A comparison of cognitive skills between completes and dropouts in a college physics course

Separate tests of mathematics skills, proportions and translations between words, and mathematical expression given the first week of class were correlated with performance for students who completed a college physics course (completes) and students who dropped the course (drops). None of the measures used discriminated between completes and drops as groups. However, the correlations between score on the test of math skills and on both of the measures involving mathematical reasoning (proportions, and translations) were dramatically different for the two groups. For the completes, these correlations were slightly negative, but not significant. For the drops, the correlation was positive and signficant at the p < 0.01 level. This suggests the possibility that the students who complete the course tend to have independent cognitive skills for the “mechanical” mathematical operations and for questions requiring some degree of reasoning, while, in contrast, the same skills for students at high risk for dropping overlap significantly. The study also found that when students are given the results of mathematics skills tests in a diagnostic mode, with feedback on specific areas of weakness and time to remediate with self study, the correlation between mathematics and physics is lower than previously reported values.     

Improving Academic Performance of Sport and Exercise Science Undergraduate Students in Gross Anatomy Using a Near-Peer Teaching Program

Peer and near-peer teaching programs are common in medical undergraduate courses. However, there are no studies that have investigated the effectiveness of a near-peer teaching program on the academic performance of undergraduate students pursuing sport and exercise science coursework. This study was conducted to analyze the effectiveness of such a program for students who participated in a course on the functional anatomy of the locomotor apparatus. A total of 39 student participants were divided into two groups: students in one group voluntarily attended at least one session of a near-peer teaching program, and students in the other group attended no sessions. The final grade (range 0–100%) was recorded and used as an indicator of academic performance. The final grade of students who attended the near-peer teaching program (69.5 ± 16.0%) was 38.7% higher (P = 0.002, d = 1.06) than those who did not (50.1 ± 20.4%). When the academic performance of the same students was evaluated in another course (exercise physiology) that did not offer a near-peer teaching program, there were no significant differences between the groups (students who attended or did not attend the near-peer teaching program). A significant positive association was found between near-peer teaching program frequency and the number of students approved and not approved in the course (P = 0.041). A significant difference (P = 0.001) was found in the attendance at regular classes between the group who participated in the near-peer teaching program (median: 62 hours; IQR [interquartile ranges]: 4.0 hours) and those who did not (median: 58 hours; IQR: 4.0 hours). Gender was not a moderating factor on academic performance or near-peer teaching program attendance. These results highlight the effectiveness of a near-peer teaching program on the academic performance of students from a sport and exercise science degree program while enrolled in an anatomy course.

Relative success in college chemistry for students who experienced a high-school course in chemistry and those who had not

A total of 53 high-ability students who had completed the eleventh year in high school enrolled in a standard college chemistry course at the University of Iowa. Half of them had completed a high-school course in chemistry and half had not. After 2 months of instruction during a summer session, there was no difference between groups as to attitude toward chemistry, performance on the ACS-NSTA Chemistry Achievement Examination, final examination for the course, and course grade. There was a great difference in the amount of time required of tutors; the students who had not completed high-school chemistry spent more time in studying and with tutors.     

Success of students in a college physics course with and without experiencing a high school course

High school students with high ability were enrolled in a standard college physics course for each of two summers with the same professor, same course outline, same textbook, same laboratories, and the same examinations. Half of each group had completed a high school physics course; half had not. Dormitory counselors were available for assistance and support. In addition, tutors were available in the laboratories to provide any help necessary with interpretation of lectures and performances in the laboratory, and with mathematical computation. Pre- and posttest measures concerning course content and attitude were given. After the eight-week summer instruction, the students who had not completed high school physics performed as well on the final course examination; there were no differences with respect to course grade or attitude toward physics. The group that had not completed high school physics used the tutors provided far more frequently than did students who had completed the high school course. When high-ability students are enrolled in college physics with tutors made available for needed assistance, there appears to be no advantage for students to complete the standard high school physics course.     

