Teaching Students to become Critical Television Viewers

The late 1970s saw a growth of interest in the United States in preparing students to become active rather than passive television viewers and in providing materials to teachers to use television constructively in the classroom. This article provides an overview of these activities and describes in detail the development of critical television viewing skills materials for secondary students.     

Elementary science education library resources in graduate and undergraduate teacher education programs of new England

The purpose of this study was to compare elementary science education library resources available in graduate and undergraduate teacher education institutions in New England. A 31-item survey was sent to teacher education institutions certified to prepare elementary teachers. The survey had four components: (1) services (i.e., ERIC, computer search, etc.), (2) journal holdings/science (i.e., Science and Children, Science Education, etc.), and nonscience (i.e., Reading Teacher, Instructor, etc.), (3) resources available (i.e., elementary science textbooks, audio-visual materials, computer software, etc.), and (4) an open-ended question about what major resources were needed to help prepare preservice students to teach science. There was a 72% return rate from the 87 institutions. Data were analyzed by the FREQUENCIES and ONEWAY subprograms of SPSSX. Less than 34% of the non-graduate libraries had ERIC microfiche available, Dissertation Abstracts, and computer search capabilities services. There was significant difference between graduate and nongraduate institutions journal holdings for science education journals and indexes. The surveyed libraries had more elementary science textbooks published prior to 1980 than those published after 1980 and were severely lacking in computer software.     

Interview Experiences and Diversity Concerns of Counselor Education Faculty From Underrepresented Groups

The authors used transcendental phenomenology to explore the campus interview experiences and diversity concerns of counselor education faculty from underrepresented populations. Six themes were identified: issues of integrity, disappointment in the counseling profession, importance of authenticity, intersectionality of major identity markers, competence, and supportive experiences. Findings suggest that culturally competent search committees should be aware of biases and policies promoting institutional and systemic discrimination.     

Do Elementary Science Methods Textbooks Facilitate the Understanding of Magnet Concepts?

The study of magnets is a common physical science topic for elementary students. This study examined elementary science methods textbooks to determine how magnet concepts were presented. Each methods textbook's section relating to magnets was read. Particular attention was paid to the organization, sequence of concepts, potential misconceptions, and types of investigations included. A previously validated magnet concept list was used. A detailed analysis of 11 elementary science methods textbooks found great variation in the magnet concepts presented, general omission of ceramic magnets, frequent misconceptions about poles, and limited investigations that address both attraction and repulsion.     

Effect of ice hockey stick stiffness on performance

Hockey sticks have undergone a dramatic transformation from wood to aluminum to composite in just over the past 20 years. With the introduction of different materials, there has been increasing interest in how the material properties affect shot speed. This study examined the effects of stick stiffness from measured swing motion on puck speed. Stick evaluation involved a six amateur player study, quasi-static stiffness measurement, video motion analysis, and numerical simulation. The effect of stiffness on puck speed was observed to depend on shot type. For shots involving large stick loading, as occurs with a slap shot, puck speed decreased as stick stiffness increased. The trend was consistent with a constant force player model. For shots involving low stick loading, as occurs with a wrist shot, puck speed increased as stick stiffness increased. The trend was consistent with a constant displacement player model. Finite element simulation of the slap shot agreed generally with the results of the player study and was used to find an optimal loading distance (distance that the stick contacts the ice prior to the puck) to be 24 cm.     

Effect of order of exercise on performance during a complex training session in rugby players

In this study, we examined the acute effects of manipulating exercise order when combining countermovement jumps and loaded parallel squats in a complex training session, and the acute effects of countermovement jumps and loaded parallel squats on sprinting performance. Eight rugby players participated in five trials, including two that involved performing loaded parallel squats followed by countermovement jumps or vice versa in a randomized cross-over design. Peak rate of force development and peak force were measured during countermovement jumps and loaded parallel squats. Peak power, jump height, and duration of amortization phase were also determined during the countermovement jumps. Peak force during squatting was significantly greater in both cross-over treatments (loaded parallel squats-countermovement jumps and countermovement jumps-loaded parallel squats) compared with the control (P 相似文献
