Using Web-Based Key Character and Classification Instruction for Teaching Undergraduate Students Insect Identification

The purpose of the study was to determine whether undergraduate students receiving web-based instruction based on traditional, key character, or classification instruction differed in their performance of insect identification tasks. All groups showed a significant improvement in insect identifications on pre- and post-two-dimensional picture specimen quizzes. The study also determined student performance on insect identification tasks was not as good as for family-level identification as compared to broader insect orders and arthropod classification identification tasks. Finally, students erred significantly more by misidentification than misspelling specimen names on prepared specimen quizzes. Results of this study support that short web-based insect identification exercises can improve insect identification performance. Also included is a discussion of how these results can be used in teaching and future research on biological identification.     

Examining the Validity of Standards-Based Assessments for Initially Fluent Students and Former English Language Learners

To date, assessment validity research on non-native English speaking students in the United States has focused exclusively on those who are presently English language learners (ELLs). However, little, if any, research has been conducted on two other sizable groups of language minority students: (a) bilingual or multilingual students who were already English proficient when they entered the school system (IFEPs), and (b) former English language learners, those students who were once classified as ELLs but are now reclassified as being English proficient (RFEPs). This study investigated the validity of several standards-based assessments in mathematics and science for these two student groups and found a very high degree of score comparability, when compared with native English speakers, for the IFEPs, whereas a moderate to high degree of score comparability was observed for the RFEPs. Thus, test scores for these two groups on the assessments we studied appear to be valid indicators of their content knowledge, to a degree similar to that of native English speakers.     

Estimating the Effect on Grades of Using Multiple-Choice Versus Constructive-Response Questions: Data From the Classroom

This study investigates the degree to which grades based solely on constructed-response (CR) questions differ from grades based solely on multiple-choice (MC) questions. If CR questions are to justify their higher costs, they should produce different grade outcomes than MC questions. We use a data set composed of thousands of observations on individual students in introductory economics classes at a large public university. We note that the instructors of these classes made conscientious efforts to write CR questions that assessed higher levels of learning (Bloom, 1956 Bloom, B. S. 1956. Taxonomy of educational objectives: The classification of educational goals, handbook 1: Cognitive domain. New York: McKay..  [Google Scholar]). Despite this, we find relatively little difference in grade outcomes. Our analysis suggests that switching from an all-CR assessment to an all-MC assessment would produce grade variations that are similar to the differences that are observed for students across different tests. Although other studies have focused on test scores, frequently AP test scores, our study is the first to focus attention on university grades. We hope that our inability to identify substantial benefits to CR questions in terms of grades will stimulate further research to identify substantive benefits from using the more costly CR questions.     

Confirming the Factor Structure of the Cognitive Test Anxiety Scale: Comparing the Utility of Three Solutions

This study validated the factor structure of a popular assessment of learner's cognitive test anxiety. Following recent findings in a study with Argentinean students' use of the Spanish version of the Cognitive Test Anxiety Scale (CTAS), this study tested the factor structure using data from 742 students who completed the original English version in the United States. Comparison of three confirmatory factor analyses confirmed the prior finding that reverse-coded items included in the original CTAS produced a second factor that did not add to the model fit for the CTAS. In addition, the results identified that a reduced length (17-item) version of the CTAS that removed all reverse-coded items was preferable to the two-factor solution for the full scale. Implications for assessment of test anxiety as well as the use of reverse-coded items in self-report survey research are discussed.     

THE ROLE OF COMMUNITY COLLEGES IN THE TRAINING AND EDUCATION OF LAW ENFORCEMENT AND CORRECTIONS PERSONNEL: A CURRICULUM FOR THE 21st CENTURY

Community colleges are in a unique position to meet the education and training needs of law enforcement and corrections personnel for the next century. The nature of the community college allows the proper blend of vocational and formal education in the design of a common curriculum to meet the needs of law enforcement. Location and cost also become factors as agencies attempt to stretch their training budgets. The community colleges have the flexibility and the resources to meet the needs of law enforcement for a practical, affordable, quality, and achievable education for employees in pre‐service, academy, and in‐service status.
