Development of Activity-Based Science Learning Models with Inquiry Approaches

This study aims to develop an activity-based science learning model with an inquiry learning approach for early childhood that can be used to increase the sense of curiosity and sci-entific thinking in children aged 5-6 years. This study was conducted with research and de-velopment / R & D research methods. Data was collected through interviews, observations, questionnaires, pre-test and post-test for children. Data analysis using paired t-test. The re-sults showed that children were interested and enthusiastic in the learning process by using a science-based learning model with the inquiry approach, Sig. (2-tailed) showing results of 0.000, so the value of 0.000 <0.05 was different from before and after the use of learning models . Results show children can understand the material, more confident and has initiative to find answers for the teacher's questions about science, the child's curiosity increases to ex-amine the information provided by the teacher, the child's understanding of work processes and procedures from science learning with the inquiry approach getting bet-ter. It was con-cluded that an activity-based science learning model with an inquiry approach for children aged 5-6 years used an activity model with an inquiry learning approach based on children's interests and children's needs so that children's curiosity would emerge and continue to be optimally stimulated.

Phacoemulsification with posterior chamber intraocular lens versus extracapsular cataract extraction (ECCE) with posterior chamber intraocular lens for age-related cataract.

BACKGROUND: Age-related cataract is one of the leading causes of blindness worldwide. Therefore, it is important to establish the most effective surgical technique for cataract surgery. OBJECTIVES: The aim of this review is to examine the effects of two types of cataract surgery for age-related cataract: phacoemulsification and extracapsular cataract extraction (ECCE). SEARCH METHODS: We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2013, Issue 4), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to May 2013), EMBASE (January 1980 to May 2013), Latin American and Caribbean Literature on Health Sciences (LILACS) (January 1982 to May 2013), Web of Science Conference Proceedings Citation Index - Science (CPCI-S) (January 1970 to May 2013), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 13 May 2013. SELECTION CRITERIA: We included randomised controlled trials of phacoemulsification compared to ECCE for age-related cataract. DATA COLLECTION AND ANALYSIS: Two authors independently selected and assessed all studies. We defined two primary outcomes: 'good functional vision' (presenting visual acuity of 6/12 or better) and 'poor visual outcome' (best corrected visual acuity of less than 6/60) at three and 12 months after surgery. We also collected data on intra and postoperative complications, and the cost of the procedures. MAIN RESULTS: We included 11 trials in this review with a total of 1228 participants, ranging from age 45 to 94. The studies were generally at unclear risk of bias due to poorly reported trial methods. No study reported presenting visual acuity, so we report both uncorrected (UCVA) and best corrected visual acuity (BCVA). Studies varied in visual acuity assessment methods and time frames at which outcomes were reported. Participants in the phacoemulsification group were more likely to achieve UCVA of 6/12 or more at three months (risk ratio (RR) 1.81, 95% confidence interval (CI) 1.36 to 2.41, two studies, 492 participants) and one year (RR 1.99, 95% CI 1.45 to 2.73, one study, 439 participants). People in the phacoemulsification group were also more likely to achieve BCVA of 6/12 or more at three months (RR 1.12, 95% CI 1.03 to 1.22, four studies, 645 participants) and one year (RR 1.06, 95% CI 0.99 to 1.14, one study, 439 participants), but the difference between the two groups was smaller. No trials reported BCVA less than 6/60 but three trials reported BCVA worse than 6/9 and 6/18: there were fewer events of this outcome in the phacoemulsification group than the ECCE group at both the three-month (RR 0.33, 95% CI 0.20 to 0.55, three studies, 604 participants) and 12-month time points (RR 0.62, 95% CI 0.36 to 1.05, one study, 439 participants). Three trials reported posterior capsule rupture: this occurred more commonly in the ECCE group than the phacoemulsification group but small numbers of events mean the true effect is uncertain (Peto odds ratio (OR) 0.56, 95% CI 0.26 to 1.22, three studies, 688 participants). Iris prolapse, cystoid macular oedema and posterior capsular opacification were also higher in the ECCE group than the phacoemulsification group. Phacoemulsification surgical costs were higher than ECCE in two studies. A third study reported similar costs for phacoemulsification and ECCE up to six weeks postoperatively, but following this time point ECCE incurred additional costs due to additional visits, spectacles and laser treatment to achieve a similar outcome. AUTHORS' CONCLUSIONS: Removing cataract by phacoemulsification may result in a better visual acuity compared to ECCE, with a lower complication rate. The review is currently underpowered to detect differences for rarer outcomes, including poor visual outcome. The lower cost of ECCE may justify its use in a patient population where high-volume surgery is a priority, however, there are a lack of data comparing phacoemulsification and ECCE in lower-income settings

Capturing cultural differences between UK and Malaysian drivers to inform the design of in-vehicle navigation systems

