This study aimed to examine the effect of using items from previous exams on students? pass-fail rates and on the psychometric properties of the tests and items. The study included data from 115 tests and 11,500 items used in the midterm and final exams of 3,910 students in the preclinical term at the Faculty of Medicine from 2014 to 2019. Data…

Algebra is the language that must be mastered for any course that uses math because it is the gateway for entry into any science, technology, engineering, and mathematics (STEM) discipline. "Math Remediation for the College Bound" fosters mastery of critical math and algebraic concepts and skills essential to all of the STEM disciplines and some…

Algebra is the language that must be mastered for any course that uses math because it is the gateway for entry into any science, technology, engineering, and mathematics (STEM) discipline. This book fosters mastery of critical math and algebraic concepts and skills essential to all of the STEM disciplines and some of the social sciences. This…

As a classroom teacher, Kari Smith realized that traditional objective tests don't always assess what students actually know. But tests are so deeply embedded in the education system that it would be difficult to do away with them entirely. Smith decided to make tests into learning tools. In this article, Smith describes three strategies for…

Use of end-of-chapter textbook problems for teaching and assessing concepts in introductory physics is widespread, as is restriction of student access to the solutions. Surveys student attitudes (n=128) on access to problem solutions, sampling the enrollment in a large calculus-level course. Results confirm a definite preference for freer access…

Collects and examines data on the attitudes of physics instructors towards allowing student access to textbook problem solutions. Student data (n=227) was collected by survey. Compares student and instructor attitudes and discusses the possible significance of the survey results. (Author/MVL)

This document consists of three modules concerned with aspects of statistics. The first provides knowledge of the effect of imperfect correlation and random error on differences between means, and the reasons for the necessity of random allocation of objects to experimental and control conditions in scientific experimentation. The second unit…

This study retrospectively applies aggregate scoring to the cardiology questions from a recertifying examination in general internal medicine. Three groups of experts were identified among the examinees and the remainder of the examinees were the participants (N=1887) of the study. Generalizability theory is applied to these data. (MLW)

Describes the Key Groups that is a 40-60 minute exercise centering on student-led groups that create an answer key to a quiz that the students have taken immediately before the exercise. Recommends using Key Groups because this exercise helps students develop leadership skills and task-group membership. (CMK)

The effect that student ability level has on receiving feedback following classroom tests was studied. Forty-four undergraduates enrolled in four educational psychology classes were assigned to low or high ability groups based on their total score from the first four exams. Two classes were trained in a feedback technique, and the remaining two…

The emphasis is on so-called "best solution" problems to questions that frequently arise in practical situations, such as finding an answer for the least amount of time, greatest volume, least amount of work, maximum profit, and minimum cost. One of this module's purposes is to help users become acquainted with the types of calculations necessary…

This document contains two units that examine integral transforms and series expansions. In the first module, the user is expected to learn how to use the unified method presented to obtain Laplace transforms, Fourier transforms, complex Fourier series, real Fourier series, and half-range sine series for given piecewise continuous functions. In…

This document contains three modules. The first of these examines applications of algebra to geometry. It is designed to teach students how to algebraically characterize points which may be constructed with a compass and straight edge, and how to use this characterization to obtain classical geometric nonconstructibility results. The second unit…

The document notes that in health and medical research the need to compare rates or proportions for some event can often occur. It is the module's goal to illustrate the conditions necessary for recognizing potentially misleading situations, and to show how to cope statistically with such situations. The four sections show: 1) when to adjust…

A group is viewed to be one of the simplest and most interesting algebraic structures. The theory of groups has been applied to many branches of mathematics as well as to crystallography, coding theory, quantum mechanics, and the physics of elementary particles. This material is designed to help the user: 1) understand what groups are and why they…
