Development and evaluation of the conceptual inventory of natural selection

Natural selection as a mechanism of evolution is a central concept in biology; yet, most nonbiology‐majors do not thoroughly understand the theory even after instruction. Many alternative conceptions on this topic have been identified, indicating that the job of the instructor is a difficult one. This article presents a new diagnostic test to assess students' understanding of natural selection. The test items are based on actual scientific studies of natural selection, whereas previous tests have employed hypothetical situations that were often misleading or oversimplified. The Conceptual Inventory of Natural Selection (CINS) is a 20‐item multiple choice test that employs common alternative conceptions as distractors. An original 12‐item version of the test was field‐tested with 170 nonmajors in 6 classes and 43 biology majors in 1 class at 3 community colleges. The test scores of one subset of nonmajors (n = 7) were compared with the students' performances in semistructured interviews. There was a positive correlation between the test scores and the interview scores. The current 20‐item version of the CINS was field‐tested with 206 students in a nonmajors' general biology course. The face validity, internal validity, reliability, and readability of the CINS are discussed. Results indicate that the CINS will be a valuable tool for instructors. © 2002 Wiley Periodicals, Inc.

Instructional systems development in the schools

The authors of this commentary take exception to several points made in an article that appeared in the most recent issue of this journal (ETR&D, Vol. 38, No. 2). Following this explanation of their concerns is a reply by the authors of the original article.     

Using qualitative career assessments in career counselling with adults

This article describes what qualitative career assessments are by offering a definition followed by discussion concerning their theoretical base. Emphasis is given to the use of these assessments with adult clients by describing three examples including the LCA, Career Genogram, and Life Role Analysis. Criteria for developing qualitative career assessments as well as for judging the adequacy of existing assessments are provided.     

Long-term Strategic Incrementalism: An Approach and a Model for Bringing About Change in Higher Education

Innovation and reform are crucial to progress, but higher education institutions are by nature highly resistant to change. This article describes long-term strategic incrementalism, an approach to change advocated by L. Cuban, How scholars trumped teachers: Change without reform in university curriculum, teaching, and research, 1890–1990, Teachers College Press, New York, NY, 1999, and proposes a model based on this approach as a proven way of successfully carrying out change within higher education. The approach and model are illustrated through two cases involving reforms—one at the department level and another at the institutional level.

Factors That Influence Self‐Efficacy of Counseling Students: An Exploratory Study

The study examined whether age, prior work experience, number of courses taken, and number of internship hours have a positive relationship with counseling self‐efficacy. Participants were 116 counselor education students. The results from correlation and multivariate analyses of covariance revealed that the length of internship hours and prior related work experience were positively correlated with counseling self‐efficacy. The differences in counseling anxiety, affection adjustment, and assessment found between the students in programs accredited by the Council for Accreditation of Counseling and Related Educational Programs (CACREP) and those in non‐CACREP‐accredited programs disappeared when the background variables were controlled as covariates.     

Attenuation of the CS-preexposure effect after a retention interval in preweanling rats

The effects of flavor preexposure and retention interval were assessed in 6- and 12-day-old rats. Conditioned aversions to a flavor appeared at both ages. The conditioning of the younger pups was unaffected by conditioned stimulus (CS) preexposure and was not evident after a 10-day retention interval. For the 12-day-old rats, preexposure to either the flavor CS or a different flavor attenuated aversion strength when the rats were tested soon after conditioning. Other 12-day-old rats that were tested 10 days after conditioning also expressed substantial aversions, but with a retention interval of this length, the aversions were equivalent for animals preexposed to the CS and those not preexposed before conditioning. This loss of the CS-preexposure effect over a long interval, which has also been observed in adult rats, identifies the locus of this effect as postacquisition and perhaps at the stage of memory retrieval.     

An international collaborative investigation of beginning seventh grade students' understandings of scientific inquiry: Establishing a baseline

Although understandings of scientific inquiry (as opposed to conducting inquiry) are included in science education reform documents around the world, little is known about what students have learned about inquiry during their elementary school years. This is partially due to the lack of any assessment instrument to measure understandings about scientific inquiry. However, a valid and reliable assessment has recently been developed and published, Views About Scientific Inquiry (VASI; Lederman et al. [2014], Journal of Research in Science Teaching, 51, 65–83). The purpose of this large-scale international project was to collect the first baseline data on what beginning middle school students have learned about scientific inquiry during their elementary school years. Eighteen countries/regions spanning six continents including 2,634 students participated in the study. The participating countries/regions were: Australia, Brazil, Chile, Egypt, England, Finland, France, Germany, Israel, Mainland China, New Zealand, Nigeria, South Africa, Spain, Sweden, Taiwan, Turkey, and the United States. In many countries, science is not formally taught until middle school, which is the rationale for choosing seventh grade students for this investigation. This baseline data will simultaneously provide information on what, if anything, students learn about inquiry in elementary school, as well as their beginning knowledge as they enter secondary school. It is important to note that collecting data from all of the approximately 200 countries globally was not humanly possible, and it was also not possible to collect data from every region of each country. The results overwhelmingly show that students around the world at the beginning of grade seven have very little understandings about scientific inquiry. Some countries do show reasonable understandings in certain aspects but the overall picture of understandings of scientific inquiry is not what is hoped for after completing 6 years of elementary education in any country.     

Examining School Psychologists' and Teachers' Application of Approaches Within a Response to Intervention Framework

Approaches consistent with a Response to Intervention (RTI) framework are becoming increasingly prominent. The present study is a preliminary investigation aimed at gaining a greater understanding of educators' knowledge of RTI and application of RTI principles. It serves as the first step toward understanding educators' preparation to implement these mandated changes. Educators (308) completed an online study to assess their knowledge of tasks inherent in RTI procedures. Respondents were asked to rate their familiarity with RTI principles. Then, respondents were asked to interpret graphical data that were consistent with RTI screening and progress monitoring approaches. Overall, results indicated that the majority of educators perceived themselves as having the knowledge to implement RTI practices. However, when asked to apply RTI-consistent principles, not all were successful. Specifically, school psychologists were better at interpreting and making decisions based on graphical data relative to general and special education teachers. There may be a disconnect between the expectations inherent in an RTI model and teachers' ability to meet these expectations. School psychologists may be positioned to support teachers in this area. The implications of these results for implementing RTI practices and developing professional development programs for general and special educators in elementary schools are discussed.
