Confirmation Reports >> Methods
The Methods delineates the experimental or mathematical procedures and steps performed in the research study. Preceded by Introduction and Literature Review and followed by Preliminary Findings and Significance and Implications, the Methods is crucial in a confirmation report. The section heading can be either a generic name or a specific name in the form of a noun phrase that describes the experiment or the algorithm. Students who have not developed the methods in full during the preliminary stage of the study may opt to use a generic name as the section heading. The title for the Methods may vary and alternative headings include:
- Algorithm;
- Experimental Design;
- Materials and Methods;
- Methodology; and
- System Model and Problem Formulation.
The length and organisation of the Methods vary across studies. Even within the same discipline, confirmation reports can be heterogeneous, depending on the design and purpose of the study. In general, this chapter should describe the experiment and/or calculation in a step-by-step manner with adequate details. This is to enable the replication of the experiment and/or the re-performing of calculation steps.
Many supervisors think that the Methods is the most important chapter in a confirmation report. This is because in the initial stages of the research study, the assessment of the feasibility and expected results and significance of the study focusses on the research design. The Methods explicates the research design which involves experiments and/or algorithms in an organised and logical manner. Procedural choices and considerations are spelt out with justifications.
For confirmation reports without preliminary results, the Methods provides the examiners with necessary information to assess the feasibility, the expected validity, and the generalisability of the study. The Methods therefore needs to be organised carefully and written clearly, reflecting the nature and logic of the research design. Any imprecise description or omission of a step could be detrimental to the examiner’s assessment of the confirmation report.
In summary, the main purposes of the Methods in a confirmation report include the following:
- enabling examiners to assess the feasibility and the generalisability of the research design by describing the materials involved in the experiments, experimental and calculation steps, and data analysis procedures sequentially and logically
- establishing the validity for the preliminary results by justifying the choices of materials used and procedural choices made in the experiments or the algorithm calculation; and,
- allowing the replication of the preliminary experiment(s) or the re-verification of the algorithm(s) by providing sufficient details of the experimental setup as well as the experimental and calculation steps
Requirements for different universities and different disciplines may vary. Please refer to the university guide or consult with the supervisor for clarification about the requirements.

Option A is incorrect. The Methods is a necessary section. Parts in the research design that are not fully developed should still be described and justified with pending considerations.
Option B is incorrect. Details of other possible solutions are not necessary. Irrelevant or supplementary information may impede the logical flow in the Methods.
Option E is incorrect. Procedural choices have to be justified so as to establish the expected credibility and validity of the study.
The Methods is an indispensable section in a confirmation report. It is often preceded by Introduction and Literature Review and followed by Preliminary Findings or Expected Results and Significance.
The structure of the Methods varies because different types of scientific studies follow different research design structures. The number and contents of the sub-sections depend on the scale and nature of the scientific quest. For instance, the Methods for examining a substance used in construction work probably involves descriptions of chemicals and physical experimental procedures whilst that for putting forward an algorithm tested with computers does not. In general, the structure of the Methods depends on the nature of the study, i.e. whether it is experimental-based or algorithm-based.
In experimental studies involving materials, the Methods usually contains three moves, which are, in their typical order:
- Materials Source and Collection;
- Experimental Procedures; and,
- Data Analysis Procedures.
In algorithm-based studies, the Methods mainly consists of
- Preliminaries; and,
- Algorithm.
The above moves in both structures may appear in the same study. The moves should be presented according to the actual or the proposed sequence of the experimental procedure, exhibiting a logical flow in the section. The length of a move may vary from a few sentences to even several few paragraphs. A set of moves (e.g. Preliminaries and Algorithm) may be repeated in a cyclical manner to reflect the experimental design.
To improve the logical flow of the text, introductory and transitional paragraphs may be inserted to connect the major moves and/or different sub-sections. These paragraphs usually provide background information and outline the main procedures, helping readers form expectations of the contents and increasing the readability.
To better understand the writing requirements of confirmation reports, the guidelines from the university should be consulted and advice from the supervisor(s) should also be sought. Confirmation reports for studies of the same nature from the same discipline can serve as references.
Moves for Experimental Studies Involving Materials
The description of an experimental study involving materials usually needs the details of materials needed in the experiment, experimental setup and steps, and the methods for analysing data obtained from the experiment. Possible moves in this type of studies are shown in their typical order as follows.
MOVE 1 Materials Source and Collection
The move contains precise descriptions of properties of materials used or examined in the experiment and methods of collecting or obtaining them.
MOVE 2 Experimental Procedures
The move details the conditions for experiments and configurations for the experimental apparatus. Experimental procedures and steps are spelt out in sequential order with justifications. Each experimental step is elaborated to an extent that convinces the readers of its feasibility and expected validity.
MOVE 3 Data Analysis Procedures
This move describes the procedures of data analysis. It may involve physical examination, observation or statistical analyses, are explained in detail in this move. This is to form expectations of the types of results and findings.

