Bumble Boosters: Students Doing Real Science

Bumble Boosters was a lottery grant funded cooperative project between the University of Nebraska – Lincoln Department of Entomology, the Lincoln Public Schools Science Focus Program, and the Lincoln Folsom Children's Zoo. The primary education goal of the project was to create a community of learners to conduct authentic research on bumble bees in Nebraska. Participants were actively engaged in collecting bumble bees and placing nesting domiciles. Internet technology was employed to facilitate networking between project participants. Systematic evaluation was conducted during and after the project.     

Determinants of Primary School Choice in Malaysia: School Proximity and Ethnicity-Related Reasons

The study examined determinants of primary school choice among parents in Malaysia, and the decision maker and social influences in the school choice. It draws on qualitative data from semi-structured interviews with 43 middle-class parents from three ethnic groups (Chinese, Malay, and Indigenous). Results showed that school proximity and ethnicity-related reasons are leading factors influencing parental school choice. Medium of instruction, school academic reputation, and feeder to a preferred secondary school appear to be separate reasons but act as a proxy to ethnicity as the primary factor determining the choice of Chinese- or Malay-medium primary school by parents. The results also showed that mothers are more likely to make school choice decisions than fathers, but the reasons for school choice are similar. The primary social influences on their school choice come from friends and education personnel in preschools and schools. The Indigenous parents tend to be more subject to social pressure in making school choices than the Chinese and Malay parents, who mostly enroll their children in Chinese- and Malay-medium primary schools, respectively. However, these findings on school choice and ethnic segregation are limited to this sample and constrained by the socio-political context of the education system.     

Science Teachers’ Perceptions: Similarities and Differences in the U.S., England,Singapore and Japan

The prospect of using internationally generated comparative data, augmented with practice patterns, to provide useful information from which countries can learn from each other, is gaining acceptance from the increasing popularity of such an approach (Stigler and Hiebert, 1999). Using the survey data from TIMSS we examine the beliefs of teachers in the U.S., England, Singapore and Japan, and find little national variation in many teachers’ perceptions of core practices in science teaching, indicating that science teachers the world over share the same common core practices. However, there is one key difference among their practices, which signals a departure in the way teachers in Japan and Singapore operate vis‐à‐vis those in the U.S. and England. This key difference is attributed to cultural differences in the U.S. and England, when compared to Japan and Singapore.     

Balancing the Media

This paper outlines a ‘conversational framework’ for describing the essential elements of the learning process. The framework is used to elaborate the kinds of learning activities students need to carry out in order to arrive at a conceptual understanding of the topic they are studying. The framework is then applied to contrasting learning media: print, video, computer‐based tutorial and teacher‐student discussion, to determine which learning activities each is capable of supporting. These combinations of ‘multiple media’ are then compared with the new ‘multi‐media’ systems for their likely pedagogical benefits.     

Community support programme: support for Chinese trans* students experiencing genderism

Abstract

Previous research on school experiences has often focused on lesbian and gay students. Far fewer studies have examined trans* students’ experiences, especially with respect to community support. And none of this work has addressed relevant issues in an East Asian Chinese cultural context, where transgender equality has been a hotly debated issue in recent years, and prejudice towards members of this ‘invisible’ population still persists. This paper highlights the school experiences of trans* students based on a literature review of international, regional and Hong Kong publications. A case study analysis of one Hong Kong community support programme is used as an example to highlight the important role that this kind of work can play in filling a gap left by the formal education sector. Findings suggest that, given the influence of genderism and deficiencies of in school environments, community support services provided by non-government organisations can play a significant role not only in raising public awareness, but also in filling education and service gaps for sexual and gender minority students.     

Computers and the emancipation of students: giving control to the learner

The paper considers two basic models of the teaching-learning process, described as the didactic and the communication model. These are applied to Computer Assisted Learning (CAL) in order to demonstrate that CAL has generally embodied a didactic model of teaching and learning. This imposes an unnecessary restriction on the student's freedom to choose their (Note 1) learning style, and the paper discusses how it is possible for CAL to support a less didactic model and to give more control to the student.     

Savings test for associations between neutral stimuli

Three experiments showed a savings procedure to be an effective and sensitive alternative to sensory preconditioning procedures as a measure of associations among neutral stimuli. Experiment 1 showed that within-compound associations developed more rapidly in reinforced appetitive serial compound conditioning when nonreinforced preexposure to the serial compound was given than when separate element or no preexposure was given. Experiment 2 showed the savings effect to be highly stimulus specific. Experiment 3 examined the facilitation of serial compound conditioning after either simultaneous or serial nonreinforced preexposure to the elements of the compound. The results of that experiment were consistent with those of analogous sensory preconditioning experiments. When preexposure involved only the two elements of the subsequently reinforced compound, serial preexposure produced more savings than simultaneous preexposure. But when preexposure involved a three-stimulus procedure like that used by Rescorla (1980b), simultaneous preexposure resulted in more savings. Advantages of the savings procedure over sensory preconditioning as a measure of association among neutral stimuli are discussed.     

Feature extinction enhances transfer of occasion setting

In three experiments, transfer effects in appetitive serial feature-positive discrimination procedures (X→A+,A?) were examined with rat subjects. Nonreinforced presentations of the feature (X) alone had little or no effect on that cue’s ability to modulate responding to the target cue with which it had originally been trained (A) but enhanced its ability to modulate responding to another cue (B), which had been the target within another serial feature-positive discrimination (Y→B+,B?). These effects were observed when the nonreinforcedX presentations occurred either concurrently withX→A+,A? training or afterward. Regardless of whether or not nonreinforcedX presentations were administered,X did not modulate responding evoked by a cue that had not been trained within a serial feature-positive discrimination. These data help resolve conflicts in published reports of transfer or its absence in this conditioning situation, and shed light on the nature of the modulatory or occasion-setting powers of feature cues in serial feature-positive discrimination learning.
