The research is created to investigate the prediction of admission criteria for medical student achievement in chemistry in Saudi Arabia. It examines if the General Aptitude Test (GAT), the Scholastic Achievement Admission Test (SAAT), and English competence, can to a certain extent predict and foretell students’ achievement in the chemistry. The study sample consists of 240 participants, providing their grades in the admission criteria and chemistry. Regression analyses are utilized to define the weight of individual admission criterion prediction for student achievement in chemistry. It illustrates that admission criteria could predict students’ grades in chemistry with a variance of 30%. The results also show English competence does play a more significant rule in predicting students’ performance in chemistry. More research is needed to examine whether these criteria are also predictors with a large scale of students’ population.

The following study tested the relationship between admission criteria and college students’ performance in an introductory physics course. For this study, I analyzed the performance of 250 students based on two college admission standardized tests (i.e., General Aptitude Test (GAT), Scholastic Achievement Admission Test (SAAT)), and English competence performance (i.e., average English course grades and reading and communication proficiency test). Based on this analysis, GAT and SAAT, along with English competence, are significant individual predictors for students’ performance in physics. Reading proficiency tests were the best individual predictors in simple linear regression analysis with 19.6% variance. The combined methods, with multivariate regression analysis, explained only 29.3% of physics course grade variance. This low variance of Saudi admission criteria for a single physics course should motivate Saudi policymakers to conduct a national study that includes an increased number of participants. Through such a national study, more evidence-based conclusions regarding the college admission system can be made to improve the admission process for Saudi students.

This study replicated an earlier study conducted by Tarter and Hoy (2004) in which an open systems model was used to test a series of hypotheses that explained elements of school performance. Four internal system elements (structure, individual, culture, and politics) of the school were used to explain two sets of school outcomes (student achievement and teachers’ assessment of overall school effectiveness) in a sample of 110 Catholic elementary schools in one Northeastern city. Correlational and multiple regression analyses were used to test the relationships. The results of this study further confirmed the usefulness of this model in understanding the factors that contribute to quality in elementary schools.

A 3-year demographic study was conducted to reveal targets of selection on morphology and life history in a population of Crepis tectorum ssp. pumila, a winter annual plant confined to calcareous grasslands (alvars) on the Baltic island of Öland (south Sweden). I calculated the selection differential to describe the change in the mean value of a character due to selection and used multiple regression analyses to partition the direct effect of selection on the trait from indirect responses of selection on other traits. Rosette leaf number, a convenient measure of plant size, was strongly correlated with both viability and fertility (fitness). There was also a strong relationship between fitness and the extent to which the plants expressed traits characterizing this particular taxon. Multiple regression analyses indicated direct selection favouring plants with deeply lobed leaves and a densely branched stem, two distinctive traits of ssp. pumila believed to be adaptive in the alvar habitat. Only stem height was subject to both direct and indirect selection in the wrong direction; taller individuals were more successful than those with a shorter stem, a surprising result considering the inferred advantage of a short stature in the exposed alvar habitat. Selection on other traits assumed to be ecologically important (germination time, flowering time, and seed size) was found to be either absent or variable in direction when other traits were held constant. The failure of plants to survive to the flowering stage in the last two summers indicates strong selection for plants that produce a high percentage of dormant seeds. Overall, the contemporary selection regime as revealed by demographic data was only partly congruent with predictions regarding historical selection pressures based on large-scale patterns of variation (ecotypic differentiation). Key words: Crepis tectorum, ecotypic differentiation, life history, morphology, phenotypic selection.

To support continuous professional development model in the teaching and learning of mathematics, many districts and schools have begun hiring elementary mathematics coaches and/or specialists (MCSs). However, limited large-scale empirical research exists that determines how the use of MCSs affect student learning and achievement. Kristin E. Harbour and Evthokia Stephanie Saclarides begin to fill in this gap by using data from the National Assessment of Educational Progress to explore the relationship between the presence and responsibilities of elementary MCSs and 4th-grade student achievement in mathematics. Based on their findings, they share practical implications for districts and administrators to consider.

