THE RECIPROCAL DETERMINISM OF ONLINE SCAFFOLDING IN SUSTAINING A COMMUNITY OF INQUIRY IN PHYSICS

This study investigated the learning impact of online scafolding in sustaining a community of inquiry in Physics instruction. The students’ a-priori e-learning activities in online discussion were used in leveraging the learning behaviors of the students. Online learning segments were included in the process of developing classroom tasks vis-à-vis with the course intended learning outcomes. This was done in a collegial, constructive and democratic learning towards classroom efcacy through online scafolding techniques. Two sections of 34 students enrolled in NATSC1D (University Physics 1) were used in this study. A questionnaire was adopted in determining the perceived relative magnitude of advantages of the online discussion. Pearson-r correlation results showed a very-highly positive correlation between the students’ a-priori e-learning experiences in online discussion and their success in online scafolding, and a highly to very-highly positive correlation to their performance in classroom interaction, formative assessment and summative evaluations.


INTRODUCTION
The advent of advanced educational technologies is a vast array of digital resources and content in learning that ofers the magnanimity of theories towards educational opportunities.This ofers practices in sustaining a community of inquiry in a dynamic classroom.
Sustaining a community of inquiry in any educative instruction requires greater options for quantity and quality of learning interactions in a collegial learning environment.This ofers the student-learners the opportunity to interact with each other at anytime and anywhere through online discussion tools and facilities.One of the approaches in the sustenance of this community of inquiry is the implementation of the online scafolding in classroom instruction.
Online scafolding creates a technology-based instruction as a way of enriching the educative processes to be more integrative through synchronous and asynchronous learning modalities.It restructures the traditional classroom routines with online learning.
Reciprocal causation is based on the reciprocal determinism theory (Bandura, 1986) that holds the idea that learning behaviors are controlled by cognitive processes.Cognition transforms the individual through imitation, modeling and feedback consists of environmental, individual and other social stimulus that are believed to reshape the learning environment of the student-learner.Cognitive apprenticeship (Brown, et al., 1989) in Anderson (2006) is a form of learning based on collaborative social interaction and social construction of knowledge by enabling the students to acquire and develop cognition as they get involved in a community of practice in a "legitimate peripheral participation".
Astutely, the infuence of Bandura's Social Learning Theory -the notion that most human behavior is learned by observation and in turn codes information that serves as a model for action, appears evident in an online segment of learning (Ryan-Rojas, Douglass & Ryan, 2012).It is postulated that a person's behavior is infuenced by the environment and vice versa, so with learning.Behavior and actions, together with cognition, are causations of past events and experiences.
Researches on the introduction of online scafolding and segments of instructional techniques had been prevalent over the decade and yielded positive fndings: an enriching leap towards harnessing communication abilities among student-learners, open and free discussion boards through various modalities of inquiry and deconstruction process that harmonize theories of interaction and discourses in teaching-and-learning.These researches had established positive impact on the academic performance and achievement of the studentlearners towards learning outcomes.
Online learning happens in a community of inquiry in a self-regulated constructive learning environment.Learners interact with varied learning modalities of synchronous and asynchronous activities of rich learning environment.This environment allows cooperative attainment of the learning contents' objectives and the development of personal relationship among the student-learner participants.(Anderson & Elloumi, 2004).
Mediated with online scafolding of instructional delivery, the teacher and learners work together to optimize learning experiences.This provides realistic yet practical opportunities in attaining sustainability in the teaching-learning process through independent and constructive learning.This is necessary as the nature and purposes of Physics instruction needs reinforcement for it had been mystifed as difcult since time inmemorial.Most students hold negative stereotype images of science and technology in general and Physics in particular.
The crux is: science instruction needs to be re-energized by providing challenging units of inquiry among its student-learners -the creation of intuitive learning engages student-learners from the spark of excitement that stems from discovery.This engagement results in more learning as they develop more integrated, useful understanding of concepts and their interrelationships and applicability (Beatly, 2004and Tytler, 2007in Bautista, 2012).

