Does STES‐Oriented Science Education Promote 10th‐Grade Students’ Decision‐Making Capability?

Today’s society is continuously coping with sustainability‐related complex issues in the Science‐Technology‐Environment‐Society (STES) interfaces. In those contexts, the need and relevance of the development of students’ higher‐order cognitive skills (HOCS) such as question‐asking, critical‐thinking, problem‐solving and decision‐making capabilities within science teaching have been argued by several science educators for decades. Three main objectives guided this study: (1) to establish “base lines” for HOCS capabilities of 10th grade students (n = 264) in the Israeli educational system; (2) to delineate within this population, two different groups with respect to their decision‐making capability, science‐oriented (n = 142) and non‐science (n = 122) students, Groups A and B, respectively; and (3) to assess the pre‐post development/change of students’ decision‐making capabilities via STES‐oriented HOCS‐promoting curricular modules entitled Science, Technology and Environment in Modern Society (STEMS). A specially developed and validated decision‐making questionnaire was used for obtaining a research‐based response to the guiding research questions. Our findings suggest that a long‐term persistent application of purposed decision‐making, promoting teaching strategies, is needed in order to succeed in affecting, positively, high‐school students’ decision‐making ability. The need for science teachers’ involvement in the development of their students’ HOCS capabilities is thus apparent.     

Improving Risk Education in Grades 6–12: A Needs Assessment of Michigan,Ohio, and Wisconsin Science Teachers

Abstract

If formal educators are to play a role in preparing future citizens for making decisions about health and environmental risks, then they must be willing and able to incorporate risk education. This article presents 10 goals for risk education. It also describes current risk education practices, future interests, and perceived barriers to risk education of Michigan, Ohio, and Wisconsin Grades 6–12 science teachers. Data were collected through a mail questionnaire (1,336 surveys were returned, adjusted return rate = 80%) and in-depth telephone interviews (completed with 45 teachers, return rate = 90%). Many teachers had covered some aspect of risk education and were interested in enhancing their efforts. Results also suggest that teachers need to be made aware of risk education resources and provided with training, particularly regarding psychological influences on risk decisions.     

REPORT OF BIBLICAL INSTRUCTORS CONFERENCE*

This article examines the psychoanalytic concepts of object-relations theorist Christopher Bollas, applying them to a view of the Bible as “transformational object.” Emphasizing the connection between psychological process and religious experience, this article suggests that each person's innate ability to choose and use objects is a key factor in their ability to appropriate the Bible for constructive use. By offering religious objects with psychological awareness, religious educators may come to appreciate that silence, empathy, and open-ended lesson plans are important incubators of transformation; and that aggression has a potentially positive role in the healthy development of worship communities.     

Applying Tablet‐Based Performance Support Application for Technicians’ Training at the Israeli Air Force: A Case Study

Performance support systems are mechanisms enabling users) productivity while reducing training expenses as support is being delivered in real time, often eliminating the need for costly pre‐performance training. Mobile technologies have created new opportunities for improved performance support systems, especially for tasks performed outside the offi ce. This article describes the fi rst mobile learning and performance support initiative taken by the Israeli Air Force. The project included the development and eff ectiveness pilot study of a learning and performance support application delivered via tablet to helicopter engine technicians. The application provided support videos and illustrations of maintenance routines, thereby enabling learning and practicing at the same time. Pilot study results show high performance levels of application users compared to those applying traditional methods. Results also show that self‐effi cacy levels were not aff ected by the successful performance achieved when using the mobile performance support application. Plans to expand mobile support use are also described.
