Predictive validity of my class inventory

A recent guest-edited issue of this journal (Volume 6, Number 3, 1980) summarizes the considerable interest evident since the late 1960s in the conceptualization, assessment, and study of student perceptions of psychological characteristics of their classroom learning environment. This issue and several other recent key overviews (Moos, 1979; Walberg, 1979; Fraser, 1981; Fraser and Walberg, 1981) have firmly established classroom environment as a thriving field of study.When used as criterion variables in prior curriculum evaluation research, student perceptions of classroom environment characteristics have differentiated revealingly, usefully, and appreaciably between classrooms following alternative curriculum materials or instructional strategies (Anderson, Walberg, and Welch, 1969; Levin, 1980). In addition, other studies have established the criterion validity of classroom environment perceptions in differentiating between classrooms varying in class size (Walberg, 1969), grade level (Welch, 1979), and subject matter (Anderson, 1971a; Hearn and Moos, 1978), and between classrooms in five different types of schools (urban, rural, suburban, vocational, alternative) (Trickett, 1978). The strongest tradition in past research on classroom learning environment, however, has involved investigation of the predictive validity of student perceptions (i.e., the ability to predict student cognitive, affective, and behavioral learning outcomes).     

A comparison of actual and preferred classroom environments as perceived by science teachers and students

This study of perceptions of classroom environment is distinctive in that, first, it made use of two instruments (the Individualized Classroom Environment Questionnaire and Classroom Environment Scale) which have had very little use in prior science education research and, second, it involved assessment not only of student perceptions of actual environment, but also of student perceptions of preferred environments and teacher perceptions of actual environment. Administration of these instruments to a sample of 2175 junior high school students in 116 classes revealed that the environment scales exhibited satisfactory internal consistency reliability and discriminant validity in each of the three forms (student actual, student preferred, and teacher actual), and that there were some fascinating systematic differences between the profiles of environment scale scores obtained for the different forms. In particular, it was generally found that students preferred a more favorable classroom environment then was perceived as being actually present and that teachers perceived the environment of their classes more favorably than did students in the same classrooms.

What do individuals in different science groups within a life sciences organization think about genetic modification?

An assessment was undertaken of the attitudes of individuals within the science community towards a program to produce genetically modified cattle for altered milk composition, expectantly allowing for research into the treatment of multiple sclerosis in humans. The majority of respondents to an electronic survey expressed favorable attitudes to the program, thought it beneficial, respected individual freedom and was fair and just and disagreed that it was harmful. A passion for science and having a suitable lifestyle were the most important motivating factors for individuals. Finally, there were a wide range of responses to a number of cultural beliefs or myths. Science grouping significantly affected the responses. Compared with Systems and Land groups, Plant and Reproduction groups more strongly agreed with the project, thought it less harmful to interest groups, felt that genetic modification of animals was more morally acceptable, and more strongly agreed with the myth statements. These results indicate a diversity of beliefs and attitudes towards genetic modification amongst those within the science community, and highlight the importance of understanding ethics and myths in dealing with them. It is suggested that the diversity of beliefs could be better used to help shape public policy and understanding of biotechnology.     

From spontaneous to instrumental behavior: kinematic analysis of movement changes during very early learning

3-month-old infants who can activate a mobile with their spontaneous leg kicks increase their kick rate over baseline. Kinematic analyses of the temporal and topographic characteristics of reinforced leg kicks were compared with those of infants who saw noncontingent mobile movement. In both experimental and control groups, the flexion and extension movement phases of the kick remained remarkably invariant in duration. Pauses between movements varied inversely with rate. Kick amplitude increased with increasing rate except in the extinction phase, where in some infants, kicks became less frequent but more forceful. Movement duration was unaffected by reinforcement condition. By varying amplitude and frequency domains, infants adjusted movement by neuromuscular mechanisms similar to those of mature humans. The experimental imposition of a voluntary component on spontaneous kicking did not alter the modifiability of the movement control parameters.     

The “Autodidact”, the Pursuit of Subversive Knowledge and the Politics of Change

This paper contrasts two types of “autodidact” located in the UK in different historical periods, which utilised different learning/research technologies to different ends. From the 1920s to the 1960s some working-class activists committed to the Communist Party of Great Britain became “educated” in Marxism (and more) through the processes intrinsic to their politics. This radical acculturation was undertaken outside the universities in consequence of both an absence of access to higher education and because of the relatively enclosed social world of British Communism. The widening of educational opportunities and the decline of political Marxism effectively extinguished this kind of autodidact. New technologies have meant that the 21st century is witnessing individuals and cyber-communities that are creating knowledge-based challenges to professional and institutional power in the face of personal/family “medical” crises. The paper outlines the characteristics of these two categories of autodidact and a new terrain of counter-hegemonic learning.     

Intelligence and Neurophysiological Markers of Error Monitoring Relate to Children's Intellectual Humility

This study explored developmental and individual differences in intellectual humility (IH) among 127 children ages 6–8. IH was operationalized as children's assessment of their knowledge and willingness to delegate scientific questions to experts. Children completed measures of IH, theory of mind, motivational framework, and intelligence, and neurophysiological measures indexing early (error-related negativity [ERN]) and later (error positivity [Pe]) error-monitoring processes related to cognitive control. Children's knowledge self-assessment correlated with question delegation, and older children showed greater IH than younger children. Greater IH was associated with higher intelligence but not with social cognition or motivational framework. ERN related to self-assessment, whereas Pe related to question delegation. Thus, children show separable epistemic and social components of IH that may differentially contribute to metacognition and learning.     

Using symbolic interactionism to analyze a specialized STEM high school teacher’s experience in curriculum reform

In this paper, we present a microanalysis of a specialized STEM (science, technology, engineering, and mathematics) high school teacher??s experience of self-initiated science inquiry curriculum reform. We examine the meanings of these two constructs: inquiry curriculum and curriculum change through the process lens of interactions, actions, and interpretations. Symbolic interactionism is the theoretical framework we used to frame our analysis of how this teacher, Darren Daley (a pseudonym) and various stakeholders purposefully and strategically engaged in ??face-work?? and act out lines of actions to advocate or oppose curriculum change. Symbols are used in this world of face-to-face encounters to communicate, imply, and assert, meanings through socially flexible and adjustable processes. We scrutinize how Daley (un)consciously engaged all of these to defend his decisions, actions, and outcomes and ??look?? to others as doing inquiry reform. The meanings of such work are not intrinsically driven or reactions to psychological and extraneous factors and forces, but emergent through interactions. The data collection methods include interviews with Daley, school administrators, students, and parents, lesson observations in Daley??s class, and gathering of school website pages, brochures, and curriculum materials. We represent data in narratives describing storied history, voices, interactions, anecdotal accounts from individuals?? experiences, and interpretations. The analysis and findings illuminate the nature of teacher agency??how it is reclaimed, sustained, reinforced, contested, exercised, and modified in more nuanced ways, hence offering an alternative lens to theorizing and empirically analyzing this construct.
