The effect of reciprocal teaching and programmed instruction on learning outcome in computer science education

Answers to the questions of which instructional methods are suitable for school, what instructional methods should be applied in teaching individual subjects and how instructional methods support the act of learning represent challenges to general education and education in individual subjects. This study focuses on the empirical examination of learning outcome with respect to two instructional methods: programmed instruction and reciprocal teaching. An SPF-2 × 2•2 design is used to control instructional method, time and class context. Learning outcome on search queries is assessed with reference to multi-choice test items. The empirical findings show that learning with programmed instruction performs better than reciprocal teaching.     

An evaluation of a professional learning network for computer science teachers

This paper describes and evaluates aspects of a professional development programme for existing CS teachers in secondary schools (PLAN C) which was designed to support teachers at a time of substantial curricular change. The paper’s particular focus is on the formation of a teacher professional development network across several hundred teachers and a wide geographical area. Evidence from a series of observations and teacher surveys over a two-year period is analysed with respect to the project’s programme theory in order to illustrate not only whether it worked as intended, by why. Results indicate that the PLAN C design has been successful in increasing teachers’ professional confidence and appears to have catalysed powerful change in attitudes to learning. Presentation of challenging pedagogical content knowledge and conceptual frameworks, high-quality teacher-led professional dialogue, along with the space for reflection and classroom trials, triggered examination of the teachers’ own current practices.     

Engaging pre-service science teachers to act as active designers of technology integration: A MAGDAIRE framework

This paper describes our efforts in developing the MAGDAIRE framework (abbreviated from Modeled Analysis, Guided Development, Articulated Implementation, and Reflected Evaluation) to transform pre-service science teachers’ roles in a teacher education course: moving pre-service teachers from the roles of passive users of technology, as they themselves learn technology integration, into active designers of technology. The results suggested that MAGDAIRE significantly improved the pre-service teachers’ technology competency levels. Moreover, MAGDAIRE facilitated the pre-service teachers’ critical reexamination of the affordances of technology for their teaching practices from the views of subject matter selection, motivation empowerment, information presentation, activity design, and pedagogy transition.

Information Communication Technology (ICT) integration in a science education unit for preservice science teachers; students' perceptions of their ICT skills, knowledge and pedagogy

There is an expectation that new science teachers will be able to effectively use a range of information communication technology (ICT) related resources inthe science classroom in order to enhance student learning. All school systems in Australia are in the process of providing teachers with ICT professional development and infrastructure. This paper outlines a range of initiatives designed to integrate ICT in a compulsory science education unit for students enrolled in a Graduate Diploma in Secondary Education. An action research model based on constructivist principles was used to evaluate the effectiveness of modelling, open-ended co-operative group activities and authentic assessment in enabling students to enhance their ICT skills, knowledge and pedagogical content knowledge in a science education context. Multiple sources of data were generated including a pre and post unit questionnaire that was analysed using Rasch modelling. The questionnaire determined students' perceptions of their preparedness to teach using ICT. The findings of this research suggest that some skills warranted greater attention in the unit, but students' pedagogical knowledge and knowledge and critique of ICT resources were enhanced over the duration of the unit.     

Democratizing computer science knowledge: transforming the face of computer science through public high school education

Despite the fact that computer science (CS) is the driver of technological innovations across all disciplines and aspects of our lives, including participatory media, high school CS too commonly fails to incorporate the perspectives and concerns of low-income students of color. This article describes a partnership program – Exploring Computer Science (ECS) – that directly counters this problem in our nation's second largest school district. With a mission of democratizing CS learning, we argue that despite the constraints of working within public schools, it is imperative to do so. We discuss the ECS program based on inquiry, culturally relevant curriculum, and equity-oriented pedagogy. We describe two ECS-affiliated projects that highlight the importance of authorship, purpose, and agency for student learning and engagement: DietSens using mobile technology to study community health, and a project in which students create video games about social issues. Our work offers a counter-narrative to those who have written off the possibilities of working within public schools and a debunking of the too widespread myth within our educational system that females and students of color are inherently uninterested in rigorous CS learning.     

Designing and implementing peer formative feedback within online learning environments

With increasing need to achieve appropriate balance between learning support and self-regulation within the context of online learning, formative feedback has been identified as a viable means to achieve meaningful engagement. Specifically, this study sought to establish how peer–peer formative feedback was facilitated in an online course and to what extent this engaged students in meaningful learning experiences. This case study entailed an in-depth investigation into the design and implementation of an online course in a New Zealand university. The studied course was part of a postgraduate programme in continuing (in-service) teacher education. The study adopted a case study methodology with a bias on qualitative techniques. Online observations, analysis of the archived course discourse and interviews were utilised as sources of data. The data from multiple sources were subsequently triangulated to corroborate the evidence. The findings indicate that peer formative feedback promoted active learners’ participation and meaningful engagement. The findings further showed that opportunities for dialogic peer formative feedback promoted learning support and self-regulation.     

Cognitive attainment in online learning environments: matching cognitive and technological presence

To know whether students' achievements are the result of online interaction and not just a consequence of individual differences themselves, it seems essential to link the cognitive results to the students' online behavior (technological presence). In technological presence, interaction is based on the degree in which the online student senses the availability of, and connectedness with, other students, the teacher, and the context. Cognitive presence as a part of the interaction process of teaching and learning reflects the level of accomplishment in online learning environments (cognitive attainment). The purpose of this article is to show some evidence of the mutual influence of the students' technological behaviors and the students' cognitive factors in online learning environments – including teacher and instructional design factors. Two thousand one-hundred thirty written computer-mediated communications from 88 participants in four prototypical online learning activities have been analyzed for this purpose. The analysis shows the influence of technological presence on the quality of learning results of the online knowledge construction process. The conclusions point out the importance of considering technological presence as a new and complementary type of presence as it provides relevant information for instructional and technological design.     

