    I present my perspective on the design process in this article, arguing for a focus on student learning and "slow design" that stems from knowledge of mathematics and their support system in the learning process. I have a question about the design process academization and task design research direction. Numerous examples from my work at the Freudenthal Institute are used to illustrate this paper

    Mathematics Education and Neurosciences: Relating Spatial Structures to the Development of Spatial Sense and Number Sense

    Get PDF
    The Mathematics Education and Neurosciences (MENS) project is aimed at exploring the development of the mathematical abilities of young (four- to six-year old) children. It is initiated to integrate research from mathematics education with research from educational neuroscience in order to come to a better understanding of how the early skills of young children can best be fostered for supporting the development of mathematical abilities in an educational setting. This paper is specifically focused on the design research that is being conducted from the perspective of mathematics education in which we are investigating the relationship between young children’s insight into spatial structures and the development of spatial and number sense. This should result in a series of classroom activities that may stimulate children’s development of spatial and number skills

    This paper reports on the results of a four-year study called CASCADE-IMEI that is a learning environment (LE) in the form of a face-to-face course and a web site (www.clix.to/zulkardi ) which aims to introduce Realistic Mathematics Education (RME), Dutch approach to mathematics education, as an innovative teaching methods in Indonesia trough prospective mathematics teachers in initial teacher education. It also presents the background of mathematics reform in Indonesia by adapting RME as a promising approach. Then, the paper describes the process of a development research approach in which three prototypes of the LE have been developed and evaluated both by prospective mathematics teachers in Indonesian Educational University in Bandung and several experts in the Netherlands. Finally, it will discuss the changes on the prospective mathematics teachers after they followed the LE program with a more detailed on their teaching performance in junior secondary mathematics classroom

    Het CPT is een onafhankelijk comité ingesteld in het kader van de Raad van Europa, dat bevoegd is plaatsen te bezoeken waar personen van overheidswege van hun vrijheid beroofd worden vastgehouden. Naar aanleiding van zo’n inspectiebezoek rapporteert het CPT aan de betrokken lidstaat en doet het waar nodig aanbevelingen de geconstateerde detentiesituatie in dat land te verbeteren. Dit alles ter voorkoming van foltering en onmenselijke of vernederende behandeling of bestraffing. De centrale onderzoekvraag in deze dissertatie is wat de invloed is van het werk van het CPT voor de wijze waarop gedetineerden in Nederland worden vastgehouden

    Durability of treatment effects of the Sleep Position Trainer versus oral appliance therapy in positional OSA

    __Purpose:__ The Sleep Position Trainer (SPT) is a new option for treating patients with positional obstructive sleep apnea (POSA). This study investigated long-term efficacy, adherence, and quality of life during use of the SPT device compared with oral appliance therapy (OAT) in patients with POSA. __Methods:__ This prospective, multicenter trial randomized patients with mild to moderate POSA (apnea-hypopnea index [AHI] 5–30/h) to SPT or OAT. Polysomnography was performed at baseline and after 3 and 12 months’ follow-up. The primary endpoint was OSA severity; adherence, quality of life, and adverse events were also assessed. __Results:__ Ninety-nine patients were randomized and 58 completed the study (29 in each group). Median AHI in the SPT group decreased from 13.2/h at baseline to 7.1/h after 12 months; corresponding values in the OAT group were 13.4/h and 5.0/h, with no significant between-group difference. Improvements throughout the study were maintained at 12 months. Long-term median adherence was also similar in the two treatment groups; the proportion of patients who used their device for ≥ 4 h for 5 days in a week was 100% in the SPT group and 97.0% in the OAT group. __Conclusions:__ The efficacy of SPT therapy was maintained over 12 months and was comparable to that of OAT in patients with mild to moderate POSA. Adherence was relatively high, and similar in the two groups. Trial registration: _www.clinicaltrials.gov(NCT02045576).

    OBJECTIVE: To assess in-hospital and long-term mortality of Dutch ICU patients admitted with an acute intoxication. DESIGN: Cohort of ICU admissions from a national ICU registry linked to records from an insurance claims database. SETTING: Eighty-one ICUs (85% of all Dutch ICUs). PATIENTS: Seven thousand three hundred thirty-one admissions between January 1, 2008, and October 1, 2011. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Kaplan-Meier curves were used to compare the unadjusted mortality of the total intoxicated population and for specific intoxication subgroups based on the Acute Physiology and Chronic Health Evaluation IV reasons for admission: 1) alcohol(s), 2) analgesics, 3) antidepressants, 4) street drugs, 5) sedatives, 6) poisoning (carbon monoxide, arsenic, or cyanide), 7) other toxins, and 8) combinations. The case-mix adjusted mortality was assessed by the odds ratio adjusted for age, gender, severity of illness, intubation status, recurrent intoxication, and several comorbidities. The ICU mortality was 1.2%, and the in-hospital mortality was 2.1%. The mortality 1, 3, 6, 12, and 24 months after ICU admission was 2.8%, 4.1%, 5.2%, 6.5%, and 9.3%, respectively. Street drugs had the highest mortality 2 years after ICU admission (12.3%); a combination of different intoxications had the lowest (6.3%). The adjusted observed mortality showed that intoxications with street drugs and "other toxins" have a significant higher mortality 1 month after ICU admission (odds ratio adj = 1.63 and odds ratioadj= 1.73, respectively). Intoxications with alcohol or antidepressants have a significant lower mortality 1 month after ICU admission (odds ratioadj = 0.50 and odds ratioadj = 0.46, respectively). These differences were not found in the adjusted mortality 3 months upward of ICU admission. CONCLUSIONS: Overall, the mortality 2 years after ICU admission is relatively low compared with other ICU admissions. The first 3 months after ICU admission there is a difference in mortality between the subgroups, not thereafter. Still, the difference between the in-hospital mortality and the mortality after 2 years is substantial

    AbstractThis study attempts to explore the schemata or rhetorical patterns on reading comprehension of 300 state run university students of psychology and educational fields. The subjects involved were selected through stratified random sampling. This group includes two ways factorial design through random assignment. The variables of this article were investigated in three groups (100 subjects in each group). Each group was asked to recall the text and finish a multiple-choice test. The central instrument included three versions of passage with identical content but different schemata: descriptive (listing) pattern, explaining pattern and analysis pattern. Analysis of recall test indicated that subjects displayed better recall of the text with highly structured schema than the one with loosely controlled schema. The outcomes suggested that rhetorical patterns have a significant effect on written communication
