The Collaboration of Cooperative Learning and Conceptual Change: Enhancing the Students’ Understanding of Chemical Bonding Concepts

The main purpose of this study was to investigate the effects of cooperative learning based on conceptual change approach instruction on ninth-grade students’ understanding in chemical bonding concepts compared to traditional instruction. Seventy-two ninth-grade students from two intact chemistry classes taught by the same teacher in a public high school participated in the study. The classes were randomly assigned as the experimental and control group. The control group (N?=?35) was taught by traditional instruction while the experimental group (N?=?37) was taught cooperative learning based on conceptual change approach instruction. Chemical Bonding Concept Test (CBCT) was used as pre- and post-test to define students’ understanding of chemical bonding concepts. After treatment, students’ interviews were conducted to observe more information about their responses. Moreover, students from experimental groups were interviewed to obtain information about students’ perceptions on cooperative work experiences. The results from ANCOVA showed that cooperative learning based on conceptual change approach instruction led to better acquisition of scientific conceptions related to chemical bonding concepts than traditional instruction. Interview results demonstrated that the students in the experimental group had better understanding and fewer misconceptions in chemical bonding concepts than those in the control group. Moreover, interviews about treatment indicated that this treatment helped students’ learning and increased their learning motivation and their social skills.     

Students’ Independent Use of Screencasts and Simulations to Construct Understanding of Solubility Concepts

As students increasingly use online chemistry animations and simulations, it is becoming more important to understand how students independently engage with such materials and to develop a set of best practices for students’ use of these resources outside of the classroom. Most of the literature examining students’ use of animations and simulations has focused on classroom use with some studies suggesting that better outcomes are obtained when students use simulations with minimal guidance while others indicate the need for appropriate scaffolding. This study examined differences with respect to (1) student understanding of the concept of dissolution of ionic and covalent compounds in water and (2) student use of electronic resources when students were asked to complete an assignment either by manipulating a simulation on their own or by watching a screencast in which an expert manipulated the same simulation. Comparison of students’ pre- and posttest scores, answers to assignment questions, near-transfer follow-up questions, and eye-tracking analysis suggested that students who viewed the screencast gained a better understanding of the dissolving process, including interactions with water at the particulate level, particularly for covalent compounds. Additionally, the eye tracking indicated that there were significant differences in the ways that the different treatment groups (screencast or simulation) used the electronic resources.     

Applying the Science of Learning to the Learning of Science: Newton’s Second Law of Motion

Science teaching and learning require knowledge about how learning takes place (cognition) and how learners interact with their surroundings (affective and sociocultural factors). The study reported on focussed on learning for understanding of Newton’s second law of motion from a cognitive perspective that takes social factors into account. A cognitive refinement instructional approach (CRIA) was used to organise and sequence learning activities, while students were engaged through inquiry and group work. Students’ real-life experiences were used as starting point of the learning sequence. The efficiency of the sequence was determined with the aid of the Force Concept Inventory (FCI) and complemented with the students’ reflections on the sequence, showing their epistemological preferences. The results indicated that a CRIA aided in constructing more coherent scientific knowledge and enhanced understanding, while reducing misconceptions on the topic. In their reflections, the students acknowledged that experiential and experimental evidence, as well as guided formation of a scientific explanatory framework, are foundational for a deeper understanding of the challenging topic.     

Investigating the Influence of Motivation on Students’ Conceptual Learning Outcomes in Web-based vs. Classroom-based Science Teaching Contexts

The purposes of this study were to investigate students’ conceptual learning outcomes and the effect of motivation on students’ conceptual learning outcomes in two different contexts: a Web-based and a classroom-based instruction, which incorporated the Dual Situation Learning Model (DSLM). Nine classes of Grade eight students (N = 190) were involved in the study; five classes participated in a Web-based context and four classes in a regular classroom-based context. The topic covered was chemical reaction. Students’ conceptual change outcomes were assessed using eight two-tier pre/post conceptual tests during the instruction and the reaction rate integrated conceptual test at the end of the instruction. Students’ motivation data were collected in the beginning and during instruction using the items from the Students’ Motivation Toward Science Learning (SMTSL) questionnaire. The data were analyzed using ANOVA, ANCOVA, bivariate correlation, and multiple regression analysis. Findings revealed that students’ motivational factors were correlated significantly with their conceptual learning outcomes in both Web-based and classroom-based science teaching. In the Web-based context, students’ motivation during the Web-based learning played a more important role on students’ conceptual learning outcomes than before learning.     

