High failure rates in introductory college science courses, including anatomy and physiology, are common at institutions across the country, and determining the specific factors that contribute to this problem is challenging. To identify students at risk for failure in introductory physiology courses at our open-enrollment institution, an online…

Recent reform efforts in undergraduate biology have recommended transforming course exams to test at more cognitively challenging levels, which may mean including more cognitively challenging and more constructed-response questions on assessments. However, changing the characteristics of exams could result in bias against historically underserved…

The students' performance in various types of problems dealing with the conservation of matter during chemical reactions has been investigated at different levels of schooling. The participants were 499 ninth grade (ages 14, 15 years) and 624 eleventh grade (ages 16, 17 years) Greek students. Data was collected using a written questionnaire…

Many college science educators have moved away from the traditional lecture format and toward learner-centered classroom environments. Yet many of us struggle to cover large content loads, reverting at times to rote memorization. This paper suggests rote memorization simply does not work and students must be actively engaged to learn. (Contains 1…

Purpose: The purpose of this scientific monograph is to show new and creative approaches to different school subjects in primary and secondary level. Methodology: Interdisciplinary and international comparative approaches were used. Now according to the 7th Framework Program, the preferred form of Science Education (www.scientix.eu) is preferred…

This article discusses the author's observation that in his thirty-plus years in academics, many students who, by natural ability, interest, and work ethic, should have performed well in the sciences, but performed poorly. Many of these students are operating at the bottom rungs of Bloom's taxonomy (ladder), while college professors and industrial…

Classificatory behavior of 41 fourth graders enrolled in a science program at the National Zoological Park in Washington, D.C. was assessed on an instrument adapted from Piaget's interviews with children on class inclusion. Developmental levels were related to student performance in the program. Data analysis shows that students with a high…

Cluster analysis was used to classify 257 fifth and sixth graders on the basis of their mastery, ego, and work-avoidant goal orientations. Results identify three clusters with different achievement profiles in science. Students for whom mastery goals were stronger than the other goals show the most positive achievement. (SLD)

Discussed is whether embedding generative cognitive strategies in microcomputer courseware improves student performance on cognitive assessment measures and on insect classification tasks. The effects of transactional software on students' knowledge of insect anatomy and principles of insect classification were also investigated. (KR)

This paper advocates categorization of engagement on the basis of a logical relationship with the outcomes of a study and the use of student attributes that are logically related to engagement and/or achievement as covariables. Results from a study involving nine engagement categories, measures of formal reasoning ability, locus of control and…
