Four Educators in Plato's Theaetetus

Scholars who have taken interest in Theaetetus' educational theme argue that Plato contrasts an inferior, even dangerous, sophistic education to a superior, philosophical, Socratic education. I explore the contrasting exhortations, methods, ideals and epistemological foundations of Socratic and Protagorean education and suggest that Socrates' treatment of Protagoras as educator is far less dismissive than others claim. Indeed, Plato, in Theaetetus, offers a qualified defence of both Socrates and Protagoras. Socrates and Protagoras each dwell in the middle ground between the extremes presented in the dialogue's digression, which contrasts the life of the philosopher and the life of the courtroom orator. Both Socrates and Protagoras demonstrate a serious engagement with both politics and philosophy. Theodorus presents an educational option in which theory is divorced from politics while an ignoble sophistic education is presented as political but divorced from theory. Protagorean education, in Theaetetus, emerges as superior to a base sophistic education, though it remains inferior to Socratic education.     

Bounding,An Accessible Method for Estimating Principal Causal Effects,Examined and Explained

Estimating treatment effects for subgroups defined by posttreatment behavior (i.e., estimating causal effects in a principal stratification framework) can be technically challenging and heavily reliant on strong assumptions. We investigate an alternative path: using bounds to identify ranges of possible effects that are consistent with the data. This simple approach relies on fewer assumptions and yet can result in policy-relevant findings. As we show, even moderately predictive covariates can be used to substantially tighten bounds in a straightforward manner. Via simulation, we demonstrate which types of covariates are maximally beneficial. We conclude with an analysis of a multisite experimental study of Early College High Schools. When examining the program's impact on students completing the ninth grade “on-track” for college, we find little impact for ECHS students who would otherwise attend a high-quality high school, but substantial effects for those who would not. This suggests a potential benefit in expanding these programs in areas primarily served by lower quality schools.     

SOCIETAL ISSUES AND THEIR IMPORTANCE FOR CONTEMPORARY SCIENCE EDUCATION��A PEDAGOGICAL JUSTIFICATION AND THE STATE-OF-THE-ART IN ISRAEL, GERMANY, AND THE USA

One common theme underlying recent reports on science education is that the content of school science and its related pedagogical approaches are not aligned with the interests and needs of both society and the majority of the students. Most students do not find their science classes interesting and motivating. These claims are especially valid regarding those students who, in the future, will probably not embark on a career in science or engineering but will need science and technology personally and functionally as literate citizens. One key problem seems to be that few science programs around the world teach how science is linked to those issues that are relevant to students’ life, environment, and role as a citizen. As a result, many students are unable to participate in societal discussions about science and its related technological applications. This paper discusses the need to incorporate socioscientific ideas into the science curricula more thoroughly. This recommendation is supported by a theoretical rationale from various sources leading to a reflection about common practices in science education in three countries: Israel, Germany, and the USA. The state-of-the-art, potentials, and barriers of effective implementation are discussed.     

Clarifying mastery-avoidance goals in high school: Distinguishing between intrapersonal and task-based standards of competence

The definition, measurement, prevalence, and relations of mastery-avoidance goals with engagement outcomes are still under debate. Study 1 (n = 256) aimed to investigate these issues among junior high and high school students in two domains. Findings indicated that students distinguished between the three commonly assessed achievement goals and mastery-avoidance goals. Moreover, students distinguished between the two standards conceived to underlie mastery-avoidance goals—task-mastery and intrapersonal competence. However, the task-mastery items failed to show reliability. Study 2 (n = 118) aimed to replicate the results of Study 1 as well as to investigate the associations of mastery-avoidance goals with self-regulation strategies and affect in school. Intrapersonal mastery-avoidance goals were positively related to adaptive strategies and negatively with maladaptive strategies. Moreover, when combined with mastery-approach goals, intrapersonal mastery-avoidance goals enhanced students’ reports of adaptive affect in school. The implications of these findings to theory, method, and future directions are discussed.     

Clarifying Metacognition, Self-Regulation, and Self-Regulated Learning: What’s the Purpose?

In this commentary on the special issue, I join the authors in searching for a conceptual framework that would clarify the concepts of metacognition, self-regulation, and self-regulated learning. Building on the insights of the different articles, I suggest that metacognition, self-regulation, and self-regulated learning should be considered as subtypes of the general, abstract, phenomenon of self-regulated action. I continue by questioning the benefit of seeking boundaries between these three concepts. Instead, I propose to search for dimensions along which types of self-regulated action vary. I, then, introduce the notion of a “multidimensional conceptual space of self-regulated action” as a conceptual tool that allows for diversity of conceptions of self-regulated action while maintaining conceptual clarity. I conclude by highlighting the central role of purpose of engagement in self-regulated action and by noting its potential for guiding the search for meaningful dimensions on which to typify self-regulation.     

The Professional Development of High School Chemistry Coordinators

The implementation of new content and pedagogical standards in science education necessitates intensive, long-term professional development of science teachers. In this paper, we describe the rationale and structure of a comprehensive and intensive professional development program of school-based leaders, namely school chemistry coordinators. The year-long program was designed so that the chemistry teachers who enrolled in the program were able to develop in three interrelated aspects: content knowledge, pedagogical content knowledge, and leadership ability. Several strategies for the development of these aspects were adopted from Loucks-Horsley, Hewson, Love, & Stiles (1998). The evaluation of the program focused on the changes that participating teachers underwent regarding their personal beliefs and their functioning as school chemistry coordinators in their schools.     

The Effect of Achievement Goals: Does Level of Perceived Academic Competence Make a Difference?

Researchers using a goal orientation framework have hypothesized that learning goals are associated with adaptive patterns of behavior, regardless of the level of perceived ability. In contrast, perceived ability is hypothesized to moderate the relation between performance goals and patterns of adaptive or maladaptive behavior. We examined this hypothesis in two samples of seventh grade middle school students, focusing on the math domain in one sample and on the English domain in the other. Using two different statistical methods, median split and multiple regression, we found only little support for the role of perceived competence as a moderator between performance goals and patterns of behavior. Contrary to what has been suggested, we found some evidence that perceived competence moderated the relation between learning goals and behavior. Implications of these findings for recent efforts to use goal theory to reform classrooms and schools are discussed.