An Exploratory Study of Teachers’ and Students’ Use of Multi‐modal Representations of Concepts in Primary Science

As part of a long‐term research study to enhance science learning, this paper reports on an exploratory study aimed at identifying initial beliefs and practices of a group of teachers and students (Years 4–6) in Australia when the students engaged with multiple representations of the same science concepts. There is growing recognition in science education research that students need to understand and link different representational modes, such as graphic and verbal modes, in learning to think and act scientifically. This exploratory study used a multi‐site case‐study approach employing qualitative and quantitative methods. The findings indicated that while teachers used various modes to engage students and assess learning, they were not systematic in their focus on student integration and translation across modes. The study found that various factors affected students’ understanding of different modes, and that students who recognised relationships between modes demonstrated better conceptual understandings than students who lacked this knowledge.     

Understanding the Students’Contribution to EFL Learning

One can view life from many different perspectives, and each perspective will reveal different aspects and details. As a teaching professional, teachers’ major aim is to help learners. This is the major justification for their career. If they don’t help learners, they will not enjoy teaching. Helping learners requires certain skills on the part of the teacher.     

High-School Students’ Epistemic Knowledge of Science and Its Relation to Learner Factors in Science Learning

The purpose of this study was to develop and validate an online contextualized test for assessing students’ understanding of epistemic knowledge of science. In addition, how students’ understanding of epistemic knowledge of science interacts with learner factors, including time spent on science learning, interest, self-efficacy, and gender, was also explored. The participants were 489 senior high school students (244 males and 245 females) from eight different schools in Taiwan. Based on the result of an extensive literature review, we first identified six factors of epistemic knowledge of science, such as status of scientific knowledge, the nature of scientific enterprise, measurement in science, and so on. An online test was then created for assessing students’ understanding of the epistemic knowledge of science. Also, a learner-factor survey was developed by adopting previous PISA survey items to measure the abovementioned learner factors. The results of this study show that; (1) by factor analysis, the six factors of epistemic knowledge of science could be grouped into two dimensions which reflect the nature of scientific knowledge and knowing in science, respectively; (2) there was a gender difference in the participants’ understanding of the epistemic knowledge of science; and (3) students’ interest in science learning and the time spent on science learning were positively correlated to their understanding of the epistemic knowledge of science.     

Understanding the Influence of Learners’ Forethought on Their Use of Science Study Strategies in Postsecondary Science Learning

Understanding self-regulation in science learning is important for theorists and practitioners alike. However, very little has been done to explore and understand students’ self-regulatory processes in postsecondary science courses. In this study, the influence of science efficacy, learning value, and goal orientation on the perceived use of science study strategies was explored using structural equation modeling. In addition, the study served to validate the first two stages of Zimmerman's cyclical model of self-regulation and to address the common methodological weakness in self-regulation research in which data are all collected at one point after the learning cycle is complete. Thus, data were collected across the learning cycle rather than asking students to reflect upon each construct after the learning cycle was complete. The findings supported the hypothesized model in which it was predicted that self-efficacy would significantly and positively influence students’ perceived science strategy use, and the influence of students’ valuation of science learning on science study strategies would be mediated by their learning goal orientation. The findings of the study are discussed and implications for undergraduate science instructors are proposed.     