The Online Learning Model
The Online Learning Model developed by Anderson & Elloumi presents the theories and practices of online learning in an academic setting.It presents the two main actors of the educative processes, the teacher and the student-learners, interacting in a constructive learning environment of diferent modalities -synchronous and asynchronous.It further presents the diference between independent and paced collaborative learning modalities.
Asynchronous e-learning modality refers to a student-centered strategy based on constructivist that gives emphasis on peer-to-peer interaction in online learning resources, i.e., LMS, online mentoring, chat room/bulletin group discussion and e-mail exchange.Learning Management System (LMS), which is also known as Course Management System (CMS), hosts online instructional designs and technique in an online platform.
On the other hand, approaches of lesson development that requires the interaction of the student-learner and professors in an online platform are said to be synchronous e-learning.Developmental activities like thread discussion and presentations are done at a specifc hour in order for the student-learners to participate and graded.Platforms may include LMS, online mentoring, chat room/bulletin group discussion.
In independent learning modality, learning happens in a sequenced and directed or structured learning environment putting the content as the heart of the process.The teacher controls the content where the student-learner interacts.
On the contrary, learning happens in a community of inquiry in a self-paced cooperative learning.Learners interact with varied learning modalities of synchronous and asynchronous activities of rich learning environment.This environment allows cooperative attainment of the learning contents' objectives and the development of personal relationship among the student-learner participants.
Examples of the synergy developed in these sequences, but not limited to the following, pave for more success towards the students' tasks towards independent learning: creativity through association, drill and exercises, behaviors through simulation, feedback and practice, sound judgment from received feedbacks and coaching among their peers, analysis, deconstruction and practice to both synchronous and asynchronous learning activities.
Astutely, learning is made meaningful and interactive.It leverages higher-learning that involves cognitive and metacognitive learning strategies.Social presence is cognizant to the development of personal meaning -the development of new cognitive and metacognitive knowledge, skills and attitudes as the student-learners interact with the focal point of the inquiry in a constructive learning environment.This cognition is critical to the creation of a sagacious sense of presence that sustains a community of inquiry among the online learners, thus promotes transformational learning (Murphy and Cifuentes, 2001) in Anderson and Elloumi (2004).

The Social Learning Theory
Bandura's Social Learning Theory presents the interrelationship of observation and modeling of behaviors, attitudes, and emotional reactions of others in the learning process of an individual learner.The theory posits that human behavior is learned observationally through modeling: from observing others one forms an idea of how new behaviors are performed, and on later occasions this coded information serves as a guide for action."Social Learning Theory (SLT) is also infuenced by reciprocal causation: the person, behavior and environment are infuencing each other through self-efcacy and self-regulation.Learning employs self-confdence towards learning (self-efcacy) under circumstances of an individual's personal ideas on the appropriateness and inappropriateness of actions in improving his own behaviors (self-regulation).Self-regulation involves modeling (doing what others do both live model and symbolic models) and imitation (using another learner's behavior as a discriminating stimulus both vicarious reinforcement and vicarious punishment).Therefore, SLT spans to both cognitive and behavioral frameworks by encompassing attention, memory and motivation.Hence, the central role of social learning is on behavioral interpretation of modeling.These leaps are link to the Social Development (Vygotsky) and Situated Learning (Lave) Theories.
Social Development Theory posits that the social interactions made by a student-learner precede development, consciousness and cognition.Hypothesizing that cognition and development are the end product of socialization and social behaviors, the theory posits the following tenets: (1) Social interaction plays a fundamental role in the process of cognitive development.Vygotsky felt social learning precedes development.He states: "Every function in the child's cultural development appears twice: frst, on the social level, and later, on the individual level; frst, between people (interpsychological) and then inside the child (intrapsychological);" (2) The More Knowledgeable Other (MKO).The MKO refers to anyone who has a better understanding or a higher ability level than the learner, with respect to a particular task, process, or concept.The MKO is normally thought of as being a teacher, coach, or older adult, but the MKO could also be peers, a younger person, or even computers.(3) The Zone of Proximal Development (ZPD).The ZPD is the distance between a student's ability to perform a task under adult guidance and/or with peer collaboration and the student's ability on solving the problem independently.According to Vygotsky, learning occurred in this zone.(Vigotsky, 1978 as cited in http://www.learning-theories.com/vygotskys-social-learning-theory.html).
Situated Learning Theory argues that learning is a function of various activities, contexts and culture of inquiry under social interactions in a process of "legitmate peripheral participation.Social interaction is a critical component of situated learning.Student-learners are invited to come across learning in a "community of practice" which embodies certain beliefs and behaviors to be observed and practiced.As student-learners involve themselves in the process of cognitive inquiry, they become more active and engaged within each interaction.Hence, the student-learners assume roles in the learning environment which is usually unintentional rather than deliberate.(Lave, 1988 as cited in http://www.learning-theories.com/situatedlearning-theory-lave.html).

