This study assessed students' attitudes toward science in Qatar. A cross-sectional, nationwide probability sample representing all students enrolled grades 3 through 12 the various types of schools Qatar completed 'Arabic Speaking Students' Attitudes Science Survey' (ASSASS). The validity and reliability 32-item instrument, encompassing five sub-scales, have already been shown to be robust. present analysis focused on responses from 1978 participants who ASSASS Arabic. Descriptive statistics...

Science and mathematics teachers face the dual challenge of mastering subject-specific expertise developing pedagogical skills necessary for implementing integrated science, technology, engineering, (STEM) lessons. Research indicates a deficiency in teachers’ competencies, particularly project-based learning (PBL) within STEM context. To address this, study administered questionnaire to 245 specialized science Qatar, aiming examine their competencies self-efficacy realm technological content...

Since early 2020, nurses have been fighting on the frontlines to save people's lives during COVID-19 pandemic, which has thrown and other healthcare professionals into public eye like never before. So, exploring their information needs battle will help identify improve preparedness when drawing up crisis plans. Thus, this paper investigates of how they met those needs, problems encountered in seeking information. A questionnaire was used collect data from 386 52 Egyptian hospitals; 44%...

Background:Science education reform in Qatar has had limited success. In the Trends International Mathematics and Science Study (TIMMS), Qatari 4th 8th grade students have shown progress science achievement, but they remain significantly below international average. Also, Program for Student Assessment (PISA), are again average.Material methods:data were analyzed from tests of TIMMS (2007 2011) PISA (2006, 2009, 2012). addition, data collected a total 92 coordinators teachers 24 schools by...

This study is part of a large-scale project focused on 'Qatari students' Interest in, and Attitudes toward, Science' (QIAS). QIAS aimed to gauge Qatari student attitudes toward science in grades 3–12, examine factors that impact these attitudes, assess the relationship between prevailing modes teaching schools. report details development validation 'Arabic-Speaking Students' Science Survey' (ASSASS), which was specifically developed for purposes project. The theories reasoned action planned...

In Qatar's gender-segregated public schools, female students outperform male in international science tests such as PISA and TIMMS. contrast to the trend for top performing countries, however, report lower levels of interest science-based careers than males. One possible factor that may contribute this discrepancy is difference teaching styles between teachers their counterparts. paper we focus on results obtained from 105 classroom observations (39 males 66 females) selected 50 different...

This paper is part of a project on enhancing STEM teaching through teachers’ professional development (TPD). The aim to explore K-12 science and mathematics views practices about implementing technological pedagogical content knowledge (TPACK) model in Qatar identify their challenges. objective develop TPD program using project-based learning intervention support teachers train them how implement PBL practices. 245 from 16 preparatory secondary schools, representing an equal number males...

This study aimed to explore how secondary school science and mathematics teachers in Qatar integrate Technological Pedagogical Content Knowledge (TPACK) into their teaching practices. The examined the relationships between subcomponents of TPACK using structural equation modeling (SEM), complemented by an analysis additional categorical variables. A total 245 from participated research. model’s findings showed that internal components—technological knowledge, pedagogical content...

A large sample (n = 1,799) of Qatari female and male students at the preparatory, secondary, university levels responded to Likert items about their interest, attitude, self-efficacy regarding science. The were similar those TIMSS PISA, but improved upon them in several ways. findings suggest that are positive self-efficacy, not as PISA report. raise an important question: If students' positive, then why do have relatively low achievement scores on PISA? answer may be instructional methods...

This paper uncovers the sustainability content in science and mathematics curriculum of Qatar's K-12 public school system. It focuses on mapping standards both subjects against sustainable development goals (SDGs) identifying existing gap. The mapping, using a key-words approach, concepts based UN UNESCO documents, with found that among 410 science, total 53 are addressed, to some extent, by SDGs-related contents, i.e. 12.7%. major addressed SDGs descending order SDG13 climate change; SDG15,...

Abstract In both thermal emulsion polymerization of styrene in the temperature range 60–80 °C, and peroxodisulfate‐initiated at 60 weight‐average to number‐average molecular‐weight ratios ( M̄ w / n ) approach 1,5 when potassium octadecanoate is used as emulsifier. A low activation energy for initiation (≈66,0 kJ/mol) was deduced which may indicate a catalytic effect emulsifier during process. Participation probably attributed transfer one two monomer radicals, produced thermally,...

ABSTRACT Procion Red MX-3B-attached poly(ethylene glycol dimethacrylate-hydroxy-ethyl methacrylate [poly(EGDMA-HEMA)] microbeads were prepared for removal of Cu2+ ions from aqueous media containing different amounts (2–50 ppm). characterized by FTIR, optical microscopy and elemental analysis. Dye-attached with a swelling ratio 55% carrying 8.95 μmol MX-3B/g polymer used in the adsorption-desorption ions. Very high adsorption rates observed at beginning process then equilibrium was achieved...

It has been recognized for many years that the topic of energy is an avenue provides students with engaging opportunities to experience how science actually done. As a topic, cuts across disciplines and also develop series practices or skills works. Inquiry certainly more than hands‐on in part state mind – inquisitiveness. How do we create educational system exploits natural curiosity children? This paper will discuss initiation three‐year, multifaceted project Qatar seeks strengthen...

Abstract The effects of adding potassium chloride in concentrations below that required to coagulate the latex recips emulsion polymerisation styrene have been investigated using different octadecanoate, which has a low critical micelle concentration (CMC), and dodecanoate, moderately high CMC. At relatively octadecanoate final particle size is significantly increased; rate initially increased but later retarded. increasing coalescence are dominant. lower this emulsifier, reduced from onset...

There has been a serious decline over the last 15 years in number of students studying mathematics and science at both secondary tertiary levels education Qatar. This paper explores major factors influencing student attitudes towards science, as well interest enrollment subjects, by addressing following question: What are Qatari precollege students’ in, toward, grades 3 through 12? Answers to this research question relied on data from comprehensive pilot study involving 60 Likert scale...

The effects of adding inorganic electrolyte (below the critical coagulation concentration) have been investigated in two systems for emulsion polymerisation styrene. In one system, potassium chloride, at different concentrations, was added end interval I, using three ionic emulsifiers: octadecanoate which has a low micelle concentration (CMC), dodecanoate and sodium dodecyl sulphate (SDS), moderately high CMC. A significant increase rate observed all cases even higher levels is reduced if...