Learning Theory as Teaching Resource: Enhancing Students’ Understanding of Economic Concepts

A group of experienced secondary school teachers used a novel learning theory as a resource for planning and carrying out their teaching of a difficult economic concept. Their students mastery of this concept after a series of three lessons was compared with the mastery of the same concept by students who were taught by another group of teachers under the same conditions except for the use of the theory. The difference in learning outcomes was extreme. Observations of what was happening in the classrooms showed subtle but decisive differences correlated with the differences in outcome. These differences were interpreted in terms of the theory used by the first group, and the results seem to give support to the theoretical claim that for any specific object of learning there is a necessary pattern of variation and invariance that the learners must experience in order to appropriate the object of learning in question and thus by bringing out that pattern in the learning situation, the likelihood of that object of learning being appropriated is enhanced. Furthermore, this study shows how the understanding of the simultaneous change in the supply of and the demand for a certain good affects its market price can be brought about in a powerful way.     

Manipulative Use and Elementary School Students’ Mathematics Learning

Using data from the Early Childhood Longitudinal Study (ECLS) 1998/1999, we examine the relationship between elementary students’ (K–5) manipulative use and mathematics learning. Using a cross-sectional correlational analysis, we found no relationship between manipulative use and student mathematics achievement. However, using a longitudinal analysis, we documented a positive relationship between manipulative use and student mathematics learning during their elementary school years (K–5). From a teaching and learning perspective, these findings provide important evidence of the influence of long-term manipulative use on students’ overall learning. From policy and methodological perspectives, these findings provide evidence for the importance of modeling student learning (as opposed to achievement) when studying the effectiveness of instructional strategies.     

Relational Analysis of College Science‐Major Students’ Epistemological Beliefs Toward Science and Conceptions of Learning Science

In recent years, there has been an increasing interest among educational researchers in exploring the relationships between learners’ epistemological beliefs and their conceptions of learning. This study was conducted to investigate these relationships particularly in the domain of science. The participants in this study included 407 Taiwanese college science‐major students. All of them responded to two major questionnaires, one assessing their scientific epistemological beliefs (SEBs) and the other one probing their conceptions of learning science (COLS). The SEB questionnaire included four factors: “certainty,” “source,” “development,” and “justification” of science knowledge. The COLS survey consisted of six factors in a hierarchical order, that is, learning science as “memorizing,” “preparing for tests,” “calculating and practicing,” “increasing one’s knowledge,” “application,” and “understanding and seeing in a new way.” The students’ confidence and interest toward learning science were also assessed by additional questionnaire items. Stepwise regression analyses, in general, showed coherence between students’ SEBs and their COLS, indicating that the sophistication of SEBs was consistent with less agreement with lower‐level COLS (such as “memorizing” and “preparing for tests”) as well as more agreement with higher‐level COLS (such as “understanding and seeing in a new way”). However, the SEB’s “justification” factor was positively related to almost all of COLS factors from the lower‐level to higher‐level. This study finally found that among all of the SEB and COLS factors, the “preparing for tests” factor in COLS was the solely significant variable for predicting students’ interest in science and confidence toward learning science.     

Students’ Perception of Co‐operative Learning in Earth Science Fieldwork

This paper reports on a small‐scale study of students’ perceptions of selected aspects concerning the organisation of, and learning from, fieldwork. Two main findings emerge. (a) In the choke of working partners, students either seek partners whom they regard as capable of making positive contributions to the fulfilment of the learning tasks, or they opt for friendship groups. In the case of the former, the qualities looked for are predominantly subject knowledge and subject‐related skills: competence in the management of group learning does not appear as a major consideration. (b) Although the outcomes from group work were invariably judged to be positive, a large minority of students appeared to regard themselves as contributors to, rather than beneficiaries from, such work. These students judged the extent of their learning from group work as low or very low.     

