A Campus-Wide Study of STEM Courses: New Perspectives on Teaching Practices and Perceptions

At the University of Maine, middle and high school science, technology, engineering, and mathematics (STEM) teachers observed 51 STEM courses across 13 different departments and collected information on the active-engagement nature of instruction. The results of these observations show that faculty members teaching STEM courses cannot simply be classified into two groups, traditional lecturers or instructors who teach in a highly interactive manner, but instead exhibit a continuum of instructional behaviors between these two classifications. In addition, the observation data reveal that student behavior differs greatly in classes with varied levels of lecture. Although faculty members who teach large-enrollment courses are more likely to lecture, we also identified instructors of several large courses using interactive teaching methods. Observed faculty members were also asked to complete a survey about how often they use specific teaching practices, and we find that faculty members are generally self-aware of their own practices. Taken together, these findings provide comprehensive information about the range of STEM teaching practices at a campus-wide level and how such information can be used to design targeted professional development for faculty.     

Name writing and letter knowledge in preschoolers: Incongruities in skills and the usefulness of name writing as a developmental indicator

In this study, 114 preschoolers (M age = 53 months) completed a battery of literacy assessments to explore the interplay between name writing and letter knowledge in early literacy learners. Name writing was significantly related to children's letter knowledge, and the relationships were moderate to high. However, many children exhibited an incongruity in name writing and name-specific letter-recognition skills (i.e., they could write their names but not recognize the letters in their names, or recognize the letters in their names but not write them). When these two groups were contrasted statistically, the children with superior name-specific letter recognition (but poorer name writing scores) had significantly higher letter knowledge scores than the children with superior name writing scores (but poor name-specific letter-recognition scores). Writing one's name, in itself, did not appear to correspond to a literacy advantage. Thus, with regard to the recommendation that name writing be used as a literacy assessment tool in preschool, the results from this study suggest that name writing should be used as a measure of mechanical skill only and should not be used as a means to assess children's conceptual knowledge (of letter names, letter sounds, or the alphabetic principle).     

STUDENT INTEREST IN TECHNOLOGY AND SCIENCE (SITS) SURVEY: DEVELOPMENT,VALIDATION, AND USE OF A NEW INSTRUMENT

This study presents the systematic development, validation, and use of a new instrument for measuring student interest in science and technology. The Student Interest in Technology and Science (SITS) survey is composed of 5 sub-sections assessing the following dimensions: interest in learning science, using technology to learn science, science careers, technology careers, and attitudes toward biotechnology. Our development process included review of existing instrumentation, pilot testing, and expert panel review. The resulting instrument was administered before and after implementation of a biotechnology intervention which used a computer-based game to engage learners in the use of biotechnology to address a societal issue. We employed item response theory (IRT) to explore instrument validity and precision. Results of the psychometric analyses suggest that the SITS survey has a well-defined structure and meets IRT assumptions. Difficulty and discrimination parameters as well as reliability analyses indicate that SITS items provide useful measures of student interest. Finally, we use the SITS to explore the extent to which the intervention used in this study supports changes in student interest and association between students’ interest and related content knowledge. Implications for the future use of this instrument are discussed.     

Instructional redesign: Developing learning communities in academia

Traditionally, learning is provided in a unidirectional manner from instructor to learner. This practice can be limiting to all individuals involved in the learning process. To develop quality instructional materials, the learning team can participate in instructional design and development (ID) as partners. This article discusses a proposed learning community to be created during the process of course redesign. Human performance technology and ID professionals who use learning community practices can improve their designs by including all relevant stakeholders.