Objectives Of The Study
This study was designed to determine the learning impact of online scafolding in the sustenance of a community of inquiry in Physics instruction.
Specifcally, it attempted to provide explanations of the following: • What are the a-priori learning experiences of the student-learners in synchronous and asynchronous online scafolding?
• Is there a signifcant relationship between the students' a priori experiences and the characteristics of their success in online scafolding of teaching and learning?
• What is the impact of the online scafolding on the students' success in achieving the course' learning outcomes?
• How do the student-learners perceive the relative magnitude of advantages of the online scafolding of teaching and learning?

DESIGN/METHODOLOGY/APPROACH
The Descriptive-Correlational Research Design was used in this study.The results provided bases in the establishment of the relationship between the independent variables and dependent variables of the study.It elucidated on the impact of the embedded online instructional segment to the students' success in achieving select course intended learning outcomes through modalities of online scafolding.The online instructional segments used in this study were LMS, online mentoring, chat room/bulletin group discussion and e-mail exchange; all were done in the e-learning facility of the university, together with the personal e-mail of the researcher.This study was conducted at the Natural Science Department of the Center for General Education, during the second trimester, SY 2012 -2013.The respondents of this study were the 2 sections of NATSC1D (University Physics 1) handled by the proponent.The frequency counts, mean and Pearson-r correlation were used in the treatment of the data gathered to conclude on the stated problems of the study.
A questionnaire formulated by Anderson and Elloumi (2004) was adopted to determine the learning impact of the embedded online segments and experiences through online platforms to the learning experiences of students.
Students' academic performance towards the course was determined by their performance in one of the major examinations (Midterm Examination).The test instrument was formulated based on a two-way Table of Specifcation and assessed through the internal moderation used by the university.The instrument was validated by the course coordinator, together with other teachers teaching the subject, and the department head of Natural Sciences.The modalities of classroom instruction ofered in a constructive learning environment were synchronous and asynchronous.The Social Learning Theory of Bandura, together with Social Development (Vygotsky) and Situated Learning (Lave) Theories, was the recuperating basis in regulating the pace of the instructional design of the class program.
These leaps are expected to reshape the Physics instruction in the sustenance of the classroom's community of inquiry.

RESULTS AND DISCUSSION
Table 1 presents the a-priori learning experiences of the student-learners in synchronous and asynchronous online learning activities.As gleaned on the table, the respondents are exposed to online platforms and other social networking sites with a composite mean of 3.64 and interpreted as often.However, it can be noted that the students seldom (mean = 3.32) use social and communications tools, like online dating, friends reunited, among others, due to the respondents' cultural endowment and restrictions.It can be construed then that the students had rich e-learning experiences and were social butterfies in leading social network that employ online discussion.In an interview with the respondents, they admitted that they ofen join online discussion as they could freely express themselves without any reservation of being wrong.Some of the respondents revealed that they were just observers and do not participate in the discussion.However, they revealed that they learn in the threads of discussion.This phenomenon is supported by Bandura (1986) in his Social Learning Theory.It posits that learning cognition, which is based on cognitive processes, transforms the individual through imitation, modeling and feedback consists of environmental, individual and other social stimulus that are believed to reshape the learning environment of the student-learner.

Mean
Table 2 presents the relationship between the students' a-priori learning experiences and the characteristics of their success in online discussion.It presents that their a-priori learning activities that include online chat, virtual world, among others, made them succeed in the online discussions conducted.It can be said that the students who were exposed to online discussion portals were the students who were receptive and participative to the e-learning activities conducted.The test results show that there is a highly signifcant relationship between the two variables: r-value of .842and a p-value of < .001at .01 level of signifcance.Hence, the null hypothesis of no signifcance diference between the students' a-priori learning experiences and their success' characteristics in online discussion is hereby rejected.

This result is similar to the fndings of Anderson (2006), Anderson and Elloumi (2004), Bautista (2012) and Ryan-Rojas, et al (2012) in their studies on online delivery techniques of instruction.They concluded that the learning behaviors of the students in online discussion are controlled by their computer playfulness and online cognition.Presented in the foregoing table is the learning impact of online scafolding to their performances to class participation, formative assessment and summative evaluations.

