Computer‐Assisted Instruction and Conceptual Change

Abstract

In this study, the question was addressed which instructional conditions are required to teach students how they themselves can initiate and perform learning activities aimed at conceptual change. The CONTACT‐2 strategy (a computer‐assisted instructional strategy for promoting conceptual change in the domain of basic physical geography) served as starting point for the design of several training procedures aimed at enhancing self‐regulated learning. With the first experimental condition, strategic support was gradually withdrawn ('faded') within each instructional step, while, with the second experimental condition, the number of steps was reduced as the training continued. The original CONTACT‐2 condition served as control condition. Subjects were 65 fifth‐ and sixth‐graders (primary education). Dependent variables concerned students’ abilities to initiate and perform learning activities aimed at conceptual change, the quality of their conceptions, and their learning performance. Results suggested that ‘fading’ can be a fruitful instructional approach to foster self‐regulated learning aimed at conceptual change, provided that the ‘fading’ procedure is tuned to the students’ actual level of self‐regulated learning: external control should not be withdrawn until students are able (and prepared) to initiate and perform the learning activities being required. When these conditions are met, designing effective training procedures aimed at ‘learning for conceptual change’ seems possible.     

Effectiveness of Conceptual Change Text-oriented Instruction on Students’ Understanding of Energy in Chemical Reactions

The aim of this study is to compare the effectiveness of conceptual change text instruction (CCT) in the context of energy in chemical reactions. The subjects of the study were 60, 10th grade students at a high school, who were in two different classes and taught by the same teacher. One of the classes was randomly selected as the experimental group in which CCT instruction was applied, and the other as the control group in which traditional teaching method was used. The data were obtained through the use of Energy Concept Test (ECT), the Attitude Scale towards Chemistry (ASC) and Science Process Skill Test (SPST). In order to find out the effect of the conceptual change text on students’ learning of energy concept, independent sample t-tests, ANCOVA (analysis of covariance) and ANOVA (analysis of variance) were used. Results revealed that there was a statistically significant mean difference between the experimental and control group in terms of students’ ECT total mean scores; however, there was no statistically significant difference between the experimental and control group in terms of students’ attitude towards chemistry. These findings suggest that conceptual change text instruction enhances the understanding and achievement.     

Can we Speak of Alternative Frameworks and Conceptual Change in Mechanics?

This paper discusses the various conflicting trends in mechanics education that have appeared over the past two decades, and proposes the theory of schemata as a means to resolve the conflict that exists within the literature. The conflict has two causes: the prevailing relativism that exists within science education, and the mistaken view that student alternative ideas are concepts that are well defined. We argue that student alternative ideas can be best understood in terms of schema theory, and that schema theory can offer support to the Vygotskian idea of the teacher facilitating the construction of the Newtonian system within the students zone of proximal development. Within the context of schema theory we propose the category of idealised abstraction that has as its starting point the logical structure of Newtonian mechanics rather than the cognitive state of uninstructed students.     

A Conceptual Examination of College Athletes’ Role Conflict Through the Lens of Conservation of Resources Theory

In this conceptual article, we seek to extend the domain of the conservation of resources (COR) theory to the collegiate student–athlete population in the context of academic–athletic role conflict and stress. Aside from reviewing the direct effects academic–athletic role conflict may have on psychological strain, this conceptual study also continues to build on the theory by proposing mediational pathways of role conflict, and the moderating effects of personal characteristics and social support on the stressor–strain relationship. Although this theoretical framework has been mainly applied in the work–family context, it could be proven useful in alleviating the pressures resulting from student–athletes’ competing roles by providing stress-coping strategies. Focusing on addressing student–athletes’ challenges in managing their college careers, the study provides a theoretical foundation for enhancing student–athletes’ well-being and collegiate experiences. Implications for managerial practices and research are discussed.     