Minimal Impact of Organic Chemistry Prerequisite on Student Performance in Introductory Biochemistry

Curriculum design assumes that successful completion of prerequisite courses will have a positive impact on student performance in courses that require the prerequisite. We recently had the opportunity to test this assumption concerning the relationship between completion of the organic chemistry prerequisite and performance in introductory biochemistry. We found no statistically significant differences between average biochemistry grades or grade distribution among students with or without the organic chemistry prerequisite. However, students who had not completed the organic chemistry prerequisite before biochemistry were more likely to withdraw from the course than those who had completed the prerequisite. In contrast to the lack of correlation between performance in biochemistry and completion of organic chemistry, we observed a strong, highly significant positive relationship between cumulative GPA and the biochemistry grade. Our data suggest that excluding students without organic chemistry would have less positive impact on student success in biochemistry than would providing additional support for all students who enroll in biochemistry with a cumulative GPA below 2.5.     

Academic Factors Related to Student Achievement in a Capstone Food Chemistry Course

The 1st step in successfully intervening with students who may fail a course is to identify them as early as possible in the semester. The objective of this study was to create a model to predict student performance in FDSC 4304, the required capstone Food Chemistry class, using academic performance in prerequisite courses as potential predictors. We analyzed data for 116 undergraduates who completed Food Chemistry (FDSC 4304) between 2008 and 2015. Data included semester of enrollment and grade earned in FDSC 4304; transfer status; grades in prerequisite classes in science, math, and statistics courses and an introductory Food Science course, FDSC 1103; and the students’ university GPA at the time of enrollment in FDSC 4304. Cumulative GPA had the strongest significant (P < 0.001) positive correlation with FDSC 4304 grade (r = 0.64), followed by grade in statistics GPA (r = 0.52), FDSC 1103 grade (r = 0.45), pre‐requisite chemistry GPA (r = 0.44), and biology GPA (r = 0.42). When using partial correlations to control for cumulative GPA, only grades in FDSC 1103 (completed by 62.9% of students) were significantly correlated with grades in FDSC 4304. Linear regression indicated cumulative GPA and FDSC 1103 grades explained 35.5% of the variance in FDSC 4304 grades. When cumulative GPA (available for 91.6% of students) alone was regressed on FDSC 4304, it explained 40.6% of the variance for the larger group. Lower cumulative GPAs and FDSC 1103 grades are suggestive but not determinative of potential student struggles in FDSC 4304. Instructors should use cumulative GPAs and introductory food science course grades (either alone or in combination) with actual early course performance measures to identify students in need of additional help.     

Performance in a prematriculation gross anatomy course as a predictor of performance in medical school

The University of California at Davis School of Medicine offers a prematriculation program to nontraditional students. As part of the program, students take a 7‐day course on the gross anatomy of the upper limb that concludes with a written examination and a practical examination based on prosections. Here, the performance of students who took the course from 2002 to 2004 (n = 48) is compared with their performance in the medical gross anatomy course as well as their performance on Step 1 of the United States Medical Licensing Examination (USMLE). Both rank in the prematriculation program's anatomy course and the score on the examination were correlated (significant at the 0.01 level) with performance on the medical gross anatomy midterm and final examinations, the overall final grade, and class rank. Performance in the prematriculation anatomy course was also correlated with the score on Step 1 of the USMLE (rank significant at the 0.02 level; examination score, significant at the 0.05 level). Students who took the prematriculation course who eventually withdrew, were dismissed for academic reasons, or who failed the first attempt at the Step 1 of the licensing exam (n = 5) had a significantly lower score (77.6 ± 11.1; P < 0.05) on the prematriculation examination than did successful prematriculation students (86.2 ± 7.9). Thus, a gross anatomy examination following a short prematriculation course can be a predictor not only of medical student performance in anatomy, but also of performance on a standardized licensing examination.

