Differential response to structure of advance organizers in science instruction

In an experiment designed to investigate individual differences in learning from written materials preceded by advance organizers, 89 fourth-grade subjects were randomly assigned to treatment conditions in which programmed material on insects was preceded by one of three introductory passages containing: (1) higher level generalizations and specific examples; (2) higher level generalizations without examples; or (3) a control passage. Membership in treatment groups was determined by random assignment. Criterion performances were immediate and delayed posttest performance and errors during instruction. Analysis of variance results of treatment effects showed that the three treatments were about equally effective in terms of promoting retention and program errors. Simple regression analysis of Aptitude × Treatment interactions disclosed that Otis-Lennon IQ scores interacted significantly with instructional treatments for program errors showing a negative relationship between IQ scores and the degree of structure provided by the advance organizers.

Science teaching in science education

Reading the interesting article Discerning selective traditions in science education by Per Sund, which is published in this issue of CSSE, allows us to open the discussion on procedures for teaching science today. Clearly there is overlap between the teaching of science and other areas of knowledge. However, we must constantly develop new methods to teach and differentiate between science education and teaching science in response to the changing needs of our students, and we must analyze what role teachers and teacher educators play in both. We must continually examine the methods and concepts involved in developing pedagogical content knowledge in science teachers. Otherwise, the possibility that these routines, based on subjective traditions, prevent emerging processes of educational innovation. Modern science is an enormous field of knowledge in its own right, which is made more expansive when examined within the context of its place in society. We propose the need to design educative interactions around situations that involve science and society. Science education must provide students with all four dimensions of the cognitive process: factual knowledge, conceptual knowledge, procedural knowledge, and metacognitive knowledge. We can observe in classrooms at all levels of education that students understand the concepts better when they have the opportunity to apply the scientific knowledge in a personally relevant way. When students find value in practical exercises and they are provided opportunities to reinterpret their experiences, greater learning gains are achieved. In this sense, a key aspect of educational innovation is the change in teaching methodology. We need new tools to respond to new problems. A shift in teacher education is needed to realize the rewards of situating science questions in a societal context and opening classroom doors to active methodologies in science education to promote meaningful learning through meaningful teaching.

Evaluating student perceptions of learning processes and intended learning outcomes under inquiry approaches

Inquiry-based learning (IBL) is promoted as a teaching approach that can enhance student learning outcomes. IBL can be categorised according to scale (e.g. tasks, course/module/paper, degree), mode (structured, guided, open) and framing (information or discovery-oriented). Our research used a survey instrument to determine how student perceptions of learning processes and intended learning outcomes (ILOs) varied in response to courses with different modes and framing of IBL. The survey was completed by 940 students in 15 IBL courses across a range of disciplines and levels. All types of IBL courses were well rated by students for encouraging learning processes and ILOs congruent with a well-designed inquiry experience. Regarding modes of IBL, there was a clear hierarchy from open (most highly rated) to guided and then structured inquiry. For the framing of IBL, courses using discovery-oriented IBL were more highly rated than information-oriented IBL. Overall, the most highly rated course design was open, discovery-oriented IBL, but other types of IBL remained important in terms of developing research and inquiry skills. To determine whether all types of IBL courses are promoting enhanced ILOs compared to more traditionally taught courses, a comparative study should be undertaken.

科学教学中的"探究"释义

根据教学论,科学教学中的“探究”可有三层含义:作为教学目标,指学生应掌握的科学探究技能,要理解的科学探究特性;作为教学原则,指激发学生积极探究未知、主动建构意义的基本教学要求;作为教学方法,指学生在教师指导下所采用的类似科学探究过程的学习方式或程序。

The effects of computer-supported self-regulation in science inquiry on learning outcomes,learning processes,and self-efficacy

Recently, researchers have demonstrated the benefits of technology-enhanced science inquiry activities. To improve students’ self-regulation and assist them in controlling their own learning pace through inquiry activities, in this study, a self-regulated science inquiry approach was developed to assist them in organizing information from their real-world exploration. A quasi-experimental design was conducted in an elementary school natural science course to evaluate the students’ performance using the proposed learning approach. One class assigned as the treatment group learned with the self-regulated science inquiry approach, while the other class assigned as the control group learned with the conventional science inquiry approach. The students’ learning achievement, tendency of information help seeking, tendency of self-regulation, and self-efficacy were evaluated. The results of the study revealed that the self-regulated science inquiry approach improved the students’ learning achievement, especially for those students with higher self-regulation. In addition, the students who conducted inquiry with the self-regulated learning strategy increased their tendency of information help seeking, self-efficacy, and several aspects of self-regulation, including time management, help seeking, and self-evaluation. Accordingly, this study demonstrated the effectiveness of the self-regulated learning strategy, an approach with high learner control, in terms of improving students’ learning achievement and their self-regulation.     

Student intrinsic motivation,science teaching practices and student learning

Conclusion This paper has been concerned with the application of basic understandings about intrinsic motivation and curiosity behaviour to the teaching of science, and in particular senior high school biology. The important role of student knowledge in the generation, maintenance and resolution of cognitive conflict is congruent with the renewed interest in studying students' everyday knowledge of curriculum content. However the study of classroom teaching processes in terms of their facilitation of intrinsic motivation is not common. Yet the data collected in this study demonstrates the importance of closely examining the implementation of courses such as the Web of Life, if the arousal of intrinsic motivation is an intended student outcome. Both interview and observational data indicated that the teaching styles adopted by teachers in this study were not likely to engender curiosity amongst students. Perhaps this should be expected. The use of a wide range of reference materials to investigate problems that arise in the classroom, the encouragement of students to do additional work on a topic if they are particularly interested, and a willingness on the part of the teacher to allow students sufficient time to formulate their own solutions to problems are classroom processes which necessitate a greater flexibility in curriculum presentation than can be often tolerated by teacher and school management. Such processes may be incompatible with organisational properties of the school and the pressures often placed upon students to perform to a high standard on rigidly defined examinations.