Attending to cultural diversity is important for products and technology intended for global placement, such as automobiles, yet many products (and associated interfaces) lack genuine cultural differentiation. For example, in-vehicle navigation systems are typically identical in form and function across world markets, differing only in the local language and map database. To capture and explore culturally-salient design factors, we utilised a scenario-based design methodology, involving 6 experienced drivers from the UK and Malaysia. Participants were asked to portray their ideal navigation system interface designs – by drawing pictograms and devising accompanying spoken messages – to direct drivers along 3 prescribed routes in the UK, Malaysia and Japan. Routes were presented using video and paper maps, with the order of presentation counterbalanced between groups; participants were not told in advance from which country each route was derived. Proposed designs highlight differences at a country level, which are consequently interpreted from a cultural perspective. For example, Malaysian drivers included a higher density of navigational elements in their designs, particularly in their home environment, compared to UK drivers. Malaysian drivers also created more incremental designs, particularly on the approach to a manoeuvre, suggesting a desire for greater navigational support at this point in the journey. Landmarks were consistently incorporated in designs, but differences were noted in cultural salience. Additionally, the phrasing of instructions (e.g. “go straight on”), nomenclature for road elements (e.g. ‘roundabout’) and distance declaration conventions (e.g. units) differed at a country level. The findings can be used to inform the design of culturally-attuned in-vehicle navigation systems

Capturing Children’s Mathematical Knowledge: An Assessment Framework

This paper explores an innovative assessment framework for measuring children’s formal and informal mathematical knowledge. Many existing standardized measures, such as the Early Grade Mathematics Assessment, measure children’s performance in early primary grade skills that have been identified by researchers and policy makers as foundational and predictive of later academic achievement (Platas, Ketterlin-Geller, & Sitabkhan, 2016; RTI International, 2014). However, these standardized assessments only provide information on children’s mathematical ability as it pertains to skills and concepts that are a focus of school instruction, referred to as formal mathematics. While valuable, they leave unmeasured the mathematics that children use and develop as part of their everyday life, such as the strategies they use to solve simple arithmetical problems that arise as they move through their day (Khan, 1999; Saxe, 1991; Taylor, 2009).  In this article, we draw from mixed methods studies which focus on capturing the informal mathematical skills that children develop outside of school in various contexts (Guberman, 1996; Nasir, 2000; Sitabkhan, 2009; Sitabkhan, 2015). We describe how the use of observations of children’s mathematical activities in natural settings and subsequent cognitive interviews using mathematical tasks derived from those observations can illuminate mathematical knowledge and skills that may otherwise remain hidden. We found that an assessment framework that focuses on both standardized measures of formal mathematical learning and contextualized measures of children’s everyday mathematics can provide a more complete and nuanced picture of children’s knowledge, and taken together can inform the development of curricular materials and teacher training focused on early learning

The parent play questionnaire: development of a parent questionnaire to assess parent–child play and digital media use

We introduce the Parent Play Questionnaire (PPQ), a parent-report measure designed to assess frequency of parent–infant play, parents’ attitudes towards play with their infant, and infants’ use of digital media. We describe measure development and empirical data across three samples of parent–infant dyads (total N = 414, offspring aged 0.3–2.5 years). Three latent factors explain the PPQ, corresponding with theoretically defined subscales. Summary scores showed good internal consistency and normally distributed results. Weak to moderate correlations were found between the frequency and attitude play scales, and with standardized measures of family social and emotional characteristics. Overall, frequency of digital media use was not correlated with play or broader family variables. Results suggest that the PPQ will be a useful tool for researchers interested in assessing parent–child play during early childhood

How do intrahousehold dynamics change when assets are transferred to women? Evidence from BRAC’s challenging the frontiers of poverty reduction—targeting the ultra poor program in Bangladesh

Growing evidence shows that the distribution of individuals' ownership and control of assets within a household can have important implications for women’s empowerment and children’s well-being. Interventions that target assets to specific individuals can shift these intrahousehold dynamics, yet little evidence exists from rigorous evaluations. We study BRAC’s Challenging the Frontiers of Poverty Reduction—Targeting the Ultra Poor (CFPR-TUP) program in Bangladesh, which targets asset transfer (primarily livestock) and training to rural women in poor households. Previous research has shown large, significant positive program impacts at the household level. In this paper, we examine intrahousehold impacts using mixed methods. We focus on the Specially Targeted Ultra-Poor(STUP) component of the program, which targets households selected following a randomized controlled trial design. Adding a new round of data collection with quantitative sex-disaggregated information and qualitative exploration, we exploit the randomized design to assess intrahousehold impacts of STUP. Our analysis confirms that the program significantly increases household ownership of various assets but has complex effects on the targeted women. Quantitative estimates show increases in women’s sole and joint ownership of or control over transferred assets such as livestock, but a much greater increase in men’s sole ownership over nearly all other assets (including agricultural and nonagricultural productive assets, land, and consumer durables). These findings suggest that while the transferred assets tend to remain with women, new investments from mobilized resources are controlled by men. Moreover, the program reduces women’s mobility outside the home and their control over income, consistent with the transferred asset’s requiring maintenance at home. Qualitative findings are consistent with these quantitative results , but women’s contribution to their households is perceived as increasing their confidence and social capital, which they themselves value. Therefore, while provision of assets and training to women has ambiguous effects on women’s empowerment in terms of tangible assets and decisionmaking, women take intangibles into account and largely perceive positive (though still mixed) effects. The analysis shows that asset transfer targeted to women can increase women’s ownership of and control over the transferred asset itself but may not necessarily increase women’s intrahousehold bargaining position. Moreover, it reveals that outcomes valued by individuals may not always be tangible, highlighting the complexity of assessing whether interventions improve women’s empowerment