Lecture recording system in anatomy

The literature reports that using Learning Recording Systems (LRS) is usually well received by students but that the pedagogical value of LRS in academic settings remains somewhat unclear. The primary aim of the current study is to document students' perceptions, actual pattern of usage, and impact of use of LRS on students' grade in a dental gross and neuroanatomy course. Other aims are to determine if students' learning preference correlated with final grades and to see if other factors like gender, age, overall academic score on the Dental Aptitude Test (DAT), lecture levels of difficulty, type of lecture, category of lecture, or teaching faculty could explain the impact, if any, of the use of LRS on the course final grade. No significant correlation was detected between the final grades and the variables studied except for a significant but modest correlation between final grades and the number of times the students accessed the lecture recordings (r=0.33 with P=0.01). Also, after adjusting for gender, age, learning style, and academic DAT, a significant interaction between auditory and average usage time was found for final grade (P=0.03). Students who classified themselves as auditory and who used the LRS on average for fewer than 10 minutes per access, scored an average final grade of 16.43 % higher than the nonauditory students using the LRS for the same amount of time per access. Based on these findings, implications for teaching are discussed and recommendations for use of LRS are proposed. Anat Sci Educ 6: 376–384. © 2013 American Association of Anatomists.     

Resilience does not predict academic performance in gross anatomy

Few studies have evaluated resilience in an academic environment as it relates to academic success or failure. This work sought to assess resilience in regular and remedial students of gross anatomy during the first and second semesters of medical school and to correlate this personal trait with academic performance. Two groups of students were compared: the first group included first‐year medical students in the regular course, and the second group included first‐year medical students who did not pass the regular anatomy course and so were enrolled in the remedial course. Both groups completed anonymous surveys designed to gather demographic data and establish scores on the Connor‐Davidson resilience scale, which includes 25 statements rated zero to four on a Likert scale (maximum score 100). The average resilience score was the same for both groups, 80 ± 9. The average anatomy grades differed significantly between regular students (67± 15.0) and remedial students (61 ± 12.0). While there was no overall correlation between resilience score and anatomy grade, regular students with resilience scores of 75 or greater showed slightly better academic performance than their classmates. Similarly, remedial students with resilience scores of 87 or greater faired better academically. Resilience does not predict academic performance in gross anatomy, and further work is necessary to identify those intrinsic and extrinsic factors that influence students' achievements.

Klassenwiederholen in PISA-I-Plus: Was lernen Sitzenbleiber in Mathematik dazu?

This study analyses the effects which repeating a class has on ninth grade students’ development of mathematical competency. The following research questions were addressed: How many students repeat grades in the different types of schools? How do students who repeat a grade differ from those who do not in their performance and background characteristics? How much extra mathematics do students repeating a grade learn in one school year? What are the differences between various types of school? Can students with poor mathematics grades in particular profit from repeating a grade? The sample is a sub-sample of the PISA-I-Plus study and comprises N = 360 ninth grade students. The total sample of PISA-I-Plus is representative for all ninth/tenth grade students from the different school types in Germany. The data survey was carried out in the ninth grade and then repeated after the students had repeated a year. The results document differences in the amount of grade repeat quotas between types of school. Furthermore, compared to students not repeating, those repeating a grade had lower mathematics (d = 1.02) and german (d = 1.14) grades, a lower level of mathematical literacy (d = 0.51), and lower test results with regard to basic cognitive abilities (d = 0.32). In terms of the development of mathematical literacy, the students repeating a grade could improve by an average of 23 points (d = 0.27) on the PISA mathematics scale. However, the results identify 38 percent of students repeating a grade who do not make any significant improvement in mathematics or even get worse. A differentiation according to school types shows that students repeating a grade in integrated comprehensive secondary schools and in schools with several educational levels in particular do not, on average, show any noteworthy improvement in their mathematical literacy. The analysis of the school grades received in mathematics shows that students whose mathematics grades are unsatisfactory do not benefit more from repeating a grade than students whose mathematics performance has been rated as being “satisfactory” or better. The article concludes with a discussion of the possible consequences of changing the way in which repetitions of grades are dealt with.     

