What is the role of constructivist teachers within faculty communication networks?

Using the biology faculty of one high school (n = 9) and the mathematics faculty of another (n = 16), this study tested the hypothesis that constructivist teachers play an active role within teacher communication networks (the constructivist‐teacher hypothesis). This hypothesis contrasts with the view that constructivist teachers operate alone and largely severed from communications among colleagues. Two types of representations of communication patterns among faculty members (i.e., sociographs) were created and analyzed for each faculty. One type of sociograph plotted communications concerning content/pedagogical issues while the other type plotted social/informal communications. Trained raters assessed constructivist‐teaching practices using the Reformed Teaching Observation Protocol (RTOP). Positive relationships were found between constructivist‐teaching practices and the frequency and significance of communications within both faculties—more so for content/pedagogical issues than for social/informal communications. Importantly, peers sought out constructivist teachers more often than they did traditional teachers, presumably seeking advice regarding teaching practice. Results support the constructivist‐teacher hypothesis and indicate that constructivist teachers are not isolated from their peers. Instead, they appear to play an active role, particularly when colleagues are discussing issues related to content and pedagogy. © 2007 Wiley Periodicals, Inc. J Res Sci Teach 44: 490–505, 2007     

Effects of grading practices and time of rating on student ratings of faculty performance and student learning

The effects of grading practices (strict, lenient) and time of rating (after a lecture, after taking an examination, after receiving feedback on performance on the examination) on student ratings of faculty performance and student learning (i.e., performance on an examination) were assessed in two experimental studies. Results indicated that (1) student ratings were directly affected by grading practices and this effect was a function of the time at which ratings were cornpleted, and (2) student learning and students' ratings of faculty were positively correlated, and grading practices had no effect on student learning. Implications of these findings for the administrative use of student ratings are considered.     

The effects of a problem solving strategy on the achievement of earth science students

A review of the stated goals for education reveals a consistent emphasis on problem solving. Problem solving is compatible with the investigative nature of science and with higher order thinking. Consequently, a problem solving strategy was developed to improve the achievement of eighth grade students enrolled in earth science. The sample consisted of 287 eighth grade students randomly assigned to fourteen sections taught by four teachers. This resulted in seven control sections and seven experimental sections. The students in the treatment groups received approximately six weeks of instruction with the experimental groups receiving a variety of problem solving activities. A forty item posttest consisting of four subtests was administered to all students. The results indicate that the problem solving approach was useful in improving the overall achievement of students. It was particular effective in facilitating application of earth science subject matter. This problem solving approach appears to be a feasible strategy to use in most secondary science classrooms.     

Type of Instructional Material,Cognitive Style and Learning Performance

The positions of 129 14 to 19‐year‐old students on two fundamental cognitive styles dimensions (Wholist‐Analytic and Verbal‐Imagery) were assessed. They then received, by random allocation, one of three versions of a computer‐presented instruction package on home hot water systems. The versions differed in terms of their structure (large versus small step), advance organiser (absent or present), verbal emphasis (high versus low), and diagram type (abstract versus pictorial). Version 1 had large step, no organiser, high verbal content, and abstract diagram. Version 2 had small step, no organiser, low verbal content, and pictorial diagram. Version 3 was identical to Version 2, except that an organiser in the form of an elaborated introduction was given in which all five topics were introduced and each section began with an overview and ended with a summary. There was a significant interaction between version and cognitive style in their effect on recall. The results were discussed in terms of their implications for instruction.     

Transforming an Introductory Programming Course: From Lectures to Active Learning via Wireless Laptops

Within the framework of MIT’s course 1.00: Introduction to Computers and Engineering Problem Solving, this paper describes an innovative project entitled: Studio 1.00 that integrates lectures with in-class demonstrations, active learning sessions, and on-task feedback, through the use of wireless laptop computers. This paper also describes a related evaluation study that investigated the effectiveness of different instructional strategies, comparing traditional teaching with two models of the studio format. Students’ learning outcomes, specifically, their final grades and conceptual understanding of computational methods and programming, were examined. Findings indicated that Studio-1.00, in both its extensive- and partial-active learning modes, enhanced students’ learning outcomes in Java programming. Comparing to the traditional courses, more students in the studio courses received “A” as their final grade and less failed. Moreover, students who regularly attended the active learning sessions were able to conceptualize programming principles better than their peers. We have also found two weaknesses in the teaching format of Studio-1.00 that can guide future versions of the course.     

L'Education Des Enfants Des Travailleurs Migrants En Suisse

Swiss policy vis-à-vis children of migrant workers has two objectives: promoting their integration in the Swiss educational system and permitting to a certain extent, efforts to preserve their linguistic and cultural identity. The authors analyse the policy measures and their educational objectives for each stage of education.     

Impact of a Brief Literacy Intervention on Urban Preschoolers

A pre-post study was conducted at an urban child-care center to study the hypothesis that a brief literacy intervention would result in improved receptive vocabulary for preschoolers. Parents attended a series of 4 workshops about reading to children. The children had a significant 7-point increase in their Peabody Picture Vocabulary Test scores at 7-month follow-up. Children of college-educated parents had a higher increase in scores than did children whose parents were not college educated.     

Creative block play

Blocks should be part of the daily free choice activity in early childhood settings for children between the ages of two and six. Large enough segments of time need to be allotted for blockbuilding activities, so that children can build various structures and also have enough time to use blocks for social and dramatic play.
