Assessing students’ understanding about levers: better test instruments are not enough

This study was designed to investigate variations in students’ responses to lever problems across multiple assessment contexts and formats. Prior to and at the end of a four‐month science unit on simple machines, grade 6/7 students prepared semantic maps, wrote responses to application questions, discussed their written answers, and modelled solutions to practical problems using physical materials. We present data from pre‐ and post‐instruction interviews to show that students’ responses varied in kind and extent across assessment contexts and formats. Such variations in performance are consistent with situated cognition theories which assert that competence is heterogeneous across situations and is a function of interactions between individuals and the contexts in which they perform. Based on these findings, implications are drawn regarding more productive means of assessing students’ understanding in classrooms.     

Exploring perceived support of postgraduate medical science research students

There is still much to learn about the support required by postgraduate research students, across academic disciplines, to facilitate successful completion of a research degree. The primary aim of this study was to explore postgraduate medical science research students’ perceptions of academic and mentoring support at different stages during their degree programme. A second aim was to explore the feasibility and acceptability of peer mentoring as a strategy to enhance student support in this population. A mixed method study design was used. Students first completed an online questionnaire, which was then supplemented with focus group discussion to explore emergent findings in greater depth. The main results indicated that the nature and quality of academic supervision support have a significant influence on research student training and development. ‘Functional’ and ‘relationship development’ concepts of supervisory styles were highlighted as important aspects to perceived support in this research population. The main facilitators to enhance academic support were effective communication, project planning and timely feedback. There was a high degree of acceptability for a peer mentoring programme as a complementary approach to enhance student support. Peer mentoring psychosocial functions such as friendship, counselling and career guidance were considered potentially beneficial to enhancing student support. Students also discussed peer coaching as central to their learning and research skill development. This work is a useful starting point to explore perceptions of research student support in the target population. Further work is required to develop strategies to enhance student support in academic practice.     

Against the Generation Gap: Thinking “Otherwise” about Adolescence

Prevailing cultural views of adolescence are the product, this article argues, of a long, multidimensional process of social construc-tion. Employing a double reading of this process, this article analyzes the difficulties religious educators face on account of the reified nature of this social construction. Drawing on philosophical and psychological understandings of human flourishing, this article presents and argues for a different way of thinking about adolescents and the religious congregation's role in religious education.     

Learning the words AND knowing the concepts: an in‐depth study of one expert teacher's use of language as a cultural tool to support inquiry

This research explored the practices of one science teacher, expert in her field, as she worked to enact science discourse that incorporated language in naturalistic and rigorous ways. Difficulties in mastering the language of science contribute to troubling and persistent achievement gaps across demographic and gender groups. Science learning is based in discourse, with knowledge built by asking questions, exploring, revising views and asking new questions. But all too often students are not able to participate fully in these opportunities for discourse that is engaging and exploration due to the difficulty of science language. Qualitative analysis of this teacher's use of science discourse to establish clear links between essential science language and concepts and pre/post analysis of a science language assessment reveal important ways that teachers and researchers can work together to design and deliver instruction and assessment that supports students' mastery of sophisticated language and concepts. Results have implications for theory regarding science discourse; language learning, and conceptual development; and provide a model for teacher–researcher partnerships exploring important problems of teaching practice.     

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.