3. Methodology NOTE 1 Chemicals. NOTE 2 DMP (> 99% purity) and hydrogen peroxide (35%, w/w) were purchased from Sigma Aldrich Inc., USA. All the chemicals used in this study were of A.R. grade and all solvents were of HPLC grade and used without purification. Sulfuric acid and sodium hydroxide were used for pH adjustment. The deionized-distilled water used throughout all the experiments was obtained from a Millipore Waters Milli-Q water purification system. The initial concentration of the DMP solution was 0.05 mM in all tests, and the initial pH was 6.5 ± 0.2, unless stated otherwise. NOTE 3 |
2. Experimental Procedures |
Sonolysis. NOTE 4 The sonolysis experiments were performed in a stainless steel jacketed cubic groove reactor with an effective volume of 1.5 L (tailor-made by Ning Bo Scientz Biotechnology Co., China) (see Fig. 1). Ultrasound at a frequency of 400 kHz and 120 W (nominal output power) was applied from the bottom of the reactor through six piezoelectric ceramics […] NOTE 5 Photolysis. NOTE 6 An aluminum photoreaction chamber […] was employed for the photolysis process, in which six lamps (maximum) can be installed on the ceiling of the chamber. In addition, a ventilation fan was installed in the chamber to prevent heat accumulation. […] NOTE 7 Sonophotolytic reaction. NOTE 8 The simultaneous US/UV (sonophotolytic) reaction was realized by placing the sonicator (i.e. the reactor) inside the photo-chamber […]. The sequential tests involving either UV followed by US, or vice versa, were carried out by respectively switching on/off either the sonicator or UV lamps, for given time periods. NOTE 9 |
3. Data Analysis Procedures |
Analysis. NOTE 10 During irradiation, 1.0-2.0 mL aliquots were withdrawn from the reactor at predetermined time intervals for further analysis. NOTE 11 The DMP concentration was quantified by HPLC (Waters 717), consisting of a pump (Waters 515), a UV detector (Waters 2489), an auto sampler (Waters 717), and a Brava C18-BDS column (5µm, 25 × 0.46 cm). […]The concentration of H2O2 was determined by measuring the absorbance of titanium peroxide (TiO22+) complex […]. All the experiments were conducted at room temperature (air-conditioned at 24 ± 1 ºC) in duplicate and the error is less than 5%. NOTE 12 |

Moves for Algorithm-based Studies
Algorithm-based studies usually involve modelling and simulation with a computer instead of experimenting with physical substance. The description of an algorithm-based study contains detailed calculation steps of an algorithm, which includes all essential calculation that provides the foundation upon which the algorithm is built. Possible moves in this type of studies are shown as follows:
MOVE 1 Preliminaries
This move provides the mathematical and other essential information needed for developing the algorithm. It may contain calculation steps for proving theorems mathematically. The mathematical data is a prerequisite for developing the desired algorithm.
MOVE 2 Algorithm
The move describes the details of the proposed algorithm. It helps readers understand the scope of the mathematical problem and possible ways to resolve the problem.

Understanding Language Features with Examples – Words and Phrases for Linking Ideas
Below are extracts from confirmation reports in the fields of Civil and Environmental Engineering, Electrical Engineering, Electronic and Information Engineering, and Systems Engineering and Engineering Management.
When writing the methods in a confirmation report, different constructs (e.g. facts, ideas, and opinions) need to be linked according to their relationships so as to justify a procedural choice, present experimental setups in sequence, and explain the methods in collecting and interpreting data and results.
Using a range of useful words and phrases, messages can be conveyed clearly, constituting a logical flow of ideas and achieving coherence and cohesiveness in writing.

The writing of confirmation reports requires clarity so as to delineate ideas without any textual ambiguity. An ambiguous or faulty pronoun reference occurs when there is more than one possible reference in the sentence and/or the preceding sentence.
The following extract contains examples of ambiguous pronoun references (pronouns highlighted in green; possible referents highlighted in yellow).
The circuit diagram of the proposed active quasi-circulator is shown in Fig. 2. Its typology is similar to that formed by cascading four single stage distributed amplifiers. However, here it was formed by connecting three single stage BJT DAs together with a T-network phase shifter. |
Explanatory Notes Its This possessive pronoun may refer to either “circuit diagram” or “proposed active quasi-circulation”. To avoid the ambiguity, “Its typology” can be rewritten as “The typology of [the referent]”. It The pronoun may refer to either “Its typology” or “the proposed active quasi-circulator”. To avoid the ambiguity, the relevant referent should be stated in full. |
