We present an inquiry-based, hands-on laboratory exercise on enzyme activity for an introductory college biology course for science majors. We measure student performance on a series of objective and subjective questions before and after completion of this exercise; we also measure performance of a similar cohort of students before and after completion of an existing, standard, “direct” exercise over the same topics. Although student performance on these questions increased significantly after completion of the inquiry exercise, it did not increase after completion of the control, standard exercise. Pressure to “cover” many complex topics as preparation for high-stakes examinations such as the Medical College Admissions Test may account for persistence of highly efficient, yet dubiously effective “cookbook” laboratory exercises in many science classes.

Attrition from medical school remains a serious cause of concern for the medical education community. Thus, there is a need to improve our ability to select only those candidates who will succeed at medical school from many highly qualified and motivated applicants. This can be achieved, in part, by reducing the reliance on cognitive factors and increasing the use of noncognitive character traits in high-stakes admissions decisions. Herein we describe an analytic rubric that combines research-derived predictors of medical school success to generate a composite score for use in admissions decisions. The analytic rubric as described herein represents a significant step toward evidenced-based admissions that will facilitate a more consistent and transparent qualitative evaluation of medical school applicants beyond their grades and Medical College Admissions Test scores and contribute to a redesigned and improved admissions process.

Most American colleges and universities offer gateway biology courses to meet the needs of three undergraduate audiences: biology and related science majors, many of whom will become biomedical researchers; premedical students meeting medical school requirements and preparing for the Medical College Admissions Test (MCAT); and students completing general education (GE) graduation requirements. Biology textbooks for these three audiences present a topic scope and sequence that correlates with the topic scope and importance ratings of the biology content specifications for the MCAT regardless of the intended audience. Texts for “nonmajors,” GE courses appear derived directly from their publisher's majors text. Topic scope and sequence of GE texts reflect those of “their” majors text and, indirectly, the MCAT. MCAT term density of GE texts equals or exceeds that of their corresponding majors text. Most American universities require a GE curriculum to promote a core level of academic understanding among their graduates. This includes civic scientific literacy, recognized as an essential competence for the development of public policies in an increasingly scientific and technological world. Deriving GE biology and related science texts from majors texts designed to meet very different learning objectives may defeat the scientific literacy goals of most schools’ GE curricula.

The No Child Left Behind Act (NCLB) has been criticized for encouraging schools to neglect students whose performance exceeds the proficiency threshold or lies so far below it that there is no reasonable prospect of closing the gap during the current year. We examine this hypothesis using longitudinal data from 2002–03 through 2005–06. Our identification strategy relies on the fact that as NCLB was phased in, states had some latitude in designating which grades were to count for purposes of a school making adequate yearly progress. We compare the mathematics achievement distribution in a grade before and after it became a high-stakes grade. We find in general no evidence that gains were concentrated on students near the proficiency standard at the expense of students scoring much lower, though there are inconsistent signs of a trade-off with students at the upper end of the distribution.

Background: Iron deficiency anaemia (IDA) is the most common nutritional deficiency in pregnancy and major contributory factor to maternal morbidity and mortality. Objective of present study was to assess knowledge of pregnant women regarding anaemia and its preventive measures before and after educational interventional training.Methods: The present study was an interventional study undertaken in purposively selected pregnant women attending the out patient Department of Obstetrics and Gynecology Department of GMERS Medical College, Gandhinagar During the month of October 2017. Total 100 pregnant women were included after written informed consent. Baseline knowledge of pregnant women regarding anaemia and its preventive measures was assessed by pre-designed, pre-tested and semi structured questionnaire. Single educational interventional training for 45 minutes was given to selected pregnant women. Post– intervention knowledge of pregnant women for the same was assessed after training. Thus, collected data was analyzed /using Epi info 7.Results: Baseline knowledge of the pregnant women regarding causes, signs and symptoms of anemia and dietary sources of iron was 21%, 23% and 40% respectively which was significantly increased to 64%, 66% and 72% respectively after the intervention. Baseline knowledge of the pregnant women regarding factors which inhibit and increase iron absorption was 25% and 4% respectively which was significantly increased to 55% and 41 % respectively after the intervention. Baseline knowledge of the pregnant women regarding treatment of anaemia was 30% which was significantly increased to 79 % after the intervention.Conclusions: There was significant improvement in the knowledge regarding anaemia and its preventive measures among pregnant women after our single educational session.