Investigating Students’ Conceptions of Technology-Assisted Science Learning: a Drawing Analysis

This study investigated high school students’ conceptions of technology-assisted science learning via drawing analysis, and explored how students with different degrees of computer experience and science learning self-efficacy may show different conceptions via their drawings. The participants included 335 senior high school students in Taiwan (179 male and 156 female). All of them were asked by guiding questions to make two drawings to represent their conceptions of technology-assisted science learning in actual and ideal contexts, respectively. Their background information including computer experience and science learning self-efficacy were obtained using self-reported questionnaires. Through drawing analysis, seven categories of conceptions of technology-assisted science learning were identified, including types of technology, location of learning, types of learning activities, content of learning, participants of learning activities, affordance of learning technology, and effects of learning technology. The results further revealed that the students’ conceptions of actual and ideal technology-assisted science learning significantly differed in some sub-categories of all categories except the category of participants of learning activities. Moreover, students’ computer experience and science learning self-efficacy may link to different conceptions of technology-assisted science learning. Future research and directions are also discussed.

     

Connecting Soccer to Middle School Science: Latino Students’ Passion in Learning

Building on a pedagogical model designed to support the teaching and learning of the language of science investigation practices with middle school emergent bilingual learners, we developed a series of soccer and science investigations to promote interest and engagement in science learning. We used assemblage theory to study how students engaged in and acted within this bilingual curriculum situated in an afterschool soccer practice context. We found that soccer, a passion for several Latino students, can be used as a cultural tool for science teachers to support the emerging bilingual students’ learning process. Implications for educators and researchers considering ways of integrating diverse students’ cultural practices and passions with culturally sustaining pedagogies for science teaching and learning are discussed.     

Effects of Teacher Professional Development and Science Classroom Learning Environment on Students’ Science Achievement

Collateral Learning in Science: Students’ responses to a cross‐cultural unit of work

The purpose of this study was to investigate the nature of students’ responses to a cross‐cultural science unit entitled “Maintaining health.” The unit was designed to help students to build bridges between their traditional practices and beliefs and western science concepts. This paper reports students’ responses to a pre‐test and post‐test, and their reflections on their learning. The responses were analysed using the collateral learning model. There was evidence of parallel, dependent, and secured collateral learning. The implications for science teaching and for assessing science learning are discussed.     

Do Science Teachers Distinguish Between Their own Learning and the Learning of Their Students?

Learning beliefs influence learning and teaching. For this reason, teachers and teacher educators need to be aware of them. To support students’ knowledge construction, teachers must develop appropriate learning and teaching beliefs. Teachers appear to have difficulties when analysing students’ learning. This seems to be due to the inability to differentiate the beliefs about their students’ learning from those about their own learning. Both types of beliefs seem to be intertwined. This study focuses on whether pre-service teachers’ beliefs about their own learning are identical to those about their students’ learning. Using a sample of pre-service teachers, we measured general beliefs about “constructivist” and “transmissive” learning and science-specific beliefs about “connectivity” and “taking pre-concepts into account”. We also analysed the development of these four beliefs during teacher professionalisation by comparing beginning and advanced pre-service teachers. Our results show that although pre-service teachers make the distinction between their own learning and the learning of their students for the general tenets of constructivist and transmissive learning, there is no significant difference for science-specific beliefs. The beliefs pre-service teachers hold about their students’ science learning remain closely tied to their own.     

Preparing Teachers’ to Raise Students’ Mathematics Learning

The purpose of this study was to investigate the effectiveness of the ORIGO Stepping Stones program in a large suburban school district in the Midwestern U.S.. The sample included 11 elementary schools that implemented the program during the 2013–2016 school years. Findings are presented from teacher surveys, classroom observations, and analysis of standardized student mathematics achievement scores on the Northwest Evaluation Association Measurement of Academic Progress (NWEA MAP). Using multilevel models, the program did not demonstrate a detectably larger effect on mathematics achievement than the comparison. Classroom observations and views of teachers that support program implementation were explored. In terms of fidelity of implementation, findings suggested that the program was delivered differently from how it was intended. With respect to researchers and policymakers, the approach used to evaluating mathematics program effectiveness is informative and could be used as part of larger accountability systems.
