Interest in biology. Part I: A multidimensional construct

Interest in a school subject (e.g., biology) is conceptualized in terms of three components: topics, activities, and motives, each of which has several dimensions. In this study, seven instruments were developed and administered to grade-10 biology students in Israel. Factor analysis provided support for the conceptualization which underlies the development of the instruments. Topic dimensions included biochemical processes, nonhuman organisms, human biology, personal hygiene, and practical applications; the activity dimensions were experiential learning, reception learning, writing/summarizing and group discussion; motives included environmental issues, moral issues, examination success, personal independence, problem solving, and four career dimensions (research, high-status professions, lower-status careers, “woodsy-birdsy” careers). In an analysis described in Part II of this paper, the students were classified into four groups on the basis of their grade-11 subject enrollment intentions: H (high-level biology), L (low-level biology), P (physical science), and N (no science). Zero-order and multiple correlations were found between interest and other variables and membership/nonmembership of the four groups. Students in Group H were characterized by higher achievement in year-10 biology, higher levels of enjoyment of biology, career orientations towards research or high-status biology-based professions, greater interest in various biology topics, especially reproduction/cell division/genetics, and a greater tendency to regard the Bagrut (grade-12) examination as interesting. Students in Group N displayed lower levels of interest in various topics (especially the microscope, plants, and reproduction), were less motivated to solve problems, had poorer grades in biology (and chemistry), were less likely to perceive biology as useful, were less likely to regard the Bagrut examination as fair, and were less likely to be interested in social modes of learning. There were few associations between interest variables and membership in Groups L or P.     

Curriculum Materials and Resources in Teacher Education Programmes

The authors report on a survey carried out of the present utilisation of curriculum materials and resources in teacher education in the State of Israel. A number of felt needs are identified and proposals for action are put forward.     

Reflections on soccer,sovereignty and the state of exception

In this paper, I examine soccer, sovereignty and the state of exception. The paper is a pedagogical tool for undergraduate students in order for them to learn about sovereignty and the ‘state of exception’ through soccer, the world’s most popular sport. I begin by examining differing conceptions of sovereignty and the state of exception. I then highlight the fate of soccer under various states of exception. I focus on Pinochet’s Chile, but also provide examples from the Argentinean military junta, Nazi Germany and El-Sisi’s Egypt. I then reflect about soccer, sovereignty, and the state of exception in relation to Fédération Internationale de Football Association. I offer concluding remarks about soccer and states of exception. I argue that states of exception are in theory opportunities for change because they expose the naked aggression of states, but in practice they represent a danger for soccer players, fans and democracy.     

Israeli Students’ Conceptions of Science and Views about the Scientific Enterprise

Abstract

Israeli students’ conceptions of the nature of science and views about the scientific enterprise were studied within the framework of the Second International Science Study (SISS). Representative samples of 10, 14 and 17year‐old student, about 2000 in each, responded to background questionnaires and a battery of tests and scales. The Science Understanding Measure, a 20 item, multiple choice instrument provided data on understanding the nature of science by 14 and 17 year‐olds. An Attitude toward Science Scale provided data on the views of 10, 14 and 17 year‐olds on the importance of science to society and to individuals, the usefulness of science in everyday life and on harmful aspects of science. A comparison was made between the view of Israeli, British and USA students. The relationships of the conceptions and views of 17 year‐olds with personal, home and school variables as well as with achievement in science, intentions for further learning and career aspirations were explored as well. Based on the results and conclusions some recommendations are offered on how to enhance the understanding of science and promote more positive attitudes towards the scientific enterprise     

Role-based Association of Verbs,Actions, and Sentiments with Entities in Political Discourse

A crucial challenge in measuring how text represents an entity is the need to associate each representative expression with a relevant entity to generate meaningful results. Common solutions to this problem are usually based on proximity methods that require a large corpus to reach reasonable levels of accuracy. We show how such methods for the association between an entity and a representation yield a high percentage of false positives at the expression level and low validity at the document level. We introduce a solution that combines syntactic parsing, semantic role labeling logic, and a machine learning approach—the role-based association method. To test our method, we compared it with prevalent methods of association on the news coverage of two entities of interest—the State of Israel and the Palestinian Authority. We found that the role-based association method is more accurate at the expression and the document levels.     

Generality of US preexposure effects: Transfer from food to shock or shock to food with and without the same response requirements

A series of four experiments, employing mice, investigated the generality of the learned helplessness phenomenon. The first two experiments used preexposure to aversive stimuli (shock), while the other two used preexposure to appetitive stimuli (food). In all of the studies, subjects were preexposed to contingent, noncontingent, or no stimuli (except for Experiment 2) in a Skinner box. During the test, animals preexposed to shock were tested with food, and those preexposed to food were tested with shock. The test was conducted in a similar situation, a Skinner box (Experiments 1, 3), or a different situation—a runway (Experiments 2, 4). Performance decrements were evident when subjects that were preexposed to a noncontingent stimulus were compared with subjects preexposed to contingent stimuli. The differences between the contingent and the noncontingent groups were significant, as were the differences between the contingent and the nonpreexposed groups (except for Experiment 1). The effects cut across the different types of stimuli, situations, and response requirements of the preexposure and test phases.     

High school preparation for college biology in Israel

The study reports the results of a questionnaire on the opinions of biology, medical and agricultural students regarding the nature of the contribution of high school biology to their study of biology in the university. It was found that most students value the contribution of high school biology to their learning, understanding and retention of new material. Students who specialized in high school biology and who studied an inquiry-oriented program in high school had definite advantages over the others. High school experiences were found to influence achievement in college biology to the extent to which the university courses were based upon prior knowledge.     

Justifying the selection of answers in multiple choice items

Although multiple choice tests, as commonly used, can be rightly criticized, their structure, when wisely used, makes them an excellent diagnostic tool for identifying students’ conceptions, including misconceptions. This paper offers a number of useful guidelines regarding the analysis of multiple choice items. A special reference is made to the use of the justifications that students provide for their choices. Examples of the procedures, which may be used in analysing justifications and the kinds of diagnostic information that may be obtained, are provided.     

High school students’ difficulties in understanding osmosis

Preconceptions and misconceptions of 500 secondary students in years 9‐12 regarding osmosis were studied through the use of five different kinds of instruments: prior learning inventory, self‐report knowledge inventory, true/false test, definitions and clinical interviews. Some of the major findings were: (1) The most frequent explanation offered to osmosis is ‘a desire or drive towards equalizing concentrations’. (2) Hardly any student uses the concept ‘water concentration’. (3) Most students fail to realize that in dynamic equilibrium water molecules keep moving. (4) Students have special difficulty in understanding osmotic relations in plants. (5) Many students have difficulty in grasping solute‐solvent and concentration‐quantity relations. (6) Students often perform laboratory experiments without really understanding the underlying principles. Practical and theoretical implications are discussed.
