Middle school students’ learning of mechanics concepts through engagement in different sequences of physical and virtual experiments

ABSTRACT

Physical and virtual experimentation are thought to have different affordances for supporting students’ learning. Research investigating the use of physical and virtual experiments to support students’ learning has identified a variety of, sometimes conflicting, outcomes. Unanswered questions remain about how physical and virtual experiments may impact students’ learning and for which contexts and content areas they may be most effective. Using a quasi-experimental design, we examined eighth grade students’ (N?=?100) learning of physics concepts related to pulleys depending on the sequence of physical and virtual labs they engaged in. Five classes of students were assigned to either the: physical first condition (PF) (n?=?55), where students performed a physical pulley experiment and then performed the same experiment virtually, or virtual first condition (VF) (n?=?45), with the opposite sequence. Repeated measures ANOVA’s were conducted to examine how physical and virtual labs impacted students’ learning of specific physics concepts. While we did not find clear-cut support that one sequence was better, we did find evidence that participating in virtual experiments may be more beneficial for learning certain physics concepts, such as work and mechanical advantage. Our findings support the idea that if time or physical materials are limited, using virtual experiments may help students understand work and mechanical advantage.     

Assessing high-school students’ ability to direct their learning

Theory on student learning provides that students are able to direct their learning when they have metacognitive knowledge about their own learning processes. In this article, a preliminary attempt to assess untrained high-school students’ metacognitive knowledge of learning processes as an ability through multiple-choice questions is reported. In three studies, item selection was established for ninth graders at the end of their school year. Also, in the final study the results showed that the ninth-grade students’ self-reported use of learning and studying strategies, study techniques, school learning and tiresome academic subjects related significantly to their metacognitive knowledge regarding learning processes. In the discussion, the practical consequences for school assessment are explicated and future research questions are raised.     

Effects of different evaluative feedback on students’ self-efficacy in learning

Two studies examined the effects of four types of teachers’ evaluative feedback on Chinese students’ self-efficacy in English vocabulary acquisition. In Study 1, a random sample of Grade 8 students (N = 79) learned prefixes and received either formative or summative feedback after failure in test. The results showed that students who received summative feedback showed a larger decrease in their self-efficacy than those who received formative feedback. In Study 2, a random sample of Grade 7 students (N = 77) went through similar procedures as in Study 1 except that students received either self-referenced or norm-referenced feedback. The results showed that self-referenced feedback was more beneficial to students’ self-efficacy than norm-referenced feedback. The influences of teachers’ evaluation and feedback on students’ self-efficacy are discussed.     

Assessing students’ experiences of teaching–learning environments and approaches to learning: Validation of a questionnaire in different countries and varying contexts

The study examined the use of the modified Experiences of Teaching and Learning Questionnaire (ETLQ) in the Finnish context by focusing on its factor structures and comparing them with those for British data. A total of 2,509 Finnish and 2,710 British students completed the questionnaire. The comparison of the factor structures were conducted using exploratory structural equation modelling (ESEM) and a transformation analysis. Although the differences between the factor structures prevented a combined analysis, the structures were highly similar in the two contexts. The ETLQ appears to be a sufficiently robust and reliable instrument for use across countries and, in addition, at either the level of the degree subject or the single course module.     

The effect of a conceptual change approach on understanding of students’ chemical equilibrium concepts

The purpose of this study was to compare the effects of a conceptual change approach over traditional instruction on tenth‐grade students’ conceptual achievement in understanding chemical equilibrium. The study was conducted in two classes of the same teacher with participation of a total of 44 tenth‐grade students. In this study, a pre‐test/post‐test control group semi‐experimental design pattern was used. During teaching the topic of chemical equilibrium concepts in the chemistry curriculum, a conceptual change approach was applied in the experimental group whereas traditional instruction was followed in the control group. Data were analysed with an independent samples t‐test, and an analysis of covariance using the pre‐test scores as the covariate. The results showed that the conceptual change approach was statistically more effective than traditional instruction in terms of students’ conceptual understanding. After the six‐week intervention, interviews were conducted with 18 selected students in the study. In the interviews a prevailing alternative conception was detected beside many alternative conceptions. When they were asked to compare equilibrium constants of two different reactions they mostly responded to mean that ‘the bigger the mol number of the products, the bigger the equilibrium constant’ without considering what proportions the reactants were transformed into products in a reaction. Also, in this study a two‐tier multiple choice test was developed related to chemical equilibrium to detect students’ concepts and alternative concepts.     

