Predicting genetics achievement in nonmajors college biology

Students enrolled in a non-majors college biology course were pretested to determine their level of intellectual development, degree of field independence, mental capacity, amount of prior genetics knowledge, and amount of fluid intelligence. They were then taught a unit on Mendelian genetics. The only student variables found to not account for a significant amount of variance on a test of reading comprehension and/or a test of genetics achievement was amount of prior genetics knowledge. Developmental level was found to be the most consistent predictor of performance, suggesting that a lack of general hypothetico-deductive reasoning ability is a major factor limiting achievement among these students.     

Biomechanics of elite recumbent handcycling: a case study

In the presented research, a kinematic and electromyographic study was performed on one world-class male elite handbiker (UCI class H3.2). Activity of 14 muscles of the upper body were measured with surface electromyography (EMG), and a motion analysis of the athlete’s movement was performed concurrently for different backrest positions, crank lengths, and crank heights at three power levels (130, 160 and 190 W). Kinematics in terms of elbow and wrist angle, muscular on-off timing, EMG amplitudes, and integrated EMG were calculated. Results showed that little changes occurred for kinematic parameters and changes in position led to a shift in muscular timing. However, no indication for immediate improvement to the athlete’s preferred original position could be observed.     

Use of reasoning to a contradiction in grades three to college

The primary purpose of this study was to test the hypothesis that an important intellectual acquisition during adolescence is the ability to generate arguments that involve reasoning to contradiction. Students in grades 3, 5, 7, 9, 11, and college were individually administered a four-card selection task that required them to, among other things, reason to a contradiction to falsify a hypothesis. Virtually none of the students spontaneously utilized this reasoning pattern on the initial task. Minimal verbal instruction in use of the reasoning pattern was then given followed by a logically analogous selection task. Performance on this task improved significantly with age from 12% success among third graders to 52% success among college students, providing some support for the hypothesis. Performance on an evaluation task showed similar rates of success; however, most students were able to correctly evaluate falsifying evidence when presented. This result suggested that, contrary to Piagetian theory, students from grade 3 upward comprehend the logic of falsification. It is argued that reasoning to a contradiction is a reasoning pattern of central importance in testing alternative scientific hypotheses and its use in students grades 3 through college could be enhanced through proper instruction and, if done, should increase students' ability to generate and evaluate competing hypotheses.     

DigitalHub: A Repository Focused on the Future

The DigitalHub scholarly repository was developed and launched at the Galter Health Sciences Library for the Feinberg School of Medicine and the greater Northwestern Medicine community. The repository was designed to allow scholars the ability to create, share, and preserve a range of citable digital outputs. This article traces the evolution of DigitalHub’s development and engagement activities, highlighting project challenges, innovations, success stories, and the team-based approach that was employed to successfully achieve project goals.     

Advancing research beyond the ruling theory stage

Seldom do researchers in science education state causal hypotheses they seek to test. Even less often are alternative hypotheses stated, much less tested. Further, science education researchers as a rule confuse hypotheses with predictions. Thus, they stand little chance of conducting research which distinguishes among alternative explanations, and consequently stand little chance of advancing knowledge beyond the Ruling Theory Stage of thinking. The present article offers five research criteria and their rationale intended to help researchers avoid these problems and help them conduct higher-quality research, which should in turn improve the quality of science teaching.     

Why use learning outcomes in higher education? Exploring the grounds for academic resistance and reclaiming the value of unexpected learning

Learning outcomes are now mandated in higher education courses across Europe. However, their impact on teaching and student learning is both uncertain and an issue for debate. In this paper, we explore (1) what is meant by learning outcomes in diverse contexts and (2) whether policy and practice governing learning outcomes accord with developments in learning theories, especially regarding sociocultural approaches that have drawn significant interest since the 1990s (Engeström 1987; Lave and Wenger 1991). Shepard’s (Educational Researcher, 29(7), 4–14, 2000) publication is particularly salient to our examination due to her identification of an emerging paradigm to assist in the understanding of the relationships among teaching, learning and assessment. Employing recent work on conceptualisations of learning outcomes and a four-quadrant taxonomy (Prøitz in Educational Assessment, Evaluation and Accountability, 22(2), 119–137, 2010, 2014), we discuss relevant learning theory approaches. This article is a conceptual investigation exploring the grounds for the assumption that learning can be predefined in terms of (expected) outcomes. Specifically, we discuss this assumption from the perspective of recent developments in learning theories. We argue that introducing learning outcomes predominantly for policy and management purposes may actually weaken the learning outcomes’ potential to direct teaching and learning and to improve the quality of both.     

Impact of European projects on engineering education

Various European programmes represent invaluable help and source of experience for universities in Central and Eastern Europe. Being an emerging university that was established just 8 years ago, we welcomed the chance to be involved in numerous projects that introduced us to the area of European cooperation. Last summer two very interesting projects concerning our university were finished (in terms of financing from the sources mentioned above) and so it is a good occasion to evaluate the progress of our international co-operation in the last 3 years and to look forward towards further development of our established links. The first project was financed by The British Know How Fund and its aim was to bring together the University of Hull, UK, and the Faculty of Informatics and Management UHK in Hradec KrÁlové (FIM). The second project, called INSYPA, was a Joint European Project within the frame of the TransEuropean Mobility Programme for University Studies (Tempus). Both projects were extremely fruitful for us but so different one from another that we think it might be interesting to compare them. The contribution describes our original plans, their development, evolution of our partnership, the problems which arose and were solved. The main stress is given to expertise obtained, methods of assessment, persistent links and their influence on our integration to EU educational and research programmes.     

Reformed undergraduate instruction and its subsequent impact on secondary school teaching practice and student achievement

The Arizona Collaborative for Excellence in the Preparation of Teachers (ACEPT) Program is one of several reform efforts supported by the National Science Foundation. The primary ACEPT reform mechanism has been month‐long summer workshops in which university and community college science and mathematics faculty learn about instructional reforms and then attempt to apply them in their courses. Previous ACEPT evaluation efforts suggest that, when implemented, the reforms boost undergraduate student achievement. The initial purpose of the present study was to discover whether enrollment of preservice teachers in one or more of these reformed undergraduate courses is linked to the way they teach after they graduate and become in‐service teachers. Assuming that a link is found, a second purpose was to discover whether the presumed positive effect is in turn linked to their students' achievement. In short, the answer appears to be yes, at least among the biology teachers and students surveyed. Compared with controls, the biology teachers who had enrolled in one or more ACEPT reformed course during their teacher preparation program demonstrated significantly higher scores on the measure of reformed instruction and their students demonstrated significantly higher achievement in terms of scientific reasoning, nature of science, and biology concepts. These results support the hypothesis that teachers teach as they have been taught. Furthermore, it appears that instructional reform in teacher preparation programs including both methods and major's courses can improve secondary school student achievement. © 2003 Wiley Periodicals, Inc.
