Developing an empirically based typology of attitudes of entering students toward participation in learning communities

Learning communities (LC) seek to strengthen and enrich students’ connections to each other, their teachers, and the subject matter they are studying. Their success depends on the nature of the learning community program, the learning styles of the students who participate and the reasons why students entered the program. This study uses a combination of factor and cluster analysis to develop a typology of student experiences that is used to examine the efficacy of the Learning Community program at Temple University, Philadelphia. The findings identify distinctive types of learning community experience and show that not all types match well with all students. The study questions the common assumption that learning communities are always helpful to student learning and development, and cautions against the belief that benefits will inevitably accrue. The variation in the value and impact on students of this long‐standing learning community program suggests that the evaluative burden of proof is for administrators to clearly demonstrate and not assume a uniformly positive impact of learning communities.     

Mental health professionals' experiences reporting suspected child abuse and maltreatment

OBJECTIVE: The purpose of this study was to provide systematic data on the experiences of mental health professionals (e.g., psychiatrists, psychologists, and social workers) who reported cases of suspected child abuse and maltreatment concerning their clients. METHOD: Mail surveys were completed by 258 mental health professionals known to have reported a case of suspected child abuse and maltreatment to the New York State Central Register (NYSCR) in 1993. Subjects were asked to complete a survey describing their experience with making reports, referring to a specific case they reported. RESULTS: About 40% did not inform the client about the limits of confidentiality until reportable material came up. Most clinicians reported that informing clients about the limits of confidentiality did not deter them from entering treatment. Many clinicians learned about abuse/maltreatment after approximately 3 months into therapy. Even very experienced clinicians usually consulted with others before making the report. Clinicians most typically informed the client about the report directly and before it was made, but did not call the NYSCR in the presence of the client. Following the report, most clinicians performed additional activities such as calling clients and scheduling additional sessions. When clients evidenced resistance to continuing therapy, it usually dissipated after a brief period of time. In over 72% of the cases, making the report did not disrupt the relationship and in many instances it was helpful in the therapeutic process; about 27% were continuously resistant or terminated therapy shortly after the report was made. CONCLUSIONS: Implications for practice, training, program development, and research are discussed.     

Problem-based learning: student perceptions of its value in developing professional skills for engineering practice

ABSTRACT

This study explores students’ perceptions of the effectiveness of a Problem-Based Learning (PBL) design project, taken as part of a first-year engineering module, in developing professional skills needed for engineering practice. Students completed surveys before and after the PBL group project, and produced personal reflections on the process. The closed survey questions were analysed quantitatively and the main themes from the reflections outlined using General Inductive Analysis. Students rated themselves as having improved across a range of professional skills as a result of the project, with particular emphasis on teamwork, communication skills, understanding of the design process and self-directed learning. In addition, they highlighted improved confidence, as well as new friendships they developed, an important element of a module like this as they transition from secondary to higher education. They were particularly positive about the scaffolded approach taken within the PBL project in terms of its contribution to their learning.     

Fathers' and Mothers' Parenting Predicting and Responding to Adolescent Sexual Risk Behaviors

Transactional models of problem behavior argue that less effective parenting and adolescent problem behaviors coevolve, exerting bidirectional influences. This article extends such models by analyzing growth trajectories of sexual risk behaviors and parenting processes among 3,206 adolescents (aged 13–18) and their residential parents. Within individuals, increases in regular family activities prospectively predicted declines in adolescents' risky sexual activities. In contrast, increases in risky sexual activities predicted heightened father knowledge. Between-individual comparisons revealed bidirectional links between more involved parenting, particularly family activities and father knowledge, and lower adolescent risky sexual activity. Results highlight the importance of family activities as a protective force for adolescents and suggest that fathers may react differently than mothers in the face of youth problem behaviors.     

Exploring the Use of Electroencephalography to Gather Objective Evidence of Cognitive Processing During Problem Solving

Currently, there is significant interest being directed towards the development of STEM education to meet economic and societal demands. While economic concerns can be a powerful driving force in advancing the STEM agenda, care must be taken that such economic imperative does not promote research approaches that overemphasize pragmatic application at the expense of augmenting the fundamental knowledge base of the discipline. This can be seen in the predominance of studies investigating problem solving approaches and procedures, while neglecting representational and conceptual processes, within the literature. Complementing concerns about STEM graduates’ problem solving capabilities, raised within the pertinent literature, this paper discusses a novel methodological approach aimed at investigating the cognitive elements of problem conceptualization. The intention is to demonstrate a novel method of data collection that overcomes some of the limitations cited in classic problem solving research while balancing a search for fundamental understanding with the possibility of application. The methodology described in this study employs an electroencephalographic (EEG) headset, as part of a mixed methods approach, to gather objective evidence of students’ cognitive processing during problem solving epochs. The method described provides rich evidence of students’ cognitive representations of problems during episodes of applied reasoning. The reliability and validity of the EEG method is supported by the stability of the findings across the triangulated data sources. The paper presents a novel method in the context of research within STEM education and demonstrates an effective procedure for gathering rich evidence of cognitive processing during the early stages of problem conceptualization.     

Teachers' Spatial Anxiety Relates to 1st‐ and 2nd‐Graders' Spatial Learning

Teachers' anxiety about an academic domain, such as math, can impact students' learning in that domain. We asked whether this relation held in the domain of spatial skill, given the importance of spatial skill for success in math and science and its malleability at a young age. We measured 1st‐ and 2nd‐grade teachers' spatial anxiety (N = 19) and students' spatial skill (N = 132). Teachers' spatial anxiety significantly predicted students' end‐of‐year spatial skill, even after accounting for students' beginning‐of‐year spatial skill, phonological working memory, grade level, and teachers' math anxiety. Since spatial skill is not a stand‐alone part of the curriculum like math or reading, teachers with high levels of spatial anxiety may simply avoid incorporating spatial activities in the classroom. Results suggest that addressing teachers' spatial anxieties may improve spatial learning in early elementary school.

The relative impact of violation type and lie severity on judgments of message deceitfulness

This paper is part of a larger program of research assessing variables that underlie quantitative deceptiveness ratings. Several recent theoretical approaches, including Information Manipulation Theory (IMT), propose that deceptive messages are best understood as varying along two or more dimensions. At the same time, researchers have increasingly moved from dichotomous deception judgments to continuous deception ratings. This paper questions the validity of scaling degrees of deceptiveness along a single dimension, and argues that gradations in perceived deceptiveness reflect both the type of information manipulated and the severity of the consequences of the deception. This reasoning was tested with alxl experiment (N = 236) in which both the type of information manipulated and the severity of the consequences were systematically varied. As predicted, the results suggest that false messages (i.e., quality violations) are rated as more deceptive than lies of omission (i.e., quantity violations) when lie severity is low, but this difference diminishes as lie severity increases. In other words, false messages were rated as deceptive regardless of severity, but messages omitting information were rated as deceptive as false messages only when the consequences were serious. The implications for measuring deception are discussed.     

A Defense of Publishing Nonsignificant (ns) Results

An argument is advanced for the propositions that a lack of statistically significant findings does not automatically justify rejecting a scientific article for publication or mean that the findings are necessarily uninformative. Systematically declining publication for nonsignificant results leads to negative consequences that include distorting scientific literatures, making hypotheses and theories less falsifiable, depriving meta-analyses of an accurate sample of prior findings, and encouraging questionable research practices. Providing effect sizes and confidence intervals can make findings more informative, regardless of whether the finding is p < .05.