Exploring teachers’ and students’ conceptions of learning in two further education colleges

The Learning to Learn in Further Education Research Project (L2L) is coordinated by the Campaign for Learning and run by researchers at Newcastle and Glasgow Universities. The project involves teachers at two further education (FE) colleges, Lewisham and Northumberland, using practitioner enquiry methodologies to explore and share what works in learning and teaching in their context.

This article uses data collected as part of the larger project to explore how the combination of societal, political and economic forces that have shaped provision in this sector impact on students’ and teachers’ views of learning when compared with the compulsory sector. The authors sought to establish whether factors such as an ethos of performativity and instrumentalisation of the curriculum were indeed at play in shaping understandings of teaching and learning, and what it means to learn in an FE context.

Telephone interviews with 16 teachers provided evidence that such pressures were impacting on teaching despite the ambitions of the teachers that their practice be responsive to student need rather than curricular imperatives. Involvement with the university and the L2L project was seen by many as a way of countering perceived constraints on their freedom to exercise professional judgement. Face-to-face mediated interviews with 64 learners drawn from a number of qualification routes revealed a simplistic model for learning based around listening and the practising of skills. The authors discuss the extent to which students appear to understand this as building the necessary foundations for later, more sophisticated learning rather than as requirements of their courses per se.     

What can moment-by-moment learning curves tell about students’ self-regulated learning?

Many students in primary education learn arithmetic using adaptive learning technologies (ALTs) on tablets every day. Driven by developments in the emerging field of learning analytics, these technologies adjust problems based on learners' performance. Yet, until now it is largely unclear how students regulate their learning with ALTs. Hence, we explored how learners regulate their effort, accuracy and learning with an ALT using moment-by-moment learning curves. The results indicated that moment-by-moment learning curves did reflect students’ accuracy and learning, but no associations with effort were found. Immediate drops were associated with high prior knowledge and suboptimal learning. Immediate peaks were associated with robust learning and pointed to effective student regulation. Close multiple spikes showed moderate learning and lower initial levels of accuracy but, with system support, these students seemed able to regulate their learning. Separated multiple spikes indicated reduced learning and accuracy and potentially signal the inability of students to regulate their learning. In this light, moment-by-moment learning curves seem to be valuable indicators of accuracy regulation during learning with ALTs and could potentially be used in interventions to support SRL with personalized visualizations.     

Role of anomalous data and epistemological beliefs in middle school students’ theory change about two controversial topics

The question of theory change is crucial in knowledge construction, particularly in the process of conceptual change. This study was designed to investigate two factors that, in addition to initial theory preference, may play a crucial role in the process of theory change, that is, students’ interpretation of anomalous data on two controversial topics (the dinosaur extinction and the construction of the Giza pyramids in Egypt) and their epistemological beliefs about the nature of knowledge. Canonical correlation analyses suggested for both topics an association, stronger for the dinosaur extinction topic, between (a) acceptance of anomalous data (rated both as valid and inconsistent with the held theory), initial theory preference, epistemological belief in Certain Knowledge and (b) theory change. Data obtained from structure coefficients in canonical correlation analyses indicate that acceptance of anomalous data significantly contributed the most to theory change whereas the epistemological belief contributed the least. Finally, educational implications are drawn.     

