Evidence of Science and Engineering Practices in Preservice Secondary Science Teachers’ Instructional Planning

There is a current national emphasis on science, technology, engineering, and mathematics (STEM). Additionally, many states are transitioning to the Next Generation Science Standards (NGSS), which encourage teachers to incorporate engineering in science classrooms as well as have their students learn science by doing science. Methods courses are also shifting to adequately prepare preservice science teachers in these areas. This study examines preservice science teachers’ pre- and post-ideal inquiry-based lesson plan scenarios before and after intervention in their Secondary Science Methods I and II courses. These preservice science teachers participated in a variety of opportunities to practice authentic science inquiry (ASI) pedagogical techniques as well as integrated STEM topics, with a particular emphasis on computer programming throughout their 80 h of Methods instruction. ASI is a type of inquiry where students learn science by conducting science research in a grade-appropriate manner. Thirty-eight preservice teachers’ scenarios were analyzed using a rubric from Spuck (2014) to determine the degree to which the ten components of ASI were included in scenarios pre- to post-instruction. Trends in ASI component inclusion are discussed. These findings indicate that preservice science teachers are proficient at writing inquiry-based lessons where they planned opportunities for their future students to collaborate, use scientific instrumentation, and collect and analyze data, but need additional support with developing student activities where students create testable questions, revise their question and methods, participate in peer review, and disseminate their results to their peers or the larger scientific community. Overall, the results suggest Methods instruction should reinforce preservice teachers’ focus on planning lessons which include opportunities for all ASI components. Interventions in the aforementioned areas of weak inclusion may be beneficial to preservice teachers.     

Prospective teachers’ perceptions of development during fieldwork: Tutoring as a vehicle for professional growth

Abstract

This study examines elementary and secondary prospective teachers’ perceptions of the ways in which their experiences as tutors in school‐based tutoring programs influenced their professional development. Data collected from a survey questionnaire, reflective papers, and individual and focus group interviews revealed five main ways that these undergraduate and graduate education students perceived the tutoring experiences contributed to their professional growth. They described development in the following understandings: school students, pedagogical strategies, relationships with colleagues in school settings, the teaching/learning process, and reflective practice. All of these understandings were reported as increasing their self‐confidence as developing educators.     

The collaboration behaviors of scientists in Italy: A field level analysis

The analysis of research collaboration by field is traditionally conducted beginning with the classification of the publications from the context of interest. In this work we propose an alternative approach based on the classification of the authors by field. The proposed method is more precise if the intended use is to provide a benchmark for the evaluation of individual propensity to collaborate. In the current study we apply the new methodology to all Italian university researchers in the hard sciences, measuring the propensity to collaborate for the various fields: in general, and specifically with intramural colleagues, extramural domestic and extramural foreign organizations. Using a simulation, we show that the results present substantial differences from those obtained through application of traditional approaches.     

Factor structure,reliability and validity of the Parental Support for Learning Scale: Adolescent Short Form (PSLS-AS)

Parental involvement in children’s learning has been found to influence academic success. However, very few tools exist for measuring parental involvement, particularly ones that target adolescents’ self-report. The present study assessed the factor structure, reliability and convergent validity of a new scale to assess adolescents’ perceptions of their mothers’ and fathers’ educational involvement: the Parental Support for Learning Scale: Adolescent Short Form (PSLS-AS). The PSLS-AS, as well as a questionnaire measuring the risk of high school drop-out, was administered to a sample of 825 youth (aged 13–14 years). Exploratory factor analysis revealed a two-factor structure representing parental involvement: Controlling Involvement and Autonomy Supportive Involvement. Adolescents’ perceptions of their parents’ involvement correlated with a risk of high school drop-out. Implications and future directions for further validation of the PSLS-AS are discussed.     