A Comparison of Different Conceptual Change Pedagogies Employed Within the Topic of “Sound Propagation”

The purpose of this study was to compare different conceptual change methods within a topic on ‘sound propagation’. The study was conducted with 80 grade 5 students (aged 11–12 year old) drawn from four cohort classes in an elementary school on the north coast of Black Sea Region in Turkey. While one class was assigned as a control group, the others formed experimental groups (one with a conceptual change text, one with analogies presented as computer animations and one with a combination of conceptual change text, analogies and computer animations). A questionnaire with 10 two-tier questions was administered as a pretest a week before the teaching intervention, and the same test was re-administered immediately after the intervention as a post-test. The questionnaire was also employed as a delayed post-test 3 weeks after the teaching intervention. The experimental groups performed significantly better in the post-test that the control group (p < 0.05). Within the experimental groups, the group exposed to a combination of the conceptual change text, analogies and computer animations performed best on the post-test and the delayed post-test (p < 0.05). Overall the study indicated that the intervention that employed the entire suite of conceptual change pedagogies produced the best learning outcomes.     

Is There Any Change in Science Educational Reforms? A sociological study of theories of instruction

This study analyzes the theory of instruction legitimized by the Ministry of Education in the present reform (1991) by comparison with the previous reform (1975), in order to find out possible changes in the teacher-student relation. The study is focused on the syllabuses of the discipline of Natural Sciences of Years 5/6 and 7, and is theoretically based on Bernstein's theory of pedagogic discourse. The results showed that there are differences between the 1975 and the 1991 reforms, which reveal a change from a more self-regulative theory of instruction to a mixed theory of instruction. This is particularly evident for Years 5/6 of schooling.     

Does Classroom Explicitation of Initial Conceptions Favour Conceptual Change or is it Counter-Productive?

This research investigates the effect of classroom explicitation of initial conceptions (CEIC) on conceptual change in the context of learning electricity. Eight hundred and seventy five thirteen year-olds were tested in laboratory conditions to see if CEIC is or is not a productive step toward conceptual change. All students experienced a problem-based pedagogical treatment called “the electronic challenge.” The randomly determined experimental group was also exposed to CEIC. Data shows a significant beneficial effect of CEIC and no unwanted “contamination effect”, particularly for female subjects.     

How Can Blogging Help Teachers Realize the Goals of Reform-based Science Instruction? A Study of Nine Classroom Blogs

Science teachers struggle with meeting curricular goals outlined by professional organizations within the constraints of traditional school. Engaging science learners as a community who collaboratively and creatively co-construct scientific understanding through inquiry requires teachers to adopt new tools as well as a different mindset about the kind of classroom culture they need to nurture. Classroom blogs (i.e., blogs that are managed by a teacher for his/her students to post their work and exchange ideas) have been purported in the literature as offering unique opportunities to achieve this goal, although with little empirical support thus far. To fill this gap, nine classroom blogs were selected through an extensive search, and systematically analyzed to determine how the teachers’ instructional designs and classrooms’ enactment were able to capitalize on the specific affordances blogging may offer to support reform-based learning goals. The shift in teacher mindset needed to realize blogging affordances occurred as teachers engaged with students in the process of ‘living’ the classroom blog.     

Is There a Magnet-School Effect? A Multisite Study of MSAP-Funded Magnet Schools

Magnet schools are one of the largest sectors of choice schools in the United States. In this study, we explored the heterogeneity in magnet-school effects on student achievement by examining 24 magnet schools, funded under the Magnet Schools Assistance Program (MSAP), in 5 school districts across 4 states. The magnet effects were synthesized across schools with a multilevel variance-known analysis, using the school-level effects estimated with a propensity score matched regression approach. Results indicated significant variation in magnet effects on student outcomes, with some magnet schools showing positive effects, and others showing negative effects. This variation can be explained by program implementation and magnet support.     

Enhancing Conceptual Change in Preschool Children’s Representations of Light: A Sociocognitive Approach

The aim of this study is to investigate the effect of a sociocognitive teaching strategy on young children’s understanding of light. It explores their understanding of the concept of light as an entity that is transmitted independently of the light source and the final receiver. The study was conducted in three phases: pretest, teaching intervention, and post-tests. The sample consisted of 170 preschool children who were assigned to two groups. The children in the first group participated in activities which adopted a sociocognitive approach. In the context of this approach, a familiar metaphor was introduced in order to facilitate children to construct a “precursor model” about light. The children in the second group participated in activities with the same teaching objectives, but adopting an empiricist perspective. Statistical analysis using the Mann–Whitney U test indicated that the cognitive progress of the sociocognitive group was more significant than the progress of the empiricist group. This provides evidence for the effect of the sociocognitive strategy on enhancing children in constructing a “precursor model” for the concept of light.     