Texas provides a unique opportunity to examine teachers without standard university preparation, for it prepares more teachers through alternative pathways than any other state. We find two advantages for mathematics and science teachers prepared in the standard way. First, since 2008 they have been staying in the classroom longer than those who pursued alternative routes. Second, we analyze student performance on Algebra 1 and Biology exams over the period 2012-2018. Algebra I students with experienced teachers from standard programs gain .03 to .05 in standard deviation units compared to students whose teachers were alternatively prepared. For Biology students there are fewer statistically significant differences, although when differences exist they almost all favor standard programs. These effects are difficult to measure in part because teachers are not assigned to teach courses with high-stakes exams at random. Nevertheless, we find strong evidence in Algebra I that students learn more when their teachers have standard preparation. In Biology there is also evidence but less compelling. Thus, we recommend that all states bolster traditional university-based teacher certification, that Texas not take drastic action to curtail alternative certification, and that other states not allow it to grow too quickly.

Background: Many students enter into postsecondary education without the college readiness skills that allow them to face the demands of postsecondary education. Increasingly, policymakers and educational researchers are responding to calls for reforming secondary education to provide more opportunity for all students to receive high quality education and to become career and college ready. Purpose: This study attempts to identify levers to increase student performance in secondary education. In particular, it examines relationships of school, teaching, teacher, and teacher professional development characteristics with student scores on high-stakes Advanced Placement (AP) examinations in the sciences.Setting: This study is situated in the context of the large-scale, top-down, nationwide AP curriculum and examination reform in the sciences (Biology, Chemistry, Physics) in the United States. This is an unprecedented opportunity to analyze changing educational landscapes in the United States with large-scale national student-, teacher-, school-, and district-level data sets across multiple science disciplines and different stages of the curriculum reform implementation connected to a standardized and high-stakes student outcome measure.Population: This study analyzes nationwide data samples of the AP Biology, AP Chemistry, and AP Physics population during the first, second, and third year of the curriculum reform implementation. Across disciplines and years, the analytical samples include a total of 113,603 students and 6,046 teachers. Research design: This empirical quantitative study uses data from web-based surveys sent to all AP science teachers. Additionally, College Board provided student- and school-level data for all students taking AP examinations. Data preparation methods included exploratory and confirmatory factor analysis. Associations towards student achievement were analyzed through multi-level ordered logistic regression analysis separately by science discipline and year of the curriculum reform implementation. Afterwards, the results were aggregated through a meta-analysis. Findings: Student performance is not pre-determined by students’ background, leaving roughly 60% of the AP score variance potentially malleable for teacher and school-level factors. In particular, teachers’ perceived administrative support, self-efficacy, teaching experience, and elements of classroom instruction were related to student performance. Notably, teachers’ professional development participation has a small, mixed impact on student achievement. Conclusion: The identified levers for improving student achievement provide a strong rationale for the continued efforts of policy makers to improve school environments and to support science teachers to ultimately both increase student learning and help all students graduate prepared for college and ready for their future careers.

This paper presents a retrospective evaluation of the Higher Colleges of Technology’s student assessments during the COVID-19 lockdown, reflecting the justified decision to deploy graded assessments during the lockdown for students to academically progress and/or graduate on time, while maintaining the quality and rigor of academic awards. The outcome-based evaluation of this paper is intended to provide lessons for any future situations of this significance and magnitude. While online education was the obvious response to the pandemic, the provision of assessments was not possible without risk. Taking a high-stakes decision that would affect the future of thousands of students, for years to come, involved complex steps of reasoning and justification. Addressing the role of graded assessment in supporting institutional accountability and transferability of students’ achievements, student efficacy and informed pedagogy alterations were the main objectives. To meet those objectives, the Higher Colleges of Technology was able to deploy an off-campus student assessment model that builds upon three pillars of adjustments (assessment development and deployment; technology infrastructure; and governance resilience) to support students’ learning, while mitigating vulnerabilities. The evaluation of student performance indicators and stakeholders’ satisfaction rates revealed a successful deployment of off-campus assessment while maintaining the traditional conventions pertaining to evaluation of assessments.
