ABSTRACT

The flow in using the language of Chemistry is an important tool for students. Chemical formula is not a descriptive tool but also a heuristic tool. Most of the Secondary School students face challenges with Chemical formula (naming and writing). Inappropriate use of symbolic representation is the most common problem faced by students in Grade nine. The objective of the present paper is to enable Grade nine students to name and write the formula of Chemical compounds correctly. It is an attempt to investigate the complications faced by the students in formative assessment to acquire intended learning outcomes. To enhance the conceptual understanding and intended learning outcomes small group remedial teaching with experiential learning activities and worksheets are used. Small group work is used as a strategy to improve the learning outcomes and conceptual understanding among the students of Grade nine.  The present study is limited to the students of one school and one unit of Science.  Totally 40 students participate in the study.  Sample students are divided into two group study group and control group equally on the basis of their previous knowledge of the subject.  Students of study group are taught by using small group remedial experiential activity. The present study is experimental in nature.  Data is analyzed by using mean, mean difference and standard deviation.  The vital variance between the mean score of both groups on variables of pre-formative assessment and post-formative assessment score is tested at 0.05 level by applying t-test. The result of the present study reveals that there is a significant positive impact of small group remedial teaching on conceptual understanding of naming and writing the Chemical formulae of Chemical compound in Science subject among the students of Grade nine.  Based on the result of the study teachers must provide small group remedial teaching to the students facing challenges in conceptual understanding to acquire the intended learning outcomes.



 

1.     INTRODUCTION

 

“The capacity to learn is gift. The ability to learn is skill.  The willingness to learn is choice.”   - Brain Herbert.

We are living in the era of Chemicals - sugar is disaccharides, salt is Sodium Chloride, glass is super cold liquid silicates and our stomach contain 1M hydrochloric acid.  Hence it is very important to able to recognize the chemical compound by its name.  Chemical formulas are part of chemistry’s everyday language but it’s like a foreign to novice students.  Teachers and experts switch between many types of formulas, systematic names and common names for the chemicals. But Secondary School students face difficulties with the chemical formulas. Few students acquire fluency compared to their counterparts while other struggles which in turn hinders the students’ engagement and achievement in Science subject. 

Chemistry is an essential basis for everyday life and has huge unforeseen potential benefits for the future of the society. Sound understanding of the Chemistry provides individuals an opportunity to explain the life around us and take decision concerning our actions as individuals.  The sound understanding of Chemistry is essential for working in almost all other Science disciplines - such as Medicine, Engineering, Environmental Science and Material Science etc. The learners, who opt for the career in these fields require sound knowledge in Chemistry and must be updated with the recent trends in Chemistry.

Understanding and learning of Science concepts and principles of Chemistry is difficult. Chemistry is involved in all facets of life and yet it is cursed as much as it is praised. As a Science teacher for almost three decades my mission is to sell Chemistry as an intellectual pursuit and creative Science. It is very unlucky for a teacher that many students experience Chemistry curriculum as abstract, difficult to understand and learn and not appropriately correlated to day today life. Chemistry is widely persuaded as a difficult subject because of its specialized language, abstract nature of concept, mathematical content and amount of content to be learnt.

During the academic year 2018-19 when teaching Science in Grade nine it is observed that the majority of the students face problem in understanding, naming and writing the Chemical formula and hence the central objective of the present study is to enable Grade nine students to name and write the formula of inorganic compound correctly to acquire intended learning outcome of unit four “Atoms and Molecules”. 

The following steps are initiated to enhance students’ performance, satisfaction and motivation level in classroom instructions. 

 

Step 1: Defining problem

Students face difficulties during classroom instruction in applying the acquired concept and conceptual understanding of core concept in writing and naming the formula of inorganic compounds.  After diagnosing the problem, the core objectives of the present paper are fabricated as under:

·        To enable learners to name simple inorganic compound by their chemical formulae.

·        To enable learners to write chemical formulae for simple inorganic compound correctly.