Course grades and academic performance by university students: A two-stage least squares analysis

This study employs two-stage least squares to estimate an educational production function for university course grades. The dependent variable is grade for studenti in coursej. Explanatory variables include measures of student aptitude and ability, teacher and course characteristics, and student time allocations to academic endeavors. Results of the study suggest that (1) homework assignments, examinations, and use of a required text increase the time students allocate to a given course; (2) time allocated to a given course has a positive effect on course grade; (3) homework assignments, examinations, and required texts, while increasing time allocated to a given course, have negative effects on course grades; and (4) measures of high school performance, in the presence of controls for mathematical and verbal aptitude, are positively related to the time students allocate to university courses but have no significant independent effect on course grades.     

Supplemental Instruction: Understanding Academic Assistance in Underrepresented Groups

Student retention rates are increasingly important in higher education. Higher education institutions have adopted various programs in the hopes of increasing graduation rates and grade point averages (GPAs). One of the most effective attempts at improvement has been the Supplemental Instruction (SI) program. We examined our SI program relative to three facets: attendance, attendance's influence on final scores, and graduation rates for students who had participated in these courses. These questions were also investigated focusing on specific comparison groups, as we looked into how these effects differed for minority students and nontraditional students compared with those of White and traditional peers. Overall, SI attendance led to positive outcomes— increased final course grades and graduation rates—even after adjusting for previous achievement.     

The Relationship between Assignment Completion and the Attrition and Achievement in Correspondence Courses

Abstract

The relationships between the number of assignments completed by students, whether or not they completed a correspondence course, and their final grades were investigated. The subjects were two separate groups of students enrolled in a correspondence course in fundamental accounting during two consecutive years at the School of Continuing Education, University of Toronto. Students who did more than half of the assignments were significantly more likely to complete the course. Furthermore, the more assignments they submitted, the higher their final examination grade tended to be. Explanation for the observed relationships and suggestions to improve the generally low completion rate in correspondence courses are offered.     

On study habits on an introductory course on programming

Computer aided assessment systems enable the collection of exact time and date information on students’ activity on a course. These activity patterns reflect students’ study habits and these study habits further predict students’ likelihood to pass or fail a course. By identifying such patterns, those who design the courses can enforce positive study habits and to prevent or minimize habits that lead to poor student performance. Hypothetically, by identifying and adjusting the short-term patterns, the teachers might be able to do the same during the course. This publication examines students’ short-term study habits on an introductory level programming course and presents multiple statistically significant connections between students’ assignment submission patterns and their respective final grades. Students who receive the highest grade start and finish their work early, do not work on weekends, and do not work at night, whereas those who fail the course do not show similar behavior but exhibit significant enrichment among those who work large amounts during the night. Course’s mandatory tutorial sessions that act both as assignment release events and as collaborative assignment solving sessions strongly increase assignment submission counts regardless of the students’ final grades and ensure an early start to solving the assignments, possibly preventing those who would otherwise fail the course from starting their work near deadlines.     

The effect of time‐on‐task on student grades and grade expectations

The effects of students’ attitudes on time devoted to a course (i.e. time‐on‐task), and the subsequent effects of this time‐on‐task on their performance in the course and their overall grade point average (GPA) were studied. Over a three‐year period, engineering students (N = 231) were surveyed in weeks one, three, seven (after midterms) and 10 (before finals) of a 10‐week quarter in six sophomore and junior engineering classes (eight different sections). Results of this study show that most students are optimistic about their future performance in a new course, regardless of their previous overall GPA. All students appear to devote a relatively high and equal amount of time‐on‐task during the first week of the term. The students who earned grades between ‘B+’ and ‘A’ appear to optimise this time by the third week. Students who earned a final grade of ‘B’ study similar to ‘A’ students before midterms but significantly increase their efforts after midterms while the ‘C’ students decrease their time devoted to the course. This study finds that ‘A’ students know they will earn an ‘A’ as long as they do the work. In contrast, ‘C’ students are resigned to the fact that they will earn a ‘C’ and, thus, devote far less time to a course. The ‘B’ students want better grades and will devote the most effort towards achieving these grades.     