A comparison of elementary teacher attitudes and skills in teaching science in Australia and the United States

A study, originally don in Australia in 1983, was replicated in an urban-suburb in the Unitd States. The Australian project vivolved matched pairs of year-fiv teachers in one of two workshops. One workshop taught the skills of teaching electricity, while the other one discussed issues in gender equity in science education (active participation of both girls and boys, comparble student-teacher interactions, and research findings concerning equity). The U.S. study provided three types of workshops (skills, equity and skills, and equity) for comparable groups of fourth and fifth grade teachers. All teachers and their students were subsequently obseved during lessons involving an electricity unit, queried both students and teachers concerning the appropriateness of different fields of science for boys and girls and their interest and aptitudes in doing various types of science. Results from both studies suggest that gender differences in student attitudes toward science may be amellorated by specific types of teacher workshop. Specializations: Gender research, science teacher education, science education national policy. Specializations: Elementary and middle school science education, classroom research. Specializations: Secondary science education, data analysis.     

Facilitating change in undergraduate STEM instructional practices: An analytic review of the literature

This article reviews current scholarship about how to promote change in instructional practices used in undergraduate science, technology, engineering, and mathematics (STEM) courses. The review is based on 191 conceptual and empirical journal articles published between 1995 and 2008. Four broad categories of change strategies were developed to capture core differences within this body of literature: disseminating curriculum and pedagogy, developing reflective teachers, enacting policy, and developing shared vision. STEM education researchers largely write about change in terms of disseminating curriculum and pedagogy. Faculty development researchers largely write about change in terms of developing reflective teachers. Higher education researchers largely write about change in terms of enacting policy. New work often does not build on prior empirical or theoretical work. Although most articles claim success of the change strategy studied, evidence presented to support these claims is typically not strong. For example, only 21% of articles that studied implementation of a change strategy were categorized as presenting strong evidence to support claims of success or failure of the strategy. These analyses suggest that the state of change strategies and the study of change strategies are weak, and that research communities that study and enact change are largely isolated from one‐another. In spite of the weak state of the literature, some conclusions related to the design of change strategies can be drawn from this review. Two commonly used change strategies are clearly not effective: developing and testing “best practice” curricular materials and then making these materials available to other faculty and “top‐down” policy‐making meant to influence instructional practices. Effective change strategies: are aligned with or seek to change the beliefs of the individuals involved; involve long‐term interventions, lasting at least one semester; require understanding a college or university as a complex system and designing a strategy that is compatible with this system. © 2011 Wiley Periodicals, Inc.

The Cognitive Neuroscience of the Teacher–Student Interaction

Pedagogy is the science and art of teaching. Each generation needs to explore the history, theory, and practice of the teacher–student interaction. Here we pave the path to develop a science that explores the cognitive and physiological processes involved in the human capacity to communicate knowledge through teaching. We review examples from our previous work in this research area and discuss a path to reveal the cognitive and cerebral mechanisms by which we teach, unfolding a complex operation such as teaching in its constituents and components.     

Effects of family violence on psychopathology symptoms in children previously exposed to maltreatment

Although many studies suggest that family violence is associated with child psychopathology, multiple features of the home environment might account for this association, such as poverty and caregiver psychopathology. Studies are needed examining how change in psychopathology symptoms is affected by home violence, controlling for children's own developmental symptom histories and other predictors of psychopathology. This study used latent difference score structural equation modeling to test if witnessing home violence and/or experiencing harsh physical discipline predicted changes in psychopathology symptoms among 2,925 youth aged 5-16 years previously exposed to violence. Results demonstrated that harsh physical discipline predicted child-specific changes in externalizing symptoms, whereas witnessing violence predicted child-specific changes in internalizing symptoms across time. Implications for research and policy are discussed.

‘Out of the loop’: early childhood educators gaining confidence with unfamiliar policy discourse

It has been seven years since the Early Years Learning Framework (EYLF) was introduced in Australia and four years since the National Quality Standard (NQS) was implemented. To gain insight into how educators are understanding practice in the Australian early childhood and care context, the study draws on a praxeological frame where educators have the opportunity to inquire and critically reflect on practice in a supported research environment. Data were analysed using critical discourse analysis, enabling a close examination of participant reflections and understandings about practice. Findings reveal that educators are confident when describing their teaching using familiar educational discourse, whereas educators were apprehensive when confronted with new and unfamiliar concepts. The third finding illustrates the ways educators gain confidence with unfamiliar policy discourse. The study’s findings add to limited empirical evidence about how early childhood educators understand key concepts introduced by the EYLF and NQS.