Supporting Teachers’ Use of Technology in Science Instruction Through Professional Development: A Literature Review

Professional development is critical in supporting teachers’ use of technological tools in classrooms. This review of empirical research synthesizes the effective elements of professional development programs that support science teachers in learning about technology integration. Studies are examined that explore how professional development supports technology use within inquiry-based and traditional science instruction. Implications for future research are discussed in four areas: understanding and building on teachers’ beliefs about science and technology; supporting teacher learning by supporting teachers’ examination of students’ work; using technology to support teacher communities and social networks; and sustaining teachers’ learning beyond formal professional development programs.

The Effect of Conceptual Change Pedagogy on Students’ Conceptions of Rate of Reaction

This paper reports on an investigation of the effect of conceptual change pedagogy on students’ conceptions of ‘rate of reaction’ concepts. The study used a pre-test/post-test non-equivalent comparison group design approach and the sample consisted of 72 Turkish grade-11 students (aged 16–18 years) selected from two intact classrooms. The ‘Rate of Reaction’ Concept Test comprising 9 lead and 10 sub-questions (total 19 items) was employed. The results suggest that the teaching intervention helped the students to overcome their alternative conceptions and to store their newly structured knowledge in their long-term memories. It is suggested that combining different conceptual change methods such conceptual change text/refutation text, argumentation with the intervention used here may be more effective in reducing student alternative conceptions.     

Constraints on Conceptual Change: How Elementary Teachers’ Attitudes and Understanding of Conceptual Change Relate to Changes in Students’ Conceptions

Like their students, teachers may hold a variety of naïve conceptions that have been hypothesized to limit their ability to support students’ learning. This study examines whether changes in elementary students’ conceptions are related to their teachers’ content knowledge, attitudes, and understanding of conceptual change. The study takes place in the context of the adoption of a new unit on seasonal change in which students build and use sundials to observe seasonal differences in the apparent motion of the Sun across the sky. A mixed-method approach is used. Data sources include pre- and post-tests for students and teacher interviews and questionnaires. Results indicate that changes in students’ conceptions may be related to their teachers’ knowledge of the content, attitudes toward science, and understanding of conceptual change. One teacher had low attitude toward science and limited knowledge of conceptual change. After instruction, her students’ responses became less accurate but more homogeneous than before instruction. The other teacher had high attitude and moderate knowledge of conceptual change. Her students showed gains from pre- to post-test, including responses that were more scientifically accurate than the teachers’ initial answers.     

Is Social Media Too Social for Class? A Case Study of Twitter Use

This qualitative case study examined Twitter use by undergraduate and graduate students in three classes. Previous studies have shown that while some faculty use Twitter, few are incorporating it into classes despite many recommendations for such use. This study examined how students perceived Twitter as a classroom tool. As an optional activity, many started with Twitter but fewer continued through the semester. The study reports on content and counts of tweets as well as student self-reports on usage and interest. The researchers found students enjoyed being consumers of tweets but seldom retweeted or replied. Incorporating Twitter in courses will require careful consideration of scaffolding, modeling, privacy and course design. Questions remain as to whether the informal social focus of Twitter may overwhelm attempts to use it in more structured educational settings.     