Influences on peer evaluation in a group project: an exploration of leadership,demographics and course performance

Collaborative learning strategies are widely used in higher education to deepen learning, promote team-building skills and achieve course learning objectives. Using peer evaluation is an important strategy to ensure that engaged and active students are rewarded for their efforts, and to discourage loafing within groups. However, less is known about what biases may influence students’ peer evaluations. In this paper, we investigate what variables students may (consciously or unconsciously) use to evaluate their peers. We explore the role of sex, race, course performance and group leadership on peer evaluation. We also investigate whether these variables correlate with students’ final course grade. We found that students who reported being leaders in groups were evaluated higher than peers who reported being followers, and that course performance positively correlated with peer evaluations. White students received higher peer evaluations than students of colour. This difference reflects trends in group leadership and course performance, with more white students than students of colour reporting being leaders in groups and receiving higher grades.     

Study skills in anatomy and physiology: Is there a difference?

Many factors influence the way individual students study, including but not limited to: previous coursework, attitudes toward the class (motivation, intimidation, risk, etc.), metacognition, and work schedules. However, little of this research has involved medical students. The present article asks the question, “Do individual medical students study differently for different classes?” Study skills surveys were given to United States medical students at an allopathic medical school and an osteopathic medical school. Students were surveyed near the end of their first year gross anatomy course and again near the end of their first year physiology course. Survey items included Likert scale and open‐ended questions about study habits and basic demographic information. The survey responses were correlated with each student's final grade percentages in the courses. Analysis revealed that the four most common study habits were reviewing lecture notes, taking practice examinations, completing learning exercises, and making drawings and diagrams. The two surveys (anatomy and physiology) from each individual were also compared to see if students reported different study habits in anatomy versus physiology. A negative correlation was found between changing study habits between courses and final anatomy grade percentages. Additional analyses suggest that those students who do change their study habits between courses are increasing the number of study strategies that they attempt. This increase in the number of study strategies attempted may not allow the student to reach the same depth of understanding as their colleagues who utilize fewer strategies.

Academic Performance,Age, Gender,and Ethnicity in Online Courses Delivered by Two-Year Colleges

This study investigated the effects the demographic variables age, gender, and ethnicity and their interactions had on academic performance in online courses delivered by public two-year colleges in Kentucky. The study controlled for previous academic performance measured by cumulative grade point average (GPA). The study used a random sample (N = 320) of all students who had enrolled in at least one online course delivered by the institutions of the Kentucky Community and Technical College System in the spring 2008 semester. A linear hierarchical multiple regression acting as ANCOVA served as the main analysis, with the order entry as follows: cumulative GPA; independent variables (age, gender, ethnicity); interaction vectors; and product vectors. Final course grade served as the dependent variable. The results of the analysis indicated that only cumulative GPA was a significant predictor, explaining approximately 40% of the variance of the final grade. Although differences in final grades were present among the variables age and ethnicity, these differences disappeared when controlling for cumulative GPA. Significance of the results and recommendations for future research are discussed.     

The Teaching of Adults

This study examines factors affecting students’ performances in an Introductory Sociology course over five semesters. Employing simple and ordered logit regression models, the author explains final grades by focusing on individual demographic and educational characteristics that students bring into the classroom. The results show that a student's overall grade point average (GPA) and the number of class days missed are significant predictors of performance in the Introductory Sociology course. Findings also identify minority status and grade level as contributory factors in explaining differences in superior performance in the course. Given that the results of this study offer evidence for commonly held assumptions about the positive association between regular class attendance and good grades, it is recommended that students be encouraged to attend more class sessions. The study also confirms that students who do well in an Introductory Sociology course generally do well in other subjects, as validated by their concurrent GPA.
