Constructivism: Defense or a Continual Critical Appraisal A Response to Gil-Pérez et al.

This commentary is a critical appraisal of Gil-Pérez et al.'s (2002) conceptualization of constructivism. It is argued that the following aspects of their presentation are problematic: (a) Although the role of controversy is recognized, the authors implicitly subscribe to a Kuhnian perspective of `normal' science; (b) Authors fail to recognize the importance of von Glasersfeld's contribution to the understanding of constructivism in science education; (c) The fact that it is not possible to implement a constructivist pedagogy without a constructivist epistemology has been ignored; and (d) Failure to recognize that the metaphor of the `student as a developing scientist' facilitates teaching strategies as students are confronted with alternative/rival/conflicting ideas. Finally, we have shown that constructivism in science education is going through a process of continual critical appraisals.     

Personal Research Sets the Stage for Change

Starting in 2011, implementation of Personal Research Sessions, or PRS, not only showed librarians at the College of the Holy Cross the success of one-on-one research appointments, but also led the reference program on a path of service-centered changes. This path includes fewer hours on the physical desk, a system of on-call reference shifts, an increase in reference student worker training, a semester-to-semester increase in PRS, and new goals for assessment. The authors discuss the state of student research at Holy Cross and their approach to reference service.     

Working memory, fluid intelligence, and science learning

A review of the history of working memory (WM) studies finds that the concept of WM evolved from short-term memory to a multi-component system. Comparison between contemporary WM models reveals: (1) consensus that the content of WM includes not only task-relevant information, but also task-irrelevant information; (2) consensus that WM consists of phonological and visuospatial components; (3) consensus that short-term memory storage is a function of WM; (4) disagreement as to whether an independent executive control is a necessary WM component; and (5) disagreement as to whether the control function is active or passive. Methods for measuring WM differed across studies with a preponderance of various dual-tasks; little psychometric work has been done on these measures. Correlational studies supported a close relationship between WM and measures of fluid intelligence and science achievement, but we found no experimental studies on the impact of WM training on science achievement. Finally we suggest how WM research findings may be applied to improve fluid intelligence and science achievement.     

Competency Maps: an Effective Model to Integrate Professional Competencies Across a STEM Curriculum

Curricula designed in the context of the European Higher Education Area need to be based on both domain-specific and professional competencies. Whereas universities have had extensive experience in developing students’ domain-specific competencies, fostering professional competencies poses a new challenge we need to face. This paper presents a model to globally develop professional competencies in a STEM (science, technology, engineering, and mathematics) degree program, and assesses the results of its implementation after 4 years. The model is based on the use of competency maps, in which each competency is defined in terms of competency units. Each competency unit is described by a set of expected learning outcomes at three domain levels. This model allows careful analysis, revision, and iteration for an effective integration of professional competencies in domain-specific subjects. A global competency map is also designed, including all the professional competency learning outcomes to be achieved throughout the degree. This map becomes a useful tool for curriculum designers and coordinators. The results were obtained from four sources: (1) students’ grades (classes graduated from 2013 to 2016, the first 4 years of the new Bachelor’s Degree in Informatics Engineering at the Barcelona School of Informatics); (2) students’ surveys (answered by students when they finished the degree); (3) the government employment survey, where former students evaluate their satisfaction of the received training in the light of their work experience; and (4) the Everis Foundation University-Enterprise Ranking, answered by over 2000 employers evaluating their satisfaction regarding their employees’ university training, where the Barcelona School of Informatics scores first in the national ranking. The results show that competency maps are a good tool for developing professional competencies in a STEM degree.     

A Study of Faculty Perceptions of Summer Compressed Course Teaching

Students take summer and compressed courses for a variety of reasons and research indicates that learning outcomes in these courses are similar to those gained in traditional semester or quarter courses. This quantitative study was an attempt to clarify faculty perceptions about summer compressed courses. One hundred and fifty-one faculty members teaching at a large, multicampus institution completed a survey addressing teaching methodology, approaches to student assessment, and other pedagogical issues relating to such courses. It was determined that many faculty did make adjustments in teaching methods and approaches to student assessment. In addition, perceptions were different between experienced/tenured faculty and inexperienced/nontenured faculty.Mark Kretovics is an Assistant Professor of Higher Education Administration and Student Personnel at Kent State University. He received his Ph.D. from Colorado State University and his research interests include the assessment of student learning, business practices in higher education, distance education, and pedagogical issues in compressed courses. Mark had over 20 years of administrative experience within higher education before transitioning into his current faculty role. Alicia R.

Sleep,Classroom Behavior,and Achievement Among Children of Color in Historically Disinvested Neighborhoods

Children of color are more likely to have poor sleep health than White children, placing them at risk for behavioral problems in the classroom and lower academic performance. Few studies, however, have utilized standardized measures of both classroom behavior and achievement. This study examined whether children’s sleep (parent and teacher report) in first grade concurrently related to independent observations of classroom behavior and longitudinally predicted achievement test scores in second grade in a sample of primarily Black (86%) children (n = 572; age = 6.8) living in historically disinvested neighborhoods. Higher teacher-reported child sleepiness was associated with lower adaptive behaviors and higher problem behaviors in the classroom, and predicted lower achievement. Parent-reported bedtime resistance and disordered breathing also predicted lower achievement.