Facilitating conceptual change in ninth grade students’ understanding of human circulatory system concepts

The purpose of this study was to investigate the effectiveness of the conceptual change text oriented instruction over traditionally designed instruction on ninth grade students’ understanding of the human circulatory system concepts, and their retention of this understanding. The subjects of this study consist of 73 ninth grade female students from two classes of a basic school in Jordan. One of the classes was randomly assigned as an experimental group in which conceptual change text oriented instruction was implemented, and the other class was randomly assigned as a control group in which students were instructed by traditionally designed biology instruction. Results showed that students exposed to conceptual change oriented instruction had better understanding of the human circulatory system concepts than those exposed to traditional instruction. The results also showed that the conceptual change text oriented instruction was significantly better than the traditional instruction in retention of this understanding.     

Teachers’ assessments of students’ learning of mathematics

This paper reports a study of the classroom assessment practices of 12 sixth form college mathematics teachers in Malta. It explores the extent to which these teachers are knowledgeable about their students’ learning of mathematics and the implications that this has for their classroom practices. It reveals that these teachers’ knowledge of their students’ understanding of certain mathematical concepts is fairly limited. It then goes on to discuss this phenomenon in terms of a process that can hinder rather than promote learning. The research illuminates the position of teachers who appear to lack certain detailed information about their students which, it can be argued, could inform more effective teaching strategies. The paper concludes by exploring possible implications for similar situations where learning could be enhanced by more effective classroom assessment strategies and their use to inform future teaching and learning activities.     

A stratified study of students’ understanding of basic optics concepts in different contexts using two‐tier multiple‐choice items

A large scale study involving 1786 year 7–10 Korean students from three school districts in Seoul was undertaken to evaluate their understanding of basic optics concepts using a two‐tier multiple‐choice diagnostic instrument consisting of four pairs of items, each of which evaluated the same concept in two different contexts. The instrument, which proved to be reliable, helped identify several context‐dependent alternative conceptions that were held by about 25% of students. At the same time, students’ performance on the diagnostic test correlated with the location of the schools, students’ achievement in school science and their attitudes to science learning. However, students’ grade levels had limited influence on their understanding of basic concepts in optics as measured by the instrument.     

Graduate students’ conceptions of university teaching and learning: formation for change

The paper introduces a framework concerning conceptions of teaching and learning of advanced graduate students and the trajectory of change in their conceptions following a formal course on course design and teaching. Students were enrolled in six sections of this graduate course, two offered in a 6-week format and 4 in a 13-week format. The courses were taught by three different instructors. Data were obtained from 88 doctoral students before and after the course using four questions pertaining to the meaning of effective teaching, effective learning, role of the teacher, and role of the learner. Using an open coding procedure, four conceptions were identified. These were transmitting knowledge, preparing context/managing instruction, promoting course learning, and promoting life-long learning. The generalized linear model procedure was used to conduct within and between group pre and post course comparisons. Overall, there was a significant change in response frequency ratios in all four categories across all courses, indicating a decrease in the responses in the first two categories and an increase in the frequency of responses in the last two categories. No significant differences were attributed to course type or instructor.     

Re-defining ‘learning about religion’ and ‘learning from religion’: a study of policy change

The study of how policy processes shape religious education as a curriculum subject, rather than within faith schooling, is relatively unexplored. This paper applies a policy analysis perspective to an important distinction in non-confessional English religious education, which has also been adopted internationally: ‘learning about religion’ and ‘learning from religion’. The changing nature of the distinction in English policy documents from 1994 is examined in the light of three main voices of influence on educational policy: neo-conservatives, neo-liberals and progressives. These changes are also analysed through three policy contexts: influence, text production and practice. Revisions to policy wording are interpreted in the light of this theory, showing the growing significance of neo-liberalism, and the nature of compromise, amendment and ambiguity. The implications for an understanding of the inter-relationship between policy, pedagogy and practice are then considered.     