Understanding the Development of a Hybrid Practice of Inquiry-Based Science Instruction and Language Development: A Case Study of One Teacher’s Journey Through Reflections on Classroom Practice

This qualitative case study looks closely at an elementary teacher who participated in professional development experiences that helped her develop a hybrid practice of using inquiry-based science to teach both science content and English language development (ELD) to her students, many of whom are English language learners (ELLs). This case study examines the teacher’s reflections on her teaching and her students’ learning as she engaged her students in science learning and supported their developing language skills. It explicates the professional learning experiences that supported the development of this hybrid practice. Closely examining the pedagogical practice and reflections of a teacher who is developing an inquiry-based approach to both science learning and language development can provide insights into how teachers come to integrate their professional development experiences with their classroom expertise in order to create a hybrid inquiry-based science ELD practice. This qualitative case study contributes to the emerging scholarship on the development of teacher practice of inquiry-based science instruction as a vehicle for both science instruction and ELD for ELLs. This study demonstrates how an effective teaching practice that supports both the science and language learning of students can develop from ongoing professional learning experiences that are grounded in current perspectives about language development and that immerse teachers in an inquiry-based approach to learning and instruction. Additionally, this case study also underscores the important role that professional learning opportunities can play in supporting teachers in developing a deeper understanding of the affordances that inquiry-based science can provide for language development.     

Effects of Conceptual Change Texts and Laboratory Experiments on Fourth Grade Students’ Understanding of Matter and Change Concepts

The purpose of this study was to investigate whether conceptual change texts and laboratory experiments are effective in overcoming misconceptions and whether the concepts were acquired permanently when these methods were utilized. In this study, we addressed some topics from the “Matter and Change” unit in science and technology class of elementary 4th grade. Students from three classes of an elementary school participated in the study (N = 104). Students’ misconceptions were determined by administering the “Matter Concept Test” before, immediately after and 13 weeks after the instructional period. The results of the study showed that both conceptual change texts and experiment method were more successful than traditional instruction in overcoming the misconceptions and acquiring permanent knowledge. However, there was not a significant difference between these two alternative approaches in terms of reducing the misconceptions.     

A Longitudinal Correlational Study of Students’ Performance in Supervised Industrial Work Experience and Classroom Instruction

Scholars in technology education are of the view that there should be some relationship between supervised industrial work‐experience and classroom instruction in order that the theory learned at school would have relevance to practice at the work place, especially as supervised industrial work‐experience has become an important component of well‐planned technology education programmes.

This study was therefore designed to determine the nature and extent of the relationship between supervised industrial work‐experience and classroom instruction. A research sample of 64 (comprising of 30 mechanical, 20 electrical and 14 civil) engineering technology students were alternatively exposed for three years to classroom instruction and its consequent sessional examinations on the one hand and supervised industrial work‐experience and the consequent performance assessment process on the other. Performance scores‐‐in percentages‐‐were collected from the two research situations. Product moment correlation coefficients were computed for the pairs of performance scores; first all the students’ scores were analysed together and then they were analysed in each engineering specialty.

It was found that:

(1) generally there was no statistically significant relationship between the students’ performances in classroom instruction and supervised industrial work‐experience;

(2) additionally (a) statistically significant relationship did not exist between students’ performances during the different periods of supervised industrial work‐experience and (b) there was a statistically significant relationship between the students’ performances in the classroom‐instruction situation.

It was recommended that industries should participate in the preparation of curricula for technology education programmes; and should train students on projects that have educational value and practical utility while more industrial‐work‐related instructions should be provided in technology education programmes.     

Is What Glitters Really Gold? A Quasi-Experimental Study of First-Year Seminars and College Student Success

First-year seminars are frequently designed to help students adjust to and succeed in college. Although considerable literature has explored this topic, many previous studies may have notable problems with self-selection, since students who choose to participate are likely more motivated academically than those who do not. Therefore, this study used quasi-experimental analyses within a large, longitudinal, multi-institutional dataset to explore the link between seminar participation and several student success outcomes. Overall, the use of propensity score analyses substantially alters the results, such that first-year seminars are positively associated with first-year college satisfaction, but they have no effect on fourth-year satisfaction, college grades, retention, or four-year graduation within the full sample. This lack of impact is largely consistent regardless of whether the seminar is designed to engage students in academic inquiry or to promote orientation and academic success. Additional analyses observed some differential effects of first-year seminars by race/ethnicity, ACT score, and sex; the most consistent finding is that first-year seminars appear to promote the college grades and college satisfaction of Black students. Implications for future research and practice are discussed.