Independent
It presents that the indicators of the online scafolding techniques done honed their performances in the class as indicated by the r-values and the p-values at .05 and .01levels of signifcance.Results showed a highly to very highly signifcant positive correlations.Hence, the null hypothesis of no signifcant impact on the success of achieving select course intended learning outcomes in Physics is hereby rejected.
These fndings post similar results of Anderson (2006), Anderson and Elloumi (2004), Aguado, Barrutia & Echebarria (2012), Bautista (2012), Langenhorst (2012) and Ryan-Rojas, et al (2012) in their studies on online delivery technique.The involvement of leveraging and harnessing students' prior e-learning experiences in integrating new ideas and information in constructing a body of knowledge cognizant to enhancing the over-all students learning in a collegial, constructive and democratic learning environment were categorically articulated.
On the other hand, the interaction models of online Learning of Anderson and Elloumi (2004) and the time and place dimensions of online delivery systems of Duderstadt (1997) in O'Malley & McCraw (2000) can be posited as bases of this cognition process where learning takes place in a community of inquiry.Knowing that learners learn in varied modalities of creativity, deconstruction and sound judgment to feedback on the threads of discussions during on-line scafolding sustains a community of inquiry among students.Hence, learning is enforced as continuous research and investigation are to be done.
Table 4 presents the perceived satisfaction of the student-learners to the online scafolding in their learning activities in Physics.It can be gleaned on the table that the student-learners' were satisfied (Composite Mean = 3.68) with their various learning activities.
These behaviors towards online learning were the results of direct to indirect discussion that leads to mental cognition and learning behaviors.Cognition is believed to reshape the learning environment of the studentlearner by transforming the individual's learning schema through imitation, modeling and feedback consists of environmental, individual and other social stimulus.Learning in this condition is based on collaborative social interaction and social construction of knowledge by enabling the students to acquire and develop cognition as they get involved in a community of practice in a "legitimate peripheral participation" (Brown, et al., 1989) in Anderson (2006).
The notion of interaction must become the integral concept of both learning and computer mediation in classroom instruction.Interaction refers to reciprocal events involving at least two actors and/or objects and at least two actions in which the actors, objects, and events mutually infuence each other.Hence, verbal immediacy behavior is still the central concept of reciprocal events and mutual response if an online platform is to enhance communication skills among students in fostering active participation (Shea, Swan, Fredericksen & Pickett, 2002;Swan, 2003;Schiederig, 2007).Concomitantly, the teacher still plays an important role as the teacher's feedback and interaction is still essential to facilitate learning since students are vulnerable to generate signifcant ideas.Hence, teachers must be fexible enough in the switch response categories in the analysis of problem, proposition, statement, among others (Sloan Consortium, 2002;Anderson, 2006;Laverty, Wood, Tannehill, Kohun & Turchek, 2012).

Mean
The integration of online platforms in classroom instruction paved favorable avenues in meeting the demands of the digitals years of academic institutions.Benefts are reasonably keystones in the progression of collaborative social interaction and social construction of knowledge in sustaining a community of inquiry in Physics instruction.It must pave avenues for divergent and refective independent learning skills.
Table 5 presents the general perception of the respondents on the benefts of online scafolding to their learning tasks in sustaining a community of inquiry beyond classroom hours.It presents that the students had a general perception of 3.76 and interpreted as advantageous.These results could validate fndings and analysis of online segments on educational technologies whether or not students develop esteem the ability to articulate and replicate their insights through refective thinking and reasoning at their own pace, and the progression of background knowledge in a dialogical learning environment (Bautista, 2012).While learning in online segments occurs socially within the vicarious interaction of the learning platform, students' learning is attributed to the number and superiority of inquiry supportive of divergent thinking, exploration and refection (Swan, 2003).Hence, the teacher, as facilitator of student learning, plays a critical role in order to reap and reduce the drawbacks of the contrasting learning modes of student-learners in an online platform.

CONCLUSIONS
Based on the fndings of the study, the following are concluded: (1) The student-learners had rich a-priori elearning experiences in the virtual world and online discussion portals; (2) The students' a-priori e-learning experiences was a highly positively correlated with characteristics of their success in online scafolding; (3)