The effect of two different cooperative approaches on students’ learning and practices within the context of a WebQuest science investigation

The goal of this study was to investigate the effect of two different cooperative learning approaches, namely, the Jigsaw Cooperative Approach (JCA) and the Traditional Cooperative Approach (TCA), on students’ learning and practices/actions within the context of a WebQuest science investigation. Another goal of this study was to identify possible problems that students face within the context of a WebQuest when following either approach and to provide suggestions for developing web-based learning tools that enable students to overcome these problems. The sample of the study consisted of 38 seventh-graders, who, according to their science teachers, had prior experience with TCA and JCA. All participants studied about the ecology, architecture, energy and insulation of CO₂-friendly houses through the use of a WebQuest science investigation. The data collection involved conceptual tests, screen–video captured data and interviews. Results revealed no differences between the two approaches, in terms of enhancing students’ understanding of concepts related to CO₂-friendly houses, because of (a) JCA students’ inability to apply one of the JCA components, namely, teaching one another about learning material they solely studied, and (b) the fact that the JCA students started applying the TCA after failing teaching one another in the context of JCA. Finally, a number of problems that students faced within the context of a WebQuest science investigation when following the JCA or TCA were identified.     

Middle and high school students’ conceptions of climate change mitigation and adaptation strategies

Both scientists and policy-makers emphasize the importance of education for influencing pro-environmental behavior and minimizing the effects of climate change on biological and physical systems. Education has the potential to impact students’ system knowledge – their understanding of the variables that affect the climate system – and action knowledge – their understanding of behaviors that can impact the system. Research on climate change education has largely focused on system and action knowledge that address mitigation while overlooking equally necessary adaptive responses. This study used a pre/post-test format to identify aspects of middle and high school students’ climate system knowledge and action knowledge of both mitigation of and adaptation to climate change. Results indicate that adolescents currently conflate climate change mitigation strategies with unrelated environmental problems far less than in previous surveys. However, students demonstrated limited understanding of adaptive responses to climate change. After engaging in an instructional unit on climate change, students expressed stronger system and action knowledge, but significant misconceptions remained that conflated mitigation of and adaptation to climate change.     

Preservice teacher education students’ epistemological beliefs and conceptions about learning

A questionnaire was administered to 231 Hong Kong preservice teacher education students to examine their epistemological beliefs and conceptions of learning. Pearson correlation analysis showed significant pairs of epistemological beliefs and conceptions of learning. Regression and path analysis showed epistemological beliefs had significant predictor relationships with conceptions of learning. Four structural equation models were proposed to examine the predictive relationships between epistemological beliefs and selected pairs of quantitative and qualitative conceptions of learning, and the models were validated by confirmatory factor analysis. The results support the hypothesis that epistemological beliefs have significant predictive relationships with quantitative and qualitative conceptions of learning, implying epistemological beliefs play an important role in students’ learning. The paper concludes with implications drawn for the future direction of educational practices and research.     

Assessing and tracking students’ problem solving performances in anchored learning environments

The purpose of this randomized experiment was to compare the performance of high-, average-, and low-achieving middle school students who were assessed with parallel versions of a computer-based test (CBT) or a paper-pencil test (PPT). Tests delivered in interactive, immersive environments like the CBT may have the advantage of providing teachers with diagnostic tools that can lead to instruction tailored to the needs of students at different achievement levels. To test the feasibility of CBT, students were randomly assigned to the CBT or PPT test conditions to measure what they had learned from an instructional method called enhanced anchored math instruction. Both assessment methods showed that students benefited from instruction and differentiated students by achievement status. The navigation maps generated from the CBT revealed that the low-achieving students were able to navigate the test, spent about the same amount of time solving the subproblems as the more advanced students, and made use of the learning scaffolds.

Enhancing Thai students’ learning of chemical kinetics

Chemical kinetics is an extremely important concept for introductory chemistry courses. The literature suggests that instruction in chemical kinetics is often teacher‐dominated at both the secondary school and tertiary levels, and this is the case in Thailand – the educational context for this inquiry. The work reported here seeks to shift students from passive learning to more active, student‐centred learning and involved some 413 first year undergraduate science students in Thailand. Drawing on inquiry‐based learning, the participants were asked to design an experiment investigating the reaction of acids and bases. The research findings suggest that participants were able to explain the changes of the rate of a chemical reaction, and developed good conceptual understanding of chemical kinetics both qualitatively and quantitatively. It also showed this more active teaching approach, which is radically different from normal teaching in Thailand, was an enjoyable experience for the students.
