor in ORC. Altogether, these predictor variables explained 57% of the variance in ORC. Reading comprehension, along with gender, was the strongest p…

Teaching sourcing during online inquiry – adolescents with the weakest skills benefited the most

2022

AbstractSourcing - identifying, evaluating, and using information about the sources of information - assists readers in determining what to trust when seeking information on the Internet. To survive in the post-truth era, students should be equipped with sufficient sourcing skills. This study investigated the efficacy of a teacher-led intervention aimed at fostering upper secondary school students’ (N = 365) sourcing during online inquiry. The intervention (4 × 75 min) was structured in accordance with the phases of online inquiry: locating, evaluating, synthesizing, and communicating information. During the intervention, teachers demonstrated why and how to source, and students practiced s…

Lääkevalmisteet ja ravintolisät suomalaisessa kilpaurheilussa

2016

Koponen, M. 2016. Lääkevalmisteet ja ravintolisät suomalaisessa kilpaurheilussa. Terveystieteiden laitos, Jyväskylän yliopisto, liikuntalääketieteen pro gradu -tutkielma, 56 s, 5 liitettä. Aikaisemmat tutkimukset ovat osoittaneet lääkevalmisteiden ja ravintolisien käytön olevan yleistä kilpaurheilijoiden keskuudessa. Tutkimusaineistoa on kerätty haastattelemalla, semistrukturoiduilla kyselylomakkeilla sekä Olympialaisissa dopingtestauksen yhteydessä myös dopingtestipöytäkirjoista. Suomessa dopingtestipöytäkirjoja ei ollut aikaisemmin käytetty tutkimusaineistona. Tämän tutkimuksen tarkoituksena oli selvittää suomalaisten kilpaurheilijoiden lääkevalmisteiden ja ravintolisien käyttöä vuonna 20…

Bilateral activations in operculo‐insular area show temporal dissociation after peripheral electrical stimulation in healthy adults

2018

Interhemispheric transfer is necessary for sensory integration and coordination of body sides. We studied how somatosensory input from one body side may reach both body sides. First, we investigated with 17 healthy adults in which uni‐ and bilateral brain areas were involved in consecutive stages of automatic sensory processing of non‐nociceptive peripheral stimulation. Somatosensory evoked fields (SEFs) to electrical stimulation were recorded with 306‐channel magnetoencephalography in two conditions. First, SEFs were registered following sensory radial nerve (RN) stimulation to dorsal surface of the right hand and second, following median nerve (MN) stimulation at the right wrist. Cortical…

More comprehensive proprioceptive stimulation of the hand amplifies its cortical processing

2021

Corticokinematic coherence (CKC) quantifies the phase coupling between limb kinematics and cortical neurophysiological signals reflecting proprioceptive feedback to the primary sensorimotor (SM1) cortex. We studied whether the CKC strength or cortical source location differs between proprioceptive stimulation (i.e., actuator-evoked movements) of right-hand digits (index, middle, ring, and little). Twenty-one volunteers participated in magnetoencephalography measurements during which three conditions were tested: 1) simultaneous stimulation of all four fingers at the same frequency, 2) stimulation of each finger separately at the same frequency, and 3) simultaneous stimulation of the fingers…

Magnetoencephalography Responses to Unpredictable and Predictable Rare Somatosensory Stimuli in Healthy Adult Humans

2021

Mismatch brain responses to unpredicted rare stimuli are suggested to be a neural indicator of prediction error, but this has rarely been studied in the somatosensory modality. Here, we investigated how the brain responds to unpredictable and predictable rare events. Magnetoencephalography responses were measured in adults frequently presented with somatosensory stimuli (FRE) that were occasionally replaced by two consecutively presented rare stimuli [unpredictable rare stimulus (UR) and predictable rare stimulus (PR); p = 0.1 for each]. The FRE and PR were electrical stimulations administered to either the little finger or the forefinger in a counterbalanced manner between the two conditio…

Promoting sixth graders’ credibility evaluation of Web pages: An intervention study

2020

Abstract This study investigated whether a teacher-led intervention program on online inquiry improved sixth graders' performance in a credibility evaluation task. Students (N = 342) were divided into two conditions, an intervention group (190 students) and a control group (152 students). The intervention program (21 × 45 min lessons) was implemented during a six-week course as a part of normal schoolwork. The program included explicit teaching of online inquiry skills: searching for information (3 lessons), evaluating credibility of information (3 lessons), and synthesizing information (3 lessons). In addition, the skills taught were applied in two online inquiry projects comprising 12 les…