The Impending Revolution in Undergraduate Science Education

There is substantial evidence that scientific teaching in the sciences, i.e. teaching that employs instructional strategies that encourage undergraduates to become actively engaged in their own learning, can produce levels of understanding, retention and transfer of knowledge that are greater than those resulting from traditional lecture/lab classes. But widespread acceptance by university faculty of new pedagogies and curricular materials still lies in the future. In this essay we review recent literature that sheds light on the following questions:

• What has evidence from education research and the cognitive sciences told us about undergraduate instruction and student learning in the sciences?
• What role can undergraduate student research play in a science curriculum?
• What benefits does information technology have to offer?
• What changes are needed in institutions of higher learning to improve science teaching?

We conclude that widespread promotion and adoption of the elements of scientific teaching by university science departments could have profound effects in promoting a scientifically literate society and a reinvigorated research enterprise.     

OECD Work on Technology and Education: innovative learning environments as an integrating framework

This article presents in summary a selection of the work conducted by OECD in the field of technology and education, which has been an on-going focus of OECD work since the 1980s. Recently, much of this has been under the heading of ‘New Millennium Learners’, but it has also included the widening of student achievement surveys towards digital literacy; reviews of e-learning in higher education, surveys on Open Education Resources (OER); technology as a source of innovation; and analyses of the digital resources market and educational technology patents. The article proposes the more holistic focus on ‘learning environments’ through which to analyse the very diverse ways in which technology can be integrated into education and as a design framework. This is drawn from a report of the OECD Innovative Learning Environments (ILE) project to be published in 2013, itself based on 40 case studies from different countries and regions. It suggests that contemporary learning environments should be: i) Innovating the ‘pedagogical core’; ii) Engaging the ‘Design/Redesign Leadership Circle’; iii) Widening connections and capacity through partnerships; and iv) Promoting 21st century effectiveness (based on the principles derived from the 2010 ILE learning research review). The article then applies this framework to show how technology shapes learning environments in many different ways. The article questions over-reliance on individuals navigating successfully to access non-formal learning opportunities and rejects the argument that learning institutions should simply adapt more adequately to available technologies. Instead, technology should be fully exploited in well-designed learning environments.

The impact of scienceware and foundations on students' attitudes towards science and science classes

In this paper, we describe changes in students' ideas about science classes, attitudes about science, and motivations for studying science, in a classroom designed to support projectbased science learing. Using a survey designed to provide a measure of students' attitudes towards science classes and science, we have compared students enrolled in a traditional high school biology course, with students enrolled in an integrated, project-based science course called Foundations I. Survey responses were analyzed to look at differences between and within two groups of students over the course of one school year. In general, the results of this study suggest that providing students with opportunities to collect and analyze their own data in science classes results in a change in students' ideas about science classrooms. Foundations I students' increased tendency to agree with statements about using information, drawing conclusions, and thinking about problems, implies a change in their understanding of what it means to do science in school. These students, in contrast to students in the traditional Biology course, no longer describe their science experience as one of memorization, textbook reading, and test taking. Instead they see science class as a place in which they can collect data, draw conclusions, and formulate and solve problems.

Evaluating the effects of analogy enriched text on the learning of science: The importance of learning indexes

Research has shown that differences in the prior knowledge of the participants and in the learning indexes adopted can explain why some studies show positive learning effects of analogy enriched text while others do not. In the present studies, these two factors were combined into one through the construction of a learning index that measured incremental positive changes in the participants' prior knowledge after reading an analogy enriched or no analogy text. A second learning index was also used to evaluate whether the participants created well-formed conceptual models after reading the science text. These learning indexes were used in two studies in which the effects of analogy enriched versus no analogy text were compared on the learning of the scientific explanations of the day/night cycle and of the seasons. The participants were 3rd and 5th graders in the first study and 6th graders and college students in the other. Although only few of the participants learned the correct scientific explanation, those who read the analogy enriched text produced more incremental positive changes in their pretest explanations at posttest and delayed test and created more well-formed conceptual models close to the scientific one than those who read the no analogy text. They also recalled more information and created fewer invalid inferences in their recalls. The results indicate that analogies can be used without reservation to facilitate the learning of science and have broader implications about how to evaluate the learning of science in general.     

Not a stale metaphor: the continued relevance of pedagogical content knowledge for science research and education

Recently, theorists have raised concerns that pedagogical content knowledge (PCK) has become “a stale metaphor” that disregards diversity and equity, offers little to help teachers address students’ misconceptions, and portrays knowledge as “in the head” versus in practice. We refute these notions using grounded theory to specify ways one 7th-grade science teacher enacted PCK to advance student learning. With the definition of PCK as knowledge at the intersection of content and teaching, we utilised a framework for science PCK to explore instructional decision-making. Interviews conducted over three years revealed specific ways the teacher enacted PCK by designing and delivering instruction built on each of the seven conceptual science PCK components. The teacher enacted PCK to plan and deliver instruction that was responsive, adaptive, and considerate of changing needs of students and the changing classroom landscape. She infused PCK into instructional decision-making, instructional interactions, and mentoring of a student teacher, modelling the translation of educational theory into practice and habits of mind necessary for expert teaching. This enactment actively refutes Settlage’s critiques, and depicts PCK as a vibrant and effective stance for teaching that enhances learning.