 

Collection of Data

Data is collected to enhance the conceptual understanding and application of concept – High Order Thinking Skill (HOTS) based on revised Bloom’s Taxonomy in naming and writing formula of inorganic compound. Data is collected by using following tools:

·        Formative Assessment – to identify the most common mistake/ error made by the learners.

·        Observation – Students’ participation and involvement in classroom instructions and teaching-learning process.

·        Feedback – to diagnose the difficulties faced by the learners in conceptual understanding and to acquire intended learning outcomes.

 

Step 2: Remedial Measures

Our strategies

To achieve the intended learning objectives and conceptual understanding, the focus is on the following remedial strategies:

 

First: Worksheet (Group Activity)

Worksheet is prepared using various binary compounds. The students of the study group are divided into groups; each group consists maximum of three students and minimum of two. Each group is asked to discuss and write the name and formula of the organic compound in the blank. The present remedial strategy fosters the importance of sharing the learning among them. It fosters team building.  Together everyone achieve more (TEAM). 

The worksheet is fabricated in two sections (A & B). Section A consists of compound and Section B consists of formulae of the compound.

The section A of worksheet is designed for naming the compound by applying the following rules - High Order Thinking Skills (HOTS) based on revised Bloom’s Taxonomy.

1)     Metal + Non-metal – Name of the compounds end with “-ite”

2)     Metal + Poly atomic atom – Name of the compounds end with polyatomic ion.

3)     Transition metal + Non-metal - Name of the compounds end with “-ide”. The charge of the transition metal is presented in roman numerical.

4)     Transition metal + Poly atomic atom –Name of the compounds end with polyatomic ion. The charge of the transition metal is presented in roman numerical.

5)     Non – metal + Non-metal - Name of the compounds end with “-ide”. Prefix as “mono, di, tri…” are used for all elements.

6)     Binary acids ­– Named as hydro…. ioc acid.

Table 2 depicts that calculate t-value is found to be 0.051 which is statistically non-significant and it is less than critical table value at 0.05 level. Hence null hypotheses “There is no noteworthy distinction between the academic achievement of the study group and the control group in the formative assessment before the treatment” is accepted.  It ambiguously reveals that learners of both groups have equally performed in the unit “Atoms and Molecules” when the unit is taught by traditional chalk and talk method.

Table 3 reveals that computed t-value (27.59) is greater than critical table value of t at the level of 0.05.  Hence the null hypotheses “There is no noteworthy distinction between the academic performance of the study group and the control group in the formative assessment after the treatment” is not accepted.  Result of the current study reveals that the students of the study group perform excellently well in the formative assessment conducted after the treatment as compared to the counterpart in control group.  It is further clarified in Fig 3.

Result in Table 4 reveals that the computed t-value (32.89) is higher than the critical t-value at 0.05 level and hence null hypotheses “There is no noteworthy difference between the academic achievement of the study group and the control group in the summative evaluation at the retention test” is not accepted.  In the summative evaluation the students of study group as enhanced than their counterparts in control group.  It is further clarified in Fig 4.

 

4.     CONCLUSION

 

The statistical analysis of the present study arrives at the following conclusion:

1)     Small group remedial experiential activity in teaching-learning process has achieved admirable position in school education and acts as a potential tool to motivate the students in learning and enhances the process of deep learning.  The major characteristics of small group remedial experiential learning activities are to enhance active participation of the students in teaching –learning process and acquire intended learning outcomes.  The essential stimulus in developing small group teaching-learning classroom instructions are considered at class level, group composition, physical climate, existing resources, diagnostics of learning gaps and fabrication of objectives and learning outcomes.

2)     The performance of students in formative assessment after the treatment and summative evaluation are significantly improved, along with deep learning, confidence, self-esteem, competence, positive attitude towards self-learning. 

3)     Small group remedial experiential activities have significant impact on academic achievement of study group and hence it is highly useful due to its fulfillment of individual learning gaps.