Abstract Background Medical student mental health and wellbeing is highly topical worldwide. Research has tended to be either large-scale, quantitative, prevalence studies of wellbeing and associated factors such as burnout, or evaluations of single institution interventions. While theoretically informed definitions of wellbeing abound, how do medical students themselves understand and perceive wellbeing? What aspects of the curriculum do they regard as affecting their wellbeing and mental health? This study explored these questions, and aimed to identify factors associated with student acceptability of wellbeing programs and interventions. Methods All students at an Australian undergraduate medical school were invited to complete a qualitative online questionnaire between 2017 and 2018 following the introduction of several wellbeing initiatives, including “Wellbeing Days” (WBD). WBD allow students to take single absence days for self-care. Open-ended questions were asked about perceptions and experience of wellbeing and mental health, and views on interventions to improve wellbeing such as WBD. Thematic analysis was performed , initially by three authors who developed preliminary themes, then confirmed by all researchers . Thematic saturation was achieved within the 68 responses, which included participants from all cohorts. Results Participants described wellbeing as positively experienced work/life balance, impacted by four factors; contact hours, peer relationships, staff relationships, and trust in how wellbeing initiatives were used. Long course contact hours were deemed incompatible with self-care activities, maintaining employment, and seeking professional medical/psychological help. Peers could promote wellbeing by offering social and academic support, but also undermine wellbeing by being competitors. Degree of trust, engagement and communication with staff influenced acceptability of interventions. Participants viewed initiatives such as WBD favourably, but distrust of peers, and of staff, led to perceptions that WBD could be prone to misuse, or used for surveillance rather than support. Conclusion Our findings suggest that wellbeing days which allow self-care, reduction in contact hours, and peer support may promote student wellbeing, but the acceptability of any interventions is influenced by relationships between students and staff, and with peers. Further research is recommended to investigate the relationship between trust, perceptions of wellbeing in self and peers, and the effectiveness of wellbeing interventions.

Abstract Professional development is instrumental in the success of professionals and trainees in academic medicine. In response to medical student feedback requesting additional professional development opportunities, the Foster School of Medicine developed a distinction program, the Pathway for Preparing Academic Clinicians (PPAC), designed to deliver sought-after skill development and foundational knowledge in the three primary activities of academic medicine: medical education, research, and patient care. This distinction program addresses a curricular gap as identified by students and common to many UME curricula and also provides an opportunity for residency programs to identify student achievement within a pass/fail program.

International large-scale assessments of student achievement such as International Association for the Evaluation of Educational Achievement’s Trends in International Mathematics and Science Study (TIMSS) and Progress in International Reading Literacy Study and Organization for Economic Cooperation and Development’s Program for International Student Assessment that have come to prominence over the past 25 years owe a great deal in methodological terms to pioneering work by National Assessment of Educational Progress (NAEP). Using TIMSS as an example, this article describes how a number of core techniques, such as matrix sampling, student population sampling, item response theory scaling with population modeling, and resampling methods for variance estimation, have been adapted and implemented in an international context and are fundamental to the international assessment effort. In addition to the methodological contributions of NAEP, this article illustrates how the large-scale international assessments go beyond measuring student achievement by representing important aspects of community, home, school, and classroom contexts in ways that can be used to address issues of importance to researchers and policymakers.

Although there are many methods available for assessing text comprehension, the cloze test is not widely acknowledged as one of them. Critiques on cloze testing center on its supposedly limited ability to measure comprehension beyond the sentence. However, these critiques do not hold for all types of cloze tests; the particular configuration of a cloze determines its validity. We review various cloze configurations and discuss their strengths and weaknesses. We propose a new cloze procedure specifically designed to gauge text comprehension: the Hybrid Text Comprehension cloze (HyTeC-cloze). It employs a hybrid mechanical-rational deletion strategy and semantic scoring of answers. The procedure was tested in a large-scale study, involving 2926 Dutch secondary school students with 120 unique cloze tests. Our results show that, in terms of reliability and validity, the HyTeC-cloze matches and sometimes outperforms standardized tests of reading ability.

Daily and seasonal water temperature patterns were investigated at 22 habitats in five geomorphic reaches along an Alpine-Mediterranean river. Study reaches spanned 2nd- to 7th-order river segments. Habitats included headwater streams, main and secondary channels, backwaters, and isolated pools. Multiple linear regression analyses extracted elevation and azimuth (aspect) out of eight geographical and environmental variables to explain average daily temperature patterns among habitats. Azimuth and, to a lesser degree, slope, depth, velocity, and canopy were primary determinants of diel temperature amplitude and maximum rates of diel heating and cooling. Within lowland floodplain reaches, the relative influence of groundwater and surface water varied substantially among habitats. Thermal variation among habitats was greatest in lowland floodplain reaches (nearly 15°C difference). In summer and autumn, variation between lowland floodplain aquatic habitats exceeded thermal variation observed in the main channel along the entire river corridor (120 km; 5–1100 m above sea level). Spatiotemporal variation in temperature was greatest in lower reaches owing to the interaction of water level and connectivity of isolated water bodies. Influence of groundwater and cool-water tributaries exemplified the importance of local factors (geomorphology and hydrology) superimposed on regional factors (climate and altitude) in determining large-scale thermal patterns.
