Studentassistenten verrichten verschillende soorten onder-wijstaken in het hoger onderwijs. Deze systematische literatuurstudiebracht het onderzoek in kaart naar hoe studentassistenten worden voor-bereid op hun inzet in het onderwijs, welke soorten onderwijs ze ver-zorgen en wat dit oplevert voor de studentassistenten en hun studenten.De studentassistenten werden vooral bij praktisch vaardigheidsonder-wijs en laboratoriumonderwijs in medische en scheikundige opleidingeningezet, en in mindere mate ook bij casusonderwijs en studievaardig-heden. Qua voorbereiding hadden ze het meeste baat bij een trainingwaar het verwachte gedrag voorgedaan wordt, waar ze kunnen oefenenen hier feedback op krijgen. Wanneer onderwijs door studentassisten-ten als aanvulling op het bestaande onderwijs wordt georganiseerd leidthet tot hogere studenttevredenheid en betere prestaties bij de studen-ten die dit aangeboden krijgen t.o.v. wie dit niet krijgt aangeboden. Deprestaties en tevredenheid van studenten die practica van studentas-sistenten versus docenten zijn vergelijkbaar. Bij de organisatie van stu-dentassistenten in het onderwijs kan geleerd worden van de twee stro-mingen die nu prevaleren: Supplementele Instructie (si-pass ) enPeerAssistedLearning(pal ). Centrale coördinatie van het opleiden van bege-leiders en studentassistenten, duidelijke complementaire functieprofie-len, inzet bij praktische vakken, en inbedding binnen de opleidingen opbasis van passende leeruitkomsten kunnen bijdragen aan duurzame bor-ging.Students perform various types of educational tasks in higher education as teaching assistants. This systematic literature review mapped out the research on how teaching assistants are prepared for their tasks,what types of instruction they provide, and what this yields for both teaching assistants and students. The teaching assistants were primarily deployed in practical skills education and laboratory education in medical and chemistry programs, and to a lesser extent also in case-based education and metacognitive education. In terms of preparation, they benefited most from training that demonstrates expected behaviour, provides opportunities for practice, and offers feedback. The deployment of teaching assistants in education, as a supplement to regular instruction, resulted in higher student satisfaction and better performance. Regarding practical sessions, students taught by teaching assistants did not perform differently or express less satisfaction than those taught by teachers. In organizing student assistants in education, lessons can be learned from the two prevailing approaches: SI-PASS and PAL. Both central coordination with clear complementary job profiles for student assistants or integration within programs based on appropriate learning outcomes can contribute to sustainable implementation.
The aim of this research was to study the clinical characteristics and mortality and disability outcomes of patients who present distinct risk profiles for functional decline at admission. A multicenter, prospective cohort study was conducted between 2006 and 2009 in three hospitals in the Netherlands in consecutive patients of 65 years and over, acutely admitted and hospitalized for at least 48 hours. Nineteen geriatric conditions were assessed at hospital admission, and mortality and functional decline were assessed until twelve months after admission. Patients were divided into risk categories for functional decline (low, intermediate or high risk) according to the Identification of Seniors at Risk-Hospitalized Patients.
Mastering academic language (AL) by elementary school students is important for achieving school success. The extent to which teachers play a role in stimulating students’ AL development may differ. Two types of AL stimulating behavior are distinguished: aimed at students’ understanding and at triggering students’ production of AL. As mathematics requires abstract language use, AL occurs frequently. The instructional methods teachers use during mathematics instruction may offer different opportunities for AL stimulating behavior. In our first study, based on expert opinions, instructional methods were categorized according to opportunities they offer for stimulating students’ AL development. In the second study, video-observations of mathematics instruction of elementary school teachers were analyzed with respect to AL stimulating behavior and instructional methods used. Results showed that actual AL stimulating behavior of teachers corresponds to the expert opinions, except for behavior shown during task evaluation. Teachers differ in time and frequency of their use of instructional methods and therefore in opportunities for stimulating AL development. Four teaching profiles, reflecting different AL stimulating potential, were constructed: ‘teacher talking’, ‘balanced use of methods’, ‘getting students at work’ and ‘interactive teaching’. Teachers showed more types of behavior aimed at students’ AL understanding than at production.
